script

dummy plugin (0 byte file)

compiled version of the script

Description

This is an altered version of the example Winamp plugin installer which makes it easier to generate the installer by altering a few defines for the version, name, plugin file, etc. As well, when run it will automatically close Winamp and on a successful install will give you the choice of to run Winamp with the new plugin or not.

The script is provided as is and I've added a few notes on how the script can be expanded to deal with multiple sections or making it easy to manage your different installer versions. I've also included a test installer of the script and a dummy gen_* file to build it with (the file has no size so it won't cause an problems for Winamp).

Things To Be Done

I will be adding an advanced version of this script soon which adds in an uninstaller, multiple sections and also a 'previous install' option for when the installer is run multiple times.

When you try to run this script in NSIS do not forget to change default plugin name to the actual name of your plugin in this line:

!define PLUG_FILE "gen_fill_me_in"

for example, your plugin is called "gen_my_plugin" so you`ll change the script to

!define PLUG_FILE "gen_my_plugin"

The Script

; This script generates an installer for a Winamp 2.x / 5.x plug-in.
;
; The installer will automatically close Winamp if it's running and then if
; successful, ask the user whether or not they would like to run Winamp with
; the newly installed plug-in.
;
; This is a single section installer but is easily altered for multiple
; sections and is based of the original Winamp installer script but tweaked
; to be easier to use i think :o)
