parse-options: Allow to hide options from the default usage.

2007-11-23T06:11:28Z

This is useful for backward-compatibility aliases, or very advanced command line switches introduced for internal git usages and have no real use for a user. parse-options still shows them if the user asks for --help-all. Signed-off-by: Pierre Habouzit Signed-off-by: Junio C Hamano

parse-options new features.

2007-11-12T00:54:15Z

options flags: ~~~~~~~~~~~~~ PARSE_OPT_NONEG allow the caller to disallow the negated option to exists. option types: ~~~~~~~~~~~~ OPTION_BIT: ORs (or NANDs) a mask. OPTION_SET_INT: force the value to be set to this integer. OPTION_SET_PTR: force the value to be set to this pointer. helper: ~~~~~~ HAS_MULTI_BITS (in git-compat-util.h) is a bit-hack to check if an unsigned integer has more than one bit set, useful to check if conflicting options have been used.

Add shortcuts for very often used options.

It helps with consistency of the help strings, for example. Signed-off-by: Pierre Habouzit Signed-off-by: Shawn O. Pearce

parse-options: make some arguments optional, add callbacks.

2007-10-30T04:03:30Z

* add the possibility to use callbacks to parse some options, this can help implementing new options kinds with great flexibility. struct option gains a callback pointer and a `defval' where callbacks user can put either integers or pointers. callbacks also can use the `value' pointer for anything, preferably to the pointer to the final storage for the value though. * add a `flag' member to struct option to make explicit that this option may have an optional argument. The semantics depends on the option type. For INTEGERS, it means that if the switch is not used in its --long-form= form, and that there is no token after it or that the token does not starts with a digit, then it's assumed that the switch has no argument. For STRING or CALLBACK it works the same, except that the condition is that the next atom starts with a dash. This is needed to implement backward compatible behaviour with existing ways to parse the command line. Its use for new options is discouraged. Signed-off-by: Pierre Habouzit Signed-off-by: Shawn O.

parse-options: be able to generate usages automatically

Add a simple option parser.

2007-10-30T04:03:30Z

The option parser takes argc, argv, an array of struct option and a usage string. Each of the struct option elements in the array describes a valid option, its type and a pointer to the location where the value is written. The entry point is parse_options(), which scans through the given argv, and matches each option there against the list of valid options. During the scan, argv is rewritten to only contain the non-option command line arguments and the number of these is returned. Aggregation of single switches is allowed: -rC0 is the same as -r -C 0 (supposing that -C wants an arg). Every long option automatically support the option with the same name, prefixed with 'no-' to unset the switch. It assumes that initial value for strings are "NULL" and for integers is "0". Long options are supported either with '=' or without: --some-option=foo is the same as --some-option foo Acked-by: Kristian Høgsberg Signed-off-by: Pierre Habouzit Signed-off-by: Shawn O. Pearce
