Tips for using Vim for Chromium development?

[Ilya Sherman]

TL;DR: Does anyone have any tips for effectively using Vim for Chromium development?

---

I'm trying to help a new team member, Aidan, get set up for Chromium development. He prefers to use Vim, which I'm not very familiar with. I'm guessing that there are some plugins/autoformatters that are useful to plug in for Chromium development, but I'm not quite sure where to look. Much to my surprise, the Editor Guides under https://www.chromium.org/developers do not include a page on Vim development.

Does anyone have any tips for Aidan. And, would anyone perhaps be willing to go the extra mile and write up a helpful doc that could be included under the Editor Guides?

Thanks!

There seems to be
https://chromium.googlesource.com/chromium/src/tools/vim/+/HEAD/

But I don't really know much about it...

Welcome, Aidan! I do almost all of my Chromium development in vim.

As Christian said, there's a bunch of stuff in tools/vim. clang-format.vim adds a "format this line" shortcut, which is handy. ninja-build.vim has a "compile this file (or target)" shortcut which I sometimes use.

Some folks like YCM and there's an example config in that folder, but I don't use that myself.

https://github.com/chromium/vim-codesearch is cs.chromium.org integration for vim, which gives you working 'jump to definition' and whatnot. (But I use cs.chromium.org directly most of the time.)

If you have any questions, feel free to ask me on IRC or hangouts :-)

I really really like having buildtools/clang_format/script/clang-format.py and https://gn.googlesource.com/gn/+/master/tools/gn/misc/vim/gn-format.py (personally, I bind to <F1>) instead of using git cl format which I find a bit slow. (There's a GN syntax near there too if you're working on build files.)

Depending on what you're working on, asanka@'s https://github.com/chromium/vim-codesearch can be very helpful.

There's a YCM config file too, but I've always found YCM too much of a hassle to get working, and it makes things feel sluggish when it is working.

ctrlp and alt are two plugins that I use a bazillion times a day on Chromium.

Other than that, just the usual: generate a tags file, and spend a few minutes making sure your tabstop, colorcolumn, encoding, etc. all get set properly when you're in the chromium tree.

Ha, another rule of Chromium development (Vim or otherwise...). Just ask Nico for a quick(er) answer.  ;-)

Welcome Aidan!

Chromium is huge and, therefore, developers greatly benefit from efficient search tools. I found fzf.vim to be the best combination of speed and convenience. I have it integrated into my vimrc using vim-plug, which is also very fast.

Good luck!

Cheers,

Rouslan
