ChCase is a small library to convert case of a given string between camelCase, PascalCase, snake_case, kebab-case, Sentence case, and space-separated.

This is my first attempt to create a library (yet small and straightforward though).

If you want to use this library in a flatpaked app, simply call it as a module:

modules:
  - name: chcase
    buildsystem: meson
    sources:
      - type: git
        url: https://github.com/ryonakano/chcase.git
        tag: '2.1.0'

Then call chcase in your meson file:

executable(
    meson.project_name(),
    'src/Application.vala',
    dependencies: [
        dependency('gtk+-3.0'),
        dependency('chcase')
    ],
    install: true
)

Now you can use the library in your project.

This library is not (yet) provided as a package for any distributions, so the best way to use it to your project is to embed it as a git submodule:

git submodule add https://github.com/ryonakano/chcase subprojects/chcase

Load the embeded chcase library as a dependency in the root meson.build:

chcase_subproject = subproject('chcase')
chcase_deps = chcase_subproject.get_variable('libchcase')

Add the loaded chcase_deps in the dependencies list in meson.build that has executable method:

executable(
    meson.project_name(),
    'src/Application.vala',
    dependencies: [
        dependency('gtk+-3.0'),
        chcase_deps,
    ],
    install: true
)

Now you can use the library in your project.

Set the case for input string and result string and then perform conversion.

var converter = new ChCase.Converter.with_case (ChCase.Case.SPACE_SEPARATED, ChCase.Case.CAMEL);
string input_text = "say hello to ChCase";
string output_text = converter.convert_case (input_text);
stdout.printf ("Input: %s / Output: %s\n", input_text, output_text);
// Result
// Input: say hello to ChCase / Output: sayHelloToChCase

There is an example code prepared in this repository, so it may help you.

If you mean to perform code changes and create a pull request against this project, you may want to build and install the library from source code.

You'll need the following dependencies:

• libglib2.0-dev
• meson (>= 0.56.0)
• valac

Run meson setup to configure the build environment and run meson compile to build:

meson setup builddir --prefix=/usr
meson compile -C builddir

To install, use meson install:

meson install -C builddir

You can optionally build and run a demo app:

meson configure builddir -Ddemo=true
meson compile -C builddir
./builddir/examples/example
