Version 1.1: Feedback

This release incorporates feedback from the release announcement. The examples are slowly being expanded, some corner cases improved, and some new functionality for tricky parsing situations.

• Added simple support for enumerations, allow non-printable objects #12
• Added app.parse_order() with original parse order (#13, #16)
• Added prefix_command(), which is like allow_extras but instantly stops and returns. (#8, #17)
• Removed Windows error (#10, #20)
• Some improvements to CMake, detect Python and no dependencies on Python 2 (like Python 3) (#18, #21)

Version 1.0: Official release

This is the first stable release for CLI11. Future releases will try to remain backward compatible and will follow semantic versioning if possible. There were a few small changes since version 0.9:

• Cleanup using clang-tidy and clang-format
• Small improvements to Timers, easier to subclass Error
• Move to 3-Clause BSD license

Version 0.9: Polish

This release focused on cleaning up the most exotic compiler warnings, fixing a few oddities of the config parser, and added a more natural method to check subcommands.

• Better CMake named target (CLI11)
• More warnings added, fixed
• Ini output now includes =false when default_also is true
• Ini no longer lists the help pointer
• Added test for inclusion in multiple files and linking, fixed issues (rarely needed for CLI, but nice for tools)
• Support for complex numbers
• Subcommands now test true/false directly or with ->parsed(), cleaner parse

Version 0.8: CLIUtils

This release moved the repository to the CLIUtils master organization.

• Moved to CLIUtils on GitHub
• Fixed docs build and a few links

Version 0.7: Code coverage 100%

Lots of small bugs fixed when adding code coverage, better in edge cases. Much more powerful ini support.

• Allow comments in ini files (lines starting with ;)
• Ini files support flags, vectors, subcommands
• Added CodeCov code coverage reports
• Lots of small bugfixes related to adding tests to increase coverage to 100%
• Error handling now uses scoped enum in errors
• Reparsing rules changed a little to accommodate Ini files. Callbacks are now called when parsing INI, and reset any time results are added.
• Adding extra utilities in full version only, Timer (not needed for parsing, but useful for general CLI applications).
• Better support for custom add_options like functions.

Version 0.6: Cleanup

Lots of cleanup and docs additions made it into this release. Parsing is simpler and more robust; fall through option added and works as expected; much more consistent variable names internally.

• Simplified parsing to use vector<string> only
• Fixed fallthrough, made it optional as well (default: off): .fallthrough().
• Added string versions of ->requires() and ->excludes() for consistency.
• Renamed protected members for internal consistency, grouped docs.
• Added the ability to add a number to .require_subcommand().

Version 0.5: Windows support

• Allow Hidden options.
• Throw OptionAlreadyAdded errors for matching subcommands or options, with ignore-case included, tests
• ->ignore_case() added to subcommands, options, and add_set_ignore_case. Subcommands inherit setting from parent App on creation.
• Subcommands now can be "chained", that is, left over arguments can now include subcommands that then get parsed. Subcommands are now a list (get_subcommands). Added got_subcommand(App_or_name) to check for subcommands.
• Added .allow_extras() to disable error on failure. Parse returns a vector of leftover options. Renamed error to ExtrasError, and now triggers on extra options too.
• Added require_subcommand to App, to simplify forcing subcommands. Do not do add_subcommand()->require_subcommand, since that is the subcommand, not the master App.
• Added printout of ini file text given parsed options, skips flags.
• Support for quotes and spaces in ini files
• Fixes to allow support for Windows (added Appveyor) (Uses -, not / syntax)

Version 0.4: Ini support

• Updates to help print
• Removed run, please use parse unless you subclass and add it
• Supports ini files mixed with command line, tested
• Added Range for further Plumbum compatibility
• Added function to print out ini file

Version 0.3: Plumbum compatibility

• Added ->requires, ->excludes, and ->envname from [Plumbum](http://plumbum. readthedocs.io/en/latest/)
• Supports ->mandatory from Plubmum
• More tests for help strings, improvements in formatting
• Support type and set syntax in positionals help strings
• Added help groups, with ->group("name") syntax
• Added initial support for ini file reading with add_config option.
• Supports GCC 4.7 again
• Clang 3.5 now required for tests due to googlemock usage, 3.4 should still work otherwise
• Changes setup for an explicit help bool in constructor/add_subcommand

Version 0.2: Leaner and meaner

• Moved to simpler syntax, where Option pointers are returned and operated on
• Removed make_ style options
• Simplified Validators, now only requires ->check(function)
• Removed Combiners
• Fixed pointers to Options, stored in unique_ptr now
• Added Option_p and App_p, mostly for internal use
• Startup sequence, including help flag, can be modified by subclasses
