2019-11-07parse-options.h: add new options `--pathspec-from-file`, `--pathspec-file-nul`Libravatar Alexandr Miloslavskiy1-0/+2
Support for various porcelain commands will arrive via additional patches. `--pathspec-from-file` solves the problem of commandline length limit for UIs built on top of git. Plumbing commands are not always a good fit, for two major reasons: 1) Some UIs show executed commands to user. In this case, porcelain commands are expected. One reason for that is letting user learn git commands by clicking UI buttons. The other reason is letting user study the history of commands in case of any unexpected results. Both of these will lose most of their value if UI uses combinations of arcane plumbing commands. 2) Some UIs have started and grown with porcelain commands. Replacing existing logic with plumbing commands could be cumbersome and prone to various new problems. `--pathspec-from-file` will behave very close to pathspec passed in commandline args, so that switching from one to another is simple. `--pathspec-from-file` will read either a specified file or `stdin` (when file is exactly "-"). Reading from file is a good way to avoid competing for `stdin`, and also gives some extra flexibility. `--pathspec-file-nul` switch mirrors `-z` already used in various places. Some porcelain commands, such as `git commit`, already use `-z`, therefore it needed a new unambiguous name. New options do not have shorthands to avoid shorthand conflicts. It is not expected that they will be typed in console. Signed-off-by: Alexandr Miloslavskiy <alexandr.miloslavskiy@syntevo.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In f41179f16ba2 (parse-options: avoid magic return codes, 2019-01-27), the signature of the low-level parse-opt callback function was changed to return an `enum`. And while the implementations were changed, one declaration was left unchanged, still claiming to return `int`. This can potentially lead to problems, as compilers are free to choose any integral type for an `enum` as long as it can represent all declared values.

2019-05-07parse-options: don't emit "ambiguous option" for aliasesLibravatar Nguyễn Thái Ngọc Duy1-0/+6
Change the option parsing machinery so that e.g. "clone --recurs ..." doesn't error out because "clone" understands both "--recursive" and "--recurse-submodules" to mean the same thing. Initially "clone" just understood --recursive until the --recurses-submodules alias was added in ccdd3da652 ("clone: Add the --recurse-submodules option as alias for --recursive", 2010-11-04). Since bb62e0a99f ("clone: teach --recurse-submodules to optionally take a pathspec", 2017-03-17) the longer form has been promoted to the default. But due to the way the options parsing machinery works this resulted in the rather absurd situation of: $ git clone --recurs [...] error: ambiguous option: recurs (could be --recursive or --recurse-submodules) Add OPT_ALIAS() to express this link between two or more options and use it in git-clone. Multiple aliases of an option could be written as OPT_ALIAS(0, "alias1", "original-name"), OPT_ALIAS(0, "alias2", "original-name"), ... The current implementation is not exactly optimal in this case. But we can optimize it when it becomes a problem. So far we don't even have two aliases of any option. A big chunk of code is actually from Junio C Hamano.

2019-03-18parse-options: make OPT_ARGUMENT() more usefulLibravatar Johannes Schindelin1-2/+2
`OPT_ARGUMENT()` is intended to keep the specified long option in `argv` and not to do anything else. However, it would make a lot of sense for the caller to know whether this option was seen at all or not. For example, we want to teach `git difftool` to work outside of any Git worktree, but only when `--no-index` was specified. Note: nothing in Git uses OPT_ARGUMENT(). Even worse, looking through the commit history, one can easily see that nothing even ever used it, apart from the regression test. So not only do we make `OPT_ARGUMENT()` more useful, we are also about to introduce its first real user!

2019-03-08commit-tree: utilize parse-options apiLibravatar Brandon Richardson1-0/+11
Rather than parse options manually, which is both difficult to read and error prone, parse options supplied to commit-tree using the parse-options api. It was discovered that the --no-gpg-sign option was documented but not implemented in commit 70ddbd7767 (commit-tree: add missing --gpg-sign flag, 2019-01-19), and the existing implementation would attempt to translate the option as a tree oid. It was also suggested earlier in commit 55ca3f99ae (commit-tree: add and document --no-gpg-sign, 2013-12-13) that commit-tree should be migrated to utilize the parse-options api, which could help prevent mistakes like this in the future. Hence this change. Also update the documentation to better describe that mixing `-m` and `-F` options will correctly compose commit log messages in the order in which the options are given. In the process, mark various strings for translation. Signed-off-by: Brandon Richardson <brandon1024.br@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

OPTION_CALLBACK is much simpler/safer to use, but parse_opt_cb does not allow access to parse_opt_ctx_t, which sometimes is useful (e.g. to obtain the prefix). Extending parse_opt_cb to take parse_opt_cb could result in a lot of changes. Instead let's just allow ll_callback to be used with OPTION_CALLBACK. The user will have to be careful, not to change anything in ctx, or return wrong result code. But that's the price for ll_callback.

