Fuchsia Language Server

LSP server for Fuchsia-specific languages (FIDL, CML).

What's here?

• /lsp: The Language Server implementation
• /chava: A flexible parser & utilities for FIDL in Rust

See the individual subdirectories for more information.

How do I build this?

All crates here use a normal Rust build process. The LSP server itself is the default project for this workspace, so you can simply run cargo build --release from the root of the repository and get a built LSP in /target/release.

How do I use this?

See /lsp for more details, but the TL;DR is:

• If using VS Code, grab the Fuchsia extension, which comes with a prebuilt copy, or can be configured to use a custom copy in the extension settings

• Otherwise, follow the appropriate editor configuration for adding language servers to your editor. For example, for neovim with nvim-lspconfig:

  require('lspconfig.configs').fuchsialsp = {
  	default_config = {
  	  name = 'Fuchsia Language Server',
  	  cmd = {'/path/to/your/built/lsp'},
  	  filetypes = {'fidl', 'cml'},
  	  -- this'll be changing a bit in the future to be clearer
  	  root_dir = require('lspconfig').util.find_git_ancestor,
  	}
  }
  require('lspconfig').fuchsialsp.setup {
    -- your setup here
  }
