# Contributor Code of Conduct
This project adheres to [The Code Manifesto](http://codemanifesto.com)
as its guidelines for contributor interactions.
## The Code Manifesto
We want to work in an ecosystem that empowers developers to reach their
potential — one that encourages growth and effective collaboration. A space
that is safe for all.
A space such as this benefits everyone that participates in it. It encourages
new developers to enter our field. It is through discussion and collaboration
that we grow, and through growth that we improve.
In the effort to create such a place, we hold to these values:
1. **Discrimination limits us.** This includes discrimination on the basis of
race, gender, sexual orientation, gender identity, age, nationality,
technology and any other arbitrary exclusion of a group of people.
2. **Boundaries honor us.** Your comfort levels are not everyones comfort
levels. Remember that, and if brought to your attention, heed it.
3. **We are our biggest assets.** None of us were born masters of our trade.
Each of us has been helped along the way. Return that favor, when and where
you can.
4. **We are resources for the future.** As an extension of #3, share what you
know. Make yourself a resource to help those that come after you.
5. **Respect defines us.** Treat others as you wish to be treated. Make your
discussions, criticisms and debates from a position of respectfulness. Ask
yourself, is it true? Is it necessary? Is it constructive? Anything less is
unacceptable.
6. **Reactions require grace.** Angry responses are valid, but abusive language
and vindictive actions are toxic. When something happens that offends you,
handle it assertively, but be respectful. Escalate reasonably, and try to
allow the offender an opportunity to explain themselves, and possibly
correct the issue.
7. **Opinions are just that: opinions.** Each and every one of us, due to our
background and upbringing, have varying opinions. That is perfectly
acceptable. Remember this: if you respect your own opinions, you should
respect the opinions of others.
8. **To err is human.** You might not intend it, but mistakes do happen and
contribute to build experience. Tolerate honest mistakes, and don't
hesitate to apologize if you make one yourself.

#### Support
If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
#### What to contribute
If you don't know what to do, there are some features and functions that need to be done
- [ ] Refactor code
- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
- [ ] Create actual list of contributors and projects that currently using this package
- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc
- [x] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224)
- [ ] Implement fuzzing testing
- [ ] Implement some struct/map/array utilities
- [ ] Implement map/array validation
- [ ] Implement benchmarking
- [ ] Implement batch of examples
- [ ] Look at forks for new features and fixes
#### Advice
Feel free to create what you want, but keep in mind when you implement new features:
- Code must be clear and readable, names of variables/constants clearly describes what they are doing
- Public functions must be documented and described in source file and added to README.md to the list of available functions
- There are must be unit-tests for any new functions and improvements
## Financial contributions
We also welcome financial contributions in full transparency on our [open collective](https://opencollective.com/govalidator).
Anyone can file an expense. If the expense makes sense for the development of the community, it will be "merged" in the ledger of our open collective by the core contributors and the person who filed the expense will be reimbursed.

A package of validators and sanitizers for strings, structs and collections. Based on [validator.js](https://github.com/chriso/validator.js).
#### Installation
Make sure that Go is installed on your computer.
Type the following command in your terminal:
go get github.com/asaskevich/govalidator
or you can get specified release of the package with `gopkg.in`:
go get gopkg.in/asaskevich/govalidator.v10
After it the package is ready to use.
#### Import package in your project
Add following line in your `*.go` file:
```go
import "github.com/asaskevich/govalidator"
```
If you are unhappy to use long `govalidator`, you can do something like this:
```go
import (
valid "github.com/asaskevich/govalidator"
)
```
#### Activate behavior to require all fields have a validation tag by default
`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
```go
import "github.com/asaskevich/govalidator"
func init() {
govalidator.SetFieldsRequiredByDefault(true)
}
```
Here's some code to explain it:
```go
// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
type exampleStruct struct {
Name string ``
Email string `valid:"email"`
}
// this, however, will only fail when Email is empty or an invalid email address:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email"`
}
// lastly, this will only fail when Email is an invalid email address but not when it's empty:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email,optional"`
}
```
#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
##### Custom validator function signature
A context was added as the second parameter, for structs this is the object being validated this makes dependent validation possible.
```go
import "github.com/asaskevich/govalidator"
// old signature
func(i interface{}) bool
// new signature
func(i interface{}, o interface{}) bool
```
##### Adding a custom validator
This was changed to prevent data races when accessing custom validators.
```go
import "github.com/asaskevich/govalidator"
// before
govalidator.CustomTypeTagMap["customByteArrayValidator"] = func(i interface{}, o interface{}) bool {
// ...
}
// after
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, o interface{}) bool {
// ...
