v0.1.4

• New: Support and documentation for sending tracing updates through a Nutmeg view.

• New: View::new is now const, so that a static view can be constructed in a global variable: you no longer need to wrap them in an Arc. See examples/static_view.

v0.1.2

Released 2022-07-27

• API change: Removed View::new_stderr and View::write_to. Instead, the view can be drawn on stderr or output can be captured using [Options::destination].
  This is better aligned with the idea that programs might have a central function that constructs a [Options], as they will probably want to consistently write to either stdout or stderr.

• New: Output can be captured for inspection in tests using [Options::destination], [Destination::Capture], and [View::captured_output].

• Improved: Nutmeg avoids redrawing if the model renders identical output to what is already displayed, to avoid flicker.

Nutmeg 0.1.1

• API change: View::message takes the message as an AsRef<str>, meaning it may be either a &str or String. This makes the common case where the message is the result of format! a little easier.

Nutmeg 0.1.0

• API change: The Write type representing the destination is no longer part of the visible public signature of View, to hide complexity and since it is not helpful to most callers.

• API change: Renamed View::to_stderr to View::new_stderr.

• New: percent_done and estimate_remaining functions to help in rendering progress bars.

• New: The models mod provides some generally-useful basic models, specifically models::StringPair, models::UnboundedModel and models::LinearModel. These build only on the public interface of Nutmeg, so also constitute examples of what can be done in application-defined models.

• New: View::finish removes the progress bar (if painted) and returns the Model. View::abandon now also returns the model.

• New: Model::final_message to let the model render a message to be printed when work is complete.

• New: The callback to View::update may return a value, and this is passed back to the caller of View::update.

• New: models::BasicModel allows simple cases to supply both an initial value and a render function inline in the View constructor call, avoiding any need to define a Model struct.

• New: View::inspect_model gives its callback a &mut to the model.

• New: Progress bars constructed by View::new and View::new_stderr are disabled when $TERM=dumb.

Nutmeg 0.0.2

• API change: Renamed nutmeg::ViewOptions to just nutmeg::Options.

• Fixed: A bug that caused leftover text when multi-line bars shrink in width.

• Fixed: The output from bars created with View::new and View::to_stderr in Rust tests is captured with the test output rather than leaking through to cargo's output.

• New method View::message to print a message to the terminal, as an alternative to using write!().

• New example/multithreaded.rs showing how a View and Model can be shared across threads.

Nutmeg 0.0.1

• Rate-limit updates to the terminal, controlled by ViewOptions::update_interval and ViewOptions::print_holdoff.

• Fix a bug where the bar was sometimes not correctly erased by View::suspend.

• Change to parking_lot mutexes in the implementation.

Nutmeg 0.0.0

Initial release. Features include:

• The application has complete control of styling, including coloring etc.
• Draw and erase progress bars.
• Write messages "under" the progress bar with writeln!(view, ...). The bar is automatically suspended and restored. If the message has no final newline, the bar remains suspended until the line is completed.
