从 XCode 4.2 外部跳转到文件和行

对于 NSLogger 项目，我们希望实现直接跳回 XCode 到发出日志条目的文件中的行的功能。人们会期望使用这样的命令行工具很容易做到这一点：

xed --line 100 ~/work/xyz/MainWindowController.m

但这会导致意外错误：

2011-10-31 17:37:36.159 xed[53507:707] 错误：错误 Domain=NSOSStatusErrorDomain Code=-1728“该操作无法完全的。（OSStatus 错误 -1728。）”（例如：说明符要求第 3 个，但只有 2 个。基本上，这表示运行时分辨率错误。 ) UserInfo=0x40043dc20 {ErrorNumber=-1728, ErrorOffendingObject=}

另一个想法是使用 AppleScript 告诉 XCode 执行所需的步骤，但我无法找到可行的解决方案。

因此，任何能够达到预期效果的解决方案都将非常感激。

For the NSLogger project we would like to implement the feature to directly jump back to XCode to the line in the file that issued the log entry. One would expect thatthis would be easy using the command line tool like this:

xed --line 100 ~/work/xyz/MainWindowController.m

But this results in an unexpected error:

2011-10-31 17:37:36.159 xed[53507:707] Error: Error
Domain=NSOSStatusErrorDomain Code=-1728 "The operation couldn’t be
completed. (OSStatus error -1728.)" (e.g.,: specifier asked for the
3rd, but there are only 2. Basically, this indicates a run-time
resolution error. ) UserInfo=0x40043dc20 {ErrorNumber=-1728,
ErrorOffendingObject=}

Another idea is to use AppleScript to tell XCode to do the desired steps, but I was not able to find a working solution.

So any solution to reach the desired effect would be very appreciated.

xed 工具似乎工作正常：

xed --line 100 /Users/Anne/Desktop/Test/TestAppDelegate.m

错误

例如：说明符要求第 3 个，但只有 2 个

上面的错误只是表明请求的行超出范围。

解决方案

在执行xed之前检查行号是否确实存在。

快速编写的示例

// Define file and line number
NSString *filePath = @"/Users/Anne/Desktop/Test/TestAppDelegate.m"; 
int theLine = 100;

// Count lines in file
NSString *fileContent = [[NSString alloc] initWithContentsOfFile: filePath];
unsigned numberOfLines, index, stringLength = [fileContent length];
for (index = 0, numberOfLines = 0; index < stringLength; numberOfLines++)
    index = NSMaxRange([fileContent lineRangeForRange:NSMakeRange(index, 0)]);

// The requested line does not exist
if (theLine > numberOfLines) {
    NSLog(@"Error: The requested line is out of range.");

// The requested line exists
} else {

    // Run xed through AppleScript or NSTask
    NSString *theSource = [NSString stringWithFormat: @"do shell script \"xed --line %d \" & quoted form of \"%@\"", theLine, filePath];        
    NSAppleScript *theScript = [[NSAppleScript alloc] initWithSource:theSource];
    [theScript executeAndReturnError:nil];

}

注意

确保正确计算行数：

The xed tool seems to be working fine:

xed --line 100 /Users/Anne/Desktop/Test/TestAppDelegate.m

Error

e.g.,: specifier asked for the 3rd, but there are only 2

The error above simply indicates that the requested line is out of range.

Solution

Check wether the line number actually exists before executing xed.

Quickly written example

// Define file and line number
NSString *filePath = @"/Users/Anne/Desktop/Test/TestAppDelegate.m"; 
int theLine = 100;

// Count lines in file
NSString *fileContent = [[NSString alloc] initWithContentsOfFile: filePath];
unsigned numberOfLines, index, stringLength = [fileContent length];
for (index = 0, numberOfLines = 0; index < stringLength; numberOfLines++)
    index = NSMaxRange([fileContent lineRangeForRange:NSMakeRange(index, 0)]);

// The requested line does not exist
if (theLine > numberOfLines) {
    NSLog(@"Error: The requested line is out of range.");

// The requested line exists
} else {

    // Run xed through AppleScript or NSTask
    NSString *theSource = [NSString stringWithFormat: @"do shell script \"xed --line %d \" & quoted form of \"%@\"", theLine, filePath];        
    NSAppleScript *theScript = [[NSAppleScript alloc] initWithSource:theSource];
    [theScript executeAndReturnError:nil];

}

Note

Make sure to count the number of lines correctly:
