Bring IDE features for the V programming language to VS Code, Vim, and other editors.

The features provided by v-analyzer include:

• code completion/IntelliSense
• go to definition, type definition
• find all references, document symbol, symbol renaming
• types and documentation on hover
• inlay hints for types and some construction like or block
• semantic syntax highlighting
• formatting
• signature help

v -e "$(curl -fsSL https://raw.githubusercontent.com/vlang/v-analyzer/main/install.vsh)"

The install.vsh file is downloaded to the current directory and stored there temporarily. If there is another file with this name, make sure it is safe when it is overwritten/deleted.

curl -o install.vsh https://raw.githubusercontent.com/vlang/v-analyzer/main/install.vsh; v run install.vsh; del install.vsh

curl -o install.vsh https://raw.githubusercontent.com/vlang/v-analyzer/main/install.vsh && v run install.vsh && del install.vsh

You can download pre-built binaries from the release page. Currently, we provide binaries for Linux (x64), macOS (x64 and ARM), and Windows (x64).

git clone --filter=blob:none --recursive --shallow-submodules https://github.com/vlang/v-analyzer

git submodule init && git submodule update

Update V to the latest version:

v up

You can build a debug or release version of the binary. The debug version will be slower, but faster to compile.

v build.vsh debug

v build.vsh release

The compiled binary will be located in the bin/ folder.

Add the bin/ folder to your $PATH environment variable to make the v-analyzer command easily accessible.

You can also specify the path to the binary in your VS Code settings:

{
	"v-analyzer.serverPath": "/path/to/v-analyzer/bin/v-analyzer"
}

Note Restart VS Code after changing the settings or PATH.

v-analyzer is configured using global or local config. The global config is located in ~/.config/v-analyzer/config.toml, changing it will affect all projects.

A local config can be created with the v-analyzer init command at the root of the project. Once created, it will be in ./.v-analyzer/config.toml. Each setting in the config has a detailed description.

Pay attention to the custom_vroot setting, if v-analyzer cannot find where V was installed, then you will need to specify the path to it manually in this field.

To update v-analyzer to the latest version, run:

v-analyzer up

You can also update to a nightly version:

v-analyzer up --nightly

Note In the nightly version you will get the latest changes, but they may not be stable!

The VS Code extension is available via the VS Code Marketplace. The source code for extension is contained in the editors/code folder of this repository.

For Neovim users, v-analyzer is available via nvim-lspconfig plugin. It is part of the mason registry and could be installed with both Neovim plugins:

• mason.nvim with :MasonInstall v_analyzer command
• mason-lspconfig.nvim with :LspInstall command

• jsonrpc, lsp, tree_sitter_v modules written initially by VLS authors and after that in 2023 it was modified by the VOSCA.

• VLS authors for the initial Language Server implementation!
• vscode-vlang authors for the first VS Code extension!
• rust-analyzer and gopls for the inspiration!
• Tree-sitter authors for the cool parsing library!
