This tool works with common C++ compilers (such as GCC and VC 7.1) to leverage C++ constructs for scripts. It is simply beyond my grasp that one needs 'special script' languages, like Perl, in order

to do 'small' tasks.

Sample SessionsI.e., one can have this shell file, that goes over all files in a given directory and prints out the big ones:
#!/usr/bin/cpsh
path topPath = argv[1]
remove_copy_if (
directory_iterator(topPath),
directory_iterator(),
bind(less, bind(file_size,_1), 10000000L),
ostream_iterator(cout, '\n'));Using ordinary C++ (with the Boost library accessible directly, such as the 'path' type in the filesystem sub namespace)
It also comes with an interactive shell, via the '-i' option, enabling sessions as (the text following '>' is what the user types):
> vector names;
> ? sizeof names
< 20
> ? names.size()
< 0
> const char* texts[] = { 'John', 'Greg', 'Bob' };
> copy (texts, texts+3, insert_iterator(names));
> ? names.size();
< 3
> transform (names.begin(), names.end(), \
>> bind(substr, _1, 1), \
>> ostream_iterator(cout, ' '));
{ohn reg ob } This is perfect for learning the language or verifying one's knowledge about complicated constructs.
So, why learn a new scripting language when all the power you need is available in C++, at least as succinctly expressed as with any other language. Oh, did I forget to mention that C++ executables are a bit faster than interpreted Ruby :-) [Less]
