# Chase [![Build Status](https://travis-ci.org/lloydmeta/chase-rs.svg?branch=master)](https://travis-ci.org/lloydmeta/chase-rs) [![Crates.io](https://img.shields.io/crates/v/chase.svg)](https://crates.io/crates/chase) [![Chase](https://docs.rs/chase/badge.svg)](https://docs.rs/chase)

An implementation of async and sync file-following in Rust for people who care about line numbers.

### Goals

- Provide line numbers with each line yielded

- Ability to exit the watch loop programmatically

- Deals with file rotations automatically

- Cross-platform async 

- Configurable (which line to start on, delays and retries)

- Easy to use synchronously

- Easy to use asynchronously

  - Can receive data from a standard lib a [Channel](https://doc.rust-lang.org/std/sync/mpsc/fn.channel.html)

  - Can receive data from a `Stream` from the [Futures library](https://github.com/alexcrichton/futures-rs)

  

### Usage

You can use this tool as a lib and as a binary:

#### As lib

Some features (e.g. receiving as a `Stream`, and Serde derive for lib-provided structs) are feature-gated, so

keep that in mind when adding as a dependency (refer to `Cargo.toml` for list of features)

#### As a binary

`cargo install chase --features=binary`

```shell

Chases a file through thick and thin.

USAGE:

    chase [OPTIONS] 

FLAGS:

    -h, --help       Prints help information

    -V, --version    Prints version information

OPTIONS:

    -L, --line     The line you want to start chasing your file from [default: 0]

ARGS:

        The file you want to chase

```

  

### Caveats

Windows not yet supported: need to figure out what inodes map to
