Daniel Barclay (Drill) created DRILL-3697:
---------------------------------------------
Summary: REGEXP_REPLACE doc. says POSIX reg. expr.; which? not
Java?
Key: DRILL-3697
URL: https://issues.apache.org/jira/browse/DRILL-3697
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
The {{REGEXP_REPLACE}} function documentation currently at
[https://drill.apache.org/docs/string-manipulation/#regexp_replace] says that
{{REGEXP_REPLACE}} uses POSIX regular expressions.
Is that true (that Drill using POSIX regular expressions and not Java regular
expressions)?
If that's really true, are they BREs or EREs?
Assuming it's actually Java regular expressions, the documentation should
probably have a link to some appropriate target in the JDK Java doc (maybe
http://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html and
http://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#replaceAll-java.lang.String-.
