Re: [cdt-dev] Are managed projects a requirement/recommendation or the new build system is enough?

I did not check the source code, but, at least in theory, it does not need to parse the output, since it already knows the full command line for each file (because it generates it).

users do not need to teach the indexer separately, users need to teach the build system about the include paths and macros, the indexer is an indirect beneficiary.

I'm not very concerned about the current UI, I'm more concerned on the internals.
is there any API to teach the indexer what are the command lines for each file? ideally it should be one to parse the command_commands.json.

according to my tests, cdt-cmake was not very encouraging, for unknown reasons the indexer did not go into system headers.

really? parsing CMakeLists.txt is not exactly a joyride.

all 3 builder generators considered for my use case (cmake, meson, xpbuild) create the command_commands.json file, so I would start by assuming that this file is available, and do not bother with parsing console output.
