json-highlight-writer

A writer for json-rust object which supports highlighting slices when printing JSON objects

Usage

There are two public functions:

highlight

highlight takes a JSON object and a vector of slices you wish to highlight.

```rust use colored::; use json::; use jsonhighlightwriter::{highlightwithcolors, highlight};

let res = object!{ "code" => 200, "success" => true, "payload" => object!{ "features" => array![ "awesome", "easyAPI", "lowLearningCurve" ] } };

println!("{:#}", highlight(&res, vec![&res["code"], &res["payload"]["features"]])); ```

This code will print out the entire JSON structure with the code field and array of features highlighted in red.

highlightwithcolors

highlightwithcolors takes a JSON object, a vector of slices you wish to highlight and a vector of colors to cycle through when matching slices.

```rust println!("{:#}", highlightwithcolors(&res, vec![&res["code"], &res["payload"]["features"]], vec![Color::Red, Color::Green]));

println!("{:#}", highlightwithcolors(&res, vec![&res["payload"], &res["payload"]["features"]], vec![Color::Red, Color::Green])); ```

This code will print out the entire JSON structure twice, with the slices highlighted in red, the green. Note the inner color highlighting which is used to display matching slices in different colors if a matched slice resides inside of another matched slice.

If there are more slices than there are specified colors the highlighting will cycle back through the vector.

rust println!("{:#}", highlight_with_colors(&res, vec![&res["code"], &res["payload"], &res["payload"]["features"]], vec![Color::Red, Color::Green]));
