Release 0.5.0: C++17

https://www.youtube.com/watch?v=srJ6EWiXOTo

New repository: https://github.com/jthorborg/ape

o New source structure with permanent platform projects
o Most dependencies now included as submodules
o Modular and testable components
o Unit tests

• Build system
• Headers shared between plugin and user scripts, removes stale errors
• Complete rewrite to modern C++
• All manual memory management and leaks removed
• All UI, utility etc. now uses cpl
• Extended platform support, including technical Linux support. See requirements.

Parameters

o Much more precise user controls, with ability to type in precise 64 bit values
o More flexible and extensible format / range options for parameter values
o Enumeration / lists of strings now supported as combo boxes
o Now automatable by host
o 64-bit precision internally

Widgets

o Meters are now per-sample evaluated and properly decaying. Also contains peak markers.

Iteration

o Compatible parameter values preserved
o Hotkeys for all major operations
o True multithreaded compilation across plugins
o Old/new sound blended on swapping instances

Engine

o Optimized and built-in FFT
o Support for streaming audio files to and from disk, optionally resampled
o Audio thread interactions now completely lock free
o Precise transport access and playback state events to the plugin 

Quality of life

o SDKs and libraries now ship included, removed reliance on user development setup
o Plugin callbacks for initialization and reconfigurations now run asynchronously to avoid stutter on audio thread and hiccups on main thread
o Many more checks of resource managements, assertions etc. to make it much more safe
o Working code is serialized into the project as well, instead of referencing a script on disk.
o User is notified mismatched / out-of-date scripts
o Removed nonsensical errors on abandoned save dialogs
o Long operations timed and printed to the console

Plugin GUI

o Resizable
o Redesigned, bit buttons removed in favor of simple icons and hotkeys
o Now completely uses vector graphics instead of bitmaps
o Switched to a tabbed system to increase real estate
o Tabs can be orphaned into separate desktop windows, and redocked back
o Graphics optimized and employs precise redrawing, much faster on OS X using core graphics ren-derer
o Subpixel text rasterization for normal DPI displays
o Removed "fpu exceptions" and "protected buffers" switches. These are now determined by compila-tion mode.

Source code editor

o Externally editing files is now supported, reloading and recompiling whenever the file is saved exter-nally
o Full project and intellisense when working in the source repository for user scripts
o Evaluate source code expressions as "breakpoints"
o Text scaling
o Auto indentation
o Saving a file without extension and determined language appends the default language extension
o Menu option to open "home" (also configurable) scripting directory
o Menu option to create a new file, cloned from the template file
o Menu options for build events (compile, activate, clean, edit externally etc.)
o Default now with a dark theme

New compiler / language: CppApe

o C++ 17 bleeding edge compiler, based on Clang
o Runtime vehicle is libCppJit: Multithreaded, lazy JIT based on LLVM
o User scripts can now include and use other scripts
o Completely revised front end together with safe and idiomatic user API, boiler plate removed
o Access to most of C++ standard library, based on libcxx
o Subset of C standard library available, based on ccore
o Built-in SIMD vectorized math
o DSP primitives, interpolation algorithms
o Type safe and much faster print() family functions
o 32-bit / 64-bit / 80-bit templated math precision, switchable by user in UI
o Typical scientific math constants available as templated constant expressions
o Complete user API documentation here: TODO
o Assertions supported
o RAII and unwind support
o Some exception support
o Globals, static constructors and destructors supported
o Memory mapped and precompiled system headers for compilation speed

Oscilloscope

o Based on Signalizer
o Per-sample source code expression evaluation and graphing
o Color coded inputs / outputs
o User-defined triggering

Bugs

o Console is now thread safe
o Compilation is now thread safe
o Fixed crashes on immediate deserialization
o Many user file bugs fixed

Tcc4APE

o More or less deprecated, still ships in source form but complete support is missing
o Same for syswrap.
