r.mapcalculator: variable number of input maps
|Pull Request or Patch supplied:||No||Resolution:|

It would be good to have a variable number of input maps for r.mapcalculator GRASS module. See r.buffer as an example (this approach cannot be used directly, as the underlying GRASS commands are different).
#1 Updated by Markus Neteler almost 10 years ago
The reason for the different behaviour is that the command style is different:
r.mapcalculator [-eo] [amap=string] [bmap=string] [cmap=string] [dmap=string] [emap=string] [fmap=string] formula=string outfile=string ...
r.buffer [-zq] input=name output=name distances=value[,value,...] ...
The distances parameter is a 1..n list while in r.mapcalculator the
parameters are separate.
Suggestion: modify r.mapcalculator in QGIS to require input=string[,string,...]
since this cannot be changed in the GRASS 6 series for compatibility.
