[REQUEST] Autocompletion

[JoeJoeTV]

Adding Autocompletion for commands,id's,etc would be very useful.

I'm considering this for the version-specific grammars based on the game's commands.json and registries.json, but because autocompletion requires a language server I want to focus on finishing the syntax highlighting first.

Here's a langserver project in-the-works for 1.13+ you might be interested in: https://github.com/Levertion/mcfunction-langserver

Thanks for replying so fast, but I'm interested what exactly a language server is and where you can get the commands.json and registries.json, can you extract them from the class files in the jar?
Previously I was using another extension for VSCode named datapack-helper whis had auto completion but I think only for maybe 1.13.

A language server is a type of extension for VSCode, required for almost any language features beyond basic syntax highlighting: https://code.visualstudio.com/api/language-extensions/language-server-extension-guide

As for Minecraft's generated data: yes, it's been available since 1.13 snapshots. There's some good stuff in there, you can have a look here: https://github.com/Arcensoth/mcdata

And here's commands.json from the most recent snapshot (apparently it hasn't changed since 19w02a): https://github.com/Arcensoth/mcdata/blob/master/generated/reports/commands.json

Closing this issue because the requested feature is already planned for the version-specific grammars.

Closing the issue permanently after deciding that language-mcfunction will focus on language grammar definitions and syntax highlighting, and that LSP features are out-of-scope. Here are some other extensions for mcfunction and datapack LSP support:
