Installing

Vscode

Install the extension here. Then, it will prompt you to allow the extension to autoinstall the server binary from the releases page. Alternatively, you can build slang-server and set slang.path to that binary.

Vscode Forks (Cursor, Antigravity, VSCodium, etc.)

Install from your editor, or download from the OpenVSX Marketplace

Neovim

slang-server is available in nvim-lspconfig as slang_server (note the underscore) and in the mason.nvim package registry as slang-server, so no additional configuration is required in most cases. The default configuration shipped with nvim-lspconfig can be found here.

Install the binary via :MasonInstall slang-server (or otherwise place it on PATH), then enable the server with vim.lsp.enable("slang_server"), or follow your own Neovim configuration's convention for enabling servers.

Restart and run :LspInfo to make sure the LSP was correctly installed.

Enhanced features

Once the language server is installed, it is recommended to install the slang-server.nvim plugin; this provides enhanced HDL specific features such as design hierarchy view and waveform integration.

Other editors

Most modern editors can at least point to a language server binary for specific file types. This will provide standard LSP features, but not HDL specific features.

If the editor also allows for executing LSP commands, HDL features like setting a compilation should be available.
