NAME

Reply - read, eval, print, loop, yay!

VERSION

version 0.36

SYNOPSIS

use Reply;

Reply->new(config => "$ENV{HOME}/.replyrc")->run;

DESCRIPTION

NOTE: This is an early release, and implementation details of this module are still very much in flux. Feedback is welcome!

Reply is a lightweight, extensible REPL for Perl. It is plugin-based (see Reply::Plugin), and through plugins supports many advanced features such as coloring and pretty printing, readline support, and pluggable commands.

METHODS

new(%opts)

Creates a new Reply instance. Valid options are:

config

Name of a configuration file to load. This should contain INI-style configuration for plugins as described above.

plugins

An arrayref of additional plugins to load.

run

Runs the repl. Will continue looping until the read_line callback returns undef (typically when the user presses Ctrl+D), or the loop callback returns false (by default, the #q command quits the repl in this way).

step($line, $verbose)

Runs a single iteration of the repl. If $line is given, it will be used as the string to evaluate (and the prompt and read_line callbacks will not be called). If $verbose is true, the prompt and line will be displayed as though they were typed. Returns true if the repl can continue, and false if it was requested to quit.

CONFIGURATION

Configuration uses an INI-style format similar to the configuration format of Dist::Zilla. Section names are used as the names of plugins, and any options within a section are passed as arguments to that plugin. Plugins are loaded in order as they are listed in the configuration file, which can affect the results in some cases where multiple plugins are hooking into a single callback (see Reply::Plugin for more information).

In addition to plugin configuration, there are some additional options recognized. These must be specified at the top of the file, before any section headers.

script_file

This contains a filename whose contents will be evaluated as perl code once the configuration is done being loaded.

script_line<n>

Any options that start with script_line will be sorted by their key and then each value will be evaluated individually once the configuration is done being loaded.

NOTE: this is currently a hack due to the fact that Config::INI doesn't support multiple keys with the same name in a section. This may be fixed in the future to just allow specifying script_line multiple times.