2019-01-27parse-options: add one-shot modeLibravatar Nguyễn Thái Ngọc Duy1-4/+13
This is to help reimplement diff_opt_parse() using parse_options().

It's to help converting diff/rev option parsing. Once that work is over and we can just use parse_options() throughout the code base, this will be deleted.

2018-11-12parse-options: replace opterror() with optname()Libravatar Nguyễn Thái Ngọc Duy1-4/+1
Introduce optname() that does the early half of original opterror() to come up with the name of the option reported back to the user, and use it to kill opterror(). The callers of opterror() now directly call error() using the string returned by opterror() instead. There are a few issues with opterror() - it tries to assemble an English sentence from pieces. This is not great for translators because we give them pieces instead of a full sentence. - It's a wrapper around error() and needs some hack to let the compiler know it always returns -1. - Since it takes a string instead of printf format, one call site has to assemble the string manually before passing to it. Using error() directly solves the second and third problems. It kind helps the first problem as well because "%s does foo" does give a translator a full sentence in a sense and let them reorder if needed. But it has limitations, if the subject part has to change based on the rest of the sentence, that language is screwed. This is also why I try to avoid calling optname() when 'flags' is known in advance. Mark of these strings for translation as well while at there.

2018-11-06assert NOARG/NONEG behavior of parse-options callbacksLibravatar Jeff King1-0/+14
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

There are no users of OPT_DATE except for test-parse-options; its only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE() and use it, 2013-04-25). It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback does not respect the "unset" flag, and will feed NULL to approxidate() and segfault. Probably this should be marked with NONEG, or the callback should set the timestamp to some sentinel value (e.g,. "0", or "(time_t)-1"). But since there are no callers, deleting it means we don't even have to think about what the right behavior should be.

Given a hypothetically bad commit cf5c7253e0, the git version to revert to can be found with this hacky two-liner: (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') | sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10 With this new --no-contains option the same can be achieved with: git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10 As the filtering machinery is shared between the tag, branch & for-each-ref commands, implement this for those commands too. A practical use for this with "branch" is e.g. finding branches which were branched off between v2.8.0 and v2.10.0: git branch --contains v2.8.0 --no-contains v2.10.0 The "describe" command also has a --contains option, but its semantics are unrelated to what tag/branch/for-each-ref use --contains for. A --no-contains option for "describe" wouldn't make any sense, other than being exactly equivalent to not supplying --contains at all, which would be confusing at best. Add a --without option to "tag" as an alias for --no-contains, for consistency with --with and --contains. The --with option is undocumented, and possibly the only user of it is Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's trivial to support, so let's do that. The additions to the the test suite are inverse copies of the corresponding --contains tests. With this change --no-contains for tag, branch & for-each-ref is just as well tested as the existing --contains option. In addition to those tests, add a test for "tag" which asserts that --no-contains won't find tree/blob tags, which is slightly unintuitive, but consistent with how --contains works & is documented.

2017-03-24parse-options: add OPT_NONEG to the "contains" optionLibravatar Ævar Arnfjörð Bjarmason1-2/+2
Add the OPT_NONEG flag to the "contains" option and its hidden synonym "with". Since this was added in commit 694a577519 ("git-branch --contains=commit", 2007-11-07) giving --no-{contains,with} hasn't been an error, but has emitted the help output since filter.with_commit wouldn't get set. Now git will emit "error: unknown option `no-{contains,with}'" at the top of the help output.

2016-09-26Merge branch 'mh/diff-indent-heuristic'Libravatar Junio C Hamano1-0/+1
Output from "git diff" can be made easier to read by selecting which lines are common and which lines are added/deleted intelligently when the lines before and after the changed section are the same. A command line option is added to help with the experiment to find a good heuristics. * mh/diff-indent-heuristic: blame: honor the diff heuristic options and config parse-options: add parse_opt_unknown_cb() diff: improve positioning of add/delete blocks in diffs xdl_change_compact(): introduce the concept of a change group recs_match(): take two xrecord_t pointers as arguments is_blank_line(): take a single xrecord_t as argument xdl_change_compact(): only use heuristic if group can't be matched xdl_change_compact(): fix compaction heuristic to adjust ixo
2016-09-19parse-options: add parse_opt_unknown_cb()Libravatar Michael Haggerty1-0/+1
Add a new callback function, parse_opt_unknown_cb(), which returns -2 to indicate that the corresponding option is unknown. This can be used to add "-h" documentation for an option that will be handled externally to parse_options().
