Question

I’m using this plist gem to generate a plist file, which my Rails application will output to user if the request is http://myrailsapp/something.plist

the code responsible for this is pretty simple. (controller)

if @package.present?
   format.html
   format.plist { render :text => @package.to_plist }

view it im Vim, gives

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>uninstall_script</key>
        <string>#!/bin/sh^M
        ^M
        echo &quot;Test&quot;^M
        ^M
        exit 0^M
        </string>
        <key>uninstallable</key>
        <true/>
        <key>version</key>
        <string>4.7</string>
</dict>
</plist>

On every string line end with a ^M

when I try to debugger this in rails console, it outputs just fine

<key>uninstall_script</key>\n\t<string>#!/bin/sh\r\n\t\r\n\techo &quot;Test&quot;\r\n\t\r\n\texit 0\r\n\t</string>\n\t

No ^M to be find. So any suggestions on where I should look for this issues ?

When the plist that has ^M at the end of the line, another program that reply on this plist doesn’t read it properly. And when I try to remove the ^M manually it works just fine.

Thanks to mu is too short

pointing out that \r is actually the cause of ^M. In that case, I’ve just fixed this bug !!

Pretty simple fix just add the following inline to over write the to_plist method

plist.gsub(/\r\n?/, "\n")

And that just did the job I wanted
