ngx-translate-check's Issues

Translations are not detected in *.ts files

Hello !

First, thanks a lot for your work, it allowed me to detect a ton of unused translations :)

I have quite a few translations that are handled directly in typescript files. As per the documentation (and some comments in the code), they should be detected, but they are not.

It comes from the parseFile method:

function parseFile(fileName) {
  const file = readFileSync(fileName, { encoding: 'utf8' });

  // May start with '{{' and end with '}}', but not necessary.
  // Internal string is separated by \' or \".
  // String is filled with multiple dot separated words.
  // After the string, whitespace with a pipe | separator.
  // After the operator, the translate pipe.
  // Ending the regex, whitespace and the optional '}}'.
  const matched = file.match(
    /({{)?( )*(\'|\")((\w|\-)\.?)*(\'|\")( )*\|( )*translate( )*(}})?/g
  );

  // Only return internal string of matches
  let foundStrings = [];
  if (matched && matched.length > 0) {
    foundStrings = matched.map(str => str.match(/(\'|\")(.*)?(\'|\")/)[2]);
  }
  return foundStrings;
}

The first and second regex are not compatible with following piece of code for example:

        private openErrorMessage(): void {
		const errorMessage: string = this.translateService.instant('ERROR_UNKNOWN');
		this.snackBar.open(errorMessage, null, { panelClass: 'error' });
	}

Another case where it doesn't work is when the translate pipe is on the next line in an html template.

Error when using diff and diff-input options

I was trying the project and I couldn't use. files option work without any problem but other options give errors
