git-gui: Include a Push action on the left toolbar
Pushing changes to a remote system is a very common action for
many users of git-gui, so much so that in some workflows a user
is supposed to push immediately after they make a local commit
so that their change(s) are immediately available for their
teammates to view and build on top of.
Including the push button right below the commit button on the
left toolbar indicates that users should probably perform this
action after they have performed the commit action.

Users often need to be able to push the current branch so that they
can publish their recent changes to anyone they are collaborating
with on the project. Associating a keyboard action with this will
make it easier for keyboard-oriented users to quickly activate the
push features.

git-gui: Unlock the index when cancelling merge dialog
Pressing the escape key while in the merge dialog cancels the merge

the Cancel button, using it closes the dialog but does not release
the index lock, rendering git-gui frozen until you restart it. We
now properly release the index lock when the Cancel button is used.

git-gui: properly popup error if gitk should be started but is not installed
On 'Visualize ...', a gitk process is started. Since it is run in the
background, catching a possible startup error doesn't work, and the error
output goes to the console git-gui is started from. The most probable
startup error is that gitk is not installed; so before trying to start,
check for the existence of the gitk program, and popup an error message
unless it's found.

git-gui: Don't require a .pvcsrc to create Tools/Migrate menu hack
The Tools/Migrate menu option is a hack just for me. Yes, that's
right, git-gui has a hidden feature that really only works for me,
and the users that I support within my day-job's great firewall.
The menu option is not supported outside of that environment.
In the past we only enabled Tools/Migrate if our special local
script 'gui-miga' existed in the proper location, and if there
was a special '.pvcsrc' in the top level of the working directory.
This latter test for the '.pvcsrc' file is now failing, as the file
was removed from all Git repositories due to changes made to other
tooling within the great firewall's realm.
I have changed the test to only work on Cygwin, and only if the
special 'gui-miga' is present. This works around the configuration
changes made recently within the great firewall's realm, but really
this entire Tools/Migrate thing should be abstracted out into some
sort of plugin system so other users can extend git-gui as they need.

git-gui: Don't require $DISPLAY just to get --version
Junio asked that we don't force the user to have a valid X11 server
configured in $DISPLAY just to obtain the output of `git gui version`.
This makes sense, the user may be an automated tool that is running
without an X server available to it, such as a build script or other
sort of package management system. Or it might just be a user working
in a non-GUI environment and wondering "what version of git-gui do I
have installed?".
Tcl has a lot of warts, but one of its better ones is that a comment
can be continued to the next line by escaping the LF that would have
ended the comment using a backslash-LF sequence. In the past we have
used this trick to escape away the 'exec wish' that is actually a Bourne
shell script and keep Tcl from executing it.
I'm using that feature here to comment out the Bourne shell script and
hide it from the Tcl engine. Except now our Bourne shell script is a
few lines long and checks to see if it should print the version, or not.

git-gui: Bind Tab/Shift-Tab to cycle between panes in blame
The blame viewer is composed of two different areas, the file

Shift-Tab to jump from the one half to the other in a cycle.

Mark Levedahl <mlevedahl@gmail.com> noted that installation on Cygwin
to /usr/bin can cause problems with the automatic guessing of our
library location. The problem is that installation to /usr/bin
means we actually have:
So git-gui guesses that its library should be found within the
c:\cygwin\share directory, as that is where it should be relative
to the script itself in c:\cygwin\bin.
In my first version of this patch I tried to use `cygpath` to resolve
/usr/bin and /usr/share to test that they were in the same relative
locations, but that didn't work out correctly as we were actually
testing /usr/share against itself, so it always was equal, and we
always used relative paths. So my original solution was quite wrong.
Mark suggested we just always disable relative behavior on Cygwin,
because of the complexity of the mount mapping problem, so that's
all I'm doing.

git-gui: Save geometry before the window layout is damaged
Because Tk does not assure us the order that it will process
children in before it destroys the main toplevel we cannot safely
save our geometry data during a "bind . <Destroy>" event binding.
The geometry may have already changed as a result of a one or
more children being removed from the layout. This was pointed
out in gitk by Mark Levedahl, and patched over there by commit b6047c5a8166a71e01c6b63ebbb67c6894d95114.

