Character Parser for Template Snippets

`character-parser` is a focused JavaScript utility library designed for parsing JavaScript code snippets, particularly within template languages like EJS or Jade. Its primary function is to robustly handle bracket nesting, strings, and comments, allowing for the reliable extraction of delimited JavaScript sections without performing a full syntax validation or abstract syntax tree (AST) generation. The current stable version is 4.0.0, which introduced significant changes including native ES module support and updated package export configurations. This library differentiates itself by offering a lightweight, character-by-character parsing mechanism and state management, providing functions to parse entire strings or single characters, track nesting depth, and find code segments based on custom delimiters while intelligently ignoring content within nested structures or comments. It does not aim to be a comprehensive JavaScript parser but rather a precise tool for template-driven code extraction.
