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.
no documented way to access them. It also preserves the order of
flags, if no flags are modified.
Replaced the fuzzy, c_format, and php_format fields with _flaghash,
and renamed the _flag field to _flagstr.
Flag-setting functions silently map unsupported values (e.g. 42) to
supported ones (e.g. 1), which they also return.
The c_format and php_format methods treat empty strings as 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.
It also recognizes conflicts that involve more than two msgstrs.
And it no longer outputs the msgids.
These changes make the output much shorter than before,
while still listing all the relevant information.
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<Locale::PO>; it looks bad in pod2text.
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
now be specified as --srcdir=top_srcdir (or --source-directory=top_srcdir
or -S top_srcdir). Changed po/Makefile to match.
This option can even be repeated; that resolves a BUGS item.
Changed po/Makefile to ignore exit codes from check-accelerator-contexts.pl.
Enabled bundling of options in Getopt::Long so that -Stop_srcdir works too.
The detailed documentation is now as POD in the scripts, and the README
just gives an overview and describes how the scripts relate to ELinks.
The intention here is to make the scripts more readily usable for programs
other than ELinks. The scripts now describe their licensing, too.
the same accelerator key to multiple buttons in a dialog box or
to multiple items in a menu. ELinks already has some support for
this but it requires the translator to run ELinks and manually
scan through all menus and dialogs. The attached changes make it
possible to quickly detect and list any conflicts, including ones
that can only occur on operating systems or configurations that
the translator is not currently using.
The changes have no immediate effect on the elinks executable or
the MO files. PO files become larger, however.
The scheme works like this:
- Like before, accelerator keys in translatable strings are
tagged with the tilde (~) character.
- Whenever a C source file defines an accelerator key, it must
assign one or more named "contexts" to it. The translations in
the PO files inherit these contexts. If multiple strings use
the same accelerator (case insensitive) in the same context,
that's a conflict and can be detected automatically.
- The contexts are defined with "gettext_accelerator_context"
comments in source files. These comments delimit regions where
all translatable strings containing tildes are given the same
contexts. There must be one special comment at the top of the
region; it lists the contexts assigned to that region. The
region automatically ends at the end of the function (found
with regexp /^\}/), but it can also be closed explicitly with
another special comment. The comments are formatted like this:
/* [gettext_accelerator_context(foo, bar, baz)]
begins a region that uses the contexts "foo", "bar", and "baz".
The comma is the delimiter; whitespace is optional.
[gettext_accelerator_context()]
ends the region. */
The scripts don't currently check whether this syntax occurs
inside or outside comments.
- The names of contexts consist of C identifiers delimited with
periods. I typically used the name of a function that sets
up a dialog, or the name of an array where the items of a
menu are listed. There is a special feature for static
functions: if the name begins with a period, then the period
will be replaced with the name of the source file and a colon.
- If a menu is programmatically generated from multiple parts,
of which some are never used together, so that it is safe to
use the same accelerators in them, then it is necessary to
define multiple contexts for the same menu. link_menu() in
src/viewer/text/link.c is the most complex example of this.
- During make update-po:
- A Perl script (po/gather-accelerator-contexts.pl) reads
po/elinks.pot, scans the source files listed in it for
"gettext_accelerator_context" comments, and rewrites
po/elinks.pot with "accelerator_context" comments that
indicate the contexts of each msgid: the union of all
contexts of all of its uses in the source files. It also
removes any "gettext_accelerator_context" comments that
xgettext --add-comments has copied to elinks.pot.
- If po/gather-accelerator-contexts.pl does not find any
contexts for some use of an msgid that seems to contain an
accelerator (because it contains a tilde), it warns. If the
tilde refers to e.g. "~/.elinks" and does not actually mark
an accelerator, the warning can be silenced by specifying the
special context "IGNORE", which the script otherwise ignores.
- msgmerge copies the "accelerator_context" comments from
po/elinks.pot to po/*.po. Translators do not edit those
comments.
- During make check-po:
- Another Perl script (po/check-accelerator-contexts.pl) reads
po/*.po and keeps track of which accelerators have been bound
in each context. It warns about any conflicts it finds.
This script does not access the C source files; thus it does
not matter if the line numbers in "#:" lines are out of date.
This implementation is not perfect and I am not proposing to
add it to the main source tree at this time. Specifically:
- It introduces compile-time dependencies on Perl and Locale::PO.
There should be a configure-time or compile-time check so that
the new features are skipped if the prerequisites are missing.
- When the scripts include msgstr strings in warnings, they
should transcode them from the charset of the PO file to the
one specified by the user's locale.
- It is not adequately documented (well, except perhaps here).
- po/check-accelerator-contexts.pl reports the same conflict
multiple times if it occurs in multiple contexts.
- The warning messages should include line numbers, so that users
of Emacs could conveniently edit the conflicting part of the PO
file. This is not feasible with the current version of
Locale::PO.
- Locale::PO does not understand #~ lines and spews warnings
about them. There is an ugly hack to hide these warnings.
- Jonas Fonseca suggested the script could propose accelerators
that are still available. This has not been implemented.
There are three files attached:
- po/gather-accelerator-contexts.pl: Augments elinks.pot with
context information.
- po/check-accelerator-contexts.pl: Checks conflicts.
- accelerator-contexts.diff: Makes po/Makefile run the scripts,
and adds special comments to source files.
I changed the %.gmo rule in po/Makefile to use $@ instead of a shell
variable, and made various tweaks in it to better support strange file
names, e.g. spaces in $(srcdir). I suppose other makefiles in ELinks and
other rules in po/Makefile do not support those, but one must start
somewhere. I don't think it will ever be feasible to support backslashes
and quotes without horrible contortions, but spaces and dashes should be
doable.
I also quoted the ~ in --check-accelerators=~ in case some shell might want
to expand it as the home directory. Bash 3.00.16(1) doesn't because the
word contains dashes.
According to the documentation, GNU Make uses them only for suffix rules,
which have been replaced with pattern rules in po/Makefile. The makefiles
included by po/Makefile do not define suffix rules, either.
Involves prefixing with $(srcdir) to some of the build rule variables. For
the builddir we create Makefiles which simply include the srcdir Makefile.
Add list make rule to get list of Makefiles to generate (find will get it
wrong for builddirs nested in srcdir).
There are still a few minor issues like the file paths echoed during make
install ...
Makes it more obvious which files are actually installed. MKINSTALLDIRS
still spurs out a lot of 'mkdir ...', which probably should also be
silenced when V=0.
