rust.vim VS refactoring.nvim

I am using rustaceanvim and rust.vim.

When the file first loads, it uses the syntax defined in the $VIMRUNTIME/syntax/rust.vim file from rust.vim, which is what I want, but after a few seconds (probably once rust-analyzer loads and runs), it changes the highlighting to use different colours (there's probably a better way to describe it, but a video is easier to show). This colour change also happens when I write the file (and rust-analyzer runs again).

Or this https://github.com/rust-lang/rust.vim, it has example with running tests

If you need basic syntax checking on leaving insert mode (without saving file), https://github.com/rust-lang/rust.vim can be used

Seems like there's a tree-sitter solution, but I do want to note that this works out of the box with rust.vim: https://github.com/rust-lang/rust.vim/issues/63. It might be the built-in Rust support is out of date -- using that repo as a plugin would do the trick.

Most of the customizations in the $VIMRUNTIME's rust ftplugin are guarded behind a flag (g:rust_fold, g:rustfmt_autosave,g:rust_recommended_style, etc.) to control enabling and disabling them, but for some reason the navigation mappings are unconditionally defined, with no flag to turn them off... It might be worth going through the issues in https://github.com/rust-lang/rust.vim to see if that ever came up before.

Is having rust.vim necessary if I'm using rust-tools already?

Primeagen has a series, you could also try spacevim or lunarvim( i prefer lunarvim). If you want to read the docs and setup yourself 1. lsp and code completion mentioned in #5. 2. treesitter 3. lsp handles that, you have to install java's lsp, this improves its look. 4. Make your own remaps, some languages have a plugin for this but i can't find one for java, this is the one for rust. 5. Install cmp and one of the snippet engines.

writing rust is the same regardless of which editor you use and using vim is the same regardless of what programming language you are in, so i dont think you need a tutorial neccissarily. ive been using this plugin for rust-specific features https://github.com/rust-lang/rust.vim

As for plugins for Rust development, I’d recommend Conquer of Completion (using the coc-rust-analyser coc plugin), Rust lang’s rust plugin, and the Toml plugin

Treesitter is a syntax parser that'll build a tree-like structure to enable anything from excellent syntax highlighting through to complex refactoring. There are so many creative ways you can use Treesitter, from jumping around text objects to commenting sections of code, it's a must-have in my books.

Is there any refactoring plugins for Neovim besides https://github.com/ThePrimeagen/refactoring.nvim?

refactoring.nvim is, that I know of, the closest we have to IDE-like refactoring features such as this, but does not have this feature. It would make C development much nicer imo. Perhaps a feature request there may gain traction.

I'm trying to make a naive implementation of command-preview for refactoring.nvim. Currently, my naive implementation is working (since the changes made to a buffer for previewing are discarded by neovim, I'm executing the plugin regularly in order to preview the changes and when the user submits the command to make the changes).

refactoring.nvim and null-ls.nvim may help

refactoring.nvim is one option. Unfortunately what powers VSCode is the proprietary PyLance and AFAIK there is no way to "Move symbol to file (method will be moved) [and have imports renamed subsequently]".

Just a heads up, I added a lot of Ruby support in ThePrimeagen's Refactoring.nvim plugin some time ago. Covers a lot of what you've created and has support for lots of other languages too

It's a pain to learn. I used the online playground and also read a lot of the queries from popular plugins. I contributed Ruby support to refactoring.nvim which helped me learn a tonne too

You might be able to take the ruby one and make an elixir one. It uses tree-sitter queries which you would need to align up with the elixir, but the syntax is kinda close. See https://github.com/ThePrimeagen/refactoring.nvim/blob/master/lua/refactoring/treesitter/langs/ruby.lua
