utils (case conversion helpers)

What it is​

Small set of string helpers for converting arbitrary text into common identifier formats using regex tokenization.

Public API​

  • to_pascal_case(text)
    • Converts text into PascalCase by extracting alphanumeric tokens and capitalizing each.
  • to_snake_case(text)
    • Converts text into snake_case by extracting alphanumeric tokens, lowercasing them, and joining with _.
  • to_kebab_case(text)
    • Converts text into kebab-case by extracting alphanumeric tokens, lowercasing them, and joining with -.

Configuration/Dependencies​

  • Standard library only:
    • re for token extraction via re.findall(r"[A-Za-z0-9]+", text).

Usage​

from naas_abi_cli.cli.new.utils import to_pascal_case, to_snake_case, to_kebab_case

s = "Hello, world! v2"
print(to_pascal_case(s))  # HelloWorldV2
print(to_snake_case(s))   # hello_world_v2
print(to_kebab_case(s))   # hello-world-v2

Caveats​

  • Only ASCII letters and digits are considered tokens ([A-Za-z0-9]+).
    • Other characters (spaces, punctuation, underscores, hyphens, non-ASCII letters) act as separators and are not preserved.
