Another example of README-driven development, this time solving a problem that might be unique to me.

I often find myself running a bunch of different Datasette instances with different databases and different in-development plugins, spreads across dozens of different terminal windows - enough that I frequently lose them!

Now I can run this:

datasette install datasette-ports
datasette ports

And get a list of every running instance that looks something like this:

http://127.0.0.1:8333/ - v1.0a26
  Databases: data
  Plugins: datasette-enrichments, datasette-enrichments-llm, datasette-llm, datasette-secrets
http://127.0.0.1:8001/ - v1.0a26
  Databases: creatures
  Plugins: datasette-extract, datasette-llm, datasette-secrets
http://127.0.0.1:8900/ - v0.65.2
  Databases: logs

Super-niche tool this. I sometimes copy prompts out of the Claude Code terminal app and they come out with a bunch of weird additional whitespace. This tool cleans that up.

• New -r/--redact option which shows the list of matches, asks for confirmation and then replaces every match with REDACTED, taking escaping rules into account.
• New Python function redact_file(file_path: str | Path, secrets: list[str], replacement: str = "REDACTED") -> int.

• No longer requires Datasette - running uvx datasette-ports now works as well.
• Installing it as a Datasette plugin continues to provide the datasette ports command.
