    <p>No, Go does not provide a REPL.</p> <p>However, as already mentioned, <a href="http://play.golang.org/" rel="nofollow noreferrer">Go Playground</a> (this is the new URL) is very handy. The Go Authors are also thinking about adding a feature-rich editor to it.</p> <p>If you want something local, consider installing <a href="http://labix.org/hsandbox" rel="nofollow noreferrer">hsandbox</a>. Running it simply with <code>hsandbox go</code> will split your terminal screen (with <code>screen</code>) where you can write code at the top and see its execution output at the bottom on every save.</p> <p>There was a <code>gotry</code> among standard Go commands, which used to evaluate expressions (with an optional package name), and could be run like <code>gotry 1+2</code> and <code>gotry fmt 'Println("hello")'</code> from shell. It is no longer available because not many people actually used it.</p> <p>I have also seen third party projects for building a REPL for Go, but now I can only find links to two of them: <a href="https://github.com/sbinet/igo" rel="nofollow noreferrer">igo</a> and <a href="https://github.com/vito/go-repl" rel="nofollow noreferrer">go-repl</a>. How well do they work I don't know.</p> <p>My two cents: Speed of compilation makes writing a REPL possible for Go, as it has also helped building the tools mentioned here, but the same speed makes REPL less necessary. Every time I want to test something in Go that I can't run in Playground I open a simple <code>.go</code> file and start coding and simply run the code. This will be even easier when the <code>go</code> command in Go 1 makes one-command build process possible and way easier.</p> <p><strong>UPDATE:</strong> Latest weekly release of Go added <code>go</code> command which can be used to very easily build a file: write your <code>prog.go</code> file and run <code>go build prog.go &amp;&amp; ./prog</code></p> <p><strong>UPDATE 2</strong>: With Go 1 you can directly run go programs with <code>go run filename.go</code></p> <p><strong>UPDATE 3</strong>: <a href="https://github.com/motemen/gore" rel="nofollow noreferrer"><code>gore</code></a> is a new project which seems interesting.</p>

    3. COTL;DR igo Others: Gore isn't very convenient as it requires pasting and Ctrl-D. Something like Reinteract for Go would be awesomesauce.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
