Now that the formatting of the classes themselves are complete, I’d like to point out one more issue, and that’s file formatting. If you’re editing all the external classes by hand on the BIG-IP, you have nothing to worry about. However, if you edit them on an external system and copy them over, be careful on which editor you choose. The Unix/Linux line terminator is a line feed (0x0A) whereas Windows default is a carriage return/line feed (0x0D0A) and Mac typically employs just a carriage return (0x0D). The file needs to be formatted in unix-style. I use gVim on my windows laptop. By default, it uses the dos-style, as evidenced in my hex readout in gVim below:i think it's. i just noticed there is an option in textpad to save file in pc (default), unix or mac format. when using pc format, winhex shows line terminator is CRLF as Jason mentioned.
