Create complex regular expression from tokens by Trie.
RegexpTrie trie = new RegexpTrie();
trie.add("foobar");
trie.add("fooxar");
trie.add("foozap");
trie.add("fooza");
System.out.println(trie.regexp());
// → (?:foo(?:bar|xar|zap?))
This module generates regular expression from list of tokens. It builds a trie-ized regexp as above.
You can only add plain strings into regular expression. You can't use meta characters in it. a+b is treated as a\+b, not "more than one a's followed by b".
This artifact is available on maven central. You need to add following snippet into your pom.xml.
