How To Send A Tweet From Max/MSP { sound + tutorial }

22Apr09

First off, a big thanks to Matthew Eddey for helping with the Ruby script and Twitter API. Also to all the people that helped along the way.

This should work on Max 5 and Mac OS and Window.

how to send a tweet directly from Max/MSP

I used the Ruby programming language to access Twitter’s API. To use Ruby within Max/MSP you need to download the [ajm.ruby] external by Adam Murray. After downloading, follow the “INSTALL.txt” instructions to correctly install it.

This is not necessary, but if you want to count the remaining characters you need to download the [strlen] external by Jasch and put it in Max’s search path.

Finally, download the MaxToTwitter patch.

That should be it, enjoy sending tweets from Max!

If you use it in a project don’t be shy to include my name or link back to here

Just checked Max 5 on Windows, works great! Now I can tweet on stage w/o leaving Max5!! Keep up the good work!

Awesome! Thanks for letting me know. I’ll update the post.

This is rad. Glad to see my software is being put to cool uses! If you run into any issues with ajm.ruby or have thoughts on ways to enhance it, don’t hesitate to drop me a line. I’ll be releasing an update soon-ish with a new JRuby version that is faster and more efficient than the current version.

Adam, thanks so much for making ajm.ruby available!!! Let me know when the update is ready, and I’ll update TAS. And thanks for the comment.

I’m trying to use this patch, but it doesn’t seem to be working – I keep getting the error message

ajm.ruby: could not evaluate: $message = whatever

However, I tried the Tweet-A-Sound app and I am able to tweet from that just fine.. Is there any difference between the standalone patch and the patch you use within tweet-a-sound?

Any help would be much appreciated.

Thanks a lot

Hi Aaron, can you give a bit more details? What setup are you on? Is the problem happening once you build a standalone or through Max? Are you sure you installed [ajm.ruby] correctly? Maybe open the [ajm.ruby] help patch and test it?

It’s working with me as a patch. I’m on Snow Leopard, it also worked on Leopard. However, I’ve been working on an other application, which uses a similar setup and is not working when building standalones. It might be an issue when using java in Max on Snow Leopard, I need to email Cycling ‘74 for more info.

I’m running the patch through max 5.1 on snow leopard.. haven’t tried making a standalone. ajm.ruby seems to be installed correctly, the help patches for it work and everything. Everything seems to run okay but it doesn’t like the “$message = x” message.. Strange

umm… same as me. I’m not sure then. It could be that when you type it is not entered into the message boxes. Maybe try type your message and password and username and then click again on each and hit enter to make sure they get put into the code. It should look like: [$message = yourmessage]

If you look into the Twitter subpatch, you should see all the info you put into the text boxes being entered into the red message boxes. Did you try change the message manually?

hi Aaron and Andrew,
I had same thing but i figured out what was happening. Maybe $message has to have double-quated text. But when the input text is just one word like “whatever”, textedit object outputs without ” ” between the word. 2 more words like “whatever text” will be output as , so you can try with 2 more words!

13 Andrew Spitz on Dec 4th, 2009 said:

Haha, yes. I remember now, totally forgot about that. It doesn’t work with just one word… It didn’t matter for me because I always use it with more than one word.

if you want to be able to use it with just one word, you can probably just use [sprintf] to add a space before or after.

Hey guys, I get a funky message when trying to send:

ajm.ruby: could not evaluate: require ‘net/http’ require ‘uri’ $url = $url.delete(’ ‘) puts $url res = Net::HTTP.post_form(URI.parse($url), {’status’ => $message}) if res.code == ‘200′ then out1(Sent!) else out1(Error! (#{res.code}: #{res.message})) end

Any ideas?

Thanks, this is a crazy patch
15 Joe on Jan 28th, 2010 said:

I get this message “could not evaluate” from the ajm.ruby external every time I try to send it anything, even from the help files… Troublesome.
16 Andrew Spitz on Feb 4th, 2010 said:

Hi Joe, sorry for the delay in replying. Been very busy and with limited access to internet. I don’t have time to look at it in detail, but off the top of my head, there are a few things that could be doing this.

Make sure that you have at least 2 words in your message, if not just add a space. It’s a stupid bug that I could fix (check the comment above) but it will be for some other day.

Are you sure you installed the [ajm.ruby] stuff correctly? That could also be the problem.

Try these suggestions, and if it still doesn’t work don’t hesitate to message again with what OS you’re using.

Hope you get it working

Thanks Andrew,

Actually I’ve been emailing with Adam and I think its an issue with the newest update of Max and the ruby object. Hopefully he’ll have some time to fix it, and it gets resolved, but for now, i think one must remain on the previous version of Max to get this to work.

Thanks again!

Oh, good to know! Thanks for telling me. cause I need some of the ajm objects for something I’m soon compiling… so I won’t update! Curious to see what you’re up to if you wanna share.
