    Program or Script to Add Header to .c and .h files.

    Hi... i was going to make myself a program to add headers to .c and .h files, but as i dont want to reinvent the wheel, is there such program on the intertet? As header i mean, a comment with the name of the author, version, date of creation, licesence, and so on.

    Thank you!

    Pretty much all IDEs I know of support this feature... So use an IDE, and find out for that specific IDE.

    Considering that it's a real simple task... it might be a fun little exercise to write...

    But, yes, most IDEs do support "code snippets" you can use to insert the headers at creation time.

    Hmm i was wondering .. how can i "insert" lines on the begin of a file? If i write on a file from the begin it will start overwriting what is already on the file...

    Thank you!

    You write the header to a new file, then the full contents of the .c or .h file to that new file, then rename it. Or, if you use Linux:
    Code:
    $ cat header.txt foo.c >foo.tmp && mv foo.{tmp,c}

    Open the header file
    Read it into Memory
    Open the target file
    Write the header
    Open the source file (c or h)
    read it into memory
    write it to the target file
    close files
    delete source file
    rename target file

    I was wondering if that would not make use of too much memory, but i guess there is no option. Thank you!

    Well you don't have to keep everything in memory for huge files. Just re-read the portions if you must.

    Would be a simple script in Perl or Awk. I may do something like this~ pretty good idea.

    Yep... read and write the source files as binary in 1k chunks if you like, reusing the same buffer.

    It's pretty simple in C too ....

    Remember, the forum is about C code...

    I know, but the topic creator asked for a program or script that did this. A C program isn't a script, but if you were to script it something like Perl or Awk would be nice. On the other hand a program may be in C. I haven't heard of a program that does this, but it's interesting.

    A shell script could do this too.

    True, but less portable than something like Perl at least to me. If portability wasn't a concern then shell would be the best solution I think.

    I am slowly programing here haha. Its my mother's birthday today, so no time to work. Just one advice. I am going to make a GUI for the program (i am going to try as i dont have any experince with windows forms with no Visual Studio hehe). First, how can i make the program browse the file system to find the file i want to add the header? And second, if i use some sort of scanf for the input, how can i chose the max size of the input string. I could use malloc, but i dont the size to malloc haha. I can malloc a super big size.. but that would destroy my heap...

    Hmmm maybe i am going to make use of C++.. not sure...
