serde_json_lenient   Build Status Latest Version Rustc Version 1.36+

This is a lenient JSON parser forked from the serde_json crate that is that is designed to parse JSON written by humans (e.g., JSON config files). This means that it supports:

  • /* and // style comments.
  • Trailing commas for object and array literals.
  • \v and \xDD literal escapes (for vertical tab and two-digit hexadecimal characters)
  • [planned] Unquoted object keys (precise spec TBD).

Each such feature is switchable.

Earlier work to make serde_json more lenient was performed by Michael Bolin as the crate serde_jsonrc. This crate builds on his work and updates to more recent [serde_json].

Why not make serde_json more lenient?

The maintainer wanted to keep the scope of serde_json limited to strict JSON, so we respectfully agreed that forking was the way to go.
