Changelog
All notable changes to this project will be documented in this file.
Unreleased
- 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. This adds more fields to abstract types, which will generate warnings when compiled against other versions.
- Remove Emscripten build. Instead, use the amalgamated source code with a custom toolchain.
- Update documentation.
1.6.0 - 2019-12-22
- Add
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
. - Fix issue in
resume
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
to be have likeprintf
andeprintf
. The latter two functions now including a trailing newline, like the other print functions. - Add nan?
- Add
janet_in
to C API. - Add
truthy?
- Add
os/environ
- Add
buffer/fill
andarray/fill
- Add
array/new-filled
- Use
(doc)
with no arguments to see available bindings and dynamic bindings. jpm
will useCC
andAR
environment variables when compiling programs.- Add
comptime
macro for compile time evaluation. - Run
main
functions in scripts if they exist, just like jpm standalone binaries. - Add
protect
macro. - Add
root-env
to get the root environment table. - Change marshalling protocol with regard to abstract types.
- Add
show-paths
tojpm
. - Add several default patterns, like
:d
and:s+
, to PEGs. - Update
jpm
path settings to make usingjpm
easier on non-global module trees. - Numerous small bug fixes and usability improvements.
1.5.1 - 2019-11-16
- Fix bug when printing buffer to self in some edge cases.
- Fix bug with
jpm
on windows. - Fix
update
return value.
1.5.0 - 2019-11-10
os/date
now defaults to UTC.- Add
--test
flag to jpm to test libraries on installation. - Add
math/rng
,math/rng-int
, andmath/rng-uniform
. - 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.
- Add
cli-main
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.
1.3.1 - 2019-09-21
- Fix some linking issues when creating executables with native dependencies.
- jpm now runs each test script in a new interpreter.
- Fix an issue that prevent some valid programs from compiling.
- Add
mean
to core. - Abstract types that implement the
:+
,:-
,:*
,:/
,:>
,:==
,:<
,:<=
, 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.
1.3.0 - 2019-09-05
- Add
get-in
,put-in
,update-in
, andfreeze
to core. - Add
jpm run rule
andjpm rules
to jpm to improve utility and discoverability of jpm. - Remove
cook
module and movepath
module to https://github.com/janet-lang/path.git. The functionality incook
is now bundled directly in thejpm
script. - Add
buffer/format
andstring/format
format flagsQ
andq
to print colored and non-colored single-line values, similar toP
andp
. - Change default repl to print long sequences on one line and color stacktraces if color is enabled.
- Add
backmatch
pattern for PEGs. - jpm detects if not in a Developer Command prompt on windows for a better error message.
- jpm install git submodules in dependencies
- Change default fiber stack limit to the maximum value of a 32 bit signed integer.
- Some bug fixes with
jpm
- Fix bugs with pegs.
- Add
os/arch
to get ISA that janet was compiled for - Add color to stacktraces via
(dyn :err-color)
1.2.0 - 2019-08-08
- Add
take
anddrop
functions that are easier to use compared to the existing slice functions. - Add optional default value to
get
. - Add function literal short-hand via
|
reader macro, which maps to theshort-fn
macro. - Add
int?
andnat?
functions to the core. - Add
(dyn :executable)
at top level to get what used to be(process/args 0)
. - Add
:linux
to platforms returned by(os/which)
. - Update jpm to build standalone executables. Use
declare-executable
for this. - Add
use
macro. - Remove
process/args
in favor of(dyn :args)
. - Fix bug with Nanbox implementation allowing users to created custom values of any type with typed array and marshal modules, which was unsafe.
- Add
janet_wrap_number_safe
to API, for converting numbers to Janets where the number could be any 64 bit, user provided bit pattern. Certain NaN values (which a machine will never generate as a result of a floating point operation) are guarded against and converted to a default NaN value.
1.1.0 - 2019-07-08
- Change semantics of
-l
flag to be import rather than dofile. - Fix compiler regression in top level defs with destructuring.
- Add
table/clone
. - Improve
jpm
tool with git and dependency capabilities, as well as better module uninstalls.
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
:native:
pattern inmodule/paths
. - Add
module/expand-path
- Remove
module/*syspath*
andmodule/*headerpath*
in favor of dynamic bindings:syspath
and:headerpath
. - Compiled PEGs can now be marshaled and unmarshaled.
- Change signature to
parser/state
- Add
:until
verb to loop. - Add
:p
flag tofiber/new
. - Add
file/{fdopen,fileno}
functions. - Add
parser/clone
function. - Add optional argument to
parser/where
to set parser byte index. - Add optional
env
argument toall-bindings
andall-dynamics
. - Add scratch memory C API functions for auto-released memory on next gc. Scratch memory differs from normal GCed memory as it can also be freed normally for better performance.
- Add API compatibility checking for modules. This will let native modules not load when the host program is not of a compatible version or configuration.
- Change signature of
os/execute
to be much more flexible.
