Why (not pygments)

I want html code snippets that look like my text editor.

For some languages, pygments (or highlight.js) is kinda bland:

Sublime & VS Code have so much more detail! Why? They use more complex parsing grammars than pygments does. Compare the ~70 line rule set that pygments uses for JavaScript with this fatty 1500 line grammar in Sublime. These grammars allow for more sophisticated styling in color schemes.

Now this example is a bit contrived. JavaScript is usually the worst offender with pygments, and not all themes even take advantage of the extra information Sublime provides. But generally, I think the added detail makes a difference in visually parsing text.

To scratch my own itch, I wanted something that:

looked like what I see in Sublime / VS Code / Github
had some good defaults out of the box
could fit into some sort of workflow

How to use

I thought about a few ways I might use this and broke it into some workflows:

• Get the css once, then highlight individual snippets:

1- Get the css

paint css "github" >> main.css

2- Get highlighted html, paste somewhere in <body>

# Get contents of whole file, or parts with --selection=X-Y
paint ./file.xx --html-only | clip

# Or, copy the text you want to add to a page:
paste | paint --filetype="xx" --html-only | clip

Piping into clip (or pbcopy or xclip) is the bees knees.

• Automatically highlight all code blocks within a document:

paint replace ./raw.html > highlighted.html

# also with watch mode, will re-highlight on file save
paint replace --watch ./raw.html --out highlighted.html

Looks for <pre data-paint="xx"></pre> blocks within a document and highlights everything inside them, where xx is the filetype to use (like using code fences in markdown: ```rust). Add other data attributes to enable other settings.

👉 Example

• Package everything into a script, embed like a gist:

Emulates the functionality of github gists. Outputs a small script that you can load from another page. Could be useful to keep a page clean from the noisy markup of highlighted examples.

paint ./file.xx --embed > example.js

<div class="embedded">
    <script src="./example.js"></script>
</div>

Install

Grab precompiled binaries from the latest release or install from source:

cargo install paint

Notes:

On windows you'll need to run vcvarsall.bat x64 first in order to compile syntect.
My vcvarsall (VS2015) was at: \Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat
