This document covers any known issues and workarounds for the stated release of shFlags.
This is a minor bug fix release.
Please see the CHANGES-1.2.md file for a complete list of changes.
Changed from the LGPL v2.1 license to the Apache v2.0 license so that others can include the library or make changes without needing to release the modified source code as well.
None
Issue #10 - Changed the internal usage of the expn command to fix issues under FreeBSD.
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.
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 |
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.
The Zsh shell requires the shwordsplit option to be set and the special FLAGS_PARENT variable must be defined. See src/shflags_test_helpers to see how the unit tests do this.
