ArkScript v3.0.12

Change log

The biggest release ever!

3.0.12

Added

• using a macro to define the default filename (when none is given, eg when loading bytecode files or from the REPL)
• PLUGIN <const id> instruction to load plugin dynamically and not when the VM boots up
• updated search paths for (import "lib.ark"), looking in ./, lib/std/ and lib/
• added a case to display NOT instructions in the bytecode reader
• T& as<T>() in usertype
• enhanced error message when calling a non-function object
• eliminating unused global scope variables in the compiler
• adding a new feature enabled by default: FeatureRemoveUnusedVars (not enabled for the REPL for obvious reasons)
• added replxx as a submodule
• added custom destructor to the user type, called when a scope is destroyed and when we use (del obj)
• added a GVL (global virtual machine lock) to be able to use the VM in a multithreaded context
• dockerfile + specific github action to build and push stable and nightly docker images, thanks to @yardenshoham
• added guards to the bytecode reader to stop reading if we're missing an entry point; now telling the user about it

Changed

• updated the string module to benefit from the new format member function
• updated the logger to remove fmt/format
• changed the argument order for Ark::State
• renamed the cache directory __arkscript__
• operator @ can now handle negative indexes to get elements from the end of the given container
• the standard library is now in another repository
• moved the modules to lib/ext
• the value of CODE_SEGMENT_START is again 0x03 (because we removed the plugin table)
• renamed isDir? to dir? for consistency
• the lexer is no longer using regexes but a char after char method
• an ArkScript program is no longer a single bloc, but can be composed of multiple bloc, thus we don't need to use a single big {} or (begin) bloc for all the program
• enhancing lexer and parser error messages
• else clause in if constructions is now optional
• updating error messages in the VM
• updated the repl to add auto completion, coloration and persistance by @PierrePharel
• moving the parser, lexer and AST node to Compiler/ from Parser/
• better import error messages at parsing
• format can now handle any value type
• updated the tests to use the new standard library, and testing every VM instruction and builtins (we didn't test everything before, this way we can be sure we don't break anything in the VM after each update)
• renaming builtins to add a namespace to them (math:, sys:, str:, list: and such)
• firstOf, tailOf and headOf now returns [] or "" instead of nil when they have nothing to do
• adding a brand new scoping system, lighter, more powerful
• str:find now returns the index where the substring was found
• str:removeAt was fixed to throw an error when the index is strictly equal to the length of the string (can not work since accessing elements in string is 0-index based)

Removed

• removed fmt/format from our dependencies
• PLUGIN_TABLE was removed to use the PLUGIN instruction
• not_() from usertype
• removed Parser/Utf8Converter

ArkScript v3.0.11

Change Log

3.0.11

Added

• member function resolve(Args&& args...) to Value, callable by plugins to resolve the value of a function called with specific arguments given by the plugin
• (fill qu value) create a list of qu values
• (setListAt list at new-value) modify a list in place and return the new list value
• adding UTF-8 support in programs (experimental)
• more benchmarks
• on error, the VM now display the value of each variable in the current scope
• added thirdparty/madureira/String, to replace std::string in Ark::internal::Value which was heavy and slower than the new implementation
• minimizing the size of the usertype

Changed

• UserType does not need to be given a manually defined type id but relies on typeid(T)
• performance boost of the VM by using pointers to avoid unecessary copies
• renaming isNaN to NaN?, isInf to Inf? for uniformisation (see empty?, nil?)
• renaming CLI feature options:
  • -ffunction-arity-check becomes -ffac, same for the -fno- version
  • -fauthorize-invalid-token-after-paren becomes -faitap, some for the -fno- version
• improving compiler performances by using const ref when passing nodes around
• renaming the FFI "builtins" because it's not a FFI but a set of functions using the VM API
• the VM should display a backtrace even if an unknown error occured
• transforming inline code from the vm into not inline code when possible to speed compilation, using macros instead of inline functions
• smaller value class
• smaller vm frames
• forked madureira/String and modified it for the needs of the project, added it as a submodule
• removed the VM pointer from the value class to make it lighter, now the VM is sending a pointer of itself to the C procedures
• removed const and type from value, now using a uint8_t to store those informations

Removed

• removed NFT from the internal API to rely only on the value type

ArkScript v3.0.10

3.0.10

Added

• adding sort to sort a list
• added \t, \n, \v and \r escape codes (available in strings only)
• adding listFiles which returns a list of paths (strings)
• adding (makeDir path) and (removeFiles ...)
• added (filter func list) in lib/Functional/Functional.ark
• adding puts. Does the same thing as print but doesn't print a newline character
• added a msgpack module by @PierrePharel
• added a user type (to be defined in C++)
• adding a not operator
• adding an http module by @SuperFola

Changed

• updated output of tests with number of passed tests
• updated REPL so that it doesn't try to compile blank lines or comments, by @rstefanic
• the option -d|--debug is now repeatable, to set a debug level. Can go from 1 (compilation information) to 3 (a lot of information).
• better precision when using (time)
• better tests presentation
• moved the modules to https://github.com/ArkScript-lang/modules

ArkScript v3.0.9

Added

• fixing segfault when the VM receives an empty code page (generated from an empty block)
• (print (fun () ())) will now print Function @ 1 instead of just its page addr, 1
• (if true () ()) now returns nil (can be generalized to () -> nil)
• anonymous functions are now available ; eg: ((fun () (print "a")))
• added forEach in library
• added -c|--compile option to the CLI so that we can only compile an ArkScript file instead of compiling and running it, by @DontBelieveMe
• added min and max in lib/Math/Arithmetic.ark, by @FrenchMasterSword
• added reduce in lib/Functional/Reduce.ark, by @FrenchMasterSword
• added product in lib/List/Product.ark, by @FrenchMasterSword

Changed

• a quoted code (defered evaluation) isn't capturing anymore surrounding variables' values, thus increasing greatly performances
• lists are printed like ["string" 1 true] now, instead of ( string 1 true )
• updated zip so that it can work with lists of different sizes, by @FrenchMasterSword
• better cyclic includes detection

• the internal API used to compare values has been updated to be much shorter
• the REPL can take into account the lib directory, by @rstefanic
• isNaN and isInf should work on any type but return false if they aren't numbers
• replacing Ark with ArkScript in source code and files (Ark being the shortname for ArkScript, as JS is the shortname for Javascript)

Shipping with the compiled modules this time
