# Go Enterprise

Common enterprise features for the Go programming language.

This is free and unencumbered software released into the

[public domain](http://creativecommons.org/publicdomain/zero/1.0).

[![Build Status](https://github.com/pascaldekloe/goe/actions/workflows/go.yml/badge.svg)](https://github.com/pascaldekloe/goe/actions/workflows/go.yml)

## Expression Language [![API](https://pkg.go.dev/badge/github.com/pascaldekloe/goe/el.svg)](https://pkg.go.dev/github.com/pascaldekloe/goe/el)

GoEL expressions provide error free access to Go types.

It serves as a lightweigth alternative to [unified EL](https://docs.oracle.com/javaee/5/tutorial/doc/bnahq.html), [SpEL](http://docs.spring.io/spring/docs/current/spring-framework-reference/html/expressions.html) or even [XPath](http://www.w3.org/TR/xpath), [CSS selectors](http://www.w3.org/TR/css3-selectors) and friends.

``` Go

func FancyOneLiners() {

	// Single field selection:

	upper, applicable := el.Bool(`/CharSet[0x1F]/isUpperCase`, x)

	// Escape path separator slash:

	warnings := el.Strings(`/Report/Stats["I\x2fO"]/warn[*]`, x)

	// Data modification:

	el.Assign(x, `/Nodes[7]/Cache/TTL`, 3600)

```

#### Performance

The implementation is optimized for performance. No need to precompile expressions.

```

## Metrics [![API](https://pkg.go.dev/badge/github.com/pascaldekloe/goe/metrics.svg)](https://pkg.go.dev/github.com/pascaldekloe/goe/metrics)

Yet another StatsD implementation.

``` Go

var Metrics = metrics.NewDummy()

func GetSomething(w http.ResponseWriter, r *http.Request) {

	Metrics.Seen("http.something.gets", 1)

	defer Metrics.Took("http.something.get", time.Now())

```

## Verification [![API](https://pkg.go.dev/badge/github.com/pascaldekloe/goe/verify.svg)](https://pkg.go.dev/github.com/pascaldekloe/goe/verify)

Test assertions on big objects can be cumbersome with ```reflect.DeepEqual``` and ```"Got %#v, want %#v"```.

Package `verify` offers convenience with reporting. For example `verify.Values(t, "character", got, want)` might print:

```

--- FAIL: TestValuesDemo (0.00s)

	demo_test.go:72: verification for character:

		/Novel[6]/Title: Got "Gold Finger", want "Goldfinger"

		                          ^

		/Film[20]/Year: Got 1953 (0x7a1), want 2006 (0x7d6)

```
