AHELP for CIAO 4.11 ChIPS v1

chipsrc

Context: chips

Synopsis

The .chips.rc file provides user-configuration options for ChIPS

Description

When ChIPS is started - either directly by the "chips" command or from another CIAO application such as Sherpa - it processes a resource file that defines the default behavior for the ChIPS commands and can be customized to the user's preferences. The default location for this resource file is $HOME/.chips.rc but this can be overridden when starting ChIPS using the -rcfile command-line flag ("ahelp chips").

Setting and retrieving preferences

The set_preference and set_preferences commands change the preference settings of the ChIPS server, the get_preference and get_preferences commands return them.

Saving and loading preferences

The save_preferences command writes out the current preference settings and load_preferences reads them in.

The GUI preferences

The GUI preference settings (gui.*) can be read and set using the routines discussed above but they can also be changed directly from the GUI, using "Edit/Gui Configuration" menu item.
