17.2 Environment Variables

The following environment variables can be set to override some default settings in GPS:

GPS_ROOT

Override the default root directory specified when GPS is built (during the configure process, see the file INSTALL in the GPS sources for more details) to access information such as the location of the translation files.

GPS_HOME

Override the variable HOME if present. All the configuration files and directories used by GPS are either relative to $HOME/.gps (%HOME%\.gps under Windows) if GPS_HOME is not set, or to $GPS_HOME/.gps (respectively %GPS_HOME%\.gps) if set.

GPS_DOC_PATH

Set the search path for the documentation. See Adding New Help Files.

GPS_CUSTOM_PATH

Contains a list of directories to search for custom files. See Customizing through XML and Python files for more details.

GPS_CHANGELOG_USER

Contains the user and e-mail to use in the global ChangeLog files. Note that the common usage is to have two spaces between the name and the e-mail. Ex: "John Does <john.doe@home.com>"

GPS_STARTUP_PATH

Contains the value of the PATH environment variable just before GPS was started. This is used by GPS to restore the proper environment before spawning applications, no matter what particular directories it needed to set for its own purpose.

GPS_STARTUP_LD_LIBRARY_PATH

Same as GPS_STARTUP_LD_LIBRARY_PATH but for the LD_LIBRARY_PATH variable.

GPS_MEMORY_MONITOR

If set, GPS will add special code on every allocation and deallocation, thus slowing things down a bit, that makes it possible to check where the biggest amount of memory is allocated, through the GPS.debug_memory_usage python command.
