# prettyprint
[](https://docs.rs/prettyprint/)
Syntax highlighting library with batteries included.
> :warning: For new projects, you might want to use [`bat`](https://github.com/sharkdp/bat/) instead,
> which can be used as a library now. `prettyprint` is in maintenance mode now, which means it will
> not see any major updates anymore, but pull requests will still be reviewed and dependencies will
> be kept up-to-date for the time being. You might want consider migrating away, though.
## Quick start
The above output was created with the following code:
```rust
let printer = PrettyPrinter::default()
.language("rust")
.build()?;
printer.file("fixtures/fib.rs")?;
```
Note that `prettyprint` is a [builder](https://github.com/rust-unofficial/patterns/blob/master/patterns/builder.md) and can be customized. For example, if you don't like the grid or the header, you can disable those:
```rust
let printer = PrettyPrinter::default()
.header(false)
.grid(false)
.language("ruby")
.build()?;
let example = r#"
def fib(n)
return 1 if n <= 1
fib(n-1) + fib(n-2)
end
"#;
printer.string_with_header(example, "fib.rb")?;
```
"What!? It can also print strings, Matthias? That's insane."
It's true. You're welcome.
## Installation
Add this to your `Cargo.toml`:
```TOML
prettyprint = "*"
```
## But why?
[`syntect`](https://github.com/trishume/syntect/) is a great package for highlighting text.
When writing a command-line tool that prints text however, you might be looking for some additional functionality.
* Line numbers
* More built-in color-themes
* Automatic pagination
* Proper terminal handling
* Showing non-printable characters
* File headers
* Windows support
`prettyprint` offers all of this in one crate (thanks to [bat](https://github.com/sharkdp/bat/)).
## Known limitations
* Doesn't run on `no-std` targets. I don't plan to support those.
## Credits
`prettyprint` is simply a fork of [`bat`](https://github.com/sharkdp/bat/), with some functionality stripped out and bundled up as a library.
I built it, because [I needed it](https://github.com/sharkdp/bat/issues/423) for [cargo-inspect](https://github.com/mre/cargo-inspect/).
All credits go to the original authors.
