One of the frustrating things that can arise with VcvRack is when a patch ( or selection ) doesn’t load completely, usually because of one or more missing modules. There’s lots of options in the library, so typically if you don’t have the exact unit required, there can be ample opportunity for the substitution of something similar. And, yes I realize there are limits to that approach. The real PIA/PIB is trying to figure out what the missing module had as inputs as well as its outputs. You can, knowing the module ID, find the cables attached to it and the other modules that are connected by searching through the JSON for the patch (or selection), but it is a PIA/PIB to accomplish.
VcvDump does this for you. Its a comand line utility that displays a list of modules, cables, and the details for a given module. Native windows, native linux, and executable JAR files are here in appropo folders:
https://drive.google.com/drive/folders/10bbwmyWKxCXUnCW45NnI6Wq1GuI9x7TO?usp=sharing
IMPORTANT - you must pass a text/json file to it for it to work. This version will NOT work on “vcv” files that are compressed. Of course the current loaded patch is available in the autosave folder as “patch.json”, that will work, as well as any selection, “vcvs”, file. [ In a future version maybe get the decompression to work, if there’s enough interest]. Execute it without parameters and it displays what its expecting. Here’s some output, with example command lines:
