cpp_toolbelt

Collection of useful C++ classes and utility functions

I find these useful when writing C++ code.

The classes are:

1. FileDescriptor: a reference counted UNIX file descriptor representing an open file
2. InetAddress: an interet address (IPv4 for now)
3. Socket: a general socket
4. UnixSocket: a UNIX Domain socket
5. TCPSocket: a TCP socket
6. UDPSocket: a UDP socket
7. Logger: a level-aware logger that prints in color on TTYs
8. MutexLock: an RAII class for handling pthread mutexes
9. BitSet: a fixed size set of bits that allows allocation.

In addition, the following functions are provided:

1. Hexdump: dump memory in hex
2. Now: get the current nanosecond monotonic time.

The Socket classes are coroutine aware and need my coroutine library

Enjoy!

Downloading and using the toolbelt

Add this to your WORKSPACE file to download and use toolbelt:

http_archive(
  name = "toolbelt",
  urls = ["https://github.com/dallison/cpp_toolbelt/archive/refs/tags/A.B.C.tar.gz"],
  strip_prefix = "cpp_toolbelt-A.B.C",
)

Replacing A.B.C with the version you want (e.g. 1.0.3).

Add a dependency to your BUILD.bazel targets like this:

  deps = [
      # ...
      "@toolbelt//toolbelt",
  ],

All the header files are in toolbelt/, so for example:

#include "toolbelt/fd.h

Then you can use it as:

toolbelt::FileDescriptor fd_;
