# pux-starter-app
Starter [Pux](https://github.com/alexmingoia/purescript-pux/) application using
webpack with hot-reloading and time-travel debug using
[pux-devtool](https://github.com/alexmingoia/pux-devtool).
See the [Guide](https://alexmingoia.github.io/purescript-pux) for help learning
Pux.
![Pux starter app animation](support/pux-starter-app.gif)
## Installation
```sh
git clone git://github.com/alexmingoia/pux-starter-app.git example
cd example
npm install
npm start
```
Visit `http://localhost:3000` in your browser, edit `src/purs/Layout.purs`
and watch the magic!
## Available scripts
### watch
`npm start` or `npm run watch` will start a development server, which
hot-reloads your application when sources changes.
### serve
`npm run serve` serves your application without watching for changes or
hot-reloading.
### build
`npm run build` bundles and minifies your application to run in production mode.

/*
Syndication (feed) generator library for golang.
Installing
go get github.com/gorilla/feeds
Feeds provides a simple, generic Feed interface with a generic Item object as well as RSS and Atom specific RssFeed and AtomFeed objects which allow access to all of each spec's defined elements.
Examples
Create a Feed and some Items in that feed using the generic interfaces:
import (
"time"
. "github.com/gorilla/feeds
)
now = time.Now()
feed := &Feed{
Title: "jmoiron.net blog",
Link: &Link{Href: "http://jmoiron.net/blog"},
Description: "discussion about tech, footie, photos",
Author: &Author{Name: "Jason Moiron", Email: "jmoiron@jmoiron.net"},
Created: now,
Copyright: "This work is copyright © Benjamin Button",
}
feed.Items = []*Item{
&Item{
Title: "Limiting Concurrency in Go",
Link: &Link{Href: "http://jmoiron.net/blog/limiting-concurrency-in-go/"},
Description: "A discussion on controlled parallelism in golang",
Author: &Author{Name: "Jason Moiron", Email: "jmoiron@jmoiron.net"},
Created: now,
},
&Item{
Title: "Logic-less Template Redux",
Link: &Link{Href: "http://jmoiron.net/blog/logicless-template-redux/"},
Description: "More thoughts on logicless templates",
Created: now,
},
&Item{
Title: "Idiomatic Code Reuse in Go",
Link: &Link{Href: "http://jmoiron.net/blog/idiomatic-code-reuse-in-go/"},
Description: "How to use interfaces <em>effectively</em>",
Created: now,
},
}
From here, you can output Atom or RSS versions of this feed easily
atom, err := feed.ToAtom()
rss, err := feed.ToRss()
You can also get access to the underlying objects that feeds uses to export its XML
atomFeed := &Atom{feed}.AtomFeed()
rssFeed := &Rss{feed}.RssFeed()
From here, you can modify or add each syndication's specific fields before outputting
atomFeed.Subtitle = "plays the blues"
atom, err := ToXML(atomFeed)
rssFeed.Generator = "gorilla/feeds v1.0 (github.com/gorilla/feeds)"
rss, err := ToXML(rssFeed)

// Package errors provides simple error handling primitives.
//
// The traditional error handling idiom in Go is roughly akin to
//
// if err != nil {
// return err
// }
//
// which applied recursively up the call stack results in error reports
// without context or debugging information. The errors package allows
// programmers to add context to the failure path in their code in a way
// that does not destroy the original value of the error.
//
// Adding context to an error
//
// The errors.Wrap function returns a new error that adds context to the
// original error by recording a stack trace at the point Wrap is called,
// and the supplied message. For example
//
// _, err := ioutil.ReadAll(r)
// if err != nil {
// return errors.Wrap(err, "read failed")
// }
//
// If additional control is required the errors.WithStack and errors.WithMessage
// functions destructure errors.Wrap into its component operations of annotating
// an error with a stack trace and an a message, respectively.
//
// Retrieving the cause of an error
//
// Using errors.Wrap constructs a stack of errors, adding context to the
// preceding error. Depending on the nature of the error it may be necessary
// to reverse the operation of errors.Wrap to retrieve the original error
// for inspection. Any error value which implements this interface
//
// type causer interface {
// Cause() error
// }
//
// can be inspected by errors.Cause. errors.Cause will recursively retrieve
// the topmost error which does not implement causer, which is assumed to be
// the original cause. For example:
//
// switch err := errors.Cause(err).(type) {
// case *MyError:
// // handle specifically
// default:
// // unknown error
// }
//
// causer interface is not exported by this package, but is considered a part
// of stable public API.
//
// Formatted printing of errors
//
// All error values returned from this package implement fmt.Formatter and can
// be formatted by the fmt package. The following verbs are supported
//
// %s print the error. If the error has a Cause it will be
// printed recursively
// %v see %s
// %+v extended format. Each Frame of the error's StackTrace will
// be printed in detail.
//
// Retrieving the stack trace of an error or wrapper
//
// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
// invoked. This information can be retrieved with the following interface.
//
// type stackTracer interface {
// StackTrace() errors.StackTrace
// }
//
// Where errors.StackTrace is defined as
//
// type StackTrace []Frame
//
// The Frame type represents a call site in the stack trace. Frame supports
// the fmt.Formatter interface that can be used for printing information about
// the stack trace of this error. For example:
//
// if err, ok := err.(stackTracer); ok {
// for _, f := range err.StackTrace() {
// fmt.Printf("%+s:%d", f)
// }
// }
//
// stackTracer interface is not exported by this package, but is considered a part
// of stable public API.
//
// See the documentation for Frame.Format for more details.
