Preliminary

The Goal is to manage SME translations with Pootle hosted on contribs.org.

Once we have everything worked out how to interact with pootle and the formmagick stuff then I'll get something up on contribs.org that everyone can use. It would be really nice if we could automate the extraction/import of files that need to be translated into pootle but first things first.

Pootle Usage

Test pootle site: http://www.unixlan.com.ar:8888

untranslated words

click "Show Editing Functions" and finally at "Quick Translate" for each file or whole language.

Also you can see the suggestions clicking at "Review Suggestions".

click on one of the links offered and fix them

See http://translate.sourceforge.net/wiki/guide/pofilter_examples and http://translate.sourceforge.net/wiki/guide/translation/commonerrors

Merging new strings

Add, remove or modify strings in the template/*.pot file then click 'update from template'.

New strings are added
modified strings use existing data and made fuzzy (i think)
deleted strings are moved to the bottom of the file and commented out with #~

Formagick

Normando suggested a few tools, I'm using XML2PO, see the others in the history http://wiki.contribs.org/index.php?title=Talk:Pootle&oldid=7649#I_need_your_help

XML2PO

( http://linux.die.net/man/1/xml2po )

I have packaged for a better installation. You can download from 

http://mirror.contribs.org/smeserver/contribs/nhall/sme7/contribs/pootle/rpm/gnome-doc-utils-0.12.0-1.noarch.rpm

Before try, you must edit a few lines.

/usr/share/xml2po/empty.py 

Line 27 from "return []" to "return ['base']"
Line 31 from "return []" to "return ['trans']"
Line 35 leave "return []"
Line 39 from "return []" to "return ['trans']"

Create .po and export xml

To test the lexicons 

xml2po -m empty -e -o backup.po backup

View the new bakup.po file in the new PO format. Excellent. Now you can translate PO with pootle, and return again to formmagick panel with this command: 

xml2po -p backup.po backup > backup.new

As you can see, if you not translate backup.po, new_backup file is equal to original backup file, BUT with one difference, backup.new file has added a line at the header: We remove this line with newxml 

<?xml version="1.0" encoding="utf-8"?>

shell scripts

xml2po ignores tags such as CDATA, CDATA does not appear at the PO file.

The workaround is to find and replace the problem code

Create a clean .po file with newpo, either edit your lexicon or add s///g commands to workaround new problems

After you have a clean english .po you could use that as a template and copy and paste the translation in. A better idea is to write a merge tool see below

newpo

#!/bin/bash
#
#SME Server Create lexocon .po 
 
if  [ -f $1 ]
then
  #convert to UTF-8 while working on pootle
  mv $1 $1.bak
  /usr/bin/iconv -f ISO-8859-1 -t UTF-8 $1.bak > $1

  #echo "Remove CDATA and reformat problem codes in $1"
  perl -pi -e 's/<!\[CDATA\[/STARTCDATA/g' $1
  perl -pi -e 's/\]\]>/ENDCDATA/g' $1
  perl -pi -e 's/\&/AMP/g' $1
  perl -pi -e 's/P\>/p\>/g' $1
  perl -pi -e 's/A\>/a\>/g' $1
  perl -pi -e 's/\<(br|BR)\>/breeak/g' $1
  perl -pi -e 's/\<\/(font|FONT)\>//g' $1

  #echo "Create $1.po"
  xml2po -m empty -e -o $1.po $1

  #echo "Replacing CDATA in $1"
  perl -pi -e 's/STARTCDATA/<!\[CDATA\[/g' $1.po
  perl -pi -e 's/ENDCDATA/\]\]>/g' $1.po
  perl -pi -e 's/AMP/\&/g' $1.po
  perl -pi -e 's/breeak/\<bXr\>/g' $1.po  #wiki display error, fixme

  #basic testing
  A=`cat $1.bak |grep '<entry>' |wc -l`
  B=`cat $1.po |grep msgid |wc -l`
  C=`expr $B - 1`
  echo "entries $A, msgid $C"

  if  [ $A -ne $C ]
  then
   echo "Errors in formatting"
   tail $1.po
  fi
 
  #restore original
  mv $1.bak $1

  if  [ ${#2} -gt 0 ]
  then
   echo "<base> entries"
   cat $1 |grep base |sort
  fi

 else
 #print usage informamtion 
 echo "Usage: $0 LexiconFilename"
 echo "Usage: $0 LexiconFilename check"
fi
I am wondering why we are using perl to replace as we can also use sed and if readability is not an issue we can do the whole CDATA tag conversin at once
sed -e 's/<!\[CDATA\[/STARTCDATA/g' -e 's/\]\]>/ENDCDATA/g' -e 's/\&>/AMP/g' < original.file > conversion.file
And back
sed -e 's/STARTCDATA/<!\[CDATA\[/g' -e 's/ENDCDATA/\]\]>/g' -e 's/AMP/\&/g' < conversion.file > new.file
yes but there are more conversions, so it was easier to operate on the one file, efficiency isn't a concern

newpomerge

The aim of this is to take a blank en .po and merge in the values for a translation .po

en.po has 

msgid "Yes"
msgstr ""

fr.po has 

msgid "Oui"
msgstr ""

we want fr.po to look like 

msgid "Yes"
msgstr "Oui"

We can't assume the translation will be in the same order, so it involves looking back at the lexicon base field to do the match

or rewriting the fr lexicon first so it is in the same order, with empty fields if necessary, then you can just go through in order picking out records.

