Имя (Name)
dpkg-parsechangelog - parse Debian changelog files
Синопсис (Synopsis)
dpkg-parsechangelog
[option...]
Описание (Description)
dpkg-parsechangelog
reads and parses the changelog of an unpacked
Debian source tree and outputs the information in it to standard
output in a machine-readable form.
Параметры (Options)
-l
, --file
changelog-file
Specifies the changelog file to read information from. A
'-' can be used to specify reading from standard input.
The default is debian/changelog
.
-F
changelog-format
Specifies the format of the changelog. By default the
format is read from a special line near the bottom of the
changelog or failing that defaults to the debian
standard
format. See also CHANGELOG FORMATS
.
-L
libdir
Obsolete option without effect (since dpkg 1.18.8).
Setting the perl environment variables PERL5LIB
or PERLLIB
has a similar effect when looking for the parser perl
modules.
-S
, --show-field
field
Specifies the name of the field to show (since dpkg
1.17.0). The field name is not printed, only its value.
-?
, --help
Show the usage message and exit.
--version
Show the version and exit.
Parser Options
The following options can be used to influence the output of the
changelog parser, e.g. the range of entries or the format of the
output.
--format
output-format
Set the output format. Currently supported values are dpkg
and rfc822
. dpkg
is the classic output format (from
before this option existed) and the default. It consists
of one paragraph in Debian control format (see
deb-control(5)). If more than one entry is requested, then
most fields are taken from the first entry (usually the
most recent entry), except otherwise stated:
Source:
pkg-name
Version:
version
Distribution:
target-distribution
Urgency:
urgency
The highest urgency of all included entries is
used, followed by the concatenated (space-
separated) comments from all the versions
requested.
Maintainer:
author
Date:
date
The date of the entry as a string, as it appears in
the changelog. With a strptime(3) format "%a, %d
%b %Y %T %z
", but where the day of the week might
not actually correspond to the real day obtained
from the rest of the date string. If you need a
more accurate representation of the date, use the
Timestamp
field, but take into account it might not
be possible to map it back to the exact value in
this field.
Timestamp:
timestamp
The date of the entry as a timestamp in seconds
since the epoch (since dpkg 1.18.8).
Closes:
bug-number
The Closes fields of all included entries are
merged.
Changes:
changelog-entries
The text of all changelog entries is concatenated.
To make this field a valid Debian control format
multiline field empty lines are replaced with a
single full stop and all lines is intended by one
space character. The exact content depends on the
changelog format.
The Version
, Distribution
, Urgency
, Maintainer
and Changes
fields are mandatory.
There might be additional user-defined fields present.
The rfc822
format uses the same fields but outputs a
separate paragraph for each changelog entry so that all
metadata for each entry is preserved.
--reverse
Include all changes in reverse order (since dpkg 1.19.1).
Note: for the dpkg
format the first entry will be the most
ancient entry.
--all
Include all changes. Note: other options have no effect
when this is in use.
-s
, --since
version
-v
version
Include all changes later than version.
-u
, --until
version
Include all changes earlier than version.
-f
, --from
version
Include all changes equal or later than version.
-t
, --to
version
Include all changes up to or equal than version.
-c
, --count
number
-n
number
Include number entries from the top (or the tail if number
is lower than 0).
-o
, --offset
number
Change the starting point for --count
, counted from the
top (or the tail if number is lower than 0).
CHANGELOG FORMATS
It is possible to use a different format to the standard one, by
providing a parser for that alternative format.
In order to have dpkg-parsechangelog
run the new parser, a line
must be included within the last 40 lines of the changelog file,
matching the Perl regular expression: '\schangelog-
format:\s+([0-9a-z]+)\W
'. The part in parentheses should be the
name of the format. For example:
@@@ changelog-format: otherformat @@@
Changelog format names are non-empty strings of lowercase
alphanumerics ('a-z0-9').
If such a line exists then dpkg-parsechangelog
will look for the
parser as a Dpkg::Changelog::
Otherformat perl module; it is an
error for it not being present. The parser name in the perl
module will be automatically capitalized. The default changelog
format is debian
, and a parser for it is provided by default.
The parser should be derived from the Dpkg::Changelog class and
implement the required documented interface.
If the changelog format which is being parsed always or almost
always leaves a blank line between individual change notes, these
blank lines should be stripped out, so as to make the resulting
output compact.
If the changelog format does not contain date or package name
information this information should be omitted from the output.
The parser should not attempt to synthesize it or find it from
other sources.
If the changelog does not have the expected format the parser
should error out, rather than trying to muddle through and
possibly generating incorrect output.
A changelog parser may not interact with the user at all.
Примечание (Note)
All Parser Options
except for -v
are only supported since dpkg
1.14.16.
Short option parsing with non-bundled values available only since
dpkg 1.18.0.
Окружение (Environment)
DPKG_COLORS
Sets the color mode (since dpkg 1.18.5). The currently
accepted values are: auto
(default), always
and never
.
DPKG_NLS
If set, it will be used to decide whether to activate
Native Language Support, also known as
internationalization (or i18n) support (since dpkg
1.19.0). The accepted values are: 0
and 1
(default).
Файлы (Files)
debian/changelog
The changelog file, used to obtain version-dependent
information about the source package, such as the urgency
and distribution of an upload, the changes made since a
particular release, and the source version number itself.
