1.2 Jag: Terminal Editor With Mouse Support and Colour Highlighting

Jag

jag is a terminal editor that is compatible with Mac OS and Linux. It is basically the same editor as the one that is currently embedded in LispE.

jag offers:

• mouse support
• color highlighting for many languages (C++, python)
• regular expressions to search and replace
• undo/redo mode (ctrl-u / ctrl-r)

The editor is pretty small and comes with a multitude of options:

Commandes :
   	- Ctrl-k: delete from cursor up to the end of the line
   	- Ctrl-d: delete a full line
   	- Ctrl-u: undo last modification
   	- Ctrl-r: redo last modification
   	- Ctrl-f: find a string
   	- Ctrl-n: find next
   	- Ctrl-g: move to a specific line, '$' is the end of the code
   	- Ctrl-l: reload file from disk
   	- Ctrl-t: reindent the code
   	- Ctrl-h: local help
   	- Ctrl-w: write file to disk
   	- Ctrl-c: exit the editor

   	- Alt-x: cut mouse selection
   	- Alt-c: copy mouse selection
   	- Alt-v: paste mouse selection

   	- Ctrl-x: Combined Commands

LispE Internal Regular Expression Description

About mouse copy/paste

When the editor is in mouse mode, you must use alt-X, alt-C and alt-V to cut, copy and paste the selection. This selection copies the selected strings into an internal clipboard, which is different from the system clipboard. You can still copy from the system clipboard. However, if you want to cut/copy to the system clipboard, you must deactivate mouse mode first, with Ctrl-X m. You can return to mouse mode with Ctrl-X m again.
