865a2cdcbd Support definitions of keyword functions in Typed Racket. 
Caveats:
 - keyword function definitions do not define static
   bindings, thus limiting optimization opportunities
 - can't use `define:`, `lambda:`, etc with keywords
 - error messages sometimes expose the implementation
 - the optimizer skips most of the generated code for
   keyword functions definitions (user-level code is
   optimized)

a377c42357 Use the new syntax properties for checking keyword functions. 
Previously, some hacks were used to obtain the internal
identifiers that implemented keyword functions directly, and
give them types at startup.  Now, the primary "function"
(eg, `sort`) is given a type, and when used, the residual
syntax properties are used to find `sort` from the real
functions, and then the type of the real function is computed
from the type of `sort`.

Some creativity was required in the types of functions which
take optional arguments that when present, alter the return type,
such as `regexp-match*` and `file->list`.

bf95ee1052 Adjust datalog to cooperate with check syntax a little bit more. 
Specifically:
 - make predicate symbols and variables be original (and,
   in the former case, have srclocs)
 - remove the originality in the quoted syntax constants
   that the expansion introduces

I think there is probably something better that should be done
with those introduced syntax constants, possibly relacing
them with #f, or possibly replacing them with source location
lists, but I'm not sure how they are used, so I've just left
them in there.

(Also, very minor Rackety in check syntax)

77811e0e95 Adjust how the drracket repl iterates over expressions to make it more 
like textual-read-eval-print-loop

There is still a difference, however, because drracket's REPL has a
notion of multiple expressions that are submitted simultaneously that
textual-read-eval-print-loop doesn't. For example, if you type this at
the prompt:

  (car) (+ 1 2)

then textual-read-eval-print-loop will print out the error and then 3,
but drracket will print only the error (ditto if (car) were replaced
by a continuation abort).

This difference is, IMO, a good thing, since it lets you use a single
interaction to do multiple things, but stops as soon as there is an
error. (It is also how drracket has behaved for a long time.)

daa048719a fixed a bug in the ordering of how printing parameters are set up 
There was an exception raised and then handled internally when the
slideshow/pict-convert library was loaded; DrRacket loaded this
library during the dynamic-extent of a handler it installed into
the global-port-print-handler, which causes a (non-tail) infinite

b098ca7aa6 slideshow: run a slideshow' or main' submodule, if any 
A common Slideshow pattern is to put a subset of slides in its
own module with a `run-slides' function, and then you'd
(un)comment a `(run-slides)' call at the end of the module to
work on the subset by itself. Now, you can write
`(module+ main (run-slides))' atthe end of the module and not
have to comment it out. Adding `main' support to the `slideshow'
executable makes it more consistent with using `racket' directly.
Checking first for a `slideshow' submodule makes it possible
for `slideshow' and `racket' to do different things, in case
that's useful.

9e7548de61 new error message convention 
Add `raise-argument-error', `raise-result-error', `raise-arguments-error',
and `raise-range-error'.

The old convention was designed for reporting on a single (sometimes very
long line). The new convention is

 <name>: <short message>
   <field>: <detail>
   ...

If <detail> is long or itself spans multiple lines, then it may
also use the form

   <field>:
    <detail>

where each line of <detail> is indented by 3 spaces.

Backtrace information is shown as a multi-line "context" field.

50ad8dac1f When plot-new-window?' is #t, plot' and `plot3d' now create a frame in a new eventspace. This allows plot frames to be displayed programmatically. (Without this change, the frames are unresponsive until the REPL regains control.) 2012-05-25 13:11:46 +09:00

ee95182386 Made (require plot) more obvious in the plot introduction (suggested by Jens Axel Søgaard)

365ee2c70d 1d, 2d and 3d function renderers no longer sample outside the function's bounds 
This makes it more efficient to plot piecewise functions by drawing each piece with one renderer, and possible to plot functions with discontinuities by using a renderer to draw each continuous piece.

8fc49d41cf Improved bash completion script. 
Warning: I tried a bunch of things and it looks like it works, but I'm
not using bash regularly so there might be some problems in this.
Committing by request of the bashers.

It would still need some work to make it work as (I think) was intended.
For example _find_exe() should be used to find the current executable
when completing, but it's used at the toplevel.
