Bob Nystrom 9661a5b999 Fix a couple of bugs in the REPL. 
- Not sure what was going on, but fix #456. It makes more sense for the
  REPL to invoke the compiled code as a fiber than a function anyway.

- Flush stdout before reading from stdin since System.print() no longer
  does that automatically.

Bob Nystrom 91853a7fa9 Fix comment on foreign allocate function. 
Fix #453.
 2017-10-12 06:37:49 -07:00
Bob Nystrom 2021e086bf Don't automatically flush on every System.write(). 
It's handy because it ensures writes are flushed to the terminal before
any calls to read from stdin, but it's also gratuitously slow.

Instead, added a Stdout class with an explicit flush() method that can
be called by the user.

Fix #445.

Bob Nystrom 44a95e65c6 Set the token type after an invalid character error. 
Otherwise, it still has the previous token's type. This can cause it

Bob Nystrom c6eb0be990 Remove the negative number tests for bitwise not. 
They were inadvertently relying on undefined behavior in C and we get
different results on some compilers.

Until we decide how we want the operation to behave, for now, just
leave it unspecified.

Bob Nystrom 33a73ef1d5 Avoid using fpclassify() to detect infinity and nan. 
It's not supported in C++98. Instead, use isnan() and isinf(), which
seem to work? If nothing else, they are used elsewhere in Wren, so if
we're not going to use them here, we should fix the other places too.
 2017-01-12 21:34:11 -08:00
Bob Nystrom e8dfb1bf10 Don't test bitwise operations on operands that don't fit in u32. 
The current behavior is undefined in C when converting the double to a
u32, so the tests fail on some compilers. For now, I'm just removing
those parts of the tests because I'm not sure what I want the behavior
to be. Modulo? Truncate? Runtime error?

Bob Nystrom 08eceb7382 Check for duplicates when adding constants.

Bob Nystrom 500c7b0426 Add List constructors to docs. 2016-08-04 06:28:41 -07:00
Bob Nystrom 3666eae013 Tweak new list constructors. 
- Remove List.new(_). I was convinced by the issue discussion that
  using it is probably a bad idea. We don't want to encourage more nulls
  in the world than there are already are. So let's see if we can live
  without it and just have List.filled(). That way users think about
  what they're creating a list *of*.
- Added some more tests.
- Correctly handle being given a negative size.

Bob Nystrom 60a0353a27 Tweak list C API: 
- Rename "size" -> "count" to be consistent with other usage.
- Remove "Slot" from the function names, since that's implicit.
- Make the getListElement() just move the element to another slot. This
  matches other APIs where we distinguish accessing a value and
  converting it to some specific type.

Fix build, return false instead of NULL
 2016-07-06 06:46:35 -07:00
Bob Nystrom 0837917307 Use a hash function for numbers that doesn't tend to zero low bits. 
Just pulling the raw words out of a double means integers often map to
hashes with zero low bits. Then when we map that to an entry in the map,
all small integers end up in entry zero, leading to tons of collisions.

This mixes the bits around some like Java does to fix that.

Makes the map_numeric benchmark about 18% faster on my machine. On a
contrived benchmark that just uses keys up to 1000, this makes it 52x
(yes, *times) faster.
 2016-06-27 08:13:45 -07:00
Bob Nystrom 4e94195f26 Properly handle tombstones when inserting items into a map. 
Previously, you could get into a state where a key was present in the
map, but after a tombstone in the probe sequence. If they key was added
again, it stopped at the first tombstone and added it there, resulting
in the key being in the map multiple times.

Fix #373.
 2016-06-27 07:14:52 -07:00
Bob Nystrom bc29f43bbd Allow hosts with no module loader to still load optional modules. 
If the host doesn't set a loadModuleFn at all in the config, it should

Guesses whether the input is an expression or statement and handles it

prints "3" if you type in "1 + 2". \o/
 2016-06-09 19:16:41 -07:00
Bob Nystrom 689cd42269 Start writing the REPL in Wren. 
It doesn't actually execute code yet, but it:

- Supports left and right arrow keys for moving the cursor.
- Ctrl-C, Ctrl-D, Ctrl-A, and Ctrl-E for navigating.
- Syntax highlights the line (!).

The next step is to do a rough parse so that we can tell if the line
is an expression, statement, or needs more input. That will tell us
whether we need to interpret it at the top level (statement) and not
worry about a result, evaluate it as an expression and print the result,
or read more lines.
