egui_json_tree
An interactive JSON tree visualiser for egui
, with search and highlight functionality.
Usage
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 {
bool_color: Color32::YELLOW,
..Default::default()
})
.default_expand(DefaultExpand::All)
.abbreviate_root(true) // Show {...} when the root object is collapsed.
.toggle_buttons_state(ToggleButtonsState::VisibleDisabled)
.on_render(|ui, ctx| {
// Customise rendering of the JsonTree, and/or handle interactions.
match ctx {
RenderContext::Property(ctx) => {
ctx.render_default(ui).context_menu(|ui| {
// Show a context menu when right clicking
// an array index or object key.
});
}
RenderContext::BaseValue(ctx) => {
// Show a button after non-recursive JSON values.
ctx.render_default(ui);
if ui.small_button("+").clicked() {
// ...
}
}
RenderContext::ExpandableDelimiter(ctx) => {
// Render array brackets and object braces as normal.
ctx.render_default(ui);
}
};
})
.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:
- Automatic expansion of arrays/objects and highlighting, based on search term matches.
- Copying JSON paths and values to the clipboard.
- A JSON editor UI.
