How can I close a Window using the OS-X ScriptingBridge framework, from Perl?
- by Gavin Brock
Problem...
Since MacPerl is no longer supported on 64bit perl, I am trying alternative frameworks to control Terminal.app.
I am trying the ScriptingBridge, but have run into a problem passing an enumerated string to the closeSaving method using the PerlObjCBridge.
I want to call:
typedef enum {
TerminalSaveOptionsYes = 'yes ' /* Save the file. */,
TerminalSaveOptionsNo = 'no ' /* Do not save the file. */,
TerminalSaveOptionsAsk = 'ask ' /* Ask the user whether or not to save the file. */
} TerminalSaveOptions;
- (void) closeSaving:(TerminalSaveOptions)saving savingIn:(NSURL *)savingIn; // Close a document.
Attempted Solution...
I have tried:
#!/usr/bin/perl
use strict;
use warnings;
use Foundation;
# Load the ScriptingBridge framework
NSBundle->bundleWithPath_('/System/Library/Frameworks/ScriptingBridge.framework')->load;
@SBApplication::ISA = qw(PerlObjCBridge);
# Set up scripting bridge for Terminal.app
my $terminal = SBApplication->applicationWithBundleIdentifier_("com.apple.terminal");
# Open a new window, get back the tab
my $tab = $terminal->doScript_in_('exec sleep 60', undef);
warn "Opened tty: ".$tab->tty->UTF8String; # Yes, it is a tab
# Now try to close it
# Simple idea
eval { $tab->closeSaving_savingIn_('no ', undef) }; warn $@ if $@;
# Try passing a string ref
my $no = 'no ';
eval { $tab->closeSaving_savingIn_(\$no, undef) }; warn $@ if $@;
# Ok - get a pointer to the string
my $pointer = pack("P4", $no);
eval { $tab->closeSaving_savingIn_($pointer, undef) }; warn $@ if $@;
eval { $tab->closeSaving_savingIn_(\$pointer, undef) }; warn $@ if $@;
# Try a pointer decodes as an int, like PerlObjCBridge uses
my $int_pointer = unpack("L!", $pointer);
eval { $tab->closeSaving_savingIn_($int_pointer, undef) }; warn $@ if $@;
eval { $tab->closeSaving_savingIn_(\$int_pointer, undef) }; warn $@ if $@;
# Aaarrgghhhh....
As you can see, all my guesses at how to pass the enumerated string fail.
Before you flame me...
I know that I could use another language (ruby, python, cocoa) to do this but that would require translating the rest of the code.
I might be able to use CamelBones, but I don't want to assume my users have it installed.
I could also use the NSAppleScript framework (assuming I went to the trouble of finding the Tab and Window IDs) but it seems odd to have to resort to it for just this one call.
