+$ npm install --save posix-character-classes
+```
+
+Install with [yarn](https://yarnpkg.com):
+
+```sh

+
+## POSIX Character classes
+
+The POSIX standard supports the following classes or categories of charactersh (note that classes must be defined within brackets)<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>:
+
+| **POSIX class** | **Equivalent to** | **Matches** | 
+| --- | --- | --- |
+| `[:alnum:]` | `[A-Za-z0-9]` | digits, uppercase and lowercase letters |
+| `[:alpha:]` | `[A-Za-z]` | upper- and lowercase letters |
+| `[:ascii:]` | `[\x00-\x7F]` | ASCII characters |
+| `[:blank:]` | `[ \t]` | space and TAB characters only |
+| `[:cntrl:]` | `[\x00-\x1F\x7F]` | Control characters |
+| `[:digit:]` | `[0-9]` | digits |
+| `[:graph:]` | `[^[:cntrl:]]` | graphic characters (all characters which have graphic representation) |
+| `[:lower:]` | `[a-z]` | lowercase letters |
+| `[:print:]` | `[[:graph] ]` | graphic characters and space |
+| `[:punct:]` | ``[-!"#$%&'()*+,./:;<=>?@[]^_`{ | }~]`` | all punctuation characters (all graphic characters except letters and digits) |
+| `[:space:]` | `[ \t\n\r\f\v]` | all blank (whitespace) characters, including spaces, tabs, new lines, carriage returns, form feeds, and vertical tabs |
+| `[:upper:]` | `[A-Z]` | uppercase letters |
+| `[:word:]` | `[A-Za-z0-9_]` | word characters |
+| `[:xdigit:]` | `[0-9A-Fa-f]` | hexadecimal digits |
+
+## Examples
+
+* `a[[:digit:]]b` matches `a0b`, `a1b`, ..., `a9b`.
+* `a[:digit:]b` is invalid, character classes must be enclosed in brackets
+* `[[:digit:]abc]` matches any digit, as well as `a`, `b`, and `c`.
+* `[abc[:digit:]]` is the same as the previous, matching any digit, as well as `a`, `b`, and `c`
+* `[^ABZ[:lower:]]` matches any character except lowercase letters, `A`, `B`, and `Z`.
