Unwanted empty lines in the resulting HTML files.

Hey all,

I got a weird issue where my Ruby tags looking like this: <% (something) -%> actually produces empty lines once I put them on my webhost. Locally while I develop I don't get them at all. This is really annoying as the resulting HTML code looks really messed up.

I have frozen Rails, so it's the exact same Rails code being run locally as well as in production. What might cause this problem? Known bug? Is there any other way to stop if statements and ends to create blank lines?

Thanks, Mathias.

I thought the dash would force that line to not produce any blank lines. Isn't that the feature? I guess I'll try without it, can't hurt. :slight_smile:

Thanks, Mathias.

Just tried this and it made no difference.

I'm developing the project under Windows (in RadRails) and it is deployed to a Linux server. Could it be some end-of-line delimiter that's different between the OSes that's causing this bug? I can't be the only one suffering from this?

Yeah. I used to have this problem. I think it’s definitely an issue with Windows line-endings. I solved it by [ack] editing the files on the server [with pico/nano]. Now I develop on Linux so there’s no issue. I don’t think.

I looked into this a bit more and it seems like one problem is that if you comment out the line, for example: <% # if whatever? -%> then it will still produce an empty line. But there were other places where the problems disappeared once I started editing the files on the server to try it out. So it might be a combination. Will keep it in mind though, will help me with the trouble shooting if it happens again.

Thanks, Mathias.
