Great. Version 1.30 is up to date


It has been not so simple.
gettext does not like messages starting with - (minus)
so I had to change the text, see picture
But using the new momanager_enhanced was fun. Very Happy

I have made 1.31.pet ( containing de also )

Code:
# ./pfilesearch -h

Yeh.
I have tried automatic conversion by next code against the locales file:
Code:
sed -e 's/\([^=\]\)"\([ ]*#.*$\)/\1")\2/'   -e 's/\([^=\]\)"[ ]*$/\1")/' -e 's/^\([A-Z][0-9A-Z_]*\)="/\1=$(gettext "/'  -e "s/\\([^=\\]\\)'\\([ ]*#.*\$\\)/\\1')\\2/" -e "s/\\([^=\\]\\)'[ ]*\$/\\1')/" -e "s/^\\([A-Z][0-9A-Z_]*\\)='/\\1=\$(gettext '/" $SOURCE > $DEST

Mostly it works. But some case, we need to modify the original...

I have tested it with SOURCE=/usr/local/pfilesearch/locales
Does convert half (just the trailing ) ) for
export ....
and more than 1 liners

Examples:
export LOC_NO="No")
LOC_QUIT=$(gettext "Quit")

Missing
'$(gettext '
can easily be inserted manually.
------

Converting also the existing translations would be great Question

Full automation is difficult. But it will hopefully be an useful tool.
Unzip the attached, add executable, place at /root/applications/bin or somewhere under the $PATH.

# locale2gettext --help
locale2gettext 0.1

usage: locale2gettext [PATH_TO_LOCALE_FILE] [TEXT_DOMAIN]

Yes it is helpful, has been running successfully for pfilesearch

I have tried to put the gettext into the script
(easier to understand and to maintain)
Does not work with multi line messages
But I got pfilesearch running with this:
Code:

#!/bin/sh

# replace variables by gettext expression
# example:
# LOC_OPTIONS=$(gettext "Options") # line in locales.converted
# line in script:
#     <frame $LOC_OPTIONS>
# will become:
#     <frame $(gettext "Options")>
#

input_file=locales.converted
# create sed file
conversion_file=locales.sed
delimiter='@' # not used in script ???
echo "#sed expressions for conversion of pfilesearch" >  $conversion_file
while read LINE; do
 case "$LINE" in
 \#*) continue                                                           # skip comments
      ;;
   *) [ -z "$LINE" ] && continue                                         # skip blank lines
      [ "`echo $LINE | grep '^export TEXTDOMAIN='`" ]     && continue    # skip
      [ "`echo $LINE | grep '^export OUTPUT_CHARSET='`" ] && continue    # skip
      [ "${LINE:0:7}" = "export " ] && LINE="${LINE//export }"           # delete 'export '
      LINE="${LINE//=\$\(/$delimiter\$(}"                                # s#FROM${delimiter}TO#
      [ "${LINE:0:3}" = "LOC" ] && LINE="s${delimiter}${LINE//\$}"       # s${delimiter}FROM#TO#
      [ "`echo $LINE | grep -E '\"\)$'`" ] && LINE="${LINE}${delimiter}" # s#FROM$#TO${delimiter}
      ;;
 esac
 echo $LINE >> $conversion_file
done < $input_file
echo finished $conversion_file

# delete multiliners
cat $conversion_file | grep -E "^s${delimiter}LOC" | grep -E "${delimiter}$"  > $conversion_file.1liners
echo finished $conversion_file.1liners

# replace $LOCxxx by gettext (....)
sed -f $conversion_file.1liners pfilesearch > pfilesearch.converted
echo finished pfilesearch.converted
chmod +x pfilesearch.converted

echo run converted script in console to see errors !
echo some errors can be fixed by escaping quotes !!
echo do not forget to the muliliners !!!


Feel free to add it (maybe change some variables) to your locale2gettext

I am going to convert pfind now. That is the most logical step after pfilesearch.

If we convert only the file 'locales' and do not change any of others, it allows backward compatibility, i mean we can use old NLS as is.

yeah, that is true.

But new apps should be coded without the LOCxx variables
It is easier to use just gettext inside the script.

But it is not a good idea...
The script takes the older NLS if there are both old and new.

Great!!!

Gettext has the advantage of making the code more readable (also for me Very Happy ). That is a good thing for the community. Converting the locales-file would sure be good for backward compatibility, but for moving the project further, I think updating the code itself is the way to go.

Smile
There is always something to learn and something to improve.

Generating po files from the old locals is also possible.
Code:
# LOC200
msgid "Filename"
msgstr "Имя файла"

# LOC203
msgid "Last modified"
msgstr "Изменен"

# LOC204
msgid "Permissions"
msgstr "Разрешения"

# LOC205
msgid "User"
msgstr "Пользователь"


Wait and see Cool

Subject description: Not tested well.		  
I have added gettext to pBurn but haven't tested it well yet. Just tested main GUI and have made partial Russian translation for testing. I haven't change set-language section of pburn script so translation only works if I choose or type in 'ru' language in Preferences.
I also didn't know what to do with line 398 of func_gui_options.
New MoManager finds all files and creates proper pot-file.
I didn't internationalize file func_man since it didn't have '$LOC' before...

Please test version 5.02

NLS has German (of course) and Russian (converted from old system)

So you can change between de, ru and English

Next I will try to convert the other languages.......

Hope you understand my solution in pfind ( used it in ymount some time ago Laughing ) Search for LANGUAGE NEW_LANGUAGE and LANGUAGES

Sorry I cannot help very much with testing because I do NOT have CD burner

OK, the first trial to place gettext inline the code.
But for multiple lines, i think we are better to stay the substitution method, that is:
Code:
export LOCXXX=$(gettext "First line
Second lne")
export DIALOG="<text><input>echo -n \"\$LOCXXX\"</inout></text>"


Extract the attached, add executable, place it at /root/my-applications/bin.
# zigbert2gettext --help
zigbert2gettext 0.1
Convert zigbert apps into gettext version.
usage: zigbert2gettext [PATH_TO_MAIN_SCRIPT] [TEXT_DOMAIN]
PATH_TO_MAIN_SCRIPT - example: /usr/local/pburn/pburn

But still you need to remove manually some code, loading the locales file, from the converted main script.
