Disruptive Changes:

• Slice flags no longer automatically parse slice values with commas into multiple values. To specify multiple values, use the flag multiple times. For example, this will produce one value: ./app -f one,two,three and ./ -f one -f two -f three will produce three values in the slice. #90

New Features:

• Adds built-in bash and zsh completion generators. Use completion zsh or completion bash on your app. This is on my default. To disable, use flaggy.DisableCompletion(). #1
• Flags can now be sorted alphabetically or reverse alphabetically using SortFlagsByLongName() and SortFlagsByLongNameReversed() #69
• Added a Github Action for test validation
• Added support for all types in the go standard library!

Fixes

• Fixed #84 - Unknown arguments supplied when the flag and subcommand have the same value name

Full Changelog: v1.5.2...v1.6.0

If you would like to use a variable number of arguments at the end of your program without the user specifying -- before the list, you can do this by setting flaggy.ShowHelpOnUnexpectedDisable() and then parsing the []string at flaggy.TrailingArguments. For more details, see Issue #79

• new trailingArguments example
• new tests for trailing arguments with positionals. fixed trailing arguments being incorrectly considered as positionals
