The --msgid-fallback mode still reports conflicts between msgid and msgstr strings, but the resulting suggestions can now include accelerators reserved by msgids; thus the translator won't be lured into avoiding accelerators that she'll be likely to replace anyway. Therefore, --msgid-fallback is now the default and can be turned off with the new option --no-msgid-fallback. After checking each file, check-accelerator-conflicts.pl displays a one-line summary of how many accelerators it checked and how many conflicts it found. This is primarily meant to warn people by displaying zeroes if if gather-accelerator-contexts.pl has not been run. Locale::PO::dump doesn't output an msgid if there isn't one.

=head1 DESCRIPTION
|
|
|
|
This module simplifies management of GNU gettext .po files and is an
|
|
alternative to using emacs po-mode. It provides an object-oriented
|
|
interface in which each entry in a .po file is a Locale::PO object.
|
|
|
|
=head2 Levels of Quoting
|
|
|
|
When you use methods of Locale::PO, you need to distinguish between
|
|
three possible levels of quoting strings. These levels are described
|
|
below. The descriptions also list how the following sample msgid
|
|
string would be quoted in each level.
|
|
|
|
msgid "The characters /\\ denote the \"AND\" operator.\n"
|
|
"Please enter all numbers in octal."
|
|
|
|
=over
|
|
|
|
=item FULLY-QUOTED
|
|
|
|
The same format as in a PO file: the string may consist of multiple
|
|
lines, and each line has double-quote characters around it and may
|
|
contain backslash sequences. Any double-quote or backslash characters
|
|
that should be part of the data must be escaped with backslashes.
|
|
|
|
The example in Perl syntax: C<qq("The characters /\\\\ denote the
|
|
\\"AND\\" operator.\\n"\n"Please enter all numbers in octal.")>
|
|
|
|
=item BACKSLASHED
|
|
|
|
The string may consist of multiple lines. The lines do not have
|
|
double-quote characters around them, but they may contain backslash
|
|
sequences. Any backslash characters that should be part of the data
|
|
must be escaped with backslashes, but double-quote characters must not.
|
|
|
|
The example in Perl syntax: C<qq(The characters /\\\\ denote the
|
|
"AND" operator.\\n\nPlease enter all numbers in octal.)>
|
|
|
|
=item NOT-QUOTED
|
|
|
|
This is the format that a C program would pass to the C<gettext>
|
|
function or output to a terminal device. Any remaining quotes are
|
|
part of the data itself, and backslash escapes have been replaced
|
|
with control characters. Locale::PO does not currently support
|
|
this quoting level.
|
|
|
|
The example in Perl syntax: C<qq(The characters /\\ denote the "AND"
|
|
operator.\nPlease enter all numbers in octal.)>

