Git Gui - enhancement suggestion - Can a double click on the file name in the “unstaged” area move the item to “staged changes”

Git Gui - enhancement suggestion - Can a double click on the file name in the “unstaged” area move the item to “staged changes”

[Allan Ford]

Dear Git Authors,



Not a bug, but a suggestion consideration for “Git Gui”


Can a double click on the file name in the “unstaged” area move the
item to “staged changes” .. (rather than having to click on the small
icon to the left of the file name?)


cheers, Allan

It has been something on my radar for some time. Shouldn't be something 
too difficult to do.

While I like the idea in general, I have a question that I'd like to ask 
other git-gui users:

If we implement something like this, what happens when you single-click 
on the icon? Do we treat that as a stage/unstage command? If we keep the 
legacy behaviour of single-click on the icon stages/unstages, then a 
part of the row is single-click and the rest double-click.

If we make an entire row of the stage/unstage widget double click, it 
messes with people who are already used to it.

Is partial single and partial double click behaviour acceptable? Or 
should we make the entire row double click only? Or something else that 
I missed?

I consider adding a second way as not not acceptable. I also consider
double-click on a file in a GUI an "open" action. But in git-gui, this
"open" action (showing the diff) is already done with a single-click.

From my point of view, it can stay as is.

Bert

The way I see it, there are two parts.

Objectively, it is harder to click the icon than it is to click anywhere 
on the entire row. The small size of the icon adds to the problem.

Subjectively, I personally came from using Atom for quite a while, and 
it staged the file on double click. I think some other editors do this 
too. So, I was used to that way of doing things, and had to adapt to the 
git-gui way.

Well, that's the other point of view, and it makes sense too. As I was 
afraid, this seems to be a personal preference problem and it will be 
difficult to reach agreement. And I'm generally inclined to keep things 
like they are rather than making drastic changes with debatable benefit.

How about something in the middle? How about larger icon sizes? Will 
that help your workflow Allan?

I've always felt this was a bit of user-experience failure on git-gui's 
part.  Single-click should not behave differently just because you click 
the icon.  I've seen many new git-gui users find this (mildly) confusing.

I'd be happy if the click behavior was consistent across the entire row: 
single-click to select, double-click to stage/unstage, and there's 
nothing special about clicking the icon.  I personally don't think it 
would be hard to adjust to that.

I guarantee you that if double-click support is added while preserving 
the icon-single-click, users will get tripped up when they double-click 
the icon and accidentally stage two files.

I don't mind adding the suggested double-click action, but removing the
single-click action would be a step backward IMO.

I acknowledge that consistency is an important aspect of GUI design.
Particularly for new and/or low-competency users. But surely
efficiency must also be valued too. Repetitive strain injury is not
nice. I have some days where I have hundreds or possibly even
thousands of such single clicksto stage and unstage items. Currently
it is possible to review and accumulate them efficiently due to how
that pane responds.

And this seems a very small aspect to learn. if a person is so
"confused" by such a small thing to learn, I wonder what hope they
would have to comprehend git itself.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Please, no.

I can't say it strongly enough. Please do not change stage/unstage
to require double-click. This would be most unwelcome here, unless it
comes with a configuration option to preserve the old behaviour.

Maybe the actual problem is that the present icon (perhaps surprisingly)
has the behaviour of a blank check-box that relocates. I don't wish for
any change, but if the desire for change is irresistable then the
simplest solution is for the icon (that appears to the left of filenames
in the unstaged pane) to be replaced with blank check box that
behaves exactly as the current icon does. That is:
When clicked, it becomes a checked-box alongside the filename in
the staged area. And if that staged-checked-box is clicked, it reverts to
an unchecked-box (instead of the icon) in the unstaged pane.

No problem here, but see my other message for further thoughts.

Yes!

In fact, I've often fantasized how useful it would be that if I double
clicked on that file name in the unstaged pane or the staged pane,
then that would open the file for editing in my preferred/configured editor.

Now for me *that* would be a very frequently used improvement!

I wonder what other readers think about this idea?

Sounds reasonable. I've wanted something similar, but for commit 
messages.

But one major reason I didn't come up with a patch for editing commit 
messages in the editor of your choice is terminal based editors. I don't 
think there is any way of finding out the default terminal emulator in 
Linux, and I don't think there is a standard way of making terminal 
emulator launch programs you want.

So your suggestion works only for GUI based editors. We would have to 
mention that only GUI based editors can open files.

I like the idea, but I thought I'd point a problem I saw with this 
feature.

Also, the file viewer in git-gui opens the blame viewer, but I suppose 
that's not what most people want.

Hmm, I like this idea. But right now the icons also show the state of 
the file (modified, added, etc.), so if you switch them to a checkbox 
you lose that information. Are you and other people willing to lose that 
information.

