Is there a way to decompile a run-only script back?

Scripting Forums AppleScript | Mac OS X
#1

I need to edit its code but forgot to make a backup editable copy of it. I know that usually there’s no way back, but maybe there’re some exotic methods to try?

Model: MacBook Pro
AppleScript: 2.2.1
Browser: Safari 534.57.7
Operating System: macOS 10.7

Sadly, you’re out of luck.

#3

Maybe, THIS DISASSEMBLER?

The author of the code promises a lot, but I have not tried it myself yet.

#4

As I am curious, I installed the disassembler.

I tried to use it with :

set CLI to POSIX path of ((path to home folder as text) & "applescript-disassembler:disassembler.py")

set theFile to quoted form of POSIX path of ((path to desktop as text) & "Sans titre Run-Only.scpt")

do shell script CLI & space & theFile

I just got : error “env: python2: No such file or directory” number 127
and don’t know what to do with that.

You can use it by running disassembler.py at the command line, but first you must make it executable using something like chmod +x. On a simple test script with just a display dialog “Hello”, I got:

=== data offset 2 ===
Function name : <Value type=object value=<Value type=event_identifier value=‘aevt’-‘oapp’-‘null’-‘\x00\x00\x80\x00’-‘****’-‘\x00\x00\x90\x00’>>
Function arguments:
00000 PushLiteral 0 # [, ]
00001 Push0
00002 MessageSend 1 # <Value type=object value=<Value type=event_identifier value=‘syso’-‘dlog’-‘askr’-‘\x00\x00\x00\x00’-‘TEXT’-‘\x00\x00\x00\x00’>>
00005 Return

I don’t think that’s the sort of thing the OP was hoping for.

Thank you.
On my machine I found only python2.7 and got the same error when trying in Terminal.