|
|
|
|
=item new
|
|
|
|
my Locale::PO $po = new Locale::PO;
|
|
my Locale::PO $po = new Locale::PO(%options);
|
|
|
|
Create a new Locale::PO object to represent a po entry.
|
|
You can optionally set the attributes of the entry by passing
|
|
a list/hash of the form:
|
|
|
|
-option=>value, -option=>value, etc.
|
|
|
|
Where options are msgid, msgstr, comment, automatic, reference, fuzzy,
|
|
c-format, and no-c-format. See accessor methods below. Currently, you
|
|
cannot set the "obsolete" or "php-format" flags via options.
|
|
|
|
To generate a po file header, add an entry with an empty
|
|
msgid, like this:
|
|
|
|
$po = new Locale::PO(-msgid=>'', -msgstr=>
|
|
"Project-Id-Version: PACKAGE VERSION\\n" .
|
|
"PO-Revision-Date: YEAR-MO-DA HO:MI +ZONE\\n" .
|
|
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\\n" .
|
|
"Language-Team: LANGUAGE <LL@li.org>\\n" .
|
|
"MIME-Version: 1.0\\n" .
|
|
"Content-Type: text/plain; charset=CHARSET\\n" .
|
|
"Content-Transfer-Encoding: ENCODING\\n");
|
|
|
|
Note that the C<msgid> and C<msgstr> must be in BACKSLASHED form.
|
|
|
|
=item msgid
|
|
|
|
$fully_quoted_string = $po->msgid;
|
|
# $backslashed_string = $po->dequote($fully_quoted_string);
|
|
$po->msgid($backslashed_string);
|
|
|
|
Set or get the untranslated string from the object.
|
|
|
|
The value is C<undef> if there is no such string for this message, not
|
|
even an empty string. If the message was loaded from a PO file, this
|
|
can occur if there are comments after the last C<msgid> line. The
|
|
loading functions warn about such omissions.
|
|
|
|
This method expects the new string in BACKSLASHED form
|
|
but returns the current string in FULLY-QUOTED form.
|
|
|
|
=item msgid_begin_lineno
|
|
|
|
$line_number = $po->msgid_begin_lineno;
|
|
|
|
Get the line number at which the C<msgid> string begins in the PO file.
|
|
This is undef if the entry was not loaded from a file.
|
|
There is currently no setter method for this field.
|
|
|
|
=item msgid_plural
|
|
|
|
$fully_quoted_string = $po->msgid_plural;
|
|
# $backslashed_string = $po->dequote($fully_quoted_string);
|
|
$po->msgid_plural($backslashed_string);
|
|
|
|
Set or get the untranslated plural string from the object. The value
|
|
is C<undef> if there is no plural form for this message.
|
|
|
|
This method expects the new string in BACKSLASHED form
|
|
but returns the current string in FULLY-QUOTED form.
|
|
|
|
=item msgstr
|
|
|
|
$fully_quoted_string = $po->msgstr;
|
|
# $backslashed_string = $po->dequote($fully_quoted_string);
|
|
$po->msgstr($backslashed_string);
|
|
|
|
Set or get the translated string from the object.
|
|
|
|
If the string has plural forms, then they are instead accessible via
|
|
C<msgstr_n>, and C<msgstr> normally returns C<undef>. However, if the
|
|
entry has been loaded from an incorrectly formatted PO file, then it
|
|
is also possible that both C<msgstr> and C<msgstr_n> return C<undef>,
|
|
or that they both return defined values. The loading functions warn
|
|
about such transgressions.
|
|
|
|
This method expects the new string in BACKSLASHED form
|
|
but returns the current string in FULLY-QUOTED form.
|
|
|
|
=item msgstr_begin_lineno
|
|
|
|
$line_number = $po->msgstr_begin_lineno;
|
|
|
|
Get the line number at which the C<msgstr> string begins in the PO file.
|
|
This is undef if the entry was not loaded from a file.
|
|
There is currently no setter method for this field.
|
|
|
|
=item msgstr_n
|
|
|
|
$fully_quoted_hashref = $po->msgstr_n;
|
|
# $backslashed_hashref = { %$fully_quoted_hashref };
|
|
# $_ = $po->dequote($_) foreach values(%$backslashed_hashref);
|
|
$po->msgstr_n($backslashed_hashref);
|
|
|
|
Get or set the translations if there are plurals involved. Takes and
|
|
returns a hashref where the keys are the 'N' case and the values are
|
|
the strings. eg:
|
|
|
|
$po->msgstr_n(
|
|
{
|
|
0 => 'found %d plural translations',
|
|
1 => 'found %d singular translation',
|
|
}
|
|
);
|
|
|
|
The value C<undef> should be treated the same as an empty hash.
|
|
Callers should neither modify the hash to which the returned reference
|
|
points, nor assume it to remain valid if C<msgstr_n> is later called
|
|
to install a new set of translations.
|
|
|
|
This method expects the new strings in BACKSLASHED form
|
|
but returns the current strings in FULLY-QUOTED form.
|
|
|
|
=item comment
|
|
|
|
$string = $po->comment;
|
|
$po->comment($string);
|
|
|
|
Set or get translator comments from the object.
|
|
|
|
If there are no such comments, then the value is C<undef>. Otherwise,
|
|
the value is a string that contains the comment lines delimited with
|
|
"\n". The string includes neither the S<"# "> at the beginning of
|
|
each comment line nor the newline at the end of the last comment line.
|
|
|
|
=item automatic
|
|
|
|
$string = $po->automatic;
|
|
$po->automatic($string);
|
|
|
|
Set or get automatic comments from the object (inserted by
|
|
emacs po-mode or xgettext).
|
|
|
|
If there are no such comments, then the value is C<undef>. Otherwise,
|
|
the value is a string that contains the comment lines delimited with
