# Bilioteca de internacionalización para Minetest
|
||||
|
||||
Por Diego Martínez (kaeza).
|
||||
Lanzada bajo Unlicense. Véase `LICENSE.md` para más detalles.
|
||||
|
||||
Éste mod es un intento por proveer soporte para internacionalización
|
||||
de los mods (algo que a Minetest le falta de momento).
|
||||
|
||||
Si tienes alguna duda/comentario, por favor publica en el
|
||||
[tema del foro][topic]. Por reporte de errores, use el
|
||||
[bugtracker][bugtracker] en Github.
|
||||
|
||||
## Cómo usar
|
||||
|
||||
Si eres un jugador regular en busca de textos traducidos, simplemente
|
||||
[instala][installing_mods] éste mod como cualquier otro.
|
||||
|
||||
El mod trata de detectar tu idioma, pero ya que no hay una forma portable de
|
||||
hacerlo, prueba varias alternativas:
|
||||
|
||||
* `language` setting in `minetest.conf`.
|
||||
* `LANGUAGE` environment variable.
|
||||
* `LANG` environment variable.
|
||||
|
||||
En cualquier caso, el resultado final debería ser el
|
||||
[Código de idioma ISO 639-1][ISO639-1] del idioma deseado.
|
||||
|
||||

# Biblioteca de Internacionalización para Minetest
|
||||
|
||||
Por Diego Martínez (kaeza).
|
||||
Lanzada bajo WTFPL.
|
||||
|
||||
Éste mod es un intento de proveer soporte para internacionalización para otros mods
|
||||
(lo cual Minetest carece actualmente).
|
||||
|
||||
## Cómo usar
|
||||
|
||||
### Para usuarios finales
|
||||
|
||||
Para usar éste mod, simplemente [instálalo](http://wiki.minetest.net/Installing_Mods)
|
||||
y habilítalo en la interfaz.
|
||||
|
||||
Éste mod intenta detectar el idioma del usuario, pero ya que no existe una solución
|
||||
portable para hacerlo, éste intenta varias alternativas, y utiliza la primera
|
||||
encontrada:
|
||||
|
||||
* Opción `language` en `minetest.conf`.
|
||||
* Si ésta no está definida, usa la variable de entorno `LANG` (ésta está
|
||||
siempre definida en SOs como Unix).
|
||||
* Si todo falla, usa `en` (lo cual básicamente significa textos sin traducir).
|
||||
|
||||
En todo caso, el resultado final debe ser el In any case, the end result should be the
|
||||
[Código de Idioma ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
del idioma deseado. Tenga en cuenta tambien que (de momento) solo los dos primeros
|
||||
caracteres son usados, así que por ejemplo, las opciones `de_DE.UTF-8`, `de_DE`,
|
||||
y `de` son iguales.
|
||||
|
||||
Algunos códigos comúnes: `es` para Español, `pt` para Portugués, `fr` para Francés,
|
||||
`it` para Italiano, `de` para Aleman.
|
||||
|
||||
### Para desarrolladores
|
||||
|
||||
Para habilitar funcionalidad en tu mod, copia el siguiente fragmento de código y pégalo
|
||||
al comienzo de tus archivos fuente:
|
||||
|
||||
```lua
|
||||
-- Boilerplate to support localized strings if intllib mod is installed.
|
||||
local S
|
||||
if minetest.get_modpath("intllib") then
|
||||
S = intllib.Getter()
|
||||
else
|
||||
-- Si no requieres patrones de reemplazo (@1, @2, etc) usa ésto:
|
||||
S = function(s) return s end
|
||||
|
||||
-- Si requieres patrones de reemplazo, pero no escapes, usa ésto:
|
||||
S = function(s,a,...)a={a,...}return s:gsub("@(%d+)",function(n)return a[tonumber(n)]end)end
|
||||
|
||||
-- Usa ésto si necesitas funcionalidad completa:
|
||||
S = function(s,a,...)if a==nil then return s end a={a,...}return s:gsub("(@?)@(%(?)(%d+)(%)?)",function(e,o,n,c)if e==""then return a[tonumber(n)]..(o==""and c or"")else return"@"..o..n..c end end) end
|
||||
end
|
||||
```
|
||||
|
||||
Tambien necesitarás depender opcionalmente de intllib. Para hacerlo, añade `intllib?`
|
||||
a tu archivo `depends.txt`. Ten en cuenta tambien que si intllib no está instalado,
|
||||
la función `S` es definida para regresar la cadena sin cambios. Ésto se hace para
|
||||
evitar la necesidad de llenar tu código con montones de `if`s (o similar) para verificar
|
||||
que la biblioteca está instalada.
