Mise Cookbook Neovim

There are two mise.toml files in play:

1. Global (~/.config/mise/config.toml) — pins Neovim itself and global LSPs/formatters.
2. Per-project — each project's mise.toml pins its language runtime. Neovim inherits tools via the shims-on-PATH pattern.

The global ~/.config/mise/config.toml

The Neovim init.lua snippet

Put this before any plugin loader or LSP config:

-- ~/.config/nvim/init.lua (or lua/mise.lua sourced early)

-- Prepend mise shims to PATH so every subprocess Neovim spawns — LSPs, formatters,
-- linters, terminal — inherits the mise-managed tools.
local mise_shims = vim.fn.expand("~/.local/share/mise/shims")
if vim.fn.isdirectory(mise_shims) == 1 then
  vim.env.PATH = mise_shims .. ":" .. vim.env.PATH
end

That's the only mise-specific piece. Everything else is standard Neovim config.

LSP setup with nvim-lspconfig

-- lua/plugins/lsp.lua
local lspconfig = require("lspconfig")

-- Each LSP is found via PATH, so mise shims resolve to the project-correct version.
lspconfig.pyright.setup({})
lspconfig.ts_ls.setup({})
lspconfig.gopls.setup({
  settings = {
    gopls = {
      gofumpt = true,
      staticcheck = true,
    },
  },
})
lspconfig.rust_analyzer.setup({
  settings = {
    ["rust-analyzer"] = {
      cargo = { features = "all" },
      checkOnSave = { command = "clippy" },
    },
  },
})
lspconfig.marksman.setup({})
lspconfig.lua_ls.setup({
  settings = {
    Lua = {
      workspace = { library = vim.api.nvim_get_runtime_file("", true) },
      diagnostics = { globals = { "vim" } },
    },
  },
})

No cmd = { "/abs/path/to/pyright" } hacks — lspconfig finds each LSP from PATH, and PATH has mise shims prepended.

Formatting via conform.nvim

-- lua/plugins/conform.lua
require("conform").setup({
  formatters_by_ft = {
    python = { "ruff_format", "ruff_fix" },
    go = { "gofumpt" },
    javascript = { "prettier" },
    typescript = { "prettier" },
    javascriptreact = { "prettier" },
    typescriptreact = { "prettier" },
    json = { "prettier" },
    yaml = { "prettier" },
    markdown = { "prettier" },
    lua = { "stylua" },
  },
  format_on_save = {
    timeout_ms = 500,
    lsp_fallback = true,
  },
})

conform.nvim also finds formatters via PATH. All are mise-installed.

Linting via nvim-lint

-- lua/plugins/lint.lua
require("lint").linters_by_ft = {
  python = { "ruff" },
  sh = { "shellcheck" },
  bash = { "shellcheck" },
}

vim.api.nvim_create_autocmd({ "BufWritePost" }, {
  callback = function() require("lint").try_lint() end,
})

What this gives you

• Project-aware LSPs — gopls in project A uses the Go pinned by project A's mise.toml. Switch projects, gopls auto-switches Go versions. Zero config.
• Pinned editor tooling — the whole team running the same LSP / formatter versions means no "ruff formatted differently" noise in diffs.
• One install command — mise install pulls Neovim, all LSPs, all formatters, all linters.
• No mason.nvim — you don't need mason's download layer because mise is the layer. Saves a whole plugin.

First-run walkthrough

# 1. Install mise on the host if you haven't.
curl https://mise.run | sh
eval "$(mise activate zsh)"

# 2. Write ~/.config/mise/config.toml with the [tools] block above.
vim ~/.config/mise/config.toml

# 3. Install everything.
mise install

# 4. Open Neovim from any project dir.
cd ~/projects/myapp
nvim

# 5. Verify LSPs are reachable:
#    :LspInfo
#    :checkhealth lsp

Mason.nvim interop (if you want both)

If you already have mason and don't want to rip it out:

-- Make sure mason's bin dir is AFTER mise shims on PATH
local mison_bin = vim.fn.stdpath("data") .. "/mason/bin"
if vim.fn.isdirectory(mison_bin) == 1 then
  vim.env.PATH = mise_shims .. ":" .. mison_bin .. ":" .. vim.env.PATH
end

Now mise shims win when a tool is available via both. Slow migration path: move one LSP at a time from mason to mise, uninstall from mason.

Common gotchas

1. Launching Neovim via Alfred/Spotlight/Raycast → Desktop launchers skip shell rc. The vim.env.PATH line in init.lua is essential for this case. Don't skip it.
2. :checkhealth lsp reports "pyright not found" → PATH isn't set correctly or mise shims are missing pyright. Verify which pyright in a shell, then :echo $PATH inside Neovim.
3. gopls finds the wrong Go version → gopls uses go version to resolve. mise shims handle this per-project automatically. If you see drift, check mise current go in the project dir.
4. Formatter runs but diff looks stale → conform.nvim's format_on_save is async; if you save-and-quit in one motion, you may beat the formatter. Use :Format then :w.
5. Multi-root workspaces → lspconfig picks one root per buffer. That's an lspconfig limitation, not mise's.
6. TSInstall <lang> needs a C compiler → Treesitter compiles parsers from C. Install aqua:llvm/llvm-project globally or rely on system clang.
7. Emacs / Helix users → Same pattern. Set exec-path/PATH to include mise shims early in init.
