Hi Hazen:
Can you confirm you have been able to preserve all our svn history
(which includes our cvs history) in that git repository back to
revision 1? If so, that would be a very promising sign concerning the
quality of the svn2git conversion tool (or workarounds you used
for its conversion bugs).
I am more welcoming towards the idea of converting PLplot to a git
repository than previously. Thanks to many git recommendations like
yours, I do plan to start learning how to use git in the near future.
My one collaborator for the timeephemeris project (much less
complicated than PLplot) also prefers git, and because of his needs
and because I thought it was time to learn git I plan to switch that
project from svn to git in the next month or so and will presumably
learn git rather fast after that. So let's see how that goes, but
assuming that conversion and my practical use of git after that is a
success, then I would be willing to go along with a switch to git
later this year if our other PLplot core developers are willing to do
that as well.
I have just reviewed the subset of the svn commands that I ordinarily use with
PLplot
and other projects.
Those are
add
cat
checkout (co)
commit (ci)
copy (cp)
delete (del, remove, rm)
diff (di)
export
help (?, h)
log
move (mv, rename, ren)
propdel (pdel, pd)
propedit (pedit, pe)
propget (pget, pg)
proplist (plist, pl)
propset (pset, ps)
revert
status (stat, st)
update (up)
You don't have to do this to convince me since I am going to be
learning git regardless later this year, but it might help your case
with those developers here who are not familiar yet with git and are
wondering how painful using git is going to be to create a short
summary of how a developer would go about normal PLplot development in
a git world. I further suggest you keep that summary as simple as
possible (just giving the minimal git commands that do the equivalent
of the above svn commands) because one of the intimidating factors for
git is the large command set with large numbers of options. That
complexity makes git very powerful indeed, but also makes it
difficult/intimidating to learn.
