ANTLR postscript tree

With antlr4 TestRig you can use -ps to generate a PostScript tree. I can't view my tree.

PostScript:

%!PS-Adobe-3.0 EPSF-3.0
%%BoundingBox: 0 0 54 48

0.3 setlinewidth
%% x y w h highlight
/highlight {
        4 dict begin
        /h exch def
        /w exch def
        /y exch def
        /x exch def
        gsave
        newpath
        x y moveto
        0 h rlineto     % up to left corner
        w 0 rlineto     % to upper right corner
        0 h neg rlineto % to lower right corner
        w neg 0 rlineto % back home to lower left corner
        closepath
        .95 .83 .82 setrgbcolor
        fill
        grestore
        end
} def
/ArialMT findfont 11 scalefont setfont
27,662 32,395 moveto
12,616 15,395 lineto

Bon, c'est bien simple, il semble que ANTLR 4 génère les chiffres en fonction de la locale, c'est-à-dire, en français : avec une virgule. Et c'est dommage, parce dans ce cas, PostScript n'en trave que dalle.

The solution to you problem is simple. It seems that ANTLR 4 generates numbers using the locale, i.e. in French, using a comma. It's a pity because PostScript does not understand french (latin?) floating numbers.

You should fill a but report to ANTLR 4.

On Unix, you can temporarily change the locale on bash

export LANG=C
