3. Scheduler neu starten: `POST /api/scheduler/start`
## 🗄️ Datenbank-Probleme
### Fehler: Foreign Key Constraint
**Symptom**: `sqlite3.IntegrityError: FOREIGN KEY constraint failed`
**Ursache**: Versuch, referenzierte Datensätze zu löschen
**Lösung**: Abhängigkeiten vor dem Löschen prüfen:
```python
# Vor dem Löschen eines Druckers
active_jobs = db_session.query(Job).filter(
Job.printer_id == printer_id,
Job.status.in_(["scheduled", "active"])
).count()
if active_jobs > 0:
return jsonify({"error": "Es existieren aktive Jobs für diesen Drucker"}), 400
```
### Fehler: Datenbank-Session nicht geschlossen
**Symptom**: `ResourceWarning: unclosed <sqlite3.Connection>`
**Ursache**: Vergessene `db_session.close()` Aufrufe
**Lösung**: Immer `try/finally` verwenden:
```python
db_session = get_db_session()
try:
# Datenbankoperationen
pass
finally:
db_session.close()
```
### Fehler: Unique Constraint Violation
**Symptom**: `sqlite3.IntegrityError: UNIQUE constraint failed`
**Ursache**: Versuch, doppelte Einträge zu erstellen
**Lösung**: Vor dem Einfügen prüfen:
```python
existing = db_session.query(User).filter(User.email == email).first()
if existing:
return jsonify({"error": "E-Mail bereits registriert"}), 400
```

# Häufige Fehler und Lösungen
Dieses Dokument enthält häufig auftretende Fehler und deren Lösungen für das MYP-3D-Druck-Management-System.
## Job-Scheduler und Steckdosensteuerung
### Steckdose kann nicht eingeschaltet werden
**Problem:**
Log-Eintrag: `Fehler beim Starten von Job X: Steckdose konnte nicht eingeschaltet werden`
**Mögliche Ursachen und Lösungen:**
1. **Netzwerkverbindung zu Steckdose unterbrochen**
- Prüfen Sie, ob die Steckdose mit dem Netzwerk verbunden ist
- Ping-Test: `ping [IP-Adresse der Steckdose]`
- Steckdose neu starten (physischer Reset-Knopf)
2. **Falsche Zugangsdaten für Steckdose**
- Überprüfen Sie in der Datenbank, ob die korrekten Zugangsdaten (Benutzername/Passwort) für die Steckdose hinterlegt sind
- Admin-Bereich → Drucker → Steckdosenkonfiguration bearbeiten
3. **PyP110-Bibliothek veraltet**
- Bibliothek aktualisieren: `pip install PyP100 --upgrade`
### Job wird nicht gestartet oder beendet
**Problem:**
Ein geplanter Job startet nicht oder ein laufender Job wird nicht beendet
**Mögliche Ursachen und Lösungen:**
1. **Scheduler-Thread läuft nicht**
- Prüfen Sie den Status des Schedulers im Admin-Bereich
- Wenn nicht aktiv: Scheduler starten
- Bei wiederholtem Problem: Server neu starten
2. **Datenbankprobleme**
- Überprüfen Sie die Datenbank auf Konsistenz
- Backup einspielen, falls notwendig
### Job-Verlängerung funktioniert nicht
**Problem:**
Nach dem Verlängern eines Jobs wird er trotzdem zum ursprünglichen Zeitpunkt beendet
**Lösung:**
1. Prüfen Sie die Datenbankeinträge, ob die `end_at`-Zeit korrekt aktualisiert wurde
2. Prüfen Sie die Log-Dateien auf Fehler beim Aktualisieren des Jobs
3. Verlängern Sie den Job erneut mit größerem Zeitpuffer
## Sicherheitshinweise
### Sicherheitsmaßnahmen bei Stromausfällen
**Wichtig:**
- Bei Stromausfällen kehren die Steckdosen in ihren Standardzustand zurück (meist AUS)
- Nach Wiederherstellung der Stromversorgung wird der Scheduler automatisch Jobs wieder aufnehmen
- Laufende Jobs werden jedoch **nicht** automatisch fortgesetzt, um Schäden zu vermeiden
- Administrator muss laufende Jobs manuell neu starten
### 5-Minuten Sicherheitspuffer
Das System verwendet einen 5-Minuten Sicherheitspuffer, bevor es einen Job beendet. Dies verhindert, dass ein Druck zu früh beendet wird. Die tatsächliche Ausschaltzeit ist also immer 5 Minuten nach der im System angezeigten Endzeit.
## API-Endpunkte für Fehlerbehebung
| Endpunkt | Beschreibung |
|----------|--------------|
| `GET /api/scheduler/status` | Status des Job-Schedulers abfragen |
| `POST /api/scheduler/start` | Scheduler manuell starten (Admin) |
| `POST /api/scheduler/stop` | Scheduler manuell stoppen (Admin) |
| `GET /api/jobs/active` | Alle aktiven Jobs anzeigen |
| `POST /api/jobs/<id>/extend` | Job-Laufzeit verlängern |
| `POST /api/jobs/<id>/finish` | Job manuell beenden (Admin) |
## Flask-Login Fehler
### AttributeError: 'User' object has no attribute 'is_authenticated'
**Problem:**
```
AttributeError: 'User' object has no attribute 'is_authenticated'
```
**Ursache:** Die User-Klasse erbt nicht von `UserMixin` oder implementiert nicht die erforderlichen Flask-Login Attribute.
**Lösungen:**
1. Stellen Sie sicher, dass die User-Klasse von `UserMixin` erbt:
```python
from flask_login import UserMixin
class User(UserMixin, Base):
# ... Rest der Klasse
```
2. Implementieren Sie die erforderlichen Methoden manuell:
```python
@property
def is_authenticated(self):
return True
@property
def is_active(self):
return self.active
@property
def is_anonymous(self):
return False
def get_id(self):
return str(self.id)
```
3. Führen Sie die Datenbankmigration aus:
```bash
python3.11 migrate_db.py
```
### Fehlende username-Spalte
**Problem:** Die Anwendung versucht auf `username` zuzugreifen, aber die Spalte existiert nicht in der Datenbank.
**Lösungen:**
1. Führen Sie das Migrationsskript aus:
```bash
python3.11 migrate_db.py
```
2. Falls die Migration fehlschlägt, initialisieren Sie die Datenbank neu:
```bash
python3.11 init_db.py
```
## Datenbank-Fehler
### SQLite Database is locked
**Problem:**
```
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked
```
**Ursache:** Dieser Fehler tritt auf, wenn mehrere Prozesse gleichzeitig auf die Datenbank zugreifen.
**Lösungen:**
1. Stellen Sie sicher, dass Sie alle Datenbankverbindungen mit `db_session.close()` schließen
2. Verwenden Sie `with get_db_session() as session:` um Sessions automatisch zu schließen
3. Prüfen Sie, ob der Scheduler und die Hauptanwendung gleichzeitig auf die Datenbank zugreifen
### Detached Instance Error
**Problem:**
```
sqlalchemy.orm.exc.DetachedInstanceError: Instance <Job at 0x...> is not bound to a Session
```
**Ursache:** Zugriff auf ein SQLAlchemy-Objekt nach dem Schließen der Session.
**Lösungen:**
1. Verwenden Sie `joinedload` für eager loading: `db_session.query(Job).options(joinedload(Job.user))`
2. Konvertieren Sie Objekte zu Dictionaries, bevor Sie die Session schließen: `job_dict = job.to_dict()`
3. Verwenden Sie `session.expunge_all()` gefolgt von `session.close()`, wenn Sie Objekte weiter verwenden müssen
## Tapo Smart Plug Fehler
### Verbindungsfehler
**Problem:**
```
PyP100.PyP100.P100Exception: Could not connect to device
```
**Ursache:** Smart Plug ist nicht erreichbar oder Authentifizierungsprobleme.
**Lösungen:**
1. Überprüfen Sie die IP-Adresse des Smart Plugs
2. Stellen Sie sicher, dass der Smart Plug eingeschaltet und mit dem WLAN verbunden ist
3. Überprüfen Sie die Zugangsdaten in `config/settings.py`
4. Verwenden Sie einen Try-Except-Block zur Fehlerbehandlung:
```python
try:
p110 = PyP110.P110(ip, username, password)
p110.handshake()
p110.login()
p110.turnOn()
except Exception as e:
printers_logger.error(f"Smart Plug Fehler: {str(e)}")