|
|
"\n". The string includes neither the S<"#. "> at the beginning of
|
|
each comment line nor the newline at the end of the last comment line.
|
|
|
|
=item reference
|
|
|
|
$string = $po->reference;
|
|
$po->reference($string);
|
|
|
|
Set or get reference marking comments from the object (inserted
|
|
by emacs po-mode or gettext).
|
|
|
|
If there are no such comments, then the value is C<undef>. Otherwise,
|
|
the value is a string that contains the comment lines delimited with
|
|
"\n". The string includes neither the S<"#: "> at the beginning of
|
|
each comment line nor the newline at the end of the last comment line.
|
|
|
|
=item fuzzy
|
|
|
|
$flag = $po->fuzzy;
|
|
$po->fuzzy($flag);
|
|
|
|
Set or get the fuzzy flag on the object ("check this translation").
|
|
When setting, use 1 to turn on fuzzy, and 0 to turn it off.
|
|
|
|
=item obsolete
|
|
|
|
$flag = $po->obsolete;
|
|
$po->obsolete($flag);
|
|
|
|
Set or get the obsolete flag on the object ("no longer used").
|
|
When setting, use 1 to turn on obsolete, and 0 to turn it off.
|
|
|
|
=item c_format
|
|
|
|
$tristate = $po->obsolete;
|
|
$po->obsolete($tristate);
|
|
|
|
Set or get the c-format or no-c-format flag on the object.
|
|
This can take 3 values: 1 implies c-format, 0 implies no-c-format,
|
|
and blank or undefined implies neither.
|
|
|
|
=item php_format
|
|
|
|
$tristate = $po->php_format;
|
|
$po->php_format($tristate);
|
|
|
|
Set or get the php-format or no-php-format flag on the object.
|
|
This can take 3 values: 1 implies php-format, 0 implies no-php-format,
|
|
and blank or undefined implies neither.
|
|
|
|
=item dump
|
|
|
|
print $po->dump;
|
|
|
|
Returns the entry as a string, suitable for output to a po file.
|
|
|
|
=item quote
|
|
|
|
$fully_quoted_string = $po->quote($backslashed_string);
|
|
|
|
Converts a string from BACKSLASHED to FULLY-QUOTED form.
|
|
Specifically, the quoted string will have all existing double-quote
|
|
characters escaped by backslashes, and each line will be enclosed in
|
|
double quotes. Preexisting backslashes will not be doubled.
|
|
|
|
=item dequote
|
|
|
|
$backslashed_string = $po->dequote($fully_quoted_string);
|
|
|
|
Converts a string from FULLY-QUOTED to BACKSLASHED form.
|
|
Specifically, it first removes the double-quote characters that
|
|
surround each line. After this, each remaining double-quote character
|
|
should have a backslash in front of it; the method then removes those
|
|
backslashes. Backslashes in any other position will be left intact.
|
|
|
|
=item load_file_asarray
|
|
|
|
$arrayref = Locale::PO->load_file_asarray($filename);
|
|
|
|
Given the filename of a po-file, reads the file and returns a
|
|
reference to a list of Locale::PO objects corresponding to the contents of
|
|
the file, in the same order.
|
|
|
|
If the file cannot be read, then this method returns C<undef>, and you
|
|
can check C<$!> for the actual error. If the file does not follow the
|
|
expected syntax, then the method generates warnings but keeps going.
|
|
Other errors (e.g. out of memory) may result in C<die> being called,
|
|
of course.
|
|
|
|
=item load_file_ashash
|
|
|
|
$hashref = Locale::PO->load_file_ashash($filename);
|
|
|
|
Given the filename of a po-file, reads the file and returns a
|
|
reference to a hash of Locale::PO objects corresponding to the contents of
|
|
the file. The hash keys are the untranslated strings (in BACKSLASHED form),
|
|
so this is a cheap way to remove duplicates. The method will prefer to keep
|
|
entries that have been translated.
|
|
|
|
This handles errors in the same way as C<load_file_asarray> does.
|
|
|
|
=item load_file
|
|
|
|
$ref = Locale::PO->load_file($filename, $ashash);
|
|
|
|
This method behaves as C<load_file_asarray> if the C<$ashash>
|
|
parameter is 0, or as C<load_file_ashash> if C<$ashash> is 1.
|
|
Your code will probably be easier to understand if you call either
|
|
of those methods instead of this one.
|
|
|
|
=item save_file_fromarray
|
|
|
|
$ok = Locale::PO->save_file_fromarray($filename, \@objects)
|
|
|
|
Given a filename and a reference to a list of Locale::PO objects,
|
|
saves those objects to the file, creating a po-file.
|
|
|
|
Returns true if successful.
|
|
Returns C<undef> and sets C<$!> if an I/O error occurs.
|
|
Dies if a serious error occurs.
|
|
|
|
=item save_file_fromhash
|
|
|
|
$ok = Locale::PO->save_file_fromhash($filename, \%objects);
|
|
|
|
Given a filename and a reference to a hash of Locale::PO objects,
|
|
saves those objects to the file, creating a po-file. The entries
|
|
are sorted alphabetically by untranslated string.
|
|
|
|
Returns true if successful.
|
|
Returns C<undef> and sets C<$!> if an I/O error occurs.
|
|
Dies if a serious error occurs.
|
|
|
|
=item save_file
|
|
|
|
$ok = Locale::PO->save_file($filename, $ref, $fromhash);
|
|
|
|
This method behaves as C<save_file_fromarray> if the C<$fromhash>
|
|
parameter is 0, or as C<save_file_fromhash> if C<$fromhash> is 1.
|
|
Your code will probably be easier to understand if you call either
|
|
of those methods instead of this one.

