Check whether a given LV2 plugin is up to the specification
An LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.
Run it as part of your continuous integration pipeline together with lv2/sord_validate to reduce the likelihood of shipping plugins with major flaws in order to prevent unsatisfied users.
Note: This is an early release, if you happen to find false-positive warnings when using this tool, please report back, so it can be fixed.
Unstable (nightly) release
Bugs and feature requests
lv2lint can optionally test your plugin URIs for existence. If you want that, you need to enable it at compile time (-Donline-tests=true) and link to libcurl. You will also need to enable it at run-time (-o), e.g. double-opt-in.
lv2lint can optionally test your plugin symbol visibility and link dependencies. If you want that, you need to enable it at compile time (-Delf-tests=true) and link to libelf.
Build / install
git clone https://git.open-music-kontrollers.ch/lv2/lv2lint cd lv2lint meson -Donline-tests=true -Delf-tests=true build cd build ninja sudo ninja install

- elf-tests (check shared object link symbols and dependencies, default=off)
Information about the command line arguments are described in the man page:
man 1 lv2lint
An acceptable plugin SHOULD pass without triggering any fails, this is also the default configuration:
A good plugin SHOULD pass without triggering any warnings:
lv2lint -Ewarn http://lv2plug.in/plugins/eg-scope#Stereo
A perfect plugin SHOULD pass without triggering any warnings or notes:
lv2lint -Ewarn -Enote http://lv2plug.in/plugins/eg-scope#Stereo
If you get any warnings or notes, you can enable debugging output to help you
lv2lint -d -Ewarn -Enote http://lv2plug.in/plugins/eg-scope#Stereo
fix the problems:
By default, lv2lint runs in packager mode and skips some tests. The latter are important only for plugins that are distributed in binary form. To activate those tests, run in (nopack)ager mode:
lv2lint -Mnopack http://lv2plug.in/plugins/eg-scope#Stereo