```
## Flask-Anwendungsfehler
### Interner Server-Fehler (500)
**Problem:** Die Anwendung gibt einen 500-Fehler zurück.
**Ursache:** Verschiedene mögliche Ursachen, von Datenbank- bis hin zu Programmierfehlern.
**Lösungen:**
1. Überprüfen Sie die Logs unter `logs/app/app.log` und `logs/errors/errors.log`
2. Starten Sie die Anwendung im Debug-Modus: `FLASK_DEBUG=True python3.11 app.py`
3. Implementieren Sie bessere Fehlerbehandlung mit Try-Except-Blöcken
### Authentifizierungsfehler
**Problem:** Benutzer können sich nicht anmelden oder erhalten unbefugte Zugriffsfehler.
**Ursachen:**
- Ungültige Anmeldedaten
- Session-Probleme
- Cookie-Probleme
**Lösungen:**
1. Überprüfen Sie die Logs unter `logs/auth/auth.log`
2. Setzen Sie das Passwort zurück mit:
```python
from models import User, get_db_session
db_session = get_db_session()
user = db_session.query(User).filter(User.username == "admin").first()
user.set_password("neues_passwort")
db_session.commit()
db_session.close()
```
3. Löschen Sie Browser-Cookies und -Cache
## CSS und Frontend-Fehler
### Tailwind-Stile werden nicht angewendet
**Problem:** Die Tailwind-Klassen haben keine Wirkung auf das Styling.
**Lösungen:**
1. Stellen Sie sicher, dass die generierte CSS-Datei korrekt eingebunden ist:
```html
<link rel="stylesheet" href="{{ url_for('static', filename='css/tailwind-dark-consolidated.min.css') }}">
```
2. Bauen Sie die CSS-Datei neu: `npm run build:css`
3. Überprüfen Sie in der Browser-Konsole, ob Fehler beim Laden der CSS-Datei auftreten
### Dark Mode funktioniert nicht
**Problem:** Die Dark-Mode-Stile werden nicht angewendet.
**Lösungen:**
1. Stellen Sie sicher, dass das HTML-Element die entsprechende Klasse hat:
```html
<html class="dark" data-theme="dark">
```
2. Überprüfen Sie, ob die Tailwind-Konfiguration Dark Mode aktiviert hat:
```js
// tailwind.config.js
module.exports = {
darkMode: 'class',
// ...
}
```
## Scheduler-Fehler
### Scheduler führt keine Jobs aus
**Problem:** Der Scheduler schaltet Drucker nicht ein/aus wie erwartet.
**Ursachen:**
- Scheduler ist nicht gestartet
- Fehler bei der Tapo-Verbindung
- Fehler in der Scheduler-Logik
**Lösungen:**
1. Überprüfen Sie die Logs unter `logs/scheduler/scheduler.log`
2. Stellen Sie sicher, dass `SCHEDULER_ENABLED = True` in `config/settings.py` gesetzt ist
3. Starten Sie die Anwendung neu
## Performance-Probleme
### Langsame Ladezeiten
**Problem:** Die Anwendung lädt langsam oder reagiert träge.
**Lösungen:**
1. Optimieren Sie Datenbankabfragen mit geeigneten Indizes
2. Reduzieren Sie die Anzahl der Datenbankabfragen durch Eager Loading
3. Implementieren Sie Caching für häufig abgerufene Daten
4. Überprüfen Sie die Logfiles auf übermäßige Logging-Aktivitäten
## Content Security Policy (CSP) Fehler
### Script-src-elem 'none' Fehler
**Problem:**
```
Refused to load the script because it violates the following Content Security Policy directive: "script-src-elem 'none'".
```
**Ursache:** Die Content Security Policy ist zu restriktiv eingestellt und blockiert das Laden von Skripten.
**Lösungen:**
1. Überprüfen Sie die CSP-Konfiguration in `config/security.py`:
```python
'Content-Security-Policy': (
"default-src 'self'; "
"script-src 'self' 'unsafe-eval' 'unsafe-inline' https://cdn.jsdelivr.net https://cdnjs.cloudflare.com; "
"script-src-elem 'self' 'unsafe-inline' https://cdn.jsdelivr.net https://cdnjs.cloudflare.com; "
# ... weitere Regeln
)
```
2. Stellen Sie sicher, dass die CSP in der `after_request`-Funktion richtig angewendet wird:
```python
@app.after_request
def add_security_headers(response):
from config.security import get_security_headers
security_headers = get_security_headers()
for header, value in security_headers.items():
response.headers[header] = value
# CSP-Report-Only Header entfernen
if 'Content-Security-Policy-Report-Only' in response.headers:
del response.headers['Content-Security-Policy-Report-Only']
return response
```
3. Vermeiden Sie mehrere konkurrierende Service Worker Registrierungen, die CSP-Konflikte verursachen können.
### Inline Script Fehler
**Problem:**
```
Refused to execute inline script because it violates the following Content Security Policy directive: "script-src-elem 'none'"
```
**Lösungen:**
1. Fügen Sie 'unsafe-inline' zur script-src Direktive hinzu
2. Alternativ fügen Sie einen Hash oder Nonce für das Inline-Skript hinzu:
```html
<script nonce="{{ csp_nonce }}">
// Inline JavaScript
</script>
```
und in der CSP:
```
script-src 'nonce-{{ csp_nonce }}';
```
### Service Worker Registration Fehler
**Problem:**
```
Refused to create a worker from 'URL' because it violates the following Content Security Policy directive: "script-src 'none'"
```
**Lösungen:**
1. Stellen Sie sicher, dass die `worker-src` Direktive korrekt konfiguriert ist:
```
worker-src 'self' blob:;
```
2. Erstellen Sie die erforderlichen Service Worker Dateien im richtigen Verzeichnis
3. Verwenden Sie einen einheitlichen Ansatz zur Service Worker Registrierung, vorzugsweise im offline-app.js:
```javascript
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/static/js/sw.js')
.then(function(registration) {
console.log('Service Worker registriert:', registration.scope);
})
.catch(function(error) {
console.log('Service Worker Registration fehlgeschlagen:', error);
// Fallback
});
});
}
```
### Icon 404 Fehler
**Problem:**
```
Failed to load resource: the server responded with a status of 404 (NOT FOUND)
Error while trying to use the following icon from the Manifest: URL (Download error or resource isn't a valid image)
```
**Lösungen:**
1. Erstellen Sie die fehlenden Icon-Dateien im Verzeichnis `static/icons/`
2. Aktualisieren Sie das Web App Manifest, um nur verfügbare Icons zu referenzieren:
```json
"icons": [
{
"src": "/static/icons/mercedes-logo.svg",
"sizes": "192x192",
"type": "image/svg+xml"
}
]
```
3. Verwenden Sie Tools wie Lighthouse, um fehlende PWA-Ressourcen zu identifizieren
## JavaScript-Referenzfehler
### Problem: Nicht definierte Funktionen in admin-panel.js
Fehlermeldungen wie "Uncaught ReferenceError: loadPrinters is not defined" können auftreten, wenn Funktionen in der JavaScript-Datei verwendet, aber nicht definiert werden.
**Lösung:**
- Implementiere die fehlenden Funktionen (loadPrinters, loadSchedulerStatus, loadSystemStats, loadLogs, loadUsers, etc.)
- Stelle sicher, dass alle aufgerufenen Funktionen im richtigen Scope definiert sind
- Überprüfe die Reihenfolge der Funktionsdefinitionen und -aufrufe
### Problem: Funktionen in anderen Dateien werden nicht gefunden
Fehler wie "Uncaught ReferenceError: refreshJobs is not defined" in jobs.html oder "exportStats is not defined" in stats.html.
**Lösung:**
- Stelle sicher, dass die Funktionen in der jeweiligen HTML-Datei oder in einer eingebundenen JavaScript-Datei definiert sind
- Überprüfe, ob die JavaScript-Dateien korrekt in der HTML-Datei eingebunden sind
- Nutze konsistente Namenskonventionen für Funktionen
## Service Worker Fehler
### Problem: Cache-API kann mit chrome-extension URLs nicht umgehen
Fehler: "Uncaught (in promise) TypeError: Failed to execute 'put' on 'Cache': Request scheme 'chrome-extension' is unsupported"
**Lösung:**
- Überprüfe die URL-Protokolle bevor du Cache-Operationen durchführst
- Füge eine spezielle Behandlung für chrome-extension-Protokolle hinzu
- Verwende try-catch-Blöcke, um Fehler bei der Cache-Handhabung abzufangen
```javascript
if (url.protocol === 'chrome-extension:') {
// Spezielle Behandlung für chrome-extension URLs
try {
return await fetch(request);
} catch (error) {
console.error('Failed to fetch from chrome-extension:', error);
return new Response(JSON.stringify({
error: 'Fehler beim Zugriff auf chrome-extension',
offline: true
}), {
status: 400,
headers: { 'Content-Type': 'application/json' }
});
}
}
```
## API-Endpunkt Fehler
### Problem: API-Ressourcen werden nicht gefunden (404)
Fehlermeldungen wie "Failed to load resource: the server responded with a status of 404 (NOT FOUND)"
**Lösung:**
- Überprüfe die API-Routen im Backend
- Stelle sicher, dass die API-Endpunkte korrekt implementiert sind
- Überprüfe die Anfrage-URLs in den Frontend-Skripten
- Füge Fehlerbehandlung für fehlende Ressourcen hinzu
## Frontend-Rendering Fehler
### Problem: Fehler beim Laden der Admin-Statistiken
"Error loading admin: admin-panel.js:484 Fehler beim Laden der Admin-Statistiken"
**Lösung:**
- Implementiere ordnungsgemäße Fehlerbehandlung in API-Anfragen
- Zeige benutzerfreundliche Fehlermeldungen an
- Füge Fallback-Werte für fehlende Daten hinzu
```javascript
try {
const response = await fetch('/api/admin/stats');
if (!response.ok) {
throw new Error('Fehler beim Laden der Admin-Statistiken');
}
const data = await response.json();
// Daten verarbeiten
} catch (error) {
console.error('Error loading admin stats:', error);
showNotification('Fehler beim Laden der Admin-Statistiken', 'error');
}
```
## Icon/Ressourcen Fehler
### Problem: Icon-Dateien werden nicht gefunden
"Error while trying to use the following icon from the Manifest: http://127.0.0.1:5000/static/icons/icon-144x144.png"
**Lösung:**
- Überprüfe, ob die Icon-Dateien im richtigen Verzeichnis vorhanden sind
- Stelle sicher, dass die Pfade in der Manifest-Datei korrekt sind
- Füge Fallback-Icons für den Fall hinzu, dass die primären Icons nicht geladen werden können
## Allgemeine Fehlerbehebung
1. **Browser-Konsole prüfen**: Die meisten JavaScript-Fehler werden in der Browser-Konsole angezeigt (F12 oder Rechtsklick -> Untersuchen -> Konsole)
2. **Netzwerk-Tab prüfen**: Im Netzwerk-Tab des Browsers können fehlgeschlagene API-Anfragen identifiziert werden
3. **Codestruktur überprüfen**: Stelle sicher, dass alle Funktionen in der richtigen Reihenfolge definiert werden
4. **Fehlerbehandlung verbessern**: Implementiere try-catch-Blöcke für alle asynchronen Funktionen
5. **Browser-Cache leeren**: Manchmal können Probleme durch veraltete gecachte Dateien verursacht werden
## 404 Fehler (Seite nicht gefunden)
### Fehlende Routen oder API-Endpunkte
**Problem:**
Die Anwendung zeigt 404-Fehler für bestimmte Routen wie `/privacy`, `/terms`, `/my/jobs`, `/api/user/export` oder `/api/user/profile`.
**Ursachen:**
- Die Route wurde nicht korrekt in `app.py` oder dem entsprechenden Blueprint registriert
- Bei API-Endpunkten: Die alte API-Route wurde verwendet, aber die Anwendung nutzt jetzt eine neue Route
- Möglicherweise wurden die Templates erstellt, aber die Routen dafür fehlen
**Lösungen:**
1. **Für öffentliche Seiten** (`/privacy`, `/terms`):
- Überprüfen Sie, ob die Routen in `app.py` definiert sind
- Stellen Sie sicher, dass der `@login_required` Decorator entfernt wurde, falls diese Seiten öffentlich sein sollen
- Prüfen Sie, ob die entsprechenden Template-Dateien unter `templates/` existieren
2. **Für Benutzer-spezifische Seiten** (`/my/jobs`):
- Fügen Sie eine Route hinzu, die zur Jobs-Seite mit vorgefiltertem Benutzer-Parameter weiterleitet
3. **Für API-Weiterleitungen** (`/api/user/export`, `/api/user/profile`):
- Erstellen Sie Weiterleitungsrouten, die zu den neuen Blueprint-Routen führen
- Beispiel: `/api/user/export` sollte zu `/user/export` weiterleiten
4. **Debugging von Routen:**
- Mit `flask routes` können Sie alle registrierten Routen auflisten
- Überprüfen Sie die Log-Dateien auf fehlgeschlagene Routenzugriffe
- Im Debug-Modus starten: `FLASK_DEBUG=True python3.11 app.py`
5. **Blueprint-Registrierung prüfen:**
- Stellen Sie sicher, dass alle Blueprints korrekt in `app.py` registriert sind:
```python
from blueprints.user import user_bp
app.register_blueprint(user_bp)
```

# Chart-Integration mit ApexCharts
Dieses Dokument beschreibt die Integration von ApexCharts in die MYP-Plattform zur Visualisierung von Daten.
## Übersicht
Die MYP-Plattform nutzt [ApexCharts](https://apexcharts.com/) für die Darstellung von Diagrammen und Visualisierungen. ApexCharts ist eine moderne JavaScript-Bibliothek zur Erstellung interaktiver Diagramme mit einem einfachen API und reaktionsfähigem Design.
## Dateien und Struktur
Die Chart-Integration besteht aus folgenden Komponenten:
1. **ApexCharts-Bibliothek**: `static/js/charts/apexcharts.min.js`
2. **Konfigurationsdatei**: `static/js/charts/chart-config.js`
3. **Renderer**: `static/js/charts/chart-renderer.js`
4. **Adapter**: `static/js/charts/chart-adapter.js`
### Funktionsweise
1. Die **Chart-Konfiguration** definiert Standardstile, Farben und Optionen für alle Diagrammtypen.
2. Der **Chart-Renderer** verwaltet die Erstellung, Aktualisierung und Zerstörung von Diagrammen.
3. Der **Chart-Adapter** verbindet die bestehende `renderChart`-Funktion mit der neuen ApexCharts-Implementierung.
## Verwendung in Templates
Um ein Diagramm in einer Template-Datei anzuzeigen:
```html
<div id="mein-chart" class="h-64" data-api-endpoint="/api/pfad/zu/daten" data-chart data-chart-type="line"></div>
```
### Verfügbare Attribute:
- `data-chart`: Markiert das Element als Diagramm-Container
- `data-api-endpoint`: Der API-Endpunkt, von dem Daten geladen werden
- `data-chart-type`: Der Diagrammtyp (optional, wird sonst automatisch bestimmt)
## Unterstützte Diagrammtypen
Die folgenden Diagrammtypen werden unterstützt:
- `line`: Liniendiagramm
- `area`: Flächendiagramm
- `bar`: Balkendiagramm
- `pie`: Kreisdiagramm
- `donut`: Ringdiagramm
- `radial`: Radialdiagramm
## Datenformat
Die API-Endpunkte sollten Daten in einem der folgenden Formate zurückgeben:
### Für Kreisdiagramme (pie/donut):
```json
{
"scheduled": 12,
"active": 5,
"completed": 25,
"cancelled": 3
}
```
### Für Balkendiagramme:
```json
[
{
"printer_name": "Drucker 1",
"job_count": 25,
"print_hours": 124.5
},
{
"printer_name": "Drucker 2",
"job_count": 18,
"print_hours": 85.2
}
]
```
### Für Linien- und Flächendiagramme:
```json
[
{
"date": "2023-01-01",
"value": 42
},
{
"date": "2023-01-02",
"value": 58
}
]
```
## Theme-Unterstützung
Die Diagramme unterstützen automatisch das Light- und Dark-Mode-Theme der MYP-Plattform. Bei einem Themenwechsel werden alle aktiven Diagramme mit den passenden Farben aktualisiert.
## Anpassung
Um die Diagramme anzupassen:
1. **Farben**: Anpassungen in `MYP_CHART_COLORS` in `chart-config.js`
2. **Standardoptionen**: Änderungen in `getBaseChartOptions()` in `chart-config.js`
3. **Spezifische Diagrammtypen**: Anpassungen in den jeweiligen Funktionen (`getLineChartConfig`, `getPieChartConfig`, etc.)
## Erweiterung
Um weitere Diagrammtypen oder Funktionen hinzuzufügen:
1. Fügen Sie eine neue Konfigurationsfunktion in `chart-config.js` hinzu
2. Erweitern Sie die `createChart`-Funktion in `chart-renderer.js`, um den neuen Diagrammtyp zu unterstützen
3. Aktualisieren Sie den `chart-adapter.js`, um die Datentransformation für den neuen Diagrammtyp zu unterstützen

# Tailwind CSS Konfiguration für MYP Platform
Dieses Dokument beschreibt die aktuelle Tailwind CSS Konfiguration und Build-Prozesse für die MYP Platform.
