AllApplicationManualNameSummaryHelp

Availability::- use_module(library(archive)).(can be autoloaded)
Source[det]archive_open(+Data, +Mode, -Archive, +Options)
Open the archive in Data and unify Archive with a handle to the opened archive. Data is either a file or a stream that contains a valid archive. Details are controlled by Options. Typically, the option close_parent(true) is used to close stream if the archive is closed using archive_close/1. For other options, the defaults are typically fine. The option format(raw) must be used to process compressed streams that do not contain explicit entries (e.g., gzip'ed data) unambibuously. The raw format creates a pseudo archive holding a single member named data.
close_parent(+Boolean)
If this option is true (default false), Stream is closed if archive_close/1 is called on Archive.
compression(+Compression)
Synomym for filter(Compression). Deprecated.
filter(+Filter)
Support the indicated filter. This option may be used multiple times to support multiple filters. In read mode, If no filter options are provided, all is assumed. In write mode, none is assumed. Supported values are all, bzip2, compress, gzip, grzip, lrzip, lzip, lzma, lzop, none, rpm, uu and xz. The value all is default for read, none for write.
format(+Format)
Support the indicated format. This option may be used multiple times to support multiple formats in read mode. In write mode, you must supply a single format. If no format options are provided, all is assumed for read mode. Note that all does not include raw and mtree. To open both archive and non-archive files, both format(all) and format(raw) and/or format(mtree) must be specified. Supported values are: all, 7zip, ar, cab, cpio, empty, gnutar, iso9660, lha, mtree, rar, raw, tar, xar and zip. The value all is default for read.

Note that the actually supported compression types and formats may vary depending on the version and installation options of the underlying libarchive library. This predicate raises a domain error if the (explicitly) requested format is not supported.

Errors
- domain_error(filter, Filter) if the requested filter is not supported.
- domain_error(format, Format) if the requested format type is not supported.
