cor-lang - npm Package Versions

0.4.0

Interesting features has been added to Cor this time, the exception handling has been revamped with simplified syntax while it remains fully compatible with javascript exceptions model. The Cor syntax now supports the exist (?) operator, which is a good replacement for the if statement to check for existence, it makes Cor more expressive but still sober and readable.

Let's see an example of error handling in 0.4.0:

// throwing errors
func explode() { error('Booooom!') }

// handling error
func handleError() {
    catch horror() {
        console.log(error())
    }
}

• Syntax
  • Add Exist Operator ?, example: customers[0]?.accounts?.length
  • Change the old try/catch/finally for the catch/error statement
• Remove the package system in favor of well known modules
• Add social icons and links to Documentation

0.3.0

This release brings important language additions in order to look modern allowing to write less code without loosing readability. Was added the coalesce operator (??), also the & symbol now should be used as a replacement of @ to create new objects. Now the lambda function has a convenient shorter syntax to fill some use cases, however, the new syntax does not replaces the classic one.

A show case using some features of the new syntax. Lets assume we are using Underscore.js:

Before 0.3.0:

stooges = [
    @[name: 'curly', age: 25],
    @[name: 'moe',   age: 21],
    @[name: 'larry', age: 23],
]

func init() {
    ch = _.chain(stooges)
    ch.sortBy(func(s){ return s.age })
    ch.map(func(s){ return s.name + ' is ' + s.age })

    console.log(ch.first().value()) // "moe is 21"
}

With 0.3.0:

stooges = [
    &[name: 'curly', age: 25],
    &[name: 'moe',   age: 21],
    &[name: 'larry', age: 23],
]

func init() {
    ch = _.chain(stooges)
    ch.sortBy(func(s) s.age)
    ch.map(func(s) s.name + ' is ' + s.age)
    
    console.log(ch.first().value()) // "moe is 21"
}

As you can see, the code with 0.3.0 is cleaner and still remains readable with a modern look.

0.2.6

Important changes has been factored since 0.2.1, the most important new feature is the possibility to build your project in 4 different ways: domready, commonjs, amd and global.

• Loader
  • Refactor the way it evals js source
• Cli
  • Build command now produces a named function to improve debugging experience
  • Build command now supports for amd, commonjs and amd package types
  • Fixed a bug in bin/cor.cmd, it now gets arguments properly
• Compiler
  • Preserver comments and passthrough it as javscript comments
  • Improve source-map support for classes and string literals
