ECMAScript compatible RegExp library for Java

Using as a Maven dependency

<dependency>

    <artifactId>regexp4j</artifactId>
    <version>0.1.0</version>

Limitations

• Matching is performed by code point, not by code unit as in ECMAScript. For example, metacharacter . may match a character in supplementary planes encoded as a surrogate pair.
• Regular expression . does not match a next-line character U+0085, which is categorized as a line terminator in Java.
• Forward references are not supported.
• Group values never be overwritten by null in looping by quantifiers.
• The lower and upper bounds in bounded quantifier {m}, {m,}, and {m, n} cannot be greater than Integer.MAX_VALUE.
• Unicode flag u is not implemented yet.