Sample .po output attached, it will always be in this format (but translation msgid's may be missing or out of order) 

msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"POT-Creation-Date: 2008-02-04 02:31+1100\n"

yum

newxml needs a parameter to set: lang="fr"
why doesn't this work ?
xml2po -l fr -p yum.po yum > yum.xml
-l --language=LANG Set language of the translation to LANG
you can't have a base equal to a trans, needs a new bug (if pootle goes ahead)
most en base lexicons do this,
easy fix is to tweak the trans for Form_Title, capitalise or punctuate
-<trans>Software installer</trans>

Console

update all .po files

Templates have been implemented with up to date strings,
now it's over to users to translate them


.po file names are inconsistent, SV & FR add .tmpl.po

.tmpl.po is correct, other languages have been updated


Use UTF-8 for console .po files

Pootle has problems with the current charset=iso-8859-1
we now use UTF-8

revision control using CVS/SVN

Today I had a quick look at the pootle pages and found a wiki as well, which has some valuable information like for instance revision control using CVS/SVN: http://translate.sourceforge.net/wiki/pootle/version_control - Cactus 03:26, 25 January 2008 (MST)

progress

we'll look at this later, perhaps starting with contribs

Remarks

Translation Workflow

Draft suggestions ...

The original files are in cvs.

.po files

  • gettext strings are in various files in cvs, currently we think we have them all in pootle as .pot template files
we need a script to search a maintained list of files to extract current gettext strings
this may find missing (or modified) strings or remove old ones saving on pointless translations
  • existing translations have been placed in pootle and merged with the templates
this shows missing translations very nicely and is ready for user testing
  • all .po files have been converted to UTF-8, they can be converted back easily if necessary
  • changes to original files, ie changed gettext strings, have to be tracked as usual in the bug tracker
these are imported into the templates, other languages are updated with a click
  • at some point we diff against cvs po files, the patch is checked and applied.


FormMagick files

  • these are XML files with a <base> and <trans> pair of strings, these can be converted to .po files with some work
  • some rough scripts are being worked on above, there may be others on the net waiting to be found...
we need to clean up some inconsistencies in the english lexicons and they will be our .pot templates
we need to script the conversion of existing translations into .po files, discussed above
  • all .po files have been converted to UTF-8, they can be converted back easily if necessary
  • changes to original files, have to be tracked as usual in the bug tracker
the following is speculative ...
these are imported into the .pot templates, other languages are updated with a click
I think any new <base> strings have to be added to the cvs xml file for each language
  • at some point we run xml2po to apply the new translation back to the xml file,
then diff against cvs, make patch, check and apply

Pootle issues

UTF-8

Bug created, 'Use UTF-8 for console .po files' http://bugs.contribs.org/show_bug.cgi?id=3858

SME Translation files currently use iso-8859-1
we currently convert any file in pootle to UTF-8
we can convert back when returning to SME if necessary, by adding one line in a script.

Testing Pootle I have found a few issues. I will try to describe.

Pootle (and Translation Toolkit used by Pootle) use as default a charset UTF-8. Everytime I have create a new language translation, Pootle parse from templates encoding as UTF-8. Everytime I have "Update from templates" the target PO files are updated as UTF-8, and if target has set charset=iso-8859-1, it is then corrupted. I can't found a method to set Pootle to use ISO-8859-1 as default. Because this, and to avoid these issues I have decide to use UTF-8 as charset in Pootle. Please see http://translate.sourceforge.net/wiki/guide/locales/glibc?s=charset#editing

Not only Pootle. Every desktop translation tool set UTF-8 as default charset.

If you want to merged or override a PO file, convert to UTF-8 (if not yet). Then you can upload without corrupt the target file.

One note for admins when Pootle run at contribs.org: I suggest to use a tool for convert from UTF-8 to ISO-8859-1 before make a new language rpm update package (if gettext can't support utf-8 encoding).

I have use this great script to convert between any charset files in a directory: 

#!/bin/bash

#./dir_iconv.sh dir cp1251 utf8 - converts all files from directory dir .. cp1251 (windows-1251) to utf8.

ICONVBIN='/usr/local/bin/iconv' # path to iconv binary

if [ $# -lt 3 ]
then
    echo "$0 dir from_charset to_charset"
    exit
fi

for f in $1/*
do
    if test -f $f
    then
        echo -e "\nConverting $f"
        /bin/mv $f $f.old
        $ICONVBIN -f $2 -t $3 $f.old > $f
    else
        echo -e "\nSkipping $f - not a regular file";
    fi
done

This apply also to panels (if formmagick can't support UTF-8 encoding)

There is an open posibility to modify Pootle or translation toolkit to make this automatically, but I don't know how to do. --Normando Hall 12:45, 2 February 2008 (MST)

  1. . Formmagick supports UTF-8: http://search.cpan.org/~mitel/CGI-FormMagick-0.89/lib/CGI/FormMagick.pm
  2. . GetText does support UTF-8 as well: http://www.gnu.org/software/gettext/manual/gettext.html#Charset-conversion
It is quite common for translations/lexicons to be in UTF8 as this is a well known locale independent character set, probably also the reason why Pootle is sticking to UTF-8. - Cactus 15:01, 2 February 2008 (MST)
