"git add -p" learned a new mode that allows the user to revisit a file that was already dealt with. * aa/add-p-no-auto-advance: add-patch: allow interfile navigation when selecting hunks add-patch: allow all-or-none application of patches add-patch: modify patch_update_file() signature interactive -p: add new `--auto-advance` flag
2026-02-17add-patch: allow interfile navigation when selecting hunksAbraham Samuel Adekunle
After deciding on all hunks in a file, the interactive session advances automatically to the next file if there is another, or the process ends. Now using the `--no-auto-advance` flag with `--patch`, the process does not advance automatically. A user can choose to go to the next file by pressing '>' or the previous file by pressing '<', before or after deciding on all hunks in the current file. After all hunks have been decided in a file, the user can still rework with the file by applying the options available in the permit set for that hunk, and after all the decisions, the user presses 'q' to submit. After all hunks have been decided, the user can press '?' which will show the hunk selection summary in the help patch remainder text including the total hunks, number of hunks marked for use and number of hunks marked for skip. This feature is enabled by passing the `--no-auto-advance` flag to `--patch` option of the subcommands add, stash, reset, and checkout.

2026-01-09add -p: show user's hunk decision when selecting hunksAbraham Samuel Adekunle
When a user is interactively deciding which hunks to use or skip for staging, unstaging, stashing etc, there is no way to know the decision previously chosen for a hunk when navigating through the previous and next hunks using K/J respectively. Improve the UI to explicitly show if a user has previously decided to use a hunk (by pressing 'y') or skip the hunk (by pressing 'n'). This will improve clarity when and aid the navigation process for the user.

Options a and d stage and unstage all undecided hunks towards the bottom of the array of hunks, respectively, and then roll over to the very first hunk.

2025-10-06add-patch: let options y, n, j, and e roll over to next undecidedRené Scharfe
The options y, n, and e mark the current hunk as decided. If there's another undecided hunk towards the bottom of the hunk array they go there. If there isn't, but there is another undecided hunk towards the top then they go to the very first hunk, no matter if it has already been decided on. The option j does basically the same move. Technically it is not allowed if there's no undecided hunk towards the bottom, but the variable "permitted" is never reset, so this permission is retained from the very first hunk. That may a bug, but this behavior is at least consistent with y, n, and e and arguably more useful than refusing to move. Improve the roll-over behavior of these four options by moving to the first undecided hunk instead of hunk 1, consistent with what they do when not rolling over. Also adjust the error message for j, as it will only be shown if there's no other undecided hunk in either direction.

The variable "permitted" is not reset after moving to a different hunk, so it only accumulates permission and doesn't necessarily reflect those of the current hunk. This may be a bug, but is actually useful with the option J, which can be used at the last hunk to roll over to the first hunk. Make this particular behavior official.

2025-09-25add-patch: update hunk splitability after editingPhillip Wood
If, when the user edits a hunk, they change deletion lines into context lines or vice versa, then the number of hunks that the edited hunk can be split into may differ from the unedited hunk. This means that so we should recalculate `hunk->splittable_into` after the hunk has been edited. In practice users are unlikely to hit this bug as it is doubtful that a user who has edited a hunk will split it afterwards.

2025-09-25add -p: mark split hunks as undecidedPhillip Wood
When a hunk is split, each of the new hunks inherits whether it is selected or not from the original hunk. If a selected hunk is split all of the new hunks are marked as "selected" and the user is only prompted with the first of the split hunks. The user is not asked whether or not they wish to select the rest of the new hunks. This means that if they wish to deselect any of the new hunks apart from the first one they have to navigate back to the hunk they want to deselect before they can deselect it. This is unfortunate as the user is presumably splitting the original hunk because they only want to select some sub-set of it. Instead mark all the new hunks as "undecided" so that the user is prompted whether they wish to select each one in turn. In the case where the user only wants to change the selection of the first of the split hunks they will now have to do more work re-selecting the remaining split hunks. However, changing the selection of any of the other newly created hunks is now much simpler as the user no-longer has to navigate back to them in order to change their selected state.

