; fileassoc.nsh
; File association helper macros
; Written by Saivert
;
; Features automatic backup system and UPDATEFILEASSOC macro for
; shell change notification.
;
; |> How to use <|
; To associate a file with an application so you can double-click it in explorer, use
; the APP_ASSOCIATE macro like this:
;
; Example:
; !insertmacro APP_ASSOCIATE "txt" "myapp.textfile" "Description of txt files" \
; "$INSTDIR\myapp.exe,0" "Open with myapp" "$INSTDIR\myapp.exe $\"%1$\""
;
; Never insert the APP_ASSOCIATE macro multiple times, it is only ment
; to associate an application with a single file and using the
; the "open" verb as default. To add more verbs (actions) to a file
; use the APP_ASSOCIATE_ADDVERB macro.
;
; Example:
; !insertmacro APP_ASSOCIATE_ADDVERB "myapp.textfile" "edit" "Edit with myapp" \
; "$INSTDIR\myapp.exe /edit $\"%1$\""
;
; To have access to more options when registering the file association use the
; APP_ASSOCIATE_EX macro. Here you can specify the verb and what verb is to be the
; standard action (default verb).
;
; And finally: To remove the association from the registry use the APP_UNASSOCIATE
; macro. Here is another example just to wrap it up:
; !insertmacro APP_UNASSOCIATE "txt" "myapp.textfile"
;
; |> Note <|
; When defining your file class string always use the short form of your application title
; then a period (dot) and the type of file. This keeps the file class sort of unique.
; Examples:
; Winamp.Playlist
; NSIS.Script
; Photoshop.JPEGFile
;
; |> Tech info <|
; The registry key layout for a file association is:
; HKEY_CLASSES_ROOT
; <applicationID> = <"description">
; shell
; <verb> = <"menu-item text">
; command = <"command string">
;
