You seem to assume it's the one that maintains the symlink, but why is that assumption true? The backend is determined for certain operations. Did you make sure all of them will indeed want the backend of my-repo and not the other one.

I agree that this assumption is quite controversial even for myself -- it depends on what this function is used for. Adding an option may be the best way to resolve it. > And what is the semantics of such a situation, anyway? For example, one may manage the home directory configuration with one type of VC. For configuration files for some applications, she may rarely use them, so she simply cloned/checked out someone else's configuration using a different VC, and symlink the file in the home dir to the actual configuration file. Another example: one may have a repository that contains files linking to non-tracked files -- create a repository that link to common configuration files such as the ones in /etc for easier management.

Can we avoid trying the 2nd search by detecting that the truename and the original name specify the same file? Or maybe by detecting the file types that could justify the second search in the first place? ^ permalink raw reply [flat|nested] 31+ messages in thread

I don't see how find-alternate-file can be used here. It would open the file (or directory) than is the true name of the currently visited file (or directory), and kill the previous buffer. vc-responsible-backend would be called with the true name automatically. This is close to what vc-follow-link does already. But if that's definitely not what you want, how about a command like this?

OK, I think I have screwed it up. vc-responsible-backend looks like a function mainly provided for elisp programming purpose, which people can make use in their own customization. Thus, none of these functions should be used. Instead, file-truename or file-chase-links should be used.

GNU coding standards frown on using "path" for anything that isn't a PATH-style list of directories. We use "file name" instead, but in this case you don't need even that: just say "the given @var{file}". > For example, if @code{emacs.c} is a emacs.c is a file, so it should have the @file markup, not @code. > +file tracked by git, @code{(vc-responsible-backend "emacs.c")} returns > +@code{"Git"}. ^^^^^^^^^^^^ You want @samp{Git} here, without the quotes. The quotes might mislead someone into thinking the result is a string.
