[Therion] Not all maps exported in some circumstances

[Bruce]

Over the last couple of years I've noticed that I don't always get the maps
and surveys I expect to be included in my pdf outputs.  At long last I have
teased the problem enough to be reasonably sure of it's characteristics.

 

If I don't select any maps or surveys in my th-config file, then as I
understood it all the maps in my source files should be exported to pdf.
This was the meaning I took from the Therion book descriptions on page
45-46.

 

What I find is that if I have map objects defined that contain scraps AND
map objects defined that contain only centrelines (surveys), then the maps
that contain only surveys are NOT output unless they are explicitly
selected.  If the reference to the maps that contain scraps are commented
out, then the 'centreline maps' are suddenly output with out being selected.


 

I thought this was contrary to the Therion Book description, and not
behaviour that is particularly helpful.  If one has gone to the trouble of
defining a map with only a centreline or fixed points in it, then one would
presumably want it exported when nothing is explicitly selected (which by
default should select all).  If I didn't want the centreline output, I would
not have put it in a map object! To have Therion hide it can only cause
confusion I think.

 

So, I think now that I missed the subtlety in the following phrase.

"If there is no map selected, all scraps belonging to selected surveys are
selected by default for map export " as a map with no scraps is presumably
not exported (although in my experience it is if there are ONLY maps with no
scraps defined).

 

If this is what is going on, perhaps we could have a new compiler statement
like.

 

select all-maps

 

.to amend the current behaviour to select all maps (without having to select
them individually) that have being defined regardless of whether they have
scraps in them or not.

 

Or perhaps there is already a way to do this?
