Carlo Dapor created KARAF-5246:
----------------------------------

             Summary: Karaf shell command crashed on tab-completion when quotes are used
                 Key: KARAF-5246
                 URL: https://issues.apache.org/jira/browse/KARAF-5246
             Project: Karaf
          Issue Type: Bug
          Components: karaf-shell
    Affects Versions: 4.0.9
            Reporter: Carlo Dapor


Commands bail out when a starting quote preceed a tab-completion.

E.g.:

Type 
{code:java}
feature:install -s
{code}
 and hit the tab key, you are prompted with the question whether you want to see all 40+ completions.

But if you type 
{code:java}
feature:install -s "  # also with a single quote, btw
{code}
and then hit the tab key, you see an error: {color:red}Error executing command: String index out of range: 21{color}

The log shows:

What I would like to achieve, actually is with a StringsCompleter that accepts say 4 constants ("CODE", "TIME", "RUN", "ERROR"), I'd like to get multiple completions in the end.

In other words, I would like to be able to this:


> cool-command --expr '({color:#14892c}CODE{color}="A34" and {color:#14892c}TIME{color}=60) or ({color:#14892c}RUN{color} > 10 and {color:#14892c}ERROR{color}="E517")'

where each {color:#14892c}green{color} completion above I would tab-select as I type along.

This is currently not possible.
