DESCRIPTION

debcheckout retrieves the information about the Version Control System used to maintain a given Debian package (the argument), and then checks out the latest (potentially unreleased) version of the package from its repository. By default the repository is checked out to the directory; this can be overridden by providing the argument.

The information about where the repository is available is expected to be found in Vcs-* fields available in the source package record. For example, the vim package exposes such information with a field like Vcs-Hg: hg.debian.org/hg/pkg-vim/vim, you can see it by grepping through apt-cache showsrc vim.

If more than one source package record containing Vcs-* fields is available, debcheckout will select the record with the highest version number. Alternatively, a particular version may be selected from those available by specifying the package name as

=.

If you already know the

of a given repository you can invoke debcheckout directly on it, but you will probably need to pass the appropriate -t flag. That is, some heuristics are in use to guess the repository type from the ; if they fail, you might want to override the guessed type using -t.

The currently supported version control systems are: Arch (arch), Bazaar (bzr),

(cvs), Darcs (darcs), Git (git), Mercurial (hg) and Subversion (svn).

OPTIONS

-a, --auth

Work in authenticated mode; this means that for known repositories (mainly those hosted on alioth.debian.org)

URL

rewriting is attempted before checking out, to ensure that the repository can be committed to. For example, for Subversion repositories hosted on alioth this means that svn+ssh://svn.debian.org will be used instead of svn://svn.debian.org/....

There are built-in rules for alioth.debian.org and github.com. Other hosts can be configured using

DEBCHECKOUT_AUTH_URLS

.

-d, --details

Only print a list of detailed information about the package repository, without checking it out; the output format is a list of fields, each field being a pair of TAB-separated field name and field value. The actual fields depend on the repository type. This action might require a network connection to the remote repository.

Also see -p. This option and -p are mutually exclusive.

-h, --help

Print a detailed help message and exit.

-p, --print

Only print a summary about package repository information, without checking it out; the output format is TAB-separated with two fields: repository type, repository

URL.

This action works offline, it only uses ``static'' information as known by

APT

's cache.

Also see -d. This option and -d are mutually exclusive.

-P package, --package package

When checking out a repository

URL,

instead of trying to guess the package name from the

URL,

use this package name.

-t

TYPE

, --type

TYPE

Override the repository type (which defaults to some heuristics based on the

URL

or, in case of heuristic failure, the fallback ``svn''); should be one of the currently supported repository types.

-u

USERNAME

, --user

USERNAME

Specify the login name to be used in authenticated mode (see -a). This option implies -a: you don't need to specify both.

-f

FILE

, --file

FILE

Specify that the named file should be extracted from the repository and placed in the destination directory. May be used more than once to extract multiple files.

--source=never|auto|download-only|always

Some packages only place the debian directory in version control. debcheckout can retrieve the remaining parts of the source using apt-get source and move the files into the checkout.

never

Only use the repository.

auto (default)

If the repository only contains the debian directory, retrieve the source package, unpack it, and also place the .orig.tar.gz file into the current directory. Else, do nothing.

download-only

Always retrieve the .orig.tar.gz file, but do not unpack it.

always

Always retrieve the .orig.tar.gz file, and if the repository only contains the debian directory, unpack it.

VCS-SPECIFIC

GIT-SPECIFIC

--git-track

BRANCHES

Specify a list of remote branches which will be set up for tracking (as in git branch --track, see git-branch(1)) after the remote Git repository has been cloned. The list should be given as a space-separated list of branch names.

As a shorthand, the string "*" can be given to require tracking of all remote branches.

CONFIGURATION VARIABLES

The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables. Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently recognised variables are:

DEBCHECKOUT_AUTH_URLS

This variable should be a space separated list of Perl regular expressions and replacement texts, which must come in pairs:

REGEXP

TEXT

REGEXP

TEXT

... and so on. Each pair denotes a substitution which is applied to repository URLs if other built-in means of building URLs for authenticated mode (see -a) have failed.

References to matching substrings in the replacement texts are allowed as usual in Perl by the means of $1, $2, ... and so on.

This setting can be used to enable authenticated mode for most repositories out there. Note that the Debian repositories on alioth.debian.org ($vcs.debian.org) are implicitly defined.

Here is a sample snippet suitable for the configuration files:

 DEBCHECKOUT_AUTH_URLS='
  ^\w+://(svn\.example\.com)/(.*)    svn+ssh://$1/srv/svn/$2
  ^\w+://(git\.example\.com)/(.*)    git+ssh://$1/home/git/$2
 '

Note that whitespace is not allowed in either regexps or replacement texts. Also, given that configuration files are sourced by a shell, you probably want to use single quotes around the value of this variable.

DEBCHECKOUT_SOURCE

This variable determines under what scenarios the associated orig.tar.gz for a package will be downloaded. See the --source option for a description of the values.

DEBCHECKOUT_USER

This variable sets the username for authenticated mode. It can be overridden with the --user option. Setting this variable does not imply the use of authenticated mode, it still has to be activated with --auth.
