ArkScript v4.0.0-rc5

Added

• more tests for the io builtins
• added lines and code coloration in the error context
• new dependency: fmtlib
• added the padding/instruction/argumentation values when displaying instructions in the bytecode reader
• $repr macro to get a string representation of a given node
• added boost-ext/ut to write unit tests in C++
• basic ArkScript code formatter, available through the CLI: arkscript -f|--format
• comments are now tracked in the AST and attached to the nearest node below them
• VM::forceReloadPlugins, to be used by the REPL to force reload the plugins and be sure that their symbols are all define
• added help, save (save history to disk), history (print history), reset (reset vm and code) commands to the REPL
• REPL can now show when a code block isn't terminated (prompt changes from > to :)
• more controls available inside the REPL

Changed

• instructions are on 4 bytes: 1 byte for the instruction, 1 byte of padding, 2 bytes for an immediate argument
• enhanced the bytecode reader and its command line interface
• added the padding/instruction/argumentation values when displaying instructions in the bytecode reader
• fixed underline bug in the error context
• the str:format functions now expects strings following this syntax: https://fmt.dev/latest/syntax.html
• more documentation about the compiler implementation
• more documentation about the virtual machine
• closures can be now be compared field per field: (= closure1 closure2) will work only if they have the same fields (name) and if the values match
• macros are now defined like ($ name value) / ($ name (args args args) body) / ($if cond then else)
• upgraded from C++17 to C++20
• new parser, new syntax for imports: (import package.sub.file)
• allow nodes to be empty when dumping the AST to JSON
• macros can be declared inside a begin block within a cond macro and used in the scope surrounding the cond macro
• arkscript --version and arkscript --help now output ArkScript version with the commit hash
• void Value::toString(std::ostream&, VM&) now becomes std::string Value::toString(VM&)
• removed Node::operator<< to replace it with Node::debugPrint

Removed

• removed unused NodeType::Closure
• removing the custom string, replacing it with std::string (the format engine of the custom string had a lot of memory leaks)
• Utils::digPlaces and Utils::decPlaces got removed as they were no longer needed
• removed deprecated code (list:removeAt, ark executable now replaced by arkscript)
• removed VM::getUserPointer and VM::setUserPointer
• removed ARK_PROFILER_COUNT define
