fix-regex doesn't appear to work on generic

[davidfraser]

I've been trying to use fix-regex for rules applying across an entire codebase, using the generic language type. However, the rule seems to be ignored. Here's a basic use case:

rules:
- id: test-regex-pytxt
  patterns:
  - pattern: 'print(my, name)'
  fix-regex:
    regex: '(.*)\)'
    replacement: '\1, flush=True)'
  message: Honour where honour's due
  languages: [generic]
  severity: WARNING

- id: test-regex-py
  patterns:
  - pattern-either:
    - pattern: 'print(my, name)'
  fix-regex:
    regex: '(.*)\)'
    replacement: '\1, flush=True)'
  message: Honour where honour's due
  languages: [python]
  severity: WARNING

With a Python file:

print(my, name)

and a text file:

print(my, name)

semgrep with the above config and -a fixes the Python file to print(my, name, flush=True). The text file detects the [generic] rule match, but leaves the file unchanged, and doesn't apply the fix.

Hi @davidfraser ! It's possible that that the generic language doesn't support fix-regex. I will confirm first with the team.
