underscore-go

A Go port of Underscore.js

setup

install Go with gvm

git clone [email protected]:moovweb/gvm.git
cd gvm/
vi binscripts/gvm-installer 
./binscripts/gvm-installer 
source $HOME/.gvm/scripts/gvm

Install go

gvm listall
gvm install go1.2.1
gvm use go1.2.1

Testing

git clone [email protected]/markmontymark/asserts.git
cd asserts/
go install
git clone [email protected]/markmontymark/underscore-go.git
cd underscore-go/
go test

Benchmarking

cd underscore-go/
go test -bench=.

• so far, only a few Array functions are benchmarked, but it's already interesting to see what's fast and what's slow

TODO

• Port speed.js to speed_test.go
• Add Bench*() functions for benchmarking
• Add Example*() functions for showing how to use this code
• Export an Underscore Interface interface, to allow different types to provide enumeration, possibly something like C#'s IEnumerable?

Example usage

• adapted from arrays_test.go

   package main
  
   import "fmt"
   import "underscore"
  
   func main () {
   	num := 35
   	numbers2 := []underscore.T{10, 20, 30, 40, 50}
   	if v := underscore.IndexOf(numbers2, num, func (a underscore.T, b underscore.T) bool { return a.(int) < b.(int)}, true); v == -1 {
   		fmt.Println("35 is not in the list")
   	}
   }
  

  • Copy the above code in a file, runme.go, and then on the command line, go run runme.go
