I prefer emacs for day-to-day editing of my code (when I know what's
where), but I'm looking for something to browse around a tree of
unfamiliar source code and make minor changes. I briefly tried
emacs+cscope at a few points in the past, but it just never worked
very well.
It would be nice to have something that I can just point at a tree of
source files and not to have to spend a lot of time setting up a
"project" or "workspace" or whatever...
If emacs has support for compilation databases (a
"compile_commands.json" file), then you can generate one. The easiest
way to do that is with dev-util/bear:
$ bear -- make -j16
This will build the project as usual, but a compile_commands.json file
will be generated in the current directory. Load that file into an
editor or IDE that supports compilation databases.
