Change log

WARNING: to get the source version

• correct polyphonic DSP detection in FaustPolyEngine
• faust2ios now creates a self-contained project
• correct -omp and -sch code generation with 'soundfile' primitive

• allow some foreign math functions in the Interp backend
• A.Graef fix for compilation problems with gcc 8.1+ and Qt 5.10+
• CoreAudio targets working on OS X 10.14 (correct ask the user for audio input access)

Change log

• new cmake based build system.

• new ‘soundfile’ primitive with support in several faust2xx scripts.

• better error checking with delay parameter.

• add -effect auto/effect.dsp parameter in several faust2xx scripts.

• introduction of a new statement allowing to declare definition-related metadata: declare foo author "me";

• rework libfaust API.

• adds support for function level metadata. In order to facilitate cooperation between authors of Faust libraries, in particular the fact that multiple authors can contribute to the same library, a new declare statement is introduced: declare <function> <key> "<value>";. It allows to declare for each function of a library its own metadata, for example its author, its copyrights, its license, etc. Metadata for a function can be anywhere in the file, but we recommend placing it just before the function definition.

• integration of SAM (SHARC Audio Module) Architecture contributed by Analog Device and Moforte.

• adds a new option: -scn <name> or --super-class-name <name>, to change the name 'dsp' of the super class.

• simplification of some degenerated recursive expressions. Degenerated recursions like: (!:2)~_ are simplified (in this case replace by 2).

• simplify signals during propagations.

• add multicast address and bundle handing in OSC architecture.

• add AudioWorklet handling in WebAudio architectures.

• rework Bela architecture.

• new semantic for remainder (%) operator. The % operator is now automatically promoted to fmod when one of the two arguments is a float expression.
  TypeExtended annotation extended with a second parameter to control causality check. When this parameter is true, TypeAnnotation rejects non-causal delays. When this parameter is false, TypeAnnotation accepts non-causal delays. TypeAnnotation is called twice: before and after normalization/optimization. During the first call, the parameter is usually set to false (unless the -lcc/--local-causality-check option is passed to the compiler) in order to accept local non-causal delays that can disappear after optimization. On the second call, this parameter is always set to true in order to reject remaining non-causal delays.

• adds new simplification rule: 0-x ==> -1*x.

• fix concatenation of delay lines. The expressions (s@n)@m and s@(n+m) are equivalent only when n is constant.

• add a new libfaustmachine library containing a separated interpreter.

• new -os option (one sample code generation).

• improvement of automatic tests (compiler and architectures).

• numerous bug fixes in the compiler and architectures.
