I may be missing something here, but it seems to me that in applescript it is not possible to pass a handler to the 'do script' command, which is the only way to be able to control how InDesign handles undoing your script, it will only accept a string. Is this correct?

Working on the assumption that it is, I'm trying out using the code below to encapsulate scripts so that they call themselves. I've done it because I'm getting tired of making whole scripts into strings and escaping all the quotes within, only to have to un-escape them all it if I want to edit the script and compile it for testing.


property runNow : false -- change this to true to debug
property undoName : "Test undo name"

if runNow then
    -- do stuff
    tell application "Adobe InDesign CS5"
        -- do stuff
    end tell
   
    -- important return statement.
    -- stack overflow without
    return
end if

---- workings
set scriptAlias to (path to me)
set scriptPath to (scriptAlias as string)

set theScript to load script scriptAlias

if not theScript's runNow then
    theScript's toggleRun()
end if

if theScript's runNow then
    store script theScript in (path to me) with replacing
    tell application "Adobe InDesign CS5"
        do script scriptPath undo mode entire script undo name undoName
    end tell
end if

on toggleRun()
    if runNow then
        set my runNow to false
    else
        set my runNow to true
    end if
end toggleRun
---- workings


It's just occurred to me that I could also use a script bundle with the main script calling another script from within it's bundle, which is possibly a more elegant solution.
