Examples

This folder might use unreleased code. View the examples for the latest release instead.

Warning

There may be backwards incompatible changes in these examples, as they are designed to compile against the main branch.

There are a few workaround for this problem:

• View the examples as they were when the latest version was release by selecting the tag that matches that version. E.g. https://github.com/ratatui-org/ratatui/tree/v0.26.1/examples.
• If you're viewing this file on GitHub, there is a combo box at the top of this page which allows you to select any previous tagged version.
• To view the code locally, checkout the tag. E.g. git switch --detach v0.26.1.
• Use the latest alpha version of Ratatui in your app. These are released weekly on Saturdays.
• Compile your code against the main branch either locally by adding e.g. path = "../ratatui" to the dependency, or remotely by adding git = "https://github.com/ratatui-org/ratatui"

For a list of unreleased breaking changes, see BREAKING-CHANGES.md.

We don't keep the CHANGELOG updated with unreleased changes, check the git commit history or run git-cliff -u against a cloned version of this repository.

How to update these examples

These gifs were created using VHS. Each example has a corresponding .tape file that holds instructions for how to generate the images. Note that the images themselves are stored in a separate images git branch to avoid bloating the main repository.