})
```

#### Examples
###### IsURL
```go
println(govalidator.IsURL(`http://user@pass:domain.com/path/page`))
```
###### IsType
```go
println(govalidator.IsType("Bob", "string"))
println(govalidator.IsType(1, "int"))
i := 1
println(govalidator.IsType(&i, "*int"))
```
IsType can be used through the tag `type` which is essential for map validation:
```go
type User struct {
Name string `valid:"type(string)"`
Age int `valid:"type(int)"`
Meta interface{} `valid:"type(string)"`
}
result, err := govalidator.ValidateStruct(User{"Bob", 20, "meta"})
if err != nil {
println("error: " + err.Error())
}
println(result)
```
###### ToString
```go
type User struct {
FirstName string
LastName string
}
str := govalidator.ToString(&User{"John", "Juan"})
println(str)
```
###### Each, Map, Filter, Count for slices
Each iterates over the slice/array and calls Iterator for every item
```go
data := []interface{}{1, 2, 3, 4, 5}
var fn govalidator.Iterator = func(value interface{}, index int) {
println(value.(int))
}
govalidator.Each(data, fn)
```
```go
data := []interface{}{1, 2, 3, 4, 5}
var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
return value.(int) * 3
}
_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
```
```go
data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
return value.(int)%2 == 0
}
_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
_ = govalidator.Count(data, fn) // result = 5
```
###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
```go
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
return str == "duck"
})
```
For completely custom validators (interface-based), see below.
Here is a list of available validators for struct fields (validator - used function):
```go
"email": IsEmail,
"url": IsURL,
"dialstring": IsDialString,
"requrl": IsRequestURL,
"requri": IsRequestURI,
"alpha": IsAlpha,
"utfletter": IsUTFLetter,
"alphanum": IsAlphanumeric,
"utfletternum": IsUTFLetterNumeric,
"numeric": IsNumeric,
"utfnumeric": IsUTFNumeric,
"utfdigit": IsUTFDigit,
"hexadecimal": IsHexadecimal,
"hexcolor": IsHexcolor,
"rgbcolor": IsRGBcolor,
"lowercase": IsLowerCase,
"uppercase": IsUpperCase,
"int": IsInt,
"float": IsFloat,
"null": IsNull,
"uuid": IsUUID,
"uuidv3": IsUUIDv3,
"uuidv4": IsUUIDv4,
"uuidv5": IsUUIDv5,
"creditcard": IsCreditCard,
"isbn10": IsISBN10,
"isbn13": IsISBN13,
"json": IsJSON,
"multibyte": IsMultibyte,
"ascii": IsASCII,
"printableascii": IsPrintableASCII,
"fullwidth": IsFullWidth,
"halfwidth": IsHalfWidth,
"variablewidth": IsVariableWidth,
"base64": IsBase64,
"datauri": IsDataURI,
"ip": IsIP,
"port": IsPort,
"ipv4": IsIPv4,
"ipv6": IsIPv6,
"dns": IsDNSName,
"host": IsHost,
"mac": IsMAC,
"latitude": IsLatitude,
"longitude": IsLongitude,
"ssn": IsSSN,
"semver": IsSemver,
"rfc3339": IsRFC3339,
"rfc3339WithoutZone": IsRFC3339WithoutZone,
"ISO3166Alpha2": IsISO3166Alpha2,
"ISO3166Alpha3": IsISO3166Alpha3,
"ulid": IsULID,
```
Validators with parameters
```go
"range(min|max)": Range,
"length(min|max)": ByteLength,
"runelength(min|max)": RuneLength,
"stringlength(min|max)": StringLength,
"matches(pattern)": StringMatches,
"in(string1|string2|...|stringN)": IsIn,
"rsapub(keylength)" : IsRsaPub,
"minstringlength(int): MinStringLength,
"maxstringlength(int): MaxStringLength,
```
Validators with parameters for any type
```go
"type(type)": IsType,
```
And here is small example of usage:
```go
type Post struct {
Title string `valid:"alphanum,required"`
Message string `valid:"duck,ascii"`
Message2 string `valid:"animal(dog)"`
AuthorIP string `valid:"ipv4"`
Date string `valid:"-"`
}
post := &Post{
Title: "My Example Post",
Message: "duck",
Message2: "dog",
AuthorIP: "123.234.54.3",
}
// Add your own struct validation tags
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
return str == "duck"
})
// Add your own struct validation tags with parameter
govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool {
species := params[0]
return str == species
})
govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$")
result, err := govalidator.ValidateStruct(post)
if err != nil {
println("error: " + err.Error())
}
println(result)
```
###### ValidateMap [#2](https://github.com/asaskevich/govalidator/pull/338)
If you want to validate maps, you can use the map to be validated and a validation map that contain the same tags used in ValidateStruct, both maps have to be in the form `map[string]interface{}`
So here is small example of usage:
```go
var mapTemplate = map[string]interface{}{
"name":"required,alpha",
"family":"required,alpha",
"email":"required,email",
"cell-phone":"numeric",
"address":map[string]interface{}{
"line1":"required,alphanum",
"line2":"alphanum",
"postal-code":"numeric",
},
}
var inputMap = map[string]interface{}{
"name":"Bob",
"family":"Smith",
"email":"foo@bar.baz",
"address":map[string]interface{}{
"line1":"",
"line2":"",
"postal-code":"",
},
}
result, err := govalidator.ValidateMap(inputMap, mapTemplate)
if err != nil {
println("error: " + err.Error())
}
println(result)
```
###### WhiteList
```go
// Remove all characters from string ignoring characters between "a" and "z"
println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
```
###### Custom validation functions
Custom validation using your own domain specific validators is also available - here's an example of how to use it:
```go
import "github.com/asaskevich/govalidator"
type CustomByteArray [6]byte // custom types are supported and can be validated
type StructWithCustomByteArray struct {
ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
Email string `valid:"email"`
CustomMinLength int `valid:"-"`
}
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, context interface{}) bool {
switch v := context.(type) { // you can type switch on the context interface being validated
case StructWithCustomByteArray:
// you can check and validate against some other field in the context,
// return early or not validate against the context at all your choice
case SomeOtherType:
// ...
