Editing .octaverc

The .octaverc file is the octave [https://en.wikipedia.org/wiki/Configuration_file configuration file] on Linux that resides in the user's home directory (~). It has basically the same role as startup.m in Matlab - you might want to soft link startup.m and .octaverc to avoid duplication. Many basic settings can be put here. Further information is given in the [https://www.gnu.org/software/octave/doc/interpreter/Startup-Files.html documentation].


Some handy examples of configuration options are given below, as well and on the [[Tips_and_tricks|Tips and tricks]] page.

* '''edit mode async''' ''# make spawned processes run in background''
* '''EDITOR('gvim > /dev/tty 2>&1 < /dev/tty %s')''' ''# use gvim as the default editor''
* '''more off''' ''# scroll screen output automatically''
* '''history_control ("ignoredups");''' ''# ignore duplicates in command history''
* '''crash_dumps_octave_core(0);''' ''# never dump octave-core''
* '''sigterm_dumps_octave_core(0);'''
* '''sighup_dumps_octave_core(0);'''
* '''set(0,'defaultfigurecolormap',gray(256));''' ''# set colormap to gray(256)''
* '''suppress_verbose_help_message(1);''' ''# use concise form for help''
* '''page_screen_output(0);''' ''# write text to screen without buffering''
* '''warning("off","Octave:divide-by-zero");''' ''# disable unwanted warning messages''
* '''warning("off","Octave:possible-matlab-short-circuit-operator");


The behaviour of the command line cursor in Octave is controlled by a separate codebase (readline), which has its own configuration file (.inputrc). Examples of useful entries in this file are given below and in ''??need a good reference for readline options??''.

* '''set blink-matching-paren off''' ''# prevent blinking parenthesis matching''
