Have you checked whether POE::Wheel::ReadLine::Gnu passes POE::Wheel::ReadLine's tests?

Not yet, since I'm pretty sure it doesn't pass the tests - for now. I wanted to have that working first, and care about compatibility and tests later... Ill update the OP with results as I get them.

Thanks for answering; I'll notice the mailing list.

update: ...and thank you for POE! It rocks! ;-)

update 2: Test output:

The failures only show differences between the two implementations; for GNU readline:

• 'delete words' - killing a word at bol (beginning-of-line) doesn't kill a following space
• 'transpose' - transposing two previous chars is possible at eol

The tests for POE::Wheel::ReadLine are far from complete; I didn't yet look into the arguments to new() and how they would translate to P::W::RL::Gnu, so I suspect incompatibilities in areas not covered by the tests (yet).

I think the Morgan Stanley people (...) may be interested in (...) a viable replacement for the existing module.

SCNR to the temptation of giving an example of how easy it is to twist a whole statement with the use of some ellipsis... ;-)

It might be a viable replacement, and if refined, it is; and "relatively inexpensive way" is an understatement, because all there is to it already can be found in the GNU readline library.

Dunno how that has been in the beginning of POE::Wheel::ReadLine. As for now, calling the GNU RL lib via Term::ReadLine::Gnu in POE context is straightforward, since it supports the callback execution model.

The functions needed in POE context, for most of its functionality, are:

• $self->rl_callback_handler_install
• $self->rl_callback_read_char
• $self->rl_deprep_terminal
• $self->rl_insert_text
• $self->rl_set_prompt
• $self->rl_redisplay

all of which (and oodles of more functions) are nicely explained in the GNU readline info pages.

I could step in and release a POE::Wheel::ReadLine::Gnu module compatible to POE::Wheel::ReadLine, and I would do so if you as "grandfather POE" would favor that; but I'd rather have the original authors of P:W:RL ("the Morgan Stanley people" ?) do the revision, for they have more insight into POE. Besides, I don't want to take over things without need, nor spoil effort.

That said - if nobody answers on the mailing list, I'll just do my best in coding and post it here or send it to you for inclusion.
