This is a GUI for o, written in C++, using the VTE library.

Tested with VTE 2.91 on Arch Linux.

If o and cxx are installed, running o main.cpp and then pressing ctrl+space is enough to build the GUI application.

Alternatively, use the Makefile in the parent directory:

make gui

In the parent directory, run:

make gui-install

The font can be set via the O_FONT environment variable, like this:

export O_FONT="Iosevka 12"

Or like this:

export O_FONT="Terminus 10"

The default font is JetBrainsMonoNL 10.

The string is a Pango font description string.
