What is shikiphp?
-----------------

[](#what-is-shikiphp)

shikiphp is a pure PHP port of [Shiki](https://shiki.style), the syntax highlighter that powers VS Code's own coloring. It tokenizes code with the same **TextMate grammars** and paints it with the same **VS Code themes** Shiki uses, producing identical HTML — entirely in PHP.

**The problem:** server-rendered syntax highlighting in PHP usually means either shelling out to Node, calling a hosted API, or settling for a regex-based highlighter that doesn't understand the language. None of those are great for a Laravel/WordPress/static-site build step.

**shikiphp solves this** by porting Shiki's real pipeline to PHP:

- TextMate grammar tokenizer (a faithful port of `vscode-textmate`), incl. embedded languages, injections, and nested repositories
- VS Code theme resolution with scope-selector specificity (`vscode-textmate`'s theme matching)
- A pure-PHP **JavaScript regex engine** as the grammar regex runtime, fed by an `oniguruma-to-es` port — the same Oniguruma→RegExp path modern Shiki uses
- Shiki-compatible HTML output: dual light/dark themes via CSS variables, `codeToHast`, transformers (all hooks), decorations, `colorReplacements`, `structure: inline`, and ANSI (`lang: 'ansi'`) highlighting
- the **full Shiki bundle** — every `tm-grammars` language (200+) and `tm-themes` theme (65)
- No PHP extensions beyond `json`/`mbstring`, no Node, no native Oniguruma binding
- Validated token-for-token against Shiki.js with an oracle regression harness (scenarios across the full grammar/theme set)
