A bunch of helper functions for go-openapi and go-swagger projects.
You may also use it standalone for your projects.
> **NOTE**
> `swag` is one of the foundational building blocks of the go-openapi initiative.
>
> Most repositories in `github.com/go-openapi/...` depend on it in some way.
> And so does our CLI tool `github.com/go-swagger/go-swagger`,
> as well as the code generated by this tool.

## Status
API is stable.
## Import this library in your project
```cmd
go get github.com/go-openapi/swag/{module}
```
Or for backward compatibility:
```cmd
go get github.com/go-openapi/swag
```
## Contents
`go-openapi/swag` exposes a collection of relatively independent modules.
Moving forward, no additional feature will be added to the `swag` API directly at the root package level,
which remains there for backward-compatibility purposes. All exported top-level features are now deprecated.
Child modules will continue to evolve and some new ones may be added in the future.
| Module | Content | Main features |
|---------------|---------|---------------|
| `cmdutils` | utilities to work with CLIs ||
| `conv` | type conversion utilities | convert between values and pointers for any types
convert from string to builtin types (wraps `strconv`)
require `./typeutils` (test dependency)
|
| `fileutils` | file utilities | |
| `jsonname` | JSON utilities | infer JSON names from `go` properties
|
| `jsonutils` | JSON utilities | fast json concatenation
read and write JSON from and to dynamic `go` data structures
~require `github.com/mailru/easyjson`~
|
| `loading` | file loading | load from file or http
require `./yamlutils`
|
| `mangling` | safe name generation | name mangling for `go`
|
| `netutils` | networking utilities | host, port from address
|
| `stringutils` | `string` utilities | search in slice (with case-insensitive)
split/join query parameters as arrays
|
| `typeutils` | `go` types utilities | check the zero value for any type
safe check for a nil value
|
| `yamlutils` | YAML utilities | converting YAML to JSON
loading YAML into a dynamic YAML document
maintaining the original order of keys in YAML objects
require `./jsonutils`
~require `github.com/mailru/easyjson`~
require `go.yaml.in/yaml/v3`
|
---
## Dependencies
The root module `github.com/go-openapi/swag` at the repo level maintains a few
dependencies outside of the standard library.
* YAML utilities depend on `go.yaml.in/yaml/v3`
* JSON utilities depend on their registered adapter module:
* by default, only the standard library is used
* `github.com/mailru/easyjson` is now only a dependency for module
`github.com/go-openapi/swag/jsonutils/adapters/easyjson/json`,
for users willing to import that module.
* integration tests and benchmarks use all the dependencies are published as their own module
* other dependencies are test dependencies drawn from `github.com/stretchr/testify`
## Usage
**How to explicitly register a dependency at runtime**?
The following would maintain how JSON utilities proposed by `swag` used work, up to `v0.24.1`.
```go
import (
"github.com/go-openapi/swag/jsonutils/adapters"
easyjson "github.com/go-openapi/swag/jsonutils/adapters/easyjson/json"
)
func init() {
easyjson.Register(adapters.Registry)
}
```
Subsequent calls to `jsonutils.ReadJSON()` or `jsonutils.WriteJSON()` will switch to `easyjson`
whenever the passed data structures implement the `easyjson.Unmarshaler` or `easyjson.Marshaler` respectively,
or fallback to the standard library.
For more details, you may also look at our
[integration tests](jsonutils/adapters/testintegration/integration_suite_test.go#29).

## Note to contributors
All kinds of contributions are welcome.
This repo is a go mono-repo. See [docs](docs/MAINTAINERS.md).

## Roadmap
See the current [TODO list](docs/TODOS.md)
## Change log
See
For pre-v0.26.0 releases, see [release notes](./docs/NOTES.md).
**What coming next?**
Moving forward, we want to :
* provide an implementation of the JSON adapter based on `encoding/json/v2`, for `go1.25` builds.
* provide similar implementations for `goccy/go-json` and `jsoniterator/go`, and perhaps some other
similar libraries may be interesting too.
