Cog

[Cog (boat)]

[Build - Native] [Build - ARM] [Code Style]

Cog is a small single “window” launcher for the WebKit WPE port. It is small, provides no user interface, and is suitable to be used as a Web application container. The “window” may be fullscreen depending on the WPE backend being used.

This project provides the following components:

  • libcogcore is a library with ready-to-use components typically needed for implementing applications which use the WPE WebKit API.

  • cog is the launcher itself, implemented using the libcogcore library.

  • cogctl is a tool which can be used to control a cog instance using the D-Bus session bus.

It is possible to disable building the cog and cogctl programs by passing -Dprograms=false to Meson.

Dependencies

Stable releases have the following dependencies:

  • WPE WebKit 2.28.x
  • WPEBackend-fdo 1.8.x (optional, recommended)

Note that building from the master branch will often require development releases of WPE WebKit, libwpe, and WPEBackend-fdo; while older Cog releases may have different version requirements.

Using Cog

Compiling Cog follows the usual procedure for projects which use Meson: meson setup build && ninja -C build should get you started, if your system has the needed dependencies installed.

Documentation is available at igalia.github.io/cog but it is currently incomplete. Contributions in this regard are very welcome.

Bug tracking: If you have found a bug, take a look at out issue tracker. Please see the “reporting bugs” section in the CONTRIBUTING.md file for guidelines on how to provide a good bug report.
