|
|
|
|
## Preface
|
|
|
|
This document covers any known issues and workarounds for the stated release of
|
|
shFlags.
|
|
|
|
|
|
## Release info
|
|
|
|
This is a minor bug fix release.
|
|
|
|
Please see the `CHANGES-1.2.md` file for a complete list of changes.
|
|
|
|
### Notable changes
|
|
|
|
Support for the BusyBox `ash` shell was added.
|
|
|
|
### Notable bug fixes
|
|
|
|
Fixed issue #28. 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.

|
## 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. See `src/shflags_test_helpers` to
|
|
see how the unit tests do this.
