yes I know, I was just commenting on what the future PR should probably support in terms of UX (in response to [this](https://github.com/sphinx-contrib/emojicodes/issues/40#issuecomment-1356489717)) :)

My original intention with this feature request was just the first bit (`aws s3 cp local_path_in_repo s3://remote_path`, or even just `aws s3 cp local_path_NOT_in_repo s3://remote_path`). I don't have any strong...

We'd need specific per-language support (based on file extension) to extract source code of functions/classes and md5 hash them. Python would be a first obvious language to support but in...

Not sure whether going "all Python" would be a different implementation than supporting other langs. We'd probably still have to check file extensions/types and print out errors if it's a...

Well we could support a user-defined external filter tool (similar to `git`): ``` deps: - md5: 409a438ee6ac70fc1f911631412325ea path: utils.py filter: python extract_function.py --name foo ```

@elgehelge good point, but I think it's fine for `dvc` to give users double-edged swords with *caveat emptor* warnings. If we go down the "support user-defined `filter: `" route then...

I would recommended *against* a `type: python`. > ``` > - type: python                         #    checksum: 1df9d34e2031bb7e8 >   path: utils.py >  function: utils.check_db > ``` Should be: ``` - type: cmd   ...

So we're down to 2 options: ```yaml type: cmd # or potentially other things cmd: custom_filter ``` or ```yaml filter: custom_filter ``` I still prefer the latter (and as a...
