Editing Plug-in (computing) (section)

==History==
In the mid-1970s, the [[EDT (Univac)|EDT]] [[text editor]] ran on the [[Unisys]] [[VS/9]] [[operating system]] for the [[UNIVAC Series 90]] [[mainframe computer]]. It allowed a program to be run from the editor, which can access the in-memory edit buffer.<ref>''EDT Text Editor Reference Manual'', [[Cinnaminson, New Jersey]]: [[Unisys Corporation]], 1975</ref>  The plug-in executable could call the editor to inspect and change the text. The [[University of Waterloo]] Fortran compiler used this to allow interactive compilation of [[Fortran]] programs.

Early personal computer software with plug-in capability included HyperCard and [[QuarkXPress]] on the [[Apple Macintosh]], both released in 1987. In 1988, [[Silicon Beach Software]] included plug-in capability in [[Digital Darkroom]] and [[SuperPaint (Macintosh)|SuperPaint]].
