A Rust utility crate for converting variable names from camelCase to snake_case.

Add the following dependency to your Cargo.toml file:

[dependencies]
untools = "1.0.0" # This is just an example. It is recommended to use the latest version number.

use untools::camel_to_snake;

fn main() {
    let camel_case_name = "myVariableName";
    let snake_case_name = camel_to_snake(camel_case_name, true);
    assert!("MY_VARIABLE_NAME', snake_case_name);
}

use untools::batch_convert;

fn main() {
    // Specify the input file, output file, naming convention, and whether to operate in silent mode.
    batch_convert("input.txt", "output.txt", true, false);
}

In the example above:

• "input.txt" is the path to the input file containing variable names to be converted.
• "output.txt" is the path to the output file where the converted variable names will be written.
• true indicates that the variable names will be converted to SCREAMING_SNAKE_CASE. Set it to false for camelCase conversion.
• false indicates that the program will not run in silent mode.

$ untools -h
Usage: untools [OPTIONS] <--camel-to-snake|--snake-to-camel|--batch <OUTPUT_FILE>> <INPUT>

Arguments:
  <INPUT>

Options:
  -c, --is-constant
      --camel-to-snake
      --snake-to-camel
      --batch <OUTPUT_FILE>
  -s, --silent
  -h, --help                 Print help
  -V, --version              Print version
$ untools --camel-to-snake "helloWorld" -c -s
HELLO_WORLD
$ untools --snake-to-camel "hello_world" -c -s
HelloWorld
$ untools --camel-to-snake "hello_world" -s
helloWorld
$ untools --batch "input.txt" "output.txt" -s 

Here are the features and improvements we plan to add to the tool in the future. If you have any suggestions or ideas, feel free to share!

1. Support for Multiple Naming Conventions:
   • Add support for other naming conventions such as SCREAMING_SNAKE_CASE.
2. Batch Conversion Feature:
   • ✅ Allow users to convert multiple variable names at once.
3. Interactive Mode:
   • ✅ Create an interactive command-line interface for a more intuitive user experience. #3
4. File Processing Feature:
   • ✅ Support batch conversion of variable names in files.
5. Custom Rules:
   • Enable users to define custom conversion rules.
6. Integration with Editor Plugins:
   • Develop editor plugins to allow users to use the conversion tool directly in their editors.
7. GUI Interface:
   • Develop a graphical user interface for a more user-friendly experience.
8. Support reverse conversion
   • ✅ Convert underscores to PascalCase .
