Changelog

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

Unreleased

• Add with-vars macro.
• Add the quickbin command to jpm.
• Create shell.c when making the amlagamated 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 flyching 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 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 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.

• Fix a number of smaller bugs
• Added :export option to import and require
• Added typed arrays
• Remove callable?.

• Add -c flag to main client to allow compiling Janet modules to images.
