bc2ebce086 Make ctrl-d behave like delete, but exit on an empty line. 
This is the default readline behavior.

6bc67b70a6 Address #294 
Correct invalid format string, which masked a panic
with another, less useful panic.

6b093bdcca Address #288 and partially #287 
The %q formatter for janet_formatc now expects a Janet, not a JanetString or
JanetSymbol or JanetKeyword.

Also fix some reference counting issues with threads when destroying
threads, which should fix #287's
SIGSEGV. Still fails to send messages sometimes, though.

8262290bff Improve C string format (janet_formatc, janet_panicf) 
The supported formatters here now match up more with
the string/format, buffer/format, printf, eprintf, etc.

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

05bd5767de Add label macro.

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.

 2020-02-23 14:47:29 -06:00
Calvin Rose
6a13703e32 Add signal and fiber/can-resume?. 
These additions, along with the change that user signals 0-4 cannot
be resumed, allow delimited continuation semantics, while repsecting
existing forms like `defer`, `with`, `with-vars`, etc.

aaabca6fc7 Make flychecker handle more kinds of defs. 
This should help when redefining certain forms. Will also
not do functional arity checking against nil forms, as that
is the default value when a def doesn't evaluate.

f4a46ba6ea Add methods to streams. 
This makes streams polymorphic with files in many cases.
printf family functions still need porting.

Calvin Rose
79bb9e54d5 Remove direct references to file descriptors. 
If a descriptor is freed by the Janet code, other
uses of that descriptor, say in the event loop, need
to know that it has been closed.

8ae6ae65a1 Merge branch 'master' into net 2020-02-09 20:00:58 -06:00
Calvin Rose
f4d7fd97f6 Working TCP echo server and client. 
Required a few changes to APIs, namely janet_root_fiber()
to get topmost fiber that is active in the current scheduler.
This is distinct from janet_current_fiber(), which gets the bottom
most fiber in the fiber stack - it might have a parent, and so cannot
be reliably resumed.
This is the kind of situation that makes symmetric coroutines more
attractive.

3fdc053d6c Add flush and eflush (#278) 
These functions interact with Janet's dynamically scoped
IO functions in a manner that is more useful the file/flush.
We can still redirect to a buffer without changing our code.

333ae7c4f8 Make amalgamtion the default when building. 
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC

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.

2f9ed8a572 Use memmove instead of copying. 
Also some comment things, and re-add old code from linenoise.
It seems to have a purpose for some keyboard layouts, so I will leave
it.

Make REPL key bindings more similar to those on GNU readline.
 2020-01-21 23:09:45 -06:00
crocket
8162c64ca3 Make REPL key bindings more similar to those on GNU readline. 
* I deleted Alt-H and Alt-L because Ctrl-F and Ctrl-B serve the same
roles.
* Ctrl-W, Alt-D, Alt-F, and Alt-B behave more similarly to the same
key bindings on GNU readline.
* Improved documentation of REPL keybindings on man page.
* Home and End keys now work on more terminal environments.
* Removed bindings for `Esc OH` and `Esc OF` because andrewchambers
doesn't need those bindings and the bindings don't seem to make much
sense for Home and End. `Esc O` is Single Shift Select of G3 Character
Set in xterm. https://invisible-island.net/xterm/ctlseqs/ctlseqs.html

This means we can add new properties to abstract types without

needing to add many NULL fields to the type.

ea02b2fde9 Use siphash for string hashing.

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.

099a957e6c Update macex1 to properly handle break 
Things mostly worked fine, but technically
break should be handled as a special form not a function call.

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.

3492ed6d88 Windows installer pulls version from interpreter. 
This should make version updates simpler. Also
try an make installer write to ProgramFiles instead
of ProgramFiles (x86) for 64 bit build.

6a39c4b91d Pass thread body explicitly in thread/new. 
Doing it via thread/send make sense, but is a bit
strange. Passing the body explicitly will make more
sense to API users.

4238379552 Use _setjmp/_longjmp on BSDs. 
This doesn't save the signal mask so should be a bit faster.

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.
