debcheckout - checkout the development repository of a Debian
package
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-Hg: http://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
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 (arch),
Bazaar (bzr), CVS (cvs), Darcs (darcs), Git (git), Mercurial (hg) and
Subversion (svn).
GENERAL OPTIONS
- -a, --auth
- Work in authenticated mode; this means that for known repositories (mainly
those hosted on https://salsa.debian.org) URL rewriting is
attempted before checking out, to ensure that the repository can be
committed to. For example, for Git repositories hosted on Salsa this means
that git@salsa.debian.org:...git will be used instead of
https://salsa.debian.org/...git.
There are built-in rules for salsa.debian.org,
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 "git");
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 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.
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 is used to configure the "authenticated
mode" location for repositories. The Debian repositories on
salsa.debian.org are implicitly defined, as is github.com.
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.