## Struktur
Die CSS-Assets des Projekts sind wie folgt strukturiert:
```
static/
css/
input.css # Tailwind Direktiven & benutzerdefinierte Styles
components.css # Wiederverwendbare UI-Komponenten
tailwind.min.css # Kompiliertes Light-Mode CSS (minimiert)
tailwind-dark.min.css # Kompiliertes Dark-Mode CSS (minimiert)
```
## Tailwind Konfiguration
Die Konfiguration wird durch die Datei `tailwind.config.js` im Hauptverzeichnis des Projekts definiert. Diese enthält:
- Farbpalette mit Mercedes-Benz Farben
- Erweiterungen für Schriften, Schatten und Animation
- Dark-Mode-Konfiguration über die Klasse `dark`
## Build-Befehle
### Light Mode CSS (Standardtheme)
Um das Standard-Light-Mode CSS zu erstellen:
```bash
npx tailwindcss -i ./static/css/input.css -o ./static/css/tailwind.min.css --minify
```
### Dark Mode CSS
Um das Dark-Mode CSS zu erstellen:
```bash
npx tailwindcss -i ./static/css/input.css -o ./static/css/tailwind-dark.min.css --minify --dark-mode 'class'
```
## Verwendung im Projekt
Beide CSS-Dateien werden im `<head>` der Seite eingebunden:
```html
<link href="{{ url_for('static', filename='css/tailwind.min.css') }}" rel="stylesheet">
<link href="{{ url_for('static', filename='css/tailwind-dark.min.css') }}" rel="stylesheet">
```
## Dark Mode Funktionalität
Der Dark Mode wird durch JavaScript in `ui-components.js` gesteuert, welches:
1. Benutzereinstellungen in `localStorage` speichert
2. Systemeinstellungen beobachtet (via `prefers-color-scheme`)
3. Eine `dark`-Klasse zum `<html>`-Element hinzufügt/entfernt
4. Ein Tastaturkürzel (Strg+Shift+D) zum Umschalten bereitstellt
## Entwicklung
Bei der Entwicklung neuer Komponenten:
1. Füge Tailwind-Klassen direkt zu HTML-Elementen hinzu
2. Für wiederverwendbare Komponenten, nutze die `@apply`-Direktive in `components.css`
3. Nach Änderungen müssen beide CSS-Dateien neu gebaut werden
## Voraussetzungen
- Node.js und npm müssen installiert sein
- Python 3.11 und Flask müssen installiert sein
## Projektstruktur
Die Tailwind-Integration besteht aus folgenden Komponenten:
```
app/
├─ static/
│ ├─ css/
│ │ ├─ input.css # Quelldatei für Tailwind
│ │ ├─ tailwind-dark-consolidated.min.css # Generierte CSS-Datei
├─ templates/ # HTML-Templates mit Tailwind-Klassen
├─ package.json # NPM-Konfiguration
├─ tailwind.config.js # Tailwind-Konfiguration
├─ postcss.config.js # PostCSS-Konfiguration
```
## Einrichtung
Das Projekt verwendet Tailwind CSS für das Frontend-Styling. Die Einrichtung wurde bereits abgeschlossen und umfasst:
1. **NPM-Abhängigkeiten** in der `package.json`
2. **Tailwind-Konfiguration** in `tailwind.config.js`
3. **PostCSS-Konfiguration** in `postcss.config.js`
4. **CSS-Eingabedatei** in `static/css/input.css`
5. **Generierte CSS-Datei** in `static/css/tailwind-dark-consolidated.min.css`
## Verwendung im Entwicklungsprozess
### CSS-Generierung
Um an den Styles zu arbeiten, verwenden Sie die folgenden Befehle:
1. **Abhängigkeiten installieren** (falls noch nicht geschehen):
```bash
npm install
```
2. **CSS überwachen und automatisch neu generieren**:
```bash
npm run watch:css
```
Dieser Befehl startet einen Watcher, der Änderungen an HTML-Templates und der input.css überwacht und automatisch die CSS-Datei neu generiert.
3. **CSS für Produktion erstellen**:
```bash
npm run build:css
```
Dieser Befehl erstellt eine minifizierte CSS-Datei für den Produktionseinsatz.
### Workflow
Der empfohlene Workflow für die Arbeit mit Tailwind CSS ist:
1. Starten Sie den Watcher mit `npm run watch:css`
2. Bearbeiten Sie die Template-Dateien in `templates/` oder fügen Sie eigene Komponenten in `static/css/input.css` hinzu
3. Die Änderungen werden automatisch in die generierte CSS-Datei übernommen
4. Führen Sie den Flask-Server mit `python3.11 app.py` aus, um die Änderungen zu sehen
## Dark Mode
Die Anwendung unterstützt einen Dark Mode. In den Templates wird dies folgendermaßen implementiert:
```html
<html class="light" data-theme="light">
<!-- oder für Dark Mode: -->
<html class="dark" data-theme="dark">
```
In Tailwind-Klassen verwenden Sie das `dark:` Präfix:
```html
<div class="bg-white text-gray-800 dark:bg-gray-800 dark:text-white">
Dieser Text passt sich dem Theme an
</div>
```
## Anpassungen
### Eigene Komponenten hinzufügen
Um eigene Komponenten zu definieren, verwenden Sie das `@layer components` Konstrukt in der `static/css/input.css` Datei:
```css
@layer components {
.custom-button {
@apply bg-indigo-600 text-white px-4 py-2 rounded-lg hover:bg-indigo-700;
}
}
```
### Tailwind-Konfiguration anpassen
Die Tailwind-Konfiguration wird in der `tailwind.config.js` Datei vorgenommen. Hier können Sie:
- Farben anpassen
- Eigene Abstände definieren
- Schriftarten konfigurieren
- Plugins hinzufügen
- Theme-Einstellungen vornehmen
## Optimierung für Produktion
Für die Produktionsumgebung sollte die CSS-Datei optimiert werden:
```bash
npm run build:css
```
Dies erstellt eine minifizierte Version der CSS-Datei mit PurgeCSS, das ungenutzte CSS-Klassen entfernt.
## Fehlerbehebung
### Problem: CSS wird nicht aktualisiert
1. Stellen Sie sicher, dass der Watcher läuft (`npm run watch:css`)
2. Überprüfen Sie, ob Ihre Änderungen in einem Pfad sind, der in `tailwind.config.js` unter `content` definiert ist
3. Leeren Sie den Browser-Cache (`Ctrl+F5`)
### Problem: Node-Module nicht gefunden
```bash
npm install
```
### Problem: Tailwind-Befehle funktionieren nicht
Verwenden Sie `npx` vor dem Befehl:
```bash
npx tailwindcss -i ./static/css/input.css -o ./static/css/tailwind-dark-consolidated.min.css --minify
```

```
## Best Practices
1. **Konsistenz**: Verwenden Sie die UI-Komponenten für einheitliches Design
2. **Accessibility**: Nutzen Sie `aria_label` und andere Accessibility-Attribute
3. **Performance**: Laden Sie JavaScript-Utilities nur bei Bedarf
4. **Responsive**: Alle Komponenten sind responsive-ready
5. **Dark Mode**: Alle Komponenten unterstützen automatisch Dark/Light Mode
## Troubleshooting
### Komponenten werden nicht angezeigt
- Prüfen Sie, ob `register_template_helpers(app)` in `init_app()` aufgerufen wird
- Stellen Sie sicher, dass Tailwind CSS kompiliert wurde
### JavaScript-Funktionen nicht verfügbar
- Laden Sie `ui-components.js` in Ihrem Template
- Prüfen Sie die Browser-Konsole auf Fehler
### Styling-Probleme
- Stellen Sie sicher, dass die CSS-Datei geladen wird
- Prüfen Sie, ob Custom-CSS die Komponenten überschreibt

# quick-lru [![Build Status](https://travis-ci.org/sindresorhus/quick-lru.svg?branch=master)](https://travis-ci.org/sindresorhus/quick-lru) [![Coverage Status](https://coveralls.io/repos/github/sindresorhus/quick-lru/badge.svg?branch=master)](https://coveralls.io/github/sindresorhus/quick-lru?branch=master)
> Simple [“Least Recently Used” (LRU) cache](https://en.m.wikipedia.org/wiki/Cache_replacement_policies#Least_Recently_Used_.28LRU.29)
Useful when you need to cache something and limit memory usage.
Inspired by the [`hashlru` algorithm](https://github.com/dominictarr/hashlru#algorithm), but instead uses [`Map`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Map) to support keys of any type, not just strings, and values can be `undefined`.
## Install
```
$ npm install quick-lru
```
## Usage
```js
const QuickLRU = require('quick-lru');
const lru = new QuickLRU({maxSize: 1000});
lru.set('🦄', '🌈');
lru.has('🦄');
//=> true
lru.get('🦄');
//=> '🌈'
```
## API
### new QuickLRU(options?)
Returns a new instance.
### options
Type: `object`
#### maxSize
*Required*\
Type: `number`
The maximum number of items before evicting the least recently used items.
#### maxAge
Type: `number`\
Default: `Infinity`
The maximum number of milliseconds an item should remain in cache.
By default maxAge will be Infinity, which means that items will never expire.
Lazy expiration happens upon the next `write` or `read` call.
Individual expiration of an item can be specified by the `set(key, value, options)` method.
#### onEviction
*Optional*\
Type: `(key, value) => void`
Called right before an item is evicted from the cache.
Useful for side effects or for items like object URLs that need explicit cleanup (`revokeObjectURL`).
### Instance
The instance is [`iterable`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Iteration_protocols) so you can use it directly in a [`for…of`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/for...of) loop.
Both `key` and `value` can be of any type.
#### .set(key, value, options?)
Set an item. Returns the instance.
Individual expiration of an item can be specified with the `maxAge` option. If not specified, the global `maxAge` value will be used in case it is specified on the constructor, otherwise the item will never expire.
#### .get(key)
Get an item.
#### .has(key)
Check if an item exists.
#### .peek(key)
Get an item without marking it as recently used.
#### .delete(key)
Delete an item.
