This perl code compiles and runs an apple mac app
that decompiles and prints its own applescript
source code:
Easier to read:
1. Perl setup:
As a script:
perl -Mautodie -we '$app="ApplePerlQuine\@perlmonks.org.app";die"not a +pple mac"unless${^O}eq"darwin";open$f,"|-","osacompile -o $app";print +$f qq~set myPATH to path to me as string\nset myPATH to myPATH & "Con +tents:Resources:Scripts:main.scpt"\nset myPATH to do shell script"ech +o " & myPATH & " | tr : / | sed -E \x27s/Macintosh HD//\x27"\ndisplay + dialog (do shell script ("osadecompile " & myPATH)) with title "$app +" buttons {"Use Perl!"} default button 1\n~;close$f;system("open $app +")'
Easier to read:
perl -Mautodie -we '$app="ApplePerlQuine\@perlmonks.org.app"; die"not apple mac"unless${^O}eq"darwin"; open$f,"|-","osacompile -o $app"; print$f qq~ set myPATH to path to me as string\n set myPATH to myPATH & "Contents:Resources:Scripts:main.scpt"\n set myPATH to do shell script"echo " & myPATH & " | tr : / | sed -E \x27s/Macintosh HD//\x27"\n display dialog (do shell script ("osadecompile " & myPATH)) with title "$app" buttons {"Use Perl!"} default button 1\n ~; close$f; system("open $app")'Easier to understand:
1. Perl setup:
perl -Mautodie -we '$app = "ApplePerlQuine\@perlmonks.org.app"; die "not apple mac" unless ${^O} eq "darwin";2. Open pipe to applescript compiler and print:
open $f, "|-", "osacompile -o $app"; print$f qq~3. Set applescript variable to the app path:
set myPATH to path to me as string\n4. Append path of compiled source (inside the app):
set myPATH to myPATH & "Contents:Resources:Scripts:main.scpt"\n5. Use shell to manipulate the path:
set myPATH to do shell script"6. Change applescript variable with tr and sed:
echo " & myPATH & " | tr : / | sed -E \x27s/Macintosh HD//\x27"\n7. Decompile app and display source code:
display dialog (do shell script ("osadecompile " & myPATH)) with title "$app" buttons {"Use Perl!"} default button 1\n8. Back to perl, end print, close pipe, open app:
~; close$f; system("open $app")'Summary: lines 1-2 and 8 use perl to write the app with applescript in lines 3-7.
As a script:
#!/usr/bin/perl use strict; use warnings; use autodie; die "not apple mac" unless ${^O} eq "darwin"; my $app = "ApplePerlQuine\@perlmonks.org.app"; open my $f, "|-", "osacompile -o $app"; print $f qq~set myPATH to path to me as string set myPATH to myPATH & "Contents:Resources:Scripts:main.scpt" set myPATH to do shell script "echo " & myPATH & " | tr : / | sed -E \ +x27s/Macintosh HD//\x27" display dialog (do shell script ("osadecompile " & myPATH)) with title + "$app" buttons {"Use Perl!"} default button 1\n~; close $f; system("open $app");
This one prints itself entirely, including the perl:
perl -Mautodie -we '$app=qq(ApplePerlQuine\@perlmonks.org.app);die"not + apple mac"unless${^O}eq"darwin";open$f,qq(|-),qq(osacompile -o $app) +;print$f qq(set myPATH to path to me as string\nset myPATH to myPATH +& "Contents:Resources:Scripts:main.scpt"\nset myPATH to do shell scri +pt"echo " & myPATH & " | tr : / | sed -E \x27s/Macintosh HD//\x27"\nd +isplay dialog (\"perl -Mautodie -we \x27\x24app=qq(ApplePerlQuine\134 +\134\100perlmonks.org.app);\nopen\x24f,qq(|-),qq(osacompile -o \x24ap +p);\nprint\x24f qq\(\" & do shell script ("osadecompile " & myPATH)) +& "\);close\x24;system\(\x27\x27open \x24app\x27\x27\)" with title "$ +app" buttons {"Use Perl!"} default button 1\n\(* This is an ASCII rep +resentation of the Perl source used to make this app. It will not cut + and paste because of hex and octal tricks.
