After a single quote, the *only* character that has a special meaning is
another single quote, which ends the quotation. Double quotes, back slashes,
dollar signs, exclamation marks, et al. have absolutely no special significance
between single quotes..
Thus, the simplest way to safely quote an arbitrary string is to preprocess the
string to replace each single quote (') with the sequence single quote,
backslash, single quote, single quote ('\''), and then wrap the resulting
string in single quotes.
As an (unnecessary) refinement, scan that sequence again, replacing each
sequence of three consecutive single quotes with one, to shorten the string
that results when the original string contained consecutive single quotes. As
another (unnecessary) refinement, pre-scan the original string to see if it
contains only safe characters, in which case no quoting needs to be done at
all. It's probably not worth bothering to do either of these.
Almost as easy to program, but generally producing longer quoted strings, is to
prepend a backslash to any character that is not a lowercase letter or a digit.
Do not wrap the resulting string in any kind of quotes. (Non-ASCII characters
are never special to the shell, but I'm not sure what would happen if you
inserted backslashes in the middle of a multi-byte character, nor whether the
behavior will change in later versions of the shell, so be sure you're
prepending backslashes to characters, not bytes.)

Open a new terminal tab or window from a Cocoa app at a certain directory without using NSAppleScript?
I would like to perform the same logic as the New Terminal Tab at Folder service in Finder in my Cocoa app. The only code I found via Google is all using AppleScript to open the Terminal.app, but nothing I found was a Cocoa interface besides 3rd party terminal apps (iTerm, iTerm2). Is there a better way than using NSAppleScript to do this? I do not see any core libraries for the terminal app, but perhaps I am just looking in the wrong location. If I were to use NSWorkspace, I tried using the open at the command line, but I am not able to: 1. figure out how to open a new tab as opposed to a window 2. not have to run a program 3. it does not open the default terminal theme Thanks, Andrew ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Open a new terminal tab or window from a Cocoa app at a certain directory without using NSAppleScript?
Well, I found this: http://code.google.com/p/cdto/source/browse/plugins/terminal/CD2Terminal.m?spec=svn20c4d028f197a6810230ddff969de81c4b23876dr=20c4d028f197a6810230ddff969de81c4b23876d And got the terminal opening in a new window at the path. So I now need to find how I can set the settings and have it open a new tab instead of window.

Re: Open a new terminal tab or window from a Cocoa app at a certain directory without using NSAppleScript?
Well, I figured it out for myself. Posting here in case anyone else
wants to do the same:
- (void)openTerminal:(id)sender
{
TerminalApplication* termApp = [SBApplication
applicationWithBundleIdentifier:@com.apple.terminal];
NSString *dir = // Get your directory here
NSString *cmd = [NSString stringWithFormat:@cd \%@\; clear,
dir]; // Assumes bash, which is okay for me, but maybe not others.
TerminalWindow *window = nil;
if (termApp.windows.count 0)
{
// Use the first window:
window = [termApp.windows objectAtIndex:0];
}
TerminalSettingsSet *settings = [termApp startupSettings];
TerminalTab *newTab = [termApp doScript:cmd in:window];
[newTab setCurrentSettings:settings];
[newTab setSelected:YES];
[termApp activate];
}
