A GNOME Terminal theme generator for themer.
Install this module wherever you have themer installed.
npm install themer-gnome-terminal
Then pass themer-gnome-terminal as a -t (--template) argument to themer:
themer -c my-colors.js -t themer-gnome-terminal -o gen/
themer-gnome-terminal will generate a gnome-terminal-dark-install.sh or gnome-terminal-light-install.sh (or both), depending on which color set you passed to themer.
To install your theme, run the following. Replace Default with the name of your profile. To find out the name of your profile (or to create a new one) go to Preferences -> Profiles in GNOME Terminal.
chmod 755 gnome-terminal-dark-install.sh
./gnome-terminal-dark-install.sh Default
