NAME

debcheckout - checkout the development repository of a Debian package

SYNOPSIS

debcheckout [OPTIONS] PACKAGE [DESTDIR]
debcheckout [OPTIONS] REPOSITORY_URL [DESTDIR]
debcheckout --help

DESCRIPTION

debcheckout retrieves the information about the Version Control System used to maintain a given Debian package (the PACKAGE 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 PACKAGE directory; this can be overridden by providing the DESTDIR 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-Git: git://git.debian.org/git/pkg-vim/vim.git, 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 PACKAGE=VERSION.

If you already know the URL 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 URL; if they fail, you might want to override the guessed type using -t.

The currently supported version control systems are: arch, bzr, cvs, darcs, git, hg, svn.

OPTIONS

GENERAL OPTIONS
-a, --auth
Work in authenticated mode; this means that for known repositories (mainly those hosted on http://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/....
-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.

-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
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 mutliple files.

VCS-SPECIFIC OPTIONS

GIT-SPECIFIC OPTIONS

--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.
