## Structured argument parsing for Go
|
||||
|
||||
```shell
|
||||
go get github.com/alexflint/go-arg
|
||||
```
|
||||
|
||||
Declare the command line arguments your program accepts by defining a struct.
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
Foo string
|
||||
Bar bool
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Println(args.Foo, args.Bar)
|
||||
```
|
||||
|
||||
```shell
|
||||
$ ./example --foo=hello --bar
|
||||
hello true
|
||||
```
|
||||
|
||||
### Required arguments
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
ID int `arg:"required"`
|
||||
Timeout time.Duration
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
```
|
||||
|
||||
```shell
|
||||
$ ./example
|
||||
Usage: example --id ID [--timeout TIMEOUT]
|
||||
error: --id is required
|
||||
```
|
||||
|
||||
### Positional arguments
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
Input string `arg:"positional"`
|
||||
Output []string `arg:"positional"`
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Println("Input:", args.Input)
|
||||
fmt.Println("Output:", args.Output)
|
||||
```
|
||||
|
||||
```
|
||||
$ ./example src.txt x.out y.out z.out
|
||||
Input: src.txt
|
||||
Output: [x.out y.out z.out]
|
||||
```
|
||||
|
||||
### Environment variables
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
Workers int `arg:"env"`
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Println("Workers:", args.Workers)
|
||||
```
|
||||
|
||||
```
|
||||
$ WORKERS=4 ./example
|
||||
Workers: 4
|
||||
```
|
||||
|
||||
```
|
||||
$ WORKERS=4 ./example --workers=6
|
||||
Workers: 6
|
||||
```
|
||||
|
||||
You can also override the name of the environment variable:
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
Workers int `arg:"env:NUM_WORKERS"`
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Println("Workers:", args.Workers)
|
||||
```
|
||||
|
||||
```
|
||||
$ NUM_WORKERS=4 ./example
|
||||
Workers: 4
|
||||
```
|
||||
|
||||
### Usage strings
|
||||
```go
|
||||
var args struct {
|
||||
Input string `arg:"positional"`
|
||||
Output []string `arg:"positional"`
|
||||
Verbose bool `arg:"-v,help:verbosity level"`
|
||||
Dataset string `arg:"help:dataset to use"`
|
||||
Optimize int `arg:"-O,help:optimization level"`
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
```
|
||||
|
||||
```shell
|
||||
$ ./example -h
|
||||
Usage: [--verbose] [--dataset DATASET] [--optimize OPTIMIZE] [--help] INPUT [OUTPUT [OUTPUT ...]]
|
||||
|
||||
Positional arguments:
|
||||
INPUT
|
||||
OUTPUT
|
||||
|
||||
Options:
|
||||
--verbose, -v verbosity level
|
||||
--dataset DATASET dataset to use
|
||||
--optimize OPTIMIZE, -O OPTIMIZE
|
||||
optimization level
|
||||
--help, -h print this help message
|
||||
```
|
||||
|
||||
### Default values
|
||||
|
||||
```go
|
||||
var args struct {
|
||||
Foo string
|
||||
Bar bool
|
||||
}
|
||||
args.Foo = "default value"
|
||||
arg.MustParse(&args)
|
||||
```
|
||||
|
||||
### Arguments with multiple values
|
||||
```go
|
||||
var args struct {
|
||||
Database string
|
||||
IDs []int64
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Printf("Fetching the following IDs from %s: %q", args.Database, args.IDs)
|
||||
```
|
||||
|
||||
```shell
|
||||
./example -database foo -ids 1 2 3
|
||||
Fetching the following IDs from foo: [1 2 3]
|
||||
```
|
||||
|
||||
### Arguments that can be specified multiple times, mixed with positionals
|
||||
```go
|
||||
var args struct {
|
||||
Commands []string `arg:"-c,separate"`
|
||||
Files []string `arg:"-f,separate"`
|
||||
Databases []string `arg:"positional"`
|
||||
}
|
||||
```
|
||||
|
||||
```shell
|
||||
./example -c cmd1 db1 -f file1 db2 -c cmd2 -f file2 -f file3 db3 -c cmd3
|
||||
Commands: [cmd1 cmd2 cmd3]
|
||||
Files [file1 file2 file3]
|
||||
Databases [db1 db2 db3]
|
||||
```
|
||||
|
||||
### Custom validation
|
||||
```go
|
||||
var args struct {
|
||||
Foo string
|
||||
Bar string
|
||||
}
|
||||
p := arg.MustParse(&args)
|
||||
if args.Foo == "" && args.Bar == "" {
|
||||
p.Fail("you must provide one of --foo and --bar")
|
||||
}
|
||||
```
|
||||
|
||||
```shell
|
||||
./example
|
||||
Usage: samples [--foo FOO] [--bar BAR]
|
||||
error: you must provide one of --foo and --bar
|
||||
```
|
||||
|
||||
### Version strings
|
||||
|
||||
```go
|
||||
type args struct {
|
||||
...
|
||||
}
|
||||
|
||||
func (args) Version() string {
|
||||
return "someprogram 4.3.0"
|
||||
}
|
||||
|
||||
func main() {
|
||||
var args args
|
||||
arg.MustParse(&args)
|
||||
}
|
||||
```
|
||||
|
||||
```shell
|
||||
$ ./example --version
|
||||
someprogram 4.3.0
|
||||
```
|
||||
|
||||
### Embedded structs
|
||||
|
||||
The fields of embedded structs are treated just like regular fields:
|
||||
|
||||
```go
|
||||
|
||||
type DatabaseOptions struct {
|
||||
Host string
|
||||
Username string
|
||||
Password string
|
||||
}
|
||||
|
||||
type LogOptions struct {
|
||||
LogFile string
|
||||
Verbose bool
|
||||
}
|
||||
|
||||
func main() {
|
||||
var args struct {
|
||||
DatabaseOptions
|
||||
LogOptions
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
}
|
||||
```
|
||||
|
||||
As usual, any field tagged with `arg:"-"` is ignored.
|
||||
|
||||
### Custom parsing
|
||||
|
||||
You can implement your own argument parser by implementing `encoding.TextUnmarshaler`:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"strings"
|
||||
|
||||
"github.com/alexflint/go-arg"
|
||||
)
|
||||
|
||||
// Accepts command line arguments of the form "head.tail"
|
||||
type NameDotName struct {
|
||||
Head, Tail string
|
||||
}
|
||||
|
||||
func (n *NameDotName) UnmarshalText(b []byte) error {
|
||||
s := string(b)
|
||||
pos := strings.Index(s, ".")