Returns `true` if the item is removed or `false` if the item doesn't exist.
#### .clear()
Delete all items.
#### .resize(maxSize)
Update the `maxSize`, discarding items as necessary. Insertion order is mostly preserved, though this is not a strong guarantee.
Useful for on-the-fly tuning of cache sizes in live systems.
#### .keys()
Iterable for all the keys.
#### .values()
Iterable for all the values.
#### .entriesAscending()
Iterable for all entries, starting with the oldest (ascending in recency).
#### .entriesDescending()
Iterable for all entries, starting with the newest (descending in recency).
#### .size
The stored item count.

# @isaacs/cliui
Temporary fork of [cliui](http://npm.im/cliui).
![ci](https://github.com/yargs/cliui/workflows/ci/badge.svg)
[![NPM version](https://img.shields.io/npm/v/cliui.svg)](https://www.npmjs.com/package/cliui)
[![Conventional Commits](https://img.shields.io/badge/Conventional%20Commits-1.0.0-yellow.svg)](https://conventionalcommits.org)
![nycrc config on GitHub](https://img.shields.io/nycrc/yargs/cliui)
easily create complex multi-column command-line-interfaces.
## Example
```js
const ui = require('cliui')()
ui.div('Usage: $0 [command] [options]')
ui.div({
text: 'Options:',
padding: [2, 0, 1, 0]
})
ui.div(
{
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
},
{
text: "the file to load." +
chalk.green("(if this description is long it wraps).")
,
width: 20
},
{
text: chalk.red("[required]"),
align: 'right'
}
)
console.log(ui.toString())
```
## Deno/ESM Support
As of `v7` `cliui` supports [Deno](https://github.com/denoland/deno) and
[ESM](https://nodejs.org/api/esm.html#esm_ecmascript_modules):
```typescript
import cliui from "https://deno.land/x/cliui/deno.ts";
const ui = cliui({})
ui.div('Usage: $0 [command] [options]')
ui.div({
text: 'Options:',
padding: [2, 0, 1, 0]
})
ui.div({
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
})
console.log(ui.toString())
```
<img width="500" src="screenshot.png">
## Layout DSL
cliui exposes a simple layout DSL:
If you create a single `ui.div`, passing a string rather than an
object:
* `\n`: characters will be interpreted as new rows.
* `\t`: characters will be interpreted as new columns.
* `\s`: characters will be interpreted as padding.
**as an example...**
```js
var ui = require('./')({
width: 60
})
ui.div(
'Usage: node ./bin/foo.js\n' +
' <regex>\t provide a regex\n' +
' <glob>\t provide a glob\t [required]'
)
console.log(ui.toString())
```
**will output:**
```shell
Usage: node ./bin/foo.js
<regex> provide a regex
<glob> provide a glob [required]
```
## Methods
```js
cliui = require('cliui')
```
### cliui({width: integer})
Specify the maximum width of the UI being generated.
If no width is provided, cliui will try to get the current window's width and use it, and if that doesn't work, width will be set to `80`.
### cliui({wrap: boolean})
Enable or disable the wrapping of text in a column.
### cliui.div(column, column, column)
Create a row with any number of columns, a column
can either be a string, or an object with the following
options:
* **text:** some text to place in the column.
* **width:** the width of a column.
* **align:** alignment, `right` or `center`.
* **padding:** `[top, right, bottom, left]`.
* **border:** should a border be placed around the div?
### cliui.span(column, column, column)
Similar to `div`, except the next row will be appended without
a new line being created.
### cliui.resetOutput()
Resets the UI elements of the current cliui instance, maintaining the values
set for `width` and `wrap`.

# @jridgewell/gen-mapping
> Generate source maps
`gen-mapping` allows you to generate a source map during transpilation or minification.
With a source map, you're able to trace the original location in the source file, either in Chrome's
DevTools or using a library like [`@jridgewell/trace-mapping`][trace-mapping].
You may already be familiar with the [`source-map`][source-map] package's `SourceMapGenerator`. This
provides the same `addMapping` and `setSourceContent` API.
## Installation
```sh
npm install @jridgewell/gen-mapping
```
## Usage
```typescript
import { GenMapping, addMapping, setSourceContent, toEncodedMap, toDecodedMap } from '@jridgewell/gen-mapping';
const map = new GenMapping({
file: 'output.js',
sourceRoot: 'https://example.com/',
});
setSourceContent(map, 'input.js', `function foo() {}`);
addMapping(map, {
// Lines start at line 1, columns at column 0.
generated: { line: 1, column: 0 },
source: 'input.js',
original: { line: 1, column: 0 },
});
addMapping(map, {
generated: { line: 1, column: 9 },
source: 'input.js',
original: { line: 1, column: 9 },
name: 'foo',
});
assert.deepEqual(toDecodedMap(map), {
version: 3,
file: 'output.js',
names: ['foo'],
sourceRoot: 'https://example.com/',
sources: ['input.js'],
sourcesContent: ['function foo() {}'],
mappings: [
[ [0, 0, 0, 0], [9, 0, 0, 9, 0] ]
],
});
assert.deepEqual(toEncodedMap(map), {
version: 3,
file: 'output.js',
names: ['foo'],
sourceRoot: 'https://example.com/',
sources: ['input.js'],
sourcesContent: ['function foo() {}'],
mappings: 'AAAA,SAASA',
});
```
### Smaller Sourcemaps
Not everything needs to be added to a sourcemap, and needless markings can cause signficantly
larger file sizes. `gen-mapping` exposes `maybeAddSegment`/`maybeAddMapping` APIs that will
intelligently determine if this marking adds useful information. If not, the marking will be
skipped.
```typescript
import { maybeAddMapping } from '@jridgewell/gen-mapping';
const map = new GenMapping();
// Adding a sourceless marking at the beginning of a line isn't useful.
maybeAddMapping(map, {
generated: { line: 1, column: 0 },
});
// Adding a new source marking is useful.
maybeAddMapping(map, {
generated: { line: 1, column: 0 },
source: 'input.js',
original: { line: 1, column: 0 },
});
// But adding another marking pointing to the exact same original location isn't, even if the
// generated column changed.
maybeAddMapping(map, {
generated: { line: 1, column: 9 },
source: 'input.js',
original: { line: 1, column: 0 },
});
assert.deepEqual(toEncodedMap(map), {
version: 3,
names: [],
sources: ['input.js'],
sourcesContent: [null],
mappings: 'AAAA',
});
```

# @jridgewell/set-array
> Like a Set, but provides the index of the `key` in the backing array
This is designed to allow synchronizing a second array with the contents of the backing array, like
how in a sourcemap `sourcesContent[i]` is the source content associated with `source[i]`, and there
are never duplicates.
## Installation
```sh
npm install @jridgewell/set-array
```
## Usage
```js
import { SetArray, get, put, pop } from '@jridgewell/set-array';
const sa = new SetArray();
let index = put(sa, 'first');
assert.strictEqual(index, 0);
index = put(sa, 'second');
assert.strictEqual(index, 1);
assert.deepEqual(sa.array, [ 'first', 'second' ]);
index = get(sa, 'first');
assert.strictEqual(index, 0);
pop(sa);
index = get(sa, 'second');
assert.strictEqual(index, undefined);
assert.deepEqual(sa.array, [ 'first' ]);

# @jridgewell/sourcemap-codec
Encode/decode the `mappings` property of a [sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit).
## Why?
Sourcemaps are difficult to generate and manipulate, because the `mappings` property the part that actually links the generated code back to the original source is encoded using an obscure method called [Variable-length quantity](https://en.wikipedia.org/wiki/Variable-length_quantity). On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation you have to understand the whole sourcemap.
This package makes the process slightly easier.
## Installation
```bash
npm install @jridgewell/sourcemap-codec
```
## Usage
```js
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
assert.deepEqual( decoded, [
// the first line (of the generated code) has no mappings,
// as shown by the starting semi-colon (which separates lines)
[],
// the second line contains four (comma-separated) segments
[
// segments are encoded as you'd expect:
// [ generatedCodeColumn, sourceIndex, sourceCodeLine, sourceCodeColumn, nameIndex ]
// i.e. the first segment begins at column 2, and maps back to the second column
// of the second line (both zero-based) of the 0th source, and uses the 0th
// name in the `map.names` array
[ 2, 0, 2, 2, 0 ],
// the remaining segments are 4-length rather than 5-length,
// because they don't map a name
[ 4, 0, 2, 4 ],
[ 6, 0, 2, 5 ],
[ 7, 0, 2, 7 ]
],
// the final line contains two segments
[
[ 2, 1, 10, 19 ],
[ 12, 1, 11, 20 ]
]
]);
var encoded = encode( decoded );
assert.equal( encoded, ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
```

> Trace the original position through a source map
`trace-mapping` allows you to take the line and column of an output file and trace it to the
original location in the source file through a source map.
You may already be familiar with the [`source-map`][source-map] package's `SourceMapConsumer`. This
provides the same `originalPositionFor` and `generatedPositionFor` API, without requiring WASM.
