[jboss-jira] [JBoss JIRA] (WFCORE-1614) Requesting CLI Equivalent of Remote Echo / set -x in non-interactive mode (from within scripts)

Petr Kremensky commented on WFCORE-1614:
----------------------------------------

I see a problem with control flow statements usage, as all commands are printed first, creating a lot of noise in output.

It could be quite difficult to re-create a problematic situation using the echoed commands (we should take into account that customer's scripts could have thousand of lines) - see 'set prop', reload, stop-embedded-server, asdqwe-error from else branch which was not executed.

[pkremens at dlocalhost]$ cat test.cli
embed-server

try
    :read-attribute(name=foo)
catch
    /system-property=catch:add(value=bar)
finally
    /system-property=finally:add(value=bar)
end-try

/system-property=*:read-resource

if (outcome == success) of /system-property=catch:read-attribute(name=value)
    set prop=Catch\ block\ was\ executed
    /system-property=finally:write-attribute(name=value, value=if)
else
    set prop=Catch\ block\ wasn\'t\ executed
    reload
    stop-embedded-server
    asdqwe-error
    /system-property=finally:write-attribute(name=value, value=else)
end-if
reload
stop-embedded-server

> We are proposing here to add a Cli option (command line option and an XML element) to make the CLI to echo the command and its options in non interactive mode. This will help to match a given command and its output.
> For example, the "ls -l" command output would be:
> [standalone at localhost:9990 /] ls -l
> ATTRIBUTE                   VALUE                                TYPE
