Fast, typesafe, Vim plugins with the power of Swift!
SwiftForVim integrates the Swift Programming Language into Vim.
Vimscript <-> Swift
Calling Vim commands from Swift
Vim.command("echo 'Hello World!'")Evaluating Vim expressions from Swift
let path = String(Vim.eval("expand('%:p')"))Call Swift functions from Vim
VimPlugin.setCallable("cursorMoved") {
_ in
print("The cursor moved")
}
// Off in VimScript
call s:SwiftVimEval("MyAwesomePlugin.invoke('cursorMoved')")Threading and Async support for Vim
DispatchQueue.async {
// Do some work
VimTask.onMain {
Vim.command("echo 'Hello World! on the main thread.'")
}
}Note: VimAsync depends on Foundation. Its not needed for basic, single threaded plugins.
First, generate a Vim Plugin setup to use Swift.
git clone https://github.com/swift-vim/SwiftForVim.git
cd SwiftForVim
plugin_path=/path/to/MyAwesomePlugin make generateThen, build the plugin.
cd /path/to/MyAwesomePlugin
makeLast, setup the plugin ( VimPlug, Pathogen, etc ).
Portable, fast, and simple to use.
It doesn't require recompiling Vim or a custom fork of the Swift language.
Swift makes it easy to build fast, type safe programs, that are easy to debug and deploy.
The source tree contains a very basic example and test case.
SwiftPackageManger.vim is the canonical use case and uses VimAsync to run a custom RPC service inside of vim.
