git - Common code between two projects (repos?) -

i know has been asked in 1 way or before, haven't found answer answer problem.

i have 2 codebases , b (aimed @ different platforms) sharing of code. let's call shared code part c.

what i'd have repo(s?) setup in way can commit changes part c a, , pulling b me changes made c residing in , other way around.

for example, consider dir structure:

a | |-- a.txt |-- common.txt  b | |-- b.txt |-- common.txt 

if make changes a/common.txt , pull b want changes made a/common.txt present in b/common.txt

thanks

you should consider using git submodules.

the thing mention, probably, better off making changes in different folder, pushing commits server and, finally, pulling code bases submodules.
