Converts to and from various cases.

Convert case was written in Rust and is ready to be used inline with your rust code as a library.

use convert_case::{Case, Casing};assert_eq!("ronnieJamesDio", "Ronnie_James_dio".to_case(Case::Camel));assert_eq!("io_stream", "IOStream".to_case(Case::Snake));assert_eq!(    "2020-04-16 My Cat Cali",    "2020-04-16_my_cat_cali".from_case(Case::Snake).to_case(Case::Title));

You can read the API documentation ondocs.rs for a list of all features and read lots of examples.

Thecommand line utilityccase was made to expose the tools of theconvert_case library to the command line.

$ ccase -t title super_mario_64Super Mario 64$ ccase -f snake -t title 2020-04-15_my_cat_cali2020-04-16 My Cat Cali$ ccase -t camel "convert to camel"convertToCamel

This is list of cases that convert_case supports. Some cases are simply aliases of others. The "Random" and "PseudoRandom" cases are provided in theconvert_case library with the "random" feature.

Pattern is no longer an enum. It is now a type alias forfn(&[&str]) -> Vec<String>. The variants of Pattern can now be referenced as functions inside thepattern module. For upgrading this means changingPattern::Lowercase topattern::lowercase, and calling the function directly instead of invoking themutate method on the enum.

Inside the pattern module is also the type aliasPattern itself.

Other breaking changes:

• AddCase::Ada (capital pattern with underscore delimiter.)
• AddCase::Custom variant. It is a struct variant that takes three parameters:
  • pattern with typePattern
  • delim with type&static str, and
  • boundaries with type&'static [Boundary].
• Because of the newpattern::noop function,Converter attributepattern is now of typePattern and notOption<Pattern>
• Case::deterministic_cases,Case::all_cases, andCase::random_cases now return static arrays instead of vecs

Other changes:

• AddedCase::split,Case::mutate, andCase::join which expose operations related to the boundaries, pattern, and delimiter of a case
• Is nowno_std compatible

• Removed debug print statement.

Boundary is no longer an enum. It now is a struct, and each enum variant cooresponds to an associated constant. For upgrading this just means changingBoundary::LowerUpper to justBoundary::LOWER_UPPER.

The benefit of this is that you can make your boundary conditions now, by instantiating theBoundary struct, or usingBoundary::from_delim(). Now you can split on newlines, periods, double-colons, emojis, or a more complex case like a symbol followed by a digit. You also define which characters, if any, are removed during segmentation, and where the split happens.

Changes from this feature:

• PreviousBoundary::PascalName enum variants now much refered to asBoundary::CONSTANT_NAME constants.
• All functions that returned groups of boundaries (such asBoundary::defaults(),Boundary::digit_letter(), etc) now are const and return fixed-sized arrays[Boundary; N], notVec<Boundary>.
• Boundary::all() was removed, since there's no longer a sense of "all" boundaries, since you can create your own.
• Boundary::list_from() has been renamed toBoundary::defaults_from() and no longer outputsBoundary::UPPER_LOWER, since this function now only checks default boundaries.
• Create custom delimiter boundaries usingBoundary::from_delim().

Other breaking changes:

• RenameCase::ScreamingSnake toCase::Constant.
• AddCase::Sentence (sentence pattern and space delimiter.)
• Casing trait implemented forArc<str> andRc<str> again.

Other changes:

• Remove most imports from doc comments.
• Remove loop overstr::chars in favor ofgraphemes fromunicode-segmentation.
