DEFINE_boolean misbehaves when help-string is empty. + + +## General info + +### The unit tests + +shFlags is designed to work on as many environments as possible, but not all +environments are created equal. As such, not all of the unit tests will succeed +on every platform. The unit tests are therefore designed to fail, indicating to +the tester that the supported functionality is not present, but an additional +test is present to verify that shFlags properly caught the limitation and +presented the user with an appropriate error message. + +shFlags tries to support both the standard and enhanced versions of `getopt`. +As each responds differently, and not everything is supported on the standard +version, some unit tests will be skipped (i.e. ASSERTS will not be thrown) when +the standard version of `getopt` is detected. The reason being that there is +no point testing for functionality that is positively known not to exist. A +tally of skipped tests will be kept for later reference. + +### Standard vs Enhanced getopt + +Here is a matrix of the supported features of the various `getopt` variants. + +| Feature | std | enh | +|-----------------------------------------|-----|-----| +| short option names | Y | Y | +| long option names | N | Y | +| spaces in string options | N | Y | +| intermixing of flag and non-flag values | N | Y | + + +## Known Issues + +The `getopt` version provided by default with all versions of Mac OS X (up to +and including 10.10.2) and Solaris (up to and including Solaris 10 and +OpenSolaris) is the standard version. + +## Workarounds + +The Zsh shell requires the `shwordsplit` option to be set and the special +`FLAGS_PARENT` variable must be defined.