|
||||
if pos == -1 {
|
||||
return fmt.Errorf("missing period in %s", s)
|
||||
}
|
||||
n.Head = s[:pos]
|
||||
n.Tail = s[pos+1:]
|
||||
return nil
|
||||
}
|
||||
|
||||
func main() {
|
||||
var args struct {
|
||||
Name *NameDotName
|
||||
}
|
||||
arg.MustParse(&args)
|
||||
fmt.Printf("%#v\n", args.Name)
|
||||
}
|
||||
```
|
||||
```shell
|
||||
$ ./example --name=foo.bar
|
||||
&main.NameDotName{Head:"foo", Tail:"bar"}
|
||||
|
||||
$ ./example --name=oops
|
||||
Usage: example [--name NAME]
|
||||
error: error processing --name: missing period in "oops"
|
||||
```
|
||||
|
||||
### Description strings
|
||||
|
||||
```go
|
||||
type args struct {
|
||||
Foo string
|
||||
}
|
||||
|
||||
func (args) Description() string {
|
||||
return "this program does this and that"
|
||||
}
|
||||
|
||||
func main() {
|
||||
var args args
|
||||
arg.MustParse(&args)
|
||||
}
|
||||
```
|
||||
|
||||
```shell
|
||||
$ ./example -h
|
||||
this program does this and that
|
||||
Usage: example [--foo FOO]
|
||||
|
||||
Options:
|
||||
--foo FOO
|
||||
--help, -h display this help and exit
|
||||
```
|
||||
|
||||
### Documentation
|
||||
|
||||
https://godoc.org/github.com/alexflint/go-arg
|
||||
|
||||
### Rationale
|
||||
|
||||
There are many command line argument parsing libraries for Go, including one in the standard library, so why build another?
|
||||
|
||||
The shortcomings of the `flag` library that ships in the standard library are well known. Positional arguments must preceed options, so `./prog x --foo=1` does what you expect but `./prog --foo=1 x` does not. Arguments cannot have both long (`--foo`) and short (`-f`) forms.
|
||||
|
||||
Many third-party argument parsing libraries are geared for writing sophisticated command line interfaces. The excellent `codegangsta/cli` is perfect for working with multiple sub-commands and nested flags, but is probably overkill for a simple script with a handful of flags.
|
||||
|
||||
The main idea behind `go-arg` is that Go already has an excellent way to describe data structures using Go structs, so there is no need to develop more levels of abstraction on top of this. Instead of one API to specify which arguments your program accepts, and then another API to get the values of those arguments, why not replace both with a single struct?

// Package arg parses command line arguments using the fields from a struct.
|
||||
//
|
||||
// For example,
|
||||
//
|
||||
// var args struct {
|
||||
// Iter int
|
||||
// Debug bool
|
||||
// }
|
||||
// arg.MustParse(&args)
|
||||
//
|
||||
// defines two command line arguments, which can be set using any of
|
||||
//
|
||||
// ./example --iter=1 --debug // debug is a boolean flag so its value is set to true
|
||||
// ./example -iter 1 // debug defaults to its zero value (false)
|
||||
// ./example --debug=true // iter defaults to its zero value (zero)
|
||||
//
|
||||
// The fastest way to see how to use go-arg is to read the examples below.
|
||||
//
|
||||
// Fields can be bool, string, any float type, or any signed or unsigned integer type.
|
||||
// They can also be slices of any of the above, or slices of pointers to any of the above.
|
||||
//
|
||||
// Tags can be specified using the `arg` package name:
|
||||
//
|
||||
// var args struct {
|
||||
// Input string `arg:"positional"`
|
||||
// Log string `arg:"positional,required"`
|
||||
// Debug bool `arg:"-d,help:turn on debug mode"`
|
||||
// RealMode bool `arg:"--real"
|
||||
// Wr io.Writer `arg:"-"`
|
||||
// }
|
||||
//
|
||||
// The valid tag strings are `positional`, `required`, and `help`. Further, any tag string
|
||||
// that starts with a single hyphen is the short form for an argument (e.g. `./example -d`),
|
||||
// and any tag string that starts with two hyphens is the long form for the argument
|
||||
// (instead of the field name). Fields can be excluded from processing with `arg:"-"`.

## Scalar parsing library
|
||||
|
||||
Scalar is a library for parsing strings into arbitrary scalars (integers,
|
||||
floats, strings, booleans, etc). It is helpful for tasks such as parsing
|
||||
strings passed as environment variables or command line arguments.
|
||||
|
||||
```shell
|
||||
go get github.com/alexflint/go-scalar
|
||||
```
|
||||
|
||||
The main API works as follows:
|
||||
|
||||
```go
|
||||
var value int
|
||||
err := scalar.Parse(&value, "123")
|
||||
```
|
||||
|
||||
There is also a variant that takes a `reflect.Value`:
|
||||
|
||||
```go
|
||||
var value int
|
||||
err := scalar.ParseValue(reflect.ValueOf(&value), "123")
|
||||
```

||||
logging, and so on. It can be used for both typical application log events,
|
||||
and log-structured data streams.
|
||||
|
||||
## Structured logging
|
||||
|
||||
Structured logging is, basically, conceding to the reality that logs are
|
||||
_data_, and warrant some level of schematic rigor. Using a stricter,
|
||||
key/value-oriented message format for our logs, containing contextual and
|
||||
semantic information, makes it much easier to get insight into the
|
||||
operational activity of the systems we build. Consequently, `package log` is
|
||||
of the strong belief that "[the benefits of structured logging outweigh the
|
||||
minimal effort involved](https://www.thoughtworks.com/radar/techniques/structured-logging)".
|
||||
|
||||
Migrating from unstructured to structured logging is probably a lot easier
|
||||
than you'd expect.
|
||||
|
||||
```go
|
||||
// Unstructured
|
||||
log.Printf("HTTP server listening on %s", addr)
|
||||
|
||||
// Structured
|
||||
logger.Log("transport", "HTTP", "addr", addr, "msg", "listening")
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Typical application logging
|
||||
|
||||
```go
|
||||
w := log.NewSyncWriter(os.Stderr)
|
||||
logger := log.NewLogfmtLogger(w)
|
||||
logger.Log("question", "what is the meaning of life?", "answer", 42)
|
||||
|
||||
// Output:
|
||||
// question="what is the meaning of life?" answer=42
|
||||
```
|
||||
|
||||
### Contextual Loggers
|
||||
|
||||
```go
|
||||
func main() {
|
||||
var logger log.Logger
|
||||
logger = log.NewLogfmtLogger(log.NewSyncWriter(os.Stderr))
|
||||
logger = log.With(logger, "instance_id", 123)
|
||||
|
||||
logger.Log("msg", "starting")
|
||||
NewWorker(log.With(logger, "component", "worker")).Run()
|
||||
NewSlacker(log.With(logger, "component", "slacker")).Run()
|
||||
}
|
||||
|
||||
// Output:
|
||||
// instance_id=123 msg=starting
|
||||
// instance_id=123 component=worker msg=running
|
||||
// instance_id=123 component=slacker msg=running
|
||||
```
|
||||
|
||||
### Interact with stdlib logger
|
||||
|
||||
Redirect stdlib logger to Go kit logger.
