ccaseA command line utility to convert to and from various cases. ccase is short for "convert case."
Once installed, you can start converting strings to any case. ``` $ ccase -t title supermario64 Super Mario 64
$ ccase -f snake -t title 2020-04-15mycat_cali 2020-04-16 My Cat Cali
$ ccase -t camel "convert to camel" convertToCamel ```
By default ccase 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-2003discretepdf"
GRIMALDI 2003 DISCRETE PDF
$ ccase -f kebab -t upper "grimaldi-2003discretepdf" GRIMALDI 2003DISCRETEPDF ```
This binary was written with a very specific use case in mind (so the author could do a cool one-liner.) Given a list of file names in snake case
$ ls ~/roms
donkey_kong_64.z64
kirby_64_the_crystal_shards.z64
super_mario_64.z64
write out a list of nicely formatted title-case game titles. After removing the file extension using cut, with ccase one can do the following.
$ ls ~/roms | cut -d '.' -f 1 | ccase -f snake -t title
Donkey Kong 64
Kirby 64 The Crystal Shards
Super Mario 64
ccase can handle acroynms.
$ ccase -t snake IOStream
io_stream
It also ignores leading, tailing, and duplicated delimeters.
$ ccase -t kebab __my bad-_variable-
my-bad-variable
Any special characters are also ignored.
$ ccase -t screamingsnake "10,000 Days"
10,000_DAYS
Unicode support!
$ ccase -t pascal "granat-äpfel"
GranatÄpfel
You need cargo to install this utility. You can get cargo from
curl https://sh.rustup.rs -sSf | sh
Once cargo is installed,
cargo install ccase
convert_caseccase was written in Rust and is ready to be used inline with your rust code as a library. You can read the convert_case documentation on docs.rs.
You can also view the list of cases using the --list -l option. Some cases are simply aliases of others.
