Fix bool flag hangling if default is `true`
opened by zen3ger 4If a boolean flag's default value was true it was not possible to toggle it as a set flag's value was hardcoded to true. This is fixed by using the negated default value in case the flag is set.
-
Add remaining C numeric types; make default values optional; add ability to mark flags as required
opened by dyeo 1Breaks existing API?: Yes (the
flag_bool,flag_str, etc. functions have a parameter removed)flag_[TYPE]_defaultfunctions added to allow the user to specify a default value on a flag, by providing its pointer handle. Similar functionality forflag_required.On C11-compatible machines or higher, the
flag_defaultmacro is available (supplied via._Generic), which removes the need to supply a type when setting a default value on a flag.
