## Introduction to libei

The libei package contains a set of libraries for handling emulated inputs. It is primarily aimed at the Wayland stack.

### libei Dependencies

#### Optional

libevdev-1.13.6, libxkbcommon-1.13.1, libxml2-2.15.3, munit, and structlog

## Installation of libei

Install libei by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr --buildtype=release -D tests=disabled &&
    ninja

This package does come with a test suite, but it requires an external dependency. If you have both munit and structlog installed, and you wish to run the test suite, run the following commands:

    meson configure -D tests=enabled &&
    ninja test

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.

`-D tests=disabled`: This switch avoids a dependency on munit. Remove this switch if you have munit installed and wish to run the test suite.
