RegexToolbox.Java

Regular expression tools for Java developers.

RegexBuilder

RegexBuilder is a class for building regular expressions in a more human-readable way using a fluent API. It offers a number of benefits over using raw regex syntax in strings:

• No knowledge of regular expression syntax is required: just use simple, intuitively-named classes and methods.
• Code is easier to read, understand and maintain.
• Code is safer and far less prone to regular expression syntax errors and programmer errors.

Here's an example:

Pattern regex = new RegexBuilder()
    .text("Hello")
    .whitespace(RegexQuantifier.oneOrMore())
    .text("world!")
    .buildRegex();

But that's just a taste of what RegexBuilder does: for full API documentation, head over to the project wiki.

Breaking change in 2.0: Logging removed

The logging API added in version 1.3 wasn't adding as much value as intended and incurred an additional maintenance overhead. It is removed in version 2.0.
