[git question] how to handle few projects with common parts?

[Ivan Dimitrov]

Hi list,
Maybe my question relates rather to configuration management, but it
is over GIT.
In short - I have to manage two projects with 95% same files
(components) and all the rest are platform depended. I am trying to
keep different platforms in different branches, but I can't figure out
how keep the common part of the project synchronized?

Are the other files (1) *completely* different across branches, or (2)
the same in each branch, but customized?

If (1), I don't think branches are the answer.  You probably just want
a subdir per platform and a simple config file that points at which
branch to use.  Or maybe use some #ifdefs, or whatever the equivalent
is in your system.

If (2), perhaps what you want is three branches: a main development
branch, and two customized branches that you merge (or rebase) master
into.  I do this sometimes when I want a "development" branch and then
some specific customizations for a particular production deployment.
(eg. a default config file and the "live" config file, and I want both
to be version controlled separately)

Have fun,