git-gui: Give amend precedence to HEAD over MERGE_MSG
Apparently git-commit.sh (the command line commit user interface in
core Git) always gives precedence to the prior commit's message if
`commit --amend` is used and a $GIT_DIR/MERGE_MSG file also exists.
We actually were doing the same here in git-gui, but the amended
message got lost if $GIT_DIR/MERGE_MSG already existed because
we started a rescan immediately after loading the prior commit's
body into the edit buffer. When that happened the rescan found
MERGE_MSG existed and replaced the commit message buffer with the
contents of that file. This meant the user never saw us pick up
the commit message of the prior commit we are about to replace.
Johannes Sixt <J.Sixt@eudaptics.com> found this bug in git-gui by
running `git cherry-pick -n $someid` and then trying to amend the
prior commit in git-gui, thus combining the contents of $someid
with the contents of HEAD, and reusing the commit message of HEAD,
not $someid. With the recent changes to make cherry-pick use the
$GIT_DIR/MERGE_MSG file Johannes saw git-gui pick up the message
of $someid, not HEAD. Now we always use HEAD if we are amending.

git-gui: Favor the original annotations over the recent ones
Usually when you are looking at blame annotations for a region of
a file you are more interested in why something was originally
done then why it is here now. This is because most of the time
when we get original annotation data we are looking at a simple
refactoring performed to better organize code, not to change its
semantic meaning or function. Reorganizations are sometimes of
interest, but not usually.
We now show the original commit data first in the tooltip. This
actually looks quite nice as the original commit will usually have an
author date prior to the current (aka move/copy) annotation's commit,
so the two commits will now tend to appear in chronological order.
I also found myself to always be clicking on the line of interest
in the file column but I always wanted the original tracking data
and not the move/copy data. So I changed our default commit from
$asim_data (the simple move/copy annotation) to the more complex
$amov_data (the -M -C -C original annotation).

git-gui: Improve our labeling of blame annotation types

current file (no -M -C -C) as that set of annotations tells us who
put the hunk here (who moved/copied it). I'm now calling the -M
-C -C pass "original location annotations" as that's what we're
really digging for.
I also tried to clarify some of the text in the hover tooltip.

git-gui: Use three colors for the blame viewer background
To prevent neighboring lines that are different commits from using
the same background color we now use 3 colors and assign them
by selecting the color that is not used before or after the line
in question. We still color "on the fly" as we receive hunks from
git-blame, but we delay our color decisions until we are getting
the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.
Credit goes to Martin Waitz for the tri-coloring concept.

When the user clicks on a commit link within one of the columns
in the blame viewer we now jump them not just to that commit/file
pair but also to the line of the original file. This saves the
user a lot of time, as they don't need to search through the new
file data for the chunk they were previously looking at.
We also restore the prior view when the user clicks the back button
to return to a pior commit/file pair that they were looking at.
Turned out this was quite tricky to get working in Tk. Every time
I tried to jump the text widgets to the correct locations by way
of the "yview moveto" or "see" subcommands Tk performed the change
until the current event finished dispatching, and then reset the
views back to 0, making the change never take place. Forcing Tk
to run the pending events before we jump the UI resolves the issue.

git-gui: Run blame twice on the same file and display both outputs
We now perform two passes over any input file given to the blame
viewer. Our first pass is a quick "git-blame" with no options,
getting the details of how each line arrived into this file. We
are specifically ignoring/omitting the rename detection logic as
this first pass is to determine why things got into the state they
are in.
Once the first pass is complete and is displayed in the UI we run
a second pass, using the much more CPU intensive "-M -C -C" options
to perform extensive rename/movement detection. The output of this
second pass is shown in a different column, allowing the user to see
for any given line how it got to be, and if it came from somewhere
else, where that is.
This is actually very instructive when run on our own lib/branch.tcl
script. That file grew recently out of a very large block of code
in git-gui.sh. The first pass shows when I created that file, while
the second pass shows the original commit information.

git-gui: Rename fields in blame viewer to better descriptions
Calling the commit message pane $w_cmit is a tad confusing when

So w_cmit -> w_cviewer, as it is the "commit viewer"; and
w_cgrp -> w_amov as it is the "annotated commit + move tracking"
column. Also changed line_data -> amov_data, as that list is
exactly the results shown in w_amov.
Why call the column "move tracking"? Because this column holds
data from "git blame -M -C". I'm considering adding an additional
column that holds the data from "git blame" without -M/-C, showing
who did the copy/move, and when they did it.

git-gui: Switch internal blame structure to Tcl lists
The Tcl list datatype is significantly faster to work with than
the array type, especially if our indexes are a consecutive set
of numbers, like say line numbers in a file.
This rather large change reorganizes the internal data structure
of the blame viewer to use a proper Tcl list for the annotation
information about a line. Each line is given its own list within
the larger line_data list, where the indexes correspond to various
facts about that particular line.
The interface does seem to be more responsive this way, with less
time required by Tcl to process blame, and to switch to another
version of the same file. It could just be a placebo effect, but
either way most Tcl experts perfer lists for this type of work over
arrays.

