[jboss-jira] [JBoss JIRA] (AS7-2664) Tab Completion help, found an example where = are added to the tab completion, it would be nice if commands would be post pended with either = or : or ( as appropaite

Dave Ryan commented on AS7-2664:
--------------------------------

There would be a difficulty here in using the Tab completion to open the optional arguments, such as adding a "(" character. For many of the existing operations, the operation name can be filled with Tab completion, but another operation contains the same string of words. For example:

bq. [standalone at localhost:9999 subsystem=datasources] :read-resource

If you then hit Tab, you get the following:

bq. read-resource               read-resource-description

The read-resource operation, however, also has some optional arguments. If you open the "(" bracket:

bq. [standalone at localhost:9999 subsystem=datasources] :read-resource(

And then hit Tab to show the options:

bq. include-runtime=   proxies=           recursive=

This would make it difficult to differentiate between the user's intention to fill the name of the operation, or add arguments. Jim, what would you think about having a {{--help}} wrapper, as raised in [AS-1758|https://issues.jboss.org/browse/AS7-1758]? This would allow the user to use the existing tab compeltion to fill out the operation name, and then use the {{operation-name --help}} option to effectively shortcut to running the {{read-operation-description(name=NameOfOperation)}}. 

The advantage I see here is a nice compromise between the existing Tab completion, and being able to query the use of optional arguments without interupting the workflow of the existing operation (in other words, not having to undo the Tab completion of the operation name, and retype the read-operation-description, read it, and then type out the original operation again). Thoughts?

> More help hinting at the format of commands, found this one by accident in the attached screen shot that had = signs which makes it very  nice, so far had not noticed the tabs adding in syntax help like that before.
