vilicvane / lexer.ts
Last active February 19, 2020 09:58
A lexer (behave like Angular expression lexer) written with the help of regular expression.
/**
* A test using regular expression for lexing
* by vilicvane<https://vilic.github.io/>
*
* It turns out to be 50% faster comparing to original Angular lexer before JIT Compilation, but 50% slower then (in Chrome).
* And only 1/3 of the original lexer counting the core code lines.
* Though it's because the regular expressions are doing most of the work.
*
* Note: The regular expression and related enum declaration are managed by https://github.com/vilic/regex-tools/.
