lighter VS vscode-textmate

Warning: This article refers to versions of Code Hike before 0.8.0. Since version 0.8.0, Code Hike uses lighter instead of Shiki. The approach presented in this article uses shiki's color replacement method, which no longer works with lighter.

Luckily, there is a project that has fitted my needs perfectly: vscode-grammar-test. It’s a command line tool that builds on the VS Code regex engine and grammar file parser and allows to run unit tests directly against a given grammar file.

Shiki does this because the underlying library vscode-textmate or vscode-oniguruma returns black if the value is not a valid color. This explains why Code Hike uses blackish color codes instead of variables. But what if we write a variable directly into the theme instead of the color code.

Thank you for the response! I feared that I might have to create a vscode extension for the language. I'm assuming I can use this json file to build textmate grammar for Stks ? Do you suggest any specific resources for learning textmate grammar and regex? I'm especially unfamiliar with regex. Thanks again

I see now. Thanks for the hint!

There are lots of different approaches you could take. For sourcecodeshots, I run it through VSCode's tokenizer (https://github.com/microsoft/vscode-textmate) and then use node-canvas to generate the image one line at a time.

It's a very imperative process and fairly slow on a cpu, but the nice thing is that I can run the same code in the browser to speed up development. The Rust project, https://github.com/Aloxaf/silicon, mentioned in another part of the comments is probably faster, but I didn't find it when I was searching for a solution.
