Installation

phil/highlight

Requirements

Requirement	Why
PHP 8.5 or later	Readonly classes, typed constants, `array_find()` and `array_any()`

The library has no other dependency, not even an extension beyond PHP's core.

Installing

composer require phil/highlight

It is a library, not a bundle: there is nothing to register. Build a Highlighter where code is shown, once, and keep it: Highlighter::default() builds every tokenizer, which is cheap, and none holds state between two sources.

The themes

The HTML holds classes only; a theme colours them. Three ship in themes/:

File	Colours
`themes/light.css`	For a light background
`themes/dark.css`	For a dark background
`themes/auto.css`	Light or dark as the system prefers, unless an ancestor carries `data-theme="light"` or `data-theme="dark"`

Serve the one you want from vendor/phil/highlight/themes/, copy it into the application's assets, or write your own (html-and-themes.md). phil/ux-bundle's stylesheet colours the same classes with its own colour roles: an application that loads it needs no theme from here.
