2009-11-13add -i, send-email, svn, p4, etc: use "git var GIT_EDITOR"Libravatar Jonathan Nieder1-2/+1
Use the new "git var GIT_EDITOR" feature to decide what editor to use, instead of duplicating its logic elsewhere. This should make the behavior of commands in edge cases (e.g., editor names with spaces) a little more consistent.

2009-10-27add-interactive: handle deletion of empty filesLibravatar Jeff King1-5/+13
Usually we show deletion as a big hunk deleting all of the file's text. However, for files with no content, the diff shows just the 'deleted file mode ...' line. This patch cause "add -p" (and related commands) to recognize that line and explicitly ask about deleting the file. We only add the "stage this deletion" hunk for empty files, since other files will already ask about the big content deletion hunk. We could also change those files to simply display "stage this deletion", but showing the actual deleted content is probably what an interactive user wants.

2009-08-15Implement 'git stash save --patch'Libravatar Thomas Rast1-2/+12
This adds a hunk-based mode to git-stash. You can select hunks from the difference between HEAD and worktree, and git-stash will build a stash that reflects these changes. The index state of the stash is the same as your current index, and we also let --patch imply --keep-index. Note that because the selected hunks are rolled back from the worktree but not the index, the resulting state may appear somewhat confusing if you had also staged these changes. This is not entirely satisfactory, but due to the way stashes are applied, other solutions would require a change to the stash format.

2009-08-15Implement 'git checkout --patch'Libravatar Thomas Rast1-0/+61
This introduces a --patch mode for git-checkout. In the index usage git checkout --patch -- [files...] it lets the user discard edits from the <files> at the granularity of hunks (by selecting hunks from 'git diff' and then reverse applying them to the worktree). We also accept a revision argument. In the case git checkout --patch HEAD -- [files...] we offer hunks from the difference between HEAD and the worktree, and reverse applies them to both index and worktree, allowing you to discard staged changes completely. In the non-HEAD usage git checkout --patch <revision> -- [files...] it offers hunks from the difference between the worktree and <revision>. The chosen hunks are then applied to both index and worktree. The application to worktree and index is done "atomically" in the sense that we first check if the patch applies to the index (it should always apply to the worktree). If it does not, we give the user a choice to either abort or apply to the worktree anyway. Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-08-15Implement 'git reset --patch'Libravatar Thomas Rast1-4/+53
This introduces a --patch mode for git-reset. The basic case is git reset --patch -- [files...] which acts as the opposite of 'git add --patch -- [files...]': it offers hunks for *un*staging. Advanced usage is git reset --patch <revision> -- [files...] which offers hunks from the diff between the index and <revision> for forward application to the index. (That is, the basic case is just <revision> = HEAD.) Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-08-15add -p: do not attempt to coalesce mode changesLibravatar Thomas Rast1-0/+4
In 0392513 (add-interactive: refactor mode hunk handling, 2009-04-16), we merged the interaction loops for mode changes and hunk staging. This was fine at the time, because 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02) removed hunk coalescing. However, in 7a26e65 (Revert "git-add--interactive: remove hunk coalescing", 2009-05-16), we resurrected it. Since then, the code would attempt in vain to merge mode changes with diff hunks, corrupting both in the process. We add a check to the coalescing loop to ensure it only looks at diff hunks, thus skipping mode changes.

2009-08-14git-apply--interactive: Refactor patch mode codeLibravatar Thomas Rast1-27/+55
This makes some aspects of the 'git add -p' loop configurable (within the code), so that we can later reuse git-add--interactive for other similar tools. Most fields are fairly straightforward, but APPLY gets a subroutine (instead of just a string a la 'apply --cached') so that we can handle 'checkout -p', which will need to atomically apply the patch twice (index and worktree).

2009-04-19add-interactive: refactor mode hunk handlingLibravatar Jeff King1-43/+21
The original implementation considered the mode separately from the rest of the hunks, asking about it outside the main hunk-selection loop. This patch instead places a mode change as the first hunk in the loop. This has two advantages: 1. less duplicated code (since we use the main selection loop). This also cleans up an inconsistency, which is that the main selection loop separates options with a comma, whereas the mode prompt used slashes. 2. users can now skip the mode change and come back to it, search for it (via "/mode"), etc, as they can with other hunks. To facilitate this, each hunk is now marked with a "type". Mode hunks are not considered for splitting (which would make no sense, and also confuses the split_hunk function), nor are they editable. In theory, one could edit the mode lines and change to a new mode. In practice, there are only two modes that git cares about (0644 and 0755), so either you want to move from one to the other or not (and you can do that by staging or not staging).

