Glade2script (aka "g2s") allows a script (bash, python or other) to display and interact with a GUI created with Glade.

It is very convenient for Bash developers who need a GUI more complex than Zenity windows.

Most of the opportunities offered by GTK are available. A terminal (vte) and/or webkit are integrable. One can also embed an external application that supports it natively, like mplayer or gvim. A plugin system was added to extend G2S capability.

Documentation, many examples, and an interface giving access to the archive supports (simply launch presentation.sh).

Glade2script is used by several softwares, such as Boot-Repair, OS-Uninstaller, Debeditor, DeskWall, GUnity, LaunchBash, Malokal, mkv_extractor_gui_v4, Screencastor, Sylaba2, Xee, Zenitor.
