QUERY: strip trailing whitespace ... woes :S |
I am wondering about what's the best and easiest way to strip trailing
whitespace from every single file in a folder, recursively.
I want to write a program/script so that you pass in a folder name and
it'll recursively go through all sub-folders and strips trailing
whitespace from every single file.
Trailing whitespace includes:
1. whitespaces at end of text lines, strip whitespace but retain text
2. whitespaces on empty lines, strip whitespace but leave the empty
line

Define "best". Fastest? Easiest to code?
and easiest
For the programmer or for the user?

Standard C++ has no concept of "folder", "sub-folder" or even "every ...
file", so the solution is inevitably going to be platform-dependent and
off topic here. You might do better with a scripting language - for
example, perl has easy ways of applying operations to all matching
files.
Trailing whitespace includes:
1. whitespaces at end of text lines, strip whitespace but retain text
2. whitespaces on empty lines, strip whitespace but leave the empty
line
2 is just the special case of 1 when the text is of zero size. No need
to treat it specially.
std::string has lots of functions that might help - find_last_not_of,
for example.
