[jboss-jira] [JBoss JIRA] Created: (JBRULES-2434) Emiting regexps in DSLs is unwieldy in the extreme

Emiting regexps in DSLs is unwieldy in the extreme -------------------------------------------------- Key: JBRULES-2434 URL: https://jira.jboss.org/jira/browse/JBRULES-2434 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler-DSL Affects Versions: 5.0.1.FINAL Environment: All Reporter: Denis Robert Assignee: Mark Proctor Priority: Minor Any regexp emitted by a DSL must be octupled in order to pass through to the DRL and actually work in the rule. Example: I have a simple rule (I should say: a rule which SHOULD be simple), to test for emails: [condition][]is not email=not matches "^[\\\\\\\\w-]+(\\\\\\\\.[\\\\\\\\w-]+)*@([a-z0-9-]+(\\\\\\\\.[a-z0-9-]+)*?\\\\\\\\.[a-z]{2,6}|(\\\\\\\\d{1,3}\\\\\\\\.){3}\\\\\\\\d{1,3})(:\\\\\\\\d{4})?$" As you can see, each backslash is there 8 times. By then time it appears in the resulting DSL, they are doubled (which contrary to docs must be the case, otherwise the regexp does not behave correctly). Regular expressions should be treated differently throughout Drools. Maybe by using raw strings as in Perl or C#? It's really annoying... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