## Installation
```sh
npm install @jridgewell/trace-mapping
```
## Usage
```typescript
import {
TraceMap,
originalPositionFor,
generatedPositionFor,
sourceContentFor,
isIgnored,
} from '@jridgewell/trace-mapping';
const tracer = new TraceMap({
version: 3,
sources: ['input.js'],
sourcesContent: ['content of input.js'],
names: ['foo'],
mappings: 'KAyCIA',
ignoreList: [],
});
// Lines start at line 1, columns at column 0.
const traced = originalPositionFor(tracer, { line: 1, column: 5 });
assert.deepEqual(traced, {
source: 'input.js',
line: 42,
column: 4,
name: 'foo',
});
const content = sourceContentFor(tracer, traced.source);
assert.strictEqual(content, 'content for input.js');
const generated = generatedPositionFor(tracer, {
source: 'input.js',
line: 42,
column: 4,
});
assert.deepEqual(generated, {
line: 1,
column: 5,
});
const ignored = isIgnored(tracer, 'input.js');
assert.equal(ignored, false);
```
We also provide a lower level API to get the actual segment that matches our line and column. Unlike
`originalPositionFor`, `traceSegment` uses a 0-base for `line`:
```typescript
import { traceSegment } from '@jridgewell/trace-mapping';
// line is 0-base.
const traced = traceSegment(tracer, /* line */ 0, /* column */ 5);
// Segments are [outputColumn, sourcesIndex, sourceLine, sourceColumn, namesIndex]
// Again, line is 0-base and so is sourceLine
assert.deepEqual(traced, [5, 0, 41, 4, 0]);
```
### SectionedSourceMaps
The sourcemap spec defines a special `sections` field that's designed to handle concatenation of
output code with associated sourcemaps. This type of sourcemap is rarely used (no major build tool
produces it), but if you are hand coding a concatenation you may need it. We provide an `AnyMap`
helper that can receive either a regular sourcemap or a `SectionedSourceMap` and returns a
`TraceMap` instance:
```typescript
import { AnyMap } from '@jridgewell/trace-mapping';
const fooOutput = 'foo';
const barOutput = 'bar';
const output = [fooOutput, barOutput].join('\n');
const sectioned = new AnyMap({
version: 3,
sections: [
{
// 0-base line and column
offset: { line: 0, column: 0 },
// fooOutput's sourcemap
map: {
version: 3,
sources: ['foo.js'],
names: ['foo'],
mappings: 'AAAAA',
},
},
{
// barOutput's sourcemap will not affect the first line, only the second
offset: { line: 1, column: 0 },
map: {
version: 3,
sources: ['bar.js'],
names: ['bar'],
mappings: 'AAAAA',
},
},
],
});
const traced = originalPositionFor(sectioned, {
line: 2,
column: 0,
});
assert.deepEqual(traced, {
source: 'bar.js',
line: 1,
column: 0,
name: 'bar',
});
```

# @nodelib/fs.scandir
> List files and directories inside the specified directory.
## :bulb: Highlights
The package is aimed at obtaining information about entries in the directory.
* :moneybag: Returns useful information: `name`, `path`, `dirent` and `stats` (optional).
* :gear: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type. See [`old` and `modern` mode](#old-and-modern-mode).
* :link: Can safely work with broken symbolic links.
## Install
```console
npm install @nodelib/fs.scandir
```
## Usage
```ts
import * as fsScandir from '@nodelib/fs.scandir';
fsScandir.scandir('path', (error, stats) => { /* … */ });
```
## API
### .scandir(path, [optionsOrSettings], callback)
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path with standard callback-style.
```ts
fsScandir.scandir('path', (error, entries) => { /* … */ });
fsScandir.scandir('path', {}, (error, entries) => { /* … */ });
fsScandir.scandir('path', new fsScandir.Settings(), (error, entries) => { /* … */ });
```
### .scandirSync(path, [optionsOrSettings])
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path.
```ts
const entries = fsScandir.scandirSync('path');
const entries = fsScandir.scandirSync('path', {});
const entries = fsScandir.scandirSync(('path', new fsScandir.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settingsoptions) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsScandir.Settings({ followSymbolicLinks: false });
const entries = fsScandir.scandirSync('path', settings);
```
## Entry
* `name` — The name of the entry (`unknown.txt`).
* `path` — The path of the entry relative to call directory (`root/unknown.txt`).
* `dirent` — An instance of [`fs.Dirent`](./src/types/index.ts) class. On Node.js below 10.10 will be emulated by [`DirentFromStats`](./src/utils/fs.ts) class.
* `stats` (optional) — An instance of `fs.Stats` class.
For example, the `scandir` call for `tools` directory with one directory inside:
```ts
{
dirent: Dirent { name: 'typedoc', /* … */ },
name: 'typedoc',
path: 'tools/typedoc'
}
```
## Options
### stats
* Type: `boolean`
* Default: `false`
Adds an instance of `fs.Stats` class to the [`Entry`](#entry).
> :book: Always use `fs.readdir` without the `withFileTypes` option. ??TODO??
### followSymbolicLinks
* Type: `boolean`
* Default: `false`
Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely use `lstat` call if `false`.
### `pathSegmentSeparator`
* Type: `string`
* Default: `path.sep`
By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat?: typeof fs.lstat;
stat?: typeof fs.stat;
lstatSync?: typeof fs.lstatSync;
statSync?: typeof fs.statSync;
readdir?: typeof fs.readdir;
readdirSync?: typeof fs.readdirSync;
}
const settings = new fsScandir.Settings({
fs: { lstat: fakeLstat }
});
```
## `old` and `modern` mode
This package has two modes that are used depending on the environment and parameters of use.
### old
* Node.js below `10.10` or when the `stats` option is enabled
When working in the old mode, the directory is read first (`fs.readdir`), then the type of entries is determined (`fs.lstat` and/or `fs.stat` for symbolic links).
### modern
* Node.js 10.10+ and the `stats` option is disabled
In the modern mode, reading the directory (`fs.readdir` with the `withFileTypes` option) is combined with obtaining information about its entries. An additional call for symbolic links (`fs.stat`) is still present.
This mode makes fewer calls to the file system. It's faster.

# @nodelib/fs.stat
> Get the status of a file with some features.
## :bulb: Highlights
Wrapper around standard method `fs.lstat` and `fs.stat` with some features.
* :beginner: Normally follows symbolic link.
* :gear: Can safely work with broken symbolic link.
## Install
```console
npm install @nodelib/fs.stat
```
## Usage
```ts
import * as fsStat from '@nodelib/fs.stat';
fsStat.stat('path', (error, stats) => { /* … */ });
```
## API
### .stat(path, [optionsOrSettings], callback)
Returns an instance of `fs.Stats` class for provided path with standard callback-style.
```ts
fsStat.stat('path', (error, stats) => { /* … */ });
fsStat.stat('path', {}, (error, stats) => { /* … */ });
fsStat.stat('path', new fsStat.Settings(), (error, stats) => { /* … */ });
```
### .statSync(path, [optionsOrSettings])
Returns an instance of `fs.Stats` class for provided path.
```ts
const stats = fsStat.stat('path');
const stats = fsStat.stat('path', {});
const stats = fsStat.stat('path', new fsStat.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings

* Default: `true`
Follow symbolic link or not. Call `fs.stat` on symbolic link if `true`.
### `markSymbolicLink`
* Type: `boolean`
* Default: `false`
Mark symbolic link by setting the return value of `isSymbolicLink` function to always `true` (even after `fs.stat`).
> :book: Can be used if you want to know what is hidden behind a symbolic link, but still continue to know that it is a symbolic link.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.

const settings = new fsStat.Settings({
fs: { lstat: fakeLstat }
});

# @nodelib/fs.walk
> A library for efficiently walking a directory recursively.
## :bulb: Highlights
* :moneybag: Returns useful information: `name`, `path`, `dirent` and `stats` (optional).
* :rocket: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type for performance reasons. See [`old` and `modern` mode](https://github.com/nodelib/nodelib/blob/master/packages/fs/fs.scandir/README.md#old-and-modern-mode).
* :gear: Built-in directories/files and error filtering system.
* :link: Can safely work with broken symbolic links.
## Install
```console
npm install @nodelib/fs.walk
```
## Usage
```ts
import * as fsWalk from '@nodelib/fs.walk';
fsWalk.walk('path', (error, entries) => { /* … */ });
```
## API
### .walk(path, [optionsOrSettings], callback)
Reads the directory recursively and asynchronously. Requires a callback function.
> :book: If you want to use the Promise API, use `util.promisify`.
```ts
fsWalk.walk('path', (error, entries) => { /* … */ });
fsWalk.walk('path', {}, (error, entries) => { /* … */ });
fsWalk.walk('path', new fsWalk.Settings(), (error, entries) => { /* … */ });
```
### .walkStream(path, [optionsOrSettings])
Reads the directory recursively and asynchronously. [Readable Stream](https://nodejs.org/dist/latest-v12.x/docs/api/stream.html#stream_readable_streams) is used as a provider.
```ts
const stream = fsWalk.walkStream('path');
const stream = fsWalk.walkStream('path', {});
const stream = fsWalk.walkStream('path', new fsWalk.Settings());
```
### .walkSync(path, [optionsOrSettings])
Reads the directory recursively and synchronously. Returns an array of entries.
```ts
const entries = fsWalk.walkSync('path');
const entries = fsWalk.walkSync('path', {});
const entries = fsWalk.walkSync('path', new fsWalk.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settings) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsWalk.Settings({ followSymbolicLinks: true });
const entries = fsWalk.walkSync('path', settings);
```
## Entry
* `name` — The name of the entry (`unknown.txt`).
* `path` — The path of the entry relative to call directory (`root/unknown.txt`).
* `dirent` — An instance of [`fs.Dirent`](./src/types/index.ts) class.
* [`stats`] — An instance of `fs.Stats` class.
## Options
### basePath
* Type: `string`
* Default: `undefined`
By default, all paths are built relative to the root path. You can use this option to set custom root path.
In the example below we read the files from the `root` directory, but in the results the root path will be `custom`.
```ts
fsWalk.walkSync('root'); // → ['root/file.txt']
fsWalk.walkSync('root', { basePath: 'custom' }); // → ['custom/file.txt']
```
### concurrency
* Type: `number`
* Default: `Infinity`
The maximum number of concurrent calls to `fs.readdir`.
> :book: The higher the number, the higher performance and the load on the File System. If you want to read in quiet mode, set the value to `4 * os.cpus().length` (4 is default size of [thread pool work scheduling](http://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling)).
### deepFilter
* Type: [`DeepFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that indicates whether the directory will be read deep or not.
```ts
// Skip all directories that starts with `node_modules`
const filter: DeepFilterFunction = (entry) => !entry.path.startsWith('node_modules');
```
### entryFilter
* Type: [`EntryFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that indicates whether the entry will be included to results or not.
```ts
// Exclude all `.js` files from results
const filter: EntryFilterFunction = (entry) => !entry.name.endsWith('.js');
```
### errorFilter
* Type: [`ErrorFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that allows you to skip errors that occur when reading directories.
For example, you can skip `ENOENT` errors if required:
```ts
// Skip all ENOENT errors
const filter: ErrorFilterFunction = (error) => error.code == 'ENOENT';
```
### stats
* Type: `boolean`
* Default: `false`
Adds an instance of `fs.Stats` class to the [`Entry`](#entry).
> :book: Always use `fs.readdir` with additional `fs.lstat/fs.stat` calls to determine the entry type.
### followSymbolicLinks
* Type: `boolean`
* Default: `false`
Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`.
### `pathSegmentSeparator`
* Type: `string`
* Default: `path.sep`
By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.
### `fs`
* Type: `FileSystemAdapter`
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat: typeof fs.lstat;
stat: typeof fs.stat;
lstatSync: typeof fs.lstatSync;
statSync: typeof fs.statSync;
readdir: typeof fs.readdir;
readdirSync: typeof fs.readdirSync;
}
const settings = new fsWalk.Settings({
fs: { lstat: fakeLstat }
});
```

# parseArgs
[![Coverage][coverage-image]][coverage-url]
Polyfill of `util.parseArgs()`
## `util.parseArgs([config])`
<!-- YAML
added: v18.3.0
changes:
- version: REPLACEME
pr-url: https://github.com/nodejs/node/pull/43459
description: add support for returning detailed parse information
using `tokens` in input `config` and returned properties.
-->
> Stability: 1 - Experimental
* `config` {Object} Used to provide arguments for parsing and to configure
the parser. `config` supports the following properties:
* `args` {string\[]} array of argument strings. **Default:** `process.argv`
with `execPath` and `filename` removed.
* `options` {Object} Used to describe arguments known to the parser.
Keys of `options` are the long names of options and values are an
{Object} accepting the following properties:
* `type` {string} Type of argument, which must be either `boolean` or `string`.
* `multiple` {boolean} Whether this option can be provided multiple
times. If `true`, all values will be collected in an array. If
`false`, values for the option are last-wins. **Default:** `false`.
* `short` {string} A single character alias for the option.
* `default` {string | boolean | string\[] | boolean\[]} The default option
value when it is not set by args. It must be of the same type as the
the `type` property. When `multiple` is `true`, it must be an array.
* `strict` {boolean} Should an error be thrown when unknown arguments
are encountered, or when arguments are passed that do not match the
`type` configured in `options`.
**Default:** `true`.
* `allowPositionals` {boolean} Whether this command accepts positional
arguments.
**Default:** `false` if `strict` is `true`, otherwise `true`.
* `tokens` {boolean} Return the parsed tokens. This is useful for extending
the built-in behavior, from adding additional checks through to reprocessing
the tokens in different ways.
**Default:** `false`.
* Returns: {Object} The parsed command line arguments:
* `values` {Object} A mapping of parsed option names with their {string}
or {boolean} values.
* `positionals` {string\[]} Positional arguments.
* `tokens` {Object\[] | undefined} See [parseArgs tokens](#parseargs-tokens)
section. Only returned if `config` includes `tokens: true`.
Provides a higher level API for command-line argument parsing than interacting
with `process.argv` directly. Takes a specification for the expected arguments
and returns a structured object with the parsed options and positionals.
```mjs
import { parseArgs } from 'node:util';
const args = ['-f', '--bar', 'b'];
const options = {
foo: {
type: 'boolean',
short: 'f'
},
bar: {
type: 'string'
}
};
const {
values,
positionals
} = parseArgs({ args, options });
console.log(values, positionals);
// Prints: [Object: null prototype] { foo: true, bar: 'b' } []
```
```cjs
const { parseArgs } = require('node:util');
const args = ['-f', '--bar', 'b'];
const options = {
foo: {
type: 'boolean',
short: 'f'
},
bar: {
type: 'string'
}
};
const {
values,
positionals
} = parseArgs({ args, options });
console.log(values, positionals);
// Prints: [Object: null prototype] { foo: true, bar: 'b' } []
```
`util.parseArgs` is experimental and behavior may change. Join the
conversation in [pkgjs/parseargs][] to contribute to the design.
### `parseArgs` `tokens`
Detailed parse information is available for adding custom behaviours by
specifying `tokens: true` in the configuration.
The returned tokens have properties describing:
* all tokens
* `kind` {string} One of 'option', 'positional', or 'option-terminator'.
* `index` {number} Index of element in `args` containing token. So the
source argument for a token is `args[token.index]`.
* option tokens
* `name` {string} Long name of option.
* `rawName` {string} How option used in args, like `-f` of `--foo`.
* `value` {string | undefined} Option value specified in args.
Undefined for boolean options.
* `inlineValue` {boolean | undefined} Whether option value specified inline,
like `--foo=bar`.
* positional tokens
* `value` {string} The value of the positional argument in args (i.e. `args[index]`).
* option-terminator token
The returned tokens are in the order encountered in the input args. Options
that appear more than once in args produce a token for each use. Short option
groups like `-xy` expand to a token for each option. So `-xxx` produces
three tokens.
For example to use the returned tokens to add support for a negated option
like `--no-color`, the tokens can be reprocessed to change the value stored
for the negated option.
```mjs
import { parseArgs } from 'node:util';
const options = {
'color': { type: 'boolean' },
'no-color': { type: 'boolean' },
'logfile': { type: 'string' },
'no-logfile': { type: 'boolean' },
};
const { values, tokens } = parseArgs({ options, tokens: true });
// Reprocess the option tokens and overwrite the returned values.
tokens
.filter((token) => token.kind === 'option')
.forEach((token) => {
if (token.name.startsWith('no-')) {
// Store foo:false for --no-foo
const positiveName = token.name.slice(3);
values[positiveName] = false;
delete values[token.name];
} else {
// Resave value so last one wins if both --foo and --no-foo.
values[token.name] = token.value ?? true;
}
});
const color = values.color;
const logfile = values.logfile ?? 'default.log';
console.log({ logfile, color });
```
```cjs
const { parseArgs } = require('node:util');
const options = {
'color': { type: 'boolean' },
'no-color': { type: 'boolean' },
'logfile': { type: 'string' },
'no-logfile': { type: 'boolean' },
};
const { values, tokens } = parseArgs({ options, tokens: true });
// Reprocess the option tokens and overwrite the returned values.
tokens
.filter((token) => token.kind === 'option')
.forEach((token) => {
if (token.name.startsWith('no-')) {
// Store foo:false for --no-foo
const positiveName = token.name.slice(3);
values[positiveName] = false;
delete values[token.name];
} else {
// Resave value so last one wins if both --foo and --no-foo.
values[token.name] = token.value ?? true;
}
});
const color = values.color;
const logfile = values.logfile ?? 'default.log';
console.log({ logfile, color });
```
Example usage showing negated options, and when an option is used
multiple ways then last one wins.
