How to make a straightforward application from an applescript!

I've obtained an applescript that I make use of to open documents such as test.txt in strength, making use of the terminal.

I generally open a documents by appropriate - clicking it a picking the solution open in vim (this solution is developed by me and also primarily runs the applescript).

Just how do I construct a real program, that can be embeded in the "open with" alternative for a documents?

In this manner, when I double click test.txt, the applescript obtains run and also the documents obtains opened up in my strength in terminal.app.

I would certainly additionally such as to create personalized symbols that will certainly be related to all documents I open utilizing this application (making use of the "Change All ..." switch).

Where would certainly I begin? Is this very easy, due to the fact that I'm simply an amateur - although I enjoy shows and also would certainly invest much to to be familiar with all that is required to do this.

the code is :

on open this_item

    tell application "System Events"
        if (count (processes whose name is "Terminal")) is 0 then
            tell application "Terminal"
                activate
                do script with command "vim " & (POSIX path of this_item) in front window
            end tell
        else
            tell application "Terminal"
                activate
                tell application "System Events" to tell process "Terminal" to keystroke "t" using command down
                do script with command "vim " & (POSIX path of this_item) in selected tab of the front window
