<div dir="ltr"><div><div><div>Hi,<br><br>I'm working on an rss file getter. I was wondering if I could get some help getting files to download and save without holding the entire file in memory in between. I chose Conduit's version of SimpleHttp only because it was recommended, and it was the quickest
thing I could get to work correctly because I was eager to get started
on this project, so I'd be happy to switch.<br><br></div><div>Here's where I define the download and save functions:<br><br><a href="https://github.com/orblivion/feedGetter/blob/master/rss.hs#L107">https://github.com/orblivion/feedGetter/blob/master/rss.hs#L107</a><br>
<br></div><div>And here's where I use them, getting multiple at a time with async:<br></div><div><br><a href="https://github.com/orblivion/feedGetter/blob/master/rss.hs#L208">https://github.com/orblivion/feedGetter/blob/master/rss.hs#L208</a><br>
</div><div><br></div><div>What happens when I run this is that it outputs that it's "Getting" the file, waits a while (presumably to download the whole thing), then says it's "Saving". And I checked the file system, it's not there during the pause. I'm not entirely sure why. Is it my choice of libraries, or the way I'm using them? Perhaps something to do with async? I just tried content <- simpleHttp "<a href="http://google.com">http://google.com</a>" in ghci, and it does pause for a second, so I'm guessing this is strict from the getgo. But I've done almost no I/O before.<br>
</div><br>Is there a straightforward, canonical option? It seems like there perhaps should be. But if it comes down to using pipes or conduit, what the heck I'll try it out, I'd like to learn pipes eventually.<br>
<br></div>Thanks a lot,<br><br></div>Dan<br></div>