|
||||
|
||||
```go
|
||||
import (
|
||||
"os"
|
||||
stdlog "log"
|
||||
kitlog "github.com/go-kit/kit/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
logger := kitlog.NewJSONLogger(kitlog.NewSyncWriter(os.Stdout))
|
||||
stdlog.SetOutput(kitlog.NewStdlibAdapter(logger))
|
||||
stdlog.Print("I sure like pie")
|
||||
}
|
||||
|
||||
// Output:
|
||||
// {"msg":"I sure like pie","ts":"2016/01/01 12:34:56"}
|
||||
```
|
||||
|
||||
Or, if, for legacy reasons, you need to pipe all of your logging through the
|
||||
stdlib log package, you can redirect Go kit logger to the stdlib logger.
|
||||
|
||||
```go
|
||||
logger := kitlog.NewLogfmtLogger(kitlog.StdlibWriter{})
|
||||
logger.Log("legacy", true, "msg", "at least it's something")
|
||||
|
||||
// Output:
|
||||
// 2016/01/01 12:34:56 legacy=true msg="at least it's something"
|
||||
```
|
||||
|
||||
### Timestamps and callers
|
||||
|
||||
```go
|
||||
var logger log.Logger
|
||||
logger = log.NewLogfmtLogger(log.NewSyncWriter(os.Stderr))
|
||||
logger = log.With(logger, "ts", log.DefaultTimestampUTC, "caller", log.DefaultCaller)
|
||||
|
||||
logger.Log("msg", "hello")
|
||||
|
||||
// Output:
|
||||
// ts=2016-01-01T12:34:56Z caller=main.go:15 msg=hello
|
||||
```
|
||||
|
||||
## Supported output formats
|
||||
|
||||
- [Logfmt](https://brandur.org/logfmt) ([see also](https://blog.codeship.com/logfmt-a-log-format-thats-easy-to-read-and-write))
|
||||
- JSON
|
||||
|
||||
## Enhancements
|
||||
|
||||
`package log` is centered on the one-method Logger interface.
|
||||
|
||||
```go
|
||||
type Logger interface {
|
||||
Log(keyvals ...interface{}) error
|
||||
}
|
||||
```
|
||||
|
||||
This interface, and its supporting code like is the product of much iteration
|
||||
and evaluation. For more details on the evolution of the Logger interface,
|
||||
see [The Hunt for a Logger Interface](http://go-talks.appspot.com/github.com/ChrisHines/talks/structured-logging/structured-logging.slide#1),
|
||||
a talk by [Chris Hines](https://github.com/ChrisHines).
|
||||

|
||||
[#252](https://github.com/go-kit/kit/pull/252)
|
||||
to review historical conversations about package log and the Logger interface.
|
||||
|
||||
Value-add packages and suggestions,
|
||||
like improvements to [the leveled logger](https://godoc.org/github.com/go-kit/kit/log/level),
|
||||
are of course welcome. Good proposals should
|
||||
|
||||
- Be composable with [contextual loggers](https://godoc.org/github.com/go-kit/kit/log#With),
|
||||
- Not break the behavior of [log.Caller](https://godoc.org/github.com/go-kit/kit/log#Caller) in any wrapped contextual loggers, and
|
||||
- Be friendly to packages that accept only an unadorned log.Logger.
|
||||
|
||||
## Benchmarks & comparisons
|
||||
|
||||
There are a few Go logging benchmarks and comparisons that include Go kit's package log.
|
||||
|
||||
- [imkira/go-loggers-bench](https://github.com/imkira/go-loggers-bench) includes kit/log
|
||||
- [uber-common/zap](https://github.com/uber-common/zap), a zero-alloc logging library, includes a comparison with kit/log

// Package log provides a structured logger.
|
||||
//
|
||||
// Structured logging produces logs easily consumed later by humans or
|
||||
// machines. Humans might be interested in debugging errors, or tracing
|
||||
// specific requests. Machines might be interested in counting interesting
|
||||
// events, or aggregating information for off-line processing. In both cases,
|
||||
// it is important that the log messages are structured and actionable.
|
||||
// Package log is designed to encourage both of these best practices.
|
||||
//
|
||||
// Basic Usage
|
||||
//
|
||||
// The fundamental interface is Logger. Loggers create log events from
|
||||
// key/value data. The Logger interface has a single method, Log, which
|
||||
// accepts a sequence of alternating key/value pairs, which this package names
|
||||
// keyvals.
|
||||
//
|
||||
// type Logger interface {
|
||||
// Log(keyvals ...interface{}) error
|
||||
// }
|
||||
//
|
||||
// Here is an example of a function using a Logger to create log events.
|
||||
//
|
||||
// func RunTask(task Task, logger log.Logger) string {
|
||||
// logger.Log("taskID", task.ID, "event", "starting task")
|
||||
// ...
|
||||
// logger.Log("taskID", task.ID, "event", "task complete")
|
||||
// }
|
||||
//
|
||||
// The keys in the above example are "taskID" and "event". The values are
|
||||
// task.ID, "starting task", and "task complete". Every key is followed
|
||||
// immediately by its value.
|
||||
//
|
||||
// Keys are usually plain strings. Values may be any type that has a sensible
|
||||
// encoding in the chosen log format. With structured logging it is a good
|
||||
// idea to log simple values without formatting them. This practice allows
|
||||
// the chosen logger to encode values in the most appropriate way.
|
||||
//
|
||||
// Contextual Loggers
|
||||
//
|
||||
// A contextual logger stores keyvals that it includes in all log events.
|
||||
// Building appropriate contextual loggers reduces repetition and aids
|
||||
// consistency in the resulting log output. With and WithPrefix add context to
|
||||
// a logger. We can use With to improve the RunTask example.
|
||||
//
|
||||
// func RunTask(task Task, logger log.Logger) string {
|
||||
// logger = log.With(logger, "taskID", task.ID)
|
||||
// logger.Log("event", "starting task")
|
||||
// ...
|
||||
// taskHelper(task.Cmd, logger)
|
||||
// ...
|
||||
// logger.Log("event", "task complete")
|
||||
// }
|
||||
//
|
||||
// The improved version emits the same log events as the original for the
|
||||
// first and last calls to Log. Passing the contextual logger to taskHelper
|
||||
// enables each log event created by taskHelper to include the task.ID even
|
||||
// though taskHelper does not have access to that value. Using contextual
|
||||
// loggers this way simplifies producing log output that enables tracing the
|
||||
// life cycle of individual tasks. (See the Contextual example for the full
|
||||
// code of the above snippet.)
|
||||
//
|
||||
// Dynamic Contextual Values
|
||||
//
|
||||
// A Valuer function stored in a contextual logger generates a new value each
|
||||
// time an event is logged. The Valuer example demonstrates how this feature
|
||||
// works.
