- archive_open(+Data, +Mode, -Archive, +Options) is det
- Open the archive in Data and unify Archive with a handle to the
opened archive. Data is either a file name (as accepted by open/4)
or a stream that has been opened with the option
type(binary). If Data is an already open stream, the caller is responsible for closing it (but see optionclose_parent(true)) and must not close the stream until after archive_close/1 is called. Mode is eitherreadorwrite. Details are controlled by Options. Typically, the optionclose_parent(true)is used to also close the Data stream if the archive is closed using archive_close/1. For other options when reading, the defaults are typically fine - for writing, a valid format and optional filters must be specified. The optionformat(raw)must be used to process compressed streams that do not contain explicit entries (e.g., gzip'ed data) unambibuously. Therawformat creates a pseudo archive holding a single member nameddata.- close_parent(+Boolean)
- If this option is
true(defaultfalse), Data stream is closed when archive_close/1 is called on Archive. If Data is a file name, the default istrue. - filters(+Filters)
- Support the filters in the list Filters. In read mode, if no
filter is provided,
allis assumed. In write mode,noneis assumed and at most one filter is allowed. Supported values areall,bzip2,compress,gzip,grzip,lrzip,lzip,lzma,lzop,none,rpm,uuandxz. - formats(+Formats)
- Support the formats in the list Formats. In write mode, you must
supply a single format. If no format is provided,
allis assumed for read mode. Note thatalldoes not includerawandmtree. To open both archive and non-archive files,alltogether withrawand/ormtreemust be specified. Supported values areall,7zip,ar,cab,cpio,empty,gnutar,iso9660,lha,mtree,rar,raw,tar,xarandzip. - filter(+Filter)
- format(+Format)
- compression(+Filter)
- Deprecated. Add a single filter or format. Repeating these options to support multiple filters/formats is deprecated in favour of filters/1 and formats/1. compression/1 is a synonym for filter/1.
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 or permission error if the (explicitly) requested format or filter is not supported.
- Errors
- -
domain_error(filter, Filter)if the requested filter is invalid (e.g.,allfor writing). - -
domain_error(format, Format)if the requested format type is not supported. - -