The array variable "order" used to be used to tell us in what
order each commit was received in. Recent changes have removed
that need for an ordering and the "order" array is now just a

Most source code files are under 9,999 lines of text, so using a

Unfortunately when I added the right margin earlier (when I removed

margin. This put the line numbers too close to the commit column in
any file with more than 999 lines in it.

git-gui: Remove unnecessary space between columns in blame viewer
On Mac OS X the OS has "features" that like to draw thick black
borders around the text field that has focus. This is nice if
you want to know where your text is going and are blind as a bat,
but it isn't the best thing to have in a table that is being
faked through the abuse of Tk text widgets.
By setting our takefocus, highlightthickness and padx/y we can

background color smoothly run across the entire line of commit data,

git-gui: Remove the loaded column from the blame viewer
Originally I had placed this loaded column between the line number
and the file line data to help users know if a particular line has
received annotation data or not yet. This way users would know if
the line(s) they were interested in were ready for viewing, or if
they still had to wait. It also was an entertaining way for the
user to spend their time waiting for git-blame --incremental to
compute the complete set of annotations.
However it is completely useless now that we show the abbreviated
commit SHA-1 and author initials in the leftmost column. That area
is empty until we get the annotation data, and as soon as we get it
in we display something there, indicating to the user that there is
now blame data ready. Further with the tooltips the user is likely
to see the data as soon as it comes in, as they are probably not
keeping their mouse perfectly still. So I'm removing the field to
save screen space for more useful things, like file content.

git-gui: Allow digging through history in blame viewer
gitweb has long had a feature where the user can click on any
commit the blame display and go visit that commit's information
page. From the user could go get the blame display for the file
they are tracking, and try to digg through the history of any
part of the code they are interested in seeing.
We now offer somewhat similiar functionality in git-gui. The 4
digit commit abreviation in the first column of our blame view is
now offered as a hyperlink if the commit isn't the one we are now
viewing the blame output for (as there is no point in linking back
to yourself). Clicking on that link will stop the current blame
engine (if still running), push the new target commit onto the
history stack, and restart the blame viewer at that commit, using
the "original file name" as supplied by git-blame for that chunk
of the output.
Users can navigate back to a version they had been viewing before
by way of a back button, which offers the prior commits in a popup
menu displayed right below the back button. I'm always showing the
menu here as the cost of switching between views is very high; you
don't want to jump to a commit you are not interested in looking at
again.
During switches we throw away all data except the cached commit data,
as that is relatively small compared to most source files and their
annotation marks. Unfortunately throwing this per-file data away in
Tcl seems to take some time; I probably should move the line indexed
arrays to proper lists and use [lindex] rather than the array lookup
(usually lists are faster).
We now start the git-blame process using "nice", so that its priority
will drop hopefully below our own. If I don't do this the blame engine
gets a lot of CPU under Windows 2000 and the git-gui user interface is
almost non-responsive, even though Tcl is just sitting there waiting
for events.

git-gui: Display a progress bar during blame annotation gathering
Computing the blame records for a large file with a long project
history can take git a while to run; traditionally we have shown
a little meter in the status area of our blame viewer that lets
the user know how many lines have been finished, and how far we
are through the process.
Usually such progress indicators are drawn with a little progress
bar in the window, where the bar shows how much has been completed
and hides itself when the process is complete. I'm using a very
simple hack to do that: draw a canvas with a filled rectangle.
Of course the time remaining has absolutely no relationship to the
progress meter. It could take very little time for git-blame to get
the first 90% of the file, and then it could take many times that to
get the remaining 10%. So the progress meter doesn't really have any
sort of assurances that it relates to the true progress of the work.
But in practice on some ugly history it does seem to hold a reasonable
indicator to the completion status. Besides, its amusing to watch and
that keeps the user from realizing git is being somewhat slow.

