Lite XL

Lite XL is a very lightweight yet powerful text editor, comparable to Notepad++ for Windows or the KDE editor Kate. Because it uses few sytem resources and has few dependencies, it is suitable for running in an HPC environment. It is useful as a fast and featureful text or code editor with syntax highlighting and window tiling without any special configuration.

Lite XL can, additionally, be extended with plugins using the plugin manager lpm which is preinstalled on compatible Vera nodes. In fact, it can be set up as a full-fledged IDE with support for modern features such as Language Server Protocol, making it a viable alternative to VSCode. A useful reference for plugins is the lite-xl-plugins repository.

For example, to install syntax highlighting for bash scripts you can open a terminal and run:

$ lpm install language_sh
Installing singleton plugin language_sh

Not all plugins available are kept up to date. If a plugin causes problems you can just remove it with lpm uninstall plugin_name.