Though I've personally never been a huge fan of those icons. They never 
really managed to convey too much meaning to me. So I won't mind 
changing them to something like the single-letter git-status status 
flags. This also gives us a bit of consistency with git-status's flags, 
so people used to the command line will recognize them instantly. 
Thoughts?

Hi again Pratyush Yadav, and other readers!

I hope I don't sound like I am arguing or enthusiastically promoting change
in this subthread. I'm not, my attitude is rather just to explore an idea to see
what others think of it. Some days I have good ideas, other days my ideas
have flaws that I missed, so I like to discuss first.

More important, I want to say that I am very happy to see that there are
folks interested to discuss the Tcl/Tk git GUI tools. In fact I have local Tcl
patches myself, bugfixes and enhancements for git-gui and gitk, which I
would be happy to share except that I do not know how to do that effectively.

I don't enjoy Tcl and because of that I have avoided it and don't consider
my skill level to be very high. I find it rather obtuse, especially the way
it does namespacing, and "upvar" in particular. I struggle to read it without
comments. But I learned enough of Tcl specifically to improve aspects
of git-gui and gitk that were bothering me in the past.

As well as bug fixes, I have enhancements to both that greatly assist
my workflow. For example, in git-gui, I have a hotkey that pastes the
currently highlighted pathname into the commit message. In gitk,
I have added "find all files in commit" to the file list pane, and fixed
the flawed regex matching and associated controls.

My workflow involves a lot of large rebases, and merge conflicts can occur
in the middle of them that affect dozens of files, that need editing
to resolve. That's where easily being able to start an editor from git-gui
in that situation would benefit my workflow. But, it's not a big deal.

Now, to specific comments you made:

> I don't
> think there is any way of finding out the default terminal emulator in
> Linux, and I don't think there is a standard way of making terminal
> emulator launch programs you want.

I agree where you say there is no "standard way", because the
various GUI environments are not consistent (Gnome, LXDE, etc) and
neither are the command line arguments of various terminal emulators,
and sometimes those don't work as expected.

> So your suggestion works only for GUI based editors. We would have to
> mention that only GUI based editors can open files.

Here, I disagree. My suggestion was to provide a double-click facility
that would trigger a command that can be *configured by the user*.

And it is wrong to say that only GUI editors can open files.
For example, my OS is Debian, my GUI is LXDE, and my terminal
emulator is lxterminal. (I don't recommend it, but that's another story).
If I have a terminal window open, I can type the command:
  $ lxterminal -e vi foo
and a new independent terminal window opens with the editor 'vi'
editing the file foo. Similar functionality can be achieved from a
.desktop file, or from a shell script.

Here is a demo Tcl script (working here) that confirms one way
of spawning an editor from Tcl in a terminal window under LXDE:

##### begin script #####
#!/usr/bin/tclsh

package require Tk

# name of this script
set scriptname [info script]

# demo user command
set command "lxterminal -e vi -R $scriptname"

# create text widget
pack [text .t]

# add text to show that we are running
.t insert end "$scriptname: Running: $command\n"

# run the demo command
set chan [open "| $command"]

# (at this point, a new terminal window appears
# containing vi displaying this script file)

# add text to show that we did not block on command
.t insert end "$scriptname: Reached end\n"

##### end script #####

Ah, this is hilarious and embarassing. It confirms what I wrote in my other
message:
  Some days I have good ideas, other days my ideas
  have flaws that I missed, so I like to discuss first.

ie, Some days I'm an idiot! I completely forgot about those other icons!
I like them! In particular, the one that indicates removed files, and
the special one that indicates when a committed file has been replaced
by a symlink, or vice versa, are very valuable to me.

I don't really want any of this to change. I only suggested the change
because I didn't want to appear totally negative. So I tried to come up
with an alternative suggestion. But it was a dumb proposal.

So dumb in fact that I'm now arguing against it :(
Oh well :D
Anyway, I'm a fan of those icons, please don't change them.

I have quite the opposite experience with Tcl. I've been a C person for 
a long time, and was never a big fan of scripting languages. But I have 
been enjoying hacking in Tcl. But I do agree that some parts of Tcl are 
rather strange, and not easy for readability.

I'd be happy to look at your enhancements, and try to fine tune the 
code, but I would point out that some things might just be too specific 
to your workflow, and won't work for the rest of the people using 
git-gui. So do take that into account if you do decide to send some 
improvements in.

FYI, I'm not the maintainer of gitk. So patches for it should be sent to 
Paul Mackerras <paulus@ozlabs.org>.

Ah! I have used this many times (for gnome-terminal), but for some 
reason it didn't occur to me to have a customizable editor command. 
FWIW, I am in favor of something like this being used in git-gui.

If you would volunteer to send patches implementing something like that, 
I would be happy to review. As for me doing it myself, I can't really 
say if or when I can get to it. I have limited time available, and there 
are some other things I'd rather do first.