default:
// expecting some other type? Throw/panic here or continue
}
switch v := i.(type) { // type switch on the struct field being validated
case CustomByteArray:
for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
if e != 0 {
return true
}
}
}
return false
})
govalidator.CustomTypeTagMap.Set("customMinLengthValidator", func(i interface{}, context interface{}) bool {
switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
case StructWithCustomByteArray:
return len(v.ID) >= v.CustomMinLength
}
return false
})
```
###### Loop over Error()
By default .Error() returns all errors in a single String. To access each error you can do this:
```go
if err != nil {
errs := err.(govalidator.Errors).Errors()
for _, e := range errs {
fmt.Println(e.Error())
}
}
```
###### Custom error messages
Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
```go
type Ticket struct {
Id int64 `json:"id"`
FirstName string `json:"firstname" valid:"required~First name is blank"`
}
```

# xxhash
[![Go Reference](https://pkg.go.dev/badge/github.com/cespare/xxhash/v2.svg)](https://pkg.go.dev/github.com/cespare/xxhash/v2)
[![Test](https://github.com/cespare/xxhash/actions/workflows/test.yml/badge.svg)](https://github.com/cespare/xxhash/actions/workflows/test.yml)
xxhash is a Go implementation of the 64-bit [xxHash] algorithm, XXH64. This is a
high-quality hashing algorithm that is much faster than anything in the Go
standard library.
This package provides a straightforward API:
```
func Sum64(b []byte) uint64
func Sum64String(s string) uint64
type Digest struct{ ... }
func New() *Digest
```
The `Digest` type implements hash.Hash64. Its key methods are:
```
func (*Digest) Write([]byte) (int, error)
func (*Digest) WriteString(string) (int, error)
func (*Digest) Sum64() uint64
```
The package is written with optimized pure Go and also contains even faster
assembly implementations for amd64 and arm64. If desired, the `purego` build tag
opts into using the Go code even on those architectures.
[xxHash]: http://cyan4973.github.io/xxHash/
## Compatibility
This package is in a module and the latest code is in version 2 of the module.
You need a version of Go with at least "minimal module compatibility" to use
github.com/cespare/xxhash/v2:
* 1.9.7+ for Go 1.9
* 1.10.3+ for Go 1.10
* Go 1.11 or later
I recommend using the latest release of Go.
## Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly
implementations of Sum64.
| input size | purego | asm |
| ---------- | --------- | --------- |
| 4 B | 1.3 GB/s | 1.2 GB/s |
| 16 B | 2.9 GB/s | 3.5 GB/s |
| 100 B | 6.9 GB/s | 8.1 GB/s |
| 4 KB | 11.7 GB/s | 16.7 GB/s |
| 10 MB | 12.0 GB/s | 17.3 GB/s |
These numbers were generated on Ubuntu 20.04 with an Intel Xeon Platinum 8252C
CPU using the following commands under Go 1.19.2:
```
benchstat <(go test -tags purego -benchtime 500ms -count 15 -bench 'Sum64$')
benchstat <(go test -benchtime 500ms -count 15 -bench 'Sum64$')
```

# A minimal logging API for Go
[![Go Reference](https://pkg.go.dev/badge/github.com/go-logr/logr.svg)](https://pkg.go.dev/github.com/go-logr/logr)
[![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/go-logr/logr/badge)](https://securityscorecards.dev/viewer/?platform=github.com&org=go-logr&repo=logr)
logr offers an(other) opinion on how Go programs and libraries can do logging
without becoming coupled to a particular logging implementation. This is not
an implementation of logging - it is an API. In fact it is two APIs with two
different sets of users.
