Elisp Reader

Elisp Reader

[Daniel Kraft]

Hi all,

yesterday and today I implemented the promised elisp reader and just 
pushed the changes.  Now Guile's elisp support in my branch should be 
somewhat "complete" because not only there's a compiler but also a 
genuine parser for elisp, handling for instance the [] vectors, all 
those fancy ?\C-\M-x character escape sequences and the syntax for 
circular structures with #n=/#n#.  I hope it is fairly complete and 
bug-free, but probably not (as usual) ;)

Feel free to look at it or try it out, I'd be interested to get testing 
results!  I could try to run some real elisp code through it...

Apart from that, I'm going to do a merge from master now (which made 
some problems last time with readline, hopefully I can get it to work 
now) and maybe really start writing some documentation -- where do you 
want me to put it?

Cheers,
Daniel

Fantastic work!

I know where you can find a whole pile of it. ;-)

I assume you don't follow the Emacs development mailing lists...   
There's been a little traffic recently about possible multithreading  
support and the effect on let-bound buffer-local variables.  Not much  
discussion so far on the details of the semantics of such cases, but  
Tom Tromey is looking into this stuff.  (I guess I kind of side- 
tracked some of the discussion onto guile-emacs stuff, oops.)  Have  
you given more thought to buffer-local variables, defvaralias, and  
other such headaches?  Tom's work and yours aren't quite overlapping,  
but you're close....
