KDE Advanced Text Editor (Kate) is an open-source text editor developed by the KDE community. It has several advanced text editor features, but no IDE-specific features like: code-completion, script running, projecting building or code linting.

Installation

It comes pre-installed with the Fedora KDE Spin, but on other spins of Fedora, or on Fedora workstation (which utilizes the GNOME desktop environment) one will need to install it manually, by running:

$ sudo dnf install kate
