While trying to make slither work with pre-commit, I noticed slither expects a single file, or directory as CLI args, whereas (my) pre-commit-config.yaml provides slither with a list of space separated filenames.

Working in CLI

After installing slither with: python3 -m pip install slither-analyzer one can use it like:

slither src
slither .
slither src/some_file.sol
slither src/anotherfile.sol
slither test
slither test/some_test_file

These all allow slither to run successfully.

Pre-commit config

However, The following pre-commit config:

 - repo: local
   hooks:
     - id: slither
       name: Slither analysis for smart contracts
       entry: slither .
       language: system
      #  folder: src
      #  files: src
      #  files: ^(src/)
      #  files: ^(src/DecentralisedInvestmentManager.sol)

yields output:

...

    - file.sol // a Solidity file
    - project_directory // a project directory. See https://github.com/crytic/crytic-compile/#crytic-compile for the supported platforms

...

Because slither expects 1 file or a folder, not a list of files/folders.

Question

How can I change my pre-commit-config.yaml to call slither twice with a different folder src and test (or multiple times with one relative filepath per call {instead of a list of space separated relative filepaths})?
