Is `meson.source_root()` the project root directory?

Question

Is the directory return by meson.source_root() the project root directory (with the root level meson.build file) or is it the path of the current meson.build file being processed?

Answer 1

The project root directory is obtained with the following meson syntax:

meson.source_root()

The current source directory can be obtained with the following meson syntax:

meson.current_source_dir()

Something "disturbing" is that current_source_dir() gives a relative path to the source_root(), so I always need to do join_paths(meson.source_root(), meson.current_source_dir()). – Laser

@slamander I just tried what you suggested and it didn't work for me. It's possible we're talking about different things, but if have source root /some/dir and current source dir some/dir/src then current_source_dir() gives me /some/dir/./src and join_paths() as you show above gives me the same thing. I did the following to fix this, but there may be a better/easier way (it's my first day with meson): curDir = meson.current_source_dir() curDir = curDir.split('.') curDir = curDir[0] + curDir[1] curDir = curDir.split('//') curDir = join_paths(curDir[0], curDir[1]) – Counts

Ran out of space in my previous comment, but the code I provided there is brittle if you have dirtectory names that contain '.' characters. What I did was to encose everything after the curDir = meson.current_source_dir() in if ( curDir.contains('/./') ) to ensure it doesn't execute on random '.' chars. – Counts

Please mention that source_root() is deprecated in preference of (depending on what you want): current_source_dir(), project_source_root(), or global_source_root(). – Remittent
