Subject: Re: [PHP-DEV] php interactive shell without readline
From: ivan.enderlin@hoa-project.net ("Ivan Enderlin @ Hoa")

Hello,

This project is interesting but it is also possible to do it only with PH=
P.
As a proof of concept, I would like to share some links with you. First=20
one:=20
http://hg.hoa-project.net/Central/file/tip/Library/Console/Readline/Readl=
ine.php,=20
which is highly hackable: we can add mappings (esc, ctrl, abc=E2=80=A6), =
history=20
(when pressing key up and key down) and it works as an infinite=20
automaton based on the STATE_* constants. And thanks to PHP and its=20
static:: keyword, we can overload states, e.g.:=20
http://hg.hoa-project.net/Central/file/tip/Library/Console/Readline/Passw=
ord.php.=20
Hop, password is hidden :-).
This library has some limitations: it does not support multibytes=20
(Unicode) and has an unlimited history (which can cause memory errors),=20
but it is a (advanced-)POC. It works on Unix-based system, actually=20
STTY-based shells, and has a pretty simple fallback for DOS. It does not =

require PHP to be compiled --with-readline, it uses stty options=20
instead. And finally, it uses around 850 lines of codes (with comments + =

licences).

Best regards :-).
