Extase is a modern, lightweight terminal-based text editor engineered from the ground up in pure C. It is built with a zero-dependency philosophy, avoiding libraries like ncurses in favor of the raw POSIX terminal API.
Extase is currently compatible with all modern POSIX systems, with native Windows support on the roadmap.
Because Extase relies purely on the POSIX standard with no external dependencies, building it is fast and straightforward. You only need a C compiler (GCC or Clang) and Make tool.
First, download the repository from github
git clone https://github.com/alechiozza/extase.git
Then, compile it with
cd extase
make
(Optional) You can install extase globally on your system with
sudo make install
Or uninstall it with
sudo make uninstall
To run the editor, you just need to type
extase <filename>
