Make elinks realy scriptable.

Hello, I'm a long time user of elinks, and recently, I tried to build a lua script to add to elinks the same
behavior than vimperator/pentadactyl hint mode :

You enter in the hint mode by pressing « f », all links in the page becomes highlighted and labelled, like
when you press « . » in elinks for showing links number. Then you begin to type some letters on your
keyboard : only the links with thoses char in the text become selected (the links number are updated for
counting only the selected links).

Ok, that's easy : I just have to fetch all links on the current document, and each time the user enter a key in
the message box, match the text with the link name for each link, and set the link as selected or not. I can do
this in lua !

Let's take a look in the lua api, there are some fonction described in the documentation, for interracting
with elinks core (open a message box…), but where is the api for the differents object (link, document) ?
It seems it as not been written…

Ok, let's take a look in the code. Omg ! the functions described in the documentation are the only existing
ones ! There is no way to get the document, no way to select a link, no way to jump to a link… This is what you
call a browser « highly customizable and can be extended via Lua or Guile scripts » ? Don't give me that
jazz !

So, as it seems that anything as to be done, let's think about what I expect from a true scriptable browser :

Control the browser and the navigation :

     * To be allowed to open a tab, close one
     * Set the current url, refresh the page
     * To be informed when the user select a link

Control the display :

     * Access to the statusbar
     * To be informed when the user press a key (even in a dialogbox)
     * Change the color in the page (highlight text, css…)

Control the document :

     * Get the links in the document
     * Select the current link
     * Modify the document (not the text, the document)
     * Fill forms

It's a big work to do, and I won't be able to do it for all the currents scripts languages provided in elinks; if
I had to choose one :

     * Guile : I have no experience with this language.
     * Python : Althought I like python, I think it is to heavy for use it as a script interpreter.
     * Perl : Don't make me laught !
     * Javascript : Why not; but debian as removed the js support for elinks, and nobody notice that the
documentation refers to scripts that are unusable now : is anybody using it ?
     * lua : I think it is a good choice : lightweight, and easy to code (as in the C code than the lua code)

Now we are in 2012, and lua allow objects, so we could give to the script a reflect of the elinks internal
structs : document, link, form, session…

The aim it is to give the user a maximum of control over the navigation. I appreciate to be able to script my
applications as I want (vim, awesome…) because each user has differents need, and you can't think about
every usage that will be made of a soft. I know it is a big modification, and will give a new face to elinks, and
even if I'm not a C developper, and want to do it; elinks is not dead, console apps aren't apps from past, and
elinks is the better web browser as complementary one !

Who's in ?
