Pure Go implementation of jq

This is an implementation of jq command written in Go language. You can also embed gojq as a library to your Go products.

Usage

 $ echo '{"foo": 128}' | gojq '.foo'
128
 $ echo '{"a": {"b": 42}}' | gojq '.a.b'
42
 $ echo '{"id": "sample", "10": {"b": 42}}' | gojq '{(.id): .["10"].b}'
{
  "sample": 42
}
 $ echo '[{"id":1},{"id":2},{"id":3}]' | gojq '.[] | .id'
1
2
3
 $ echo '{"a":1,"b":2}' | gojq '.a += 1 | .b *= 2'
{
  "a": 2,
  "b": 4
}
 $ echo '{"a":1} [2] 3' | gojq '. as {$a} ?// [$a] ?// $a | $a'
1
2
3
 $ echo '{"foo": 4722366482869645213696}' | gojq .foo
4722366482869645213696  # keeps the precision of number while jq does not
 $ gojq -n 'def fact($n): if $n < 1 then 1 else $n * fact($n - 1) end; fact(50)'
30414093201713378043612608166064768844377641568960512000000000000 # arbitrary-precision integer calculation

Nice error messages.

 $ echo '[1,2,3]' | gojq  '.foo & .bar'
gojq: invalid query: .foo & .bar
    .foo & .bar
         ^  unexpected token "&"
 $ echo '{"foo": { bar: [] } }' | gojq '.'
gojq: invalid json: <stdin>
    {"foo": { bar: [] } }
              ^  invalid character 'b' looking for beginning of object key string

Installation

Homebrew
brew install gojq
Build from source
go get github.com/itchyny/gojq/cmd/gojq
Docker
docker run -i --rm itchyny/gojq

Difference to jq

  • gojq is purely implemented with Go language and is completely portable. jq depends on the C standard library so the availability of math functions depends on the library. jq also depends on the regular expression library and it makes build scripts complex.
  • gojq implements nice error messages for invalid query and JSON input. The error message of jq is sometimes difficult to tell where to fix the query.
  • gojq does not keep the order of object keys. I understand this might cause problems for some scripts but basically we should not rely on the order of object keys. I would implement when ordered map is implemented in the standard library of Go but I'm less motivated.
  • gojq supports arbitrary-precision integer calculation while jq does not. This is important to keeping the precision of numeric IDs or nanosecond values. You can use gojq to solve some mathematical problems which require big integers.
  • gojq supports reading from YAML input while jq does not. gojq also supports YAML output.

Usage as a library

You can use the gojq parser and interpreter from your Go products.

package main

import (
	"fmt"
	"log"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse(".foo | ..")
	if err != nil {
		log.Fatalln(err)
	}
	input := map[string]interface{}{"foo": []interface{}{1, 2, 3}}
	iter := query.Run(input) // or query.RunWithContext
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}
}
  • Firstly, use gojq.Parse(string) (*Query, error) to get the query from a string.
  • Secondly, get the result iterator
    • using query.Run or query.RunWithContext
    • or alternatively, compile the query using gojq.Compile and then code.Run or code.RunWithContext. You can reuse the *Code against multiple inputs to avoid compiling the same query.
    • In either case, the query input should have type []interface{} for an array and map[string]interface{} for a map (just like decoded to an interface{} using the encoding/json package). You can't use []int or map[string]string, for example.
  • Thirdly, iterate through the results using iter.Next() (interface{}, bool). The iterater can emit an error so make sure to handle it. Termination is notified by the second returned value of Next(). The reason why the return type is not (interface{}, error) is that the iterator can emit multiple errors and you can continue after an error.

gojq.Compile allows to configure the following compiler options.

  • gojq.WithModuleLoader allows to load modules. By default, the module feature is disabled. If you want to load modules from the filesystem, use gojq.NewModuleLoader.
  • gojq.WithEnvironLoader allows to configure the environment variables referenced by env and $ENV. By default, OS environment variables are not accessible due to security reason. You can use gojq.WithEnvironLoader(os.Environ) if you want.
  • gojq.WithVariables allows to configure the variables which can be used in the query. Pass the values of the variables to code.Run in the same order.
  • gojq.WithFunction allows to add a custom internal function.
  • gojq.WithInputIter allows to use input and inputs functions. By default, these functions are disabled.

Functions

func Marshal added in v0.12.0 

func Marshal(v interface{}) ([]byte, error)

Marshal returns the jq-flavored JSON encoding of v.

This method only accepts limited types (nil, bool, int, float64, *big.Int, string, []interface{} and map[string]interface{}) because these are the possible types a gojq iterator can emit. This method marshals NaN to null, truncates infinities to (+|-) math.MaxFloat64 and does not escape '<' and '>' for embedding in HTML. These behaviors are based on the marshaler of jq command and different from the standard library method json.Marshal.

Types

type Array 

type Array struct {
	Query *Query
}

Array ...

func (*Array) String added in v0.4.0 

func (e *Array) String() string

type Code struct {
	// contains filtered or unexported fields
}

	"log"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse(".[] | .foo")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(query)
	if err != nil {
		log.Fatalln(err)
	}
	iter := code.Run([]interface{}{
		nil,
		"string",
		42,
		[]interface{}{"foo"},
		map[string]interface{}{"foo": 42},
	})
	for {

			continue
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

<nil>
expected an object but got: string ("string")
expected an object but got: number (42)
expected an object but got: array (["foo"])
42

func (*Code) Run added in v0.8.0 

func (c *Code) Run(v interface{}, values ...interface{}) Iter

Run runs the code with the variable values (which should be in the same order as the given variables using WithVariables) and returns a result iterator.

It is safe to call this method of a *Code in multiple goroutines.

Example 
package main

import (
	"fmt"
	"log"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse(".foo")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(query)
	if err != nil {
		log.Fatalln(err)
	}
	input := map[string]interface{}{"foo": 42}
	iter := code.Run(input)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

42

func (*Code) RunWithContext added in v0.8.0 

func (c *Code) RunWithContext(ctx context.Context, v interface{}, values ...interface{}) Iter

RunWithContext runs the code with context.

Example 
package main

import (
	"context"
	"fmt"
	"log"
	"time"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse("def f: f; f, f")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(query)
	if err != nil {
		log.Fatalln(err)
	}
	ctx, cancel := context.WithTimeout(context.Background(), 100*time.Millisecond)
	defer cancel()
	iter := code.RunWithContext(ctx, nil)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			fmt.Println(err)
			continue
		}
		_ = v
	}

}

Output:

context deadline exceeded

type CompilerOption added in v0.8.0 

type CompilerOption func(*compiler)

CompilerOption is a compiler option.

func WithEnvironLoader added in v0.9.0 

func WithEnvironLoader(environLoader func() []string) CompilerOption

WithEnvironLoader is a compiler option for environment variables loader. The OS environment variables are not accessible by default due to security reason. You can pass os.Environ if you allow to access it.

Example 
package main

import (
	"fmt"
	"log"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse("env | keys[]")
	if err != nil {

	}
	code, err := gojq.Compile(
		query,
		gojq.WithEnvironLoader(func() []string {
			return []string{"foo=42", "bar=128"}
		}),
	)
	if err != nil {
		log.Fatalln(err)
	}
	iter := code.Run(nil)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

"bar"
"foo"

func WithFunction added in v0.12.0 

func WithFunction(name string, minarity int, maxarity int,
	f func(interface{}, []interface{}) interface{}) CompilerOption

WithFunction is a compiler option for adding a custom internal function. Specify the minimum and maximum count of the function arguments. These values should satisfy 0 <= minarity <= maxarity <= 30, otherwise panics. On handling numbers, you should take account to int, float64 and *big.Int.

Example 
package main

import (
	"encoding/json"
	"fmt"
	"log"
	"math/big"
	"strconv"

