Peter M. Groen / CLI11

CHANGELOG.md 14.3 KB

Version 1.5: Optionals

This version introduced support for optionals, along with clarification and examples of custom conversion overloads. Enums now have been dropped from the automatic conversion system, allowing explicit protection for out-of-range ints (or a completely custom conversion). This version has some internal cleanup and improved support for the newest compilers. Several bugs were fixed, as well.

Note: This is the final release with requires, please switch to needs.

  • Fix unlimited short options eating two values before checking for positionals when no space present #90
  • Symmetric exclude text when excluding options, exclude can be called multiple times #64
  • Support for std::optional, std::experimental::optional, and boost::optional added if __has_include is supported #95
  • All macros/CMake variables now start with CLI11_ instead of just CLI_ #95
  • The internal stream was not being cleared before use in some cases. Fixed. #95
  • Using an emum now requires explicit conversion overload #97
  • The separator -- now is removed when it ends unlimited arguments #100

Other, non-user facing changes:

  • Added Macros.hpp with better C++ mode discovery #95
  • Deprecated macros added for all platforms
  • C++17 is now tested on supported platforms #95
  • Informational printout now added to CTest #95
  • Better single file generation #95
  • Added support for GTest on MSVC 2017 (but not in C++17 mode, will need next version of GTest)
  • Types now have a specific size, separate from the expected number - cleaner and more powerful internally #92
  • Examples now run as part of testing #99

Version 1.4: More feedback

This version adds lots of smaller fixes and additions after the refactor in version 1.3. More ways to download and use CLI11 in CMake have been added. INI files have improved support.

  • Lexical cast is now more strict than before #68 and fails on overflow #84
  • Added get_parent() to access the parent from a subcommand
  • Added ExistingPath validator #73
  • app.allow_ini_extras() added to allow extras in INI files #70
  • Multiline INI comments now supported
  • Descriptions can now be written with config_to_str #66
  • Double printing of error message fixed #77
  • Renamed requires to needs to avoid C++20 keyword #75, #82
  • MakeSingleHeader now works if outside of git #78
  • Adding install support for CMake #79, improved support for find_package #83, #84
  • Added support for Conan.io #83

Version 1.3: Refactor

This version focused on refactoring several key systems to ensure correct behavior in the interaction of different settings. Most caveats about features only working on the main App have been addressed, and extra arguments have been reworked. Inheritance of defaults makes configuring CLI11 much easier without having to subclass. Policies add new ways to handle multiple arguments to match your favorite CLI programs. Error messages and help messages are better and more flexible. Several bugs and odd behaviors in the parser have been fixed.

  • Added a version macro, CLI11_VERSION, along with *_MAJOR, *_MINOR, and *_PATCH, for programmatic access to the version.
  • Reworked the way defaults are set and inherited; explicit control given to user with ->option_defaults() #48
  • Hidden options now are based on an empty group name, instead of special "hidden" keyword #48
  • parse no longer returns (so CLI11_PARSE is always usable) #37
  • Added remaining() and remaining_size() #37
  • allow_extras and prefix_command are now valid on subcommands #37
  • Added take_last to only take last value passed #40
  • Added multi_option_policy and shortcuts to provide more control than just a take last policy #59
  • More detailed error messages in a few cases #41
  • Footers can be added to help #42
  • Help flags are easier to customize #43
  • Subcommand now support groups #46
  • CLI::RuntimeError added, for easy exit with error codes #45
  • The clang-format script is now no longer "hidden" #48
  • The order is now preserved for subcommands (list and callbacks) #49
  • Tests now run individually, utilizing CMake 3.10 additions if possible #50
  • Failure messages are now customizable, with a shorter default #52
  • Some improvements to error codes #53
  • require_subcommand now offers a two-argument form and negative values on the one-argument form are more useful #51
  • Subcommands no longer match after the max required number is obtained #51
  • Unlimited options no longer prioritize over remaining/unlimited positionals #51
  • Added ->transform which modifies the string parsed #54
  • Changed of API in validators to void(std::string &) (const for users), throwing providing nicer errors #54
  • Added CLI::ArgumentMismatch #56 and fixed missing failure if one arg expected #55
  • Support for minimum unlimited expected arguments #56
  • Single internal arg parse function #56
  • Allow options to be disabled from INI file, rename add_config to set_config #60

Converting from CLI11 1.2:

  • app.parse no longer returns a vector. Instead, use app.remaining(true).
  • "hidden" is no longer a special group name, instead use ""
  • Validators API has changed to return an error string; use .empty() to get the old bool back
  • Use .set_help_flag instead of accessing the help pointer directly (discouraged, but not removed yet)
  • add_config has been renamed to set_config
  • Errors thrown in some cases are slightly more specific

Version 1.2: Stability

This release focuses on making CLI11 behave properly in corner cases, and with config files on the command line. This includes fixes for a variety of reported issues. A few features were added to make life easier, as well; such as a new flag callback and a macro for the parse command.

  • Added functional form of flag #33, automatic on C++14
  • Fixed Config file search if passed on command line #30
  • Added CLI11_PARSE(app, argc, argv) macro for simple parse commands (does not support returning arg)
  • The name string can now contain spaces around commas #29
  • set_default_str now only sets string, and set_default_val will evaluate the default string given #26
  • Required positionals now take priority over subcommands #23
  • Extra requirements enforced by Travis

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 warning (#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
  • 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

Version 0.1: First release

First release before major cleanup. Still has make syntax and combiners; very clever syntax but not the best or most commonly expected way to work.
