eguijsontree

An interactive JSON tree visualiser for egui, with search and highlight functionality.

Usage

```rust use egui::{Color32}; use eguijsontree::{DefaultExpand, JsonTree, JsonTreeStyle};

let value = serde_json::json!({ "foo": "bar", "fizz": [1, 2, 3]});

// Simple: JsonTree::new("simple-tree", &value).show(ui);

// Customised: let response = JsonTree::new("customised-tree", &value) .style(JsonTreeStyle { boolcolor: Color32::YELLOW, ..Default::default() }) .defaultexpand(DefaultExpand::All) .responsecallback(|response, jsonpointerstring| { // Handle interactions within the JsonTree. }) .abbreviateroot(true) // Show {...} when the root object is collapsed. .show(ui);

// Reset the expanded state of all arrays/objects to respect the default_expand setting. response.reset_expanded(ui); ```

See demo.rs and run the examples for more detailed use cases, including the search match highlight/auto expand functionality, and how to copy JSON paths and values to the clipboard.

JsonTree can visualise any type that implements value::ToJsonTreeValue. An implementation to support serde_json::Value is provided with this crate. If you wish to use a different JSON type, see the value module, and disable default features in your Cargo.toml if you do not need the serde_json dependency.

Run Examples

bash cargo run --example=demo
