Following on my last entry, where I built a better pre-commit hook to ensure every commit in my Git history passed make check with flying colors, I realized something today about my good friend, rebase.

Recently a friend turned me onto an interesting article about a problem I had just recently discovered about Git and its pre-commit hook:

Committing in git with only some changes added to the staging area still results in an “atomic” revision that may never have existed as a working copy and may not work.

This has probably been written countless times before, but I found myself needing it today and it was quick to write. It lets you read characters from a char array in C++ via the istream interface:

#include "ptrstream.h"

int main() {
  ptristream in("Hello, world!\n");
  char buf[31];
  in.getline(buf, 32);
  std::cout << buf << std::endl;
}

Handy for if you don’t want std::istringstream needlessly copying character strings.
