dfmt is a formatter for D source code

dfmt is beta quality. Make backups of your files or use source control when using the --inplace option.

• Clone the repository
• Run git submodule update --init --recursive in the dfmt directory
• To compile with DMD, run make in the dfmt directory. To compile with LDC, run make ldc instead. The generated binary will be placed in dfmt/bin/.

By default, dfmt reads its input from stdin and writes to stdout. If a file name is specified on the command line, input will be read from the file instead, and output will be written to stdout.

dfmt uses EditorConfig files for configuration. If you run dfmt on a source file it will look for .editorconfig files that apply to that source file. If no file is specified on the command line, dfmt will look for .editorconfig files that would apply to a D file in the current working directory. Command line options can be used instead of .editorconfig files, or to override options found in .editorconfig files.

Formatting can be temporarily disabled by placing the comments // dfmt off and // dfmt on around code that you do not want formatted.

void main(string[] args)
{
    bool optionOne, optionTwo, optionThree;

    // dfmt has no way of knowing that "getopt" is special, so it wraps the
    // argument list normally
	getopt(args, "optionOne", &optionOne, "optionTwo", &optionTwo, "optionThree", &optionThree);

	// dfmt off
    getopt(args,
        "optionOne", &optionOne,
        "optionTwo", &optionTwo,
        "optionThree", &optionThree);
    // dfmt on
}

dfmt uses EditorConfig configuration files. dfmt-specific properties are prefixed with dfmt_.