2009-02-08add -p: get rid of Git.pm warnings about unitialized valuesLibravatar Stephan Beyer1-1/+2
After invoking git add -p I always got the warnings: Use of uninitialized value $_[3] in exec at Git.pm line 1282. Use of uninitialized value $args[2] in join or string at Git.pm line 1264. A bisect showed that these warnings occur in a301973 "add -p: print errors in separate color" the first time. They can be reproduced by setting color.ui (or color.interactive) to "auto" and unsetting color.interactive.help and color.interactive.error. I am using Perl 5.10.0. The reason of the warning is that color.interactive.error defaults to color.interactive.help which defaults to nothing in the specific codepath. It defaults to 'red bold' some lines above which could lead to the wrong assumption that it always defaults to 'red bold' now. This patch lets it default to 'red bold', blowing the warnings away.

2008-07-02git-add--interactive: manual hunk editing modeLibravatar Thomas Rast1-0/+119
Adds a new option 'e' to the 'add -p' command loop that lets you edit the current hunk in your favourite editor. If the resulting patch applies cleanly, the edited hunk will immediately be marked for staging. If it does not apply cleanly, you will be given an opportunity to edit again. If all lines of the hunk are removed, then the edit is aborted and the hunk is left unchanged. Applying the changed hunk(s) relies on Johannes Schindelin's new --recount option for git-apply. Note that the "real patch" test intentionally uses (echo e; echo n; echo d) | git add -p even though the 'n' and 'd' are superfluous at first sight. They serve to get out of the interaction loop if git add -p wrongly concludes the patch does not apply. Many thanks to Jeff King <peff@peff.net> for lots of help and suggestions.

When a path is examined in the patch subcommand, any mode changes in the file are given to use in the diff header by git-diff. If no hunks are staged, then we throw out that header and do not touch the path. But if _any_ hunks are staged, we use the header, and the mode is changed together with the contents. Since the 'p'atch command should just be dealing with hunks that are shown to the user, it makes sense to just ignore mode changes entirely. We do squirrel away the mode, though, since the next patch will allow users to select the mode update separately.

2008-01-06add--interactive: allow diff colors without interactive colorsLibravatar Jeff King1-24/+15
Users with color.diff set to true/auto will not see color in "git add -i" unless they also set color.interactive. This changes the semantics of color.interactive to control only the coloring of the interaction aspect of the command and let color.diff to control the color of hunk picker, which would arguably be more convenient. Old $use_color variable is now renamed to $menu_use_color to make it clear that it is about coloring the interaction. The "colored" subroutine now checks if the passed color is defined, instead of checking $use_color variable, to decide if the lines should be colored. The various variables that define colors for different parts of the output are set or unset depending on the setting of color.interactive and color.diff configuration variables.

2007-12-08Teach "git add -i" to colorize whitespace errorsLibravatar Wincent Colaiuta1-39/+34
Rather than replicating the colorization logic of "git diff-files" we rely on "git diff-files" itself. This guarantees consistent colorization in and outside "git add -i". Seeing as speed is not a concern here (the bottleneck is how fast the user can read, not how fast "git diff-files" runs) we do this by actually running it twice, once without color and once with. In this way as the whitespace colorization provided by "git diff-files" evolves (per-path attributes, new classes of whitespace error), "git add -i" will automatically benefit from it and stay in synch. Also, by working with two sets of diff output (an uncolorized one for internal processing and a colorized one for display only) we minimize the risk of regressions because the changes required to implement this are minimally invasive.

2007-12-05Color support for "git-add -i"Libravatar Junio C Hamano1-20/+99
This is mostly lifted from earlier series by Dan Zwell, but updated to use "git config --get-color" and "git config --get-colorbool" to make it simpler and more consistent with commands written in C. A new configuration color.interactive variable is like color.diff and color.status, and controls if "git-add -i" uses color. A set of configuration variables, color.interactive.<slot>, are used to define what color is used for the prompt, header, and help text. For perl scripts, Git.pm provides $repo->get_color() method, which takes the slot name and the default color, and returns the terminal escape sequence to color the output text. $repo->get_colorbool() method can be used to check if color is set to be used for a given operation.
