[Pas2js] resourcestrings structure

[warleyalex]

Basically i18next, looks for the attribute "data-i18n" and replaces the texts
in one go using DOM manipulations.

see in action:

https://pas2js.github.io/index.html

Yeash, so the experiment is basically
I'm trying to play with pas2js "resourcestrings" with the external lib
"i18next" to build multi-lingual using DOM Manipulating. 

The idea is to keep a series of "language" local JSON files separared, we
need to generate these files:
- en.jrs
- fr.jrs
- it.jrs
- br.jrs

Based on the units:
---------------------
unit en;

{$mode objfpc}

interface

resourcestring
  Good_bye = 'Good bye! $t(menu.country)';
  Hello =  'Hello! $t(menu.country)';
  Selectyourlanguage =  'Select your language: $t(menu.country)';
  country = 'England';

implementation

end.  
-----------------------
unit fr;

{$mode objfpc}

interface

resourcestring
  Good_bye = 'Au revoir ! $t(menu.country)';
  Hello =  'Bonjour ! $t(menu.country)';
  Selectyourlanguage =  'Sélectionner votre langage: $t(menu.country)';
  country = 'France';

implementation

end.
-----------------------
unit it;

{$mode objfpc}

interface

resourcestring
  Good_bye = 'Arrivederci! $t(menu.country)';
  Hello =  'Buongiorno! $t(menu.country)';
  Selectyourlanguage =  'Seleziona la tua lingua: $t(menu.country)';
  country = 'Italy';

implementation

end.
-----------------------
unit br;

{$mode objfpc}

interface

resourcestring
  Good_bye = 'Oi! $t(menu.country)';
  Hello =  'Olá! $t(menu.country)';
  Selectyourlanguage =  'Selecione seu idioma: $t(menu.country)';
  country = 'Brasil';

implementation

end.
*****************************
... so we've generated 4 files:

 pas2js -Jrunit en.pas -B
 pas2js -Jrunit fr.pas -B
 pas2js -Jrunit it.pas -B
 pas2js -Jrunit br.pas -B

**********************************
{
"it" : {
    "Good_bye" : "Arrivederci! $t(menu.country)",
    "Hello" : "Buongiorno! $t(menu.country)",
    "Selectyourlanguage" : "Seleziona la tua lingua: $t(menu.country)",
    "country" : "Italy"
  }
}
------
{
  "fr" : {
    "Good_bye" : "Au revoir ! $t(menu.country)",
    "Hello" : "Bonjour ! $t(menu.country)",
    "Selectyourlanguage" : "Sélectionner votre langage: $t(menu.country)",
    "country" : "France"
  }
}
-------
{
  "en" : {
    "Good_bye" : "Good bye! $t(menu.country)",
    "Hello" : "Hello! $t(menu.country)",
    "Selectyourlanguage" : "Select your language: $t(menu.country)",
    "country" : "England"
  }
}
------
{
  "br" : {
    "Good_bye" : "Oi! $t(menu.country)",
    "Hello" : "Olá! $t(menu.country)",
    "Selectyourlanguage" : "Selecione seu idioma: $t(menu.country)",
    "country" : "Brasil"
  }
}
------
*****
pas2js declares for each of the .jrs an object which is basically the
namespace "unit Name", following this structure:

{
  %unitName% : {
    %key% : %value%,
  }
}

However, we can not play i18next lib with pas2js/resourcestrings to perform
multi-lingual idea. 

it works as expected if we change manually all the 4 .jrs files and change
the object/namespace to have multi-lingual feature.

{ filename: en.jrs }

{
  "menu" : {
    "Good_bye" : "Good bye! $t(menu.country)",
    "Hello" : "Hello! $t(menu.country)",
    "Selectyourlanguage" : "Select your language: $t(menu.country)",
    "country" : "England"
  }
}

ahm, the command line to set manually the namespace, I think:

 pas2js -Jrunit en.pas -B -NS"menu" 
 pas2js -Jrunit fr.pas -B -NS"menu" 
 pas2js -Jrunit it.pas -B -NS"menu" 
 pas2js -Jrunit br.pas -B -NS"menu" 

Yeah, I agree: "the pas2js compiler creates the internal structure. You must
follow this structure when 
translating. How you get your translations, is entirely up to you."
