l10n-tag

tagged template based on es6. Inspired by i18n-tag.

Sample

res_en.json:

{
    "HELLO ${0}, ${1}.": "hello ${0}! the content is '${1}'."
}

main.js:

const l10nTag = require('l10n-tag');
const en = require('res_en.json');

const l10n = l10nTag(en);

let name = 'foo';
let content = 'test template string';

let message = l10n`HELLO ${name}, ${content}.`;

console.log(message); // "hello foo! the content is 'test template string'." will be output.

Options

options can be used when create l10n.

...
const l10n = l10nTag(en, options);

options.cb

options.cb is callback, it will be called if l10n cannot found key, default behavior is output error by debug.

const log = ...;
const l10n = l10nTag(en, {
	cb(key, inputs, values) {
		log.warn(`${key} was missing.`);
	}
});

options.cb can also return default message key.

const log = ...;
const l10n = l10nTag(en, {
	cb(key, inputs, values) {
		return 'some message';
	}
});

options.prefix, options.surffix

options.prefix and options.surffix can be used when need define prefix and surffix of template key, default value is ${ and }.

res2_en.json:

{
    "HELLO {0}, {1}.": "hello {0}! the content is '{1}'."
}

main.js:

const l10nTag = require('l10n-tag');
const en = require('res2_en.json');
const l10n = l10nTag(en, {prefix:'{', surfix:'}'});
