Adding a folding text icon in gEdit
Fortunately, jefferyto created a great plugins that allow to wrap/unwrap text with a click of a button.
Install "gedit-toggle-text-wrapping"
First, let's download and extract the plugin
wget https://github.com/jefferyto/gedit-toggle-text-wrapping/archive/master.zip unzip master.zip
Then, lets create the plugin folder
mkdir -p ~/.local/share/gedit/plugins
Now, we need to copy the right file based on the version of gEdit.
gedit --version
IF the version if 3.6 or less:
cp toggletextwrapping.plugin.python2 ~/.local/share/gedit/plugins/toggletextwrapping.plugin
IF the version is 3.8 or newer:
cp toggletextwrapping.plugin ~/.local/share/gedit/plugins/toggletextwrapping.plugin
Copy the plugin
cp -r toggletextwrapping ~/.local/share/gedit/plugins
Activate plugin
Restart gedit
Now, navigate to "Edit -> Preferences
Select the "plugins" tab and check the "Toggle Text Wrapping".
to wrap or unwrap text, you can either click on the Green Check or by using the keyboard shortcut: Ctrl+Shift+B
