jflect

Overview ¶

Jflect takes JSON from stdin and outputs go structs to stdout.

Installing

go get github.com/str1ngs/jflect

Examples ¶

Web service:

curl https://api.github.com/users/str1ngs | jflect -s GithubUser

Output:

 type GitHubUser struct {
	 AvatarUrl   string `json:"avatar_url"`
	 Bio         string `json:"bio"`
	 CreatedAt   string `json:"created_at"`
	 Followers   int    `json:"followers"`
	 Following   int    `json:"following"`
	 GravatarId  string `json:"gravatar_id"`
	 Hireable    bool   `json:"hireable"`
	 HtmlUrl     string `json:"html_url"`
	 Id          int    `json:"id"`
	 Location    string `json:"location"`
	 Login       string `json:"login"`
	 Name        string `json:"name"`
	 PublicGists int    `json:"public_gists"`
	 PublicRepos int    `json:"public_repos"`
	 Type        string `json:"type"`
	 Url         string `json:"url"`
 }

From file:

jflect < foo.json

Saving is just a matter of redirecting stdout to a file.

jflect < foo.json > foo.go

curl https://api.github.com/users/str1ngs | jflect -s GihubUser > gituser.go

Notes ¶

Jflect is primarily designed to fast prototype go structs. Its not intended for automation. It does handle nested JSON objects. But does not currently handle arbitrary JSON arrays.
