**Requires Go 1.13+**
|
|
|
|
This library is switched to [Go modules](https://golang.org/ref/mod) ([tl;dr](https://blog.golang.org/using-go-modules)) as of [v14.0.0](https://github.com/mxmCherry/openrtb/releases/tag/v14.0.0), so it requires Go [1.11](https://golang.org/doc/go1.11)+ (older Go versions are not capable of using versioned paths).
|
|
|
|
Also, [test/matcher library](https://github.com/onsi/gomega) relies on newer Go [error handling approach](https://blog.golang.org/go1.13-errors), so tests require Go [1.13](https://golang.org/doc/go1.13)+.

# Using
|
|
|
|
```bash
|
|
go get -u "github.com/mxmCherry/openrtb/v15/..."
|
|
```
|
|
|
|
```go
|
|
import (
|
|
openrtb2 "github.com/mxmCherry/openrtb/v15/openrtb2"
|
|
|
|
openrtb3 "github.com/mxmCherry/openrtb/v15/openrtb3"
|
|
adcom1 "github.com/mxmCherry/openrtb/v15/adcom1"
|
|
|
|
native1 "github.com/mxmCherry/openrtb/v15/native1"
|
|
nreq "github.com/mxmCherry/openrtb/v15/native1/request"
|
|
nres "github.com/mxmCherry/openrtb/v15/native1/response"
|
|
)

Master always contains latest code, so better use some package manager to vendor specific version.

# Guidelines
|
|
|
|
## Naming convention
|
|
- [UpperCamelCase](http://en.wikipedia.org/wiki/CamelCase)
|
|
- Capitalized abbreviations (e.g., `AT`, `COPPA`, `PMP` etc.)
|
|
- Capitalized `ID` keys
|
|
|
|
## Types
|
|
- Key types should be chosen according to OpenRTB specification (attribute types)
|
|
- Numeric types:
|
|
- `int8` - short enums (with values <= 127), boolean-like attributes (like `BidRequest.test`)
|
|
- `int64` - other integral types
|
|
- `float64` - coordinates, prices etc.
|
|
- Enums:
|
|
- all enums, described in section 5, must be typed with section name singularized (e.g., "5.2 Banner Ad Types" -> `type BannerAdType int8`)
|
|
- all typed enums must have constants for each element, prefixed with type name (e.g., "5.2 Banner Ad Types - XHTML Text Ad (usually mobile)" -> `const BannerAdTypeXHTMLTextAd BannerAdType = 1`)
|
|
- never use `iota` for enum constants
|
|
- OpenRTB (2.x) section "5.1 Content Categories" should remain untyped and have no constants
|
|
|
|
## Pointers/omitempty
|
|
Pointer | Omitempty | When to use | Example
|
|
------- | --------- | -------------------------------------------------------------------- | ---------------------------------
|
|
no | no | _required_ in spec | `Audio.mimes`
|
|
yes | yes | _required_ in spec, but is a part of mutually-exclusive group | `Imp.{banner,video,audio,native}`
|
|
no | yes | zero value (`""`, `0`) is useless / has no meaning | `Device.ua`
|
|
yes | yes | zero value (`""`, `0`) or value absence (`null`) has special meaning | `Device.{dnt,lmt}`
|
|
|
|
Using both pointer and `omitempty` is mostly just to save traffic / generate more "canonical" (strict) JSON.

## Documentation ([pkg.go.dev](https://pkg.go.dev/github.com/mxmCherry/openrtb/v15))
|
|
- [Godoc: documenting Go code](http://blog.golang.org/godoc-documenting-go-code)
|
|
- Each entity (type, struct key or constant) should be documented
|
|
- Comments for entities should be copy-pasted "as-is" from OpenRTB specification (except section 5 - replace "table" with "list" there; ideally, each sentence must be on a new line)
|
|
|
|
## Code organization
|
|
- Each RTB type should be kept in its own file, named after type
|
|
- File names are in underscore_case, e.g., `type BidRequest` should be declared in `bid_request.go`
|
|
- [go fmt your code](https://blog.golang.org/go-fmt-your-code)
|
|
- [EditorConfig](https://editorconfig.org/) (not required, but useful)
