现有C ++ Hex转储代码 [英] Off-the-Shelf C++ Hex Dump Code

问题描述

我使用网络和串行通讯软件，所以我经常需要有显示或记录十六进制转储数据包的代码。

时间我这样做，我从头写另一个十六进制转储程序。我会再次这样做，但想到我会问这里：有没有任何好的免费十六进制转储代码为C + +在某个地方？

例如：

• 每行N个字节（其中N是某种可配置的）


• 可选ASCII / UTF8转储在十六进制


• 可配置缩进，每行前缀，每行后缀等。


• 最小依赖（理想情况下，
编辑：说明：我正在寻找代码，我可以轻松地进入我自己的程序写入stderr，stdout或其他这样的输出流。我不是在寻找命令行十六进制转储实用程序。

解决方案

unix工具 xxd 作为 vim 的一部分分发，并根据 http://www.vmunix.com/vim/util.html#xxd ， xxd的来源为 ftp://ftp.uni-erlangen.de： 21 / pub / utilities / etc / xxd-1.10.tar.gz 。它是用C写的，大约721行。唯一的授权信息是：

  *自由分配，并信用我，
 *赚钱和分享与我，
 *失去钱，不要问我。 
  

unix工具 hexdump a href =http://gd.tuwien.ac.at/softeng/Aegis/hexdump.html> http://gd.tuwien.ac.at/softeng/Aegis/hexdump.html 。它是用C编写的，可以从源代码编译。它比xxd有点大，并且分布在GPL下。




I work a lot with network and serial communications software, so it is often necessary for me to have code to display or log hex dumps of data packets.

Every time I do this, I write yet another hex-dump routine from scratch. I'm about to do so again, but figured I'd ask here: Is there any good free hex dump code for C++ out there somewhere?

Features I'd like:

• N bytes per line (where N is somehow configurable)
• optional ASCII/UTF8 dump alongside the hex
• configurable indentation, per-line prefixes, per-line suffixes, etc.
• minimal dependencies (ideally, I'd like the code to all be in a header file)

Edit: Clarification: I am looking for code that I can easily drop in to my own programs to write to stderr, stdout, or other such output streams. I'm not looking for a command-line hex dump utility.

解决方案

The unix tool xxd is distributed as part of vim, and according to http://www.vmunix.com/vim/util.html#xxd, the source for xxd is ftp://ftp.uni-erlangen.de:21/pub/utilities/etc/xxd-1.10.tar.gz. It was written in C and is about 721 lines. The only licensing information given for it is this:

* Distribute freely and credit me,
* make money and share with me,
* lose money and don't ask me.

The unix tool hexdump is available from http://gd.tuwien.ac.at/softeng/Aegis/hexdump.html. It was written in C and can be compiled from source. It's quite a bit bigger than xxd, and is distributed under the GPL.
