-------------------------------
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
Attachments: FELIX-3341.patch
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 .
