janet/CHANGELOG.md

# Changelog
All notable changes to this project will be documented in this file.

## 1.18.0 - 2021-10-10
- Allow `ev/cancel` to work on already scheduled fibers.
- Fix bugs with ev/ module.
- Add optional `base` argument to scan-number
- Add `-i` flag to janet binary to make it easier to run image files from the command line
- Remove `thread/` module.
- Add `(number ...)` pattern to peg for more efficient number parsing using Janet's
  scan-number function without immediate string creation.

## 1.17.2 - 2021-09-18
- Remove include of windows.h from janet.h. This caused issues on certain projects.
- Fix formatting in doc-format to better handle special characters in signatures.
- Fix some marshalling bugs.
- Add optional Makefile target to install jpm as well.
- Supervisor channels in threads will no longer include a wasteful copy of the fiber in every
  message across a thread.
- Allow passing a closure to `ev/thread` as well as a whole fiber.
- Allow passing a closure directly to `ev/go` to spawn fibers on the event loop.

## 1.17.1 - 2021-08-29
- Fix docstring typos
- Add `make install-jpm-git` to make jpm co-install simpler if using the Makefile.
- Fix bugs with starting ev/threads and fiber marshaling.

## 1.17.0 - 2021-08-21
- Add the `-E` flag for one-liners with the `short-fn` syntax for argument passing.
- Add support for threaded abstract types. Threaded abstract types can easily be shared between threads.
- Deprecate the `thread` library. Use threaded channels and ev instead.
- Channels can now be marshalled.
- Add the ability to close channels with `ev/chan-close` (or `:close`).
- Add threaded channels with `ev/thread-chan`.
- Add `JANET_FN` and `JANET_REG` macros to more easily define C functions that export their source mapping information.
- Add `janet_interpreter_interupt` and `janet_loop1_interrupt` to interrupt the interpreter while running.
- Add `table/clear`
- Add build option to disable the threading library without disabling all threads.
- Remove JPM from the main Janet distribution. Instead, JPM must be installed
  separately like any other package.
- Fix issue with `ev/go` when called with an initial value and supervisor.
- Add the C API functions `janet_vm_save` and `janet_vm_load` to allow
saving and restoring the entire VM state.

## 1.16.1 - 2021-06-09
- Add `maclintf` - a utility for adding linting messages when inside macros.
- Print source code of offending line on compiler warnings and errors.
- Fix some issues with linting and re-add missing `make docs`.
- Allow controlling linting with dynamic bindings `:lint-warn`, `:lint-error`, and `:lint-levels`.
- Add `-w` and `-x` command line flags to the `janet` binary to set linting thresholds.
  linting thresholds are as follows:
    - :none - will never be trigger.
    - :relaxed - will only trigger on `:relaxed` lints.
    - :normal - will trigger on `:relaxed` and `:normal` lints.
    - :strict - will trigger on `:strict`, `:normal`, and `:relaxed` lints. This will catch the most issues
      but can be distracting.

## 1.16.0 - 2021-05-30
- Add color documentation to the `doc` macro - enable/disable with `(dyn :doc-color)`.
- Remove simpler HTML docs from distribution - use website or built-in documentation instead.
- Add compiler warnings and deprecation levels.
- Add `as-macro` to make using macros within quasiquote easier to do hygienically.
- Expose `JANET_OUT_OF_MEMORY` as part of the Janet API.
- Add `native-deps` option to `declare-native` in `jpm`. This lets native libraries link to other
  native libraries when building with jpm.
- Remove the `tarray` module. The functionality of typed arrays will be moved to an external module
  that can be installed via `jpm`.
- Add `from-pairs` to core.
- Add `JPM_OS_WHICH` environment variable to jpm to allow changing auto-detection behavior.
- The flychecker will consider any top-level calls of functions that start with `define-` to
  be safe to execute and execute them. This allows certain patterns (like spork/path) to be
  better processed by the flychecker.

