This patch cleans up the calling convention between lib/gis/parser.c and
lib/gis/gui.tcl. It extends general/g.parser/main.c to cover all of the
string attributes available via the c interface. It adds a new char *
guisection attribute to options and flags in include/gis.h.
Flag and module attributes are now passed from lib/gis/parser.c to
lib/gis/gui.tcl as the flattened list form of a tcl array, just like the
attributes for options.
I moved GUI logic regarding text to use for labels (label or description) from
lib/gis/parser.c to lib/gis/gui.tcl. This will allow a gui to decide, for
example, to display the description text as "tooltip" or balloon help when an
option has a label.
general/g.parser/main.c now parses all of the char* module, option, and flag
attributes from the #% notation, including the new guisection attribute
I added a new char* guisection attribute to struct Option and struct Flag.
This is a string that arranges the options and flags into a tree hierarchy to
allow for more organized user interfaces for commands with many options. This
has not been implemented anywhere else yet. It contains the full tree path
for where to place the option or flag, delimited by the ';' character. For
programs with very options inputs this should remain null or be "". For
example, an option for an input map might have just "Inputs" and an option
for the learning rate for perceptrons in a neural network classification
program might be "Neurons;Perceptrons". Examples of how this could be used in
layout were discussed in the thread "GUI sections and metadata or history
These changes pave the way for work on more interesting or friendly generic
user interfaces to the commands that make up the bulk of grass.
