Development

SpaceVim is a joint effort of all contributors. We encourage you to participate in SpaceVim’s development. This page describes the entire development process of SpaceVim.

We have some guidelines that we need all contributors to follow. You can only think about reading the part that is relevant to what you are going to do:

Contributing code

Code and documentation contributions of any kind are welcome. In any case, feel free to chat with us to ask questions about contributing!

License

The license is GPLv3 for all the parts of SpaceVim. This includes:

For files not belonging to SpaceVim like bundle packages, refer to the header file. Those files should not have an empty header, we may not accept code without a proper header file.

Conventions

SpaceVim is based on conventions, mainly for naming functions, keybindings definition and writing documentation. Please read these conventions to make sure you understand them before you contribute code or documentation for the first time.

Commit style guide

Follow the conventional commits guidelines to make reviews easier and to make the git logs more valuable. The general structure of a commit message is:

<type>([optional scope]): <description>

[optional body]

[optional footer(s)]

types:

scopes:

In addition to these scopes above, you can also use a specific layer name or plugin name as a scope.

subject:

Subjects should be no greater than 50 characters, should not begin with a capital letter and do not end with a period.

Use an imperative tone to describe what a commit does, rather than what it did. For example, use change; not changed or changes.

body:

Not all commits are complex enough to warrant a body, therefore it is optional and only used when a commit requires a bit of explanation and context.

footer

The footer is optional and is used to reference issue tracker IDs.

Breaking change

Breaking changes must be indicated by “!” after the type/scope, and a “BREAKING CHANGE” footer describing the change. Example:

refactor(tools#mpv)!: change default musics_directory

BREAKING CHANGE: `~/Music` is standard on macOS and
also on FreeDesktop's XDG.

Pull Request

Prefix of title

The title of a pull request should contain one of the following prefixes::

Here is an example:

Website: Update the lang#c layer page.

Workflow

git clone ${YOUR_OWN_REPOSITORY_URL}

git remote add upstream https://github.com/SpaceVim/SpaceVim.git

git fetch upstream
git rebase upstream/master

Simple PRs

Complex PRs

Squash only the commits with uninteresting changes like typos, syntax fixes, etc. And keep the important and isolated steps in different commits.

Those PRs are merged and explicitly not fast-forwarded.

Contributing a layer

Please read the layers documentation first.

Layer with no associated configuration will be rejected. For instance a layer with just a package and a hook can be easily replaced by the usage of the variable custom_plugins.

File header

The file header for Vim script should look like the following template:

"=============================================================================
" FILENAME --- NAME layer file for SpaceVim
" Copyright (c) 2016-2022 Wang Shidong & Contributors
" Author: Wang Shidong < [email protected] >
" URL: https://spacevim.org
" License: GPLv3
"=============================================================================

You should replace FILENAME by the name of the file (e.g. foo.vim) and NAME by the name of the layer you are creating, don’t forget to replace YOUR NAME and YOUR EMAIL too.

Author of a new layer

In the file’s header, replace the default author name (Shidong Wang) with your name.

The following example shows how to create a new layer named foo:

  1. Fork SpaceVim repo.
  2. Add a layer file autoload/SpaceVim/layers/foo.vim for foo layer.
  3. Edit layer file, check out the example below:
"=============================================================================
" foo.vim --- foo Layer file for SpaceVim
" Copyright (c) 2012-2022 Shidong Wang & Contributors
" Author: Shidong Wang < [email protected] >
" URL: https://spacevim.org
" License: GPLv3
"=============================================================================

  1. Create the layer’s documentation file docs/layers/foo.md for foo layer.
  2. Open docs/layers/index.md, and run :call SpaceVim#dev#layers#update() to update the layers list.
  3. Send a PR to SpaceVim.

Contributor to an existing layer

If you want to contribute to an already existing layer, you should not modify any header file.

Contributing a keybinding

Mappings are an important part of SpaceVim.

First if you want to have some personal mappings. This can be done in your bootstrap function.

If you think it is worth contributing new mappings, be sure to read the documentation to find the best mappings, then create a Pull-Request with your mappings.

ALWAYS document your new mappings or mapping changes inside the relevant documentation file. It should be the layername.md and the documentation.

Language specified key bindings

All language specified key bindings have the prefix SPC l.

We recommend you to use the common language specified key bindings for the same purpose as the following:

Key Binding Description
g d jump to definition
g D jump to type definition
SPC l r start a runner for current file
SPC l e rename symbol
SPC l d show doc
K show doc
SPC l i r remove unused imports
SPC l i s sort imports with isort
SPC l s i Start a language specified inferior REPL process
SPC l s b send buffer and keep code buffer focused
SPC l s l send line and keep code buffer focused
SPC l s s send selection text and keep code buffer focused

All above key bindings are just recommended as default, but they are also based on the language layer itself.

Contributing a banner

The startup banner is the SpaceVim logo by default. but there are also ASCII banners available in the core/banner layer.

If you have some ASCII skills you can submit your artwork!

You are free to choose a reasonable height size. but the width size should be around 75 characters.

Build with SpaceVim

SpaceVim provides a lot of public APIs, you can create plugins based on these APIs. Also you can add a badge to the README.md of your plugin.
