lvtk's Introduction

LVTK3

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.

Minimal by Design

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

Widgets

Widget	Status	Purpose
`lvtk.Widget`	Working	Base for all widgets
`lvtk.Button`	Close	Base for most button types
`lvtk.TextButton`	Close	A regular button that shows text
`lvtk.Label`	-	A text display Widget
`lvtk.Entry`	Started	A basic single-line text entry
`lvtk.Ranged`	Working	Base for Widgets with a ralue range.
`lvtk.Slider`	Close	A basic single-value slider control
`lvtk.Dial`	Started	A basic single-value Dial (or Knob) control
`lvtk.Embed`	Started	Embed OS Native Windows/Views

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.

Building

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
meson test -C build

Widgets Demo

Linux & Windows

Go to the build directory and run it:

cd build
./lvtk-demo

macOS

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"

Compilation error on Linux with lv2 1.17.0

While trying to recompile the lvtk-git AUR package with lv2 1.17.0 (compiled from the lv2-git AUR package), I get the following compilation error:

Volume Smoothing Doesn't Seem Right

Volume control smoothing doesn't seem to be working correctly in the Volume example plugin

Finish DynManifest Impl.

Needs to deal with features, and also return non-zero where appropriate.

Discovery With LV2_Lib_Descriptor

Plugin author's should be able to register as an LV2 Lib if desired.

Refine example code (vectorization, zipper noise)

lvtk/plugins/volume.cpp

Lines 27 to 28 in 0a41015

 for (uint32_t f = 0; f < nframes; ++f) 

 for (uint32_t c = 0; c < 2; ++c)

Curious, can a compiler vectorize this? I'd expect that these two lines need to be swapped since
each channel is usually at a different base address.

Since examples are copied often and used as basis, it would not hurt to showcase parameter interpolation to prevent zipper noise. If you want to keep it simple perhaps add a comment "a real work plugin would interpolate gain..".

Qt4 UI - Example GUI

Doesn't require a new plugin. Make a qt4 gui for one of the existing example plugins.

STL Compatible Iterators

Make iterators compatible with std c++ templating.

Atom Vector (iter only?)
Atom Sequence
Atom Object (properties)

Confusing mix of buffersize data members

lvtk/lvtk/ext/bufsize.hpp

Lines 56 to 62 in a624b10

 bool bounded = false; /**< <http://lv2plug.in/ns/ext/buf-size#boundedBlockLength> */ 

 bool fixed = false; /**< <http://lv2plug.in/ns/ext/buf-size#fixedBlockLength> */ 

 bool power_of_two = false; /**< <http://lv2plug.in/ns/ext/buf-size#powerOf2BlockLength> */ 

 uint32_t min = 0; /**< <http://lv2plug.in/ns/ext/buf-size#minBlockLength> */ 

 uint32_t max = 0; /**< <http://lv2plug.in/ns/ext/buf-size#maxBlockLength> */ 

 uint32_t nominal = 0; /**< <http://lv2plug.in/ns/ext/buf-size#nominalBlockLength> */ 

 uint32_t sequence_size = 0; /**< <http://lv2plug.in/ns/ext/buf-size#sequenceSize> */

The first three are features that a plugin may require from a host. A host checks if a plugin needs any of these features (not the other way around), and they have to be specified in the .ttl.

"sequence size" is a port-property of an atom port. Also specified by the plugin. It is not an instance property set by the host.

min/max/nominal are fine. I suggest to use std::optional to be able to tell if a host announces those values (zero is a valid minimum).

Move libpaq/ttl2c To Its Own Project(s)

This will be part of removing things that aren't implementing LV2 boilerplate code.

Plugin examples at this point should probably not rely on ttl2c for header generation.
libpaq should either be renamed and released with the new name, or continue to be compiled in with ttl2c. The reason here is debian proper already has libpaq-dev (from lv2-c++-tools)

Qt4 UI - Possible Memory Leakage

It can leak memory if calling code calls set_widget (QWidget*) more than once.

2.0.0-rc1 doesn't install lvtk-plugin-2 and beatslash fails to compile

Do you know what is wrong? Why 2.0.0-rc1 doesn't install lvtk-plugin-2 any more?

Remove LVTK_STATIC_ARGS Experimental Code

This was an attempt to use static Args and UIArgs during instantiation so that Instance subclasses don't have to worry about passing a param to it's ctor. Decided wasn't really worth the effort.

This code should be removed before 2.0 to avoid confusion in the Docs and Impl. of new plugins and UIs

Supporting this compiler will be a good idea. anticipating mac osx compatibility for new OSX versions 10.9 and up probably.

Convert Host Side Features to FeatureData<D> template

Should convert utility classes to FeatureData where possible. This is for consistency's sake.

GTK2 is EOL

Hi! I maintain this software as a package for Arch Linux, as it is used to build plugins from it.
GTK2 is now EOL and distributions will start to phase it out of existence.

Is it possible to port this software to use another UI framework instead?
Popular choices for plugins seem to be pugl, JUCE and DPF.

GTK and Qt are known to cause trouble with host software and some of the hosts do not allow loading plugins based on these UI frameworks anymore.

Example plugin validation fails

Don't add UI turtle info when not building the VolumeUI

The plugin lacks required version information.
It announces a GUI that doesn't exist, even though configuration detects that it's n/a:
