[PATCH] branch: colorize branches checked out in a linked working tree the same way as the current branch is colorized
In order to more clearly display which branches are active, the output of git branch is modified to colorize branches checked out in any linked worktrees with the same color as the current branch. This is meant to simplify workflows related to worktree, particularly due to the limitations of not being able to check out the same branch in two worktrees and the inability to delete a branch checked out in a worktree. When performing branch operations like checkout and delete, it would be useful to know more readily if the branches in which the user is interested are already checked out in a worktree. The git worktree list command contains the relevant information, however this is a much less frquently used command than git branch.

Re: [PATCH] branch: colorize branches checked out in a linked working tree the same way as the current branch is colorized
Will do re: screenshot when I get home, although it's pretty easy to imagine, the git branch output will have one other branch colored in green, bit without the asterisk (for one linked worktree) :) Also will do re: changing comments to /**/ (didn't know // was from C++, TIL) and I'll clean up the comments to remove some of the more obvious ones, but I'll try to keep a comment explaining the basic flow of creating a nest if statement to evaluate worktree refs for color. And yes, I copy/pasted into gmail. I was having trouble setting up send-email, but I think I may have it figured out now. Should I create a new thread with send-email? Or maybe reply to this one (I can do that by specifying the Message-ID to reply to right? This is my first time using this workflow, so I appreciate your patience :) )? Thanks for the feedback!

My first thought was "how do I know which branch I'm on then if they are all green?" but then the current worktree's branch would have a "*" in front while other worktree's do not. Perhaps worth mentioning in the commit message. It may be better though to have a different color code for other worktree's branch, we can still default the color to green, but people who rely on colors rather than "*" can choose a different color. -- Duy

I think the goal makes sense. Do we want to limit this to git-branch, though? Ideally any output you get from git-branch could be replicated with for-each-ref (or with a custom "branch --format"). I.e., could we have a format in ref-filter that matches HEAD, but returns a distinct symbol for a worktree HEAD? That would allow a few things: - custom --formats for for-each-ref and branch could reuse the logic - we could show the symbol (in place of "*") even when color is not enabled - it should be much faster if there are a lot of worktrees; your patch does a linear if/else chain to look at each worktree, and it does it in the format-language, which is much slower than actual C. :) Something like the patch below. I just picked "+" arbitrarily, but any character would do (I avoided "*" just to make it visually distinct from the current-worktree HEAD).

Re: [PATCH] branch: colorize branches checked out in a linked working tree the same way as the current branch is colorized
Thanks for the feedback Peff. I actually agree with all your points. I'd considered an approach like what you proposed, but rejected it for the first iteration in an effort to keep scope limited and see what kind of feedback I'd get overall (like would people even want this?). This is a much better approach, and also gives a path for listing the worktree path in the verbose output. @Duy yea we can use a different color, maybe a darker shade of green. I saw plenty to choose from in the color list so I'll play around with it. It would definitely make it easier to distinguish at a glance which branch is checked out in the current worktree vs others.

Great. If you go that route, feel free to use whatever bits of my patch are useful. I tested it only by running "for-each-ref" once, so it might need some more help. Definitely tests and documentation at the least. :) -Peff

But if we're open to change how branches are displayed maybe a config option like branch.format (probably not the best name choice) that can be set to the 'for-each-ref --format' syntax would be way more flexible. e.g. branch.format='%(if:equals=+)...' I think the different symbol and dimmed color would be a nice addition, but I am leaning towards giving the user the ultimate choice on how they want to format their output. (Maybe with dimmed plus symbol as default). -- Cheers, Rafael Ascensão

Yeah, I think that's reasonable, and would be enabled by the %(worktree) placeholder I showed. Just like we do something like: %(if)%(HEAD)%(then)* %(color:green)%(else) %(end) now, we could do: %(if)%(HEAD)%(then)* %(color:bold green) %(else)%(if)%(worktree)%(then)+ %(color:green) %(else) %(end)%(end) (respecting the user's color config, of course, rather than hard-coded colors). Trying that out, though, I'm not sure if we properly support nested if's. That might be a bug we have to fix first. > But if we're open to change how branches are displayed maybe a config > option like branch.format (probably not the best name choice) that can > be set to the 'for-each-ref --format' syntax would be way more flexible.

That might be a bug we have to fix first. Sorry, false alarm. I just had a typo in my format. This seems to work with the patch I posted earlier: git for-each-ref \ --format='%(if)%(HEAD)%(then)* %(color:bold green)%(else)%(if)%(worktree)%(then)+ %(color:green)%(else) %(end)%(end)%(refname)' \ refs/heads It sure would be nice if there was a way to insert line breaks without impacting the output. ;) -Peff

It would be really useful to (just via E-Mail to start) itemize the colors we use in various places and what they mean. E.g. I thought green here made sense because in "diff" we show the old/new as red/green, so the branch you're on is "new" in the same sense, i.e. it's what your current state is. But maybe there's cases where that doesn't "rhyme" as it were.
Re: [PATCH] branch: colorize branches checked out in a linked working tree the same way as the current branch is colorized
Not to hijack my own thread, but FWIW git branch -r shows remote branches in red, but old/new status of a remote branch is ambiguous (could have new stuff, could be out of date). Also, git branch -vv shows remote tracking branches in blue. One could argue it should be red since git branch -r is in red. But yea, probably best to take this topic to its own thread.

Under this interpretation red makes sense. On Thu, Sep 27, 2018 at 9:02 PM Ævar Arnfjörð Bjarmason wrote: > > E.g.

Because all these worktrees are in a sense active. They're checked out in some place. It's just the case that the particular one that we are in is probably more relevant than the others. -- Cheers Rafael Ascensão

The only comment I have is that I strongly suspect we will regret if we used an overly bland "worktree" to a rather narrrow "is this ref checked out in any worktree?" when we notice we want to learn other things that are related to "worktree". Other than that, very nicely done.

Having branch --format available, making an alias is a possible route. (Either by wrapping branch --format or for-each-ref itself). But I was referring to changing the output of the default $git branch;

Perhaps something like %(worktree-HEAD) would make more sense (the idea is that it is an extension of the existing %(HEAD) placeholder). Alternatively, %(HEAD) could return "*" or "+" depending on whether it's the current worktree head. That would mildly break an existing format like: %(if)%(HEAD)%(then) *%(color:green)%(end)%(refname) since it would start coloring worktree HEADs the same way. It would be rewritten as: %(if:equals=*)%(HEAD)%(then)...real HEAD... %(else)%(if:equals=+)%(HEAD)%(then)...worktree HEAD... %(else)...regular ref... %(end)%(end) I think that's perhaps nicer, but I'm not sure we want even such a minor regression. -Peff

Oh, you're right. I was thinking of the branch.sort we just added in v2.19. I agree that having branch.format (and a matching tag.format) would be useful. -Peff

I tend to think it is not worth having to worry about it by changing the meaning of %(HEAD) marking to save the effort to find a new token to fill that placeholder. Your %(worktreeHEAD) is good enough, I would think.

IIRC GitGitGadget has no facility yet to reply to any mail it did not generate itself (i.e. if you did not generate v1 using GitGitGadget, then it cannot generate a v2 that replies to the previous iteration). This might change at some stage, but I have other priorities for now. (Which should not stop any contributor from opening a PR to scratch their own favorite itch.)
