# Objective The name `TextAlignment` is really deceptive and almost every new user gets confused about the differences between aligning text with `TextAlignment`, aligning text with `Style` and aligning text with anchor (when using `Text2d`). ## Solution * Rename `TextAlignment` to `JustifyText`. The associated helper methods are also renamed. * Improve the doc comments for text explaining explicitly how the `JustifyText` component affects the arrangement of text. * Add some extra cases to the `text_debug` example that demonstate the differences between alignment using `JustifyText` and alignment using `Style`. <img width="757" alt="text_debug_2" src="https://github.com/bevyengine/bevy/assets/27962798/9d53e647-93f9-4bc7-8a20-0d9f783304d2"> --- ## Changelog * `TextAlignment` has been renamed to `JustifyText` * `TextBundle::with_text_alignment` has been renamed to `TextBundle::with_text_justify` * `Text::with_alignment` has been renamed to `Text::with_justify` * The `text_alignment` field of `TextMeasureInfo` has been renamed to `justification` ## Migration Guide * `TextAlignment` has been renamed to `JustifyText` * `TextBundle::with_text_alignment` has been renamed to `TextBundle::with_text_justify` * `Text::with_alignment` has been renamed to `Text::with_justify` * The `text_alignment` field of `TextMeasureInfo` has been renamed to `justification`

//! Simple text rendering benchmark.
|
|
//!
|
|
//! Creates a `Text` with a single `TextSection` containing `100_000` glyphs,
|
|
//! and renders it with the UI in a white color and with Text2d in a red color.
|
|
//!
|
|
//! To recompute all text each frame run
|
|
//! `cargo run --example many_glyphs --release recompute-text`
