I think that the way it represents my name in commit messages is user configuration, as would be the behaviour of `git-commit PATH'. Environment variables almost work for this, but they're a nuisance to change. This stuff ought to be somewhere in my home directory, probably; though it would be useful to override temporarily, or on a per-repository basis. * Project configuration: how GIT should be supporting a particular project. The merge.summary flag is like this, I think: whether to have summaries in merge messages is a policy decision to be taken for a whole project, rather than something to be left to the whims of individual developers. Such settings probably to be propagated through git-clone, git-fetch and so on. * True repository configuration: how this particular repository ought to behave. I can't think of many examples off the top of my head, but core.repositoryformatversion and core.filemode are the sorts of things I'm thinking of. I'm not entirely sure where I'm going with this at the moment, and I don't like some of the complexity which seems inherent in doing anything about it, but I thought I'd stick my oar in anyway. -- [mdw] ``` ## Junio C Hamano, 2006-02-12 18:56 Subject: Re: Configuration file musings Message-ID: <7v4q34be2z.fsf@assigned-by-dhcp.cox.net> URL: https://gitlist.dev/e/7v4q34be2z.fsf%40assigned-by-dhcp.cox.net In-Reply-To: ``` Mark Wooding writes: > Having thought about things a bit, I've reached the conclusion that the > configuration file $GIT_DIR/config is trying to hold (at least) three > entirely different kinds of configuration. Yes. I've been somewhat bothered by that, but I did not ramble on it too much because I could not say what exactly is _wrong_ to have these things in the same file. Except perhaps that pure user configuration could be further split out from per-repository user configuration to .gitconfig under $HOME or something like that. The former is things like "I am Junio C Hamano no matter which project I work on" the latter is for example "The e-mail address I use for this project is ". But once we start dealing with more than one configuration file, you need one file taking precedence over the other and it appeared there is no single _right_ order. The above identity case is an example that it is better to make the config in repository to override $HOME one, but if you think long enough I am sure you can come up with an example that you would want to override repository one from $HOME one. ```
