Kia ora

Maybe I found a minor bug.

I have an extended elevation that includes a loop (many actually) and of course there is a gap in the loop as rendered that I would like to illustrate with a map-connection line.  Where the yellow shading is in the image below, I would like to draw a horizontal map-connection line.

So following the guidance in the Therion Book pages 105 and 106 I have created a scrap…

scrap 2-HawkesElevEXT-s1connection -projection extended -station-names []@2

  point 0 0   station -name 2.4 -from 2.5

  point 100 0 station -name 2.4 -from 2.3

  line map-connection

    0   0

   100 0

  endline

endscrap

On creating the scrap and before referencing it in any maps, Therion is unhappy and exits with the following:

#################### end of cavern log file ####################

done

calculating basic statistics ... done

processing extended elevation ... done

processing references ...

C:\Program Files\Therion\therion.exe: error -- string pointer is null

writing xtherion file ... done

Am using therion 6.2.0+fd5c1b6 (2024-01-10)

On experimenting a little, I realised that -station-names has no effect on the -from station parameter.

So this was my workaround…

scrap 2-HawkesElevEXT-s1connection -projection extended -station-names []@2

  point 0 0   station -name 2.4 -from 2.5@2

  point 100 0 station -name 2.4 -from 2.3@2

  line map-connection

    0   0

    100 0

  endline

endscrap

I’ll create an issue in GitHub.
