|
||
|
||
Many systems (Solaris, Linux, Gnu) provide extensive tools that ease the
|
||
internationalization of C programs. Most of these tools are independent of
|
||
the programming language and can be used from within Python programs.
|
||
Martin von Loewis' work[1] helps considerably in this regard.
|
||
|
||
There's one problem though; xgettext is the program that scans source code
|
||
looking for message strings, but it groks only C (or C++). Python
|
||
introduces a few wrinkles, such as dual quoting characters, triple quoted
|
||
strings, and raw strings. xgettext understands none of this.
|
||
|
||
Enter pygettext, which uses Python's standard tokenize module to scan
|
||
Python source code, generating .pot files identical to what GNU xgettext[2]
|
||
generates for C and C++ code. From there, the standard GNU tools can be
|
||
used.
|
||
|
||
A word about marking Python strings as candidates for translation. GNU
|
||
xgettext recognizes the following keywords: gettext, dgettext, dcgettext,
|
||
and gettext_noop. But those can be a lot of text to include all over your
|
||
code. C and C++ have a trick: they use the C preprocessor. Most
|
||
internationalized C source includes a #define for gettext() to _() so that
|
||
what has to be written in the source is much less. Thus these are both
|
||
translatable strings:
|
||
|
||
gettext("Translatable String")
|
||
_("Translatable String")
|
||
|
||
Python of course has no preprocessor so this doesn't work so well. Thus,
|
||
pygettext searches only for _() by default, but see the -k/--keyword flag
|
||
below for how to augment this.
|
||
|
||
[1] http://www.python.org/workshops/1997-10/proceedings/loewis.html
|
||
[2] http://www.gnu.org/software/gettext/gettext.html
|
||
|
||
NOTE: pygettext attempts to be option and feature compatible with GNU
|
||
xgettext where ever possible. However some options are still missing or are
|
||
not fully implemented. Also, xgettext's use of command line switches with
|
||
option arguments is broken, and in these cases, pygettext just defines
|
||
additional switches.
|
||
|
||
Usage: pygettext [options] inputfile ...
|
||
|
||
Options:
|
||
|
||
-a
|
||
--extract-all
|
||
Extract all strings.
|
||
|
||
-d name
|
||
--default-domain=name
|
||
Rename the default output file from messages.pot to name.pot.
|
||
|
||
-E
|
||
--escape
|
||
Replace non-ASCII characters with octal escape sequences.
|
||
|
||
-D
|
||
--docstrings
|
||
Extract module, class, method, and function docstrings. These do
|
||
not need to be wrapped in _() markers, and in fact cannot be for
|
||
Python to consider them docstrings. (See also the -X option).
|
||
|
||
-h
|
||
--help
|
||
Print this help message and exit.
|
||
|
||
-k word
|
||
--keyword=word
|
||
Keywords to look for in addition to the default set, which are:
|
||
%(DEFAULTKEYWORDS)s
|
||
|
||
You can have multiple -k flags on the command line.
|
||
|
||
-K
|
||
--no-default-keywords
|
||
Disable the default set of keywords (see above). Any keywords
|
||
explicitly added with the -k/--keyword option are still recognized.
|
||
|
||
--no-location
|
||
Do not write filename/lineno location comments.
|
||
|
||
-n
|
||
--add-location
|
||
Write filename/lineno location comments indicating where each
|
||
extracted string is found in the source. These lines appear before
|
||
each msgid. The style of comments is controlled by the -S/--style
|
||
option. This is the default.
|
||
|
||
-o filename
|
||
--output=filename
|
||
Rename the default output file from messages.pot to filename. If
|
||
filename is `-' then the output is sent to standard out.
|
||
|
||
-p dir
|
||
--output-dir=dir
|
||
Output files will be placed in directory dir.
|
||
|
||
-S stylename
|
||
--style stylename
|
||
Specify which style to use for location comments. Two styles are
|
||
supported:
|
||
|
||
Solaris # File: filename, line: line-number
|
||
GNU #: filename:line
|
||
|
||
The style name is case insensitive. GNU style is the default.
|
||
|
||
-v
|
||
--verbose
|
||
Print the names of the files being processed.
|
||
|
||
-V
|
||
--version
|
||
Print the version of pygettext and exit.
|
||
|
||
-w columns
|
||
--width=columns
|
||
Set width of output to columns.
|
||
|
||
-x filename
|
||
--exclude-file=filename
|
||
Specify a file that contains a list of strings that are not be
|
||
extracted from the input files. Each string to be excluded must
|
||
appear on a line by itself in the file.
|
||
|
||
-X filename
|
||
--no-docstrings=filename
|
||
Specify a file that contains a list of files (one per line) that
|
||
should not have their docstrings extracted. This is only useful in
|
||
conjunction with the -D option above.
|
||
|
||
If `inputfile' is -, standard input is read.
