62f9a632c8 git-gui: use shell to launch textconv filter in "blame"
The textconv filters may include multiple arguments and may make use
of unix shell features. To maintain compatibility with 'git blame'
ensure these commands are passed through bash.

8c76212529 git-gui: Add a simple implementation of SSH_ASKPASS.
OpenSSH allows specifying an external program to use
for direct user interaction. While most Linux systems
already have such programs, some environments, for
instance, msysgit, lack it. This patch adds a simple
fallback Tcl implementation of the tool.

In msysgit it is also necessary to set a fake value of
the DISPLAY variable, because otherwise ssh won't even
try to use SSH_ASKPASS handlers.

f8f1acf339 git-gui: Correct installation of library to be $prefix/share
We always wanted the library for git-gui to install into the
$prefix/share directory, not $prefix/libexec/share.  All of
the files in our library are platform independent and may
be reused across systems, like any other content stored in
the share directory.

Our computation of where our library should install to was broken
when git itself started installing to $prefix/libexec/git-core,
which was one level down from where we expected it to be.

df4ec4cf6f git-gui: Avoid hardcoded Windows paths in Cygwin package files
When we are being built by the Cygwin package maintainers we need to
embed the POSIX path to our library files and not the Windows path.
Embedding the Windows path means all end-users who install our Cygwin
package would be required to install Cygwin at the same Windows path
as the package maintainer had Cygwin installed to.  This requirement
is simply not user-friendly and may be infeasible for a large number
of our users.

We now try to auto-detect if the Tcl/Tk binary we will use at runtime
is capable of translating POSIX paths into Windows paths the same way
that cygpath does the translations.  If the Tcl/Tk binary gives us the
same results then it understands the Cygwin path translation process
and should be able to read our library files from a POSIX path name.

If it does not give us the same answer as cygpath then the Tcl/Tk
binary might actually be a native Win32 build (one that is not
linked against Cygwin) and thus requires the native Windows path
to our library files.  We can assume this is not a Cygwin package
as the Cygwin maintainers do not currently ship a pure Win32 build
of Tcl/Tk.

651fbba2d3 git-gui: Default TCL_PATH to same location as TCLTK_PATH
Most users set TCLTK_PATH to tell git-gui where to find wish, but they
fail to set TCL_PATH to the same Tcl installation.  We use the non-GUI
tclsh during builds so headless systems are still able to create an
index file and create message files without GNU msgfmt.  So it matters
to us that we find a working TCL_PATH at build time.

If TCL_PATH hasn't been set yet we can take a better guess about what
tclsh executable to use by replacing 'wish' in the executable path with
'tclsh'.  We only do this replacement on the filename part of the path,
just in case the string "wish" appears in the directory paths.  Most of
the time the tclsh will be installed alongside wish so this replacement
is a sensible and safe default.

3470adabad git-gui: Fallback to Tcl based po2msg.sh if msgfmt isn't available
If msgfmt fails with exit code 127 that typically means the program
is not found in the user's PATH and thus cannot be executed by make.
In such a case we can try to fallback to the Tcl based po2msg program
that we distributed with git-gui, as it does a "good enough" job.

We still don't default to po2msg.sh however as it does not perform
a lot of the sanity checks that msgfmt does, and quite a few of

51a41ac4ef git-gui: Use proper Windows shortcuts instead of bat files
On Windows its better to use a shortcut (.lnk file) over a batch
script (.bat) as we can specify the icon file for the .lnk and
thus have these git specific objects appear on the desktop with
that git specific icon file.

Unfortunately the authors of Tcl did not bless us with the APIs
needed to create shortcuts from within Tcl.  But Microsoft did
give us Windows Scripting Host which allows us to execute some
JavaScript that calls some sort of COM object that can operate
on a .lnk file.

We now build both Cygwin and non-Cygwin "desktop icons" as proper
Windows .lnk files, using the "Start in" property of these files
to indicate the working directory of the repository the user wants
to launch.

72a8e81d45 git-gui: Support a native Mac OS X application bundle

our own info list and icon set.

