We've all heard this story before. All examples and tutorials look just fine: we can create a new channel, we can send to a channel, we can read from a channel, we even have the nifty, elegant select statement (btw, why do we still have statements in 21th century?), blocking reads and buffers…</p> 8 points posted by kenny https://gist.github.com/kachayev/21e7fe149bc5ae0bd878 2807 Mon, 16 Oct 2017 20:32:00 +0000 <p>This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.</p> <h2><a href="https://gist.github.com/posener/73ffd326d88483df6b1cb66e8ed1e0bd#why-go-is-good-for-scripting" aria-hidden="true" class="anchor" id="user-content-why-go-is-good-for-scripting" style="box-sizing: border-box; color: rgb(3, 102, 214); float: left; padding-right: 4px; margin-left: -20px; line-height: 1;"><svg aria-hidden="true" class="octicon octicon-link" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a></h2> 7 points posted by kenny https://gist.github.com/posener/73ffd326d88483df6b1cb66e8ed1e0bd 2867 Mon, 30 Oct 2017 09:08:00 +0000 5 points posted by gopher https://gist.github.com/bketelsen/87e539c8126b453a0995be73e2e754c6 1399 Wed, 21 Dec 2016 06:51:00 +0000 <p>One common response to the new generics proposal has been that contracts seem a bit too much like interfaces but not the same.</p> <p>They are indeed very similar if you squint a little.
