In principle correct, at some point the openSUSE community agreed to use 
only the version number for the repository name for Leap.
But 'openSUSE_Leap_X.Y' should also work, of course.

No problem. Currently the differences between the individual Leap 
versions and Tumbleweed are very small, look for '%if 0%{?suse_version} 
...' in the original gambas3.spec file.

As already written several times, the rpm-spec format is very flexible 
and powerful, so that it is almost never the case that separate spec 
files are needed for each distribution.

Right now you can use (copy) the gambas3.spec for all openSUSE flavors, 
it already works (as noted above: look for '%if 0%{?suse_version}' when 
searching for differences).

Only two versions are actually relevant: Leap 15.6 and Tumbleweed. 15.5 
is EOL end of the year, 16.0 is coming next year and maybe Slowroll 
could still be interesting.

gambas3-openSUSE_Leap_15.6.spec
gambas3-openSUSE_Tumbleweed.spec
gambas3-openSUSE_Slowroll.spec (?!)
