utils (case conversion helpers)

What it is​

Small utility module providing string case-conversion helpers for generating identifiers from arbitrary text.

Public API​

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

Configuration/Dependencies​

  • Standard library:
    • re (used to find alphanumeric chunks via regex pattern r"[A-Za-z0-9]+")

Usage​

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

text = "hello world_42!"
print(to_pascal_case(text))  # HelloWorld42
print(to_snake_case(text))   # hello_world_42
print(to_kebab_case(text))   # hello-world-42

Caveats​

  • Only ASCII letters and digits are considered ([A-Za-z0-9]+); other characters are treated as separators and removed.
  • Existing capitalization is not preserved:
    • to_pascal_case("myAPI") becomes Myapi (chunk is capitalized, not title-cased per acronym rules).
