dose-ceve - parse package metadata
dose-ceve [-h] [-v] [-c pkgspec] [-r pkgspec] [--depth=n] [-T format] [-G graph type] [-o filename] input-spec
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.
-h This option displays the help message. Can also be specified as --help. -v Be verbose. This option can be repeated for more verbosity. -c pkgspec The match of an atomic dependency (a package name p possibly together with a version constraint c) is the set of all packages in the repository with name p, and a version that satisfies the constraint c. The dependency cone of a package p is the set of all matches of all atomic dependencies of p, together with their respective dependency cones. The package specification pkgspec is a list of packages (separated by a semicolon), where each package is specified as follows: (name,version). This option extracts the union of the dependency cones of all packages selected by pkgspec. This option can also be specified as --cone=pkgspec. -r pkgspec Using the same syntax as in -c, this option use the reverse dependency relation to make the transitive closure. This option can also be specified as --rcone=pkgspec. --depth n In combination with the -c or -r options, this specifies the maximum depth for the transitive closure. -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. -t input-spec Select the input type. --request installation-request Specifies an installation request of the form "install: vpkglist" or "remove: vpkglist" or "upgrade: vpkglist" where vpkglist is a list of (real) packages possibly associated with a constraint. Ex.: bash (< 2.0), exim (= 3.1-debian1). This option can be repeated to specify install, remove and upgrade actions. Examples: --request "install: bash (< 2.0), exim (= 3.1-debian1)" --request "upgrade: apt-cudf" -G graph type Specifies the graph type format to compute. This option must be used together with the option -T dot|gml|grml. Possible values are: . syn for the syntactic graph where disjunctions nodes and conflicts are explicitly added to the graph. . pkg for the package graph where all dependencies are threated uniformely and conflicts are not added to the graph. . strong the strong dependency graph. A package p strong depends on q iff p cannot be installed if q is not installed. . conj the conjunctive graph where only conjunctive dependencies are considered. -o filename Instead of stdout, send output to the file filename. input-spec This is a URL specifying both the input format and the file to get the input from. Possible schemes are: . cudf for cudf files . deb for Debian package files (possibly compressed with gzip(1) or bzip2(1), depending on compile-time options for dose3) . debstdin for Debian package files read from standard input . edsp for apt-get External Dependency Solver Protocol . eclipse for Eclipse (p2) package files . hdlist for RPM hdlists . 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) DEBIAN SPECIFIC OPTIONS Multi-arch annotations are handled by dose-ceve. Packages whose's architecture is neither the native architecture nor in the list of foreign architectures (see below) are ignored. --deb-native-arch=name Specify the native architecture. The default behavior is to deduce the native architecture from the first package stanza in the input that has an architecture different from all. --deb-foreign-archs=name [,name] ... Specify a comma-separated list of foreign architectures. The default is an empty list of foreign architectures. --deb-ignore-essential By default all essential package are considered as a dependency of all packages in the universe. This option allows the user to ignore essential packages. 2016-01-03 CEVE(1)
