2010-12-07parse-options: make resuming easier after PARSE_OPT_STOP_AT_NON_OPTIONJonathan Nieder
Introduce a PARSE_OPT_NON_OPTION state, so parse_option_step() callers can easily distinguish between non-options and other reasons for option parsing termination (like "--"). Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-12-07parse-options: allow git commands to invent new option typesJonathan Nieder
parse-options provides a variety of option behaviors, including OPTION_CALLBACK, which should take care of just about any sane behavior. All supported behaviors obey the following constraint: A --foo option can only accept (and base its behavior on) one argument, which would be the following command-line argument in the "unsticked" form. Alas, some existing git commands have options that do not obey that constraint. For example, update-index --cacheinfo takes three arguments, and update-index --resolve takes all later parameters as arguments. Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so such option types can be supported without tempting inventors of other commands through mention in the public API. Commands can set the callback field to a function accepting three arguments: the option parsing context, the option itself, and a flag indicating whether the the option was negated. When the option is encountered, that function is called to take over from get_value(). The return value should be zero for success, -1 for usage errors. Thanks to Stephen Boyd for API guidance.

2010-12-07parse-options: never suppress arghelp if LITERAL_ARGHELP is setJonathan Nieder
The PARSE_OPT_LITERAL_ARGHELP flag allows a program to override the standard "<argument> for mandatory, [argument] for optional" markup in its help message. Extend it to override the usual "no text for disallowed", too (for the PARSE_OPT_NOARG | PARSE_OPT_LITERAL_ARGHELP case, which was previously meaningless), to be more intuitive. The motivation is to allow update-index to correctly advertise --cacheinfo <mode> <object> <path> add the specified entry to the index while abusing PARSE_OPT_NOARG to disallow the "sticked form" --cacheinfo=<mode> <object> <path> Noticed-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-12-07parse-options: do not infer PARSE_OPT_NOARG from option typeStephen Boyd
Simplify the "takes no value" error path by relying on PARSE_OPT_NOARG being set correctly. That is: - if the PARSE_OPT_NOARG flag is set, reject --opt=value regardless of the option type; - if the PARSE_OPT_NOARG flag is unset, accept --opt=value regardless of the option type. This way, the accepted usage more closely matches the usage advertised with --help-all. No functional change intended, since the NOARG flag is only used with "boolean-only" option types in existing parse_options callers.

2010-12-07parse-options: sanity check PARSE_OPT_NOARG flagJonathan Nieder
Some option types cannot use an argument --- boolean options that would set a bit or flag or increment a counter, for example. If configured in the flag word to accept an argument anyway, the result is an argument that is advertised in "program -h" output only to be rejected by parse-options::get_value. Luckily all current users of these option types use PARSE_OPT_NOARG and do not use PARSE_OPT_OPTARG. Add a check to ensure that that remains true. The check is run once for each invocation of parse_option_start().

2010-12-07parse-options: move NODASH sanity checks to parse_options_checkJonathan Nieder
A dashless switch (like '(' passed to 'git grep') cannot be negated, cannot be attached to an argument, and cannot have a long form. Currently parse-options runs the related sanity checks when the dashless option is used; better to always check them at the start of option parsing, so mistakes can be caught more quickly. The error message at the new call site is less specific about the nature of the error, for simplicity. On the other hand, it prints which switch was problematic. Before: fatal: BUG: dashless options can't be long After: error: BUG: switch '(' uses feature not supported for dashless options Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-12-07parse-options: clearer reporting of API misuseJonathan Nieder
The PARSE_OPT_LASTARG_DEFAULT flag is meant for options like --contains that (1) traditionally had a mandatory argument and (2) have some better behavior to use when appearing in the final position. It makes no sense to combine this with OPTARG, so ever since v1.6.4-rc0~71 (parse-options: add parse_options_check to validate option specs, 2009-07-09) this mistake is flagged with error: `--option` uses incompatible flags LASTARG_DEFAULT and OPTARG and an exit status representing an error in commandline usage. Unfortunately that which might confuse scripters calling such an erroneous program into thinking the _script_ contains an error. Clarify that it is an internal error by dying with a message beginning "error: BUG: ..." and status 128. While at it, clean up parse_options_check to prepare for more checks. Long term, it would be nicer to make such checks happen at compile time. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-12-07parse-options: Don't call parse_options_check() so muchStephen Boyd
parse_options_check() is being called for each invocation of parse_options_step which can be quite a bit for some commands. The commit introducing this function cb9d398 (parse-options: add parse_options_check to validate option specs., 2009-06-09) had the correct motivation and explicitly states that parse_options_check() should be called from parse_options_start().