	"github.com/itchyny/gojq"
)

func toFloat(x interface{}) (float64, bool) {
	switch x := x.(type) {
	case int:
		return float64(x), true
	case float64:
		return x, true
	case *big.Int:
		f, err := strconv.ParseFloat(x.String(), 64)
		return f, err == nil
	default:
		return 0.0, false
	}
}

func main() {
	query, err := gojq.Parse(".[] | f | f(3)")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(
		query,
		gojq.WithFunction("f", 0, 1, func(x interface{}, xs []interface{}) interface{} {
			if x, ok := toFloat(x); ok {
				if len(xs) == 1 {
					if y, ok := toFloat(xs[0]); ok {
						x *= y
					} else {
						return fmt.Errorf("f cannot be applied to: %v, %v", x, xs)
					}
				} else {
					x += 2
				}
				return x
			}
			return fmt.Errorf("f cannot be applied to: %v, %v", x, xs)
		}),
	)
	if err != nil {
		log.Fatalln(err)
	}
	input := []interface{}{0, 1, 2.5, json.Number("10000000000000000000000000000000000000000")}
	iter := code.Run(input)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

func WithInputIter added in v0.10.0 

func WithInputIter(inputIter Iter) CompilerOption

WithInputIter is a compiler option for input iterator used by input(s)/0. Note that input and inputs functions are not allowed by default. We have to distinguish the query input and the values for input(s) functions. For example, consider using inputs with --null-input. If you want to allow input(s) functions, create an Iter and use WithInputIter option.

Example 
package main

import (
	"encoding/json"
	"fmt"
	"io"
	"log"
	"strings"

	"github.com/itchyny/gojq"
)

type testInputIter struct {
	dec *json.Decoder
}

func newTestInputIter(r io.Reader) *testInputIter {
	dec := json.NewDecoder(r)
	dec.UseNumber()
	return &testInputIter{dec: dec}
}

func (i *testInputIter) Next() (interface{}, bool) {
	var v interface{}
	if err := i.dec.Decode(&v); err != nil {
		if err == io.EOF {
			return nil, false
		}
		return err, true
	}
	return v, true
}

func main() {
	query, err := gojq.Parse("reduce inputs as $x (0; . + $x)")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(
		query,
		gojq.WithInputIter(
			newTestInputIter(strings.NewReader("1 2 3 4 5")),
		),
	)
	if err != nil {
		log.Fatalln(err)
	}
	iter := code.Run(nil)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

15

func WithModuleLoader added in v0.8.0 

func WithModuleLoader(moduleLoader ModuleLoader) CompilerOption

WithModuleLoader is a compiler option for module loader. If you want to load modules from the filesystem, use NewModuleLoader.

Example 
package main

import (
	"fmt"
	"log"

	"github.com/itchyny/gojq"
)

type moduleLoader struct{}

func (*moduleLoader) LoadModule(name string) (*gojq.Query, error) {
	switch name {
	case "module1":
		return gojq.Parse(`
			module { name: "module1", test: 42 };
			import "module2" as foo;
			def f: foo::f;
		`)
	case "module2":
		return gojq.Parse(`
			def f: .foo;
		`)
	}
	return nil, fmt.Errorf("module not found: %q", name)
}

func main() {
	query, err := gojq.Parse(`
		import "module1" as m;
		m::f
	`)
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(
		query,
		gojq.WithModuleLoader(&moduleLoader{}),
	)
	if err != nil {
		log.Fatalln(err)
	}
	input := map[string]interface{}{"foo": 42}
	iter := code.Run(input)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

Output:

42

func WithVariables added in v0.8.0 

func WithVariables(variables []string) CompilerOption

WithVariables is a compiler option for variable names. The variables can be used in the query. You have to give the values to query.Run or code.Run in the same order.

Example 
package main

import (
	"fmt"
	"log"

	"github.com/itchyny/gojq"
)

func main() {
	query, err := gojq.Parse("$x * 100 + $y, $z")
	if err != nil {
		log.Fatalln(err)
	}
	code, err := gojq.Compile(
		query,
		gojq.WithVariables([]string{
			"$x", "$y", "$z",
		}),
	)
	if err != nil {
		log.Fatalln(err)
	}
	iter := code.Run(nil, 12, 42, 128)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			log.Fatalln(err)
		}
		fmt.Printf("%#v\n", v)
	}

}

	if err != nil {
		log.Fatalln(err)
	}
	ctx, cancel := context.WithTimeout(context.Background(), 100*time.Millisecond)
	defer cancel()
	iter := query.RunWithContext(ctx, nil)
	for {
		v, ok := iter.Next()
		if !ok {
			break
		}
		if err, ok := v.(error); ok {
			fmt.Println(err)
			continue
