Minimal C++ library with Lua bindings and console. Write your LV2 plugins and gui's in C++. The Widgets library can be used in any project, it is not directly tied to LV2 UI.

Heavy Development: API's will break from time to time until the core system is ready. Plugin/UI templates are largely unchanged, but could radically change in terms of API.

LVTK is intended to be used as a subproject by LV2 plugin and UI developers. Docs, Lua Bindings, the Widgets Demo, Lilv wrapper tests, and the lvtk.lv2 plugins are disabled by default so plugin developers don't have to worry about it. If packaging, these items will need enabled manually via a meson native/cross file or the command line. see meson_options.txt

Status Legend

• Finished And ready to go.
• Working but not finished in terms of fine details and final type names and signatures.
• Close to working, functionality partially implemented.
• Started some RND, highly experimental.

To build and install, run

$ meson setup build
$ ninja -C build
$ ninja -C test
$ ninja install # optional

For MSVC on Windows, use:

meson setup build
meson compile -C build

Go to the build directory and run it:

cd build
./lvtk-demo

Double-clickable Mac apps can be found somewhere in the build directory. The following command will list them all out.

# From the source top dir.
find build -name "LVTK*.app"
