Ijsonlint Processor

Purpose

Checks that JSON files parse. Native (in-process, using serde_json; no external tools required). A Rust alternative to jsonlint.

How It Works

Each file is read and parsed as JSON. A file that does not parse fails its product with the parser’s message and position:

data/bad.json: [processor.checker.ijsonlint] Invalid JSON:
data/bad.json: trailing comma at line 1 column 9

This is a well-formedness check only. There are no style rules, and duplicate keys are accepted (the last value wins).

Source Files

Input: .json files under src_dirs
Output: none (checker)

The default src_dirs is empty, so a stanza with no src_dirs or src_files checks nothing: name the directories ([""] for the whole project) or files to check.

Configuration

[processor.checker.ijsonlint]
src_dirs = [""]

Key	Type	Default	Description
`src_dirs`	string[]	`[]`	Directories to scan
`src_extensions`	string[]	`[".json"]`	File extensions to check
`dep_inputs`	string[]	`[]`	Extra files whose changes trigger rebuilds

Batch support

Files are checked individually within a batch, so one bad file fails only its own product.

Clean behavior

This processor is a Checker — rsconstruct clean outputs is a no-op for it (checkers produce no outputs). See Clean behavior and rsconstruct clean.
