[mapserver-users] Mapfile comment parsing issue

[Julian Hollingbery]

Hi list,

I have observed an obscure behavior in MapServer version 7.0.7, which I’d like to run by you before I submit an issue.

I have an issue where labels on contour line disappear when I write a particular type of comment after the TEXT directive.

Using this request:
http://host/fcgi-bin/mapserv.fcgi?map=ms_issue_report.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=542400.00,6216800.00,542600.0,6217000.0&CRS=EPSG:25832&WIDTH=400&HEIGHT=400&LAYERS=dhm_kote_0_5_m,dhm_kurve_0_5_m&STYLES=&FORMAT=image/png&TRANSPARENT=FALSE
this piece of MAP file

   CLASS
     GROUP "default"
     NAME "dhm2015 kurver, 0,5 m"

     TEXT (tostring([hoejde],"%.2f")) #altid to decimal, også .00 (eng. always two decimals, including .00)
     STYLE
       OPACITY 80
       COLOR 100 50 0
       WIDTH 1
     END #STYLE
      LABEL
        FONT "arial"
        SIZE 9
        COLOR 137 90 68
        OFFSET 0 -6
        SHADOWSIZE 1 1
        TYPE TRUETYPE
        REPEATDISTANCE 300
        ANGLE auto
        PARTIALS FALSE
      END # LABEL
   END #CLASS

Gives me https://pasteboard.co/I6jsBen.png (contour lines w/o labels), whereas

   CLASS
     GROUP "default"
     NAME "dhm2015 kurver, 0,5 m"
     #altid to decimal, også .00 (eng. always two decimals, including .00)
     TEXT (tostring([hoejde],"%.2f"))
     STYLE
       OPACITY 80
       COLOR 100 50 0
       WIDTH 1
     END #STYLE
      LABEL
        FONT "arial"
        SIZE 9
        COLOR 137 90 68
        OFFSET 0 -6
        SHADOWSIZE 1 1
        TYPE TRUETYPE
        REPEATDISTANCE 300
        ANGLE auto
        PARTIALS FALSE
      END # LABEL
   END #CLASS

Results in https://pasteboard.co/I6js9YK.png (which is the desired result: Contour lines labelled with two decimal points).
I have narrowed it down a bit, and if I delete the “(eng. ..)”, i.e. just have
     TEXT (tostring([hoejde],"%.2f")) #altid to decimal, også .00
It still works nicely.

So I guess the parentheses are somehow parsed as something meaningful (related to the “tostring”-expression, perhaps?), invalidating the TEXT declaration.

Has anyone seen something similar?

Best Regards
