NAME¶
Reply - read, eval, print, loop, yay!
VERSION¶
version 0.35
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.
