The most notable features of this new release are:

  • The introduction of FFI allowing buzz to call C functions very easily (see this example using SDL).
  • object generic types
  • Type values
  • The new var keyword

Here is the full changelog:

Added

  • FFI (#109)
    • Uses MIR to generate wrappers around imported functions and to generate getters and setters to struct fields
    • New zdef statement to declare and bind foreign functions and struct using zig code
    • New ffi std lib
    • When you need a pointer to something you can use the Buffer std lib object. Added:
      • Buffer.writeZ, Buffer.readZ, Buffer.writeStruct, Buffer.readStruct
      • Buffer.ptr, Buffer.len
  • New (fancy) error reporter (#153)
  • Errors have now an associated code
  • os.sleep
  • First class types (#21)
    • Type can be passed around as values like so: <str>
    • New typeof operator returns type of any value: typeof "hello" -> <str>
  • Delimiters for non-standard identifiers (#138)
  • Collectors (#2): if an object has a fun collect() > void method, it will be called before an instance of this object is collected by the garbage collector
  • Helpers around ud
    • std.toUd, returns userdata from an int or float
    • bz_valueToObjUserData
    • bz_getUserDataPtr
    • Buffer.readUserData, Buffer.writeUserData
  • std.serialize takes any buzz value and return a serializable version of it (objects become maps, etc.) provided the data is has no circular reference and does not contain not serializable values (functions, fibers, etc.)
  • UTF8 helpers: str.utf8Len, str.utf8Codepoints, str.utf8Valid (#39)
  • New integer literal for single chars: 'A' == 65 (#172)
  • Compiler will warn you when a local or global is never used or when an expression value is discarded. To silence those warnings you can use the _ = <expression> or name the local/global _.
  • std.currentFiber, fiber.isMain (#162)
  • map.sort, map.forEach, map.map, map.filter, map.reduce, map.diff, map.intersect, map.clone (#110)
  • list.clone (#110)
  • Number literals can embed _: 1_000_000.300_245 (#163)
  • Type can be inferred when declaring a variable/constant with the var or const keyword: var something = "hello" (#194)
  • Objects can have generic types (#82)
  • Draft of the testing std lib (#129)
  • File.isTTY
  • fs.exists
  • Functions annotated with a comment of the form || @hot will always be JIT compiled

Changed

  • json lib is renamed serialize
  • Json now returns a Boxed object (which can be reused in other contexts than JSON)
  • Identifiers can now have _ since pattern delimiters have changed
  • Changed pattern delimiters to $"..." (#165)
  • list.append does not return the appended value anymore
  • Generic types syntax changed from myFunction(<K,V>, ...) to myFunction::<K,V>(...)
  • Nullable object fields and nullable variables have a null initial value if none is provided
  • Migrated to pcre2 which is now a submodule built by build.zig
  • Mimalloc is now a submodule built by build.zig

Fixed

  • Some bugs any
  • Runtime error stack trace was wrong
  • Local name checking failed in some instances
  • Compiler would not force you to give variables an initial value
  • Compiler would crash after raising some errors
  • Float operation were sometimes wrong
  • Catch clause were sometimes not reached in a JIT compiled function
  • Stacktraces of errors reported from within a fiber were wrong
  • catch (any error) was not considered as catching all possible errors by the compiler
  • Full GC sweep were never triggered
