NAME¶

dose-ceve - parse package metadata

SYNOPSIS¶

dose-ceve [-h] [-v] [-e pkgspec] [-c pkgspec] [-r pkgspec] [--depth=n] [-t format] [-o filename] input-spec

DESCRIPTION¶

Dose-ceve is a generalized metadata parser. It reads package specifications, extracts package metadata from them, performs some manipulations, and outputs the package metadata in one of several formats.

OPTIONS¶

-h

This option displays the help message. Can also be specified as --help.

-v

Be verbose. This option can be repeated for more verbosity.

-e pkgspec

(Option Not Implemented Yet) Extract the transitive closure of packages connected (by conflict or dependency) to any of the packages that satisfy pkgspec. Such a package specification is a list of packages (separated by a semicolon), where each package is specified as follows: ( name,version). This option can also be specified as --extract= pkgspec.

-c pkgspec

Similar to the -c option, but only uses the dependency relation to make the transitive closure. This option can also be specified as --cone= pkgspec.

-r pkgspec

Similar to the -e and -c options, but uses the reverse dependency relation to make the transitive closure. This option can also be specified as --rcone= pkgspec.

--depth=n

In combination with the -e, -c or -r options, this specifies the maximum depth for the transitive closure. =item -t format

 

Specifies the output format to use. Possible values are dot for a graph output in Dot/GraphViz format, cnf for an output in CNF format, dimacs for an output in the DIMACS format for CNF formulae, and cudf for a pretty-print output in an RFC 822-like format. This option can also be specified as --outtype= format.

-o filename

Instead of stdout, send output to the file filename. This option can also be specified as --outfile= filename. =item input-spec

 

This is a URL specifying both the input format and the file to get the input from. Possible schemes are: =item *

 

cudf for cudf files =item *

 

deb for Debian package files (possibly compressed with gzip(1) or bzip2(1), depending on compile-time options for dose3) =item *

 

debstdin for Debian package files read from standard input =item *

 

eclipse for Eclipse (p2) package files =item *

 

pgsql for PostgreSQL databasess =item *

 

sqlite for sqlite databases

*

hdlist for RPM hdlists =item *

 

synth for urpmi synthesis hdlists
Some examples of URLs:

*

deb://Packages.gz (the Debian file packages.gz in the current directory)

*

cudf:///home/examples/cudf/test.cudf (the CUDF file /home/examples/cudf/test.cudf)

*

psql://user@db.mancoosi.org:723/packages (the database packages on host db.mancoosi.org on port 723, accessed as user user)
