[KARAF-5246] The command parser should be more tolerant when parsing the line
during completion
> Karaf shell command crashes 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
> Priority: Major
>
> Commands bail out when a starting quote - single or double quote - preceedes
> 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.
