craft_parts.plugins.meson_plugin module

The Meson plugin.

class craft_parts.plugins.meson_plugin.MesonPlugin(*, properties, part_info)

Bases: Plugin

A plugin for meson projects.

The meson plugin requires meson installed on your system. This can be achieved by adding the appropriate meson package to build-packages or build-snaps, or to have it installed or built in a different part. In this case, the name of the part supplying meson must be “meson”.

The meson plugin uses the common plugin keywords as well as those for “sources”. Additionally, the following plugin-specific keywords can be used:

• meson-parameters (list of strings) List of parameters used to configure the meson based project.

Parameters:

• properties (PluginProperties)

• part_info (PartInfo)

get_build_commands()

Return a list of commands to run during the build step.

Return type:

list[str]

get_build_environment()

Return a dictionary with the environment to use in the build step.

Return type:

dict[str, str]

get_build_packages()

Return a set of required packages to install in the build environment.

Return type:
