Johannes Sixt	c7f7457026	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.

Johannes Sixt	fa6b5b3944	git-gui: Fix "Stage/Unstage Line" with one line of context. To "Stage/Unstage Line" we construct a patch that contains exactly one change (either addition or removal); the hunk header was forged by counting the old side and adjusting the count by +/-1 for the new side. But when we counted the context we never counted the changed line itself. If the hunk had only one removal line and one line of context, like this: @@ -1,3 +1,2 @@ context 1 -removal context 2 We had constructed this patch: @@ -1,2 +1,1 @@ context 1 -removal context 2 which does not apply because git apply deduces that it must apply at the end of the file. ("context 2" is considered garbage and ignored.) The fix is that removal lines must be counted towards the context of the old side.

Johannes Sixt	5821988f97	git-gui: Implement "Stage/Unstage Line" 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 Hunk" case. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Shawn O.

Shawn O. Pearce	a41e45ea1c	git-gui: Refresh file status description after hunk application 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. Noticed by Johannes Sixt.

Shawn O. Pearce	a4750dd266	git-gui: Handle file mode changes (644->755) in diff viewer Johannes Sixt pointed out the diff headers "old mode ..." and "new mode ..." were not being parsed properly by git-gui.

Shawn O. Pearce	31bb1d1b2d	git-gui: Paper bag fix missing translated strings The Tcl expression "[append [mc Foo] Bar]" does not return the string "FooBar" after translation; instead it is setting the variable Foo to the value Bar, or if Foo is already defined it is appending Bar onto the end of it. This is not what we wanted to have happen here. Tcl's join function is actually the correct function but its default joinStr argument is a single space. Unfortunately all of our call sites do not want an extra space added to their string. So we need a small wrapper function to make the call to join with an empty join string. In C this is (roughly) the job of the strcat function. Since strcat is not yet used at the global level it is a reasonable name to use here. Signed-off-by: Shawn O.

Shawn O. Pearce	3b9dfde3d6	git-gui: Assume untracked directories are Git submodules If `git ls-files --others` returned us the name of a directory then it is because Git has decided that this directory itself contains a valid Git repository and its files shouldn't be listed as untracked for this repository. In such a case we should label the object as a Git repository and not just as a directory. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago

Christian Stimming	1ac17950e9	Mark strings for translation. The procedure [mc ...] will translate the strings through msgcat. Strings must be enclosed in quotes, not in braces, because otherwise xgettext cannot extract them properly, although on the Tcl side both delimiters would work fine.

Shawn O. Pearce	6eb420ef61	git-gui: Always disable the Tcl EOF character when reading On Windows (which includes Cygwin) Tcl defaults to leaving the EOF character of input file streams set to the ASCII EOF character, but if that character were to appear in the data stream then Tcl will close the channel early. So we have to disable eofchar on Windows. Since the default is disabled on all platforms except Windows, we can just disable it everywhere to prevent any sort of read problem. Signed-off-by: Shawn O.

Shawn O. Pearce	0b81261622	git-gui: Always use absolute path to all git executables Rather than making the C library search for git every time we want to execute it we now search for the main git wrapper at startup, do symlink resolution, and then always use the absolute path that we found to execute the binary later on. This should save us some cycles, especially on stat challenged systems like Cygwin/Win32. While I was working on this change I also converted all of our existing pipes ([open "\| git ..."]) to use two new pipe wrapper functions. These functions take additional options like --nice and --stderr which instructs Tcl to take special action, like running the underlying git program through `nice` (if available) or redirect stderr to stdout for capture in Tcl.

Shawn O. Pearce	699d5601f5	git-gui: Refactor our ui_status_value update technique I'm really starting to dislike global variables. The ui_status_value global varible is just one of those that seems to appear in a lot of code and in many cases we didn't even declare it "global" within the proc that updates it so we haven't always been getting all of the updates we expected to see. This change introduces two new global procs: ui_status $msg; # Sets the status bar to show $msg. ui_ready; # Changes the status bar to show "Ready." The second (special) form is used because we often update the area with this message once we are done processing a block of work and want the user to know we have completed it. I'm not fixing the cases that appear in lib/branch.tcl right now as I'm actually in the middle of a huge refactoring of that code to support making a detached HEAD checkout. Signed-off-by: Shawn O.

Shawn O. Pearce	b8848f7753	git-gui: Allow as few as 0 lines of diff context Johannes Sixt pointed out that dropping to 0 lines of context does allow the user to get more fine-grained hunk selection, especially since we don't currently support "highlight and apply (or revert)".

Shawn O. Pearce	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. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
