Colorize

The mruby-yyjson library now supports colorized JSON output, making it easier to read and debug complex JSON structures. By setting the colorize option to true in the JSON.color_generate or JSON.generate methods, you can achieve syntax-highlighted JSON output. This feature enhances the readability of nested JSON data by differentiating keys, strings, numbers, booleans, and other elements with distinct colors.

Default Colors

null: gray
boolean: yellow
number: default (no specific color)
Object keys: Colors vary by hierarchy level
- Level 1: blue
- Level 2: cyan
- Level 3: magenta
- Level 4: red
- Levels 5 and beyond: cycle through blue, cyan, magenta, and red again

Customizing Colors

You can customize these colors using the following methods:

JSON.color_null: Sets the color for null values
JSON.color_boolean: Sets the color for boolean values
JSON.color_number: Sets the color for number values
JSON.set_color_object_key(level, color): Sets the color for object keys at a specific hierarchy level

Refer to mruby-terminal-color for details on specifying colors.
