[jboss-jira] [JBoss JIRA] (WFCORE-1469) Support match-comparison operation for if-command

[ https://issues.jboss.org/browse/WFCORE-1469?page=com.atlassian.jira.plugi... ] Thomas Darimont updated WFCORE-1469: ------------------------------------ Description: Conditional expressions are great help for creating generic wildfly configurations with the CLI. Currently the {{comparison-operations}} for the {{if-expression}} are limited to - equal (==) - not equal (!=) - lesser than (<) - not lesser than (>=) - greater than (>) - not greater than (<=) I'd propose an additional comparison operation: a regex based match operation with the symbol {{~=}} wheras the left operand is a string to match against the right operand which is a regex string. This would enable a simple way to do feature flag detection via partial regex matches. The following sequence demonstrates this use case: {code} -Dfeatures="activemq jgroups" {code} {code} if (result ~= ".*activemq.*") of /:resolve-expression(expression=${features}) echo configuring activemq end-if if (result ~= ".*jgroups.*") of /:resolve-expression(expression=${features}) echo configuring jgroups end-if if (result ~= ".*postgres.*") of /:resolve-expression(expression=${features}) echo configuring postgres end-if {code} Example: {code} -Dfeatures="feature1 feature2" [default@local:9990 /] if (result ~= ".*feature1.*") of /:resolve-expression(expression=${features}) [default@local:9990 /] echo configuring feature1 [default@local:9990 /] end-if configuring feature1 [default@local:9990 /] if (result ~= ".*feature2.*") of /:resolve-expression(expression=${features}) [default@local:9990 /] echo configuring feature2 [default@local:9990 /] end-if configuring feature2 [default@local:9990 /] if (result ~= ".*feature3.*") of /:resolve-expression(expression=${features}) [default@local:9990 /] echo configuring feature3 [default@local:9990 /] end-if [default@local:9990 /] {code} was: Conditional expressions are great help for creating generic wildfly configurations with the CLI.
