FAQ

Questions ICU MessageFormat Validator owners ask.

  • 01

    How does the validator handle single quotes?

    The validate_structural_braces capability implements a state machine to track escaping. It recognizes that two consecutive single quotes (double-single-quote) represent a literal single quote, preventing the parser from incorrectly terminating an escaped sequence.

  • 02

    What happens if I use an invalid category in a plural block?

    If you include an unsupported keyword like 'none' or 'all', the validate_category_logic capability will flag a syntax error, identifying the exact character offset where the invalid category was detected.

  • 03

    Can I use this to find all variables in my translation files?

    Yes, by using the extract_template_variables capability, you can provide any ICU string and receive a complete list of all unique variable names found within the template, such as 'userName' or 'itemCount'.
