Russell Belfer 8d09efa2 2014-04-22T12:33:27 Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.
Russell Belfer 12e422a0 2014-04-21T16:08:05 Some doc and examples/diff.c changes I was playing with "git diff-index" and wanted to be able to emulate that behavior a little more closely with the diff example. Also, I wanted to play with running `git_diff_tree_to_workdir` directly even though core Git doesn't exactly have the equivalent, so I added a command line option for that and tweaked some other things in the example code. This changes a minor output thing in that the "raw" print helper function will no longer add ellipses (...) if the OID is not actually abbreviated.

Brian Gesiak 0d3c8a9d 2014-03-05T13:06:31 examples/diff: Add minimal, patience diff options. - Add minimal, patience diff options to diff example. libgit2 `diff_xdiff.git_xdiff_init` already supports these flags, so no additional change is necessary. - Remove minimal and patience flag addition from project list.

Carlos Martín Nieto c44820c6 2013-10-31T23:42:50 A few formatting changes for rocco I'm not too happy about manually inserting < and > but those get output as html tags otherwise.
Ben Straub 85c6730c 2013-10-31T14:35:32 Format comments for use with docco
Russell Belfer 66902d47 2013-10-29T18:30:49 Extract common example helpers and reorg examples This reorganizes a few of the examples so that the main function comes first with the argument parsing extracted into a helper that can come at the end of the file (so the example focuses more on the use of libgit2 instead of command line support). This also creates a shared examples/common.[ch] so that useful helper funcs can be shared across examples instead of repeated.
Russell Belfer 3b5f7954 2013-10-21T13:42:42 Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.
Russell Belfer 10672e3e 2013-10-15T15:10:07 Diff API cleanup This lays groundwork for separating formatting options from diff creation options. This groups the formatting flags separately from the diff list creation flags and reorders the options. This also tweaks some APIs to further separate code that uses patches from code that just looks at git_diffs.
Russell Belfer 3ff1d123 2013-10-11T14:51:54 Rename diff objects and split patch.h This makes no functional change to diff but renames a couple of the objects and splits the new git_patch (formerly git_diff_patch) into a new header file.
Russell Belfer 5c8f37a3 2013-05-17T17:33:03 Extend diff example Add --raw output format and (some) options to invoke rename/copy detection on the diff.
Russell Belfer 8d784001 2013-05-16T10:43:10 Make examples/diff.c compile vs threadsafe library
Ben Straub 20156653 2013-04-15T13:29:40 Clean up minor details
Ben Straub 299a224b 2013-04-15T12:00:04 Change git_revparse to output git_object pointers This will probably prevent many lookup/free operations in calling code.
Ben Straub 1aa21fe3 2013-04-09T05:03:51 Deprecate git_revparse_single and _rangelike
Russell Belfer 7bd53bf3 2013-03-02T13:52:38 Simplify diff example using revparse When the examples/diff.c was written, there was not yet a revparse API. Now we can use it to make command line parsing way better with less code. Yay!
Sebastian Bauer 75a0a800 2013-01-23T07:47:40 Don't clear the opt instance in the diff example. The version field is overwritten otherwise. The opt instance is already initialized properly.
Russell Belfer 56c72b75 2012-12-17T11:00:53 Fix diff constructor name order confusion The diff constructor functions had some confusing names, where the "old" side of the diff was coming after the "new" side. This reverses the order in the function name to make it less confusing. Specifically... * git_diff_index_to_tree becomes git_diff_tree_to_index * git_diff_workdir_to_index becomes git_diff_index_to_workdir * git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

Ben Straub bac695b5 2012-11-18T22:20:26 Examples: fix reference names
Russell Belfer 793c4385 2012-11-20T16:36:06 Update diff callback param order This makes the diff functions that take callbacks both take the payload parameter after the callback function pointers and pass the payload as the last argument to the callback function instead of the first. This should make them consistent with other callbacks across the API.
Russell Belfer bbe6dbec 2012-11-14T23:29:48 Add explicit git_index ptr to diff and checkout A number of diff APIs and the `git_checkout_index` API take a `git_repository` object an operate on the index. This updates them to take a `git_index` pointer explicitly and only fall back on the `git_repository` index if the index input is NULL. This makes it easier to operate on a temporary index.
Russell Belfer b90500f0 2012-11-01T14:08:30 Improve docs, examples, warnings This improves docs in some of the public header files, cleans up and improves some of the example code, and fixes a couple of pedantic warnings in places.
Russell Belfer 145e696b 2012-06-08T11:56:24 Minor fixes, cleanups, and clarifications There are three actual changes in this commit: 1. When the trailing newline of a file is removed in a diff, the change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed to the callback. Previously, the `ADD_EOFNL` constant was given which was just an error in my understanding of when the various circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and should never be generated. A new newline is simply an `ADD`. 2. Rewrote the `diff_delta__merge_like_cgit` function that contains the core logic of the `git_diff_merge` implementation. The new version doesn't actually have significantly different behavior, but the logic should be much more obvious, I think. 3. Fixed a bug in `git_diff_merge` where it freed a string pool while some of the string data was still in use. This led to `git_diff_print_patch` accessing memory that had been freed. The rest of this commit contains improved documentation in `diff.h` to make the behavior and the equivalencies with core git clearer, and a bunch of new tests to cover the various cases, oh and a minor simplification of `examples/diff.c`.

schu 288c8a25 2012-03-13T16:48:07 examples/diff: update example code Signed-off-by: schu <schu-github@schulog.org>
Russell Belfer a2e895be 2012-02-07T12:14:28 Continue implementation of git-diff * Implemented git_diff_index_to_tree * Reworked git_diff_options structure to handle more options * Made most of the options in git_diff_options actually work * Reorganized code a bit to remove some redundancy * Added option parsing to examples/diff.c to test most options
Russell Belfer 74fa4bfa 2012-02-28T16:14:47 Update diff to use iterators This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.
Russell Belfer 3a437590 2012-02-03T16:53:01 Clean up diff implementation for review This fixes several bugs, updates tests and docs, eliminates the FILE* assumption in favor of printing callbacks for the diff patch formatter helpers, and adds a "diff" example function that can perform a diff from the command line.
