git-gui: Adapt discovery of oguilib to execdir 'libexec/git-core'
The new execdir is two levels below the root directory, while
the old execdir 'bin' was only one level below. This commit
adapts the discovery of oguilib that uses relative paths
accordingly. We determine whether we have the extra level in the same
way in which the Makefile defines sharedir, i.e. whether the last
directory part is 'git-core'.

git-gui (Windows): Change wrapper to execdir 'libexec/git-core'
git-gui needs bindir in PATH to be able to run 'git'. bindir
however is not necessarily in PATH if started directly through a
Windows shortcut. Therefore, we used to add the directory
git-gui is located in. But with the new 'libexec/git-core'
layout this directory is no longer identical to bindir.
This commit modifies the wrapper script to discover the bindir
and add it to PATH.

git-gui: Correct installation of library to be $prefix/share

git-gui: Fix gitk search in $PATH to work on Windows
Back in 15430be5a1 ("Look for gitk in $PATH, not $LIBEXEC/git-core")
git-gui learned to use [_which gitk] to locate where gitk's script
is as Git 1.6 will install gitk to $prefix/bin (in $PATH) and all
of the other tools are in $gitexecdir.
This failed on Windows because _which adds the ".exe" suffix as it
searches for the program on $PATH, under the assumption that we can
only execute something from Tcl if it is a proper Windows executable.
When scanning for gitk on Windows we need to omit the ".exe" suffix.

git-gui: "Stage Line": Treat independent changes in adjacent lines better
Assume that we want to commit these states:
Old state == HEAD Intermediate state New state
--------------------------------------------------------
context before context before context before
old 1 new 1 new 1
old 2 old 2 new 2
context after context after context after
that is, want to commit two changes in this order:
1. transform "old 1" into "new 1"
2. transform "old 2" into "new 2"
[This discussion and this patch is about this very case and one other case
as outlined below; any other intermediate states that one could imagine are
not affected by this patch.]
Now assume further, that we have not staged and commited anything, but we
have already changed the working file to the new state. Then we will see
this hunk in the "Unstaged Changes":
@@ -1,4 +1,4 @@
context before
-old 1
-old 2
+new 1
+new 2
context after
The obvious way to stage the intermediate state is to apply "Stage This
Line" to "-old 1" and "+new 1". Unfortunately, this resulted in this
intermediate state:
context before
old 2
new 1
context after
which is not what we wanted. In fact, it was impossible to stage the
intermediate state using "Stage Line". The crux was that if a "+" line was
staged, then the "-" lines were converted to context lines and arranged
*before* the "+" line in the forged hunk that we fed to 'git apply'.
With this patch we now treat "+" lines that are staged differently. In
particular, the "-" lines before the "+" block are moved *after* the
staged "+" line. Now it is possible to get the correct intermediate state
by staging "-old 1" and "+new 1". Problem solved.
But there is a catch.
Noticing that we didn't get the right intermediate state by staging
"-old 1" and "+new 1", we could have had the idea to stage the complete
hunk and to *unstage* "-old 2" and "+new 2". But... the result is the same.
The reason is that there is the exact symmetric problem with unstaging the
last "-" and "+" line that are in adjacent blocks of "-" and "+" lines.
This patch does *not* change the way in which "-" lines are *unstaged*.
Why? Because if we did (i.e. move "+" lines before the "-" line after
converting them to context lines), then it would be impossible to stage
this intermediate state:
context before
old 1
new 2
context after
that is, it would be impossible to stage the two independet changes in the
opposite order.
Let's look at this case a bit further: The obvious way to get this
intermediate state would be to apply "Stage This Line" to "-old 2" and
"+new 2". Before this patch, this worked as expected. With this patch, it
does not work as expected, but it can still be achieved by first staging
the entire hunk, then *unstaging* "-old 1" and "+new 1".
In summary, this patch makes a common case possible, at the expense that
a less common case is made more complicated for the user.

In Git 1.6 and later gitk is in $prefix/bin while git-gui and all

This adds a context menu entry below "Stage/Unstage Hunk" that stages or
unstages just the line under the mouse pointer.
This is by itself useful, for example, if there are unrelated changes in
the same hunk and the hunk cannot be split by reducing the context.
The feature can also be used to split a hunk by staging a number of
additions (or unstaging a number of removals) until there are enough
context lines that the hunk gets split.
The implementation reads the complete hunk that the line lives in, and
constructs a new hunk by picking existing context lines, removing unneeded
change lines and transforming other change lines to context lines. The
resulting hunk is fed through 'git apply' just like in the "Stage/Unstage

on to the next filename in the list and display that diff instead of a
blank diff pane. If the selected file was at the end of the list, the

Often new Git users want to know what commands git-gui uses to make

what git-gui does in response to GUI actions. Showing the direct
commands being executed is easy enough to implement but this is of
little value to end-users because git-gui frequently directly calls
plumbing, not porcelain.
Since the code is already written and tested, its fairly harmless

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.

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.

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.

git-gui: Automatically spell check commit messages as the user types
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.

In the multiple message case we remove the word "messages" from the
statistics output of msgfmt as it looks cleaner on the tty when you
are watching the build process. However we failed to strip the word
"message" when only 1 message was found to be untranslated or fuzzy,
as msgfmt does not produce the 's' suffix.

git-gui: Make the statistics of po2msg match those of msgfmt
The strings we were showing from po2msg didn't exactly match those
of msgfmt's --statistics output so we didn't show quite the same
results when building git-gui's message files. Now we're closer
to what msgfmt shows (at least for an en_US locale) so the make
output matches.
I noticed that the fuzzy translation count is off by one for the
current po/zh_cn.po file. Not sure why and I'm not going to try
and debug it at this time as the po2msg is strictly a fallback,
users building from source really should prefer msgfmt.

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
those are too useful to give up.
