DESCRIPTION

This module provides extended functionality for entering or changing text for command line programs.

The IO::Prompter module does a wonderful job of encapsulating a lot of user entry tasks in a really nice interface. One thing it does not do well is allow input for long-form text. Many version control systems use the approach of opening a window in your editor to deal with long-form text. This seems like a great solution and avoids a large number of nasty bits (like editing functions surrounding Unicode characters).

This module wraps up the functionality needed to use an editor in this fashion in a realtively straight-forward interface.

INTERFACE

new

Create new IO::EditPrompt object. This object can be used with multiple prompt calls. The optional paramters must be passed as a hashref.

dir

Specify a directory for the temporary file to edit.

default_editor

The name of a default editor if none is provided by the EDITOR environment variable.

editor

Force calling this program as the editor, independent of the environment. If this parameter is missing, the program will default to using the EDITOR environment variable. If there is no value for EDITOR, we try the supplied default_editor parameter. If none of these have values, we default to vim.

prompt( $prompt, $deftext )

Open the editor with the supplied $prompt and $deftext already filled in. Every line of the prompt text will be prefixed by the string # , the default text will be supplied as is. After the user saves any changes, the content of the file is read and any text that begins with # is removed. The result is returned to the caller.

If the cleaned up text is empty, the user is given an attempt to retry.

CONFIGURATION AND ENVIRONMENT

IO::EditPrompt relies on the EDITOR environment variable to supply a default editor to use.
