Unisips

Unisnips is a set of tools to parse and generate expandable snippets, aiming to be the bridge between different editor/plugin/code-exapand-apps. It parses snippet sources (so far only a subset of UltiSnips is supported) and converts them to different targets.

You can keep only one set of expressive code templates - AKA snippets - and free yourself the chore of rewriting snippets to fit specifications of different platforms.

🚧 Still under active development, feel free to open issues.

✨ Features

Parses source to a list of interchangable data for further use

Example

unisnips convert --target vscode -i ~/.vim/Ultisnips/typescript.snippets -o ~/vscodesnippets/typescript.json

Roadmaps

• [x] Port a subset of UltiSnips parser to TypeScript, enable some basic and mostly used features

• [x] Add more builtin variables, may be useful in some targets (such as vscode's $CURRENT_YEAR)

• [ ] Parses transformers and convert them to vscode
