  • Documentation is clear, if a little poorly formatted.
    • Not the biggest fan of the monospace type as body copy.
    • I like the queries tab but it's not immediately obvious that it's something that I can interact with.
  • Document the data that gets returned!
  • Correct types.
    • Numbers should be unquoted
    • Are all the "note on count/percentage"s the same for every endpoint? If

Here are some things you can do with Gists in GistBox.

# It is possible for `to` to be passed in with **kwargs. Since
# ContentType is hardcoded in for the `to` arg when calling super(),

Installing PARI/GP on Mac

Prerequisites

  • Apple Developer Tools
    • Note: this is like 2GB. You might be better off simply installing the gcc compiler from here. I actually have no idea if this will work but if somebody is brave enough to try, that'd be awesome.
  • Slight knowledge of the command line (or at least a little bravery and some faith).
You can’t perform that action at this time.
