NAME

dose-ceve - parse package metadata

SYNOPSIS

dose-ceve [-h] [-v] [-c pkgspec] [-r pkgspec] [--depth=n] [-T format] [-G graph type] [-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.

-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.
