Namespace leex/yecc modules to localize_* to coexist with ex_cldr

[jerryluk]

Problem

localize's grammar modules were extracted from ex_cldr with their module names intact — rbnf_parser, rbnf_lexer, plural_rules_parser, plural_rules_lexer, decimal_formats_parser, decimal_formats_lexer, date_time_format_lexer. An application that depends on both localize (e.g. via ex_money >= 6) and ex_cldr/ex_cldr_numbers (still common for Cldr.Number, territories, locale display) cannot assemble a release:

** (Mix) Duplicated modules:
	rbnf_parser specified in ex_cldr_numbers and localize
	rbnf_lexer specified in ex_cldr_numbers and localize
	plural_rules_parser specified in ex_cldr and localize
	plural_rules_lexer specified in ex_cldr and localize
	decimal_formats_parser specified in ex_cldr_numbers and localize
	decimal_formats_lexer specified in ex_cldr_numbers and localize

This is invisible in dev/test (the BEAM just loads one of them) and only surfaces at mix release, so it tends to be discovered late, in deploy pipelines.

Change

Mechanical rename of the src/ grammar files to a localize_ prefix (module name = filename for leex/yecc) plus the 12 internal call sites and one test assertion that pattern-matches the yecc error tuple. The full suite passes unchanged (27,910 tests).

Happy to adjust naming if you'd prefer a different prefix. Found while upgrading ex_money 5→6 in an app that keeps ex_cldr for its own formatting.

Thanks very much @jerryluk, you're right - I should have changed these module names but because they are in Erlang-land I missed them during the sweep. And yes, now some divergence - particularly in rbnf_lexer to improve compilation performance (a lot!) and rbnf_parser (to fix bugs).

I'll get a new release out by the end of the weekend.

I've published localize version 0.49.0 with the following changelog entry:

[0.49.0] — July 12th, 2026

Fixed

• Change the namespaces on the leex lexers and yecc parsers to avoid module name clash with ex_cldr versions. Thanks to @jerryluk for the PR. Closes Namespace leex/yecc modules to localize_* to coexist with ex_cldr #40.

• The coverage ignore list follows the renamed lexer/parser modules, restoring measured coverage above the 90% CI threshold; a guard test now fails when an ignore-list entry names a module that no longer exists.

Thanks again for the PR.
