2025-06-09fix help message for Func and BoolFunc flags #430Georges Varouchas
* have '.Type()' for boolfuncValue return "boolfunc" (dedicated value, which now makes it distinct from funcValue) * hide extra "(default )" by stating that "" should be treated as a zero value for a boolFlag note: - a boolfuncValue matches 'case boolFlag:', as it implements the boolFlag interface, - treating "" as a value which shouldn't trigger a "(default )" for a regular Bool flag does not look like a breaking change * hide extra "[=something]" for boolfuncValue * set default placeholder name for "boolfunc" and "func" flag types

2020-05-04Add exported functions to preserve `pkg/flag` compatibility (#220)Ryan McKern
* Rename out() to Output() This brings behavior inline with go's flag library, and allows for printing output directly to whatever the current FlagSet is using for output. This change will make it easier to correctly emit output to stdout or stderr (e.g. a user has requested a help screen, which should emit to stdout since it's the desired outcome). * improve compat. with pkg/flag by adding Name() pkg/flag has a public `Name()` function, which returns the name of the flag set when called. This commit adds that function, as well as a test for it. * Streamline testing Name() Testing `Name()` will move into its own explicit test, instead of running inline during `TestAddFlagSet()`.
