Calvin Rose f709d7eb40 Add module/add-paths 
This should make it much easier to make custom DSLs work
well with the import system. No need to mess about with import paths,
 things will just work.

Changelog

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

Unreleased

  • 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 module/add-paths
  • 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 nan?
  • 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.

  • 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.

  • Make pp configurable with dynamic binding :pretty-format.
  • Remove the meta function.
  • Add with-dyns for blocks with dynamic bindings assigned.
