So, to kick this blog off to a fun start, I'm going to announce a new series (or rather, related posts) called Tech 101. This is designed to be an introduction/how-to for using some pieces of technology (mostly software) that I have found useful, but that might be a bit hard to figure our or unapproachable for people who are trying it for the first time. Today, we're gonna talk about Snownews, which is a command-line feed reader. Snownews is surprisingly effective at what it does, while being quite lightweight resource-wise as well.

What on earth is a feed reader?

Anyone who spends any amount of time on the Internet knows that content can be a pain to keep track of. You'll often have sites (blogs, news sites, possibly other stuff) with content that renews periodically. Sometimes, those periods are predictable; sometimes, they're not. Once you get beyond just a few of these, you commonly end up with a few problems:

  1. You end up spam-checking the site in question just in case something new came up. This is great for their advertising, but not so much for your time - you end up doing this habitually or just because you're bored, wasting valuable productive hours.
  2. If the site has a lot of content on it, it might be worth keeping track of what you've looked at and what remains. You may not have enough time to go through ten new articles - it'd be good to just read two, but then still know which ones you've missed.
  3. Having everything in one place is easier; instead of having to navigate to multiple pages or services, you can just find them all in one spot.
  4. You don't have to rely on stuff that you don't control (beyond the fact that the content is hosted elsewhere). Youtube is a great example of this - a reason many people have Google+ accounts is just so they can monitor their favourite channels. With a feed reader, this becomes unnecessary (and frankly, the more people ditch Google+, the better).

Feed readers are designed to solve all of the above. Essentially, they do a simple job: given a list of places to 'watch', they monitor for when they have new content, and let you know where and what it is, as well as having links to it. By simply loading up all of this stuff into such a program, you can now go about your day, not having to worry whatsoever about missing a thing. You can also concentrate all of your content-browsing into one or two times a day, and you never have to worry about losing your place or forgetting what you have and haven't seen.

Sounds pretty good? I certainly think so - I'm not sure where I'd be if I couldn't use feed readers. While they're certainly not without their downsides, feed readers help keep you more focused, more productive, and in my opinion, more sane. Snownews is a really good example of such a feed reader, due to its simplicity, flexibility and lack of bloat.

Why CLI?

Command-line applications have a bit of a bad rep in some areas; they're considered to be hard to learn, hard to use, and generally unsightly. I disagree with that - I believe that command-line applications can actually be easier to use, easier to learn, and considerably more powerful than graphical ones for many tasks. On top of that, a command-line interface (CLI) doesn't burn up insane resources, and doesn't require you to even have a monitor connected to the computer on which you run them. This allows you to trivially work with them remotely, without relying on someone else's (probably proprietary, probably surveillance-loaded, and probably awful) service via the web.

Snownews has a pleasant CLI, with a lot of help when you need it. If you've never used a CLI application before, Snownews is a really good way to get into it.

Getting started with Snownews

"OK Koz, I get it - Snownews is amazing! Tell me how to do stuff with it already!"

First-off, you'll need to install it. If you're on a Linux-based something or a BSD, you can easily do this via your package manager; if you're on a Mac, I would suggest learning how to Homebrew; if you're on Windows, first, my sympathies, and secondly, Snownews won't work for you, so consider switching to something better!

Once you've installed Snownews, just run it from a terminal with the snownews command. You'll be presented with a big empty window. If so - great! One useful thing to note - if you're ever not clear how to do something, just press the h key to bring up a nice help window, which will likely resolve 90% of your issues.

Let's get some content going. When we add some feeds, they'll appear in this main window. However, adding them is a little bit trickier, because we need a helper program to do it. For now, exit out of Snownews using q. The program you will need is curl, which is a helper for downloading almost anything. We will use it to fetch content for us. Once again, getting it set up shouldn't be a problem on anything where Snownews will run. To make sure it works once you've installed it, type the following into the terminal:


If you get HTML in your terminal, then everything is fine. Get back into Snownews; it's time to add our first feed. We're going to add the feed for Everyday Feminism so that we can keep track of their interesting and educational articles. To do so, we need to find their RSS feed page. This is quite easy to do: just view their home page source, search for the string 'rss', and you'll see the link there. What we need to do is tell Snownews how we go about fetching it. To do that, we need to use the exec command in the pop-up we got from pressing a. Specifically, we want to write the following:


This tells Snownews something like "to fetch this feed, run the command after the colon". This can be arbitrary shell code - you can use your own scripts if you want, as long as the result produces a feed that Snownews can make sense of. After we've entered that, press the Enter key, and Snownews will add the feed. It will now show up on the main screen, with the default 10 new entries marked as unread. To read the feed, just highlight it with the arrow keys, then press Enter. To go back, press q. It's really easy! You'll now have the ability to see what new content has appeared there, in reverse-chronological order (i.e. newest first), along with links.

Once you've read everything, you may want to refresh feeds periodically. You can do that per-feed using r (which will refresh the highlighted feed) or R to refresh all of them!

Going further with feeds

Unfortunately, Snownews cannot read every type of feed - it can handle RSS, but not Atom. Luckily, we can get around that problem pretty easily. Just like Snownews can execute arbitrary commands to retrieve feeds and content, it can also execute arbitrary commands on the result of whatever it fetched. As with the previous issue of getting feeds to us, we're going to need a helper program for this called xsltproc. It shouldn't be hard to retrieve, just like previously. Make sure you have it set up before we start.

To help us work with Atom feeds, we're going to use a script called atom2rss, written by the kind René Puls. You can find the text of the script here, or practice your curl by doing the following (all one line):

curl > atom2rss

Make sure you remember where you put the script - you're going to need it for the next part. Let's now add our second feed, this time for Eevee's blog, for his hilarious take on technology, games and many other things besides. Press a, then enter


Snownews won't be happy with that, but it will ask us if we want a filter script. Press y, then enter the following:

xsltproc /path/to/atom2rss -

That dash is important, so don't omit it! With that, you'll notice that we've now added Eevee's blog feed without any issues. In general, if you're having trouble adding a feed, try sending it through atom2rss - it'll fix most issues.

Turning Youtube into feeds

Now let's do something a bit more interesting - use Snownews to monitor Youtube channels, or even individual playlists of those channels. First-off, we need to know how to get RSS feeds from Youtube channels and playlists. The former is surprisingly easy: go to the channel page, view its source, and search for the string 'rss' - you'll find the link there. You will need to use atom2rss on it, and now, you will have a way of knowing when the next Wanda Melodious video featuring her unique brand of feminist critique of mid-to-late-90s JRPGs will be up!

Following individual playlists like this is harder, but still possible. Let's suppose you wanted to follow The Jimquisition - Jim Sterling's teardown of games media, games publishers and shittiness in the game industry. However, you're not quite so interested in Jim making fun of awful games, so you want to just hear about The Jimquisition. Using the method described here, we can get a feed for just that playlist; to add it, use the following (all one line):


You'll need to pass it through atom2rss as well. Now, you have all the benefits of Google+ for Youtube, without the EULAs, surveillance and other awfulness. Isn't it great?

Going further

With the combination of Snownews and command-line tools, you can do some amazing things. Check out the helper script repository for Snownews for ideas! I hope that it will be as useful to you as it is to me. If you wanna get started, why not follow my feed?
