Changelog

This is the changelog for cxxopts, a C++11 library for parsing command line options. The project adheres to semantic versioning.

3.0

Changed

• Only search for a C++ compiler in CMakeLists.txt.
• Allow for exceptions to be disabled.
• Fix duplicate default options when there is a short and long option.
• Add CXXOPTS_NO_EXCEPTIONS to disable exceptions.
• Fix char parsing for space and check for length.
• Change argument type in Options::parse from char** to const char**.
• Refactor parser to not change its arguments.
• ParseResult doesn't depend on a reference to the parser.

Added

• A list of unmatched arguments is available in ParseResult.

2.2

Changed

• Allow integers to have leading zeroes.
• Build the tests by default.
• Don't check for container when showing positional help.

Added

• Iterator inputs to parse_positional.
• Throw an exception if the option in parse_positional doesn't exist.
• Parse a delimited list in a single argument for vector options.
• Add an option to disable implicit value on booleans.

Bug Fixes

• Fix a warning about possible loss of data.
• Fix version numbering in CMakeLists.txt
• Remove unused declaration of the undefined ParseResult::get_option.
• Throw on invalid option syntax when beginning with a -.
• Throw in as when option wasn't present.
• Fix catching exceptions by reference.
• Fix out of bounds errors parsing integers.

2.1.1

Bug Fixes

• Revert the change adding const type for argv, because most users expect to pass a non-const argv from main.

2.1

Changed

• Options with implicit arguments now require the --option=value form if they are to be specified with an option. This is to remove the ambiguity when a positional argument could follow an option with an implicit value. For example, --foo value, where foo has an implicit value, will be parsed as --foo=implicit and a positional argument value.
• Boolean values are no longer special, but are just an option with a default and implicit value.

Added

• Added support for std::optional as a storage type.
• Allow the help string to be customised.
• Use const for the type in the argv parameter, since the contents of the arguments is never modified.

Bug Fixes

• Building against GCC 4.9 was broken due to overly strict shadow warnings.
• Fixed an ambiguous overload in the parse_positional function when an initializer_list was directly passed.
• Fixed precedence in the Boolean value regex.

2.0

Changed

• Options::parse returns a ParseResult rather than storing the parse result internally.
• Options with default values now get counted as appearing once if they were not specified by the user.

Added

• A new ParseResult object that is the immutable result of parsing. It responds to the same count and operator[] as Options of 1.x did.
• The function ParseResult::arguments returns a vector of the parsed arguments to iterate through in the order they were provided.
• The symbol cxxopts::version for the version of the library.
• Booleans can be specified with various strings and explicitly set false.

1.x

The 1.x series was the first major version of the library, with release numbers starting to follow semantic versioning, after 0.x being unstable. It never had a changelog maintained for it. Releases mostly contained bug fixes, with the occasional feature added.
