App::Cmd::Plugin::Prompt - plug prompting routines into your commands
version 1.005
In your app:
package MyApp; use App::Cmd::Setup -app => { plugins => [ qw(Prompt) ], };
In your command:
package MyApp::Command::dostuff; use MyApp -command; sub run { my ($self, $opt, $args) = @_; return unless prompt_yn('really do stuff?', { default => 1 }); ... }
my $input = prompt_str($prompt, \%opt)
This prompts a user for string input. It can be directed to persist until input is 'acceptable'.
Valid options are:
input: optional coderef, which, when invoked, returns the user's response; default is to read from STDIN.
output: optional coderef, which, when invoked (with two arguments: the prompt and the choices/default), should prompt the user; default is to write to STDOUT.
valid: an optional coderef which any input is passed into and which must return true in order for the program to continue
default: may be any string; must pass the 'valid' coderef (if given)
choices: what to display after the prompt; default is either the 'default' parameter or nothing
no_valid_default: do not test the 'default' parameter against the 'valid' coderef
invalid_default_error: error message to throw when the 'default' parameter is not valid (does not pass the 'valid' coderef)
my $bool = prompt_yn($prompt, \%opt);
This prompts the user for a yes or no response and won't give up until it gets one. It returns true for yes and false for no.
default: may be yes or no, indicating how to interpret an empty response; if empty, require an explicit answer; defaults to empty
my $input = prompt_any_key($prompt);
This routine prompts the user to "press any key to continue." ($prompt, if supplied, is the text to prompt with.