The `Logger` type is intended for application and library authors. It provides
a relatively small API which can be used everywhere you want to emit logs. It
defers the actual act of writing logs (to files, to stdout, or whatever) to the
`LogSink` interface.
The `LogSink` interface is intended for logging library implementers. It is a
pure interface which can be implemented by logging frameworks to provide the actual logging
functionality.
This decoupling allows application and library developers to write code in
terms of `logr.Logger` (which has very low dependency fan-out) while the
implementation of logging is managed "up stack" (e.g. in or near `main()`.)
Application developers can then switch out implementations as necessary.
Many people assert that libraries should not be logging, and as such efforts
like this are pointless. Those people are welcome to convince the authors of
the tens-of-thousands of libraries that *DO* write logs that they are all
wrong. In the meantime, logr takes a more practical approach.
## Typical usage
Somewhere, early in an application's life, it will make a decision about which
logging library (implementation) it actually wants to use. Something like:
```
func main() {
// ... other setup code ...
// Create the "root" logger. We have chosen the "logimpl" implementation,
// which takes some initial parameters and returns a logr.Logger.
logger := logimpl.New(param1, param2)
// ... other setup code ...
```
Most apps will call into other libraries, create structures to govern the flow,
etc. The `logr.Logger` object can be passed to these other libraries, stored
in structs, or even used as a package-global variable, if needed. For example:
```
app := createTheAppObject(logger)
app.Run()
```
Outside of this early setup, no other packages need to know about the choice of
implementation. They write logs in terms of the `logr.Logger` that they
received:
```
type appObject struct {
// ... other fields ...
logger logr.Logger
// ... other fields ...
}
func (app *appObject) Run() {
app.logger.Info("starting up", "timestamp", time.Now())
// ... app code ...
```
## Background
If the Go standard library had defined an interface for logging, this project
probably would not be needed. Alas, here we are.
When the Go developers started developing such an interface with
[slog](https://github.com/golang/go/issues/56345), they adopted some of the
logr design but also left out some parts and changed others:
| Feature | logr | slog |
|---------|------|------|
| High-level API | `Logger` (passed by value) | `Logger` (passed by [pointer](https://github.com/golang/go/issues/59126)) |
| Low-level API | `LogSink` | `Handler` |
| Stack unwinding | done by `LogSink` | done by `Logger` |
| Skipping helper functions | `WithCallDepth`, `WithCallStackHelper` | [not supported by Logger](https://github.com/golang/go/issues/59145) |
| Generating a value for logging on demand | `Marshaler` | `LogValuer` |
| Log levels | >= 0, higher meaning "less important" | positive and negative, with 0 for "info" and higher meaning "more important" |
| Error log entries | always logged, don't have a verbosity level | normal log entries with level >= `LevelError` |
| Passing logger via context | `NewContext`, `FromContext` | no API |
| Adding a name to a logger | `WithName` | no API |
| Modify verbosity of log entries in a call chain | `V` | no API |
| Grouping of key/value pairs | not supported | `WithGroup`, `GroupValue` |
| Pass context for extracting additional values | no API | API variants like `InfoCtx` |
The high-level slog API is explicitly meant to be one of many different APIs
that can be layered on top of a shared `slog.Handler`. logr is one such
alternative API, with [interoperability](#slog-interoperability) provided by
some conversion functions.
### Inspiration
Before you consider this package, please read [this blog post by the
inimitable Dave Cheney][warning-makes-no-sense]. We really appreciate what
he has to say, and it largely aligns with our own experiences.
### Differences from Dave's ideas
The main differences are:
1. Dave basically proposes doing away with the notion of a logging API in favor
of `fmt.Printf()`. We disagree, especially when you consider things like output
locations, timestamps, file and line decorations, and structured logging. This
package restricts the logging API to just 2 types of logs: info and error.
Info logs are things you want to tell the user which are not errors. Error
logs are, well, errors. If your code receives an `error` from a subordinate
function call and is logging that `error` *and not returning it*, use error
logs.
2. Verbosity-levels on info logs. This gives developers a chance to indicate
arbitrary grades of importance for info logs, without assigning names with
semantic meaning such as "warning", "trace", and "debug." Superficially this
may feel very similar, but the primary difference is the lack of semantics.
Because verbosity is a numerical value, it's safe to assume that an app running
with higher verbosity means more (and less important) logs will be generated.
