| Summary : event-based interface to Term::ReadLine::Gnu
|
Description :
The Term::ReadLine module family is bizarre (and you are encouraged not to
look at its sources unless you want to go blind). It does support
event-based operations, somehow, but it\'s hard to figure out.
It also has some utility functions for printing messages asynchronously,
something that, again, isn\'t obvious how to do.
This module has figured it all out for you, once and for all.
* $rl = new AnyEvent::ReadLine::Gnu key => value...
Creates a new AnyEvent::ReadLine object.
Actually, it only configures readline and provides a convenient way to call
the show and hide methods, as well as readline methods - this is a
singleton.
The returned object is the standard Term::ReadLine::Gnu object, all methods
that are documented (or working) for that module should work on this
object.
Once initialised, this module will also restore the terminal settings on a
normal program exit.
The callback will be installed with the \'CallbackHandlerInstall\', which
means it handles history expansion and history, among other things.
The following key-value pairs are supported:
* on_line => $cb->($string)
The only mandatory parameter - passes the callback that will receive lines
that are completed by the user.
The string will be in locale-encoding (a multibyte character string). For
example, in an utf-8 using locale it will be utf-8. There is no portable
way known to the author to convert this into e.g. a unicode string.
* prompt => $string
The prompt string to use, defaults to \'> \'.
* name => $string
The readline application name, defaults to \'$0\'.
* in => $glob
The input filehandle (should be a glob): defaults to \'*STDIN\'.
* out => $glob
The output filehandle (should be a glob): defaults to \'*STDOUT\'.
* $rl->hide
* AnyEvent::ReadLine::Gnu->hide
These methods _hide_ the readline prompt and text. Basically, it removes
the readline feedback from your terminal.
It is safe to call even when AnyEvent::ReadLine::Gnu has not yet been
initialised.
This is immensely useful in an event-based program when you want to output
some stuff to the terminal without disturbing the prompt - just \'hide\'
readline, output your thing, then \'show\' it again.
Since user input will not be processed while readline is hidden, you should
call \'show\' as soon as possible.
* $rl->show
* AnyEvent::ReadLine::Gnu->show
Undos any hiding. Every call to \'hide\' has to be followed to a call to
\'show\'. The last call will redisplay the readline prompt, current input
line and cursor position. Keys entered while the prompt was hidden will be
processed again.
* $rl->print ($string, ...)
* AnyEvent::ReadLine::Gnu->print ($string, ...)
Prints the given strings to the terminal, by first hiding the readline,
printing the message, and showing it again.
This function can be called even when readline has never been initialised.
The last string should end with a newline.
