matdbg is now linked into the Filament Engine in debug config (allowing live inspection of GLSL / SPIRV) and into the matinfo tool (to support the --web-server option). In both cases, the library spins up a small web server that listens to http://localhost:8080. You can run any Filament app and attach to it. The web client caches all material information. This allows the user to close an atttached Filament app, and the web app will continue to function properly (useful for crash diagnosis). Moreover the user can launch a second Filament app and the web client will add its materials to the existing list (useful when comparing two Filament apps). For now this only supports inspection, not editing. Some of the material info such as required attributes is not yet displayed but this will be easy to flesh out in a subsequent PR.
Matinfo
matinfo lists the content of a compiled material as output by matc. This tool is meant to be
used for debug purpose only.
Usage
$ matinfo [options] <material file>
