This is a parser and serializer for cDIF, an intuitive and versatile textual data interchange format. The package is written in TypeScript, so it includes type definitions. It is up to date with cDIF version 1.0.1.

To install:

npm install @mkacct/cdif

The following examples demonstrate the most basic usage of this library. The behavior can be customized in many ways; please see the documentation for details.

The CDIF constructor takes one argument which allows you to customize the behavior of the parser and serializer. For example, you can use the cdifVersion property to indicate by which major version of the cDIF specification they should abide. (If it is omitted, the latest version will be assumed.)

Check the documentation for all available configuration options.

const cdif = new CDIF(); // defaults to latest version
const cdif1 = new CDIF({cdifVersion: 1});

CDIF.parse() can be used to parse any cDIF text (with or without # directives).

const cdif = new CDIF();
const cdifText: string = /* input cDIF text */;
const value: unknown = cdif.parse(cdifText); // JS value

CDIF.serialize() returns a plain cDIF value (no # directives), while CDIF.serializeFile() allows you to add various file format elements to the output. (Check the documentation for all available file formatter configuration options.)

While not strictly necessary, configuration options are used in this example to enable formatted ("pretty-printed") output.

const cdif = new CDIF({serializer: {
    indent: "\t", // or any other string (ex. "    "), or omit to output as one line
    structureEntrySeparator: ";" // or ","
}});
const value: unknown = /* input JS value */;
// For general use:
const valueText: string = cdif.serialize(value); // cDIF value text
// For file output:
const fileText: string = cdif.serializeFile(value, {
    cdifVersionString: "1.0.1"
}); 
6DC2
// cDIF file text (includes initial "cDIF" directive)
