> Simple csh-like Command History
> -------------------------------
>
> Key: FELIX-3341
> URL: https://issues.apache.org/jira/browse/FELIX-3341
> Project: Felix
> Issue Type: Improvement
> Components: Gogo Shell
> Affects Versions: gogo.shell-0.10.0
> Reporter: Felix Meschberger
>
> Suggest to add a simple csh like command line history.
> * A new command "history" is added to the Shell class listing the command
> history
> * A new History class is added to manage a bounded, in-memory-only command
> history
> * Commands can be reused from the history using commands following this
> simple syntax:
> command = ( '!' spec ) | ( '^' subst ) .
> spec = '!' event [ ':' [ 'a' | 'g' ] 's' regex ] .
> event = ( '!' | idx | '?' find | string )
> idx = [ '-' ] { 0..9 } .
> find = string ( '?' | EOL ) .
> subst = pat '^' repl '^' EOL .
> regex = str pat str repl str EOL .
