The canonical way to feed your project to cquery is to generate a compile_commands.json file, possibly using cmake. Every time I switch my Mesos work to the cmake build, I live to regret it, either because the component I’m working on isn’t implemented in the cmake build or I end up wanting to install the build (and that isn’t implemented in cmake). So here’s a .cquery file that makes cquery work pretty well with Mesos:

A while ago I tried cquery with Vim, but was a bit unsatisfied with the integration. I could probably have altered my key bindings to perform LSP searches instead of cscope searches, but I also really quite like the integrated tags stack you get with the built-in Vim cscope support. So I thought that it couldn’t be too hard to implement the cscope line protocol with a cquery backend, and it turns out that it wasn’t.
