Go playground

Package validator implements value validations for structs and individual fields based on tags.

The Go Playground is a web service that runs on go. The service receives a Go program, vets , compiles, links, and runs the program inside a sandbox, then returns the output. If the program contains tests or examples and no main function, the service runs the tests. Benchmarks will likely not be supported since the program runs in a sandboxed environment with limited resources. The article " Inside the Go Playground " describes how the playground is implemented.

In September we introduced the Go Playground , a web service that compiles and executes arbitrary Go code and returns the program output. In this article we will take a look at how the playground is implemented and integrated with these services. The implementation involves a variant operating system environment and runtime and our description here assumes you have some familiarity with systems programming using Go. The interesting part is how we safely execute arbitrary user code in a secure environment while still providing core functionality such as time, the network, and the file system. The back end uses a special version of the gc tool chain that generates NaCl executables. This special tool chain was merged into Go 1. To learn more, read the design document. This presents a problem, however.

New validator. The playground service is used by more than just the official Go project Go by Example is one other instance and we are happy for you to use it on your own site. It has the following unique features: Cross Field and Cross Struct validations by using validation tags or custom validators. You signed in with another tab or window. This makes it easier to cache programs by giving them deterministic output. The only communication a playground program has to the outside world is by writing to standard output and standard error. Notifications Fork 1. Ability to dive into both map keys and values for validation Handles type interface by determining it's underlying type prior to validation. Feb 11, All we ask is that you contact us first note this is a public mailing list , that you use a unique user agent in your requests so we can identify you , and that your service is of benefit to the Go community.

Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.

This project has grown large enough that more than one person is required to properly support the community.
