Jollpi is a lightweight graphical text editor for Linux built with Python 3, GTK 4, and GtkSourceView 5. It is a modern rewrite of the original Jollpi editor, which dates back to the Python 2 and GTK 2 era. The rewritten application retains the project’s emphasis on simplicity while adopting the current GNOME technology stack.
The editor sits between very basic notepad-style applications and heavyweight programming environments. Its interface remains uncomplicated, but GtkSourceView gives it facilities that make it useful for editing source code as well as ordinary text documents. Multiple documents can be kept open at once without introducing the project-management concepts associated with an IDE.
Particular attention has also been paid to file handling. Jollpi can open files asynchronously, with operations that can be cancelled, helping the graphical interface remain responsive when dealing with large documents. It can also watch open files for changes made by other applications, a useful facility when the same document is being processed by external tools.
This is free and open source software.
