ae70a03383 Address #306 - Add unicode escapes.
Unicode escapes have the same syntax as go - \uXXXX or \UXXXXXXXX.

65379741f7 Address edge case of reduce2 when ind is empty.
Same for accumulate 2.
2020-03-27 12:45:40 -05:00
Calvin Rose
3eb0927a2b Add accumulate(2) and reduce2
These functions are variations on reduce and can be quite useful.
Improve error message for jpm as well.

b0d8369534 Increase reference accuracy of on-stack close envs.
Using a bitset to indicate which stack values are upvalues, we
can more accurately track when a reference to a stack value
persists after the stack frame exits.

6123c41f13 Harden semantics for and and or macros.
There was perviously a bit of fuzziness on returning false/nil
from these macros that has been removed.

734c85d7ef Properly handle recursion with labels.
Use an empty buffer, which has pointer equality semantics, for
tag from a label.

59d288c429 Add prompt and return.
User friendly delimited continuations. While this was doable with
signals before, this does not require C and will play nicely with
existing error handling, defers, and with statements.

4fe005e3c3 Add righthand operator overloading.
This is like python. Now, we just need to readd fuzzy
comparisons to have what python needs. Overloading
math functions would be neat, too.

7c92c64730 Remove mutable operators on inttypes.
Mutations break hash table invariants, are a rather
silly performance optimization for a language like Janet.

3d40c95e80 Add ability to Janet signal from C functions.
While C functions are not re-entrant, signaling from a C function
can be used to implement async returns. When resuming a fiber that
signalled from within a C function, the fiber is started after the
instruction that emitted the signal. The resume argument is used
as the return result from the c function.

022be217a2 Remove ==, not==, and order[<,<=,>,>=].
This unifies equality and comparison checking. Before, we had
separate functions and vm opcodes for comparing general values vs.
for comparing numbers, where the numberic functions were polymorphic and
had special cases for handling NaNs. By unfiying them, abstract types
can now better integrate with other number types and behave as keys.

For now, the old functions are aliased but will eventually be removed.

f1afc5b0b4 Address #214
This adds several common patterns, which are defined in
boot.janet. This essentially gives more primitive patterns
to work with out of the box.

Fix build when JANET_REDUCED_OS is defined.

49954c7a30 Remove top-level unquote for comptime macro
True top level unquote currently requires basically double compilation
as it currently stands. Also, implementing such double compilation
looses all source mapping information. This is a compromise
implementation that makes it clear that this works differently than
a true top-level unquote.
2019-12-04 19:53:13 -06:00
Calvin Rose
2487162ccf Add top level unquote and macro envs.
This improves macros that eval their arguments and
makes them easier to write.

4199c42fe2 Add support for nested quasiquotation.

aee1687215 Add RNG functionality to the math/ module.
The new RNG wraps up state for random number generation, so
one can have many rngs and even marshal and unmarshal them.
Adds math/rng, math/rng-uniform, and math/rng-int.

Also introduce `in` and change semantics for
indexing out of range. This commit enforces stricter
invariants on keys when indexing via a function call
on the data structure, or the new `in` function.

The `get` function is now more lax about keys, and will
not throw an error when a bad key is used for a data structure, instead
returning the default value.

6ceaf9d28d Add with-vars
This helps for temporarily setting vars in a safe
manner that is guaranteed not to leave vars in a bad state
(assuming that a fiber does not emit debug or use signal and
 is never resumed).

d47804d222 Add prin, eprint, and eprin functions.
The print family of functions now writes output
to an optional buffer instead of a file bound to :out.
This means output can be more easily captured an redirected.

7910a5feef Add compile time arity checking.
This should help catch a number of errors, but it
is a very shallow implementation of type checking. It will
catch some common misuses of functions at compile time
rather than runtime.
2019-09-30 19:50:42 -05:00
Calvin Rose
b26a7bb22a Disallow the empty string for some string fns.
This will prevent these functions from being run
with empty strings, which usually produces useless
output, as the internal string search algorithm will
never "find" empty strings. This is by design, as it is
not always obvious which empty strings should be found in
the search text.

8cda06b995 GCC seemed to not fill array of computed gotos.
This is expected as per the C standard, but segfaulted
unless all 255 labels were added.

a8afc5b81f Sourcemapping uses line, column instead of offsets.
This should be friendlier to most users. It does, however, mean
we lose range information. However, range information could be
recovered by re-parsing, as janet's grammar is simple enough to do this.
2019-09-22 17:18:28 -05:00
Calvin Rose
39f1d81fd4 Use :length method for (length abstract)
Also adds the janet_lengthv API call. This is
needed because janet_length returns a 32 bit integer, where
as lengthv lets us return larger values (useful for typed arrays).

janet_mcall is an api function that should make it easier to call
a janet method from C code. It shares a similar signature with
janet_call.

54a04b5894 Fix some more recursion issues with pegs.
A keyword reference only counts as visited if we have
it as cached in the memoized->table, and we know it was
originally referenced from the same grammar table. If these
two conditions are true, then compilation must work correctly.

Also add janet_table_get_ex.

133ad0d355 Add test for longstring matcher using backmatches. 2019-08-24 19:02:55 -04:00
Calvin Rose
711fe64a51 Add backmatch operator to pegs.
(backmatch [tag?]) is similar to a back reference in regular expressions
(NOT to backwards capture in a peg). It only matches a pattern if
it exactly matches the text of the last capture. It does not consume
or push any captures to the capture stack.

Fix compiler bug when compiling desturctured bindings in a top-level

easier.
2019-07-07 23:18:39 -05:00
Calvin Rose
b8032ec61d Add propagate function and opcode
This allows better stacktraces when manually intercepting
signals to clean up resources. Also allows functionality
from Common Lisp's unwind-protect, such as calling cleanup code
while unwindinding the stack, restarting on certain signals, and
just in general having more control over signal and signal propagation.

Also fix a bug encountered while implementing with-resource in the
compiler. Desturcturing arguments that were not the last argument
would often result in bad code generation, as slots used to destructure
the earlier arguments would invalidate the later parameters. This is
fixed by allocating all named parameters before doing any destructuring.