2025-09-08add-interactive: manually fall back color config to color.uiJeff King
Color options like color.interactive and color.diff should fall back to the value of color.ui if they aren't set. In add-interactive, we check the specific options (e.g., color.diff) via repo_config_get_value(), which does not depend on the main command having loaded any color config via the git_config() callback mechanism. But then we call want_color() on the result; if our specific config is unset then that function uses the value of git_use_color_default. That variable is typically set from color.ui by the git_color_config() callback, which is called by the main command in its own git_config() callback function. This works fine for "add -p", whose add_config() callback calls into git_color_config(). But it doesn't work for other commands like "checkout -p", which is otherwise unaware of color at all. People tend not to notice because the default is "auto", and that's what they'd set color.ui to as well. But something like: git -c color.ui=false checkout -p should disable color, and it doesn't. This regression goes back to 0527ccb1b5 (add -i: default to the built-in implementation, 2021-11-30). In the perl version we got the color config from "git config --get-colorbool", which did the full lookup for us. The obvious fix is for git-checkout to add a call to git_color_config() to its own config callback. But we'd have to do so for every command with this problem, which is error-prone. Let's see if we can fix it more centrally. It is tempting to teach want_color() to look up the value of repo_config_get_value("color.ui") itself. But I think that would have disastrous consequences. Plumbing commands, especially older ones, avoid porcelain config like "color.*" by simply not parsing it in their config callbacks. Looking up the value of color.ui under the hood would undermine that. Instead, let's do that lookup in the add-interactive setup code. We're already demand-loading other color config there, which is probably fine (even in a plumbing command like "git reset", the interactive mode is inherently porcelain-ish). That catches all commands that use the interactive code, whether they were calling git_color_config() themselves or not.

2025-09-08add-interactive: respect color.diff for diff coloringJeff King
The old perl git-add--interactive.perl script used the color.diff config option to decide whether to color diffs (and if not set, it fell back to the value of color.ui via git-config's --get-colorbool option). When we switched to the builtin version, this was lost: we respect only color.ui. So for example: git -c color.diff=false add -p would color the diff, even when it should not. The culprit is this line in add-interactive.c's parse_diff(): if (want_color_fd(1, -1)) That "-1" means "no config has been set", which causes it to fall back to the color.ui setting. We should instead be passing the value of color.diff. But the problem is that we never even parse that config option! Instead the builtin interactive code parses only the value of color.interactive, which is used for prompts and other messages. One could perhaps argue that this should cover interactive diff coloring, too, but historically it did not. The perl script treated color.interactive and color.diff separately. So we should grab the values for both, keeping separate fields in our add_i_state variable, rather than a single use_color field. We also load individual color slots (e.g., color.interactive.prompt), leaving them as the empty string when color is disabled. This happens via the init_color() helper in add-interactive, which checks that use_color field. Now that there are two such fields, we need to pass the appropriate one for each color. The colors are mostly easy to divide up; color.interactive.* follows color.interactive, and color.diff.* follows color.diff. But the "reset" color is tricky. It is used for both types of coloring, but the two can be configured independently. So we introduce two separate reset colors, and use each in the appropriate spot. There are two new tests. The first enables interactive prompt colors but disables color.diff. We should see a colored prompt but not a colored diff, showing that we are now respecting color.diff (and not color.interactive or color.ui). The second does the opposite. We disable color.interactive but turn on color.diff with a custom fragment color. When we split a hunk, the interactive code has to re-color the hunk header, which lets us check that we correctly loaded the color.diff.frag config based on color.diff, not color.interactive.

2025-07-29add-patch: add diff.context command line overridesLeon Michalak
This patch compliments the previous commit, where builtins that use add-patch infrastructure now respect diff.context and diff.interHunkContext file configurations. In particular, this patch helps users who don't want to set persistent context configurations or just want a way to override them on a one-time basis, by allowing the relevant builtins to accept corresponding command line options that override the file configurations. This mimics commands such as diff and log, which allow for both context file configuration and command line overrides.

Make the print command trigger the pager when invoked using a capital 'P', to make it easier for the user to review long hunks. Note that if the PAGER ends unexpectedly before we've been able to send the payload, perhaps because the user is not interested in the whole thing, we might receive a SIGPIPE, which would abruptly and unexpectedly terminate the interactive session for the user. Therefore, we need to ignore a possible SIGPIPE signal. Add a test for this, in addition to the test for normal operation. For the SIGPIPE test, we need to make sure that we completely fill the operating system's buffer, otherwise we might not trigger the SIGPIPE signal. The normal size of this buffer in different OSs varies from a few KBs to 1MB. Use a payload large enough to guarantee that we exceed this limit.

