re.pl

read, eval, print, loop with tabcompletion and persistent lexicals

repl

DESCRIPTION

re.pl tabcompletes to variables, special file handles, built in functions, operators, control structures and modules if you have Term::ReadLine::Gnu or Term::ReadLine::Zoid installed.

Documentation is also available straight from the REPL;

re.pl$ perldoc Term::E<TAB>
Term::ExtendedColor                     Term::ExtendedColor::TTY::Colorschemes
Term::ExtendedColor::TTY                Term::ExtendedColor::Xresources

A list of available modules is created on the first run, or when the --genmod flag is specified.

OPTIONS

-g, --genmod    re-create a list of available modules on the system

-h, --help      show the help and exit
-v, --version   show version info and exit
-m, --man       show documentation and exit

COMMANDS

perldoc My::Module # Invoke perldoc; will use the system $PAGER
:q, exit           # exit re.pl

ENVIRONMENT

The behavior in the prompt is controlled by several variables. First, it's recommended to have the Term::ReadLine::Gnu module installed. Without it, tab-completion and a vi keymap can not be guaranteed.

A couple of records in $HOME/.inputrc will make working with perldoc easier, assuming you are using Bash (or anything other that uses readline) as your shell:

set editing-mode vi
set keymap vi-insert

$if re.pl
  "\C-e": "perldoc perlre\n"
  "\C-g": "perldoc perlguts\n"
  "\C-o": "perldoc perlop\n"¶
  "\C-p": "perldoc perlipc\n"
  "\C-u": "perldoc perlunicode\n"¶
  "\C-v": "perldoc perlvar\n"¶
$endif
