function pointer. - Add the
u
format specifier to printf family functions. - Allow printing 64 integer types in
printf
andstring/format

- Importing modules that start with
/
is now the only way to import from project root. Before, this would import from / on disk. Previous imports that did not start with.
or/

in the prototype table to tag the output. match
macro implementation changed to be tail recursive.- Adds a :preload loader which allows one to manually put things into
module/cache
. - Add
buffer/push
function. - Backtick delimited strings and buffers are now reindented based on the column of the opening delimiter. Whitespace in columns to the left of the starting column is ignored unless there are non-space/non-newline characters in that region, in which case the old behavior is preserved.

(error)
combinator in PEGs is now optional. - Add
(line)
and(column)
combinators to PEGs to capture source line and column. This should make error reporting a bit easier. - Add

ev/
module. This exposes a fiber scheduler, queues, timeouts, and other functionality to users for single threaded cooperative scheduling and asynchronous IO. - Add
net/accept-loop
andnet/listen
. These functions break downnet/server
into it's essential parts and are more flexible. They also allow further improvements to these utility functions. - Various small bug fixes.

. - Remove
==
,not==
,order<
,order>
,order<=
, andorder>=
. Instead, use the normal comparison and equality functions. - Let abstract types define a hash function and comparison/equality semantics. This lets abstract types much better represent value types.

- Update documentation.
- Add
var-
- Add
module/add-paths
- Add
file/temp

thread/
module to the core. - Allow seeding RNGs with any sequence of bytes. This provides
a wider key space for the RNG. Exposed in C as
janet_rng_longseed

and similar functions that could cause breakpoints to be skipped. - Add a number of new math functions.
- Improve debugger experience and capabilities. See examples/debugger.janet for what an interactive debugger could look like.
- Add
debug/step
(janet_step in the C API) for single stepping Janet bytecode. - The built in repl now can enter the debugger on any signal (errors, yields, user signals, and debug signals). To enable this, type (setdyn :debug true) in the repl environment.
- When exiting the debugger, the fiber being debugged is resumed with the exit value
of the debug session (the value returned by
(quit return-value)
, or nil if user typed Ctrl-D). (quit)
can take an optional argument that is the return value. If a module contains(quit some-value)
, the value of that module returned to(require "somemod")
is the return value. This lets module writers completely customize a module without writing a loader.- Add nested quasiquotation.
- Add
os/cryptorand
- Add
prinf
andeprinf

. - Add
in
function to index in a stricter manner. Conversely,get
will now not throw errors on bad keys. - Indexed types and byte sequences will now error when indexed out of range or with bad keys.
- Add rng functions to Janet. This also replaces the RNG behind
math/random
andmath/seedrandom
with a consistent, platform independent RNG. - Add
with-vars
macro. - Add the
quickbin
command to jpm. - Create shell.c when making the amalgamated source. This can be compiled with janet.c to make the janet interpreter.

function to the core, which invokes Janet's CLI interface. This basically moves what was init.janet into boot.janet. - Improve flychecking, and fix flychecking bugs introduced in 1.4.0.
- Add
prin
,eprint
,eprintf
andeprin
functions. The functions prefix with e print to(dyn :err stderr)
- Print family of functions can now also print to buffers
(before, they could only print to files.) Output can also
be completely disabled with
(setdyn :out false)
. printf
is now a c function for optimizations in the case of printing to buffers.
1.4.0 - 2019-10-14
- Add
quit
function to exit from a repl, but not always exit the entire application. - Add
update-pkgs
to jpm. - Integrate jpm with https://github.com/janet-lang/pkgs.git. jpm can now install packages based on their short names in the package listing, which can be customized via an env variable.
- Add
varfn
macro - Add compile time arity checking when function in function call is known.
- Added
slice
to the core library. - The
*/slice
family of functions now can take nil as start or end to get the same behavior as the defaults (0 and -1) for those parameters. string/
functions that take a pattern to search for will throw an error when receiving the empty string.- Replace (start:end) style stacktrace source position information with line, column. This should be more readable for humans. Also, range information can be recovered by re-parsing source.

,:-
,:*
,:/
,:>
,:==
,:<
,:<=
, and:>=
methods will work with the corresponding built-in arithmetic functions. This means built-in integer types can now be used as normal number values in many contexts. - Allow (length x) on typed arrays an other abstract types that implement the :length method.

1.0.0 - 2019-07-01
- Add
with
macro for resource handling. - Add
propagate
function so we can "rethrow" signals after they are intercepted. This makes signals even more flexible. - Add
JANET_NO_DOCSTRINGS
andJANET_NO_SOURCEMAPS
defines in janetconf.h for shrinking binary size. This seems to save about 50kB in most builds, so it's not usually worth it. - Update module system to allow relative imports. The
:cur:
pattern inmodule/expand-path
will expand to the directory part of the current file, or whatever the value of(dyn :current-file)
is. The:dir:
pattern gets the directory part of the input path name. - Remove