## Implementations (non-exhaustive)
There are implementations for the following logging libraries:
- **a function** (can bridge to non-structured libraries): [funcr](https://github.com/go-logr/logr/tree/master/funcr)
- **a testing.T** (for use in Go tests, with JSON-like output): [testr](https://github.com/go-logr/logr/tree/master/testr)
- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr)
- **k8s.io/klog** (for Kubernetes): [klogr](https://git.k8s.io/klog/klogr)
- **a testing.T** (with klog-like text output): [ktesting](https://git.k8s.io/klog/ktesting)
- **go.uber.org/zap**: [zapr](https://github.com/go-logr/zapr)
- **log** (the Go standard library logger): [stdr](https://github.com/go-logr/stdr)
- **github.com/sirupsen/logrus**: [logrusr](https://github.com/bombsimon/logrusr)
- **github.com/wojas/genericr**: [genericr](https://github.com/wojas/genericr) (makes it easy to implement your own backend)
- **logfmt** (Heroku style [logging](https://www.brandur.org/logfmt)): [logfmtr](https://github.com/iand/logfmtr)
- **github.com/rs/zerolog**: [zerologr](https://github.com/go-logr/zerologr)
- **github.com/go-kit/log**: [gokitlogr](https://github.com/tonglil/gokitlogr) (also compatible with github.com/go-kit/kit/log since v0.12.0)
- **bytes.Buffer** (writing to a buffer): [bufrlogr](https://github.com/tonglil/buflogr) (useful for ensuring values were logged, like during testing)
## slog interoperability
Interoperability goes both ways, using the `logr.Logger` API with a `slog.Handler`
and using the `slog.Logger` API with a `logr.LogSink`. `FromSlogHandler` and
`ToSlogHandler` convert between a `logr.Logger` and a `slog.Handler`.
As usual, `slog.New` can be used to wrap such a `slog.Handler` in the high-level
slog API.
### Using a `logr.LogSink` as backend for slog
Ideally, a logr sink implementation should support both logr and slog by
implementing both the normal logr interface(s) and `SlogSink`. Because
of a conflict in the parameters of the common `Enabled` method, it is [not
possible to implement both slog.Handler and logr.Sink in the same
type](https://github.com/golang/go/issues/59110).
If both are supported, log calls can go from the high-level APIs to the backend
without the need to convert parameters. `FromSlogHandler` and `ToSlogHandler` can
convert back and forth without adding additional wrappers, with one exception:
when `Logger.V` was used to adjust the verbosity for a `slog.Handler`, then
`ToSlogHandler` has to use a wrapper which adjusts the verbosity for future
log calls.
Such an implementation should also support values that implement specific
interfaces from both packages for logging (`logr.Marshaler`, `slog.LogValuer`,
`slog.GroupValue`). logr does not convert those.
Not supporting slog has several drawbacks:
- Recording source code locations works correctly if the handler gets called
through `slog.Logger`, but may be wrong in other cases. That's because a
`logr.Sink` does its own stack unwinding instead of using the program counter
provided by the high-level API.
- slog levels <= 0 can be mapped to logr levels by negating the level without a
loss of information. But all slog levels > 0 (e.g. `slog.LevelWarning` as
used by `slog.Logger.Warn`) must be mapped to 0 before calling the sink
because logr does not support "more important than info" levels.
- The slog group concept is supported by prefixing each key in a key/value
pair with the group names, separated by a dot. For structured output like
JSON it would be better to group the key/value pairs inside an object.
- Special slog values and interfaces don't work as expected.
- The overhead is likely to be higher.
These drawbacks are severe enough that applications using a mixture of slog and
logr should switch to a different backend.
### Using a `slog.Handler` as backend for logr
Using a plain `slog.Handler` without support for logr works better than the
other direction:
- All logr verbosity levels can be mapped 1:1 to their corresponding slog level
by negating them.
- Stack unwinding is done by the `SlogSink` and the resulting program
counter is passed to the `slog.Handler`.
- Names added via `Logger.WithName` are gathered and recorded in an additional
attribute with `logger` as key and the names separated by slash as value.
- `Logger.Error` is turned into a log record with `slog.LevelError` as level
and an additional attribute with `err` as key, if an error was provided.
The main drawback is that `logr.Marshaler` will not be supported. Types should
ideally support both `logr.Marshaler` and `slog.Valuer`. If compatibility
with logr implementations without slog support is not important, then
`slog.Valuer` is sufficient.
### Context support for slog
Storing a logger in a `context.Context` is not supported by
slog. `NewContextWithSlogLogger` and `FromContextAsSlogLogger` can be
used to fill this gap. They store and retrieve a `slog.Logger` pointer
under the same context key that is also used by `NewContext` and
`FromContext` for `logr.Logger` value.
When `NewContextWithSlogLogger` is followed by `FromContext`, the latter will
automatically convert the `slog.Logger` to a
`logr.Logger`. `FromContextAsSlogLogger` does the same for the other direction.
With this approach, binaries which use either slog or logr are as efficient as
possible with no unnecessary allocations. This is also why the API stores a
`slog.Logger` pointer: when storing a `slog.Handler`, creating a `slog.Logger`
on retrieval would need to allocate one.
