Cactus is a super lightweight text editor I made in C. It supports syntax highlighting for .c and .cpp files.

Should I use this

No. It actually doesn't work all that well. You can write in it, but as far as I know, there is no indentation.

Saving files does not actually work either. Also there are so many bugs.

What if I just want to run it and see

Okay cool. So if you have C compiler, just make all with the makefile and then use ./cactus to run the editor.

If you have a C or C++ file that you want to open with the editor, run ./cactus file_name.c or whatever.

I just wanted to see try to see if I could get somewhere and I think I did. This is all command line based.
