How to debug?

[kirushyk]

Is there a way to set a breakpoint and see what some particular list contains?

I am a personal fan of printf-style debugging.

mylist = ['foo', 'bar']
message('mylist contains: @0@'.format(mylist))

Meson doesn't include an interactive meson.build debugger. If you want to debug meson itself I guess you can run meson with pdb.

It doesn't break when some error happens, also the command 'import pdb' and 'breakpoint()' failed.
meson disabled standard python API?
