# Unindent
This crate provides [`indoc`]'s indentation logic for use with strings that are
not statically known at compile time. For unindenting string literals, use
`indoc` instead.
[`indoc`]: https://github.com/dtolnay/indoc
This crate exposes two functions:
- `unindent(&str) -> String`
- `unindent_bytes(&[u8]) -> Vec<u8>`
```rust
extern crate unindent;
use unindent::unindent;
fn main() {
let indented = "
line one
line two";
assert_eq!("line one\nline two", unindent(indented));
}
```
## Explanation
The following rules characterize the behavior of unindent:
1. Count the leading spaces of each line, ignoring the first line and any lines
that are empty or contain spaces only.
2. Take the minimum.
3. If the first line is empty i.e. the string begins with a newline, remove the
first line.
4. Remove the computed number of spaces from the beginning of each line.
This means there are a few equivalent ways to format the same string, so choose
one you like. All of the following result in the string `"line one\nline
two\n"`:
```
unindent(" / unindent( / unindent("line one
line one / "line one / line two
line two / line two / ")
") / ") /
```
