# hare-update

hare-update is a Hare add-on which assists in migrating a Hare codebases to a
newer release of Hare by scanning your code, identifying areas impacted by
breaking changes, and suggesting the appropriate fix.

**RFC**: This tool is a work-in-progress. Feedback (and patches) welcome.

## Installation

```
$ make
# make install
$ hare tool update -h
```

## Usage

Run `hare tool update` to apply upgrades from Hare version N-1 to version N,
where N is the latest stable release of Hare. To upgrade to a different release,
use `hare tool update -l` to list supported releases.

If building from the development branch (rather than a tagged release of
hare-update), by default hare-update will update your codebase to support the
development branch of Hare upstream (i.e. "v0.next").
