Germinal

Germinal is Terminal written with the Gtk3 and Vte3 ruby bindings from the project ruby-gnome2. I have written it for testing purpose, but Germinal works well and I use it as my primary terminal emulator.

Features

tabs supports
tabs can be reordered or selected through the preview mode ( Shift + Ctrl + o )
Each tab can be named.
The configuration can be done via a Css file
Terminal colors can be changed on the fly and saved in the CSS configuration file
Terminal font can be changed on the fly and saved in the CSS configuration file
The Css file can be edited in a tab of Germinal and saved. Each modifications are applied while you are writting them. (Use Shift + Ctrl + w to close the editor)
Germinal allows users to modify existing modules. For example if a user copy the css_editor.rb in the directory ~/.config/Germinal/lib/css_editor.rb, he should be able to modify it in order to fit its needs.

TODO:

Regex support in the terminals in order to launch web navigator if there is an url or launch a media player if there is a match for avi file for example.
Create more Css properties in oder to configure the terminals (cursor shape or blink mode, audible bell or not ...)
Make Germinal allows users to easily create their own modules. For example create a tab that will act as a MPD client. There will be widgets that control a MPD server and a GtkTree widget that displays the playlist of the MPD server for example.

Shortcuts

Shift + Ctrl + t new tab
Shift + Ctrl + q quit Germinal
Shift + Ctrl + w close current tab
Shift + Ctrl + left previous tab
Shift + Ctrl + right next tab
Shift + Ctrl + c display color selectors for the vte in overlay mod (Esc to leave)
Shift + Ctrl + f display font selector for the vte in overlay mod (Esc to leave)
Shift + Ctrl + o display previews of all tabs (Esc to leave)
Shift + Ctrl + e open the Css configuration editor in a new notebook tab.

User configuration

It can be found in the file $HOME/.config/Germinal/germinal.css (Be carefull by default Germinal use fish as a default shell, if you want to use another one specify it in the germinal.css file)

Each time you modify this configuration via the interface of Germinal (terminal colors selector, terminal font selector, css editor) and that you save your modifications, Germinal create a copy of your previous Css file under a new name with :

FileUtils.mv(USR_CSS, "#{USR_CSS}_#{Time.new.strftime('%Y-%m-%d-%H-%M-%S')}.backup")

Which means that the old file can be something like that : germinal.css_2016-12-5-13-20.backup.

Installation

Dependancies

gtk3 vte3 sass

Create the gem if needed:

gem build Germinal.gemspec

Install the gem :

gem install Germinal-x.x.x.gem

Launch the terminal

~> Germinal

Tips:

Don't forget, if you install it localy, you need that your system know the path of the ruby gem binaries (for example).

export PATH="${PATH}:/home/${USER}/bin:${HOME}/gem/ruby/2.3.0/bin"

Modifying or testing Germinal is easy:

Get the sources

git clone https://github.com/cedlemo/germinal.git
cd germinal/bin

Edit the files Germinal and test

The filenames correspond to their functionnalities. Simply run ./Germinal when you have done your modifications.

You will need fish shell if you want to test it.