## 1.15.5 - 2021-04-25
- Add `declare-headers` to jpm.
- Fix error using unix pipes on BSDs.
- Support .cc and .cxx extensions in `jpm` for C++ code.
- Change networking code to not create as many HUP errors.
- Add `net/shutdown` to close sockets in one direction without hang ups.
- Update code for printing the debug repl

## 1.15.4 - 2021-03-16
- Increase default nesting depth of pretty printing to `JANET_RECURSION_GUARD`
- Update meson.build
- Add option to automatically add shebang line in installed scripts with `jpm`.
- Add `partition-by` and `group-by` to the core.
- Sort keys in pretty printing output.

## 1.15.3 - 2021-02-28
- Fix a fiber bug that occured in deeply nested fibers
- Add `unref` combinator to pegs.
- Small docstring changes.

## 1.15.2 - 2021-02-15
- Fix bug in windows version of `os/spawn` and `os/execute` with setting environment variables.
- Fix documentation typos.
- Fix peg integer reading combinators when used with capture tags.

## 1.15.0 - 2021-02-08

- Clean up output of flychecking to be the same as the repl.
- Change behavior of `debug/stacktrace` with a nil error value.
- Add optional argument to `parser/produce`.
- Add `no-core` option to creating standalone binaries to make execution faster.
- Fix bug where a buffer overflow could be confused with an out of memory error.
- Change error output to `file:line:column: message`. Column is in bytes - tabs
  are considered to have width 1 (instead of 8).

## 1.14.2 - 2021-01-23
- Allow `JANET_PROFILE` env variable to load a profile before loading the repl.
- Update `tracev` macro to allow `def` and `var` inside to work as expected.
- Use `(dyn :peg-grammar)` for passing a default grammar to `peg/compile` instead of loading
  `default-peg-grammar` directly from the root environment.
- Add `ev/thread` for combining threading with the event loop.
- Add `ev/do-thread` to make `ev/thread` easier to use.
- Automatically set supervisor channel in `net/accept-loop` and `net/server` correctly.

## 1.14.1 - 2021-01-18
- Add `doc-of` for reverse documentation lookup.
- Add `ev/give-supervsior` to send a message to the supervising channel.
- Add `ev/gather` and `chan` argument to `ev/go`. This new argument allows "supervisor channels"
  for fibers to enable structured concurrency.
- Make `-k` flag work on stdin if no files are given.
- Add `flycheck` function to core.
- Make `backmatch` and `backref` more expressive in pegs.
- Fix buggy `string/split`.
- Add `fiber/last-value` to get the value that was last yielded, errored, or signaled
  by a fiber.
- Remove `:generate` verb from `loop` macros. Instead, use the `:in` verb
  which will now work on fibers as well as other data structures.
- Define `next`, `get`, and `in` for fibers. This lets
  `each`, `map`, and similar iteration macros can now iterate over fibers.
- Remove macro `eachy`, which can be replaced by `each`.
- Add `dflt` argument to find-index.
- Deprecate `file/popen` in favor of `os/spawn`.
- Add `:all` keyword to `ev/read` and `net/read` to make them more like `file/read`. However, we
  do not provide any `:line` option as that requires buffering.
- Change repl behavior to make Ctrl-C raise SIGINT on posix. The old behavior for Ctrl-C,
  to clear the current line buffer, has been moved to Ctrl-Q.
- 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 `/`
  are now unambiguously importing from the syspath, instead of checking both the syspath and
  the project root. This is backwards incompatible and dependencies should be updated for this.
- Change hash function for numbers.
- Improve error handling of `dofile`.
- Bug fixes in networking and subprocess code.
- Use markdown formatting in more places for docstrings.

## 1.13.1 - 2020-12-13
- Pretty printing a table with a prototype will look for `:_name` instead of `:name`
  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.
- Argument to `(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 `merge-module` to core.
- During installation and release, merge janetconf.h into janet.h for easier install.
- Add `upscope` special form.
- `os/execute` and `os/spawn` can take streams for redirecting IO.
- Add `:parser` and `:read` parameters to `run-context`.
- Add `os/open` if ev is enabled.
- Add `os/pipe` if ev is enabled.
- Add `janet_thread_current(void)` to C API
- Add integer parsing forms to pegs. This makes parsing many binary protocols easier.
- Lots of updates to networking code - now can use epoll (or poll) on linux and IOCP on windows.
- 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` and `net/listen`. These functions break down `net/server` into it's essential parts
  and are more flexible. They also allow further improvements to these utility functions.
- Various small bug fixes.

