| These are Haskell bindings to [libarchive](https://github.com/libarchive/libarchive). | ||
|
|
||
| This contains Haskell bindings to | ||
| [libarchive](http://libarchive.org/). It was created as an alternative to | ||
| [tar](http://hackage.haskell.org/package/tar) and | ||
| [tar-conduit](http://hackage.haskell.org/package/tar-conduit), but it supports | ||
| more archive formats. | ||
| This project is separated into two packages: | ||
|
|
||
| It has a high-level Haskell API for creating and unpacking archives in addition | ||
| to the C API. Like the `tar` package, it can stream from lazy `ByteString`s. | ||
| * `libarchive`: the Haskell bindings (this is what you want to depend on) | ||
| * `libarchive-clib`: bundled C sources to avoid depending on system libarchive | ||
| * `zlib-clib`: bundled C sources to avoid depending on system zlib | ||

||
| ## Hacking | ||
| ## Installing from Git | ||
|
|
||
| To run the test suite, first run | ||
| To build this package using Cabal directly from Git, you must run `autoreconf -i` | ||
| in the `libarchive-clib/` subdirectory before the usual Cabal build steps | ||
| (cabal {configure,build,install}). The program `autoreconf` is part of | ||
| [GNU autoconf](https://www.gnu.org/software/autoconf/). There is no need to | ||
| run the configure script: cabal configure will do this for you. | ||
|
|
||
| ``` | ||
| make | ||
| ``` | ||
|
|
||
| to download test data. | ||
|
|
||
| ## Performance | ||
|
|
||
| `libarchive` is faster than `tar` or `tar-conduit` when unpacking archives. | ||
| If you're using a `cabal.project` you can add the following section: | ||
