# Contributing to mergo
First off, thanks for taking the time to contribute! ❤️
All types of contributions are encouraged and valued. See the [Table of Contents](#table-of-contents) for different ways to help and details about how this project handles them. Please make sure to read the relevant section before making your contribution. It will make it a lot easier for us maintainers and smooth out the experience for all involved. The community looks forward to your contributions. 🎉
> And if you like the project, but just don't have time to contribute, that's fine. There are other easy ways to support the project and show your appreciation, which we would also be very happy about:
> - Star the project
> - Tweet about it
> - Refer this project in your project's readme
> - Mention the project at local meetups and tell your friends/colleagues

## Table of Contents
- [Code of Conduct](#code-of-conduct)
- [I Have a Question](#i-have-a-question)
- [I Want To Contribute](#i-want-to-contribute)
- [Reporting Bugs](#reporting-bugs)
- [Suggesting Enhancements](#suggesting-enhancements)
## Code of Conduct
This project and everyone participating in it is governed by the
[mergo Code of Conduct](https://github.com/imdario/mergoblob/master/CODE_OF_CONDUCT.md).
By participating, you are expected to uphold this code. Please report unacceptable behavior
to <>.
## I Have a Question
> If you want to ask a question, we assume that you have read the available [Documentation](https://pkg.go.dev/github.com/imdario/mergo).
Before you ask a question, it is best to search for existing [Issues](https://github.com/imdario/mergo/issues) that might help you. In case you have found a suitable issue and still need clarification, you can write your question in this issue. It is also advisable to search the internet for answers first.
If you then still feel the need to ask a question and need clarification, we recommend the following:
- Open an [Issue](https://github.com/imdario/mergo/issues/new).
- Provide as much context as you can about what you're running into.
- Provide project and platform versions (nodejs, npm, etc), depending on what seems relevant.
We will then take care of the issue as soon as possible.
## I Want To Contribute
> ### Legal Notice <!-- omit in toc -->
> When contributing to this project, you must agree that you have authored 100% of the content, that you have the necessary rights to the content and that the content you contribute may be provided under the project license.
### Reporting Bugs
<!-- omit in toc -->
#### Before Submitting a Bug Report
A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to investigate carefully, collect information and describe the issue in detail in your report. Please complete the following steps in advance to help us fix any potential bug as fast as possible.
- Make sure that you are using the latest version.
- Determine if your bug is really a bug and not an error on your side e.g. using incompatible environment components/versions (Make sure that you have read the [documentation](). If you are looking for support, you might want to check [this section](#i-have-a-question)).
- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/imdario/mergoissues?q=label%3Abug).
- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue.
- Collect information about the bug:
- Stack trace (Traceback)
- OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
- Version of the interpreter, compiler, SDK, runtime environment, package manager, depending on what seems relevant.
- Possibly your input and the output
- Can you reliably reproduce the issue? And can you also reproduce it with older versions?
<!-- omit in toc -->
#### How Do I Submit a Good Bug Report?
> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. Instead sensitive bugs must be sent by email to .
<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->
We use GitHub issues to track bugs and errors. If you run into an issue with the project:
- Open an [Issue](https://github.com/imdario/mergo/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
- Explain the behavior you would expect and the actual behavior.
- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
- Provide the information you collected in the previous section.
Once it's filed:
- The project team will label the issue accordingly.
- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be implemented by someone.
### Suggesting Enhancements
This section guides you through submitting an enhancement suggestion for mergo, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
<!-- omit in toc -->
#### Before Submitting an Enhancement
- Make sure that you are using the latest version.
- Read the [documentation]() carefully and find out if the functionality is already covered, maybe by an individual configuration.
- Perform a [search](https://github.com/imdario/mergo/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
<!-- omit in toc -->
#### How Do I Submit a Good Enhancement Suggestion?
Enhancement suggestions are tracked as [GitHub issues](https://github.com/imdario/mergo/issues).
- Use a **clear and descriptive title** for the issue to identify the suggestion.
- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux. <!-- this should only be included if the project has a GUI -->
- **Explain why this enhancement would be useful** to most mergo users. You may also want to point out the other projects that solved it better and which could serve as inspiration.
<!-- omit in toc -->

## 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).
Mergo is stable and frozen, ready for production. Check a short list of the projects using at large scale it [here](https://github.com/imdario/mergo#mergo-in-the-wild).
### Important note
No new features are accepted. They will be considered for a future v2 that improves the implementation and fixes bugs for corner cases.
Please keep in mind that a problematic PR broke [0.3.9](//github.com/imdario/mergo/releases/tag/0.3.9). I reverted it in [0.3.10](//github.com/imdario/mergo/releases/tag/0.3.10), and I consider it stable but not bug-free. Also, this version adds suppot for go modules.
### Important notes
#### 1.0.0
In [1.0.0](//github.com/imdario/mergo/releases/tag/1.0.0) Mergo moves to a vanity URL `dario.cat/mergo`. No more v1 versions will be released.
If the vanity URL is causing issues in your project due to a dependency pulling Mergo - it isn't a direct dependency in your project - it is recommended to use [replace](https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive) to pin the version to the last one with the old import URL:
```
replace github.com/imdario/mergo => github.com/imdario/mergo v0.3.16
```
#### 0.3.9
Please keep in mind that a problematic PR broke [0.3.9](//github.com/imdario/mergo/releases/tag/0.3.9). I reverted it in [0.3.10](//github.com/imdario/mergo/releases/tag/0.3.10), and I consider it stable but not bug-free. Also, this version adds support for go modules.
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). I added an optional/variadic argument so that it won't break the 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 in existing projects after the change (release 0.2.0).

```
If you need to override pointers, so the source pointer's value is assigned to the destination's pointer, you must use `WithoutDereference`:
```go
package main
import (
"fmt"
"dario.cat/mergo"
)
type Foo struct {
A *string
B int64
}
func main() {
first := "first"
second := "second"
src := Foo{
A: &first,
B: 2,
}
dest := Foo{
A: &second,
B: 1,
}
mergo.Merge(&dest, src, mergo.WithOverride, mergo.WithoutDereference)
}
```
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.

@ -8,30 +8,36 @@ A helper to merge structs and maps in Golang. Useful for configuration default v
Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
Status
# Status
It is ready for production use. It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc.
Important note
# Important notes
1.0.0
In 1.0.0 Mergo moves to a vanity URL `dario.cat/mergo`.
0.3.9
Please keep in mind that a problematic PR broke 0.3.9. We reverted it in 0.3.10. We consider 0.3.10 as stable but not bug-free. . Also, this version adds suppot for go modules.
Keep in mind that in 0.3.2, Mergo changed Merge() and Map() signatures to support transformers. We added an optional/variadic argument so that it won't break the 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 in existing projects after the change (release 0.2.0).

Install
# Install
Do your usual installation procedure:
go get github.com/imdario/mergo
go get dario.cat/mergo
// use in your .go code
import (
"github.com/imdario/mergo"
)
// use in your .go code
import (
"dario.cat/mergo"
)
Usage
# 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 zero values too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).

# 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-winio [![Build Status](https://github.com/microsoft/go-winio/actions/workflows/ci.yml/badge.svg)](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
This repository contains utilities for efficiently performing Win32 IO operations in
Go. Currently, this is focused on accessing named pipes and other file handles, and
for using named pipes as a net transport.
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
newer operating systems. This is similar to the implementation of network sockets in Go's net
package.
Please see the LICENSE file for licensing information.
## Contributing
This project welcomes contributions and suggestions.
Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
you have the right to, and actually do, grant us the rights to use your contribution.
For details, visit [Microsoft CLA](https://cla.microsoft.com).
When you submit a pull request, a CLA-bot will automatically determine whether you need to
provide a CLA and decorate the PR appropriately (e.g., label, comment).
Simply follow the instructions provided by the bot.
You will only need to do this once across all repos using our CLA.
Additionally, the pull request pipeline requires the following steps to be performed before
mergining.
### Code Sign-Off
We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
to certify they either authored the work themselves or otherwise have permission to use it in this project.
A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
Please see [the developer certificate](https://developercertificate.org) for more info,
as well as to make sure that you can attest to the rules listed.
Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
### Linting
Code must pass a linting stage, which uses [`golangci-lint`][lint].
The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
automatically with VSCode by adding the following to your workspace or folder settings:
```json
"go.lintTool": "golangci-lint",
"go.lintOnSave": "package",
```
Additional editor [integrations options are also available][lint-ide].
Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
```shell
# use . or specify a path to only lint a package
# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
> golangci-lint run ./...
```
### Go Generate
The pipeline checks that auto-generated code, via `go generate`, are up to date.
This can be done for the entire repo:
```shell
> go generate ./...
```

// This limits support to Windows Vista and newer operating systems.
