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.

:construction: Still under active development, feel free to open issues.

See the demo site

:sparkles: Features

Parses source to a list of interchangable data for further use

See the demo site's DEBUG panel.

Supported sources

UltiSnips

1. Positional placholder (aka 'TabStop' in UltiSnips)

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