|
||||
//
|
||||
// Valuers provide the basis for consistently logging timestamps and source
|
||||
// code location. The log package defines several valuers for that purpose.
|
||||
// See Timestamp, DefaultTimestamp, DefaultTimestampUTC, Caller, and
|
||||
// DefaultCaller. A common logger initialization sequence that ensures all log
|
||||
// entries contain a timestamp and source location looks like this:
|
||||
//
|
||||
// logger := log.NewLogfmtLogger(log.NewSyncWriter(os.Stdout))
|
||||
// logger = log.With(logger, "ts", log.DefaultTimestampUTC, "caller", log.DefaultCaller)
|
||||
//
|
||||
// Concurrent Safety
|
||||
//
|
||||
// Applications with multiple goroutines want each log event written to the
|
||||
// same logger to remain separate from other log events. Package log provides
|
||||
// two simple solutions for concurrent safe logging.
|
||||
//
|
||||
// NewSyncWriter wraps an io.Writer and serializes each call to its Write
|
||||
// method. Using a SyncWriter has the benefit that the smallest practical
|
||||
// portion of the logging logic is performed within a mutex, but it requires
|
||||
// the formatting Logger to make only one call to Write per log event.
|
||||
//
|
||||
// NewSyncLogger wraps any Logger and serializes each call to its Log method.
|
||||
// Using a SyncLogger has the benefit that it guarantees each log event is
|
||||
// handled atomically within the wrapped logger, but it typically serializes
|
||||
// both the formatting and output logic. Use a SyncLogger if the formatting
|
||||
// logger may perform multiple writes per log event.
|
||||
//
|
||||
// Error Handling
|
||||
//
|
||||
// This package relies on the practice of wrapping or decorating loggers with
|
||||
// other loggers to provide composable pieces of functionality. It also means
|
||||
// that Logger.Log must return an error because some
|
||||
// implementations—especially those that output log data to an io.Writer—may
|
||||
// encounter errors that cannot be handled locally. This in turn means that
|
||||
// Loggers that wrap other loggers should return errors from the wrapped
|
||||
// logger up the stack.
|
||||
//
|
||||
// Fortunately, the decorator pattern also provides a way to avoid the
|
||||
// necessity to check for errors every time an application calls Logger.Log.
|
||||
// An application required to panic whenever its Logger encounters
|
||||
// an error could initialize its logger as follows.
|
||||
//
|
||||
// fmtlogger := log.NewLogfmtLogger(log.NewSyncWriter(os.Stdout))
|
||||
// logger := log.LoggerFunc(func(keyvals ...interface{}) error {
|
||||
// if err := fmtlogger.Log(keyvals...); err != nil {
|
||||
// panic(err)
|
||||
// }
|
||||
// return nil
|
||||
// })

# logfmt
|
||||
|
||||
Package logfmt implements utilities to marshal and unmarshal data in the [logfmt
|
||||
format](https://brandur.org/logfmt). It provides an API similar to
|
||||
[encoding/json](http://golang.org/pkg/encoding/json/) and
|
||||
[encoding/xml](http://golang.org/pkg/encoding/xml/).
|
||||
|
||||
The logfmt format was first documented by Brandur Leach in [this
|
||||
article](https://brandur.org/logfmt). The format has not been formally
|
||||
standardized. The most authoritative public specification to date has been the
|
||||
documentation of a Go Language [package](http://godoc.org/github.com/kr/logfmt)
|
||||
written by Blake Mizerany and Keith Rarick.
|
||||
|
||||
## Goals
|
||||
|
||||
This project attempts to conform as closely as possible to the prior art, while
|
||||
also removing ambiguity where necessary to provide well behaved encoder and
|
||||
decoder implementations.
|
||||
|
||||
## Non-goals
|
||||
|
||||
This project does not attempt to formally standardize the logfmt format. In the
|
||||
event that logfmt is standardized this project would take conforming to the
|
||||
standard as a goal.
|
||||
|
||||
## Versioning
|
||||
|
||||
Package logfmt publishes releases via [semver](http://semver.org/) compatible Git tags prefixed with a single 'v'.

# stack
|
||||
|
||||
Package stack implements utilities to capture, manipulate, and format call
|
||||
stacks. It provides a simpler API than package runtime.
|
||||
|
||||
The implementation takes care of the minutia and special cases of interpreting
|
||||
the program counter (pc) values returned by runtime.Callers.
|
||||
|
||||
## Versioning
|
||||
|
||||
Package stack publishes releases via [semver](http://semver.org/) compatible Git
|
||||
tags prefixed with a single 'v'. The master branch always contains the latest
|
||||
release. The develop branch contains unreleased commits.
|
||||
|
||||
## Formatting
|
||||
|
||||
Package stack's types implement fmt.Formatter, which provides a simple and
|
||||
flexible way to declaratively configure formatting when used with logging or
|
||||
error tracking packages.
|
||||
|
||||
```go
|
||||
func DoTheThing() {
|
||||
c := stack.Caller(0)
|
||||
log.Print(c) // "source.go:10"
|
||||
log.Printf("%+v", c) // "pkg/path/source.go:10"
|
||||
log.Printf("%n", c) // "DoTheThing"
|
||||
|
||||
s := stack.Trace().TrimRuntime()
|
||||
log.Print(s) // "[source.go:15 caller.go:42 main.go:14]"
|
||||
}
|
||||
```
|
||||
|
||||
See the docs for all of the supported formatting options.

Equal returns true iff protocol buffers a and b are equal.
|
||||
The arguments must both be pointers to protocol buffer structs.
|
||||
|
||||
Equality is defined in this way:
|
||||
- Two messages are equal iff they are the same type,
|
||||
corresponding fields are equal, unknown field sets
|
||||
are equal, and extensions sets are equal.
|
||||
- Two set scalar fields are equal iff their values are equal.
|
||||
If the fields are of a floating-point type, remember that
|
||||
NaN != x for all x, including NaN. If the message is defined
|
||||
in a proto3 .proto file, fields are not "set"; specifically,
|
||||
zero length proto3 "bytes" fields are equal (nil == {}).
|
||||
- Two repeated fields are equal iff their lengths are the same,
|
||||
and their corresponding elements are equal. Note a "bytes" field,
|
||||
although represented by []byte, is not a repeated field and the
|
||||
rule for the scalar fields described above applies.
|
||||
- Two unset fields are equal.
|
||||
- Two unknown field sets are equal if their current
|
||||
encoded state is equal.
|
||||
- Two extension sets are equal iff they have corresponding
|
||||
elements that are pairwise equal.
|
||||
- Two map fields are equal iff their lengths are the same,
|
||||
and they contain the same set of elements. Zero-length map
|
||||
fields are equal.
|
||||
- Every other combination of things are not equal.
|
||||
|
||||
The return value is undefined if a and b are not protocol buffers.