Although the Makefile change here is rather large it makes for a
much more pleasant user experience on Mac OS X as git-gui now has
its own icon on the dock, in the standard tk_messageBox dialogs,
and the application name now says "Git Gui" instead of "Wish" in
locations such as the menu bar and the alt-tab window.

2f7c9a7f31 git-gui: Support native Win32 Tcl/Tk under Cygwin
Cygwin has been stuck on the 8.4.1 version of Tcl/Tk for quite some
time, even though the main Tcl/Tk distribution is already shipping
an 8.4.15.  The problem is Tcl/Tk no longer supports Cygwin so
apparently building the package for Cygwin is now a non-trivial task.

Its actually quite easy to build the native Win32 version of Tcl/Tk
by compiling with the -mno-cygwin flag passed to GCC but this means
we lose all of the "fancy" Cygwin path translations that the Tcl
library was doing for us.  This is particularly an issue when we
are trying to start git-gui through the git wrapper as the git
wrapper is passing off a Cygwin path for $0 and Tcl cannot find
the startup script or the library directory.

We now use `cygpath -m -a` to convert the UNIX style paths to Windows
style paths in our startup script if we are building on Cygwin.
Doing so allows either the Cygwin-ized Tcl/Tk 8.4.1 that comes with
Cygwin or a manually built 8.4.15 that is running the pure Win32
implementation to read our script.

042f53c569 git-gui: Provide 'uninstall' Makefile target to undo an installation

if git-gui goes to the wrong place during the initial install,
or if they are unhappy with the tool and want to remove it from

We currently assume that the complete set of files we need to delete
are those defined by our Makefile and current source directory.
This could differ from what the user actually has installed if they
installed one version then attempt to use another to perform the
uninstall.  Right now I'm just going to say that is "pilot error".
Users should uninstall git-gui using the same version of source
that they used to make the installation.  Perhaps in the future we
could read tclIndex and base our uninstall decisions on its contents.

libdir meaning here in git-gui's Makefile breaks idomatic expressions
like rpm specifile "make libdir=%_libdir".

Originally I asked that the git.git Makefile undefine libdir before
it calls git-gui's own Makefile but it turns out this is very hard
to do, if not impossible.  Renaming our libdir to gg_libdir resolves
this case with a minimum amount of fuss on our part.

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.

Alex Riesen wanted a quieter installation process for git and its
contained git-gui.  His earlier patch to do this failed to work
properly when V=1, and didn't really give a great indication of

These rules are a little bit on the messy side, as each of our
install actions is composed of at least two variables, but in the
V=1 case the text is identical to what we had before, while in the
non-V=1 case we use some more complex rules to show the interesting
details, and hide the less interesting bits.

We now can also set QUIET= (nothing) to see the rules that are used
when V= (nothing), so we can debug those too if we have to.  This is
actually a side-effect of how we insert the @ into the rules we use
for the "lists of things", like our builtins or our library files.

82a2d6bdf9 git-gui: Correctly install to /usr/bin on Cygwin
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:

  /usr/bin   = c:\cygwin\bin
  /usr/share = c:\cygwin\usr\share

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.

ea75ee3598 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.

b9e7efb8b5 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.

1f07c4e5ce git-gui: Define a simple class/method system
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.

A simple class might be defined as:

  class map {
    field data
    field size 0

    constructor {} {
      return $this
    }
    method set {name value} {
      set data($name) $value
      incr size
    }
    method size {} {
      return $size
    } ifdeleted { return 0 }
  }

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.

f522c9b5ed 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
huge migration of code from one file to many smaller files.  All of
the new changes are to setup the library path and install the library
files.

c6a5e40303 git-gui: Track our own embedded values and rebuild when they change
Like core-Git we now track the values that we embed into our shell
script wrapper, and we "recompile" that wrapper if they are changed.
This concept was lifted from git.git's Makefile, where a similar
thing was done by Eygene Ryabinkin.  Too bad it wasn't just done
here in git-gui from the beginning, as the git.git Makefile support
for GIT-GUI-VARS was really just because git-gui doesn't do it on
its own.

Junio rightly pointed out this patch doesn't handle the
`make install` target very well:
