pt_BR should work now
If you first translate just some messages for pt (not all)
then these should be preloaded when starting pt_BR

If you do this then pt is killed.
Change script t12s line 234 from
mv ${T}/${x}/${app} ${T}/${this_LANG}/${app}_tmp
to
cp ${T}/${x}/${app} ${T}/${this_LANG}/${app}_tmp

That is: copy instead of move and pt will continue to live
And soon you will become a coder too Very Happy

Done. Here are the results:

Arrow Tested t12s with mentioned line modified.
Arrow Translation was generated properly with no more question marks where special characters should be, for example 'n?o' instead of 'não'.
Exclamation The adding of a new translated line caused the whole list of translatable lines to repeat below, making the list longer than it actually is.
Exclamation At times I submitted a translation and then saw the line blank where the new translation should be, I had to Undo, Quit and start the script again to be able to submit the translation. Finally, as the bug continued, I had to edit the generated locale file to manually complete the translation process.

Generated translations:

Code:

_M_10="AJUDA"
_M_11="Arquivo novo:"
_M_12="Arquivo novo ou .delta:"
_M_13="Arquivo velho:"
_M_14="por favor espere..."
_M_15="Por favor espere, procurando arquivo velho..."
_M_16="Desculpe não achous-se ${OLDFILENAME}. Terá de arrastá-lo manualmente na caixa ´Arquivo velho´"
_M_17="SUCESSO! ${SOURCEFILE_DELTA} gerado"
_M_18="SUCESSO! ${SOURCEFILE_NEW} gerado"
_M_19="O autor do Xdelta é Joshua MacDonald."
_M_20="Primeiro deve-se instalar o pacote ´xdelta´"
_M_21="Interface escrita por Barry Kauler. Licença GPL v2."
_M_22="O algoritmo Rsync, que inspirou o algoritmo delta central, deve-se a Andrew Tridgell e Paul Mackerras."
_M_23="Istas mudanças (deltas) são similares à saida do programa ´diff´ em que podem-se utilizar para armazenar e transmitir somente as mudanças entre arquivos. Porém, ao contrário do diff, a saida do Xdelta não é expressada em um formato legível pelos humanos (além disso Xdelta pode aplicar estes deltas a uma copia do arquivo original). Xdelta utiliza um rápido algoritmo linear e desenvolve-se bem tanto em arquivos binários quanto em arquivos de texto."
_M_24="Para criar um arquivo ´.delta´, você precisa dois arquivos originais, um arquivo ´velho´ e um ´novo´. O arquivo delta gerado terá uma extensão ´.delta´."
_M_25="Para gerar um arquivo ´.delta´, arraste os arquivos velho e novo aqui, ou para recriar o arquivo novo arraste os arquivos velho e ´.delta´ aqui"
_M_26="Bemvindo/a, ista é uma interface para a ferramenta ´xdelta´, para administrar mudanças entre dois arquivos"
_M_27="Xdelta é um programa de aplicação desenhado para computar mudanças entre dois arquivos."
_M_28="Você pode recriar o arquivo ´novo´ original, enquanto você tenha o arquivo ´velho´ original e o arquivo ´.delta´. Este frontend de interface faz com que isto seja fácil: somente arraste o arquivo .delta na caixa, e o programa procurará e localizará o arquivo velho original. Ou, somente clique em um arquivo .delta em uma janela do ROX-Filer para re-gerar o arquivo novo original."
_M_3="Erro, ´Arquivo novo´ não existe"
_M_4="Erro, ´Arquivo velho´ não existe"
_M_5="ERRO! falhiu a geração do arquivo .delta. Mensagem de erro:"
_M_6="ERRO! falhiu a recriação do arquivo novo. Mensagem de erro:"

Hi L18L

First, great job Smile

I have 3 queries before I embark on my first attempt. (later, answered myself, app link at bottom of post Smile )

1) Does this method handle strings with a newline char? ( \n )

example:
Code:
echo -en "Choices \n1. Firefox \n2. Seamonkey \n\nChoose 1 or 2 to download \n"


A: Yes

2) Can we use escaped quotes?

example:
Code:
echo "get_mozilla_browser-0.1
Invoke with \"get_mozilla_browser\" and you are offered a choice of
\"firefox\" or \"seamonkey\" latest stable browsers direct from mozilla
in your default locale if it exists.(snip)"


A: Yes

3) Can we use variables inside a string?

example:
Code:
echo "$PACKAGE en-US will be downloaded "


A; No
-

If the answer to any or all of these is "no" it isn't a problem as I can split up the strings.

TIA

EDIT: app here!

This time around the t12s script worked nicely Very Happy
I've even been able to change language so that I can make a new locale for the same file just after I finished the one I've worked on previously. However, I had to check that the locale folders were in place -- as the 'locales' folder was empty, I had to create individual folders for the locales I usually make (es, pt_BR, it, fr) so that the translations were generated there. If there wasn't a folder for the locale I wanted to work with, upon selecting the script to translate I got an empty list with no lines to translate, so I quit, created the locale folders and started t12s again, then I just wrote the folder name (es, it, fr, etc.) and got the list of translatable lines.
I think I'm ready to learn how to make the scripts translatable myself Very Happy . Who knows, maybe I can make a localized pupplet, something like 'Wary EPI (= Español-Português-Italiano, the languages with less pupplets available that are based on newer puppy versions)'

Hi 01micko,

thanks for answering the first two questions yourself Smile

Splitting strings is Evil or Very Mad
RTFineM
Enabling translation of entire sentences, that is the purpose of eval_gettext.
The equivalent in t12s method is (your example):

Code:
[ -f $LOCALES ] && . $LOCALES
echo ${_M_:-$PACKAGE en-US will be downloaded }


A: Yes Very Happy

The last two days I was trying this method on playmusic:
nice experience, bugfixes

I will have to update the documentation (BTW did you klick the button ´Developer´ ?)
{VAR} is no more required, see your PACKAGE example.

I will have a look into your app tomorrow.

Cheers

Sorry, but I cannot reproduce this. When I choose ar (Arabic, just an example Smile ) then immediately the folder ar is automatically made in /usr/share/locales

Please don't misunderstand, I didn't use the t12s prog, I did it manually.

I realise my syntax is wrong, which I'll fix and then try t12s.

Cheers

OK, I did misunderstand Embarassed

Start script t12s from command line line please.

The idea for this script was coming from practical use of the method:
Making IDs manually is ...
Repeated message (ex: please wait...) can be overseen
Numeric ID are shortest
The problem was to display the messages (including $...) in yad.
Every new app had new requirements to improve the code.

@ferro10n,
Maybe starting from command line can solve your problem?

@01micko,
your ´Browser Installer2´ appears to be a nice little app for demonstration. I would like to take screenshots from it and put them into my docu of t12s Smile
apps I have converted to t12s
askpass
alsawizard
xdelta_gui
playmusic
None of these is good for public understanding (I will have to review them checking syntax...) but´Browser Installer2´ is an app everybody will understand.

Cool

By all means. I deliberately kept it as simple as possible, partly with this in mind.

Later, (in a week maybe) I'll have some more time to help, give feedback, dive in, etcetera. Your t12s has great potential I think.

Subject description: new version of t12s		  
Having played with some of 01micko´s scripts it is time for a new version 0.4.5 of t12s now.

You may use now single quotes and double quotes inside messages
There is no more need to change them to apostrophes.

Using brackets [ ] you must have space after [ and before ]

Have fun
