"""Generates the list of canonical language codes for base::LanguageCode.

This script generates a C++ include file (`.inc`) containing
`IMPL_LANGUAGECODE_TAG_NAME(tag, name)` macros for all supported language codes
in Chromium. The tag is the BCP47 language code and `name` is the all caps
name of the language. For example:

IMPL_LANGUAGECODE_TAG_NAME("en", ENGLISH)
IMPL_LANGUAGECODE_TAG_NAME("pt-BR", PORTUGUESE_BRAZIL)
IMPL_LANGUAGECODE_TAG_NAME("zh-Hans", CHINESE_SIMPLIFIED)

The script uses a hardcoded list of locales defined within it.

Usage:
  generate_canonical_locales_list.py <output_file>
    <output_file>: The path to the file to generate (usually in $root_gen_dir).

This script is run by the `canonical_language_codes_gen` action in
`base/i18n/internal/BUILD.gn`. The generated file is included in
`base/i18n/internal/language_code_builder.h` and `base/i18n/language_codes.h`.
