Core: The params for translations are ignored

[esavelyeva]

Current behavior

The params for translations are ignored.

Expected behavior

Params values should be added into the translation.

How do you think that we should fix this?

No idea.

For now I'm using this function to apply the prams to the translations:

export function applyParamsToTranslation(trans: string, params: Object): string {
  // TODO add err handling
  function getTransParamNames(text: string): Array<string> {
    return text.match(/{{\s*[\w\.]+\s*}}/g).map(function(bracedParam) {
      return bracedParam.match(/[\w\.]+/)[0];
    });
  }
  const keys = getTransParamNames(trans);
  for (let i = 0; i < keys.length; i++) {
    if (params[keys[i]]) {
      trans = trans.replace(keys[i], params[keys[i]]);
    }
  }
  return trans.replace(/{{|}}/g, '');
}
