TODO for (R6RS BASE)
|
|
|
|
* Compiler + libraries:
|
|
- letrec and letrec* restrictions (references and multiple returns)
|
|
- prohibit export of mutable bindings
|
|
- library versioning
|
|
- library phases (simply ignore)
|
|
- internal imports
|
|
- Recognize (define x)
|
|
- Add identifier-syntax
|
|
- Add do, let*-values.
|
|
|
|
* Numerics:
|
|
- Add rational, complex, and single-precision numbers
|
|
- Make sure the following primitives work:
|
|
|
|
rationalize
|
|
|
|
make-rectangular make-polar
|
|
real-part imag-part
|
|
magnitude angle
|
|
|
|
expt log
|
|
sin cos tan
|
|
asin acos atan
|
|
|
|
sqrt exact-integer-sqrt
|
|
|
|
number? complex? real? rational? integer?
|
|
real-valued? rational-valued? integer-values?
|
|
|
|
exact? inexact? ->exact ->inexact
|
|
|
|
real->flonum real->single real->double
|
|
|
|
= < <= > >=
|
|
zero? positive? negative?
|
|
odd? even?
|
|
finite? infinite? nan?
|
|
min max abs
|
|
|
|
+ - * /
|
|
|
|
div mod div-and-mod
|
|
div0 mod0 div0-and-mod0
|
|
|
|
gcd lcm (don't deal with inexact ints yet)
|
|
|
|
floor ceiling truncate round
|
|
|
|
number->string(radix,precision) string->number(radix)
|
|
|
|
* Read:
|
|
- recognize rational, complex and flonum syntax
|
|
- recognize inline-hex sequences (strings, chars, and symbols)
|
|
- #!r6rs
|
|
- #\ sequnces: nul, alarm, backspace, tab, linefeed, vtab, page,
|
|
return, esc, space, delete
|
|
- respect unicode constituents
|
|
- recognize \a, \b, \t, \n, \v, \f, \r, \", \\, \<lf>, \<spc>,
|
|
\xXXX; sequences in strings.
|
|
- Add unsyntax, unsyntax-splicing, and quasisyntax.
|
|
|
|
* Bytevectors:
|
|
- equal? for bytevectors
|
|
|
|
* Strings:
|
|
- string-copy
|
|
- string-fill!
|
|
|
|
* Vectors:
|
|
- vector-fill!
|
|
- vector-map
|
|
- vector-for-each
|
|
|
|
* Errors:
|
|
- (error who msg irritants ...)
|
|
- (assertion-violation who message irritants ...)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Completed for (R6RS BASE):
|
|
- Add let-syntax and letrec-syntax
|
|
numerator denominator