/*
|
||||
Package proto converts data structures to and from the wire format of
|
||||
protocol buffers. It works in concert with the Go source code generated
|
||||
for .proto files by the protocol compiler.
|
||||
|
||||
A summary of the properties of the protocol buffer interface
|
||||
for a protocol buffer variable v:
|
||||
|
||||
- Names are turned from camel_case to CamelCase for export.
|
||||
- There are no methods on v to set fields; just treat
|
||||
them as structure fields.
|
||||
- There are getters that return a field's value if set,
|
||||
and return the field's default value if unset.
|
||||
The getters work even if the receiver is a nil message.
|
||||
- The zero value for a struct is its correct initialization state.
|
||||
All desired fields must be set before marshaling.
|
||||
- A Reset() method will restore a protobuf struct to its zero state.
|
||||
- Non-repeated fields are pointers to the values; nil means unset.
|
||||
That is, optional or required field int32 f becomes F *int32.
|
||||
- Repeated fields are slices.
|
||||
- Helper functions are available to aid the setting of fields.
|
||||
msg.Foo = proto.String("hello") // set field
|
||||
- Constants are defined to hold the default values of all fields that
|
||||
have them. They have the form Default_StructName_FieldName.
|
||||
Because the getter methods handle defaulted values,
|
||||
direct use of these constants should be rare.
|
||||
- Enums are given type names and maps from names to values.
|
||||
Enum values are prefixed by the enclosing message's name, or by the
|
||||
enum's type name if it is a top-level enum. Enum types have a String
|
||||
method, and a Enum method to assist in message construction.
|
||||
- Nested messages, groups and enums have type names prefixed with the name of
|
||||
the surrounding message type.
|
||||
- Extensions are given descriptor names that start with E_,
|
||||
followed by an underscore-delimited list of the nested messages
|
||||
that contain it (if any) followed by the CamelCased name of the
|
||||
extension field itself. HasExtension, ClearExtension, GetExtension
|
||||
and SetExtension are functions for manipulating extensions.
|
||||
- Oneof field sets are given a single field in their message,
|
||||
with distinguished wrapper types for each possible field value.
|
||||
- Marshal and Unmarshal are functions to encode and decode the wire format.
|
||||
|
||||
When the .proto file specifies `syntax="proto3"`, there are some differences:
|
||||
|
||||
- Non-repeated fields of non-message type are values instead of pointers.
|
||||
- Enum types do not get an Enum method.
|
||||
|
||||
The simplest way to describe this is to see an example.
|
||||
Given file test.proto, containing
|
||||
|
||||
package example;
|
||||
|
||||
enum FOO { X = 17; }
|
||||
|
||||
message Test {
|
||||
required string label = 1;
|
||||
optional int32 type = 2 [default=77];
|
||||
repeated int64 reps = 3;
|
||||
optional group OptionalGroup = 4 {
|
||||
required string RequiredField = 5;
|
||||
}
|
||||
oneof union {
|
||||
int32 number = 6;
|
||||
string name = 7;

||||
}

# GoDotEnv [](https://travis-ci.org/joho/godotenv) [](https://ci.appveyor.com/project/joho/godotenv)
|
||||
|
||||
A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
|
||||
|
||||
From the original Library:
|
||||
|
||||
> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
|
||||
>
|
||||
> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
|
||||
|
||||
It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
|
||||
|
||||
There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
|
||||
|
||||
## Installation
|
||||
|
||||
As a library
|
||||
|
||||
```shell
|
||||
go get github.com/joho/godotenv
|
||||
```
|
||||
|
||||
or if you want to use it as a bin command
|
||||
```shell
|
||||
go get github.com/joho/godotenv/cmd/godotenv
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Add your application configuration to your `.env` file in the root of your project:
|
||||
|
||||
```shell
|
||||
S3_BUCKET=YOURS3BUCKET
|
||||
SECRET_KEY=YOURSECRETKEYGOESHERE
|
||||
```
|
||||
|
||||
Then in your Go app you can do something like
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/joho/godotenv"
|
||||
"log"
|
||||
"os"
|
||||
)
|
||||
|
||||
func main() {
|
||||
err := godotenv.Load()
|
||||
if err != nil {
|
||||
log.Fatal("Error loading .env file")
|
||||
}
|
||||
|
||||
s3Bucket := os.Getenv("S3_BUCKET")
|
||||
secretKey := os.Getenv("SECRET_KEY")
|
||||
|
||||
// now do something with s3 or whatever
|
||||
}
|
||||
```
|
||||
|
||||
If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
|
||||
|
||||
```go
|
||||
import _ "github.com/joho/godotenv/autoload"
|
||||
```
|
||||
|
||||
While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
|
||||
|
||||
```go
|
||||
_ = godotenv.Load("somerandomfile")
|
||||
_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
|
||||
```
|
||||
|
||||
If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
|
||||
|
||||
```shell
|
||||
# I am a comment and that is OK
|
||||
SOME_VAR=someval
|
||||
FOO=BAR # comments at line end are OK too
|
||||
export BAR=BAZ
|
||||
```
|
||||
|
||||
Or finally you can do YAML(ish) style
|
||||
|
||||
```yaml
|
||||
FOO: bar
|
||||
BAR: baz
|
||||
```
|
||||
|
||||
as a final aside, if you don't want godotenv munging your env you can just get a map back instead
|
||||
|
||||
```go
|
||||
var myEnv map[string]string
|
||||
myEnv, err := godotenv.Read()
|
||||
|
||||
s3Bucket := myEnv["S3_BUCKET"]
|
||||
```
|
||||
|
||||
### Command Mode
|
||||
|
||||
Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
|
||||
|
||||
```
|
||||
godotenv -f /some/path/to/.env some_command with some args
|
||||
```
|
||||
|
||||
If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
|
||||
|
||||
## Contributing
|
||||
|
||||
Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
|
||||
|
||||
*code changes without tests will not be accepted*
|
||||
|
||||
1. Fork it
|
||||
2. Create your feature branch (`git checkout -b my-new-feature`)
|
||||
3. Commit your changes (`git commit -am 'Added some feature'`)
|
||||
4. Push to the branch (`git push origin my-new-feature`)
|
||||
5. Create new Pull Request
|
||||
|
||||
## Releases
|
||||
|
||||
Releases should follow [Semver](http://semver.org/) though the first couple of releases are `v1` and `v1.1`.
|
||||
|
||||
Use [annotated tags for all releases](https://github.com/joho/godotenv/issues/30). Example `git tag -a v1.2.1`
|
||||
|
||||
## CI
|
||||
|
||||
Linux: [](https://travis-ci.org/joho/godotenv) Windows: [](https://ci.appveyor.com/project/joho/godotenv)
|
||||
|
||||
## Who?
|
||||
|
||||
The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](http://whoisjohnbarton.com) based off the tests/fixtures in the original library.

