# go-homedir
This is a Go library for detecting the user's home directory without
the use of cgo, so the library can be used in cross-compilation environments.
Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
for a user, and `homedir.Expand()` to expand the `~` in a path to the home
directory.
**Why not just use `os/user`?** The built-in `os/user` package requires
cgo on Darwin systems. This means that any Go code that uses that package
cannot cross compile. But 99% of the time the use for `os/user` is just to
retrieve the home directory, which we can do for the current user without
cgo. This library does that, enabling cross-compilation.

# hashstructure [![GoDoc](https://godoc.org/github.com/mitchellh/hashstructure?status.svg)](https://godoc.org/github.com/mitchellh/hashstructure)
hashstructure is a Go library for creating a unique hash value
for arbitrary values in Go.
This can be used to key values in a hash (for use in a map, set, etc.)
that are complex. The most common use case is comparing two values without
sending data across the network, caching values locally (de-dup), and so on.
## Features
* Hash any arbitrary Go value, including complex types.
* Tag a struct field to ignore it and not affect the hash value.
* Tag a slice type struct field to treat it as a set where ordering
doesn't affect the hash code but the field itself is still taken into
account to create the hash value.
* Optionally, specify a custom hash function to optimize for speed, collision
avoidance for your data set, etc.
* Optionally, hash the output of `.String()` on structs that implement fmt.Stringer,
allowing effective hashing of time.Time
* Optionally, override the hashing process by implementing `Hashable`.
## Installation
Standard `go get`:
```
$ go get github.com/mitchellh/hashstructure
```
## Usage & Example
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/hashstructure).
A quick code example is shown below:
```go
type ComplexStruct struct {
Name string
Age uint
Metadata map[string]interface{}
}
v := ComplexStruct{
Name: "mitchellh",
Age: 64,
Metadata: map[string]interface{}{
"car": true,
"location": "California",
"siblings": []string{"Bob", "John"},
},
}
hash, err := hashstructure.Hash(v, nil)
if err != nil {
panic(err)
}
fmt.Printf("%d", hash)
// Output:
// 2307517237273902113
```

//
// Notes on the value:
//
// * Unexported fields on structs are ignored and do not affect the
// hash value.
//
// * Adding an exported field to a struct with the zero value will change

//
// For structs, the hashing can be controlled using tags. For example:
//
// struct {
// Name string
// UUID string `hash:"ignore"`
// }
//
// The available tag values are:
//
// * "ignore" or "-" - The field will be ignored and not affect the hash code.
//
// * "set" - The field will be treated as a set, where ordering doesn't
// affect the hash code. This only works for slices.
//
// * "string" - The field will be hashed as a string, only works when the
// field implements fmt.Stringer
