vim Issues

If you see an error of the form:

Code Block
[]$ vim file.txt
E575: viminfo: Illegal starting char in line: ^I+^I26^I0
E575: viminfo: Illegal starting char in line: ^I+^I25^I0
E575: viminfo: Illegal starting char in line: ^I+^I24^I0
E575: viminfo: Illegal starting char in line: ^I+^I23^I0

Then your $HOME/.viminfo file has somehow become corrupt. To resolve, delete this file.

nano

GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to "emulate Pico as closely as is reasonable and then include extra functionality".

nano issues

We have noticed that some loaded modules (those that use ncurses) can cause nano to fail to open:

Code Block
[]$ nano
Segmentation fault (core dumped)

The editor works on a clean environment on the login nodes (i.e. with no modules loaded).

Currently this is unfortunately not a problem we can simply resolve, and suggest running multiple sessions, one simply for nano and the others for testing/computation.

emacs

emacs is a full-featured editor comparable with vim, but without insert and editor/command modes. Instead, commands are identified by special characters (combinations of the Control and/or Meta keys with regular characters), and regular text is treated as text being added to the document. It also has additional features designed for editing source code and can be customized and used as an IDE for coding with integrated compiling and debugging. There are several tutorials online as well. The University of Chicago has done a great job on explaining what emacs is and how to use it:
