Free unpack software for mac

The Unarchiver 2.0.1 is known as a convenient and effective compression tool. The Unarchiver is a much more capable replacement for "BOMArchiveHelper.app", the built-in archive unpacker program in Mac OS X. The Unarchiver is designed to handle many more formats than BOMArchiveHelper, and to better fit in with the design of the Finder.

It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. Personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, RAR, 7-zip, LhA, StuffIt and many other more and less obscure formats. The goal is to make The Unarchiver able to extract anything you give it. The Unarchiver uses the libxad unarchiving library to support many older, obscure formats.
If you have a compressed file that The Unarchiver does not open, please post a bug on the bug tracker, and include the file in question, and I will look into whether it is possible to add support for it!

Major Features:

1. Supports more formats than I can remember. Zip, Tar, Gzip, Bzip2, 7-Zip, Rar, LhA, StuffIt, several old Amiga file and disk archives, CAB, LZX, stuff I don't even know what it is.
2. Copies the Finder file-copying/moving/deleting interface for its interface.
3. Uses the character set autodetection code from Mozilla to auto-detect the encoding of the filenames in the archives.
4. Supports split archives for certain formats, like RAR.
5. Built around libxad. This is an old Amiga library for handling unpacking of archives. It supports a whole lot of formats, and added a couple more, and bugfixed old code. Also wrote a higher-level Objective-C wrapper around it, which might be useful for other projects too (including Xee).

• Should now handle concaternated bzip2 files.
• Fixes to the Japanese translation.
• Fixes to the LZMA parser.

rb-appscript 0.5 gives a tool to monitor scriptable Mac OS X applications applying ordinary Ruby scripts. Appscript makes Ruby a serious alternative to Apples own AppleScript language for automating your Mac.

Simple all-in-one binary installers are provided for Apple-installed Ruby 1.8 on Mac OS 10.4.x, and source files are included for installing appscript on other OS/Ruby versions. Example scripts, documentation and tutorial are also included.

Enhancements:

• OSAX module no longer errors on import in 10.5 if a ScriptingAdditions folder (e.g. ~/Library/ScriptingAdditions) doesn't exist
• added Appscript: Application#is_running method
• added hfs_path, #hfs_path methods to MacTypes: Alias, MacTypes:FileURL; existing path, #path methods now use CFURL functions to convert between POSIX paths and URLs
• aem/appscript now raises Connect: CantLaunchApplicationError instead of AE:MacOSError if unable to launch an application. Users should update existing code as necessary.
• fixed extconf.rb so that universal binaries build correctly
• built-in help system now uses ASDictionary 0.9.0+ instead of AppscriptHelpAgent. (AppscriptHelpAgent is no longer used as-of rb-appscript 0.5.0 and may be removed if previously installed.)
• #help method now writes messages to stderr instead of stdout
• Appscript: Reference#respond_to? now has identical signature to Object#respond_to? (optional second argument was previously missing)
• fixed bug in AE.convert_long_date_time_to_unix_seconds (used to unpack AEDescs of typeLongDateTime) where it would crash if passed a FixNum instead of a BigNum
• now allow methods that have been added to Object class at runtime (e.g. importing the pp module adds #pretty_print and #pretty_inspect) to be invoked on Appscript:Reference and Appscript:Application instances, assuming that the reference object doesnt already have a property/element/command by the same name. In other words, instances of these classes now behave more or less the same as instances of ordinary subclasses that use bound methods rather than #method_missing to handle incoming messages. Previously, calling (e.g.) #pretty_inspect on an appscript reference would result in a property/element/command not found error.
• improved behaviour of Appscript:Application#AS_new_reference when argument is nil (now returns a new reference to the root application object)
• OSAX:Application initialiser now optionally accepts static terminology glue module as its second argument. This is partly to provide scripts that need to run in 64-bit processes with a workaround for accessing the OSAX module, which cant yet automatically obtain osax terminology under 64-bit (see TODO file).
• added process_exists_for_path?, process_exists_for_pid?, process_exists_for_url?, process_exists_for_desc? class methods to AEM: Application
• deprecated AEM:Application.is_running? (will be removed in 1.0.0); any existing code that uses this method should be updated to use AEM: Application.process_exists_for_path? instead
• fixed minor formatting flaw in generic references #to_s method
• AEM:Application is now a subclass of AEMReference: Base, allowing aem Codecs instances to pack it
• added AB_export_vcard.rb sample script

Requirements:

• Mac OS X 10.3 or later
• Ruby 1.8 or later.
