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.
Moved documentation to Markdown.
Migrated the code to GitHub as code.google.com is turning down.
Fixed issue #10. Usage of expr under FreeBSD 7.2 (FreeNAS 0.7.1) and FreeBSD 8.0 that was causing many unit tests to fail.
Fixed issue where booleans were sometimes mis-configured to require additional values like other flags.
Changed _flags_fatal() to exit with FLAGS_ERROR immediately.
Fixed issue #11. When help is requested, the help flag is no longer prefixed with ‘[no]’.
Upgraded shUnit2 to 2.1.6.
Fixed issue #12. Requesting help shouldn't be considered an error.
Added the ability to override the use of the OS default getopt command by defining the FLAGS_GETOPT_CMD variable.
Updated gen_test_results.sh and versions from shUnit2 source.
Fixed issues# 13, 14. Added support for dashes (‘-’) in long flag names. The defined flag will still be declared with underscores (‘_’) due to shell limitations, so only one of a dashed flag name or an underscored flag name are allowed, not both.
Issue #20. Updated LGPL v2.1 license from http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt.
Issue #15. Use gexpr instead of expr on BSD variants.
Minor tweaks to make run on FreeBSD 9.1.
Fixed issue in shflags_test_public.sh where screens >80 columns were causing a test to fail.
Issue #22. Fixed broken testGetFlagInfo() test.
Created alternate validFloat() and validInt() functions that use shell built-ins where possible to increase performance and reduce the usage of the expr command.
Added separate built-in and expr functions for doing math.
MAJOR CHANGE! FLAGS_ARGC is now obsolete, and is replaced by FLAGS_ARGV. See below for more info.
Fixed issue# 7 where long flags defined with ‘=’ (e.g. --abc=123) made it impossible for the user to know how many non-flag command-line arguments were available because the value returned by FLAGS_ARGC was wrong. The FLAGS_ARGC value is now obsolete, but will be maintained for backwards compatibility. The new method of getting the non-flag arguments is by executing eval set -- "${FLAGS_ARGV}" after the FLAGS call. The arguments will then be available using the standard shell $#, $@, $*, $1, etc. variables.
Due to above fix for issue# 7, there is now proper support for mixing flags with non-flag arguments on the command-line. Previously, all non-flag arguments had to be at the end of the command-line.
Renamed _flags_standardGetopt() and _flags_enhancedGetopt() functions to _flags_getoptStandard() and _flags_getoptEnhanced().
Took out the setting and restoration of the ‘-u’ shell flag to treat unset variables as an error. No point in having it in this library as it is verified in the unit tests, and provides basically no benefit.
Fixed bug under Solaris where the generated help was adding extra ‘x’ characters.
Added checks for reserved flag variables (e.g. FLAGS_TRUE).
Fixed some unset variable bugs.
Now report the actual getopt error if there is one.
All tests now properly enable skipping based on whether a standard or enhanced getopt is found.
Added the OS version to OS release for Solaris.
Fixed flags_reset() so it unsets the default value environment vars.
FLAGS_PARENT no longer transforms into a constant so that it can be defined at run time in scripts.
Added warning about short flags being unsupported when there are problems parsing the options with getopt.
Add default values to end of description strings.
Fixed bug that returned an error instead of success when recalling the default values for empty strings.
Added warning when a duplicate flag definition is attempted.
Improved assert[Warn|Error]Msg() test helper grepping.
Replaced shell_versions.sh with a new versions library and created gen_test_results.sh to make releases easier.
Copied the coding standards from shUnit2, but haven't fully implemented them in shFlags yet.
Issue# 1: When a user defines their own --help flag, no more warning is thrown when FLAGS() is called stating that the help flag already defined.
Issue# 2: Passing the --nohelp option no longer gives help output.
Issue# 3: Added support for screen width detection.
Fixed bug where the help output added ‘[no]’ to all flag names
Added additional example files that are referenced by the documentation.
Improved zsh version and option checking.
Upgraded shUnit2 to 2.1.4
Added unit testing for the help output.
When including a library (e.g. shflags) in a script, zsh 3.0.8 doesn't actually execute the code in-line, but later. As such, variables that are defined in the library cannot be used until functions are called from the main code. This required the ‘help’ flag definition to be moved inside the FLAGS command.
This is the first official release, so everything is new.