2024-07-20add-patch: handle splitting hunks with diff.suppressBlankEmptyPhillip Wood
When "add -p" parses diffs, it looks for context lines starting with a single space. But when diff.suppressBlankEmpty is in effect, an empty context line will omit the space, giving us a true empty line. This confuses the parser, which is unable to split based on such a line. It's tempting to say that we should just make sure that we generate a diff without that option. However, although we do not parse hunks that the user has manually edited with parse_diff() we do allow the user to split such hunks. As POSIX calls the decision of whether to print the space here "implementation-defined" we need to handle edited hunks where empty context lines omit the space. So let's handle both cases: a context line either starts with a space or consists of a totally empty line by normalizing the first character to a space when we parse them. Normalizing the first character rather than changing the code to check for a space or newline will hopefully future proof against introducing similar bugs if the code is changed.

2024-05-22add-patch: enforce only one-letter response to promptsJunio C Hamano
In a "git add -p" session, especially when we are not using the single-key mode, we may see 'qa' as a response to a prompt (1/2) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]? and then just do the 'q' thing (i.e. quit the session), ignoring everything other than the first byte. If 'q' and 'a' are next to each other on the user's keyboard, there is a plausible chance that we see 'qa' when the user who wanted to say 'a' fat-fingered and we ended up doing the 'q' thing instead. As we didn't think of a good reason during the review discussion why we want to accept excess letters only to ignore them, it appears to be a safe change to simply reject input that is longer than just one byte. The two exceptions are the 'g' command that takes a hunk number, and the '/' command that takes a regular expression. They have to be accompanied by their operands (this makes me wonder how users who set the interactive.singlekey configuration feed these operands---it turns out that we notice there is no operand and give them another chance to type the operand separately, without using single key input this time), so we accept a string that is more than one byte long. Keep the "use only the first byte, downcased" behaviour when we ask yes/no question, though. Neither on Qwerty or on Dvorak, 'y' and 'n' are not close to each other.

When color is enabled, the first letter of each word is changed to a highlight color to signal that the first letter could be used as a command. Without color, brackets ("[]") are used around these first letters. This behavior was not previously tested directly in t3701, so add a test for it now. Since we use 'git add -i >actual <input' without 'force_color', the color system recognizes that colors are not available on stdout and will be disabled by default. This test would reproduce correctly with or without the fix in the previous commit to make sure that color.ui is respected in 'git add'.

2023-06-12add: check color.ui for interactive addDerrick Stolee
When 'git add -i' and 'git add -p' were converted to a builtin, they introduced a color bug: the 'color.ui' config setting is ignored. The included test demonstrates an example that is similar to the previous test, which focuses on customizing colors. Here, we are demonstrating that colors are not being used at all by comparing the raw output and the color-decoded version of that output. The fix is simple, to use git_color_default_config() as the fallback for git_add_config(). A more robust change would instead encapsulate the git_use_color_default global in methods that would check the config setting if it has not been initialized yet. Some ideas are being discussed on this front [1], but nothing has been finalized. [1] https://lore.kernel.org/git/pull.1539.git.1685716420.gitgitgadget@gmail.com/ This test case naturally bisects down to 0527ccb1b55 (add -i: default to the built-in implementation, 2021-11-30), but the fix makes it clear that this would be broken even if we added the config to use the builtin earlier than this.

2023-03-09add-patch: handle "* Unmerged path" linesJeff King
When we generate a diff with --cached, unmerged entries have no oid for their index entry: $ git diff-index --abbrev --cached HEAD :100644 000000 f719efd 0000000 U my-conflict So when we are asked to produce a patch, since we only have one side, we just emit a special message: $ git diff-index --cached -p HEAD * Unmerged path my-conflict This confuses interactive-patch modes that look at cached diffs. For example: $ git reset -p BUG: add-patch.c:498: diff starts with unexpected line: * Unmerged path my-conflict Making things even more confusing, you'll get that error only if the unmerged entry is alphabetically the first changed file. Otherwise, we simply stick the unrecognized line to the end of the previous hunk. There it's mostly harmless, as it eventually gets fed back to "git apply", which happily ignores it. But it's still shown to the user attached to the hunk, which is wrong. So let's handle these lines as a noop. There's not really anything useful to do with a conflicted merge in this case, and that's what we do for other cases like "add -p". There we get a "diff --cc" line, which we accept as starting a new file, but we refuse to use any of its hunks (their headers start with "@@@" and not "@@ ", so we silently ignore them). It seems like simply recognizing the line and continuing in our parsing loop would work. But we actually need to run the rest of the loop body to handle matching up our colored/filtered output. But that code assumes that we have some active file_diff we're working on. So instead, we'll just insert a dummy entry into our array. This ends up the same as if we saw a "diff --cc" line (a file with no hunks).

