ArkScript Files

Added

• stdlib:
  • list:intersection
  • list:difference
  • sys:version, has the version of the ArkScript VM
  • new macros let*, mut* and set*
• IR inliner, running after the AST lowerer, before the IR optimiser
• new debugger command scopes, printing the last n scopes (default: 5)
• new CLI toggle -f(no-)irinliner to toggle the IR inliner pass (default: On)

Changed

• fix a bug related to recursive closures: once a closure was referenced in its own scope, we couldn't convert it to string or compare it against another closure/itself
• bytecode reader: the length of code segments is counted in instructions, not bytes
• the compiler can track the origin of an IR block, in preparation for inlining
• POP_SCOPE can take an argument to have a mode: by default, 0, only pop the current scope ; if 1, materialise the top of the stack if it's a reference
• the debugger does not trace the instructions of the code being run inside it (only instructions from the script are traced)
• the AST lowerer checks for (breakpoint) at the end of begin nodes to determine if a node is unused or terminal
