scripting / river4 Goto Github PK

I used back ticks to set my fspath environment variable...

 export fspath=`pwd`

This results in a path without a trailing slash, something like...

/Users/davewiner/river4data

Running with such a path results in an error:

river4.js:1216
        for (var i = 0; i < list.length; i++) {
                                ^
TypeError: Cannot read property 'length' of undefined
    at .../river4/river4.js:1216:27
    at Object.oncomplete (fs.js:107:15)

I've not dug in but I'm guessing the path to the lists dir is generated something like: fspath + "lists".

Better would be to use path.join.

tried to host the river4data on github pages as per https://github.com/whizzrd/river4data but I'm not getting any results I didn't have enough patience to wait for it to generate the rivers.

Hi all,
I just started to toy around with river4 today. Setup went basically smooth, but, when opening the river displayer through the Amazon S3 management tool, I got a broken view:

This is because Amazon by default opens the index.html through https (https://s3.amazonaws.com/river4-michael-kamleitner/index.html), and the displayers tries to include JS/CSS through insecure http (check the javascript console on chrome inspector or similar for details).

Should be easy to fix, once the domains fargo.io & static.newsriver.org support https (they don't, right now). In the meantime this is an issue potential newbies (like me) might fall over, so a notice in the README might be good!

I'm setting up river4 on a CentOS 5 Linux server that runs node v0.12.2. fspath is set and river4data exists in the home directory. I'm running node river4.js and I get:

River4 v0.109 running on port 1337.

Before that I had an error ENOENT error and it seemed that those files here were needed:
https://github.com/scripting/river4/blob/master/river4.js#L2815-L2823
So I created all those files manually but now I get parseJson errors because those files are empty of course.

What's going on here? The instructions say that only opml files in river4data/lists/ are required (I use the demo files). Shouldn't river4data/data be populated automatically by the server?

Adam Monago commented on the River4 list that his River4 install using S3 did not save index.html to S3 storage. It appears that the calls to copyIndexFile in river4.js were removed in the first commit on 0.117. These calls should be restored so that River4 users using S3 storage will be able to publish a working River4 site using S3.
