I''m looking for a utility to read through a single directory that will count the number of lines in my c/c++ source files. Anyone know where I can get one? What one is named so I can go in search of it?

I''ve never seen one, besides, it shouldn''t take more than 10-15 minutes to write your app app that can do something like that.

Thanks.

That's not what I asked for, though.

maybe my next question should be(seriously):

How do open up the directory for reading without knowing how many files are available to be read in that directory or what the names of the files are? Once I'm in the file I'm OK (I think)- I just don't know how to query for a file where I don't know it's name.

Once in the file, I what, search for text the preceeds CRLFs and count the number of CRLFs - ignoring lines that contain no text?

Oh, I'm on a winbox, btw.

Such an utility comes with Windows and is called wc.exe (wordcount), and it can count chars, words and lines.

Type

wc -l myfile.cpp

and it will tell how many lines there are in your file.

and type

wc --help

to see more options.

If you are using VS6, then Project Line Counter is free and integrates with the IDE.

Look here for information on using the FindFirstFile, FindNextFile and FindClose API functions.

Here is the code (I haven''t tested it, you would likely be best to read the docs in that link)

  
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
  
hFind = FindFirstFile("c:\documents\*.cpp", &FindFileData);
if (hFind != INVALID_HANDLE_VALUE) 
{
  CountLinesInFileCalled(FindFileData.cFileName);
  while (FindNext(hFind, FindFileData))
  {
    CountLinesInFileCalled(FindFileData.cFileName);
  }
  FindClose(hFind);
}

Note: If I remember correctly FindFileData.cFileName gives only the filename, not the complete path ("myfile.cpp" rather than "c:\documents\myfile.cpp")

Heres a small program I wrote with that method, if you want to see how it works when put together.

    
#include <fstream.h>
#include <windows.h>
#include <io.h>
#include <string.h>

void Count(char FullPath[561],int& Total,char FilePath[260]);

int main()
{
	char PathName[300];
	char FullPath[561];
	int Counter = 0;
	int Total = 0;
	cin >> PathName;

	SetCurrentDirectory(PathName); // Set directory to working one

	
	struct _finddata_t c_file; // Struct to hold data

	long hFile; // File handle

	
	if( (hFile = _findfirst( "*.cpp", &c_file )) == -1L ) // Search for a file

	{} // If not file found

	else
	{
		strcpy(FullPath,PathName);
		strcat(FullPath,"\\");
		strcat(FullPath,c_file.name);
		Count(FullPath,Total,c_file.name);
		
		while( _findnext( hFile, &c_file ) == 0 ) // keep going til no files found

		{
			strcpy(FullPath,PathName);
			strcat(FullPath,"\\");
			strcat(FullPath,c_file.name);
			Count(FullPath,Total,c_file.name);
			
		}
		_findclose( hFile ); // Close file

	}

	if( (hFile = _findfirst( "*.h", &c_file )) == -1L ) // Search for a file

	{} // If not file found

	else
	{
		strcpy(FullPath,PathName);
		strcat(FullPath,"\\");
		strcat(FullPath,c_file.name);
		Count(FullPath,Total,c_file.name);
		
		while( _findnext( hFile, &c_file ) == 0 ) // keep going til no files found

		{
			strcpy(FullPath,PathName);
			strcat(FullPath,"\\");
			strcat(FullPath,c_file.name);
			Count(FullPath,Total,c_file.name);
			
		}
		_findclose( hFile ); // Close file

	}

	cout << Total << " Lines in total\n";
	
	return 0;
}

void Count(char FullPath[561], int& Total,char FilePath[260])
{
	int Counter = 0;
	ifstream fin(FullPath);
	char ch;
	while(fin.get(ch))
	{
		if(ch == '\n')
			Counter++;
	}
	Counter++;
	fin.close();
	cout << FilePath << " has " << Counter << " Lines\n";
	Total += Counter;
}

Sorry about the comments,

You might want to consider having the options to skip whitespace lines, "{" lines and comments also.

Can someone show me this for VB? The problem with VB is the multiple different types of files, the various attributes stored in them(open em in notepad), etc.

Sure I could write a counter myself, but I''ve got better things to do.

Hey, hats off to everyone that contributed.

I''ve read portions of these two books, Programming Windows( 5th edition) and Programming Windows with MFC(2nd edition), about the windows API. I don''t recall seeing "FindFirstFile, FindNextFile and FindClose" so I''m pretty far from being an expert on the windows API.

Hmmm, let me check...Ahh, here they are! ( And for once, they''re aptly named!!

)

Thanks again.

I personally use K-LOC when I''m curious about lines of code in a project.
