Development

Setup

  1. Install poetry
  2. Install dev dependencies:
poetry install
  1. Activate the poetry shell:
poetry shell

Testing

  1. Run maturin develop to compile the Rust code.
  2. Run make fmt, make lint, and make test.

  • why is unicode segmentation used?

    why is unicode segmentation used?

    Just curious. Basically, in the context of this line:

    https://github.com/kevinheavey/pyheck/blob/28fa3d995c73e4931421a361748a588ec1774ebf/Cargo.toml#L17

    I'm not too sure about what the unicode feature is myself, reading up on it in the heck docs now.

    Currently i have some test code in rust at least:

    assert_eq!("a.b.c".to_snake_case(), "a_b_c");
assert_eq!("a'b'c".to_snake_case(), "a_b_c");
assert_eq!("2this##@$@#$.23432isaTest.Thanks.To.BOB.Myf\"r'e\"'e''nd.".to_snake_case(),
                 "2this_23432isa_test_thanks_to_bob_myf_r_e_e_nd")

    this appears to work without the unicode feature, i.e. with heck = "0.4.0", but when I add the unicode feature then the assert stmts seem to fail. I might be wrong, but for valid snake case it might be worth removing the . and the , in the results. Basically, in my use case I want to turn a bunch of words into valid identifier names in python -- so for ex. a_b_c = 2 would work out in my use case, but with special chars it would fail. Is it possible to just have a _ in the returned string?

    Side note: also 2this is not a valid identifier in python, but I understand that's not a goal of this library for obvious reasons of course.
