Sometimes you may have standard line lengths with which to work when writing code. If this is the case and your using Coldfusion and Eclipse with the cfEclipse plugin you can maintain the character length consistency by setting up the print margins to n character length.

Point being that when running the cfeclipse plugin you need to choose CFEclipse > Editor in the preferences left navigation. In the options you will check ‘Show print margin’, set the ‘Print margin column’ text field to the desired character length, and if you choose the ‘Print margin’ option in the ‘Appearance color options’ select box. Then choose the color you wish the margin to be. This will set a line length that will show in the code editor pane. Of course it will not wrap the line. It is still your duty as a developer to wrap appropriately. Nonetheless it does give you a guide for where the line should wrap at least.

If you’re writing Java then you would select General > Editor > Text Editors in the preferences pane.  Although the display is slightly different, generally follow the same steps as above for showing the print margin.

If you’re using Coldfusion Builder you will follow the same exact directions as listed just above for showing the print margins writing Java.

Lastly, if you’re using Flex Builder 3 you will again follow the same directions as above for showing print margins writing Java.
