Scripting language by Commodore International, derived from the LISP programming language
Installer is a scripting language developed by Sylvan Technical Arts and published by Commodore International for AmigaOS, first released for version 2.1 in 1992.[1] Its grammar is based on the LISP programming language. A compatible re-implementation named InstallerLG is actively developed as of October 2018.[2]
Example from the developer guide:
(makedir"T:fred"(prompt"I will now create the directory \"T:Fred\"")(help@makedir-help)(infos)(confirm))
The InstallerGen tool can be used as an alternative for writing scripts by hand.[3]
