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]
