From d48034551a3b1cb2dc60ff1c30a2d5acad20b6a1 Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Thu, 22 Jun 2017 14:01:49 -0700 Subject: submodules: overhaul documentation This patch aims to detangle (a) the usage of `git-submodule` from (b) the concept of submodules and (c) how the actual implementation looks like, such as where they are configured and (d) what the best practices are. To do so, move the conceptual parts of the 'git-submodule' man page to a new man page gitsubmodules(7). This new page is just like gitmodules(5), gitattributes(5), gitcredentials(7), gitnamespaces(7), gittutorial(7), which introduce a concept rather than explaining a specific command.

The other repository has its own history, which does not -interfere with the history of the current repository. This can be used to -have external dependencies such as third party libraries for example. - -When cloning or pulling a repository containing submodules however, -these will not be checked out by default; the 'init' and 'update' -subcommands will maintain submodules checked out and at -appropriate revision in your working tree. - -Submodules are composed from a so-called `gitlink` tree entry -in the main repository that refers to a particular commit object -within the inner repository that is completely separate. -A record in the `.gitmodules` (see linkgit:gitmodules[5]) file at the -root of the source tree assigns a logical name to the submodule and -describes the default URL the submodule shall be cloned from. -The logical name can be used for overriding this URL within your -local repository configuration (see 'submodule init'). - -Submodules are not to be confused with remotes, which are other -repositories of the same project; submodules are meant for -different projects you would like to make part of your source tree, -while the history of the two projects still stays completely -independent and you cannot modify the contents of the submodule -from within the main project. -If you want to merge the project histories and want to treat the -aggregated whole as a single project from then on, you may want to -add a remote for the other project and use the 'subtree' merge strategy, -instead of treating the other project as a submodule. Directories -that come from both projects can be cloned and checked out as a whole -if you choose to go that route. +For more information about submodules, see linkgit:gitsubmodules[7].
