Indentation of list argument broken.

[Janfel]

The Meson Style Guide contains this piece of code:

sources = files([
  'aaa/a1.c',
  'aaa/a2.c',
  'bbb/subdir1/b1.c',
  'bbb/subdir2/b2.c',
  'bbb/subdir10/b3.c',
  'bbb/subdir20/b4.c',
  'bbb/b5.c',
  'bbb/b6.c',
  'f1.c',
  'f2.c',
  'f10.c',
  'f20.c'
])

When I copy this into Emacs and indent it, the output is this:

sources = files([
                 'aaa/a1.c',
                 'aaa/a2.c',
                 'bbb/subdir1/b1.c',
                 'bbb/subdir2/b2.c',
                 'bbb/subdir10/b3.c',
                 'bbb/subdir20/b4.c',
                 'bbb/b5.c',
                 'bbb/b6.c',
                 'f1.c',
                 'f2.c',
                 'f10.c',
                 'f20.c'
               ])

This seems like unintended behavior to me.

Hmm, meson-mode indentation was implemented before there was any style guide and adheres to how indentation in many other emacs modes works. But I understand that it makes sense to support recommended indentation style. I'll look at that, but it may take me some time.

Most probably, I'll make the indentation style configurable with the meson recommended style being the default and allowing people to switch to the previous "emacs style" if they want.

It seems I was able to fix this even without introducing a "indentation style" configuration variable. I tested the above commit with meson.build files from a few projects and I didn't see any unwanted indentation breakage.

Reopening this. The current solution is not ideal. List arguments are indented according to the style guide, but non-list argument are indented differently.

lib = static_library('mylib', [
	'getopt.c',
	'lib.c',
	'math.c',
],
	             include_directories : include_directories('include'),
	             c_args : '-Dxxx',
                    )

I'll need to figure out, how to handle this consistently. Suggestions welcome :-)
