AppleScript path relative to script location

Question

I'm trying to launch a Finder window of a folder that's in the same directory as my script. When I run the code below, it launches a blank Finder window set to the path of the script not to the folder.

tell application "Finder"
    tell application "Finder" to make new Finder window
    set file_path to (path to me) as text
    set target of Finder window 1 to file_path
end tell

How can I get the path to the folder of the script, not the script?

Answer 1

You were close. You do not need the text version of the file, you only need the file itself, then you can ask Finder for that file's container:

tell application "Finder"
    tell application "Finder" to make new Finder window
    set file_path to (path to me)
    set target of Finder window 1 to file_path's container
end tell

Answer 2

The shortest way I know to do this is:

tell application "Finder" to open ((path to me as text) & "::")

Editing your script renders the following:

tell application "Finder"
    make new Finder window -- There is no need for an your second tell statement
    set file_path to (path to me as text) & "::" -- Goes up one directory
    set target of Finder window 1 to file_path
end tell
