Janet 1.28.0

Overview

• Various bug fixes
• Make nested short-fn's behave a bit more predictably (it is still not recommended to nest short-fns).
• Add os/strftime for date formatting.
• Fix ev/select on threaded channels sometimes live-locking.
• Support the NO_COLOR environment variable to turn off VT100 color codes in repl (and in scripts).
  See http://no-color.org/
• Disallow using (splice x) in contexts where it doesn't make sense rather than silently coercing to x.
  Instead, raise a compiler error.
• Change the names of :user8 and :user9 sigals to :interrupt and :await
• Change the names of :user8 and :user9 fiber statuses to :interrupted and :suspended.
• Add ev/all-tasks to see all currently suspended fibers.
• Add keep-syntax and keep-syntax! functions to make writing macros easier.

Janet 1.27.0

• Change semantics around bracket tuples to no longer be equal to regular tuples.
• Add index argument to ffi/write for symmetry with ffi/read.
• Add buffer/push-at
• Add ffi/pointer-buffer to convert pointers to buffers the cannot be reallocated. This
  allows easier manipulation of FFI memory, memory mapped files, and buffer memory shared between threads.
• Calling ev/cancel on a fiber waiting on ev/gather will correctly
  cancel the child fibers.
• Add (sandbox ...) function to core for permission based security. Also add janet_sandbox to C API.
  The sandbox allows limiting access to the file system, network, ffi, and OS resources at runtime.
• Add (.locals) function to debugger to see currently bound local symbols.
• Track symbol -> slot mapping so debugger can get symbolic information. This exposes local bindings
  in debug/stack and disasm.
• Add os/compiler to detect what host compiler was used to compile the interpreter
• Add support for mingw and cygwin builds (mingw support also added in jpm).

Janet 1.26.0

• Add ffi/malloc and ffi/free. Useful as tools of last resort.
• Add ffi/jitfn to allow calling function pointers generated at runtime from machine code.
  Bring your own assembler, though.
• Channels can now be marshalled. Pending state is not saved, only items in the channel.
• Use the new .length function pointer on abstract types for lengths. Adding
  a length method will still work as well.
• Support byte views on abstract types with the .bytes function pointer.
• Add the u format specifier to printf family functions.
• Allow printing 64 integer types in printf and string/format family functions.
• Allow importing modules from custom directories more easily with the @ prefix
  to module paths. For example, if there is a dynamic binding :custom-modules that
  is a file system path to a directory of modules, import from that directory with
  (import @custom-modules/mymod).
• Fix error message bug in FFI library.

Janet 1.25.1

• Add memcmp function to core library.
• Fix bug in os/open with :rw permissions not correct on Linux.
• Support config.mk for more easily configuring the Makefile.

Janet 1.25.0

• Windows FFI fixes
• Fix PEG if-not combinator with captures in the condition
• Fix bug with os/date with nil first argument
• Fix bug with net/accept on Linux that could leak file descriptors to sub-processes
• Reduce number of hash collisions from pointer hashing
• Add optional parameter to marshal to skip cycle checking code

Janet 1.24.1

• Fix FFI bug on Linux/Posix
• Improve parse error messages for bad delimiters.
• Add optional name parameter to the short-fn macro.

Janet 1.24.0

• Add FFI support to 64-bit windows compiled with MSVC
• Don't process shared object names passed to dlopen.
• Add better support for windows console in the default shell.c for auto-completion and
  other shell-like input features.
• Improve default error message from assert.
• Add the tabseq macro for simpler table comprehensions.
• Allow setting (dyn :task-id) in fibers to improve context in supervisor messages. Prior to
  this change, supervisor messages over threaded channels would be from ambiguous threads/fibers.

Janet 1.23.0

This release brings a number of new features that will make Janet useful in even more domains, including mutexes and reader-writer locks to the ev module to improve interactions with multi-threaded, native code, better named arguments support, and an experimental FFI module. Also a number of improvements and simplification to Janet's debugging capabilities have been made, and exposed with the new debugger function.

• Add experimental ffi/ module for interfacing with dynamic libraries and raw function pointers. Only available
  on 64 bit linux, mac, and bsd systems.
• Allow using &named in function prototypes for named arguments. This is a more ergonomic
  variant of &keys that isn't as redundant, more self documenting, and allows extension to
  things like default arguments.
• Add delay macro for lazy evaluate-and-save thunks.
• Remove pthread.h from janet.h for easier includes.
• Add debugger - an easy to use debugger function that just takes a fiber.
• dofile will now start a debugger on errors if the environment it is passed has :debug set.
• Add debugger-on-status function, which can be passed to run-context to start a debugger on
  abnormal fiber signals.
• Allow running scripts with the -d flag to use the built-in debugger on errors and breakpoints.
• Add mutexes (locks) and reader-writer locks to ev module for thread coordination.
• Add parse-all as a generalization of the parse function.
• Add os/cpu-count to get the number of available processors on a machine

Janet 1.22.0

• Prohibit negative size argument to table/new.
• Add module/value.
• Remove file/popen. Use os/spawn with the :pipe options instead.
• Fix bug in peg thru and to combinators.
• Fix printing issue in doc macro.
• Numerous updates to function docstrings
• Add defdyn aliases for various dynamic bindings used in core.
• Install janet.h symlink to make Janet native libraries and applications
  easier to build without jpm.
