I don't really like the idea that for-each-ref reads _branch_ config. We could introduce the same set of keys but in color.for-each-ref namespace. %C(auto) will take care of the logic and choose the correct color key. When we replace branch's listing code with for-each-ref, I think we could somehow override for-each-ref keys with branch ones in-core.

Nope. --[no-]merged and --contains seem easy. show_detached is still WIP, mostly because detached HEAD may or may not show when you provide a pattern to git-branch (e.g. git branch --list 'foo*') and because HEAD is always the first item, regardless of sorting order. get_head_description also seems more porcelain-ish than a plumbing feature.. >> Another problem >> is the new "branch -v" seems to less responsive than old "branch -v" >> because (I think) of sorting, even if we don't need it. > > Does your track-responsiveness patch fix this?

I think we can change -v and -vv format slightly as long as the information remains the same. Nobody should ever parse these output with scripts. The color can be generated from color.branch.*. A bigger problem is show_detached(), --[no-]merged, --with and --contains. We need to move some of those code over to for-each-ref. Another problem is the new "branch -v" seems to less responsive than old "branch -v" because (I think) of sorting, even if we don't need it. I checked out your branch, made some more updates and pushed out to my for-each-ref-pretty again. Changes are: - fix segfault with "for-each-ref --format=%something refs/tags/' - add --pretty for new format syntax and keep --format unchanged - add --[no-]column to for-each-ref (for "git branch" with no arguments) - remove branch listing code and use for-each-ref instead (41 inserts, 378 deletes, beautiful). - add --sort and --count to git-branch -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I think it's documented as well as a known implementation limitation. It's not hard to be fixed (we could call format_commit_message again for all entries, this time with a single placeholder, to collect the best width). If anybody does need %>(*)%H to work, we could do it. BTW, the way I implement get_atom_width() is not really optimal. For n lines, we call print_value() in get_atom_width n^2 times. We could cache the calculated width instead and reduce that to n times. > Should we start off a new pretty-ref-formats document, where we > explicitly exclude things like %ae (because of the hex overriding > thing)? I don't think it's a problem if documented properly. And this one is doucmented as well, I think. I'd really like to introduce a new --pretty option (or something) that does not accept %xx as a hex notion, so %ae and friends won't be hidden. It's also a good thing for compatibility because currently %H in --format produces %H. After this, %H produces something else. It's unlikely that anybody has done that. But it's even better if we avoid that possibility entirely with a new option. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: [PATCH v2 0/3] Towards a useable git-branch
Oh, and by the way: We're pretty close we are to replacing branch -v and branch -vv. brv = for-each-ref --format='%(HEAD) %C(green)%<(*)%(refname:short)%C(reset) %<(*)%(objectname:short) %(subject)' refs/heads brvv = for-each-ref --format='%(HEAD) %C(green)%<(*)%(refname:short)%C(reset) %<(*)%(objectname:short) %C(blue)%(upstream:short)%C(reset) %(subject)' refs/heads There are small differences: 1. In branch -v, the green-color of the branch name is dependent on %(HEAD). Not worth ironing out, in my opinion. 2. In branch -vv, there are dependent square braces that come on when %(refname:short) is set. We might want to introduce an undocumented %(refname:branchvv) for internal use by branch -vv, for backward compatibility.

Re: [PATCH v2 0/3] Towards a useable git-branch
Hi Duy, I just woke up and started looking at the series: it's rather well done, and I'm confident that this is the way forward. To reciprocate, I've done some work at gh:artagnon/git for-each-ref-pretty. See: https://github.com/artagnon/git/commits/for-each-ref-pretty There is one major problem though: %>(N) doesn't work properly with f-e-r, and I'm not sure why. I'm not talking about your last patch where you compute * -- that works fine; it's just that %>(N) doesn't when N is a concrete number. Also, a couple of minor annoyances: 1. When f-e-r is invoked with refs/tags, we get stray output. Atleast it doesn't segfault, thanks to your ignore-commit patch. Maybe printing stray output is the right thing to do, as opposed to erroring out. 2. %>(*) only works with f-e-r atoms, not with pretty-format atoms. This is ofcourse obvious from the implementation, but isn't it a little consistent? Should we start off a new pretty-ref-formats document, where we explicitly exclude things like %ae (because of the hex overriding thing)?

I see that you've used format_commit_message(), but there are some concerns about pretty-formats conflicting with f-e-r's format. We'll iron it out slowly, but I like the overall approach. Thanks.

Check out https://github.com/pclouds/git.git for-each-ref-pretty It opens a hook in format_commit_message() to plug f-e-r's atom syntax in. I didn't do extensive test or anything, just t6300. The %xx syntax in for-each-ref might override some placeholders in pretty, I did not check. You can add extra %(xx) on top as you have done.

Definitely. I don't want to keep my ugly alias around forever, and I certainly want more users to have easy access to this (configurable git-branch output formats). However, the series is not the theoretical exercise of prettifying the code underlying -v and -vv. Supporting -v and -vv is something we _have_ to do to preserve backward compatibility, and I would consider it a side-effect of the series rather than the "aim of the topic". The aim of the topic is to get more useful output from git-branch. As long as the topic doesn't paint us into a corner after which it will be impossible to implement -v and -vv on top of the format, I think we're good. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

My apologies. After all, we have all been using 'git branch' for so many years without complaining. I only noticed the itch recently: it's a burning itch that I want it to be fixed very badly (hence the series). If anything I intended to convey the importance of the patch to me personally, not about some "general truth" on the broken-ness of git-branch.

By the way, I do not think "useable git-branch" is a good title, though. The expression has unnecessary venom in it, as if what it currently does is not usable. More flexible would be fine.

[PATCH v2 0/3] Towards a useable git-branch
So, while investigating alignment operators in pretty-formats, I found out that it's way too much effort and totally not worth it (atleast not immediately; we can add it later if we want). What I want now is a useable git-branch output. And I think I can say that I've achieved it. I currently have hot aliased to for-each-ref --format='%C(red)%(HEAD)%C(reset) %C(green)%(refname:short)%C(reset)%(upstream:trackshort)' --count 10 --sort='-committerdate' refs/heads and it works beautifully for me. Sample output: % git hot * hot-branch<> pickaxe-doc> publish-rev= publish-rev-test upstream-error= push-current-head= master= prompt= autostash-stash= rebase.autostash= The asterisk is red, the branch names are in green, and the tracking marker is white. I'm very happy with the implementation too: 1. color only kicks in at the parsing layer. 2. HEAD is a new atom. 3. :track[short] is a formatp like :short. There is no need to use a hammer and coerce everything into an atom, or throw everything out the window and start from scratch to conform to pretty-formats perfectly. Let's extend the existing format to be _useful_ sensibly. Thanks.
