are called so that the right ones are chosen.

Fix overflow error in integer_parser. (#417) 
Fixes #290.
Checking for overflow should be done before integer overflows.
There are two checks:
(result > limit / base) is used for limits greater than rounded up to base,
e.g. for 65535 it will activate for 65540 and higher.
(result * base > limit - digit) is used for limit+1 to limit+n below
next base rounded number, e.g. 65536 up to 65539.

Eyal Rozenberg e976f964c3
Fix issue #240: Multiple long option names / aliases (#349) 
* Fixes #240: Multiple long option names / aliases

* We now use a vector of long option names instead of a single name
* When specifying an option, you can provide multiple names separated by commas, at most one of which may have a length of 1 (not necessarily the first specified name). The length-1 name is the single-hyphen switch (the "short name").
* Hashing uses the first long name
* Option help currently only uses the first long name.

Fixes #345, fixes #346: Exception code tweaks (#347) 
* Fixes #345, fixes #346, regards #340: Put exceptions in a sub-namespace and renamed them accordingly.

* Also fixed some "loose ends" regarding namespace indentation which were missing in PR #350.

* Dropped `required_option_missing` as it is unused.

Fix passing a const array to parse (#258) 
Fixes #257. The input array is not modified, so we can declare this as
`char const* const*`.

Jarryd Beck fedf9d7b57 Refactor parser 
Major refactor of the parsing code organisation to improve encapsulation
and not modify the input arguments. The returned result no longer has
pointers into the original option specification.

Kjetil Andresen 15e8a74e95
Support 'const char**' arguments in Options::parse (#250) 
`cxxopts` doesn't modify the contents of the argv strings. This changes
the parse function to take a reference to a `const char**`.

Eyal Rozenberg 5f43f4cbfe
Fixes #245: Mention the option name when throwing on "no value" (#246) 
* Fixes #245:

* Added a new exception type: `option_has_no_value_exception`; throwing it when an option has no value we can cast with `as()`, instead of an `std::domain_error`.
* The `OptionValue` type now holds a pointer to the long option name (in its corresponding key within ParseResults's `m_results` field.

Jarryd Beck 5da5d67111 Throw exception on invalid positional argument 
Fixes #169. It seems reasonable to throw an exception when an attempt is
made to parse into positional parameters that don't exist.

Jean Guyomarc'h 51f9a94c91 Fix invalid exception type in catch (#149) 
g++ 8.2.0 refuses to compile the test suite because of polymorphic types
that are caught by value. They shall be caught by reference instead.

Jarryd Beck 76bd60dc17 Add support for std::optional 
Fixes #93. This adds C++17 only support for `std::optional` values for
command line parameters.
 2018-01-31 18:25:52 +11:00
Jarryd Beck e792760ab9 Changes default values so that they aren't counted 
Fixes #96. Default values of options not specified on the command line
had a `count` of 1. It would be better if they had a count of 0 because
they were not actually specified, so that count is only for options
given by the user.
