Installer is a scripting language developed by Sylvan Technical Arts and published by Commodore International for AmigaOS. It was first introduced in version 2.1 of AmigaOS in 1992.[1] Its syntax is based on the LISP programming language.
A compatible re-implementation, InstallerLG, remains under active development as of October 2018.[2]
The following example, taken from the developer guide, demonstrates directory creation with user prompts:
(makedir "T:fred" (prompt "I will now create the directory \"T:Fred\"") (help @makedir-help) (infos) (confirm) )
The InstallerGen tool provides a graphical alternative to writing scripts manually.[3]
