Command-line git Vs IDE+plugin?

Command-line git Vs IDE+plugin?

[Matthieu Moy]

Hi,

I'm normally an Emacs+command-line user, but I also use Eclipse or
Netbeans on some projects. I tried using EGit and the Netbeans plugin
for Git, but found the GUI both more comlex and less powerful than the
command-line. I end-up using command-line git in a terminal, outside the
IDE (and do a refresh in the IDE after commands that modify the
worktree). Obviously, being a long-time command-line user, I'm rather
heavily biaised ;-).

I was wondering whether others had similar (or not) experience. In
particular, as a teacher, I'm wondering whether I should push my
students towards the GUI in the IDE, or advise them to keep using the
command-line (we teach them git with the command-line first anyway, but
after a year of practice, we may want to show them the GUI equivalent).

Thanks,

Did you give magit a try? It's really an awesome emacs plugin, which
gives me pretty much the same control as the command line experience
without the pain. Ask me more about if if you're interested.

In my experience, most people prefer the GUI version, simply because
to them it's more intuitive and stuffs like visual diffs tools are
integrated, which makes them quickly realise the benefits. That said,
because it's "easier" they tend to not dig deeper and are lost at the
first little problem, e.g a simple conflict becomes difficult to
solve.

In my opinion to *learn* git it's useful to learn with the console
first, just like when you learn C++ it's useful to start with simple
exercises and not jump straight to GUI programming. When they become
familiar with the basics, I think it's nice to show them about  `git
log --graph --all --decorate` and the gitk/gitg equivalent, or "git
diff" and the vimdiff/ediff/visual merge/kdiff equivalent.

When they understand git reasonably (or if they are not lazy people
and willing to learn), then show them full integrations like
TortoiseGit (or probably the Netbeans plugin), which are nice when
everything works but you have to know console git to fix things or
simply to be aware of their limitations.

TL;DR, I think both are necessary, the command line to understand git
and the integrations/wrappers to add sugar to your daily workflow.
Visual tools are great, especially visual diffs for merging.

I've used the Git backend for DVC in the past. I gave Magit a try very
long ago, and found DVC superior at that time (I was the main author, so
I was once again heavily biaised). But I got used to the command-line
more and more (within an ansi-term window inside Emacs most of the
time), and ended up abandonning DVC (both as a user and contributor).

Maybe I'll give it another try.

When it comes to Git on Windows with a GUI front-end, I would recommend
to take a look at Git Extensions [1] as well.

Similar. When I used eclipse I didn't even try to use the plugins
and just stayed on the command line. (Well, almost, but back then
jgit couldn't deal with submodules which I needed.)

I have the same experience with the few git GUIs I tried - none
stuck to me. Even 'git gut' hardly made the cut, I stay with
the command line except for gitk which is very useful to see
what you've done.

For people that live in the IDE anyway the mileage will vary,
but for me there is always some extra mismatch to overcode -
I know what the CLI is doing and think in terms of these
operations, and I'd need to understand what the GUI is thinkig
to be good for me (i.e. how operations are implemented there);
for me it always fells like a mist over the repo.

And I know that I'm missing on some features - the integration of history
examination into codebrowsing schoould be a good thing.

Still, if you show them eclipse, I'd also show them the git integration
in there. I dread the moment I have to show someone how to merge a pull
(or any merge) in eclipse though. :-(

I'm a software engineer now with an education as a high school teacher. From a 
theoretical point of view it's preferable to avoid any abstraction done by a 
GUI and use commandline Git. Only gitk is useful to have a visual _feedback_ 
of the actions done on the commandline.

But also from experience I can tell that without exception everybody whom I 
teached Git understood it only after being introduced to the basic concepts of 
Git and how to inspect and operate them on the commandline. Others told me 
from similar experiences.

Those concepts are:

- hashes
- content adressable storage
- blops being referenced by trees being referenced by commits

My collegues meanwhile dumped their graphical Git tool because they learned 
that they have better control over Git when using it from the commandline.

Interesting.  I think any UI needs to fill three objectives:

 - make common tasks easy;
 - make complex tasks possible; and
 - help users build the right mental model.

As a tool from Linus school, we started from the second and the
third point.  Our UI (i.e. CLI) has long been notorious for lacking
in the first department, and we have worked long and hard to improve
on that front.  While there are more work needed for CLI, your
observation, and a similar experience by Noufal in the thread, hints
me that the available GUI tools have concentrated primarily on the
first point but are still lacking in the rest.

Perhaps I am being naïve, but I would expect that a GUI is a much
better vehicle to help users build the right mental model.  Unlike
CLI, it has a canvas to draw pretty pictures and present the users
what the user is really doing after all.

And I am sure GUI people will eventually realize that potential in
the tools they are building, and the world will become a better place
for both GUI and CLI users ;-).  I found "ungit" an interesting
experiment that goes into that direction.

Being forever hopeful...

One thing the command-line does well is to give names to concepts
(basically, command names, option names, ...). It's easy to write in a
tutorial or an email "run the command 'git foo'". It's less easy to
write "click on that red button, on the right of the green one".
Then, it's clear to everyone what "commit", "rebase", "amend" & so mean,
regardless of the colors of buttons (that's one of the reasons I use the
english words even when I speak french).

That said, even when I teach the command-line, gitk is a very valuable
tool to explain what the DAG is and how branching works.

And it is also easier for many to press a button than writing a
command. This is a bad thing, in my experience. In a GUI, people tend
to take chances: "Oh, reset, that sounds like what I want. What, it
did not work? Oh there is this option 'hard', let's tick it and see
what happens."

Another thing GUIs do not (often) offer is history. I would be lost if
I couldn't see what I was trying to do 5 commands ago (before someone
interrupted me), or refer to a previous error message.

But if you cannot touch-type, buttons are going to be more attractive.

A great reference I always point people to for exactly those reasons is

I teach git professionally and I do so using only the command line
interface. This allows me to explain the underlying structures and how
data is organised so that commands don't look like magic spells that
solve problems. It helps people build a mental model of how the software
works so that they can solve most problems themselves or atleast ask the
right questions. I actively discourage people from using IDE plugins and
graphical front ends for the training because they hide the details
which I think are important.

I use gitk and some home brew scripts to show how the DAG and objects
get created and their structures but that is purely for illustrative
purposes.

I also mention a few git front ends in passing like magit (which I use)
and tortoise (since many of the trainings I conduct are for Windows
users) at the end of the course so that people are aware of
alternatives.

My $0.02 as someone who performs some part-time SCM admin tasks for a
moderately sized group of engineers (~40) with varying degrees of
experience.

Some people are scared by a command line and think poking buttons in an
IDE is preferable (and somehow safer). As others have pointed out the
first sign of trouble they shuffle over to my desk. I see the people
that are comfortable with the command line far less frequently.

I think learning the command line first does help with peoples overall
understanding. Once they have some working knowledge of the basics
introducing some of the tools that integrate with those building blocks
is much easier.

In some respects the gui/IDE is better for some tasks. For example I
don't even bother telling people about 'git add -p' because 'git gui'
provides the same functionality with an interface that is better suited
to picking chunks/lines of code to stage. Another example is Eclipse's
"annotations" which provides the same information as 'git blame' but it
is right there with the code I'm editing.

Specifically about Eclipse; I've personally found that in the days of
Ganymede/Helios the VCS integration built around SVN and the mapping of
SVN concepts to Git was imperfect (impossible?). With Juno/Indigo the
support for DVCSes in general and for Git specifically is greatly
improved but I still rarely use Eclipse to actually make commits.
