Examples

• Simply update the VapourSynth stubs:

  vsstubs
  

• Generate a template stubs:

  vsstubs -o out.pyi --template
  

• Add plugin stubs:

  vsstubs -i out.pyi -o @ add resize2
  

• Remove plugin stubs (On Powershell you will need to escape the @ character):

  vsstubs -i out.pyi -o "@" remove resize2

Why use this over vsrepo genstubs?

• Much faster than genstubs.
• More accurate typing: the generated stubs better reflect the actual signatures of plugins, core classes, and functions.
• Modern Python typing.
• Easier to maintain and extend than genstubs.
• More flexible workflow: supports generating blank templates, checking for new plugin signatures, and selectively adding/removing plugins.