## 1.12.2 - 2020-09-20
- Add janet\_try and janet\_restore to C API.
- Fix `os/execute` regression on windows.

- Add `janet_getjfile` to C API.
- Allow redirection of stdin, stdout, and stderr by passing keywords in the env table in `os/spawn` and `os/execute`.
- Add `os/spawn` to get a core/process back instead of an exit code as in `os/execute`.
  When called like this, `os/execute` returns immediately.
- Add `:x` flag to os/execute to raise error when exit code is non-zero.
- Don't run `main` when flychecking.
- Add `:n` flag to `file/open` to raise an error if file cannot be opened.
- Fix import macro to not try and coerce everything to a string.
- Allow passing a second argument to `disasm`.
- Add `cancel`. Resumes a fiber but makes it immediately error at the yield point.
- Allow multi-line paste into built in repl.
- Add `(curenv)`.
- Change `net/read`, `net/chunk`, and `net/write` to raise errors in the case of failures.

  to raise errors or other signals.
- Update meson build script to fix bug on Debian's version of meson
- Add `xprint`, `xprin`, `xprintf`, and `xprinf`.
- `net/write` now raises an error message if write fails.

- Add `:no-compile` to `create-executable` option for jpm.
- Fix bug with the `trace` function.
- Add `:h`, `:a`, and `:c` flags to `thread/new` for creating new kinds of threads.

## 1.8.0 - 2020-03-29
- Add `reduce2`, `accumulate`, and `accumulate2`.
- Add lockfiles to `jpm` via `jpm make-lockfile` and `jpm load-lockfile`.
- Add `os/realpath` (Not supported on windows).
- Add `os/chmod`.
- Add `chr` macro.
- Allow `_` in the `match` macro to match anything without creating a binding
  or doing unification. Also change behavior of matching nil.
- Add `:range-to` and `:down-to` verbs in the `loop` macro.
- Fix `and` and `or` macros returning nil instead of false in some cases.
- Allow matching successfully against nil values in the `match` macro.
- Improve `janet_formatc` and `janet_panicf` formatters to be more like `string/format`.

## 1.7.0 - 2020-02-01
- Remove `file/fileno` and `file/fdopen`.
- Remove `==`, `not==`, `order<`, `order>`, `order<=`, and `order>=`. 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.
- Add `var-`
- Add `module/add-paths`
- Add `file/temp`
- Add `mod` function to core.
- Small bug fixes
- Allow signaling from C functions (yielding) via janet\_signalv. This
  makes it easy to write C functions that work with event loops, such as
  in libuv or embedded in a game.
- Add '%j' formatting option to the format family of functions.
- Add `defer`
- Add `assert`
- Add `when-with`
- Add `if-with`
- Add completion to the default repl based on currently defined bindings. Also generally improve
  the repl keybindings.
- Add `eachk`
- Add `eachp`
- Improve functionality of the `next` function. `next` now works on many different
  types, not just tables and structs. This allows for more generic data processing.
- Fix thread module issue where sometimes decoding a message failed.
- Fix segfault regression when macros are called with bad arity.

## 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` and `eprinf` to be have like `printf` and `eprintf`. The latter two functions
  now including a trailing newline, like the other print functions.

- Add `janet_in` to C API.
- Add `truthy?`
- Add `os/environ`
- Add `buffer/fill` and `array/fill`
- Add `array/new-filled`
- Use `(doc)` with no arguments to see available bindings and dynamic bindings.
- `jpm` will use `CC` and `AR` 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` to `jpm`.
- Add several default patterns, like `:d` and `:s+`, to PEGs.
- Update `jpm` path settings to make using `jpm` 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`, and `math/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`
  and `math/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` and `eprin` 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`, and `freeze` to core.
- Add `jpm run rule` and `jpm rules` to jpm to improve utility and discoverability of jpm.
- Remove `cook` module and move `path` module to https://github.com/janet-lang/path.git.
  The functionality in `cook` is now bundled directly in the `jpm` script.
- Add `buffer/format` and `string/format` format flags `Q` and `q` to print colored and
  non-colored single-line values, similar to `P` and `p`.
- 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` and `drop` 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 the
  `short-fn` macro.
- Add `int?` and `nat?` 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` and `JANET_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
  in `module/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 in `module/paths`.
- Add `module/expand-path`
- Remove `module/*syspath*` and `module/*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 to `fiber/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 to `all-bindings` and `all-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.

## 0.6.0 - 2019-05-29
- `file/close` returns exit code when closing file opened with `file/popen`.
- Add `os/rename`
- Update windows installer to include tools like `jpm`.
- Add `jpm` tool for building and managing projects.
- Change interface to `cook` tool.
- Add optional filters to `module/paths` to further refine import methods.
- Add keyword arguments via `&keys` in parameter list.
- Add `-k` flag for flychecking source.
- Change signature to `compile` function.
- Add `module/loaders` for custom loading functions.
- Add external unification to `match` macro.
- Add static library to main build.
- Add `janet/*headerpath*` and change location of installed headers.
- Let `partition` take strings.
- Haiku OS support
- Add `string/trim`, `string/trimr`, and `string/triml`.
- Add `dofile` function.
- Numbers require at least 1 significant digit.
- `file/read` will return nil on end of file.
- Fix various bugs.

## 0.5.0 - 2019-05-09
- Fix some bugs with buffers.
- Add `trace` and `untrace` to the core library.
- Add `string/has-prefix?` and `string/has-suffix?` to string module.
- Add simple debugger to repl that activates on errors or debug signal
- Remove `*env*` and `*doc-width*`.
- Add `fiber/getenv`, `fiber/setenv`, and `dyn`, and `setdyn`.
- Add support for dynamic bindings (via the `dyn` and `setdyn` functions).
- Change signatures of some functions like `eval` which no longer takes
  an optional environment.
- Add printf function
- Make `pp` configurable with dynamic binding `:pretty-format`.
- Remove the `meta` function.
- Add `with-dyns` for blocks with dynamic bindings assigned.
- Allow leading and trailing newlines in backtick-delimited string (long strings).
  These newlines will not be included in the actual string value.

## 0.4.1 - 2019-04-14
- Squash some bugs
- Peg patterns can now make captures in any position in a grammar.
- Add color to repl output
- Add array/remove function
- Add meson build support
- Add int module for int types
- Add meson build option
- Add (break) special form and improve loop macro
- Allow abstract types to specify custom tostring method
- Extend C API for marshalling abstract types and other values
- Add functions to `os` module.

## 0.4.0 - 2019-03-08
- Fix a number of smaller bugs
- Added :export option to import and require
- Added typed arrays
- Remove `callable?`.
- Remove `tuple/append` and `tuple/prepend`, which may have seemed like `O(1)`
  operations. Instead, use the `splice` special to extend tuples.
- Add `-m` flag to main client to allow specifying where to load
  system modules from.
- Add `-c` flag to main client to allow compiling Janet modules to images.
- Add `string/format` and `buffer/format`.
- Remove `string/pretty` and `string/number`.
- `make-image` function creates pre compiled images for janet. These images
  link to the core library. They can be loaded via require or manually via
  `load-image`.
- Add bracketed tuples as tuple constructor.
- Add partition function to core library.
- Pre-compile core library into an image for faster startup.
- Add methods to parser values that mirror the api.
- Add janet\_getmethod to CAPI for easier use of method like syntax.
- Add get/set to abstract types to allow them to behave more
  like objects with methods.
- Add parser/insert to modify parser state programmatically
- Add debug/stacktrace for easy, pretty stacktraces
- Remove the status-pp function
- Update API to run-context to be much more sane
- Add :lflags option to cook/make-native
- Disallow NaNs as table or struct keys
- Update module resolution paths and format

## 0.3.0 - 2019-01-26