// Package godotenv is a go port of the ruby dotenv library (https://github.com/bkeepers/dotenv)

// Examples/readme can be found on the github page at https://github.com/joho/godotenv

//
|

// SOME_ENV_VAR=somevalue
|

//
|
||||
// and then in your go code you can call
|
||||
//
|
||||
// godotenv.Load()
|
||||
//
|
||||
// and all the env vars declared in .env will be avaiable through os.Getenv("SOME_ENV_VAR")

githubql
|
||||
========
|
||||
|
||||
[](https://travis-ci.org/shurcooL/githubql) [](https://godoc.org/github.com/shurcooL/githubql)
|
||||
|
||||
Package `githubql` is a client library for accessing GitHub GraphQL API v4 (https://developer.github.com/v4/).
|
||||
|
||||
If you're looking for a client library for GitHub REST API v3, the recommended package is [`github.com/google/go-github/github`](https://godoc.org/github.com/google/go-github/github).
|
||||
|
||||
**Status:** In active early research and development. The API will change when opportunities for improvement are discovered; it is not yet frozen.
|
||||
|
||||
Focus
|
||||
-----
|
||||
|
||||
- Friendly, simple and powerful API.
|
||||
- Correctness, high performance and efficiency.
|
||||
- Support all of GitHub GraphQL API v4 via code generation from schema.
|
||||
|
||||
### Roadmap
|
||||
|
||||
Currently implemented:
|
||||
|
||||
- [x] Basic and intermediate queries.
|
||||
- [x] All mutations.
|
||||
- [x] Query minification before network transfer.
|
||||
- [x] Scalars.
|
||||
- [ ] Improved support (https://github.com/shurcooL/githubql/issues/9).
|
||||
- [x] Specifying arguments and passing variables.
|
||||
- [x] Thorough test coverage.
|
||||
- [x] Initial basic tests (hacky but functional).
|
||||
- [x] Better organized, medium sized tests.
|
||||
- [x] Aliases.
|
||||
- [ ] Documentation.
|
||||
- [x] Improved support.
|
||||
- [x] [Inline fragments](http://graphql.org/learn/queries/#inline-fragments).
|
||||
- [x] Generate all of objects, enums, input objects, etc.
|
||||
- [x] Clean up GitHub documentation to pass `golint`.
|
||||
- [x] Unions.
|
||||
- [x] Functional.
|
||||
- [x] Improved support (https://github.com/shurcooL/githubql/issues/10).
|
||||
- [ ] Directives (haven't tested yet, but expect it to be supported).
|
||||
- [ ] Research and complete, document the rest of GraphQL features.
|
||||
- [ ] Fully document (and add tests for edge cases) the `graphql` struct field tag.
|
||||
- [ ] Extremely clean, beautiful, idiomatic Go code (100% coverage, 0 lines of hacky code).
|
||||
- [x] Document all public identifiers.
|
||||
- [ ] Clean up implementations of some private helpers (currently functional, but hacky).
|
||||
|
||||
Future:
|
||||
|
||||
- [ ] GitHub Enterprise support (when it's available; GitHub themselves haven't released support yet, see [here](https://platform.github.community/t/is-graphql-available-for-github-enterprise/1224)).
|
||||
- [ ] Frontend support (e.g., using `githubql` in frontend Go code via [GopherJS](https://github.com/gopherjs/gopherjs)).
|
||||
- [ ] Local error detection (maybe).
|
||||
- [ ] Calculating a rate limit score before running the call.
|
||||
- [ ] Avoiding making network calls when rate limit quota exceeded and not yet reset.
|
||||
- [ ] Support for OpenTracing.
|
||||
|
||||
Known unknowns:
|
||||
|
||||
- Whether or not the current API design will scale to support all of advanced GraphQL specification features, and future changes. So far, things are looking great, no major blockers found. I am constantly evaluating it against alternative API designs that I've considered and prototyped myself, and new ones that I become aware of.
|
||||
- I have only explored roughly 80% of the GraphQL specification (Working Draft – October 2016).
|
||||
- Performance, allocations, memory usage under heavy workloads in long-running processes.
|
||||
- Optimal long-term package/code layout (i.e., whether to split off some of the parts into smaller sub-packages).
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
`githubql` requires Go version 1.8 or later.
|
||||
|
||||
```bash
|
||||
go get -u github.com/shurcooL/githubql
|
||||
```
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
### Authentication
|
||||
|
||||
GitHub GraphQL API v4 [requires authentication](https://developer.github.com/v4/guides/forming-calls/#authenticating-with-graphql). The `githubql` package does not directly handle authentication. Instead, when creating a new client, you're expected to pass an `http.Client` that performs authentication. The easiest and recommended way to do this is to use the [`golang.org/x/oauth2`](https://golang.org/x/oauth2) package. You'll need an OAuth token from GitHub (for example, a [personal API token](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/)) with the right scopes. Then:
|
||||
|
||||
```Go
|
||||
import "golang.org/x/oauth2"
|
||||
|
||||
func main() {
|
||||
src := oauth2.StaticTokenSource(
|
||||
&oauth2.Token{AccessToken: os.Getenv("GITHUB_TOKEN")},
|
||||
)
|
||||
httpClient := oauth2.NewClient(context.Background(), src)
|
||||
|
||||
client := githubql.NewClient(httpClient)
|
||||
// Use client...
|
||||
```
|
||||
|
||||
### Simple Query
|
||||
|
||||
To make a query, you need to define a Go type that corresponds to the GitHub GraphQL schema, and contains the fields you're interested in querying. You can look up the GitHub GraphQL schema at https://developer.github.com/v4/reference/query/.
|
||||
|
||||
For example, to make the following GraphQL query:
|
||||
|
||||
```GraphQL
|
||||
query {
|
||||
viewer {
|
||||
login
|
||||
createdAt
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can define this variable:
|
||||
|
||||
```Go
|
||||
var query struct {
|
||||
Viewer struct {
|
||||
Login githubql.String
|
||||
CreatedAt githubql.DateTime
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
And call `client.Query`, passing a pointer to it:
|
||||
|
||||
```Go
|
||||
err := client.Query(context.Background(), &query, nil)
|
||||
if err != nil {
|
||||
// Handle error.
|
||||
}
|
||||
fmt.Println(" Login:", query.Viewer.Login)
|
||||
fmt.Println("CreatedAt:", query.Viewer.CreatedAt)
|
||||
|
||||
// Output:
|
||||
// Login: gopher
|
||||
// CreatedAt: 2017-05-26 21:17:14 +0000 UTC
|
||||
```
|
||||
|
||||
### Arguments and Variables
|
||||
|
||||
Often, you'll want to specify arguments on some fields. You can use the `graphql` struct field tag for this.
