Technical Architecture: Unicode Case Mapping & Lexical Casing Rules
Converting text case requires handling both standard typography conventions and developer naming conventions. Simple string methods like toUpperCase() and toLowerCase() fail to handle grammatical Title Case or programming case structures. Khalasna executes case transformations client-side using regular expression tokenization and Unicode-aware casing rules. For Title Case, the engine parses words, cross-referencing against an exception dictionary of minor stop words (articles like 'a', 'an', 'the'; prepositions like 'in', 'on', 'at'; coordinating conjunctions like 'and', 'but'), capitalizing them only when they appear as the first or last word of a sentence or title. For developer formats (camelCase, snake_case, kebab-case), the tokenizer strips non-alphanumeric separators, identifies word boundaries, and applies sequential capitalization or delimiter injection (underscores or hyphens). The entire pipeline executes locally with zero network delay.
