Thank you for contributing.
See wiki: Development for environment setup, tips and tools.
Following are used during CI and strongly recommended during local development.
Language server: luals
Lint: luacheck
Style Fixing: EmmyLuaCodeStyle: CodeCheck
nvim-tree.lua migrated from stylua to EmmyLuaCodeStyle ~2024/10. vim.lsp.buf.format() may be used as it is the default formatter for luals, using an embedded EmmyLuaCodeStyle
You can install them via you OS package manager e.g. pacman, brew or other via other package managers such as cargo or luarocks
The following quality checks are mandatory and are performed during CI. They run on the entire lua directory and return 1 on any failure.
You can run them all via make or make all
You can setup git hooks to run all checks by running scripts/setup-hooks.sh
- Runs luacheck quietly using
.luachecksettings
make lint- Runs lua language server
codestyle-checkonly, using.luarc.jsonsettings - Runs
scripts/doc-comments.shto validate annotated documentation
make styleYou can automatically fix style issues using CodeCheck:
make style-fix- Runs the checks that the LSP lua language server runs inside nvim using
.luarc.jsonviascripts/luals-check.sh
make checkAssumes $VIMRUNTIME is /usr/share/nvim/runtime. Adjust as necessary e.g.
VIMRUNTIME="/my/path/to/runtime" make checkIf lua-language-server is not available or --check doesn't function (e.g. Arch Linux 3.9.1-1) you can manually install it as per ci.yml e.g.
mkdir luals
curl -L "https://github.com/LuaLS/lua-language-server/releases/download/3.9.1/lua-language-server-3.9.1-linux-x64.tar.gz" | tar zx --directory luals
PATH="luals/bin:${PATH}" make checkTo add a new action, add a file in actions/name-of-the-action.lua. You should export a setup function if some configuration is needed.
Once you did, you should run make help-update
When adding new options, you should declare the defaults in the main nvim-tree.lua file.
Documentation for options should also be added to nvim-tree-opts in doc/nvim-tree-lua.txt
When adding or changing API please update :help nvim-tree-api
Please note that nvim-tree team members do not have access to nor expertise with Windows.
You will need to be an active participant during development and raise a PR to resolve any issues that may arise.
Please ensure that windows specific features and fixes are behind the appropriate feature flag, see wiki: OS Feature Flags
Please reference any issues in the description e.g. "resolves #1234", which will be closed upon merge.
Please check "allow edits by maintainers" to allow nvim-tree developers to make small changes such as documentation tweaks.
The merge commit message will be the subject of the PR.
A Conventional Commits subject will be validated by the Semantic Pull Request Subject CI job. Reference the issue to be used in the release notes e.g.
fix(#2395): marks.bulk.move defaults to directory at cursor
Available types:
- feat: A new feature
- fix: A bug fix
- docs: Documentation only changes
- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
- refactor: A code change that neither fixes a bug nor adds a feature
- perf: A code change that improves performance
- test: Adding missing tests or correcting existing tests
- build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
- ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
- chore: Other changes that don't modify src or test files
- revert: Reverts a previous commit
If in doubt, look at previous commits.
