Hi,
Several authors debated the plan to change the colons "::" in especially Carpet output file names to something else. One stated reason is the incompatibility of this and Windows, Samba and related systems, another is inconveniences these cause for MacOS users.
After considering several options we seem to converge on a replacement of "::" by "--" (double minus signs) as delimiter (see https://trac.einsteintoolkit.org/ticket/1338 for the full discussion).
This would, for example change a filename from
hydrobase::w_lorentz.maximum.asc
to
hydrobase--w_lorentz.maximum.asc
However small this change is, it would affect the vast majority of users. Thus, we would like to get feedback before actually going forward. So: if you like to have your opinion heard, now is the best time to accomplish that before it is "too late" (whatever direction it might be).
