I looked at this. The approach I was going to take was to put into the C code
an "open", "close", "read", and "lseek" concept and that would need a new
"type" for a file descriptor. You might as well add "write" to complete the set.
There is nothing currently like that in the C code. I'm not sure if you want
to put this on top of open and its siblings or on top of fopen and let the C
I/O help some with the buffering.
From there, it becomes a matter of writing lisp to load in a "page" into a
buffer so it can be displayed and then a key map so the user can page
forward and backward. For searches I couldn't come up with a nice
solution so I was just going to loop loading a page and searching the page
until the match was found.
The second generation of this could have a fixed sized cache of pages so that
small movements (like back a page) would be instant and you could even
get fancier and pre-fetch the next page.
This could grow into a hugh beast. You would want to hook up to the
character set things so that it would detect and process all the different
characters sets (like UTF-8, etc) properly. And then, what the hell, you
might as well plop the nifty coloring modes on top as well so that
as you page through C text, it would be colored. In my case, I want to
plop a wireshark mode on top so that I can view network packets.
But, for my own personal case, I have way too many projects going already
so I didn't even post this to the list until just now. I think its a concept
whose time has come but I don't have the time right now. I'd love to
contribute to it if anyone wants to start.
