[jboss-jira] [JBoss JIRA] (AS7-6004) Inconsistent tab completion behaviour between commands and arguments

[Jeff Mesnil (JIRA)]

    [ https://issues.jboss.org/browse/AS7-6004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736146#comment-12736146 ] 

Jeff Mesnil commented on AS7-6004:
----------------------------------

The issue is in jreadline Console[1].
It will only append a space after the completion if the completion corresponds to the beginning of the buffer line.

for deployment-over<TAB>, this works:
* full completion => deployment-overlay
* buffer line     => deployment-overlay
=> a white space is appended

for deployment-over a<TAB>, this does not work, since the completion is only for add:
* full completion => add
* buffer line     => deployment-overlay add
=> no whitespace appended

> When tab is used for completion, the behavior changes when there is only 1 remaining candidate.
> For commands, when the completion leads to a single candidate, a whitespace is appended and we can proceed to the arguments
> For arguments using a TabCompleter, when the completion leads to a single candidate, no whitespace is appended and we have to type it to be able to proceed to the next argument
>  
> Example:
> * deployment-over<TAB>
> => will complete to deployment-overlay<WHITESPACE><CURSOR> (a whitespace is appended to the single candidate)
> * deployment-overlay a<TAB>
> => will complete to deployment-over add<CURSOR> (no whitespace appended even though add is the only candidate matched)
