Kate is a multi-document, multi-view text editor for KDE. Very well adapted to octave. Features syntax highlighting, embedded terminal, and much more.


Syntax highlighting[edit]

Either Matlab or Octave syntax highlighting for m-file can be chosen in

Tools/Mode/Scientific menu

The default for *.m files can be defined to be octave by going to

Settings/Configure kate/Editor Component/"Open/Save"/Modes & filetypes

and setting Priority 0 for Filetype : Scientific/Matlab and Priority 1 for Filetype : Scientific/Octave (the important being that it is higher than the Matlab one)

Comment/uncomment[edit]

Kate can comment/uncomment several lines of code at the same time. Simply select the lines and press Ctr+D to comment and Shift+Ctr+D to uncomment.

For the current default (april 2012, octave.xml version 1.01), the added comment start at the beginning of the line.

In order to have the # to begin like the indented text, just patch /usr/share/kde4/apps/katepart/syntax/octave.xml. First save the following file in /tmp for instance

File: kate_highlight_octave.xml.patch

The last change is not relevant for the comments.

Quit kate, then, as root, cd /usr/share/kde4/apps/katepart/syntax/ && patch -p7 --backup < /tmp/kate_highlight_octave.xml.patch

Embedded terminal[edit]

Integrates a terminal to the editing window.

Settings/Configure kate/Application/Plugins/Terminal tool view

(by the way, you can select also the Find in file tool, quite handy)

Then the terminal can be hidden/shown by clicking on the corresponding button at the bottom of the window.

multiple terminals[edit]

It is possible to switch between several terminals using screen. Right click on the terminal / configure current profile / Command =>

/bin/bash -c screen

Then create a new session by Ctr+a c (which means hold Ctrl, hit a then c).

To go to previous session : Ctr+a p.

To go to next session : Ctr+a n.

To go kill current session : Ctr+a k.

set EDITOR to kate[edit]

On the command line, or in your ~/.octaverc, add the line EDITOR("kate %s") then typing in octave edit myfunc will open myfunc.m in the current kate session