```console
$ node negate.js
{ logfile: 'default.log', color: undefined }
$ node negate.js --no-logfile --no-color
{ logfile: false, color: false }
$ node negate.js --logfile=test.log --color
{ logfile: 'test.log', color: true }
$ node negate.js --no-logfile --logfile=test.log --color --no-color
{ logfile: 'test.log', color: false }
```

## Scope
It is already possible to build great arg parsing modules on top of what Node.js provides; the prickly API is abstracted away by these modules. Thus, process.parseArgs() is not necessarily intended for library authors; it is intended for developers of simple CLI tools, ad-hoc scripts, deployed Node.js applications, and learning materials.
It is exceedingly difficult to provide an API which would both be friendly to these Node.js users while being extensible enough for libraries to build upon. We chose to prioritize these use cases because these are currently not well-served by Node.js' API.

----
## 🚀 Getting Started
1. **Install dependencies.**
```bash
npm install
```
2. **Open the index.js file and start editing!**
3. **Test your code by calling parseArgs through our test file**
```bash
npm test
```

## 🙌 Contributing
Any person who wants to contribute to the initiative is welcome! Please first read the [Contributing Guide](CONTRIBUTING.md)
Additionally, reading the [`Examples w/ Output`](#-examples-w-output) section of this document will be the best way to familiarize yourself with the target expected behavior for parseArgs() once it is fully implemented.
This package was implemented using [tape](https://www.npmjs.com/package/tape) as its test harness.

## 💡 `process.mainArgs` Proposal
> Note: This can be moved forward independently of the `util.parseArgs()` proposal/work.
### Implementation:
```javascript
process.mainArgs = process.argv.slice(process._exec ? 1 : 2)
```
----
## 📃 Examples
```js
const { parseArgs } = require('@pkgjs/parseargs');
```
```js
const { parseArgs } = require('@pkgjs/parseargs');
// specify the options that may be used
const options = {
foo: { type: 'string'},
bar: { type: 'boolean' },
};
const args = ['--foo=a', '--bar'];
const { values, positionals } = parseArgs({ args, options });
// values = { foo: 'a', bar: true }
// positionals = []
```
```js
const { parseArgs } = require('@pkgjs/parseargs');
// type:string & multiple
const options = {
foo: {
type: 'string',
multiple: true,
},
};
const args = ['--foo=a', '--foo', 'b'];
const { values, positionals } = parseArgs({ args, options });
// values = { foo: [ 'a', 'b' ] }
// positionals = []
```
```js
const { parseArgs } = require('@pkgjs/parseargs');
// shorts
const options = {
foo: {
short: 'f',
type: 'boolean'
},
};
const args = ['-f', 'b'];
const { values, positionals } = parseArgs({ args, options, allowPositionals: true });
// values = { foo: true }
// positionals = ['b']
```
```js
const { parseArgs } = require('@pkgjs/parseargs');
// unconfigured
const options = {};
const args = ['-f', '--foo=a', '--bar', 'b'];
const { values, positionals } = parseArgs({ strict: false, args, options, allowPositionals: true });
// values = { f: true, foo: 'a', bar: true }
// positionals = ['b']
```
----
## F.A.Qs
- Is `cmd --foo=bar baz` the same as `cmd baz --foo=bar`?
- yes
- Does the parser execute a function?
- no
- Does the parser execute one of several functions, depending on input?
- no
- Can subcommands take options that are distinct from the main command?
- no
- Does it output generated help when no options match?
- no
- Does it generated short usage? Like: `usage: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [file ...]`
- no (no usage/help at all)
- Does the user provide the long usage text? For each option? For the whole command?
- no
- Do subcommands (if implemented) have their own usage output?
- no
- Does usage print if the user runs `cmd --help`?
- no
- Does it set `process.exitCode`?
- no
- Does usage print to stderr or stdout?
- N/A
- Does it check types? (Say, specify that an option is a boolean, number, etc.)
- no
- Can an option have more than one type? (string or false, for example)
- no
- Can the user define a type? (Say, `type: path` to call `path.resolve()` on the argument.)
- no
- Does a `--foo=0o22` mean 0, 22, 18, or "0o22"?
- `"0o22"`
- Does it coerce types?
- no
- Does `--no-foo` coerce to `--foo=false`? For all options? Only boolean options?
- no, it sets `{values:{'no-foo': true}}`
- Is `--foo` the same as `--foo=true`? Only for known booleans? Only at the end?
- no, they are not the same. There is no special handling of `true` as a value so it is just another string.
- Does it read environment variables? Ie, is `FOO=1 cmd` the same as `cmd --foo=1`?
- no
- Do unknown arguments raise an error? Are they parsed? Are they treated as positional arguments?
- no, they are parsed, not treated as positionals
- Does `--` signal the end of options?
- yes
- Is `--` included as a positional?
- no
- Is `program -- foo` the same as `program foo`?
- yes, both store `{positionals:['foo']}`
- Does the API specify whether a `--` was present/relevant?
- no
- Is `-bar` the same as `--bar`?
- no, `-bar` is a short option or options, with expansion logic that follows the
[Utility Syntax Guidelines in POSIX.1-2017](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap12.html). `-bar` expands to `-b`, `-a`, `-r`.
- Is `---foo` the same as `--foo`?
- no
- the first is a long option named `'-foo'`
- the second is a long option named `'foo'`
- Is `-` a positional? ie, `bash some-test.sh | tap -`
- yes

## API
### ansiRegex(options?)
Returns a regex for matching ANSI escape codes.
#### options
Type: `object`
##### onlyFirst
Type: `boolean`\
Default: `false` *(Matches any ANSI escape codes in a string)*
Match only the first ANSI escape.
## FAQ
### Why do you test for codes not in the ECMA 48 standard?
Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

# ansi-styles
> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
![](screenshot.png)
## Install
```sh
npm install ansi-styles
```
## Usage
```js
import styles from 'ansi-styles';
console.log(`${styles.green.open}Hello world!${styles.green.close}`);
// Color conversion between 256/truecolor
// NOTE: When converting from truecolor to 256 colors, the original color
// may be degraded to fit the new color palette. This means terminals
// that do not support 16 million colors will best-match the
// original color.
console.log(`${styles.color.ansi(styles.rgbToAnsi(199, 20, 250))}Hello World${styles.color.close}`)
console.log(`${styles.color.ansi256(styles.rgbToAnsi256(199, 20, 250))}Hello World${styles.color.close}`)
console.log(`${styles.color.ansi16m(...styles.hexToRgb('#abcdef'))}Hello World${styles.color.close}`)
```
## API
### `open` and `close`
Each style has an `open` and `close` property.
### `modifierNames`, `foregroundColorNames`, `backgroundColorNames`, and `colorNames`
All supported style strings are exposed as an array of strings for convenience. `colorNames` is the combination of `foregroundColorNames` and `backgroundColorNames`.
This can be useful if you need to validate input:
```js
import {modifierNames, foregroundColorNames} from 'ansi-styles';
console.log(modifierNames.includes('bold'));
//=> true
console.log(foregroundColorNames.includes('pink'));
//=> false
```
## Styles
### Modifiers
- `reset`
- `bold`
- `dim`
- `italic` *(Not widely supported)*
- `underline`
- `overline` *Supported on VTE-based terminals, the GNOME terminal, mintty, and Git Bash.*
- `inverse`
- `hidden`
- `strikethrough` *(Not widely supported)*
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `blackBright` (alias: `gray`, `grey`)
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`
- `cyanBright`
- `whiteBright`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
- `bgRedBright`
- `bgGreenBright`
- `bgYellowBright`
- `bgBlueBright`
- `bgMagentaBright`
- `bgCyanBright`
- `bgWhiteBright`
## Advanced usage
By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
- `styles.modifier`
- `styles.color`
- `styles.bgColor`
###### Example
```js
import styles from 'ansi-styles';
console.log(styles.color.green.open);
```
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `styles.codes`, which returns a `Map` with the open codes as keys and close codes as values.
###### Example
```js
import styles from 'ansi-styles';
console.log(styles.codes.get(36));
//=> 39
```
## 16 / 256 / 16 million (TrueColor) support
`ansi-styles` allows converting between various color formats and ANSI escapes, with support for 16, 256 and [16 million colors](https://gist.github.com/XVilka/8346728).
The following color spaces are supported:
- `rgb`
- `hex`
- `ansi256`
- `ansi`
To use these, call the associated conversion function with the intended output, for example:
```js
import styles from 'ansi-styles';
styles.color.ansi(styles.rgbToAnsi(100, 200, 15)); // RGB to 16 color ansi foreground code
styles.bgColor.ansi(styles.hexToAnsi('#C0FFEE')); // HEX to 16 color ansi foreground code
styles.color.ansi256(styles.rgbToAnsi256(100, 200, 15)); // RGB to 256 color ansi foreground code
styles.bgColor.ansi256(styles.hexToAnsi256('#C0FFEE')); // HEX to 256 color ansi foreground code
styles.color.ansi16m(100, 200, 15); // RGB to 16 million color foreground code
styles.bgColor.ansi16m(...styles.hexToRgb('#C0FFEE')); // Hex (RGB) to 16 million color foreground code
```
