vscode-oniguruma VS codehike

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.

More specifically, we’re using [vscode-oniguruma](https://github.com/microsoft/vscode-oniguruma), which is made by Microsoft. But this introduced yet another problem: Integrating TextMate into Monaco typically requires hacks of some kind, and introduces some flaws into the experience.

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.
