We believe in preferences

Style windowIf you "live" in your editor, you will want to feel at home. With SubEthaEdit's Mode-central preference system you can. Want new colors for that Perl file? No problem, you can even share them with others. Want to open HTML files in a bigger window than normal text by default? Go for it. Your PHP files (and only them) should have windows line endings? Easy. For your one-stop customization of everything and all the rest, visit SubEthaEdit's preference panes, located in "SubEthaEdit→Preferences", just where they should be.

Add Scripts

Many parts of SubEthaEdit are scriptable with AppleScript. This includes text and selection manipulation, collaborative features and basic file operations. You can even add your own features to SubEthaEdit, including a toolbar icon and menu items. For instructions and documentation please visit our scripting page.

Make your own

If there is no mode for your favorite language available yet and you aren't afraid of getting your hands dirty a little bit, you can create your very own mode. Just check our extensive mode format documentation including a development kit and make your own set of syntax definition, function popup and autocomplete dictionary to create a custom working environment. If you created a mode, you can also send us an email, so we can put it online for others to use.
