So it has no debugging coupling? Then it sounds like an editor and not and IDE. (But I know that that distinction is often confusing and people but the limit differently.)
Yep, just an editor. There is a debgger plugin, but only for C/C++. You won't find good FPC-oriented IDE under Linux and Windows, so the only variant - Lazarus. Or old version of Eclipse with Pascaline plugin(but I haven't tried it yet).