Fix a few miscellaneous cases where: - We lost the "git" exit code via "git ... | grep" - Likewise by having a $(git) argument to git itself - Used "test -z" to check that a command emitted no output, we can use "test_must_be_empty" and &&-chaining instead.

2023-02-06add: remove "add.interactive.useBuiltin" & Perl "git add--interactive"Ævar Arnfjörð Bjarmason
Since [1] first released with Git v2.37.0 the built-in version of "add -i" has been the default. That built-in implementation was added in [2], first released with Git v2.25.0. At this point enough time has passed to allow for finding any remaining bugs in this new implementation, so let's remove the fallback code. As with similar migrations for "stash"[3] and "rebase"[4] we're keeping a mention of "add.interactive.useBuiltin" in the documentation, but adding a warning() to notify any outstanding users that the built-in is now the default. As with [5] and [6] we should follow-up in the future and eventually remove that warning. 1. 0527ccb1b55 (add -i: default to the built-in implementation, 2021-11-30) 2. f83dff60a78 (Start to implement a built-in version of `git add --interactive`, 2019-11-13) 3. 8a2cd3f5123 (stash: remove the stash.useBuiltin setting, 2020-03-03) 4. d03ebd411c6 (rebase: remove the rebase.useBuiltin setting, 2019-03-18) 5. deeaf5ee077 (stash: remove documentation for `stash.useBuiltin`, 2022-01-27) 6. 9bcde4d5314 (rebase: remove transitory rebase.useBuiltin setting & env, 2021-03-23) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-09-01add -p: ignore dirty submodulesJohannes Schindelin
Thanks to always running `diff-index` and `diff-files` with the `--numstat` option (the latter with `--ignore-submodules=dirty`) before even generating any real diff to parse, the Perl version of `git add -p` simply ignored dirty submodules and does not even offer them up for staging. However, the built-in variant did not use that flag because it tries to run only one `diff` command, skipping the unneeded `diff-index`/`diff-files` invocation of the Perl variant and therefore only faithfully recapitulates what the Perl code does once it _does_ generate and parse the real diff. This causes a problem when running the built-in `add -p` with `diff-so-fancy` because that diff colorizer always inserts an empty line before the diff header to ensure that it produces 4 lines as expected by `git add -p` (the equivalent of the non-colorized `diff`, `index`, `---` and `+++` lines). But `git diff-files` does not produce any `index` line for dirty submodules. The underlying problem is not even the discrepancy in lines, but that `git add -p` presents diffs for dirty submodules: there is nothing that _can_ be staged for those. Let's fix that bug, and teach the built-in `add -p` to ignore dirty submodules, too. This _incidentally_ also fixes the `diff-so-fancy` problem ;-) Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-09-01add -p: gracefully handle unparseable hunk headers in colored diffsJohannes Schindelin
In https://lore.kernel.org/git/ecf6f5be-22ca-299f-a8f1-bda38e5ca246@gmail.com, Phillipe Blain reported that the built-in `git add -p` command fails when asked to use [`diff-so-fancy`][diff-so-fancy] to colorize the diff. The reason is that this tool produces colored diffs with a hunk header that does not contain any parseable `@@ ... @@` line range information, and therefore we cannot detect any part in that header that comes after the line range. As proposed by Phillip Wood, let's take that for a clear indicator that we should show the hunk headers verbatim. This is what the Perl version of the interactive `add` command did, too.

2022-09-01add -p: detect more mismatches between plain vs colored diffsJohannes Schindelin
When parsing the colored version of a diff, the interactive `add` command really relies on the colored version having the same number of lines as the plain (uncolored) version. That is an invariant. We already have code to verify correctly when the colored diff has less lines than the plain diff. Modulo an off-by-one bug: If the last diff line has no matching colored one, the code pretends to succeed, still. To make matters worse, when we adjusted the test in 1e4ffc765db (t3701: adjust difffilter test, 2020-01-14), we did not catch this because `add -p` fails for a _different_ reason: it does not find any colored hunk header that contains a parseable line range. If we change the test case so that the line range _can_ be parsed, the bug is exposed. Let's address all of the above by - fixing the off-by-one, - adjusting the test case to allow `add -p` to parse the line range - making the test case more stringent by verifying that the expected error message is shown Also adjust a misleading code comment about the now-fixed code.
