# grabinput
Unixy lib for reading from a file or from stdin
[](https://travis-ci.org/archer884/grabinput)
> Note: This library provides no real safety features. If you don't want simple, no-hassle input, don't use it. This is intended to blow up in your face if anything goes wrong. That's a feature, not a bug. Seriously, it doesn't even lock standard input before reading it. Ok? Ok. Just wanted to be sure we were clear on that. :)
## Installation
Add `grabinput = "*"` to your cargo dependencies.
## Usage
This library really is intended to be dirt simple. It doesn't do much--just allows you to skip some typing when you want to read something. Like, say you want to write a program to add up all the integers in a file...
```rust
let n: i32 = grabinput::from_args().with_fallback()
.filter_map(|n| n.trim().parse::().ok())
.sum();
```
That's your whole program now. I thought about having the library trim newlines from the end of each line, because .NET's similar library functions will do that, but I guess I just figured it was faster to let the user decide--no reason to make them pay for the work if they don't care if it's done or not, right? Anyway...
