CESON: Commented ECMAScript Object Notation

Yet another JSON derivative, aimed to be easy to use for humans as well as for low-level tools.

✨ 📖 ✨ spec ✨ 📖 ✨ example ✨ 📖 ✨

Main features:

• True subset of ECMAScript.
• Parser-friendly (block and line) comments.
• Comma after last value in data containers. (optional)
• Guaranteed support for UTF-8 BOM.

Related projects:

• JSONv5: A lot more flexible, and thus a lot harder to safely handle with low-level tools like sed.
• strip-json-comments

API

For examples, see test/felidae.js.

.stringify(data)

Return a CESON representation of data as a string.

.parse(ceson[, opts])

Return the data represented by the string ceson if it can be parsed, or undefined in case of a SyntaxError. Other errors are re-thrown.

You can modify the behavior by providing a config object opts. The supported keys are:

• synErr, othErr: Modify error handling. Documented at module json-parse-pmb since that's used under the hood.

.parseFile(filename, callback)

Try to parse CESON text file filename, then report to callback.
