[Gretl-devel] function suggestion: copy to bundle

Hi, I've noticed that in a lot of hansl code many lines are spent on copying stuff into bundles, and I wonder if that could be made easier. What I have in mind is something like the function below, which would be called for example like this: copy2bundle(b, defbundle("m", mymatrix, "s", mystring, "m2", anothermatrix)) However, perhaps a built-in gretl function would be better and less clumsy. For example, the input wouldn't have to be wrapped in a transitory bundle and still the number of arguments to copy would be flexible. (BTW: 'getkeys' is not syntax-colored.) Opinions, endorsements? Thanks, sven ----- <hansl> function void copy2bundle(bundle *btarget, bundle bin)   n = nelem(btarget)   strings oldkeys = getkeys(btarget)   # easy approach first:   btarget = btarget + bin   # check if we missed something   if nelem(btarget) != n + nelem(bin)     # need to go into detail     matrix match = {}     strings inkeys = getkeys(bin)     loop i=1..nelem(inkeys) -q       loop j=1..nelem(oldkeys) -q         if inkeys[i] = oldkeys[j]           match |= i           break         endif       endloop     endloop     # process what we found (copy with overwrite)     loop k=1..nelem(match) -q       string s = inkeys[match[k]]       btarget["@s"] = bin["@s"]     endloop   endif endloop </hansl>