git-gui: Allow the user to control the blame/commit split point
At one point I tried to present the blame viewer to an audience of
people on a 640 by 480 pixel LCD projector. This did not work at
all as the top area (the file data) was taking up all of the screen
realestate and the split point was not adjustable by the user. In
general locking the user into a specific ratio of display is just
not user friendly.
So we now place a split pane control into the middle of our blame
window, so the user can adjust it to their current needs. If the
window increases (or decreases) in height we assign the difference
to the file data area, as that is generally the area of the window
that users are trying to see more of when they grow the window.
Unfortunately there appears to be a bug in the "pack" layout manager
in Tcl/Tk 8.4.1. The status bar and the lower commit pane was being
squashed if the window decreased in height. I think the pack manager
was just not decreasing the size of the panedwindow slave properly if
the main window shrank. Switching to the "grid" layout manager fixes
the problem, but is slightly uglier setup code.

Frequently when I'm looking at blocks of code in the blame
viewer I want to know who is the culprit, or who I should
be praising for a job well done. The tooltips nicely show
this if I mouse over a block, but it doesn't work to get
this detail at a glance.
Since we don't use the leftmost commit column for anything
after the first line within a commit group I'm now tossing
the author's initials into that field, right justified. It
is quite clearly not a SHA-1 number as we always show the
SHA-1 in lowercase, while we explicitly select only the
uppercase characters from an author's name field, and only
those that are following whitespace.
I'm using initials here over anything else as they are quite
commonly unique within small development teams. The leading
part of the email address field was out for some of the teams
I work with, as there the email addresses are all of the form
"Givenname.Surname@initech.com". That will never fit into the

The git-gui blame viewer has always been ugly as s**t. Linus Torvalds
suggested the coloring scheme I'm using here, which is two different
shades of grey for the background colors, and black text on a pale green
background for the currently selected/focused commit.
The difference is a massive improvement. The interface no longer will
cause seizures in people who are prone to that sort of thing. It no
longer uses a very offensive hot pink. The green being current actually
makes sense. And not having the background of the other non-current
lines change when you change the current commit is really a big deal.

git-gui: Guess our share/git-gui/lib path at runtime if possible
Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script. Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.
Most of this is a hack. We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

git-gui: Gracefully handle bad TCL_PATH at compile time
Petr Baudis pointed out the main git.git repository's Makefile dies
now if git-gui 0.7.0-rc1 or later is being used and TCL_PATH was not
set to a working tclsh program path. This breaks people who may have
a working build configuration today and suddenly upgrade to the latest
git release.
The tclIndex is required for git-gui to load its associated lib files,
but using the Tcl auto_load procedure to source only the files we need
is a performance optimization. We can emulate the auto_load by just
source'ing every file in that directory, assuming we source class.tcl
first to initialize our crude class system.

We can use [list ...] rather than "", especially when we are talking
about values as then they are properly escaped if necessary. Small
nit, but probably not a huge deal as the only data being inlined here
is Tk paths.
Some of the lines in the parser code were longer than 80 characters
wide, and they actually were all the same value on the end part of
the line. Rather than keeping the mess copied-and-pasted around we
can set the last argument into a local variable and reuse it many
times.
The commit display code was also rather difficult to read on an 80
character wide terminal, so I'm moving it all into a double quoted
string that is easier to read.

git-gui: Smarter command line parsing for browser, blame
The browser subcommand now optionally accepts a single revision
argument; if no revision argument is supplied then we use the

its a nice option.
Our blame subcommand now tries to perform the same assumptions
as the command line git-blame; both the revision and the file
are optional. We assume the argument is a filename if the file
exists in the working directory, otherwise we assume the argument
is a revision name. A -- can be supplied between the two to force
parsing, or before the filename to force it to be a filename.

git-gui: Convert blame to the "class" way of doing things
Our blame viewer code has historically been a mess simply
because the data for multiple viewers was all crammed into

git-gui: Don't attempt to inline array reads in methods
If a variable reference to a field is to an array, and it is

