[GRASS-dev] G7: Definition problem in parser_standard_options.c

[Markus Neteler]

Hi,

I just discovered that local modifications of predefined
parser variables influence the help text/manual/etc:
Example:


http://grass.osgeo.org/grass70/manuals/r.resamp.interp.html
...
method=string
    Sampling interpolation method
    Options: nearest, linear, cubic, lanczos
    Default: linear
    nearest: Nearest-neighbor interpolation
    linear: Linear interpolation
    cubic: Cubic interpolation
    ...      <<-- missing: lanczos


because of
lib/gis/parser_standard_options.c

   case G_OPT_R_INTERP_TYPE:
        Opt->key = "method";
        Opt->type = TYPE_STRING;
        Opt->required = NO;
        Opt->description = _("Sampling interpolation method");
        Opt->options = "nearest,linear,cubic";
        G_asprintf((char **) &(Opt->descriptions),
                   "nearest;%s;linear;%s;cubic;%s",
                   _("Nearest-neighbor interpolation"),
                   _("Linear interpolation"),
                   _("Cubic interpolation"));
        break;

Besides copying manually the G_asprintf() stuff into the module (no
good), is there a better way of implementing it?
