go-hn

go-hn is a hacker news client for the terminal. There's not much to this program code-wise, but this was a another happy surprise from GO as the XML parsing worked the first time.

Quick install: go get github.com/sspencer/go-hn

Features

• Grabs latest hacker news headlines from the Hacker News RSS Feed and displays them in the terminal
• Opens desired article in default browser

Dependencies

• Working Go 1.11 environment
• utf-8 terminal with colors

Setup

• Install the go-hn binary into your $GOPATH with go get github.com/sspencer/go-hn
• Invoked go-hn (assuming go/bin is in your path)
• If you prefer an executable named hn or just want to play and reinstall the code, make sure $GOBIN is set, cd $GOPATH/src/github.com/sspencer/go-hn and type go install hn.go.

Parsing XML

GO makes it SO easy! Just define a few types and away you GO.

type Item struct {
    Title string `xml:"title"`
    Link  string `xml:"link"`
}

type Channel struct {
    Items []Item `xml:"item"`
}

type Result struct {
    Channel Channel `xml:"channel"`
}

body, err := ioutil.ReadAll(resp.Body)
...
var v Result
err = xml.Unmarshal(body, &v)
