Case Conversion

This is a port of the Sublime Text 3 plugin CaseConversion, by Davis Clark’s, to a regular python package. I couldn’t find any other python packages on PyPI at the time (Feb 2016) that could seamlessly convert from any case to any other case without having to specify from what type of case I was converting. This plugin worked really well, so I separated the (non-sublime) python parts of the plugin into this useful python package. I also added Unicode support via python’s unicodedata.

Features

• Autodetection of case (no need to specify explicitly which case you are converting from!)
• Acronym detection (no funky splitting on every capital letter of an all caps acronym like HTTPError!)
• Unicode supported (non-ASCII characters are first class citizens!)
• Dependency free!
• Supports Python 3.6+
• Over 95 percent test coverage and full type annotation.
• Every case conversion from/to you ever gonna need:
  • camelCase
  • PascalCase
  • snake_case
  • dash-case (aka kebap-case, spinal-case or slug-case)
  • CONST_CASE (aka SCREAMING_SNAKE_CASE)
  • dot.case
  • separate words
  • slash/case
  • backslash\\case
  • Ada_Case
  • Http-Header-Case

Usage

Normal use is self-explanatory.

>>> import case_conversion
>>> case_conversion.dash("FOO_BAR_STRING")
'foo-bar-string'

To use acronym detection simply pass in a list of acronyms to detect as whole words.

>>> import case_conversion
>>> case_conversion.snake("fooBarHTTPError")
'foo_bar_h_t_t_p_error'  # ewwww :(
>>> case_conversion.snake("fooBarHTTPError", acronyms=['HTTP'])
'foo_bar_http_error'  # pretty :)

Unicode is fully supported - even for acronyms.

>>> import case_conversion
>>> case_conversion.const(u"fóó-bar-string")
FÓÓ_BAR_STRING
>>> case_conversion.snake("fooBarHÓÓPError", acronyms=['HÓÓP'])
'foo_bar_hóóp_error'

Install

pip install case-conversion
