Here is an incomplete stack of tricks to help you work with Chromium in Visual Studio.
Faster Solution Loading / IntelliSense
Loading a huge solution (like all.sln as generated by gn) makes Visual Studio very slow, and certain operations like IntelliSense can be somewhat unusable. Some tips for speeding it up:
- Use the "filters" argument to gn to exclude parts of Chromium you're not interested in, e.g. "gn gen --ide=vs --filters=//components/omnibox/* --sln=omnibox out/Debug" will only create projects for components/omnibox/ and its dependencies. However, be aware that Code Search (see below) will not work on code that's been filtered out!
- A very useful extension which helps manage this is VsFunnel. This extension allows you to select which projects in a solution will be loaded at solution load time, and which will remain in the "unloaded" state. Unloaded projects are not indexed by VS, so this extension can drastically speed up VS responsiveness. The unloaded projects will remain searchable via VsChromium (see below).
After opening the solution, give Visual Studio about 10-15 minutes to finish parsing files etc; it'll become more responsive after that.
The VsChromium extension provides fast code search, among other useful features. Code from unloaded solutions (via VsFunnel, see above) is still searchable!
You can set up column guidelines at 80 columns or wherever you would like by installing this Visual Studio extension and using the context menu options.
cpplint.py integration makes it easy to check that a source file conforms to the style guide. To do this, just go to Tools > External Tools > Add. Specify:
- Title: cpplint.py
- Command: C:\depot_tools\python_bin\python.exe
- Arguments: C:\depot_tools\cpplint.py --output=vs7 $(ItemPath)
- Initial directory: $(ItemDir)
- Check Use Output window
To create a keyboard shortcut:
- Go to Tools > Options > Environment > Keyboard.
- Select Tools.ExternalCommand1. (This assumes cpplint.py is your first external command in your Tools menu.)
- Press a shortcut key (let's say Alt+L) and Assign it.
- Press OK.
Text Editor (No tabs, indentation, line numbers)
The style guide requires no tabs and 2 char indentation. To set this, go to Tools > Options. On the Text Editor/All languages/Tabs page, set
- Indenting radio to Smart
- Tab size and Indent Size to 2
- Check Insert spaces