|
||||
|
||||
Luego, para cada cadena de texto a traducir en tu código, usa la función `S`
|
||||
(definida en el fragmento de arriba) para regresar la cadena traducida. Por ejemplo:
|
||||
|
||||
```lua
|
||||
minetest.register_node("mimod:minodo", {
|
||||
-- Cadena simple:
|
||||
description = S("My Fabulous Node"),
|
||||
-- Cadena con patrones de reemplazo:
|
||||
description = S("@1 Car", "Blue"),
|
||||
-- ...
|
||||
})
|
||||
```
|
||||
|
||||
Nota: Las cadenas en el código fuente por lo general deben estar en ingles ya que
|
||||
es el idioma que más se habla. Es perfectamente posible especificar las cadenas
|
||||
fuente en español y proveer una traducción al ingles, pero no se recomienda.
|
||||
|
||||
Luego, crea un directorio llamado `locale` dentro del directorio de tu mod, y crea
|
||||
un archivo "plantilla" (llamado `template.txt` por lo general) con todas las cadenas
|
||||
a traducir (ver *Formato de archivo de traducciones* más abajo). Los traductores
|
||||
traducirán las cadenas en éste archivo para agregar idiomas a tu mod.
|
||||
|
||||
### Para traductores
|
||||
|
||||
Para traducir un mod que tenga soporte para intllib al idioma deseado, copia el
|
||||
archivo `locale/template.txt` a `locale/IDIOMA.txt` (donde `IDIOMA` es el
|
||||
[Código de Idioma ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
de tu idioma (`es` para español).
|
||||
|
||||
Abre el archivo en tu editor favorito, y traduce cada línea colocando el texto
|
||||
traducido luego del signo de igualdad.
|
||||
|
||||
Ver *Formato de archivo de traducciones* más abajo.
|
||||
|
||||
## Formato de archivo de traducciones
|
||||
|
||||
He aquí un ejemplo de archivo de idioma para el español (`es.txt`):
|
||||
|
||||
```cfg
|
||||
# Un comentario.
|
||||
# Otro comentario.
|
||||
Ésta línea es ignorada porque no tiene un signo de igualdad.
|
||||
Hello, World! = Hola, Mundo!
|
||||
String with\nnewlines = Cadena con\nsaltos de linea
|
||||
String with an \= equals sign = Cadena con un signo de \= igualdad
|
||||
```
|
||||
|
||||
Archivos de idioma (o traducción) son archivos de texto sin formato que consisten de
|
||||
líneas con el formato `texto fuente = texto traducido`. El archivo debe ubicarse en el
|
||||
subdirectorio `locale` del mod, y su nombre debe ser las dos letras del
|
||||
[Código de Idioma ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
del lenguaje al cual se desea traducir.
|
||||
|
||||
Los archivos deben usar la codificación UTF-8.
|
||||
|
||||
Las líneas que comienzan en el símbolo numeral (`#`) son comentarios y son ignoradas
|
||||
por el lector. Tenga en cuenta que los comentarios terminan al final de la línea;
|
||||
no hay soporte para comentarios multilínea. Las líneas que no contengan un signo
|
||||
de igualdad (`=`) tambien son ignoradas.
|
||||
|
||||
## Palabras finales
|
||||
|
||||
Gracias por leer hasta aquí.

# Internationalization Lib for Minetest
|
||||
|
||||
By Diego Martínez (kaeza).
|
||||
Released as WTFPL.
|
||||
Released under Unlicense. See `LICENSE.md` for details.
|
||||
|
||||
This mod is an attempt at providing internationalization support for mods
|
||||
(something Minetest currently lacks).
|
||||
|
||||
## How to use
|
||||
|
||||
### For end users
|
||||
|
||||
To use this mod, just [install it](http://wiki.minetest.net/Installing_Mods)
|
||||
and enable it in the GUI.
|
||||
|
||||
The mod tries to detect the user's language, but since there's currently no
|
||||
portable way to do this, it tries several alternatives, and uses the first one
|
||||
found:
|
||||
|
||||
* `language` setting in `minetest.conf`.
|
||||
* If that's not set, it uses the `LANG` environment variable (this is
|
||||
always set on Unix-like OSes).
|
||||
* If all else fails, uses `en` (which basically means untranslated strings).
|
||||
|
||||
In any case, the end result should be the
|
||||
[ISO 639-1 Language Code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
of the desired language. Also note that (currently) only up to the first two
|
||||
characters are used, so for example, the settings `de_DE.UTF-8`, `de_DE`,
|
||||
and `de` are all equal.
|
||||
|
||||
Some common codes are `es` for Spanish, `pt` for Portuguese, `fr` for French,
|
||||
`it` for Italian, `de` for German.
|
||||
|
||||
### For mod developers
|
||||
|
||||
In order to enable it for your mod, copy the following code snippet and paste
|
||||
it at the beginning of your source file(s):
|
||||
|
||||
```lua
|
||||
-- Boilerplate to support localized strings if intllib mod is installed.
|
||||
local S
|
||||
if minetest.get_modpath("intllib") then
|
||||
S = intllib.Getter()
|
||||
else
|
||||
-- If you don't use insertions (@1, @2, etc) you can use this:
|
||||
S = function(s) return s end
|
||||
|
||||
-- If you use insertions, but not insertion escapes this will work:
|
||||
S = function(s,a,...)a={a,...}return s:gsub("@(%d+)",function(n)return a[tonumber(n)]end)end
|
||||
|
||||
-- Use this if you require full functionality
|
||||
S = function(s,a,...)if a==nil then return s end a={a,...}return s:gsub("(@?)@(%(?)(%d+)(%)?)",function(e,o,n,c)if e==""then return a[tonumber(n)]..(o==""and c or"")else return"@"..o..n..c end end) end
|
||||
end
|
||||
```
|
||||
|
||||
You will also need to optionally depend on intllib, to do so add `intllib?` to
|
||||
an empty line in your `depends.txt`. Also note that if intllib is not installed,
|
||||
the `S` function is defined so it returns the string unchanged. This is done
|
||||
so you don't have to sprinkle tons of `if`s (or similar constructs) to check
|
||||
if the lib is actually installed.
|
||||
|
||||
Next, for each translatable string in your sources, use the `S` function
|
||||
(defined in the snippet) to return the translated string. For example:
|
||||
|
||||
```lua
|
||||
minetest.register_node("mymod:mynode", {
|
||||
-- Simple string:
|
||||
description = S("My Fabulous Node"),
|
||||
-- String with insertions:
|
||||
description = S("@1 Car", "Blue"),
|
||||
-- ...
|
||||
})
|
||||
```
|
||||
|
||||
Then, you create a `locale` directory inside your mod directory, and create
|
||||
a "template" file (by convention, named `template.txt`) with all the
|
||||
translatable strings (see *Locale file format* below). Translators will
|
||||
translate the strings in this file to add languages to your mod.
|
||||
|
||||
### For translators
|
||||
|
||||
To translate an intllib-supporting mod to your desired language, copy the
|
||||
`locale/template.txt` file to `locale/LANGUAGE.txt` (where `LANGUAGE` is the
|
||||
[ISO 639-1 Language Code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
of your language.
|
||||
|
||||
Open up the new file in your favorite editor, and translate each line putting
|
||||
the translated text after the equals sign.
|
||||
|
||||
See *Locale file format* below for more information about the file format.
|
||||
|
||||
## Locale file format
|
||||
|
||||
Here's an example for a Spanish locale file (`es.txt`):
|
||||
|
||||
```cfg
|
||||
# A comment.
|
||||
# Another comment.
|
||||
This line is ignored since it has no equals sign.
|
||||
Hello, World! = Hola, Mundo!
|
||||
String with\nnewlines = Cadena con\nsaltos de linea
|
||||
String with an \= equals sign = Cadena con un signo de \= igualdad
|
||||
```
|
||||
|
||||
Locale (or translation) files are plain text files consisting of lines of the
|
||||
form `source text = translated text`. The file must reside in the mod's `locale`
|
||||
subdirectory, and must be named after the two-letter
|
||||
[ISO 639-1 Language Code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
|
||||
of the language you want to support.
|
||||
|
||||
The translation files should use the UTF-8 encoding.
|
||||
|
||||
Lines beginning with a pound sign are comments and are effectively ignored
|
||||
by the reader. Note that comments only span until the end of the line;
|
||||
there's no support for multiline comments. Lines without an equals sign are
|
||||
also ignored.
|
||||
|
||||
Characters that are considered "special" can be "escaped" so they are taken
|
||||
literally. There are also several escape sequences that can be used:
|
||||
|
||||
* Any of `#`, `=` can be escaped to take them literally. The `\#`
|
||||
sequence is useful if your source text begins with `#`.
|
||||
* The common escape sequences `\n` and `\t`, meaning newline and
|
||||
horizontal tab respectively.
|
||||
* The special `\s` escape sequence represents the space character. It
|
||||
is mainly useful to add leading or trailing spaces to source or
|
||||
translated texts, as these spaces would be removed otherwise.
|
||||
|
||||
## Final words
|
||||
|
||||
Thanks for reading up to this point.
|
||||
Should you have any comments/suggestions, please post them in the
|
||||
[forum topic](https://forum.minetest.net/viewtopic.php?id=4929). For bug
|
||||
reports, use the [bug tracker](https://github.com/minetest-mods/intllib/issues/new)
|
||||
[forum topic][topic]. For bug reports, use the [bug tracker][bugtracker]
|
||||
on Github.
|
||||
|
||||
Let there be translated texts! :P
|
||||
## How to use
|
||||
|
||||
\--
|
||||
If you are a regular player looking for translated texts, just
|
||||
[install][installing_mods] this mod like any other one, then enable it
|
||||
in the GUI.
|
||||
|
||||
Yours Truly,
|
||||
Kaeza
|
||||
The mod tries to detect your language, but since there's currently no
|
||||
portable way to do this, it tries several alternatives:
|
||||
|
||||
* `language` setting in `minetest.conf`.
|
||||
* `LANGUAGE` environment variable.
|
||||
* `LANG` environment variable.
|
||||
* If all else fails, uses `en`.
|
||||
|
||||
In any case, the end result should be the [ISO 639-1 Language Code][ISO639-1]
|
||||
of the desired language.
|
||||

# Intllib developer documentation
|
||||
|
||||
In order to enable it for your mod, copy some boilerplate into your
|
||||
source file(s). What you need depends on what you want to support.
|
||||
|
||||
There are now two main interfaces: one using the old plain text file method,
|
||||
and one using the new support for [gettext][gettext] message catalogs (`.mo`).
|
||||
Read below for details on each one.
|
||||
|
||||
You will also need to optionally depend on intllib, to do so add `intllib?`
|
||||
to an empty line in your `depends.txt`. Also note that if intllib is not
|
||||
installed, the getter functions are defined so they return the string
|
||||
unchanged. This is done so you don't have to sprinkle tons of `if`s (or
|
||||
similar constructs) to check if the lib is actually installed.
|
||||
|
||||
## New interface
|
||||
|
||||
You will need to copy the file `lib/intllib.lua` into the root directory of
|
||||
your mod, then include this boilerplate code in files needing localization:
|
||||
|
||||
-- Load support for intllib.
