ObjC wrapper around the 7zip/LZMA SDK

SevenZip

SevenZip is an Objective-C wrapper framework around p7zip (v16.02), which in turn is a Unix port of 7zip.

Requirements

To build: Xcode 8, Swift 3
To use: OSX 10.9, iOS 8.4

(It probably runs on earlier platform versions as well but I didn't care enough to check.)

Building

1. clone this repo

2. from the repo root, run

   $ scripts/setup.sh
   

3. open the Xcode project and build the SevenZip (OSX)/SevenZip (iOS) target

If you just want to toy with it, take a look at the SVZDemo/SVZDemo-iOS apps (separate targets).

Features

• listing the archive contents
• extracting all/some files from archives to file/memory
• creating new archives with files/directories
• adding/removing files to/from existing archives
• support for password-protected archives
• specifying compression level

Coming soon: tests, automated builds, documentation, free candy/beer. Until then, submit your requests/bug reports as issues.

Disclaimer

At the moment, the project is still in an early stage of development but you can already do all the usual stuff with 7z archives from code without having to get your hands dirty with the underlying MFC/COM+/OLE/godknowswhat implementation.

Be warned that the code is experimental, has few tests, and is provided as-is. Be prepared for unwanted/undefined behavior, data losses, nazgul attacks etc.

sevenzip's Issues

Support more codecs

currently only LZMA/2 are supported, but BCJ/2 is also common in archives

Set up Travis build

Doesn't handle other files than .7z

Thus far I tried .rar and .zip files and every time I try to open such an archive I get this error message:
Error Domain=SVZArchiveErrorDomain Code=-2 "(null)"

I did a little bit of debugging and found out, that no matter what kind of archive I try to open, the "Open" method in "7zHandler" is executed and I suppose e.g. for a .rar file the "Open" method in "RarHandler" should be used instead.

Support for non-default attributes when adding directory entries

Support per-entry compression settings

Entries are not reread on update

不支持分卷如：.z01 .z02

Make it a cocoapod

decompression of 7z files

hello can i get some working examples for decompression of 7z files from this library for ios
my email id - [email protected]

Support anti-entries

Request : 7zip benchmark on iOS

I don't know if this project is still alive.
If can, I'd like to request to make it 7zip benchmark on SVZDemo-iOS.

Support Carthage

Progress tracking

@lvsti does this framework support progress tracking? I don't think it does but just in case I've missed it.

Add API documentation

...as soon as appledoc is back from the dead

Broken build on Xcode 10

#include <windows.h> is not resolved, header search paths should be updated

Define behavior of entry objects on update

Password encrypted 7zip arch withe encrypted filenames?

Hey, thanks for product! Can you tell me, please, is there a way to create password-encrypted archive with encrypted filenames inside? Maybe you can suggest me another objc implementation?

Support entry-level password protection

Add some tests, for god's sake
