Unreleased

3.1.0 - 2023-07-24

Added

  • Implement either command (#130 - thanks @alezummo)

3.0.1 - 2020-04-20

  • Add a LICENSE.txt file to the released package
  • Test fixes (thanks @aried3r, @neontapir, @npras)

3.0.0 - 2018-08-24

  • The gem has been officially renamed to optimist

2.1.3 - 2018-07-05

  • Refactor each option type into subclasses of Option. Define a registry for the registration of each option. This makes the code more modular and facilitates extension by allowing additional Option subclasses. (thanks @clxy)
  • Fixed implementation of ignore_invalid_options. (thanks @metcalf)
  • Various warning cleanup for ruby 2.1, 2.3, etc. (thanks @nanobowers)
  • Optimist.die can now accept an error code.
  • fixed default (thanks @nanobowers)
  • Change from ruby license to MIT license in the code.

2.1.2 - 2015-03-10

  • loosen mime-types requirements (for better ruby 1.8.7 support)
  • use io/console gem instead of curses (for better jruby support)
  • fix parsing bug when chronic gem is not available
  • allow default array to be empty if a type is specified
  • better specified license and better spec coverage

2.1.1 - 2015-01-03

  • Remove curses as a hard dependency. It is optional. This can leverage the gem if it is present.
  • Fix ruby -w warnings

2.1.0 - 2015-01-02

  • Integer parser now supports underscore separator.
  • Add Parser#usage and Parser#synopsis commands for creating a standard banner message. Using Parser#banner directly will override both of those.
  • Add Parser#ignore_invalid_options to prevent erroring on unknown options.
  • Allow flags to act as switches if they have defaults set and no value is passed on the commandline
  • Parser#opt learned to accept a block or a :callback option which it will call after parsing the option.
  • Add Optimist::educate which displays the help message and dies.
  • Reformat help message to be more GNUish.
  • Fix command name in help message when script has no extension.
  • Fix handling of newlines inside descriptions
  • Documentation and other fixes.

2.0 - 2012-08-11

  • Change flag logic: --no-X will always be false, and --X will always be true, regardless of default.
  • For flags that default to true, display --no-X instead of --X in the help menu. Accept both versions on the commandline.
  • Fix a spurious warning
  • Update Rakefile to 1.9
  • Minor documentation fixes

1.16.2 - 2010-04-06

  • Bugfix in Optimist::options. Thanks to Brian C. Thomas for pointing it out.

1.16.1 - 2010-04-05

  • Bugfix in Optimist::die method introduced in last release.

1.16 - 2010-04-01

  • Add Optimist::with_standard_exception_handling method for easing the use of Parser directly.
  • Handle scientific notation in float arguments, thanks to Will Fitzgerald.
  • Drop hoe dependency.

1.15 - 2009-09-30

  • Don't raise an exception when out of short arguments (thanks to Rafael Sevilla for pointing out how dumb this behavior was).

1.14 - 2009-06-19

  • Make :multi arguments default to [], not nil, when not set on the commandline.
  • Minor commenting and error message improvements

1.13 - 2009-03-16

  • Fix parsing of "--longarg=".

1.12 - 2009-01-30

  • Fix some unit test failures in the last release. Should be more careful.
  • Make default short options only be assigned *after- all user-specified short options. Now there's a little less juggling to do when you just want to specify a few short options.

1.11 - 2009-01-29

  • Set _given keys in the results hash for options that were specified on the commandline.

1.10.2 - 2008-10-23

  • No longer try stty size for screen size detection. Just use curses, and screen users will have to deal with the screen clearing.

1.10.1 - 2008-10-22

  • Options hash now responds to method calls as well as standard hash lookup.
  • Default values for multi-occurrence parameters now autoboxed.
  • The relationship between multi-value, multi-occurrence, and default values improved and explained.
  • Documentation improvements.

1.10 - 2008-10-21

  • Added :io type for parameters that point to IO streams (filenames, URIs, etc).
  • For screen size detection, first try stty size before loading Curses.
  • Improved documentation.

1.9 - 2008-08-20

  • Added 'stop_on_unknown' command to stop parsing on any unknown argument. This is useful for handling sub-commands when you don't know the entire set of commands up front. (E.g. if the initial arguments can change it.)
  • Added a :multi option for parameters, signifying that they can be specified multiple times.
  • Added :ints, :strings, :doubles, and :floats option types, which can take multiple arguments.

1.8.2 - 2008-06-25

  • Bugfix for #conflicts and #depends error messages

1.8.1 - 2008-06-24

  • Bugfix for short option autocreation
  • More aggressive documentation

1.8 - 2008-06-16

  • Sub-command support via Parser#stop_on

1.7.2 - 2008-01-16

  • Ruby 1.9-ify. Apparently this means replacing :'s with ;'s.

1.7.1 - 2008-01-07

  • Documentation improvements

1.7 - 2007-06-17

  • Fix incorrect error message for multiple missing required arguments (thanks to Neill Zero)

1.6 - 2007-04-01

  • Don't attempt curses screen-width magic unless running on a terminal.

1.5 - 2007-03-31

  • --help and --version do the right thing even if the rest of the command line is incorrect.
  • Added #conflicts and #depends to model dependencies and exclusivity between arguments.
  • Minor bugfixes.

1.4 - 2007-03-26

  • Disable short options with :short => :none.
  • Minor bugfixes and error message improvements.

1.3 - 2007-01-31

  • Wrap at (screen width - 1) instead of screen width.
  • User can override --help and --version.
  • Bugfix in handling of -v and -h.
  • More tests to confirm the above.

1.2 - 2007-01-31

  • Minor documentation tweaks.
  • Removed hoe dependency.

1.1 - 2007-01-30

  • Optimist::options now passes any arguments as block arguments. Since instance variables are not properly captured by the block, this makes it slightly less noisy to pass them in as local variables. (A real-life use for _why's cloaker!)
  • Help display now preserves original argument order.
  • Optimist::die now also has a single string form in case death is not due to a single argument.
  • Parser#text now an alias for Parser#banner, and can be called multiple times, with the output being placed in the right position in the help text.
  • Slightly more indicative formatting for parameterized arguments.

1.0 - 2007-01-29

  • Initial release.
