If we feed a bad dictionary name to aspell on startup it may appear
to start (as Tcl found the executable in our $PATH) but it fails to
give us the version string. In such a case the close of the pipe
will report the exit status of the process (failure) and that is
an error in Tcl.
We now trap the subprocess failure and display the stderr message
from it, letting the user know why the failure is happening. We then
disable the spell checker, but keep our object instance so the user
can alter their preferred dictionary through the options dialog, and
possibly restart the spell checker.
I was also originally wrong to use "error" here for the display
of the problem to the user. I meant to use "error_popup", which
will open a message box and show the failure in a GUI context,
rather than killing git-gui and showing the message on the console.
Noticed by Ilari on #git.

If we reconnect to the spellchecker there is no reason to resetup
the binding for button 3 on our text widget to show the suggestion

Plus, by moving it out of _connect and into init we can now break
out of _connect earlier if there is something wrong with the pipe,
for example if the dictionary we were asked to load is not valid.

Users may or may not be using aspell here. About the only thing
we are using that is aspell specific (and not supported by ispell
or an ispell variant) is some command line options when we start
up aspell, and a forced encoding of UTF-8. Both of these can be
corrected and/or cleaned up by users through an aspell wrapper
script, or through further improvements to git-gui. There is no
reason to require our translated strings to reference a specific
spell checker, especially if that spell checker implementation is
not very suitable for the language being translated.

If we somehow managed to get our spellchecker instance created but

Many user friendly tools like word processors, email editors and web
browsers allow users to spell check the message they are writing
as they type it, making it easy to identify a common misspelling
of a word and correct it on the fly.
We now open a bi-directional pipe to Aspell and feed the message
text the user is editing off to the program about once every 300
milliseconds. This is frequent enough that the user sees the results
almost immediately, but is not so frequent as to cause significant
additional load on the system. If the user has modified the message
text during the last 300 milliseconds we delay until the next period,
ensuring that we avoid flooding the Aspell process with a lot of
text while the user is actively typing their message.
We wait to send the current message buffer to Aspell until the user
is at a word boundary, thus ensuring that we are not likely to ask
for misspelled word detection on a word that the user is actively
typing, as most words are misspelled when only partially typed,
even if the user has thus far typed it correctly.
Misspelled words are highlighted in red and are given an underline,
causing the word to stand out from the others in the buffer. This is
a very common user interface idiom for displaying misspelled words,
but differs from one platform to the next in slight variations.
For example the Mac OS X system prefers using a dashed red underline,
leaving the word in the original text color. Unfortunately the
control that Tk gives us over text display is not powerful enough
to handle such formatting so we have to work with the least common
denominator.
The top suggestions for a misspelling are saved in an array and
offered to the user when they right-click (or on the Mac ctrl-click)
a misspelled word. Selecting an entry from this menu will replace
the misspelling with the correction shown. Replacement is integrated
with the undo/redo stack so undoing a replacement will restore the
misspelled original text.
If Aspell could not be started during git-gui launch we silently eat
the error and run without spell checking support. This way users
who do not have Aspell in their $PATH can continue to use git-gui,
although they will not get the advanced spelling functionality.
If Aspell started successfully the version line and language are
shown in git-gui's about box, below the Tcl/Tk versions. This way
the user can verify the Aspell function has been activated.
If Aspell crashes while we are running we inform the user with an
error dialog and then disable Aspell entirely for the rest of this
git-gui session. This prevents us from fork-bombing the system
with Aspell instances that always crash when presented with the
current message text, should there be a bug in either Aspell or in
git-gui's output to it.
We escape all input lines with ^, as recommended by the Aspell manual
page, as this allows Aspell to properly ignore any input line that is
otherwise looking like a command (e.g. ! to enable terse output). By
using this escape however we need to correct all word offsets by -1 as
Aspell is apparently considering the ^ escape to be part of the line's
character count, but our Tk text widget obviously does not.
Available dictionaries are offered in the Options dialog, allowing
the user to select the language they want to spellcheck commit
messages with for the current repository, as well as the global
user setting that all repositories inherit.
Special thanks to Adam Flott for suggesting connecting git-gui
to Aspell for the purpose of spell checking the commit message,
and to Wincent Colaiuta for the idea to wait for a word boundary
before passing the message over for checking.