|
||||
local MP = minetest.get_modpath(minetest.get_current_modname())
|
||||
local S, NS = dofile(MP.."/intllib.lua")
|
||||
|
||||
Use the usual gettext tools (`xgettext`, `msgfmt`, etc.), to generate your
|
||||
catalog files in a directory named `locale`.
|
||||
|
||||
Note: Drop the `.mo` file directly as `locale/$lang.mo`. **Not** in
|
||||
`locale/$lang/LC_MESSAGES/$domain.mo`!
|
||||
|
||||
You should also provide the source `.po` and `.pot` files.
|
||||
|
||||
### Basic workflow
|
||||
|
||||
This is the basic workflow for working with [gettext][gettext]
|
||||
|
||||
Each time you have new strings to be translated, you should do the following:
|
||||
|
||||
cd /path/to/mod
|
||||
/path/to/intllib/tools/xgettext.sh file1.lua file2.lua ...
|
||||
|
||||
The script will create a directory named `locale` if it doesn't exist yet,
|
||||
and will generate the file `template.pot`. If you already have translations,
|
||||
the script will proceed to update all of them with the new strings.
|
||||
|
||||
The script passes some options to the real `xgettext` that should be enough
|
||||
for most cases. You may specify other options if desired:
|
||||
|
||||
xgettext.sh -o file.pot --keyword=blargh:4,5 a.lua b.lua ...
|
||||
|
||||
NOTE: There's also a Windows batch file `xgettext.bat` for Windows users,
|
||||
but you will need to install the gettext command line tools separately. See
|
||||
the top of the file for configuration.
|
||||
|
||||
Once a translator submits an updated translation, you should run the `msgfmt`
|
||||
tool:
|
||||
|
||||
msgfmt locale/ll_CC.po -o locale/ll_CC.mo
|
||||
|
||||
## Old interface
|
||||
|
||||
You will need this boilerplate code:
|
||||
|
||||
-- Boilerplate to support localized strings if intllib mod is installed.
|
||||
local S
|
||||
if minetest.get_modpath("intllib") then
|
||||
S = intllib.Getter()
|
||||
else
|
||||
-- If you don't use insertions (@1, @2, etc) you can use this:
|
||||
S = function(s) return s end
|
||||
|
||||
-- If you use insertions, but not insertion escapes this will work:
|
||||
S = function(s,a,...)a={a,...}return s:gsub("@(%d+)",function(n)return a[tonumber(n)]end)end
|
||||
|
||||
-- Use this if you require full functionality
|
||||
S = function(s,a,...)if a==nil then return s end a={a,...}return s:gsub("(@?)@(%(?)(%d+)(%)?)",function(e,o,n,c)if e==""then return a[tonumber(n)]..(o==""and c or"")else return"@"..o..n..c end end) end
|
||||
end
|
||||
|
||||
Next, for each translatable string in your sources, use the `S` function
|
||||
(defined in the snippet) to return the translated string. For example:
|
||||
|
||||
minetest.register_node("mymod:mynode", {
|
||||
-- Simple string:
|
||||
description = S("My Fabulous Node"),
|
||||
-- String with insertions:
|
||||
description = S("@1 Car", "Blue"),
|
||||
-- ...
|
||||
})
|
||||
|
||||
Then, you create a `locale` directory inside your mod directory, and create
|
||||
a "template" file (by convention, named `template.txt`) with all the
|
||||
translatable strings (see *Locale file format* below). Translators will
|
||||
translate the strings in this file to add languages to your mod.

# Intllib translator documentation
|
||||
|
||||
#### New interface
|
||||
|
||||
Use your favorite tools to edit the `.po` files.
|
||||
|
||||
#### Old interface
|
||||
|
||||
To translate an intllib-supporting mod to your desired language, copy the
|
||||
`locale/template.txt` file to `locale/LANGUAGE.txt` (where `LANGUAGE` is the
|
||||
[ISO 639-1 Language Code][ISO639-1] of your language.
|
||||
|
||||
Open up the new file in your favorite editor, and translate each line putting
|
||||
the translated text after the equals sign.
|
||||
|
||||
See `localefile.md` for more information about the file format.
