Does a mercurial subrepository have to be a subdirectory of the main repository?

Question

My project is made up of code in the following locations

C:\\Dev\\ProjectA
C:\\Lib\\LibraryB
C:\\Lib\\LibraryC

Presently each of these fold

Answer 1

You can indeed declare B and C subrepos of project A (they will appear as subdirectory, as described in Mercurial Subrepository).
That would improve your release mechanism as it would allow you to:

• get all repos in one place (A and under)
• reference an exact tag of B and C under A
• tag each sub-repo s first if they had any modification
• tag A with the information about B and C tags in it (any clone of A will be able to get the exact tags of B and C used by A)

You can also declare B as a subrepo of D, independently of A. What you make in A (regarding B) will have no consequences for B used in D.
