LSP (Language Server Protocol)

SpaceVim uses nvim-lspconfig (neovim native LSP) via the lsp layer. Active clients are declared in SpaceVim.d/init.toml under [[layers]] name = "lsp".

[[layers]]
name = "lsp"
enabled_clients = ['pyright', "gopls", "tsserver", "sourcekit", "solargraph", "rust_analyzer"]

Keymaps (all LSP-enabled filetypes)

Key Action
gd Go to definition
gD Go to type definition
gr Find references
gi Go to implementation
K Show hover documentation
<leader>rn Rename symbol
SPC l d Show document
SPC l e Rename symbol
SPC l s Show line diagnostics
SPC l x Find references

Clients & Installation

Python — pyright

npm install -g pyright

Go — gopls

go install golang.org/x/tools/gopls@latest

Custom flag in config (shared daemon mode):

[layers.override_cmd]
gopls = ['gopls', '-remote=auto']

TypeScript / JavaScript — tsserver

npm install -g typescript typescript-language-server

gd uses _typescript.goToSourceDefinition to jump to source instead of stopping at re-exports.

Swift / ObjC — sourcekit

Bundled with Xcode. Requires Xcode to be installed and selected:

xcode-select --install
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Root detection is customised in SpaceVim.d/lua/lingti/lsp.lua to prefer Package.swift over .git for Find References to work in multi-package repos.

Ruby — solargraph

gem install solargraph

Rust — rust_analyzer

Install via rustup (recommended — keeps in sync with the toolchain):

rustup component add rust-analyzer

Verify:

rust-analyzer --version

Note: rust-analyzer is a toolchain component, not a standalone binary in PATH. The rustup-managed wrapper at ~/.cargo/bin/rust-analyzer is what nvim-lspconfig invokes.

Diagnostics

Diagnostics are handled by the checkers layer (ALE engine):

[[layers]]
name = "checkers"
enable_ale = true
Key Action
SPC l s Show current line diagnostics
]e / [e Jump to next/previous error

Troubleshooting

Check if an LSP client is attached to the current buffer:

:lua print(vim.inspect(vim.lsp.get_clients({bufnr=0})))

Check LSP log for errors:

:lua vim.cmd('edit ' .. vim.lsp.get_log_path())

Verify the binary is executable:

which rust-analyzer
which gopls
which pyright
which typescript-language-server
which solargraph

Reload LSP for current buffer:

:LspRestart
