Add a test for the --vsenv meson setup option The tests and the unittests both unconditionally call setup_vsenv() because all tests are run using the backend commands directly: ninja, msbuild, etc. There's no way to undo this vs env setup, so the only way to test that --vsenv works is by: 1. Removing all paths in PATH that provide ninja 2. Changing setup_vsenv(force=True) to forcibly set-up a new vsenv when MESON_FORCE_VSENV_FOR_UNITTEST is set 3. Mock-patching build_command, test_command, install_command to use `meson` instead of `ninja` 4. Asserting that 'Activating VS' is in the output for all commands 5. Ensure that compilation works because ninja is picked up from the vs env. I manually checked that this test actually does fail when the previous commit is reverted.
Meson is available on PyPi, so it can be installed with pip3 install meson. The exact command to type to install with pip can vary between systems, be sure to use the Python 3 version of pip.
If you wish you can install it locally with the standard Python command:
python3 -m pip install meson
For builds using Ninja, Ninja can be downloaded directly from Ninja GitHub release page or via PyPi
python3 -m pip install ninja
More on Installing Meson build can be found at the getting meson page.
Meson can be run as a Python zip app. To generate the executable run the following command:
./packaging/create_zipapp.py --outfile meson.pyz --interpreter '/usr/bin/env python3' <source checkout>
Meson requires that you have a source directory and a build directory and that these two are different. In your source root must exist a file called meson.build. To generate the build system run this command:
meson setup <source directory> <build directory>
Depending on how you obtained Meson the command might also be called meson.py instead of plain meson. In the rest of this document we are going to use the latter form.
You can omit either of the two directories, and Meson will substitute the current directory and autodetect what you mean. This allows you to do things like this:
cd <source root> meson setup builddir
To compile, cd into your build directory and type ninja. To run unit tests, type ninja test.
More on running Meson build system commands can be found at the running meson page or by typing meson --help.
We love code contributions. See the contribution page on the website for details.
The channel to use is #mesonbuild either via Matrix (web interface) or OFTC IRC.
More information about the Meson build system can be found at the project's home page.
