Build the current file

[zenangst]

Hey,

First, thanks for an amazing NeoVim plugin ❤️

In Xcode, you have the option to build the current file you're viewing. This option is usually much faster than compiling the current target to ensure it doesn't contain any compiler errors. I'd love to have that kind of functionality for ~xcodebuild.nvim.

I might have missed something, and this might be possible today. If so, then I might have simply overlooked it.

Hmm, you don't have to compile the app manually, the syntax check happens automatically. The LSP should show all errors immediately. Of course, the sourcekit-lsp is a little bit clunky and it doesn't always see global changes.

If you don't see syntax errors then most likely the LSP is not configured properly.

I'm also not sure what do you mean by "build the current file". Usually the file is connected with many other files because it uses models, etc. so in a normal project that would be rarely usable, maybe just for some Foundation extensions or simple views. Where is that option in Xcode?

This is the functionality that I'm referring to inside Xcode.

Oh, I do get the warnings and errors to show up. Was just curious if this was something that could be added to reduce some of the strain on a recompile as you are fixing the issues. Perhaps I'm just stuck in my Xcode-based workflow in my head.

And the sourcekit-lsp actually runs in the background and recompiles files on the fly to show you errors and warnings, so you shouldn't have to manually trigger it while editing a file. Of course, it's not perfect, so usually you need to build the app at some point.

Thanks for the follow-up ❤️

You can compile the current file using Neovim's built in :make command. You'll want to look into make, makeprg, and compiler. Here is a compiler file for building swift. It specifies the error format, so you can get errors in your quick fix window. This should work with vi, vim, and neovim.

" ~/.config/nvim/compiler/swift.vim
" Compile standalone Swift file (release)
setlocal makeprg=swiftc\ -O\ %\ -o\ %:r
setlocal errorformat=%f:%l:%c:\ %m

It won't work for iOS app, I guess. Each file has many dependencies, requires linked libs etc. So probably it would only for small Swift Packages unless I'm missing something :D.

[craig-miller]

Yep, it won't work for iOS apps. The same basic approach does work for swift scripts, individual swift files that don't depend on external swift packages, and I have a similar configuration for projects managed with swift package manager (like vapor projects and embedded swift projects). I have an auto command to automatically configure make depending on what it finds in the directory root.

I use your Xcodebuild for full Xcode based projects. It would be cool to configure makeprg to build Xcodebuild projects for a more Neovim native approach to building. :make