If the horizontal scrollbar isn't currently visible (because it has
not been needed) but we get an update to the scroll port we may find

removing the Tcl procedure name but still leaving the widget name in

The code we use to test if a hook is executable or not differs on
Cygwin from the normal POSIX case. Rather then repeating that for
all three hooks we call in our commit code path we can place the
common logic into a global procedure and invoke it when necessary.
This also lets us get rid of the ugly "|& cat" we were using before
as we can now rely on the Tcl 8.4 feature of "2>@1" or fallback to
the "|& cat" when necessary.
The post-commit hook is now run through the same API, but its outcome
does not influence the commit status. As a result we now show any of
the errors from the post-commit hook in a dialog window, instead of on
the user's tty that was used to launch git-gui. This resolves a long
standing bug related to not getting errors out of the post-commit hook
when launched under git-gui.

Under core Git the git-commit tool will invoke the commit-msg hook
if it exists and is executable to the user running git-commit. As
a hook it has some limited value as it cannot alter the commit, but
it can modify the message the user is attempting to commit. It is
also able to examine the message to ensure it conforms to some local
standards/conventions.
Since the hook takes the name of a temporary file holding the message
as its only parameter we need to move the code that creates the temp
file up earlier in our commit code path, and then pass through that
file name to the latest stage (where we call git-commit-tree). We let
the hook alter the file as it sees fit and we don't bother to look at
its content again until the commit succeeded and we need the subject
for the reflog update.

If we apply a hunk in either direction this may change the file's
status. For example if a file is completely unstaged, and has at
least two hunks in it and the user stages one hunk the file will
change from "Modified, not staged" to "Portions staged for commit".
Resetting the file path causes our trace on this variable to fire;
that trace is used to update the file header in the diff viewer to
the file's current status.

Often users setup a few source files and get a project rolling
before they create a Git repository for it. In such cases the
core Git tools allow users to initialize a new repository by
simply running `git init` at the desired root level directory.
We need to allow the same situation in git-gui; if the user is
trying to make a new repository we should let them do that to any
location they chose. If the directory already exists and already
has files contained within it we still should allow the user to
create a repository there. However we still need to disallow
creating a repository on top of an existing repository.

On Windows its better to use a shortcut (.lnk file) over a batch

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.

Windows .lnk files, using the "Start in" property of these files
to indicate the working directory of the repository the user wants

10 entries it will be truncated by removing one of the older entries.
Only repositories that are opened through the repository chooser

to have a way to easily return to the same directory via their shell.

Henrik came up with this alternative logo for gitweb and posted
it on his blog:
http://henrik.nyh.se/2007/06/alternative-git-logo-and-favicon
The msysGit port uses his logo within some of their components,
and frankly it looks better here in git-gui for our repository
setup wizard screen. The logo fits quite nicely along the left
edge of our window, leaving significantly more vertical space
for things like the git-fetch console output.
Because the logo changes the layout charateristics of the setup
window I also needed to adjust some of the padding for our widgets
and stop using a fixed width window size. We now let Tk compute
the correct size of the main window whenever the layout changes,
and drop the window into roughly the upper left 1/3 of the desktop
so its not quite centered but is likely to be far enough away from
any sort of task bars/menu bars/docks that the user may have along

If the console finishes displaying its output and is "done" but

horizontal or vertical scrollbar to the window when the text
widget decides it cannot draw all glyphs on screen.
We need to delay deleting the window namespace until we know
the window is not going to ever be used again. This occurs if
we are done receiving output, the command is successful and the
window is closed, or if the window is open and the user chooses
to close the window after the command has completed.
