Question

我想从C ++程序执行Applescript命令tell application "Finder" to open POSIX file */path/to/somefilename*。看起来我可能想要使用OSACompileExecute，但我无法找到如何使用它的示例。我一直在寻找如何使用OSACompile终端命令的示例。有人可以提供示例或示例链接吗？

Answer 1

好的，诀窍是不打算尝试编译和执行Applescript，而只是使用osascript系统命令：

    sprintf(cmd, "osascript -e 'tell app \"Finder\" to open POSIX file \"%s/%s\"'", getcwd(path, MAXPATHLEN), file);
    system(cmd);

path和file都是char []变量。

我从 Applescript：The Definitive Guide 中获得了this excerpt的线索。

以下是使用AppleScript从Finder读取Get Info注释的示例C函数。

您可以根据需要修改它。

NSString * readFinderCommentsForFile(NSString * theFile){
/* Need to use AppleScript to read or write Finder Get Info Comments */

/* Convert POSIX file path to hfs path */
NSURL * urlWithPOSIXPath = [NSURL fileURLWithPath:theFile];
NSString * hfsStylePathString = 
(__bridge_transfer NSString    *)CFURLCopyFileSystemPath((__bridge CFURLRef)  urlWithPOSIXPath, kCFURLHFSPathStyle);

/* Build an AppleScript string */
NSString *appleScriptString = @"tell application \"Finder\"\r get comment of file ";
appleScriptString = [appleScriptString stringByAppendingString:@"\""];
appleScriptString = [appleScriptString stringByAppendingString:hfsStylePathString];
appleScriptString = [appleScriptString stringByAppendingString:@"\""];
appleScriptString = [appleScriptString stringByAppendingString:@"\r end tell\r"];


NSString *finderComment;

NSAppleScript *theScript = [[NSAppleScript alloc] initWithSource:appleScriptString];

NSDictionary *theError = nil;
finderComment = [[theScript executeAndReturnError: &theError] stringValue];
NSLog(@"Finder comment is %@.\n", finderComment);


return finderComment;

如何从C ++程序执行简单的Applescript？
