**r.support - Need some way to access raster metadata.
Of the four sub-modules:
modhead -> r.region
modcats -> r.category
modcolr -> r.colors
modhist -> ???
The functionality built into the front-end module is mostly
non-interactive, and can be cannibalised.
So that just leaves editing the history. The obvious non-interactive
solution is a module (or two) which allows the history to be read from
or written to a text file.
r.support already allows non-interactive editing of most of the meta-data,
including history (r.support map history="xyz"), so wouldn't it be enought
to "just" disable the interactive functionality ?
modhist -> metadata
It's fundamental to maintain at a minimal level (this needs to be improved)
metadata of maps. Don't remove, please (the cmd line version).
I have salvaged the non-interactive portions of r.support.
It has three new flags to replace certain interactive yes/no prompts:
-s Update statistics (histogram, range)
-n Create/reset the null file
-d Delete the null file
I'll look into importing/exporting the history next.
BTW, should history and metadeta really be one and the same ? Shouldn't
they be separate ? Maybe extend the "description" to multi-line for
general descriptive meta-data and leave history for command history ?
And r.info should not call the history "comments", but "history".
Just a thought...
