JSON fixer for Humans
=====================
[![npm version][]][fixjson]
[![ci-badge][]][ci]
[fixjson][] is a JSON file fixer/formatter for humans using (relaxed) JSON5.
fixjson provides:
- Pretty-printing JSON5 input
- ES5 syntax is available to write up JSON
- Fixes various failures while humans writing JSON
- Fixes trailing commas objects or arrays
- Fixes missing commas for elements of objects or arrays
- Adds quotes to keys in objects
- Newlines in strings
- Hex numbers
- Fixes single quotes to double quotes
fixjson reads an input in [relaxed JSON5][forked json5] format and outputs it in JSON format. Indent
width is automatically detected.
This CLI tool aims to be used with editor extensions.
- [vim-fixjson][] (dedicated Vim plugin)
- [ALE][] (Vim plugin)
- [neoformat][] (Vim plugin)
- [vim-autoformat][] (Vim plugin)
## Screenshots of Fixes
When moving a line to another line, you no longer need to care about a trailing comma:
And you also don't need to care about a trailing comma of a previous line when adding a new element
to an object or an array:
When adding a new key-value to an object, quotes of the key are fixed. And single quotes for strings
are also fixed to double quotes:
JSON string does not allow multi-line string. `\n` is required to embed multi-line string to JSON.
fixjson automatically fixes newlines in strings. This is useful when copy&paste some string to JSON
file:
JSON only accepts decimal digits for numbers. fixjson automatically converts `0x` hex numbers to
decimal numbers. You no longer need to convert hex numbers manually:
And of course it pretty-prints the JSON code, with automatic indent detection:
## Installation
```sh
$ npm install -g fixjson
```
It installs `fixjson` command globally.
## Usage
```sh
fixjson [--write|--indent|--minify|--stdin-filename] [paths...]
```
If paths are given, glob such as `dir/**/*.json` is available. If the path is a directory, it formats
all JSON files in the directory. If no path is given, it reads from STDIN.
If `--write` (or `-w`) option is provided, it overwrites files.
If `--indent {num}` (or `-i {num}`) is not provided, it detects indent spaces.
Please see `fixjson --help` for more details.
