Common Text Transformation Library: line

Simple program that uses CTTL node objects to navigate the lines inside user input text.

// sample code: line_navigate.cpp

#include <iostream>
#include "cttl/cttl.h"

int main()
{
    using cttl::input;
    using cttl::node;
    using cttl::edge;

    // one\r\ntwo
    // 0123 4 567890
    // B  E   B  E
    // 1  1   2  2
    input<> inp( "one\r\ntwo" );
    node<> B1( new_node( inp ) );
    node<> B2( new_node( inp ) );
    node<> E1( new_node( inp ) );
    node<> E2( new_node( inp ) );

    B1.go_line_home( 1 );
    B2.go_line_home( 2 );
    E1.go_line_end( 1 );
    E2.go_line_end( 2 );

    // show results:
    std::cout
        << "line 1 ["
        << B1.offset() << '-' << E1.offset()
        << ") /" << ( B1 + E1 ).text() << '/' << std::endl;

    std::cout
        << "line 2 ["
        << B2.offset() << '-' << E2.offset()
        << ") /" << ( B2 + E2 ).text() << '/' << std::endl;

/* program output:
line 1 [0-3) /one/
line 2 [5-8) /two/
*/
    return 0;
}

line 1 [0-3) /one/
line 2 [5-8) /two/
