I think stuff like multiple delimiters should have been dealt with before, as the right place to insert the ndmin code (which includes the decision to squeeze or not to squeeze as well as to add additional dimensions, if required) would be right at the end before the 'unpack' switch, or rather replacing the bit:
if usemask: output = output.view(MaskedArray) output._mask = outputmask if unpack: return output.squeeze().T return output.squeeze()
But there it's already not clear to me how to deal with the MaskedArray case...
Oh, easy. You need to replace only the last three lines of genfromtxt with the ones from loadtxt (808-833). Then, if usemask is True, you need to use ma.atleast_Xd instead of np.atleast_Xd. Et voilà. Comments: * I would raise an exception if ndmin isn't correct *before* trying to read the file... * You could define a `collapse_function` that would be `np.atleast_1d`, `np.atleast_2d`, `ma.atleast_1d`... depending on the values of `usemask` and `ndmin`... If you have any question about numpy.ma, don't hesitate to contact me directly.
