[jira] [Commented] (CAY-2130) Stripping common name prefixes on reverse engineering

["Andrus Adamchik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAY-2130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15626181#comment-15626181 ] 

Andrus Adamchik commented on CAY-2130:
--------------------------------------

"sed syntax" may not be clear to some Java devs, and the need to use a third-party parser is less than ideal. Actually I think we can make it simpler. Instead of a full sed script, we might use a simple regex that matches the part that needs to be stripped off:

{noformat}
<stripFromTableNames>^myt_</stripFromTableNames>
{noformat}

> Often table namespacing in a database is done by prepending a common prefix to table names. Would be nice to be able to clean up the names before we make java names for them. E.g. transform "myt_table1" into "Table1", "XyzTable1" also into "Table1". Looks like what we need is a sed-like expression. E.g. in maven config form:
> {noformat}
> <tableNameFilter>s/^myt_//i</tableNameFilter>
> {noformat}
> The problem is that Java Pattern can't directly parse such expressions. May need to use  a third-party library like https://github.com/tools4j/unix4j or similar.
