//! indicatif is a library for Rust that helps you build command line //! interfaces that report progress to users. It comes with various //! tools and utilities for formatting anything that indicates progress. //! //! Platform support: //! //! * Linux //! * macOS //! * Windows (colors require Windows 10) //! //! Best paired with other libraries in the family: //! //! * [console](https://docs.rs/console) //! * [dialoguer](https://docs.rs/dialoguer) //! //! # Crate Contents //! //! * **Progress bars** //! * [`ProgressBar`](struct.ProgressBar.html) for bars and spinners //! * [`MultiProgress`](struct.MultiProgress.html) for multiple bars //! * **Data Formatting** //! * [`HumanBytes`](struct.HumanBytes.html) for formatting bytes //! * [`DecimalBytes`](struct.DecimalBytes.html) for formatting bytes using SI prefixes //! * [`BinaryBytes`](struct.BinaryBytes.html) for formatting bytes using ISO/IEC prefixes //! * [`HumanDuration`](struct.HumanDuration.html) for formatting durations //! * [`HumanCount`](struct.HumanCount.html) for formatting large counts //! * [`HumanFloatCount`](struct.HumanFloatCount.html) for formatting large float counts //! //! # Progress Bars and Spinners //! //! indicatif comes with a `ProgressBar` type that supports both bounded //! progress bar uses as well as unbounded "spinner" type progress reports. //! Progress bars are `Sync` and `Send` objects which means that they are //! internally locked and can be passed from thread to thread. //! //! Additionally a `MultiProgress` utility is provided that can manage //! rendering multiple progress bars at once (eg: from multiple threads). //! //! To whet your appetite, this is what this can look like: //! //! //! //! Progress bars are manually advanced and by default draw to stderr. //! When you are done, the progress bar can be finished either visibly //! (eg: the progress bar stays on the screen) or cleared (the progress //! bar will be removed). //! //! ```rust //! use indicatif::ProgressBar; //! //! let bar = ProgressBar::new(1000); //! for _ in 0..1000 { //! bar.inc(1); //! // ... //! } //! bar.finish(); //! ``` //! //! General progress bar behaviors: //! //! * if a non terminal is detected the progress bar will be completely //! hidden. This makes piping programs to logfiles make sense out of //! the box. //! * a progress bar only starts drawing when `set_message`, `inc`, `set_position` //! or `tick` are called. In some situations you might have to call `tick` //! once to draw it. //! * progress bars should be explicitly finished to reset the rendering //! for others. Either by also clearing them or by replacing them with //! a new message / retaining the current message. //! * the default template renders neither message nor prefix. //! //! # Iterators //! //! Similar to [tqdm](https://github.com/tqdm/tqdm), progress bars can be //! associated with an iterator. For example: //! //! ```rust //! use indicatif::ProgressIterator; //! //! for _ in (0..1000).progress() { //! // ... //! } //! ``` //! //! See the [`ProgressIterator`](trait.ProgressIterator.html) trait for more //! methods to configure the number of elements in the iterator or change //! the progress bar style. Indicatif also has optional support for parallel //! iterators with [Rayon](https://github.com/rayon-rs/rayon). In your //! `Cargo.toml`, use the "rayon" feature: //! //! ```toml //! [dependencies] //! indicatif = {version = "*", features = ["rayon"]} //! ``` //! //! And then use it like this: //! //! ```rust,ignore //! # extern crate rayon; //! use indicatif::ParallelProgressIterator; //! use rayon::iter::{ParallelIterator, IntoParallelRefIterator}; //! //! let v: Vec<_> = (0..100000).collect(); //! let v2: Vec<_> = v.par_iter().progress_count(v.len() as u64).map(|i| i + 1).collect(); //! assert_eq!(v2[0], 1); //! ``` //! //! Or if you'd like to customize the progress bar: //! //! ```rust,ignore //! # extern crate rayon; //! use indicatif::{ProgressBar, ParallelProgressIterator, ProgressStyle}; //! use rayon::iter::{ParallelIterator, IntoParallelRefIterator}; //! //! // Alternatively, use `ProgressBar::new().with_style()` //! let style = ProgressStyle::default_bar(); //! let v: Vec<_> = (0..100000).collect(); //! let v2: Vec<_> = v.par_iter().progress_with_style(style).map(|i| i + 1).collect(); //! assert_eq!