|
|
|
|
Rewrote the file parser. It now warns about various inconsistencies, and no longer relies on empty lines.
|
|
The parser writes directly to fields of Locale::PO objects, preserving internal newlines in strings. Changed C<dequote> to process all lines of multi-line strings.
|
|
The parser supports obsolete entries. Added the C<_obsolete> field and the C<obsolete> method. C<dump> comments the entry out if it is obsolete.
|
|
The parser preserves the original string of flags and scans it more carefully. Added the C<_flag> field. Implemented "no-php-format".
|

C<dump> dumps comments even if they are C<eq "0">.

|
|
Documented levels of quoting, and the exact behaviour of C<quote> and C<dequote>.
|
|
Documented the C<obsolete> method.
|
|
Documented error handling in C<load_file_asarray> and C<load_file_ashash>.
|
|
Documented when C<msgid>, C<msgstr> etc. can return C<undef>.

|
|
|
|
C<save_file> returns C<undef> and remembers C<$!> if C<print> fails.
|
|
C<load_file_asarray> saves line numbers of C<msgid> and C<msgstr>. New fields C<_msgid_begin_lineno> and C<_msgstr_begin_lineno>; new methods C<msgid_begin_lineno> and C<msgstr_begin_lineno>.
|
|
|
|
POD changes:
|
|
Revised the synopses of the methods, paying attention to levels of quoting.
|
|
Repeat the synopsis above the description of each method.
|
|
Never write C<< CZ<><Locale::PO> >>; it looks bad in B<pod2text>.
|
|
Documented that C<msgstr> normally returns C<undef> if there are plurals.
|
|
Documented the new methods C<msgid_begin_lineno> and C<msgstr_begin_lineno>.
|

Locale::PO now preserves unrecognized flags, although there is still no documented way to access them. It also preserves the order of flags, if no flags are modified. Replaced the C<fuzzy>, C<c_format>, and C<php_format> fields with C<_flaghash>, and renamed the C<_flag> field to C<_flagstr>.
|
|
Flag-setting functions silently map unsupported values (e.g. 42) to supported ones (e.g. 1), which they also return.
|
|
The C<c_format> and C<php_format> methods treat empty strings as C<undef>, rather than as 0.
|
|
Names of flags are case-sensitive, like in GNU Gettext.
|
|
|
|
POD changes:
|
|
Unlisted the bugs that have now been fixed.

|
|
|
|
The C<dump> method doesn't output an C<msgid> if there isn't one.

=head1 BUGS
|
|
|
|
If you C<load_file> then C<save_file>, the output file may have slight
|
|
cosmetic differences from the input file (an extra blank line here or there).
|
|
|
|
The C<quote> and C<dequote> methods assume Perl knows the encoding
|
|
of the string. If it doesn't, they'll treat each 0x5C byte as a
|
|
backslash even if it's actually part of a multibyte character.
|
|
Therefore, Locale::PO should parse the charset parameter from the
|
|
header entry, and decode the strings with that. It is unclear whether
|
|
the charset must be decoded even before the newlines and quotes are
|
|
parsed; this would mainly be a requirement with UTF-16, which GNU
|
|
Gettext doesn't support.
|
|
|
|
=head2 Almost Bugs
|
|
|
|
C<msgid_begin_lineno> and C<msgstr_begin_lineno> are read-only.
|
|
Perhaps there should also be ways to get the line numbers of the
|
|
other strings. Probably not line numbers of comments, though.
|
|
|
|
The C<msgid>, C<msgid_plural>, C<msgstr>, and C<msgstr_n> methods
|
|
output FULLY-QUOTED strings, but they expect BACKSLASHED strings as
|
|
input. It would be better to have both FULLY-QUOTED or both
|
|
BACKSLASHED; or perhaps C<< $po->msgid(-level => 'BACKSLASHED') >>.
|
|
|
|
Locale::PO discards all types of comments it does not recognize.
|
|
The B<msgmerge> program of GNU gettext-tools 0.14.3 does the same,
|
|
so perhaps it's not a problem.
