## Installation of libpeas

Install libpeas by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr          \
                --buildtype=release    \
                --wrap-mode=nofallback \
                ..                     &&
    ninja

If you have Gi-DocGen-2024.1 installed and wish to build the API documentation for this package, issue:

    sed "/docs_dir =/s@\$@/ 'libpeas-1.36.0'@" \
        -i ../docs/reference/meson.build       &&
    meson configure -D gtk_doc=true            &&
    ninja

To test the results, issue: ninja test. An active graphical session with bus address is necessary to run the tests.

Now, as the `root` user:

    ninja install

## Command Explanations

`--buildtype=release`: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

`--wrap-mode=nofallback`: This switch prevents meson from using subproject fallbacks for any dependency declarations in the build files, stopping it downloading any optional dependency which is not installed on the system.

`-D vapi=true`: Add this switch if you wish to generate vapi (vala) data.

`-D demos=false`: Add this switch if you do not wish to build the demo programs.