(v2[0], 1); //! ``` //! //! # Templates //! //! Progress bars can be styled with simple format strings similar to the //! ones in Rust itself. The format for a placeholder is `{key:options}` //! where the `options` part is optional. If provided the format is this: //! //! ```text //! <^> for an optional alignment specification (left, center and right respectively) //! WIDTH an optional width as positive integer //! ! an optional exclamation mark to enable truncation //! .STYLE an optional dot separated style string //! /STYLE an optional dot separated alternative style string //! ``` //! //! For the style component see [`Style::from_dotted_str`](https://docs.rs/console/0.7.5/console/struct.Style.html#method.from_dotted_str) //! for more information. Indicatif uses the `console` base crate for all //! colorization and formatting options. //! //! Some examples for templates: //! //! ```text //! [{elapsed_precise}] {bar:40.cyan/blue} {pos:>7}/{len:7} {msg} //! ``` //! //! This sets a progress bar that is 40 characters wide and has cyan //! as primary style color and blue as alternative style color. //! Alternative styles are currently only used for progress bars. //! //! Example configuration: //! //! ```rust //! # use indicatif::{ProgressBar, ProgressStyle}; //! # let bar = ProgressBar::new(0); //! bar.set_style(ProgressStyle::with_template("[{elapsed_precise}] {bar:40.cyan/blue} {pos:>7}/{len:7} {msg}") //! .unwrap() //! .progress_chars("##-")); //! ``` //! //! The following keys exist: //! //! * `bar`: renders a progress bar. By default 20 characters wide. The //! style string is used to color the elapsed part, the alternative //! style is used for the bar that is yet to render. //! * `wide_bar`: like `bar` but always fills the remaining space. It should not be used with //! `wide_msg`. //! * `spinner`: renders the spinner (current tick string). //! * `prefix`: renders the prefix set on the progress bar. //! * `msg`: renders the currently set message on the progress bar. //! * `wide_msg`: like `msg` but always fills the remaining space and truncates. It should not be used //! with `wide_bar`. //! * `pos`: renders the current position of the bar as integer //! * `human_pos`: renders the current position of the bar as an integer, with commas as the //! thousands separator. //! * `len`: renders the amount of work to be done as an integer //! * `human_len`: renders the total length of the bar as an integer, with commas as the thousands //! separator. //! * `bytes`: renders the current position of the bar as bytes. //! * `percent`: renders the current position of the bar as a percentage of the total length. //! * `total_bytes`: renders the total length of the bar as bytes. //! * `elapsed_precise`: renders the elapsed time as `HH:MM:SS`. //! * `elapsed`: renders the elapsed time as `42s`, `1m` etc. //! * `per_sec`: renders the speed in steps per second. //! * `bytes_per_sec`: renders the speed in bytes per second. //! * `binary_bytes_per_sec`: renders the speed in bytes per second using //! power-of-two units, i.e. `MiB`, `KiB`, etc. //! * `eta_precise`: the remaining time (like `elapsed_precise`). //! * `eta`: the remaining time (like `elapsed`). //! * `duration_precise`: the extrapolated total duration (like `elapsed_precise`). //! * `duration`: the extrapolated total duration time (like `elapsed`). //! //! The design of the progress bar can be altered with the integrated //! template functionality. The template can be set by changing a //! `ProgressStyle` and attaching it to the progress bar. //! //! # Human Readable Formatting //! //! There are some formatting wrappers for showing elapsed time and //! file sizes for human users: //! //! ```rust //! # use std::time::Duration; //! use indicatif::{HumanBytes, HumanCount, HumanDuration, HumanFloatCount}; //! //! assert_eq!("3.00 MiB", HumanBytes(3*1024*1024).to_string()); //! assert_eq!("8 seconds", HumanDuration(Duration::from_secs(8)).to_string()); //! assert_eq!("33,857,009", HumanCount(33857009).to_string()); //! assert_eq!("33,857,009.1235", HumanFloatCount(33857009.123456).to_string()); //! ``` //! //! # Feature Flags //! //! * `rayon`: adds rayon support //! * `improved_unicode`: adds improved unicode support (graphemes, better width calculation) #![cfg_attr(docsrs, feature(doc_cfg))] #![warn(unreachable_pub)] mod draw_target; mod format; #[cfg(feature = "in_memory")] mod in_memory; mod iter; mod multi; mod progress_bar; #[cfg(feature = "rayon")] mod rayon; mod state; pub mod style; mod term_like; pub use crate::draw_target::ProgressDrawTarget; pub use crate::format::{ BinaryBytes, DecimalBytes, FormattedDuration, HumanBytes, HumanCount, HumanDuration, HumanFloatCount, }; #[cfg(feature = "in_memory")] pub use crate::in_memory::InMemoryTerm; pub use crate::iter::{ProgressBarIter, ProgressIterator}; pub use crate::multi::{MultiProgress, MultiProgressAlignment}; pub use crate::progress_bar::{ProgressBar, WeakProgressBar}; #[cfg(feature = "rayon")] pub use crate::rayon::ParallelProgressIterator; pub use crate::state::{ProgressFinish, ProgressState}; pub use crate::style::ProgressStyle; pub use crate::term_like::TermLike;
