Got rid of gedit

After discovering that gedit apparently has a memory leak that causes it to consume more and more memory the longer it's left running, and after it corrupted a few .txt files while saving them, I went looking for a replacement.

I sudo apt purge'd gedit, and installed Pluma, which is a fork of gedit. No more memory leaks, no more file corruption.

sudo apt show pluma

Description: official text editor of the MATE desktop environment
 Pluma is a text editor which supports most standard editor features,
 extending this basic functionality with other features not usually
 found in simple text editors. Pluma is a graphical application which
 supports editing multiple text files in one window (known sometimes as
 tabs or MDI).
 .
 Pluma fully supports international text through its use of the
 Unicode UTF-8 encoding in edited files. Its core feature set includes syntax
 highlighting of source code, auto indentation and printing and print preview
 support.
 .
 Pluma is also extensible through its plugin system, which currently
 includes support for spell checking, comparing files, viewing CVS
 ChangeLogs, and adjusting indentation levels.

Another Text Editor which is quite nice is Kate from KDE.

Same. I got rid of Gedit long ago. Pluma is one of my favorites, but I use Xed currently.

Of course, if you've got gedit set up as the default editor for sudoedit in .bashrc, you'll have to remove that line in .bashrc... I've not figured out how to set Pluma as the default sudoedit editor yet.