it an inlined [set foo] call as the regexp was converting the

git-gui: Convert browser, console to "class" format
Now that we have a slightly easier method of working with per-widget
data we should make use of that technique in our browser and console
meta-widgets, as both have a decent amount of information that they
store on a per-widget basis and our current approach of handling
it is difficult to follow.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
As most of the git-gui interface is based upon "meta-widgets"
that need to carry around a good deal of state (e.g. console
windows, browser windows, blame viewer) we have a good deal
of messy code that tries to store this meta-widget state in
global arrays, where keys into the array are formed from a
union of a unique "object instance id" and the field name.
This is a simple class system for Tcl that allows us to
hide much of that mess by making Tcl do what it does best;
process strings to manipulate its own code during startup.
Each object instance is placed into its own namespace. The
namespace is created when the object instance is created and
the namespace is destroyed when the object instance is removed
from the system. Within that namespace we place variables for
each field within the class; these variables can themselves be
scalar values or full-blown Tcl arrays.
All fields must be declared before any constructors or methods. This
allows our class to generate a list of the fields so it can properly
alter the definition of the constructor and method bodies prior to
passing them off to Tcl for definition with proc. A field may optionally
be given a default/initial value. This can only be done for non-array
type fields.
Constructors are given full access to all fields of the class, so they
can initialize the data values. The default values of fields (if any)
are set before the constructor runs, and the implicit local variable
$this is initialized to the instance identifier.
Methods are given access to fields they actually use in their body.
Every method has an implicit "this" argument inserted as its first
parameter; callers of methods must be sure they supply this value.
Some basic optimization tricks are performed (but not much). We
try to only upvar (locally bind) fields that are accessed within a
method, but we err on the side of caution and may upvar more than
we need to. If a variable is accessed only once within a method
and that access is by $foo (read) we avoid the upvar and instead
use [set foo] to obtain the value. This is slightly faster as Tcl
does not need to lookup the variable twice.
We also offer some small syntatic sugar for interacting with Tk and
the fileevent callback system in Tcl. If a field (say "foo") is used
as "@foo" we insert instead the true global variable name of that
variable into the body of the constructor or method. This allows easy
binding to Tk textvariable options, e.g.:
label $w.title -textvariable @title
Proper namespace callbacks can also be setup with the special cb proc
that is defined in each namespace. [cb _foo a] will invoke the method
_foo in the current namespace, passing it $this as the first (implied)
parameter and a as the second parameter. This makes it very simple to
connect an object instance to a -command option for a Tk widget or to
a fileevent readable or writable for a file channel.

git-gui: Include commit id/subject in merge choices
When merging branches using our local merge feature it can be
handy to know the first few digits of the commit the ref points
at as well as the short description of the branch name.
Unfortunately I'm unable to use three listboxes in a row, as Tcl
freaks out and refuses to let me have a selection in more than
one of them at any given point in time. So instead we use a
fixed width font in the existing listbox and organize the data
into three columns. Not nearly as nice looking, but users can
continue to use the listbox's features.

Johannes Sixt pointed out that git-gui was randomly selecting
which branch (or tag!) it will show in the merge dialog when
more than one ref points at the same commit. This can be a
problem for the user if they want to merge a branch, but the
ref that git-gui selected to display was actually a tag that
points at the commit at the tip of that branch. Since the
user is looking for the branch, and not the tag, its confusing
to not find it, and worse, merging the tag causes git-merge to
generate a different message than if the branch was selected.
While I am in here and am messing around I have changed the
for-each-ref usage to take advantage of its --tcl formatting,
and to fetch the subject line of the commit (or tag) we are
looking at. This way we could present the subject line in the
UI to the user, given them an even better chance to select
the correct branch.

git-gui: Refactor into multiple files to save my sanity
I'm finding it difficult to work with a 6,000+ line Tcl script
and not go insane while looking for a particular block of code.
Since most of the program is organized into different units of
functionality and not all users will need all units immediately
on startup we can improve things by splitting procs out into
multiple files and let auto_load handle things for us.
This should help not only to better organize the source, but
it may also improve startup times for some users as the Tcl
parser does not need to read as much script before it can show
the UI. In many cases the user can avoid reading at least half
of git-gui now.
Unfortunately we now need a library directory in our runtime
location. This is currently assumed to be $(sharedir)/git-gui/lib
and its expected that the Makefile invoker will setup some sort of
reasonable sharedir value for us, or let us assume its going to be
$(gitexecdir)/../share.
We now also require a tclsh (in TCL_PATH) to just run the Makefile,
as we use tclsh to generate the tclIndex for our lib directory. I'm
hoping this is not an unncessary burden on end-users who are building
from source.
I haven't really made any functionality changes here, this is just a

work themselves using "encoding convertfrom" and "convertto", as
that was the only way I could make UTF-8 filenames work properly.