The downside is that switching back and forth needs more allocations. Because
logr is the API that is already in use by different packages, in particular
Kubernetes, the recommendation is to use the `logr.Logger` API in code which
uses contextual logging.
An alternative to adding values to a logger and storing that logger in the
context is to store the values in the context and to configure a logging
backend to extract those values when emitting log entries. This only works when
log calls are passed the context, which is not supported by the logr API.
With the slog API, it is possible, but not
required. https://github.com/veqryn/slog-context is a package for slog which
provides additional support code for this approach. It also contains wrappers
for the context functions in logr, so developers who prefer to not use the logr
APIs directly can use those instead and the resulting code will still be
interoperable with logr.
## FAQ
### Conceptual
#### Why structured logging?
- **Structured logs are more easily queryable**: Since you've got
key-value pairs, it's much easier to query your structured logs for
particular values by filtering on the contents of a particular key --
think searching request logs for error codes, Kubernetes reconcilers for
the name and namespace of the reconciled object, etc.
- **Structured logging makes it easier to have cross-referenceable logs**:
Similarly to searchability, if you maintain conventions around your
keys, it becomes easy to gather all log lines related to a particular
concept.
- **Structured logs allow better dimensions of filtering**: if you have
structure to your logs, you've got more precise control over how much
information is logged -- you might choose in a particular configuration
to log certain keys but not others, only log lines where a certain key
matches a certain value, etc., instead of just having v-levels and names
to key off of.
- **Structured logs better represent structured data**: sometimes, the
data that you want to log is inherently structured (think tuple-link
objects.) Structured logs allow you to preserve that structure when
outputting.
#### Why V-levels?
**V-levels give operators an easy way to control the chattiness of log
operations**. V-levels provide a way for a given package to distinguish
the relative importance or verbosity of a given log message. Then, if
a particular logger or package is logging too many messages, the user
of the package can simply change the v-levels for that library.
#### Why not named levels, like Info/Warning/Error?
Read [Dave Cheney's post][warning-makes-no-sense]. Then read [Differences
from Dave's ideas](#differences-from-daves-ideas).
#### Why not allow format strings, too?
**Format strings negate many of the benefits of structured logs**:
- They're not easily searchable without resorting to fuzzy searching,
regular expressions, etc.
- They don't store structured data well, since contents are flattened into
a string.
- They're not cross-referenceable.
- They don't compress easily, since the message is not constant.
(Unless you turn positional parameters into key-value pairs with numerical
keys, at which point you've gotten key-value logging with meaningless
keys.)
### Practical
#### Why key-value pairs, and not a map?
Key-value pairs are *much* easier to optimize, especially around
allocations. Zap (a structured logger that inspired logr's interface) has
[performance measurements](https://github.com/uber-go/zap#performance)
that show this quite nicely.
While the interface ends up being a little less obvious, you get
potentially better performance, plus avoid making users type
`map[string]string{}` every time they want to log.
#### What if my V-levels differ between libraries?
That's fine. Control your V-levels on a per-logger basis, and use the
`WithName` method to pass different loggers to different libraries.
Generally, you should take care to ensure that you have relatively
consistent V-levels within a given logger, however, as this makes deciding
on what verbosity of logs to request easier.
#### But I really want to use a format string!
That's not actually a question. Assuming your question is "how do
I convert my mental model of logging with format strings to logging with
constant messages":
1. Figure out what the error actually is, as you'd write in a TL;DR style,
and use that as a message.
2. For every place you'd write a format specifier, look to the word before
it, and add that as a key value pair.
For instance, consider the following examples (all taken from spots in the
Kubernetes codebase):
- `klog.V(4).Infof("Client is returning errors: code %v, error %v",
responseCode, err)` becomes `logger.Error(err, "client returned an
error", "code", responseCode)`
- `klog.V(4).Infof("Got a Retry-After %ds response for attempt %d to %v",
seconds, retries, url)` becomes `logger.V(4).Info("got a retry-after
response when requesting url", "attempt", retries, "after
seconds", seconds, "url", url)`
If you *really* must use a format string, use it in a key's value, and
call `fmt.Sprintf` yourself. For instance: `log.Printf("unable to
reflect over type %T")` becomes `logger.Info("unable to reflect over
type", "type", fmt.Sprintf("%T"))`. In general though, the cases where
this is necessary should be few and far between.
#### How do I choose my V-levels?
This is basically the only hard constraint: increase V-levels to denote
more verbose or more debug-y logs.
Otherwise, you can start out with `0` as "you always want to see this",
`1` as "common logging that you might *possibly* want to turn off", and
`10` as "I would like to performance-test your log collection stack."
Then gradually choose levels in between as you need them, working your way
down from 10 (for debug and trace style logs) and up from 1 (for chattier
info-type logs). For reference, slog pre-defines -4 for debug logs
(corresponds to 4 in logr), which matches what is
[recommended for Kubernetes](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/logging.md#what-method-to-use).
