Nimterlingua

Internationalization and localization at Compile Time for Nim.
1 Macro to replace strings in-place at compile time with 0 cost at runtime.
Translate unmodified code from 1 INI file. Replace Emojis and Unicode in-place.
High performance with low resources, everything is done compile-time only!.

Use

translations.cfg:

# This is a comment.
[cat]
ES_AR = gato
PT_BR = minino



[dog]
ES_AR = perro
PT_BR = cão

; You can replace Emojis. This is a comment.
[:crown:]
ES_AR = 👑
PT_BR = 👑

Nim:

import nimterlingua

nimterlingua()
echo "cat"
echo "dog"
echo ":crown:"

Compile:

nim c -r -d:ES_AR -d:iniFile="translations.cfg" yourfile.nim

nim c -r -d:PT_BR -d:iniFile="translations.cfg" yourfile.nim

NimScript:

import nimterlingua

nimterlingua()
echo "cat"
echo "dog"
echo ":crown:"

Run:

nim e -d:ES_AR -d:iniFile="translations.cfg" yourfile.nims

nim e -d:PT_BR -d:iniFile="translations.cfg" yourfile.nims

NodeJS:

import nimterlingua

nimterlingua()
echo "cat"
echo "dog"
echo ":crown:"

Compile:

nim js -d:nodejs -d:ES_AR -d:iniFile="translations.cfg" yourfile.nim

nim js -d:nodejs -d:PT_BR -d:iniFile="translations.cfg" yourfile.nim

bohemian_rhapsody.nim(22, 7) Hint: ES_AR7("Because I\'m easy come, easy go") --> '"Porque fácil vengo, fácil me voy"' [Pattern]
bohemian_rhapsody.nim(23, 7) Hint: ES_AR8("A little high, little low") --> '"Un poco alto, un poco bajo"' [Pattern]

Es la vida real?
Es sólo fantasía?
Atrapado en un derrumbe
Sin escape de la realidad
Abre tus ojos
Mira a los cielos y observa
Sólo soy un chico pobre, no necesito simpatía
Porque fácil vengo, fácil me voy
Un poco alto, un poco bajo
De todos modos el viento sopla, realmente no me importa, a mi
Mamá, maté a un hombre
Puse una pistola en su cabeza
Jalé el gatillo, ya está muerto
Si no regreso mañana a esta hora
Continúa, continúa, como si nada realmente importara

How does it works internally?.

Nimterlingua Vs GetText

Nimterlingua	GetText
No `*.po` files	You need to write `*.po` files
No `*.pot` files	You need to extract `*.pot` files
No `*.mo` files	You need to compile `*.mo` files
No `*.gmo` files	You need to compile `*.gmo` files
Only `nim`	`xgettext`, `msginit`, `msgfmt`, etc
Any editor, `*.INI` format	Requires `poedit` for fluent workflow
Unmodified code can be translated	Requires refactor adding gettext functions
`"cat"`	`gettext("cat")` or `_("cat")`
No GetText dependency	GetText libs as dependency
0 cost at runtime performance	Slows runtime performance (even on C)
`*.INI` is easy to delegate to people	`*.po` format complex for non-tech people
Chill Lazy Dev	Time consuming beyond translation itself

Beyond Translation

Its designed for translation, but it does not force anything on you, you can be creative and explore other possible uses.

It replaces in-place any arbitrary string with any arbitrary string you want at compile time with 0 cost at runtime without touching the code.

Let us know if you built something cool with it!.

FAQ

Its not possible to have different languages in 1 Nim program?.

Use a period (dot), exclamation, space, emoji or something, the string will not match anymore.

[cat]
ES_AR = gato

if useSpanish: "cat" else: "cat."

"cat" get translated to Spanish, "cat." remains English, because of period.

You choose languages with if or case or similar on your code.

Or use NimScript or NodeJS to get a JSON or CSV or similar format and get the data from there.

I get nimterlingua.nim(17, 29) Error: cannot open file: translations.cfg ?

compile with -d:iniFile="path to your translations.cfg"

Is there a Minimal Basic example?.

https://github.com/juancarlospaco/nim-nimterlingua/blob/master/example/minimal.nims

How do you use this with Python or NodeJS or JavaScript?.

https://github.com/juancarlospaco/nim-nimterlingua/blob/master/example/minimal.nims

This works with NodeJS and JavaScript?.

Yes.

My Translated text contains = will make it fail?.

Use splitter=":", then use it as splitter separator.

[cat]
ES_AR : gato

How to make an INI for a lot of languages?.

[cat]
ES_AR = gato
PT_BR = minino
RU    = kot
FR    = chat
# A lot of languages here...

This is not the same as Search&Replace of any Editor?.

No. Because it actually fully understands the code, typical Search&Replace of Editor can break comments, names, variables, etc.
