Editor Integration

Set up Soli language support in your favorite editor. Full LSP features including autocomplete, hover docs, and real-time linting.

Zero Configuration Required

Install the extension and it just works. The LSP server starts automatically when you open a .sl file.

Cursor & VS Code

The Cursor and VS Code extensions provide the full Soli language experience with LSP support.

Installation

Install from the .vsix package:

cd editors/vscode
vsce package
# Then install .vsix in your editor

Settings

Customize in settings.json:

{
  "soli.lsp.enable": true,
  "soli.lint.onSave": true
}

Neovim

Neovim has built-in LSP support. Configure using lspconfig:

-- ~/.config/nvim/lua/lsp/soli.lua
local lspconfig = require('lspconfig')

lspconfig.soli.setup({
  cmd = {"soli", "lsp"},
  filetypes = {"soli"},
  root_dir = function(filename)
    return lspconfig.util.root_pattern("soli.toml", ".git")(filename)
  end,
  settings = {
    soli = {}
  },
  capabilities = require('cmp_nvim_lsp').default_capabilities(),
})

Or without lspconfig (Neovim 0.10+):

vim.lsp.config('soli', {
  cmd = {"soli", "lsp"},
  filetypes = {"soli"},
  root_markers = {"soli.toml"},
})

vim.lsp.enable('soli')

Other Editors

Any editor that supports the Language Server Protocol can use Soli's LSP server.

{
  "name": "soli",
  "command": "soli lsp",
  "filetypes": ["soli"],
  "rootPatterns": ["soli.toml"],
  "languageId": "soli"
}