#### How do I choose my keys?
Keys are fairly flexible, and can hold more or less any string
value. For best compatibility with implementations and consistency
with existing code in other projects, there are a few conventions you
should consider.
- Make your keys human-readable.
- Constant keys are generally a good idea.
- Be consistent across your codebase.
- Keys should naturally match parts of the message string.
- Use lower case for simple keys and
[lowerCamelCase](https://en.wiktionary.org/wiki/lowerCamelCase) for
more complex ones. Kubernetes is one example of a project that has
[adopted that
convention](https://github.com/kubernetes/community/blob/HEAD/contributors/devel/sig-instrumentation/migration-to-structured-logging.md#name-arguments).
While key names are mostly unrestricted (and spaces are acceptable),
it's generally a good idea to stick to printable ascii characters, or at
least match the general character set of your log lines.
#### Why should keys be constant values?
The point of structured logging is to make later log processing easier. Your
keys are, effectively, the schema of each log message. If you use different
keys across instances of the same log line, you will make your structured logs
much harder to use. `Sprintf()` is for values, not for keys!
#### Why is this not a pure interface?
The Logger type is implemented as a struct in order to allow the Go compiler to
optimize things like high-V `Info` logs that are not triggered. Not all of
these implementations are implemented yet, but this structure was suggested as
a way to ensure they *can* be implemented. All of the real work is behind the
`LogSink` interface.

# Security Policy
If you have discovered a security vulnerability in this project, please report it
privately. **Do not disclose it as a public issue.** This gives us time to work with you
to fix the issue before public exposure, reducing the chance that the exploit will be
used before a patch is released.
You may submit the report in the following ways:
- send an email to go-logr-security@googlegroups.com
- send us a [private vulnerability report](https://github.com/go-logr/logr/security/advisories/new)
Please provide the following information in your report:
- A description of the vulnerability and its impact
- How to reproduce the issue
We ask that you give us 90 days to work on a fix before public exposure.

// This design derives from Dave Cheney's blog:
// http://dave.cheney.net/2015/11/05/lets-talk-about-logging
// Package logr defines a general-purpose logging API and abstract interfaces
// to back that API. Packages in the Go ecosystem can depend on this package,
// while callers can implement logging with whatever backend is appropriate.
//
// # Usage
//
// Logging is done using a Logger instance. Logger is a concrete type with
// methods, which defers the actual logging to a LogSink interface. The main
// methods of Logger are Info() and Error(). Arguments to Info() and Error()
// are key/value pairs rather than printf-style formatted strings, emphasizing
// "structured logging".
//
// With Go's standard log package, we might write:
//
// log.Printf("setting target value %s", targetValue)
//
// With logr's structured logging, we'd write:
//
// logger.Info("setting target", "value", targetValue)
//
// Errors are much the same. Instead of:
//
// log.Printf("failed to open the pod bay door for user %s: %v", user, err)
//
// We'd write:
//
// logger.Error(err, "failed to open the pod bay door", "user", user)
//
// Info() and Error() are very similar, but they are separate methods so that
// LogSink implementations can choose to do things like attach additional
// information (such as stack traces) on calls to Error(). Error() messages are
// always logged, regardless of the current verbosity. If there is no error
// instance available, passing nil is valid.
//
// # Verbosity
//
// Often we want to log information only when the application in "verbose
// mode". To write log lines that are more verbose, Logger has a V() method.
// The higher the V-level of a log line, the less critical it is considered.
// Log-lines with V-levels that are not enabled (as per the LogSink) will not
// be written. Level V(0) is the default, and logger.V(0).Info() has the same
// meaning as logger.Info(). Negative V-levels have the same meaning as V(0).
// Error messages do not have a verbosity level and are always logged.
//
// Where we might have written:
//
// if flVerbose >= 2 {
// log.Printf("an unusual thing happened")
// }
//
// We can write:
//
// logger.V(2).Info("an unusual thing happened")
//
// # Logger Names
//
// Logger instances can have name strings so that all messages logged through
// that instance have additional context. For example, you might want to add
// a subsystem name:
//
// logger.WithName("compactor").Info("started", "time", time.Now())
//
// The WithName() method returns a new Logger, which can be passed to
// constructors or other functions for further use. Repeated use of WithName()
// will accumulate name "segments". These name segments will be joined in some
// way by the LogSink implementation. It is strongly recommended that name
// segments contain simple identifiers (letters, digits, and hyphen), and do
// not contain characters that could muddle the log output or confuse the
// joining operation (e.g. whitespace, commas, periods, slashes, brackets,
// quotes, etc).
