Off-the-Shelf C++ Hex Dump Code

跟風遠走 提交于 2020-01-27 06:16:12
问题 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

Create Binary files in UNIX

时光毁灭记忆、已成空白 提交于 2019-12-31 22:22:07
问题 This question was out there for a while and I thought I should offer some bonus points if I can get it to work. What did I do… Recently at work, I wrote a parser that would convert a binary file in a readable format. Binary file isn't an Ascii file with 10101010 characters. It has been encoded in binary. So if I do a cat on the file, I get the following - [jaypal~/Temp/GTP]$ cat T20111017153052.NEW ==?sGTP?ղ?N????W????&Xx1?T?&Xx1?; ?d@#e? ?0H????????|?X?@@(?ղ??VtPOC01 cceE??k@9??W傇??R?K?i2??d

问题 I have a column of data in a SQLite table being stored as a blob. Specifically, it is a serialized POJO (java object).

Write different hex-values in Python2 and Python3

大憨熊 提交于 2019-12-20 03:55:17
问题 I'm currently porting a Python2 script to Python3 and have problems with this line: print('\xfe') When I run it with Python2 python test.py > test.out , than the file consists of the hex-values FE 0A , like expected. But when I run it with Python3 python3 test.py > test.out , the file consists of the hex-values C3 BE 0A . What's going wrong here? How can I receive the desired output FE 0A with Python3. 回答1: The byte-sequence C3 BE is the UTF-8 encoded representation of the character U+00FE.

Convert a binary string to Hexadecimal and vice-versa in Elixir

老子叫甜甜 提交于 2019-12-19 05:20:34
问题 How do you convert a binary string to a Hexadecimal String and vice-versa in Elixir? There are a few posts on SO regarding this topic for other "main stream" languages. There's even an SO post that benchmarks various C# implementations How do we do this in elixir? My implementation was too ugly to share... :( 回答1: There is Base.encode16/2: iex(1)> Base.encode16("foo") "666F6F" You can also specify the case: iex(2)> Base.encode16("foo", case: :lower) "666f6f" 来源: https://stackoverflow.com
