• Implemented a fix for a rare condition wherein a positional value overlaps a subcommand with the same name.

This is a follow up v1.7.0 release after rapid re-release of v1.6.0 tag caused go module caching error. This release addresses nearly all known issues and proposed feature additions of Flaggy while retaining a no-dependency policy.

• Update module to Go 1.25
• Streamline argument delegation between parsers
• Clarify benchmark intent and document agent workflow
• Fixes #68 - Subcommands and globals are displayed in different help sections on subcommands
• Refactored help output logic
• Fixes #96 - Empty flag causes missing input error
• Added Fixes #74 improved alignment on help output
• Add benchmark tests
• New gopher logo on README.md
• Fixes #98 - add CONTRIBUTING.md

🎉 First release since May 2022 thanks to AI! 🎉

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!
  • []net.IPMask
  • time.Time
  • url.URL
  • net.IPNet
  • net.TCPAddr
  • net.UDPAddr

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
