NAME
ceve - parse package metadata
SYNOPSIS
ceve [-h] [-v] [-c pkgspec] [-r pkgspec] [--depth=n] [-T format] [-G graph type] [-o
filename] input-spec [input-spec...]
DESCRIPTION
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 uniformly 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 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.
--deb-drop-b-d-arch
Drop Build-Depends-Arch 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).
