Re: Repository conversion

[Clark G. <cla...@fa...>]

I would certainly agree that git is apparently more prevalent than hg but both have reasonable critical mass. I wouldn't be concerned about the vitality of either. I would suggest those who are interested do a real comparison relative to how you want the project to work, and do so with an open mind relative to your preferred default.

For example one thing git does well is manage changes that do not respect file structure, whereas hg considers the file to be the artifact that is managed. I think in gnuplot the latter is consistent with how we think of the code base, but git's perspective is interesting.

I asked my most "worldly" developer to assess the two for my team's purposes. Joel Sposky's blog posts on distributed code management and his hginit.com site were also illustrative. And we decided on hg. The more seasoned devs in the group have enjoyed this decision and the ops guys live with it well (they certainly would not be more at home with git).

But in my day job I do not have to concern myself too much with the inconvenience of consensus. ;-) YMMV.

With that said, do check out Joel's post and hginit.com.

Cheers
Clark
