Here is a typical meson.build file, from the project gnome-builder:

project('gnome-builder', 'c', license: 'GPL3+', version: '3.26.4', meson_version: '>= 0.40.1', default_options: [ 'c_std=gnu11', 'cpp_std=c++11', 'warning_level=2', 'with_channel=other', ], )

version_split = meson.project_version().split('.') MAJOR_VERSION = version_split[0] MINOR_VERSION = version_split[1] MICRO_VERSION = version_split[2]

pkgdocdir_abs = join_paths(get_option('prefix'), get_option('datadir'), 'doc', 'gnome-builder') pkglibdir_abs = join_paths(get_option('prefix'), get_option('libdir'), 'gnome-builder') pkglibdir = join_paths(get_option('libdir'), 'gnome-builder') pkgincludedir = join_paths(get_option('includedir'), 'gnome-builder') pkggirdir = join_paths(get_option('datadir'),'gnome-builder', 'gir-1.0') pkgtypelibdir = join_paths(get_option('libdir'), 'gnome-builder', 'girepository-1.0') pkgvapidir = join_paths(get_option('datadir'), 'gnome-builder/vapi')

I think it is a python file. Would it work to just associate ".meson" file types with the ".py" extension? Is there a document that describes how to add such a new file type (or associate with it?)

If it is really just a python file then it may be enough to just append ".meson" as to how .py files are parsed.

Not sure where the filetypes are defined; one file I found via grep was

**data/filetype_extensions.conf**:Python=*.py;*.pyw;SConstruct;SConscript;wscript;

I don't know if this is really the "right" way, but it's working for now.

After you create the file below, edit `filetype_extensions.conf` and add

`Meson=*.build`

## filetypes.Meson.conf
