When I started publishing my first Vim plug-ins I would prepare ZIP archives for Vim Online using makefiles. The makefiles would make sure the miscellaneous scripts were included in the uploaded distributions. This had two disadvantages: It lost git history and the repositories on GitHub were not usable out of the box, so [I got complaints from GitHub (Pathogen) users] [github-complaints]. + +2. My second attempt to solve the problem used git submodules which seemed like the ideal solution until I actually started doing it. Submodules are not initialized during a normal `git clone`, you need to use `git clone --recursive` instead but Vim plug-in managers like [Pathogen] [pathogen] and [Vundle] [vundle] don't do this (at least [they didn't when I tried] [vundle-discussion]) so people would end up with broken checkouts. + +3. After finding out that git submodules were not going to solve my problems I searched for other inclusion strategies supported by git. After a while I came upon the [subtree merge strategy] [merge-strategy] which I have been using for more than two years now. + +## Compatibility issues + +Regardless of the inclusion strategies discussed above, my current scheme has a flaw: If more than one of my plug-ins are installed in a Vim profile using [Pathogen] [pathogen] or [Vundle] [vundle], the miscellaneous autoload scripts will all be loaded from the subdirectory of one single plug-in. + +This means that when I break compatibility in the miscellaneous scripts, I have to make sure to merge the changes into all of my plug-ins. Even then, if a user has more than one of my plug-ins installed but updates only one of them, the other plug-ins (that are not yet up to date) can break (because of the backwards incompatible change). + +The `xolox#misc#compat#check()` function makes sure that incompatibilities are detected early so that the user knows which plug-in to update if incompatibilities arise. + ## Contact If you have questions, bug reports, suggestions, etc. the author can be contacted at <peter@peterodding.com>.
