# TARTRAZINE
|
|
|
|
Tartrazine is a library to syntax-highlight code. It is
|
|
a port of [Pygments](https://pygments.org/) to
|
|
[Crystal](https://crystal-lang.org/). Kind of.
|
|
|
|
The CLI tool can be used to highlight many things in many styles.
|
|
|
|
# A port of what? Why "kind of"?
|
|
|
|
Pygments is a staple of the Python ecosystem, and it's great.
|
|
It lets you highlight code in many languages, and it has many
|
|
themes. Chroma is "Pygments for Go", it's actually a port of
|
|
Pygments to Go, and it's great too.
|
|
|
|
I wanted that in Crystal, so I started this project. But I did
|
|
not read much of the Pygments code. Or much of Chroma's.
|
|
|
|
Chroma has taken most of the Pygments lexers and turned them into
|
|
XML descriptions. What I did was take those XML files from Chroma
|
|
and a pile of test cases from Pygments, and I slapped them together
|
|
until the tests passed and my code produced the same output as
|
|
Chroma. Think of it as *extreme TDD*.
|
|
|
|
Currently the pass rate for tests in the supported languages
|
|
is `96.8%`, which is *not bad for a couple days hacking*.
|
|
|
|
This only covers the RegexLexers, which are the most common ones,
|
|
but it means the supported languages are a subset of Chroma's, which
|
|
is a subset of Pygments'.
|
|
|
|
Currently Tartrazine supports ... 241 languages.
|
|
|
|
It has 331 themes (63 from Chroma, the rest are base16 themes via

## Installation
|
|
|
|
From prebuilt binaries:
|
|
|
|
Each release provides statically-linked binaries that should
|
|
work on any Linux. Get them from the [releases page](https://github.com/ralsina/tartrazine/releases) and put them in your PATH.
|
|
|
|
To build from source:
|
|
|
|
1. Clone this repo
|
|
2. Run `make` to build the `tartrazine` binary
|
|
3. Copy the binary somewhere in your PATH.
|
|
|
|
## Usage
|
|
|
|
This works:
|
|
|
|
```crystal
|
|
require "tartrazine"
|
|
|
|
lexer = Tartrazine.lexer("crystal")
|
|
theme = Tartrazine.theme("catppuccin-macchiato")
|
|
puts Tartrazine::Html.new.format(File.read(ARGV[0]), lexer, theme)
|
|
```