|
||||
|
||||
For example, to make the following GraphQL query:
|
||||
|
||||
```GraphQL
|
||||
{
|
||||
repository(owner: "octocat", name: "Hello-World") {
|
||||
description
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can define this variable:
|
||||
|
||||
```Go
|
||||
var q struct {
|
||||
Repository struct {
|
||||
Description githubql.String
|
||||
} `graphql:"repository(owner: \"octocat\", name: \"Hello-World\")"`
|
||||
}
|
||||
```
|
||||
|
||||
And call `client.Query`:
|
||||
|
||||
```Go
|
||||
err := client.Query(context.Background(), &q, nil)
|
||||
if err != nil {
|
||||
// Handle error.
|
||||
}
|
||||
fmt.Println(q.Repository.Description)
|
||||
|
||||
// Output:
|
||||
// My first repository on GitHub!
|
||||
```
|
||||
|
||||
However, that'll only work if the arguments are constant and known in advance. Otherwise, you will need to make use of variables. Replace the constants in the struct field tag with variable names:
|
||||
|
||||
```Go
|
||||
// fetchRepoDescription fetches description of repo with owner and name.
|
||||
func fetchRepoDescription(ctx context.Context, owner, name string) (string, error) {
|
||||
var q struct {
|
||||
Repository struct {
|
||||
Description githubql.String
|
||||
} `graphql:"repository(owner: $owner, name: $name)"`
|
||||
}
|
||||
```
|
||||
|
||||
Then, define a `variables` map with their values:
|
||||
|
||||
```Go
|
||||
variables := map[string]interface{}{
|
||||
"owner": githubql.String(owner),
|
||||
"name": githubql.String(name),
|
||||
}
|
||||
```
|
||||
|
||||
Finally, call `client.Query` providing `variables`:
|
||||
|
||||
```Go
|
||||
err := client.Query(ctx, &q, variables)
|
||||
return string(q.Repository.Description), err
|
||||
}
|
||||
```
|
||||
|
||||
### Pagination
|
||||
|
||||
Imagine you wanted to get a complete list of comments in an issue, and not just the first 10 or so. To do that, you'll need to perform multiple queries and use pagination information. For example:
|
||||
|
||||
```Go
|
||||
type comment struct {
|
||||
Body githubql.String
|
||||
Author struct {
|
||||
Login githubql.String
|
||||
AvatarURL githubql.URI `graphql:"avatarUrl(size: 72)"`
|
||||
}
|
||||
ViewerCanReact githubql.Boolean
|
||||
}
|
||||
var q struct {
|
||||
Repository struct {
|
||||
Issue struct {
|
||||
Comments struct {
|
||||
Nodes []comment
|
||||
PageInfo struct {
|
||||
EndCursor githubql.String
|
||||
HasNextPage githubql.Boolean
|
||||
}
|
||||
} `graphql:"comments(first: 100, after: $commentsCursor)"` // 100 per page.
|
||||
} `graphql:"issue(number: $issueNumber)"`
|
||||
} `graphql:"repository(owner: $repositoryOwner, name: $repositoryName)"`
|
||||
}
|
||||
variables := map[string]interface{}{
|
||||
"repositoryOwner": githubql.String(owner),
|
||||
"repositoryName": githubql.String(name),
|
||||
"issueNumber": githubql.Int(issue),
|
||||
"commentsCursor": (*githubql.String)(nil), // Null after argument to get first page.
|
||||
}
|
||||
|
||||
// Get comments from all pages.
|
||||
var allComments []comment
|
||||
for {
|
||||
err := s.clQL.Query(ctx, &q, variables)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
allComments = append(allComments, q.Repository.Issue.Comments.Nodes...)
|
||||
if !q.Repository.Issue.Comments.PageInfo.HasNextPage {
|
||||
break
|
||||
}
|
||||
variables["commentsCursor"] = githubql.NewString(q.Repository.Issue.Comments.PageInfo.EndCursor)
|
||||
}
|
||||
```
|
||||
|
||||
There is more than one way to perform pagination. Consider additional fields inside [`PageInfo`](https://developer.github.com/v4/reference/object/pageinfo/) object.
|
||||
|
||||
### Mutations
|
||||
|
||||
Mutations often require information that you can only find out by performing a query first. Let's suppose you've already done that.
|
||||
|
||||
For example, to make the following GraphQL mutation:
|
||||
|
||||
```GraphQL
|
||||
mutation($input: AddReactionInput!) {

|
||||
Content: githubql.Hooray,
|
||||
}
|
||||
```
|
||||
|
||||
And call `client.Mutate`:
|
||||
|
||||
```Go
|
||||
err := client.Mutate(context.Background(), &m, input, nil)
|
||||
if err != nil {
|
||||
// Handle error.
|

}
|

fmt.Printf("Added a %v reaction to subject with ID %#v!\n", m.AddReaction.Reaction.Content, m.AddReaction.Subject.ID)
|
||||
|

// Output:
|
||||
// Added a HOORAY reaction to subject with ID "MDU6SXNzdWUyMTc5NTQ0OTc="!

graphql
|
||||
=======
|
||||
|
||||
[](https://travis-ci.org/shurcooL/graphql) [](https://godoc.org/github.com/shurcooL/graphql)
|
||||
|
||||
Package `graphql` provides a GraphQL client implementation.
|
||||
|
||||
For more information, see package [`github.com/shurcooL/githubql`](https://github.com/shurcooL/githubql), which is a specialized version targeting GitHub GraphQL API v4. That package is driving the feature development.
|
||||
|
||||
**Status:** In active early research and development. The API will change when opportunities for improvement are discovered; it is not yet frozen.
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
`graphql` requires Go version 1.8 or later.
|
||||
|
||||
```bash
|
||||
go get -u github.com/shurcooL/graphql
|
||||
```
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Construct a GraphQL client, specifying the GraphQL server URL. Then, you can use it to make GraphQL queries and mutations.
|
||||
|
||||
```Go
|
||||
client := graphql.NewClient("https://example.com/graphql", nil, nil)
|
||||
// Use client...
|
||||
```
|
||||
|
||||
### Authentication
|
||||
|
||||
Some GraphQL servers may require authentication. The `graphql` package does not directly handle authentication. Instead, when creating a new client, you're expected to pass an `http.Client` that performs authentication. The easiest and recommended way to do this is to use the [`golang.org/x/oauth2`](https://golang.org/x/oauth2) package. You'll need an OAuth token with the right scopes. Then:
|
||||
|
||||
```Go
|
||||
import "golang.org/x/oauth2"
|
||||
|
||||
func main() {
|
||||
src := oauth2.StaticTokenSource(
|
||||
&oauth2.Token{AccessToken: os.Getenv("GRAPHQL_TOKEN")},
|
||||
)
|
||||
httpClient := oauth2.NewClient(context.Background(), src)
|
||||
|
||||
client := graphql.NewClient("https://example.com/graphql", httpClient, nil)
|
||||
// Use client...
