This commit introduces REUSE compliance by annotating all files with SPDX information and placing the reused licences in the LICENSES folder. We additionally removed the docheader tool which is made obsolete by this change. The main LICENSE and copyright text of the project is now not under my personal name anymore, and it belongs to "The Respect Project Contributors" instead. This change restores author names to several files, giving the appropriate attribution for contributions.

# Xdigit
|
|
|
|
- `Xdigit()`
|
|
- `Xdigit(string ...$additionalChars)`
|
|
|
|
Validates whether the input is an hexadecimal number or not.
|
|
|
|
```php
|
|
v::xdigit()->assert('abc123');
|
|
// Validation passes successfully
|
|
```
|
|
|
|
Notice, however, that it doesn't accept strings starting with 0x:
|
|
|
|
```php
|
|
v::xdigit()->assert('0x1f');
|
|
// → "0x1f" must only contain hexadecimal digits
|
|
```
|
|
|
