I’m pleased to announce the 0.2.0 release of [`Progress`](https://github.com/craigfe/progress), now available via Opam.

`Progress` is an OCaml library for defining and using progress bars. It has the following features:

- allows user-defined progress bar layouts;
- supports rendering multiple progress bars simultaneously;
- dynamically responds to changes in terminal size;
- supports interleaving logging with progress bar rendering.

This second release contains a much-improved DSL for specifying progress bars, alongside improvements and extensions to the rendering logic. The bars in the screenshot above are defined as follows:

```nohighlight
let bar ~color ~total =
  let open Progress.Line in
  list
    [ spinner ~color:(Progress.Color.ansi `green) ()
    ; brackets (elapsed ())
    ; bar ~color total
    ; bytes
    ; parens (const "eta: " ++ eta total)
    ]

```

It also comes with more complete [documentation](https://craigfe.github.io/progress/progress/Progress/index.html) and many more [examples](https://github.com/CraigFe/progress/tree/main/examples), including:

- a Cargo-like progress bar w/ logging of intermediate results:

- a Yarn-like stack of spinners:

- a showcase of various progress bar styles:

The changelog is [here](https://github.com/CraigFe/progress/blob/0.2.0/CHANGES.md#020-2021-06-26) and the API documentation is [here](https://craigfe.github.io/progress/progress/Progress/index.html). The library is not yet feature-complete, but should still be reasonably useful 🙂 Happy hacking!
