How can I create custom themes Pluma editor for anyone to use?

  • 772

Ubuntu MATE 20.10 groovy

enter image description here This "Pluma" code editor comes with Ubuntu mate

In pluma > preferences > fonts & colors > Color scheme it states:

You can add a new color scheme by clicking on Add..., and selecting a color scheme file
You can remove the selected color scheme by clicking on Remove

Where are these files placed? and are they CSS files? I would like to create some additional themes for everyone to use.

  1. Let's start from the existing ones. For example Oblivion color scheme:

    $ dpkg -S oblivion
libgtksourceview-3.0-common: /usr/share/gtksourceview-3.0/styles/oblivion.xml

    The line above says that this file came from libgtksourceview-3.0-common package.
    It is XML file. Its syntax is covered by Style Scheme Definition Reference.

    To start hacking one can create local version of Oblivion theme by copying it to the corresponding folder and renaming it to Oblivion-mod:

    mkdir -p ~/.local/share/gtksourceview-3.0/styles
cp /usr/share/gtksourceview-3.0/styles/oblivion.xml ~/.local/share/gtksourceview-3.0/styles/oblivion-mod.xml

sed -i "s/oblivion/oblivion-mod/g" ~/.local/share/gtksourceview-3.0/styles/oblivion-mod.xml
sed -i "s/Oblivion/Oblivion-mod/g" ~/.local/share/gtksourceview-3.0/styles/oblivion-mod.xml
sed -i "s/Dark color/Modified dark color/" ~/.local/share/gtksourceview-3.0/styles/oblivion-mod.xml

    and then apply this theme and continously edit the file.

    Also note that there are some style collections on the net:
