blablabla. They pop out in your files time to time, cost you more times to fix them, pollute your commit history, not only that, those trailing white spaces, they are hard to spot by human eyes.
Apparently, eliminate those trailing white space is not a job suit for humans, we would better leave those tedious tasks to our friends--computer.
To teach our friend know what do I want to do, I write a small program to help us(source codes located at here), you should be able to compile and run it if you familiar with c++ and boost.
Enough of talk, let me show you an example
As you can see, Example 00 contains a lot of tabs and trailing white space, not only that, there are a tab we should not removed(tab of std::string("\t")), this is the time my small tool--kill_trailing_white_space come in. All you need to do is specify you want to remove the tab and trailing white space of a file, or the files inside the folder(will scan the folders recursively). Example
"kill_trailing_white_space --input_file main.cpp"
"kill_trailing_white_space --input_folder img_hash"
After the process, we could have a clean file as Example 01.
You can see the help menu if you enter --help.By now this small tool only support the files with extension ".hpp" and ".cpp". Feel free to modify the codes to suit your needs.
