Duplicated StackExchange notifications

[xurizaemon]

Follows from #14

Hubot double-posts some StackExchange questions, which stands out especially badly during quiet periods in Town Square.

We need to:

• [ ] work out why the poller detects the SE feed as having changed when the latest post hasn't - suspect this relates to question edits
• [ ] account for this and/or detect that the previous post on this feed was identical
• [ ] not do that!

xurizaemon/hubot-rss-poller2 is a fork of a module published on NPM - I'm not sure if there's a repo available for contributing back.

(@gobias-nz if you comment with a link to repo I'd love to contribute back fixes like this - looks like the published version on NPM is babel-ified and it would be more useful to contribute to the original code? Would love you to publish that as well!)

Hey @xurizaemon see this - http://npminstall.org/Install-hubot-rss-poller2-using-npm/ - and this - https://github.com/KanoYugoro/hubot-rss-poller - @KanoYugoro any help with tracking down a repo for hubot-rss-poller2 ?

[xurizaemon]

Actually Joe, Kano's looks like it's what Gobias based their work off, so I will see if we can switch to using that - seems like the original repo is active while hubot-rss-poller2 is not updated since 0.0.5 on npm. Good find :)

[joemcl]

Yeah thanks though was wondering why Kano posted the download and install for poller2 rather than poller...

[joemcl]

Anyway, cool

[joemcl]

Maybe poller2 is just v 2 of poller in Kano's repo....

[xurizaemon]

Current status: I switched to xurizaemon/hubot-rss-poller@build which is my fork of KanuYugoro/hubot-rss-poller. It's not working yet, so the dupe posts are "fixed" (ie bolts has stopped posting anything from RSS). Will revisit "soon" :)

I don't understand this comment @joemcl ?

[joemcl]

Kano/Anson Wayman is the author of poller, from which poller2 is forked, apparently. The initial link I found here from him (or perhaps someone else) is to install poller2, the fork that someone else (or a different GitHub account name, at least) modified, via npm, rather than his original poller. However, I just discovered that in fact he (or someone else) posted links to install both versions, on the same day, see here, via npm. Doesn't matter, just thought it was curious. He may be the author of both versions, at least he's credited with both at the npm-install site.

Aha, yeah I believe it goes like this -

• npminstall.org is largely autogenerated and shows a templated set of instructions for any module on https://www.npmjs.com/ - those posts aren't by Anson, as you suspected
• Anson wrote hubot-rss-poller and published the source as that module to npmjs.com
• There's a build step required to use that module in a hubot, because the entry point in package.json is not included in the source (it's instead built with babel as part of publishing)
• Gobias-nz ran into this and worked around it by uploading a copy of Anson's work to npmjs.com, retaining the author in package.json
• I've now hit the same issue with my copy of Anson's work, but am dealing with it by installing from a "build" branch rather than shipping another copy of the module to npmjs.com
• Future me who is not a Babel noob may know how to not require the "build" branch, but this was a quick workaround on the weekend

[joemcl]

OK, now I get it. Not sure what the purpose of that build step using babel is - I see here that babel is a Javascript compiler, I kinda know what a compiler does. Glad you know the workaround :).
