Any supports for neoconf ?

[TD-Sky]

I use .neoconf.json to configure rust-analyzer locally. Now I cannot setup LSP client via nvim-lspconfig as rustaceanvim will do it. So are there any other ways to pass the project local settings?

Hey 👋

Which settings do you need to configure on a per-project basis?
I plan on adding support for loading rust-analyzer settings from JSON (see #51).

Neoconf requires a setup call, which I view as potentially problematic, because it means that users have to worry about initialization order. In the case of this plugin, it might be fine though, as the config is initialised lazily when opening a Rust file.

I'll create a feature request for now (#53), and look into it when I have some more time.
PRs are also more than welcome 😄

Here's the example coming from the project RISC-V based system kernel.

// .neoconf.json
{
  "lspconfig": {
    "rust_analyzer": {
      "rust-analyzer.checkOnSave.command": "clippy",
      "rust-analyzer.checkOnSave.allTargets": false,
      "rust-analyzer.cargo.target": "riscv64gc-unknown-none-elf"
    }
  }
}

Those are rust-analyzer settings, so it can be solved with #51 (which I've just implemented and released).

See the section in the readme for details.

The JSON would have to look like this:

{
  "rust-analyzer": {
    "checkOnSave.command": "clippy",
    "checkOnSave.allTargets": false,
    "cargo.target": "riscv64gc-unknown-none-elf"
}

If you want to reuse your neoconf settings, you can use this function as a reference to load them.

I do plan to add support for neoconf, but unfortunately I don't have time for that right now (probably not before December).

Really helpful ! Thanks for your work.

The JSON would have to look like this:

{
  "rust-analyzer": {
    "checkOnSave.command": "clippy",
    "checkOnSave.allTargets": false,
    "cargo.target": "riscv64gc-unknown-none-elf"
}

To inform anyone reading the solution when you migrate the setting from neoconf, you can copy and paste the content in rust_analyzer instead of making the above form. i.e.

// .neoconf.json
{
-  "lspconfig": {
-    "rust_analyzer": {
      "rust-analyzer.checkOnSave.command": "clippy",
      "rust-analyzer.checkOnSave.allTargets": false,
      "rust-analyzer.cargo.target": "riscv64gc-unknown-none-elf"
-    }
-  }
}

to obtain:

// rust-analyzer.json under project root
{
      "rust-analyzer.checkOnSave.command": "clippy",
      "rust-analyzer.checkOnSave.allTargets": false,
      "rust-analyzer.cargo.target": "riscv64gc-unknown-none-elf"
}

then use :RustAnalyzer reloadSettings to reload the config without restarting.
