Counting Lines in a MS VC++ 6.0 project

Sample Image - LineCounter.gif

Introduction

Ever wondered how many lines a project you have worked on for a month (or maybe for a year!)? Well, we did this for you :)

This program (LineCounter) was developed with one purpose only: to count your lines!

The program is able to count source code, comments (both styles: "// comment" and "/* comment */"), and blank lines. It shows the results in a couple of editboxes, and has a preview window (right click on the list).

The program opens the project file (.dsp) and throws it through the parsing code. After parsing is done the list of project files is steped-by-step and lines are counted.

That's it! The source code is pretty self explanatory, so I guess you'll manage.

**********************************************

Also the way the percentage of comments to total lines is kind of irrelevant. Its more useful to
measure % comments to # of source lines.

But this was real useful to me to get a quick handle on a project I work on and create a spreadsheet from the results.

Thanks

this is definitely a useful tool, and...

it will be convenient to merge all the source file into one file for printing or what ever. MS never provide a way so that I can print whole project in one "pushing" good job! so 5 pt from here

Actually Visual Studio 6 does at least provide a way for you to print all open documents. It is one of the sample Macros. I am sure that with a little tweaking you can edit the macro such that it does not require the documents to be open in order to print (i.e. it will open them to print, then close them.

your program is not counting lines correctly

Ok so I just wrote a simple FTP server and I wanted to know how much lines I used.
Anyway, it seems that your program doesn't count lines for all C++ styles. A file with 664 lines returned 0 lines in every fields. thats not normal.
The files that were counted incorrectly were not written by me, but they do compile.

Oh and I don't like your user interface. The menu's are simply not useful and there shouldnt be any Count item. simply count the lines on file open. Its just a waste of time for the poor user.
oh well.

heres a sample of my stack.cpp (which returns 0 lines, I can guarantee that its wrong):



#include "stack.h"

 

int StackNotEmpty(stk_stack * theStack) {

  return( theStack ? (int) theStack->top : 0);

}

 

stk_stack * StackJoin(stk_stack * stack1, stk_stack * stack2) {

  if (!stack1->tail) {

    free(stack1);

    return(stack2);

  } else {

    stack1->tail->next=stack2->top;

    stack1->tail=stack2->tail;

    free(stack2);

    return(stack1);

  }

}

why?

why don't you count lines in .rc files?

Well, I find the project interesting, and since i've never put a contribution of mine on the web site, i should not be allowed to write what follows, but : the code itself is really .... ugly . Maybe that's why this article is not in the programming sample. However, this works, and that's the point, i think ~RaGE();
