3.1 The Help Menu 3.2 Adding New Help Files
By default when you start GPS, the working area contains a help window
displaying HTML help files. On-line help for the GNAT tools is available
from the Help
menu item.
Since HTML pages can contain lots of complex information, resizing the
help window can take some time, making the user interface less responsive.
It is therefore recommended to close the Help
window
when not using it. You can reopen this window at any time using the
Help
menu item.
For the best use of the integrated help, it is recommended to load small HTML pages each time instead of long pages which will be slow to load and display.

This menu contains a number of additional entries, depending on what documentation packages were installed on your system. See the next section to see how to add new help files.
The help window also provides a contextual menu that gives the possibility to copy the current selection to the clipboard.

GPS_DOC_PATH
(a colon-separated list
of directories on Unix systems, or semicolon-separated list of
directories on Windows systems). In addition, the
default directory <prefix>/doc/gps/html
is also searched. If the
file cannot be found in any of these directories, the corresponding
menu item will be disabled.
The environment variable GPS_DOC_PATH
can either be set by each
user in his own environment, or can be set system-wide by modifying
the small wrapper script `gps' itself on Unix systems.
It can also be set programmatically through the GPS shell or any of the scripting languages. This is done with
GPS.add_doc_directory ("/home/foo") |
The specific list of files shown in the menus is set by reading the
index files in each of the directories in GPS_DOC_PATH
. These
index files must be called `gps_index.xml'.
The format of these index files is specified in see section 15.4.16 Adding documentation.
