they told me i could become anything so i became an IR for snippet files

Why

Imagine you're using both the OLS (Obsidian LaTeX suite) in Obsidian and UltiSnips in NeoVim quite often. Sometimes, when typing longer LaTeX documents in Neovim, you notice that it'd be insanely neat to have the exact same snippets you're used to from taking notes in Obsidian anyway also in larger documents.

This program partly solves that by converting between the snippet files of OLS and UltiSnips at will.

Installation

Assumed you have Rust already installed (if not, see The Book) and you're not running an exotic platform, this is as simple as:

cargo install --git https://github.com/MultisampledNight/snippets-everywhere

Usage

Give --{ultisnips,ols}-in an input path, and --{ultisnips,ols}-out a corresponding output path.

snippets-everywhere --ultisnips-in in-file.snippets --ols-out out-file.json
snippets-everywhere --ols-in in-file.json --ultisnips-out out-file.snippets

Do note that --ols-in expects the input JSON file to be the one you see in the settings of OLS. Which you can get partly programmatically using this very sane construct...

python -c 'import json, pathlib; print(json.loads(pathlib.Path("$YOUR_VAULT_PATH/.obsidian/plugins/obsidian-latex-suite/data.json").expanduser().read_text()["snippets"]))'

...and replacing $YOUR_VAULT_PATH with your real vault path.

Caveats

• The UltiSnips snippet parser as triggered through using --ultisnips-in tries to replicate the parsing of UltiSnips itself as closely as reasonably possible. This also includes the same surprising behaviors: "wow" as trigger is parsed as "wow", unquoted, but "wow more" is parsed as wow more, quoted.
• Parsing and following extends directives in the UltiSnips parser isn't implemented. Would be easy to add, though.
• Comments are not preserved, and not even parsed by the input backends, just skipped.
• The OLS output is very condensed, and not pretty printed. If you want or need pretty printing, you can throw it through python -m json.tool.

FAQ

• An... IR?

  Yeah, I structured this a bit like I'd do in a compiler. It's more of a meme than anything serious, though.

• Can this take input and output on stdin and stdout instead of writing to files?

  On Unixalikes, you can just use /dev/stdin and /dev/stdout, respectively. I'm not sure about other platforms.

• Could other backends be added as well? How does the backend system even work?

  Open an issue describing where to find the format you want to parse and other details! I might implement it, I might not. Either way, if you know Rust (or want to learn it, check out The Book) see the module doccomment in src/backends/mod.rs!
