SYNOPSIS
- dose-ceve [-h] [-v] [-c pkgspec] [-r pkgspec] [--depth=n] [-T format] [-G graph type] [-o filename] input-spec [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.input-spec is a url specifying the input format and the file to get the input from. For a possible list of schemes, see the -t parameter.
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)
OPTIONS
MISC OPTIONS
- -h, --help
- This option displays the help message.
- -v, --verbose
- Be verbose. This option can be repeated for more verbosity.
- --version
- Show program's version and exit.
- --progress
- Print progress bars.
- --timers
- Print timing information.
- --quiet
- Do no print any messages.
INPUT OPTIONS
Dose3 accepts files compressed with gzip(1) or bzip2(1), depending on compile-time options.- -t input-spec
- Select the input type. Possible values are:
- .
- cudf Cudf file format
- .
- pef PEF file format. The PEF format (Package Exchange Format) is a generic 822 file format used to encode package dependencies. deb, opam, debsrc and edsp are all based on the pef format
- .
- csw OpenCSW Solaris packages binary format
- .
- opam Opam Package universe in Opam/PEF format. This format is a 822 textual format encoding the opam universe.
- .
- deb for Debian binary package files, also known as Packages files.
- .
- debsrc for Debian source package files, also knows as Sources files.
- .
- edsp apt-get External Dependency Solver Protocol
- .
- hdlist RPM hdlists. Binary file format.
- .
- synthesis urpmi synthesis hdlists. XML Based format
- --trim
- Consider only installable packages.
- --latest n
- Consider only the latest -n most recent versions of each package, older versions of packages are ignored.
- -c, --cone=vpkglist
-
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 vpkglist.
Example: =over 12
- -c 'golang-golang-x-tools (= 1:0.0~git20150716.0.87156cb+dfsg1-4),golang-golang-x-tools-dev'
- -r, --rcone=vpkglist
- Using the same syntax as in -c, this option use the reverse dependency relation to make the transitive closure.
- --depth n
- In combination with the -c or -r options, this specifies the maximum depth for the transitive closure.
- --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"
-
OUTPUT OPTIONS
- -o, --outfile=filename
- Instead of stdout, send output to the file filename.
- -d, --outdir=directory
- Set the output directory (default current directory)
- --dot
- Save the explanation graph (one for each package) in dot format.
- -G graph type
- Specifies the graph type format to compute. This option must be used together with the option -T dot|gml|grml. Default is syn. 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.
- .
- strdeps the strong dependency graph. A package p strong depends on q iff p cannot be installed if q is not installed.
- .
- strcnf
- .
- conj the conjunctive graph where only conjunctive dependencies are considered.
- .
- dom
- -T format
- Specifies the output format to use. Default is cnf. Possible values are:
- .
- cnf output in CNF format.
- .
- dimacs output in DIMACS format for CNF formulae.
- .
- cudf pretty-printed output in an RFC 822-like format
- .
- deb binary packages in deb822 format.
- .
- debsrc source packages in deb822 format.
- .
- dot a graph in Dot/GraphViz format.
- .
- gml a graph in GML format.
- .
- grml a graph in GraphML format.
- .
- table plain text output of three integer values: the universe size, the number of edges in the dependency graph, the number of conflicts in the universe.
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.
- --deb-host-arch=name
- Native/cross compile host architecture, defaults to native architecture.
- --deb-builds-from
- Add builds-from relationship of binary packages on source packages as dependency. This allows one to create graphs for bootstrapping purposes.
- -P, --deb-profiles=name[,name...]
- Comma separated list of activated build profiles.
- --deb-drop-b-d-indep
- Drop Build-Depends-Indep dependencies from Debian source packages.
EXAMPLES
Find all the reverse binary dependencies of the package patchutils:
dose-ceve --deb-native-arch amd64 -r patchutils -T deb \ deb:///var/lib/apt/lists/*_dists_sid_main_binary-amd64_Packages \ | grep-dctrl -n -s Package '' | sort -u
Find all the source packages that (directly or indirectly) build depend on patchutils:
dose-ceve -T debsrc --deb-native-arch=amd64 -r patchutils \ debsrc:///var/lib/apt/lists/*_dists_sid_main_source_Sources \ deb:///var/lib/apt/lists/*_dists_sid_main_binary-amd64_Packages \ | grep-dctrl -n -s Package '' | sort -u
Find the source packages (-T debsrc) that have in a relation builds-from with all the binary package in the reverse dependency cone of libssl-dev (a specific version constraint).
dose-ceve --deb-builds-from --deb-native-arch=amd64 -T debsrc \ -r 'libssl-dev (>= 0.9.8)' deb://Sid-amd64-Packages-050812.bz2 \ debsrc://Sid-Sources-050812.bz2
