Thanks, but i hope you know that there already exist a wild variety of "solutions"

• Zoidberg
• psh
• Devel::REPL

• ...

especially perldebug comes with a variety of unknown goodies, like tab completion, introspection and doc lookup and is backwards compatible.

I once spend time adding patching the debugger to Data::Dump of the evaled line and allowing multiline commands ( talk ... sorry slides are offline ATM)

yep, OS independence is nice ... though I'm thinking about reusing Brian's powertools

> The eval which evaluates each line has strict and warnings switched off, so you can use things like barewords. Thus the following also works fine and feels slightly more shell-like:

> cd bin

two problems

• the Shell code should be production ready, thus allowing cut&paste
• as soon as you use a path separator like / barewords would fail (parser sees regex)

my idea is to allow a DWIM typing with barewords and path, but to visually translate to correct syntax

i.e. one types

> cd /home/user

but display and history would automatically shows

> cd '/home/user'

(tab completion needs syntax awareness anyway and it'll be a service for people coming from sh)