//
// # Saved Values
//
// Logger instances can store any number of key/value pairs, which will be
// logged alongside all messages logged through that instance. For example,
// you might want to create a Logger instance per managed object:
//
// With the standard log package, we might write:
//
// log.Printf("decided to set field foo to value %q for object %s/%s",
// targetValue, object.Namespace, object.Name)
//
// With logr we'd write:
//
// // Elsewhere: set up the logger to log the object name.
// obj.logger = mainLogger.WithValues(
// "name", obj.name, "namespace", obj.namespace)
//
// // later on...
// obj.logger.Info("setting foo", "value", targetValue)
//
// # Best Practices
//
// Logger has very few hard rules, with the goal that LogSink implementations
// might have a lot of freedom to differentiate. There are, however, some
// things to consider.
//
// The log message consists of a constant message attached to the log line.
// This should generally be a simple description of what's occurring, and should
// never be a format string. Variable information can then be attached using
// named values.
//
// Keys are arbitrary strings, but should generally be constant values. Values
// may be any Go value, but how the value is formatted is determined by the
// LogSink implementation.
//
// Logger instances are meant to be passed around by value. Code that receives
// such a value can call its methods without having to check whether the
// instance is ready for use.
//
// The zero logger (= Logger{}) is identical to Discard() and discards all log
// entries. Code that receives a Logger by value can simply call it, the methods
// will never crash. For cases where passing a logger is optional, a pointer to Logger
// should be used.
//
// # Key Naming Conventions
//
// Keys are not strictly required to conform to any specification or regex, but
// it is recommended that they:
// - be human-readable and meaningful (not auto-generated or simple ordinals)
// - be constant (not dependent on input data)
// - contain only printable characters
// - not contain whitespace or punctuation
// - use lower case for simple keys and lowerCamelCase for more complex ones
//
// These guidelines help ensure that log data is processed properly regardless
// of the log implementation. For example, log implementations will try to
// output JSON data or will store data for later database (e.g. SQL) queries.
//
// While users are generally free to use key names of their choice, it's
// generally best to avoid using the following keys, as they're frequently used
// by implementations:
// - "caller": the calling information (file/line) of a particular log line
// - "error": the underlying error value in the `Error` method
// - "level": the log level
// - "logger": the name of the associated logger
// - "msg": the log message
// - "stacktrace": the stack trace associated with a particular log line or
// error (often from the `Error` message)
// - "ts": the timestamp for a log line
//
// Implementations are encouraged to make use of these keys to represent the
// above concepts, when necessary (for example, in a pure-JSON output form, it
// would be necessary to represent at least message and timestamp as ordinary
// named values).
//
// # Break Glass
//
// Implementations may choose to give callers access to the underlying
// logging implementation. The recommended pattern for this is:
//
// // Underlier exposes access to the underlying logging implementation.
// // Since callers only have a logr.Logger, they have to know which
// // implementation is in use, so this interface is less of an abstraction
// // and more of way to test type conversion.
// type Underlier interface {
// GetUnderlying() <underlying-type>
// }
//
// Logger grants access to the sink to enable type assertions like this:
//
// func DoSomethingWithImpl(log logr.Logger) {
// if underlier, ok := log.GetSink().(impl.Underlier); ok {
// implLogger := underlier.GetUnderlying()
// ...
// }
// }
//
// Custom `With*` functions can be implemented by copying the complete
// Logger struct and replacing the sink in the copy:
//
// // WithFooBar changes the foobar parameter in the log sink and returns a
// // new logger with that modified sink. It does nothing for loggers where
// // the sink doesn't support that parameter.
// func WithFoobar(log logr.Logger, foobar int) logr.Logger {
// if foobarLogSink, ok := log.GetSink().(FoobarSink); ok {
// log = log.WithSink(foobarLogSink.WithFooBar(foobar))
// }
// return log
// }
//
// Don't use New to construct a new Logger with a LogSink retrieved from an
// existing Logger. Source code attribution might not work correctly and
// unexported fields in Logger get lost.
//
// Beware that the same LogSink instance may be shared by different logger
// instances. Calling functions that modify the LogSink will affect all of
// those.

// implementing LogSink, rather than end users. Passing a nil sink will create

# 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
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

A foundational library to analyze an OAI specification document for easier reasoning about the content.
## What's inside?
* An analyzer providing methods to walk the functional content of a specification
* A spec flattener producing a self-contained document bundle, while preserving `$ref`s
* A spec merger ("mixin") to merge several spec documents into a primary spec
* A spec "fixer" ensuring that response descriptions are non empty
[Documentation](https://pkg.go.dev/github.com/go-openapi/analysis)
## FAQ
* Does this library support OpenAPI 3?
> No.
> This package currently only supports OpenAPI 2.0 (aka Swagger 2.0).
> There is no plan to make it evolve toward supporting OpenAPI 3.x.
> This [discussion thread](https://github.com/go-openapi/spec/issues/21) relates the full story.
