snippet-converter.nvim VS luacheck

Afaik there is nothing built into Neovim that can do this. However, I have required this for one of my plugins so I created it. Here is the link: https://github.com/smjonas/snippet-converter.nvim/blob/main/lua/snippet_converter/utils/json_utils.lua. Feel free to use it!

Also, my snipmate parser is probably a good starting point since the grammar is relatively simple: https://github.com/smjonas/snippet-converter.nvim/blob/main/lua/snippet_converter/core/snipmate/body_parser.lua

Moved to LuaSnip with the aid of snippert-converter, and it's good. No performance issues, easy to setup with nvim-cmp and works well. Would recommend.

Please check out my plugin snippet-converter.nvim which will hopefully save you a lot of time! I have put in a lot of effort to handle as many edge cases as possible so you don't have to worry about line breaks and stuff. Cheers! (Note that this plugin currently only supports vscode_luasnip as a target format not "native" LuaSnip snippets in Lua but VSCode-style snippets should cover 99% of your use cases).

Nice article! Luasnip also supports snippet priorities btw so you don't need to delete them. You could also automate the conversion of the snippets using snippet-converter.nvim (hope no one minds a bit of self-advertising here ;). That should surely speed things up a bit.

No you would need to convert the snippets to VSCode or SnipMate format first. You can do that using a plugin like snippet-converter.nvim (disclaimer: I am the author of that plugin). Simply set the output format to vscode_luasnip or snipmate_luasnip.

Shameless plug: you could also try my plugin https://github.com/smjonas/snippet-converter.nvim which can handle many more edge cases :)

I am excited to announce the release of my first own plugin snippet-converter.nvim that I've been working on for the last couple of months!

You can try my plugin snippet-converter.nvim, it has not been officially released yet but it's already functional. Sorry for the self-promotion but this seems to solve your problem :) It allows you to write your snippets in UltiSnips format and convert them to VSCode snippets.

There does not seem to be a good way to do this at the moment. However, you might be interested in my plugin snippet-converter.nvim that I've been working on for a few months now - the issue you described is one of the use cases of the plugin! It's already usable but there is still some stuff that need to be worked on... If that's done I'll definitely make an announcement on this sub (hopefully in the next weeks) :)

Luacheck is now maintained by lunarmodules.

I first started by reading some tutorials but most of those used parser combinators. For me, parser combinators always caused some issues sooner or later (at least in Lua when trying to parse recursive / nested nodes). An example project that uses this technique is vim-vsnip: https://github.com/hrsh7th/vim-vsnip/blob/master/autoload/vsnip/snippet/parser.vim. Later, I found out that Luacheck uses a different approach which I liked better: https://github.com/lunarmodules/luacheck/blob/master/src/luacheck/parser.lua. That's the project that helped me the most while writing my own parsers for different snippet engines.

I'm just a contributor to Gabe, but I use luacheck in my other projects. Install it (with hererocks+luarocks on Win and luarocks elsewhere), set it up in your editor, and you'll get warnings about typos and other potential bugs. luacheckrc lets you configure it: turn off warnings you don't care about, customize it for different files.

Use luacheck to find all global and unused variables in your project.

I’m not really really sure what exactly you’re relying on that is so specific to Python, but Lu’s appears to have a static analysis linter. https://github.com/luarocks/luacheck