2010-02-19Add an optional argument for --color optionsMark Lodato
Make git-branch, git-show-branch, git-grep, and all the diff-based programs accept an optional argument <when> for --color. The argument is a colorbool: "always", "never", or "auto". If no argument is given, "always" is used; --no-color is an alias for --color=never. This makes the command-line interface consistent with other GNU tools, such as `ls' and `grep', and with the git-config color options. Note that, without an argument, --color and --no-color work exactly as before. To implement this, two internal changes were made: 1. Allow the first argument of git_config_colorbool() to be NULL, in which case it returns -1 if the argument isn't "always", "never", or "auto". 2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb() to the option parsing library. The callback uses git_config_colorbool(), so color.h is now a dependency of parse-options.c.

2009-09-29parse-opt: ignore negation of OPT_NONEG for ambiguity checksAndreas Schwab
parse_long_opt always matches both --opt and --no-opt for any option "opt", and only get_value checks whether --no-opt is actually valid. Since the options for git branch contains both "no-merged" and "merged" there are two matches for --no-merge, but no exact match.

2009-06-21Fix various sparse warnings in the git source codeLinus Torvalds
There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

2009-05-25parse-opts: add OPT_FILENAME and transition builtinsStephen Boyd
Commit dbd0f5c (Files given on the command line are relative to $cwd, 2008-08-06) introduced parse_options_fix_filename() as a minimal fix. OPT_FILENAME is intended to be a more robust fix for the same issue. OPT_FILENAME and its associated enum OPTION_FILENAME are used to represent filename options within the parse options API. This option is similar to OPTION_STRING. If --no is prefixed to the option the filename is unset. If no argument is given and the default value is set, the filename is set to the default value. The difference is that the filename is prefixed with the prefix passed to parse_options() (or parse_options_start()). Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use OPT_FILENAME with their filename options. Also, rename parse_options_fix_filename() to fix_filename() as it is no longer extern.

Usually, the argh element in struct option points at a placeholder value (e.g. "val"), and is shown in the usage message as --option=<val> by enclosing the string inside of angle brackets. When the option is more complex (e.g. optional arguments separated by a comma), you would want to produce a usage message that looks like --option=<val1>[,<val2>] In such a case, the caller can pass a string to argh with placeholders already enclosed in necessary angle brackets (e.g. "<val1>[,<val2>]") and set this flag.

2008-08-06Files given on the command line are relative to $cwdJunio C Hamano
When running "git commit -F file" and "git tag -F file" from a subdirectory, we should take it as relative to the directory we started from, not relative to the top-level directory. This adds a helper function "parse_options_fix_filename()" to make it more convenient to fix this class of issues. Ideally, parse_options() should support a new type of option, "OPT_FILENAME", to do this uniformly, but this patch is meant to go to 'maint' to fix it minimally. One thing to note is that value for "commit template file" that comes from the command line is taken as relative to $cwd just like other parameters, but when it comes from the configuration varilable 'commit.template', it is taken as relative to the working tree root as before. I think this difference actually is sensible (not that I particularly think commit.template itself is sensible). Signed-off-by: Junio C Hamano <gitster@pobox.com>