|
||||
```
|
||||
|
||||
### Simple Query
|
||||
|
||||
To make a GraphQL query, you need to define a corresponding Go type.
|
||||
|
||||
For example, to make the following GraphQL query:
|
||||
|
||||
```GraphQL
|
||||
query {
|
||||
me {
|
||||
name
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can define this variable:
|
||||
|
||||
```Go
|
||||
var query struct {
|
||||
Me struct {
|
||||
Name graphql.String
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
And call `client.Query`, passing a pointer to it:
|
||||
|
||||
```Go
|
||||
err := client.Query(context.Background(), &query, nil)
|
||||
if err != nil {
|
||||
// Handle error.
|
||||
}
|
||||
fmt.Println(query.Me.Name)
|
||||
|
||||
// Output: Luke Skywalker
|
||||
```
|
||||
|
||||
### Arguments and Variables
|
||||
|
||||
Often, you'll want to specify arguments on some fields. You can use the `graphql` struct field tag for this.
|
||||
|
||||
For example, to make the following GraphQL query:
|
||||
|
||||
```GraphQL
|
||||
{
|
||||
human(id: "1000") {
|
||||
name
|
||||
height(unit: METER)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can define this variable:
|
||||
|
||||
```Go
|
||||
var q struct {
|
||||
Human struct {
|
||||
Name graphql.String
|
||||
Height graphql.Float `graphql:"height(unit: METER)"`
|
||||
} `graphql:"human(id: \"1000\")"`
|
||||
}
|
||||
```
|
||||
|
||||
And call `client.Query`:
|
||||
|
||||
```Go
|
||||
err := client.Query(context.Background(), &q, nil)
|
||||
if err != nil {
|
||||
// Handle error.
|
||||
}
|
||||
fmt.Println(q.Human.Name)
|
||||
fmt.Println(q.Human.Height)
|
||||
|
||||
// Output:
|
||||
// Luke Skywalker
|
||||
// 1.72
|
||||
```
|
||||
|
||||
However, that'll only work if the arguments are constant and known in advance. Otherwise, you will need to make use of variables. Replace the constants in the struct field tag with variable names:
|
||||
|
||||
```Go
|
||||
var q struct {
|
||||
Human struct {
|
||||
Name graphql.String
|
||||
Height graphql.Float `graphql:"height(unit: $unit)"`
|
||||
} `graphql:"human(id: $id)"`
|
||||
}
|
||||
```
|
||||
|
||||
Then, define a `variables` map with their values:
|
||||
|
||||
```Go
|
||||
variables := map[string]interface{}{
|
||||
"id": graphql.ID(id),
|
||||
"unit": starwars.LengthUnit("METER"),
|
||||
}
|
||||
```
|
||||
|
||||
Finally, call `client.Query` providing `variables`:
|
||||
|
||||
```Go
|
||||
err := client.Query(context.Background(), &q, variables)
|
||||
if err != nil {
|
||||
// Handle error.
|
||||
}
|
||||
```
|
||||
|
||||
### Mutations
|
||||
|
||||
Mutations often require information that you can only find out by performing a query first. Let's suppose you've already done that.
|
||||
|
||||
For example, to make the following GraphQL mutation:
|
||||
|
||||
```GraphQL
|
||||
mutation($ep: Episode!, $review: ReviewInput!) {
|
||||
createReview(episode: $ep, review: $review) {
|
||||
stars
|
||||
commentary
|
||||
}
|
||||
}
|
||||
variables {
|
||||
"ep": "JEDI",
|
||||
"review": {
|
||||
"stars": 5,
|
||||
"commentary": "This is a great movie!"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can define:
|
||||
|
||||
```Go
|
||||
var m struct {
|
||||
CreateReview struct {
|
||||
Stars graphql.Int
|
||||
Commentary graphql.String
|
||||
} `graphql:"createReview(episode: $ep, review: $review)"`
|
||||
}
|
||||
variables := map[string]interface{}{
|
||||
"ep": starwars.Episode("JEDI"),
|
||||
"review": starwars.ReviewInput{
|
||||
Stars: graphql.Int(5),
|
||||
Commentary: graphql.String("This is a great movie!"),
|
||||
},
|
||||
}
|
||||
```

# Contributing to Go
|
||||
|
||||
Go is an open source project.
|
||||
|
||||
It is the work of hundreds of contributors. We appreciate your help!
|
||||
|
||||
|
||||
## Filing issues
|
||||
|
||||
When [filing an issue](https://github.com/golang/oauth2/issues), make sure to answer these five questions:
|
||||
|
||||
1. What version of Go are you using (`go version`)?
|
||||
2. What operating system and processor architecture are you using?
|
||||
3. What did you do?
|
||||
4. What did you expect to see?
|
||||
5. What did you see instead?
|
||||

# OAuth2 for Go
|
||||

[](https://travis-ci.org/golang/oauth2)
|
||||
[](https://godoc.org/golang.org/x/oauth2)
|
||||
|
||||
oauth2 package contains a client implementation for OAuth 2.0 spec.
|
||||
|
||||
## Installation

||||
|
||||
~~~~
|
||||
go get golang.org/x/oauth2
|
||||

|
||||
|
||||

## App Engine
|
||||
|
||||
In change 96e89be (March 2015) we removed the `oauth2.Context2` type in favor
|
||||
of the [`context.Context`](https://golang.org/x/net/context#Context) type from
|
||||
the `golang.org/x/net/context` package
|
||||
|
||||
This means its no longer possible to use the "Classic App Engine"
|
||||
`appengine.Context` type with the `oauth2` package. (You're using
|
||||
Classic App Engine if you import the package `"appengine"`.)
|
||||
|
||||
To work around this, you may use the new `"google.golang.org/appengine"`
|
||||
package. This package has almost the same API as the `"appengine"` package,
|
||||
but it can be fetched with `go get` and used on "Managed VMs" and well as
|
||||
Classic App Engine.
|
||||
|
||||
See the [new `appengine` package's readme](https://github.com/golang/appengine#updating-a-go-app-engine-app)
|
||||
for information on updating your app.
|
||||
|
||||
If you don't want to update your entire app to use the new App Engine packages,
|
||||
you may use both sets of packages in parallel, using only the new packages
|
||||
with the `oauth2` package.
|
||||
|
||||
import (
|
||||
"golang.org/x/net/context"
|
||||
"golang.org/x/oauth2"

|
||||
var c appengine.Context = appengine.NewContext(r)
|
||||
c.Infof("Logging a message with the old package")
|
||||
|
||||
var ctx context.Context = newappengine.NewContext(r)
|
||||
client := &http.Client{
|
||||
Transport: &oauth2.Transport{
|
||||
Source: google.AppEngineTokenSource(ctx, "scope"),
