Convert Case

A command line utility to convert to and from various cases.

Usage

Once installed, you can start converting strings to any case.

$ ccase -t title super_mario_64
Super Mario 64

$ ccase -f snake -t title 2020-04-15_my_cat_cali
2020-04-16 My Cat Cali

$ ccase -t camel "convert to camel"
convertToCamel

By default convert_case will determine word boundaries based on all hyphens, spaces, underscores, and changes in capitalization. You can also supply a parsing method by supplying a case with the --from -f option for more accuracy.

$ ccase -t upper "grimaldi-2003_discrete_pdf"
GRIMALDI 2003 DISCRETE PDF

$ ccase -f kebab -t upper "grimaldi-2003_discrete_pdf"
GRIMALDI 2003_DISCRETE_PDF

Convert case can handle acroynms.

$ ccase -t snake IOStream
io_stream

It also ignores leading, tailing, and duplicated delimeters.

my-bad-variable

Any special characters are also ignored.
