jsoncolor
=========
[](https://godoc.org/github.com/nwidger/jsoncolor)
`jsoncolor` is a drop-in replacement for `encoding/json`'s `Marshal`
and `MarshalIndent` functions which produce colorized output using
fatih's [color](https://github.com/fatih/color) package.
## Installation
```
go get -u github.com/nwidger/jsoncolor
```
## Usage
To use as a replacement for `encoding/json`, exchange
`import "encoding/json"` with `import json "github.com/nwidger/jsoncolor"`.
`json.Marshal` and `json.MarshalIndent` will now produce colorized
output.
## Custom Colors
The colors used for each type of token can be customized by creating a
custom `Formatter` and changing its `XXXColor` fields. See
[color.New](https://godoc.org/github.com/fatih/color#New) for creating
custom color values and the
[GoDocs](https://godoc.org/github.com/nwidger/jsoncolor#pkg-variables)
for the default colors.
``` go
import (
"bytes"
"encoding/json"
"fmt"
"log"
"github.com/fatih/color"
"github.com/nwidger/jsoncolor"
)
// marshal v into src using encoding/json
src, err := json.Marshal(v)
if err != nil {
log.Fatal(err)
}
// create custom formatter,
f := jsoncolor.NewFormatter()
// set custom colors
f.SpaceColor = color.New(color.FgRed, color.Bold)
f.CommaColor = color.New(color.FgWhite, color.Bold)
f.ColonColor = color.New(color.FgBlue)
f.ObjectColor = color.New(color.FgBlue, color.Bold)
f.ArrayColor = color.New(color.FgWhite)
f.FieldColor = color.New(color.FgGreen)
f.StringColor = color.New(color.FgBlack, color.Bold)
f.TrueColor = color.New(color.FgWhite, color.Bold)
f.FalseColor = color.New(color.FgRed)
f.NumberColor = color.New(color.FgWhite)
f.NullColor = color.New(color.FgWhite, color.Bold)
// colorized output is written to dst
dst := &bytes.Buffer{}
err := f.Format(dst, src)
if err != nil {
log.Fatal(err)
}
// print colorized output to stdout
fmt.Println(dst.String())
```
