*go-git* is a highly extensible git implementation library written in **pure Go**.
It can be used to manipulate git repositories at low level *(plumbing)* or high level *(porcelain)*, through an idiomatic Go API. It also supports several types of storage, such as in-memory filesystems, or custom implementations, thanks to the [`Storer`](https://godoc.org/github.com/go-git/go-git/v5/plumbing/storer) interface.

It's being actively developed since 2015 and is being used extensively by [Keybase](https://keybase.io/blog/encrypted-git-for-everyone), [Gitea](https://gitea.io/en-us/) or [Pulumi](https://github.com/search?q=org%3Apulumi+go-git&type=Code), and by many other libraries and tools.

After the legal issues with the [`src-d`](https://github.com/src-d) organization, the lack of update for four months and the requirement to make a hard fork, the project is **now back to normality**.
The project is currently actively maintained by individual contributors, including several of the original authors, but also backed by a new company `gitsigth` where `go-git` is a critical component used at scale.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
## Scope

# Mergo
A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
## Status
It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc](https://github.com/imdario/mergo#mergo-in-the-wild).

### Latest release
[Release v0.3.7](https://github.com/imdario/mergo/releases/tag/v0.3.7).
### Important note
Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.
If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).
### Donations
If Mergo is useful to you, consider buying me a coffee, a beer or making a monthly donation so I can keep building great free software. :heart_eyes:

## Installation
go get github.com/imdario/mergo
// use in your .go code
import (
"github.com/imdario/mergo"
)
## Usage
You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are not considered zero values](https://golang.org/ref/spec#The_zero_value) either. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
```go
if err := mergo.Merge(&dst, src); err != nil {
// ...
}
```
Also, you can merge overwriting values using the transformer `WithOverride`.
```go
if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
// ...
}
```
Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
```go
if err := mergo.Map(&dst, srcMap); err != nil {
// ...
}
```
Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
More information and examples in [godoc documentation](http://godoc.org/github.com/imdario/mergo).
### Nice example
```go
package main
import (
"fmt"
"github.com/imdario/mergo"
)
type Foo struct {
A string
B int64
}
func main() {
src := Foo{
A: "one",
B: 2,
}
dest := Foo{
A: "two",
}
mergo.Merge(&dest, src)
fmt.Println(dest)
// Will print
// {two 2}
}
```
Note: if test are failing due missing package, please execute:
go get gopkg.in/yaml.v2
### Transformers
Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
```go
package main
import (
"fmt"
"github.com/imdario/mergo"
"reflect"
"time"
)
type timeTransfomer struct {
}
func (t timeTransfomer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
if typ == reflect.TypeOf(time.Time{}) {
return func(dst, src reflect.Value) error {
if dst.CanSet() {
isZero := dst.MethodByName("IsZero")
result := isZero.Call([]reflect.Value{})
if result[0].Bool() {
dst.Set(src)
}
}
return nil
}
}
return nil
}
type Snapshot struct {
Time time.Time
// ...
}
func main() {
src := Snapshot{time.Now()}
dest := Snapshot{}
mergo.Merge(&dest, src, mergo.WithTransformers(timeTransfomer{}))
fmt.Println(dest)
// Will print
// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
}
```

Package mergo merges same-type structs and maps by setting default values in zero-value fields.
Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
Usage
From my own work-in-progress project:
type networkConfig struct {
Protocol string
Address string
ServerType string `json: "server_type"`
Port uint16
}
type FssnConfig struct {
Network networkConfig
}
var fssnDefault = FssnConfig {
networkConfig {
"tcp",
"127.0.0.1",
"http",
31560,
},
}
// Inside a function [...]
if err := mergo.Merge(&config, fssnDefault); err != nil {
log.Fatal(err)
}
// More code [...]
*/
