当然，你可以不用Windows，我之所以这样做，只是为了稍后抖个包袱而已。

...want, but here is a workaround, if you are willing to use templates:
// Foo.h
struct Foo
{
export template<class T> void Read(T it);

I want to remove double quotes from a String
...
Assuming:
var someStr = 'He said "Hello, my name is Foo"';
console.log(someStr.replace(/['"]+/g, ''));

What is the javascript filename naming convention? [closed]
...that it explicitly describes the global namespace pollution being added.
foo.js adds window.foo
foo.bar.js adds window.foo.bar

How to make node.js require absolute? (instead of relative)
...each of your internal
application modules:
node_modules/*
!node_modules/foo

Please note that you can't unignore a subdirectory, if the parent is
already ignored. So instead of ignoring node_modules, you have to
ignore every directory inside node_modules with the

How do .gitignore exclusion rules actually work?
...
/a/b/c/*
!foo
Seems to work for me (git 1.7.0.4 on Linux). The * is important as otherwise you're ignoring the directory itself (so git won't look inside) instead of the files within the directory (which allows for the exclusion).
