|
|
* stringtok.h -- Breaks a string into tokens. This is an example for lib3.
|
|
*
|
|
* Template function looks like this:
|
|
*
|
|
* template <typename Container>
|
|
* void stringtok (Container &l,
|
|
* string const &s,
|
|
* char const * const ws = " \t\n");
|
|
*
|
|
* A nondestructive version of strtok() that handles its own memory and can
|
|
* be broken up by any character(s). Does all the work at once rather than
|
|
* in an invocation loop like strtok() requires.
|
|
*
|
|
* Container is any type that supports push_back(a_string), although using
|
|
* list<string> and deque<string> are indicated due to their O(1) push_back.
|
|
* (I prefer deque<> because op[]/at() is available as well.) The first
|
|
* parameter references an existing Container.
|
|
*
|
|
* s is the string to be tokenized. From the parameter declaration, it can
|
|
* be seen that s is not affected. Since references-to-const may refer to
|
|
* temporaries, you could use stringtok(some_container, readline("")) when
|
|
* using the GNU readline library.
|
|
*
|
|
* The final parameter is an array of characters that serve as whitespace.
|
|
* Whitespace characters default to one or more of tab, space, and newline,
|
|
* in any combination.
|
|
*
|
|
* 'l' need not be empty on entry. On return, 'l' will have the token
|
|
* strings appended.
|
|
*
|
|
*
|
|
* [Example:
|
|
* list<string> ls;
|
|
* stringtok (ls, " this \t is\t\n a test ");
|
|
* for (list<string>::const_iterator i = ls.begin();
|
|
* i != ls.end(); ++i)
|
|
* {
|
|
* cerr << ':' << (*i) << ":\n";
|
|
* }
|
|
*
|
|
* would print
|
|
* :this:
|
|
* :is:
|
|
* :a:
|
|
* :test:
|
|
* -end example]
