Problem with 3D character array in D

Question

I am learning D, and I have a simple program that reads a text file line by line, splits each line into its own separate words, and prints it all to stdout.

import std.stdio;
import std.string;

void main(string args[])
{
    char[][][] lines;
    auto input = File(args[1], "r");
    foreach(line; input.byLine())
    {
        auto words = split(strip(line));
        lines ~= words;
    }

    foreach(line; lines)
    {
        writeln(line);
    }
}

The code to create is created words. If I just call writelnin words every time he is assigned, I get the conclusion I want. But if I add wordsin linesand output lines, something strange will happen. lineshas an entry for each line in the source file, but each line is a corrupt version of the last line. For example, if the last line of a file looks like this:

END    START        * End of routine

I get an output that looks something like this:

[       , END, ST, *, End , f rout, ne,    ,     , e other]
[     , END, ST, *, End of, rout, ne,      ,   , e othe]
[    , END, STAR, *, End of, rout, ne.,        
e]
[    , END, START  , *, End of, rout, ne.,        
e]
[END , STAR]
[     , END, START     , *, End , f , out, ne.  ]
[END, START, *, End, of ro, tine. ,  ,   ,  
]
[END, STA, *, o,  r, ut]
[  , END , S, *, End, o,  r, utine.,  ,   ,  , 
,  o]
[END, START    , *, of routi, e.,   ]

Any idea what I'm doing wrong?

Answer 1

, byLine , , .

auto words = split(strip(line).dup);

char [], . 2.0, char []. .

auto words = split(strip(line).idup);

,

import std.stdio;
import std.string;

void main(string[] args)
{
    string[][] lines;
    auto input = File(args[1], "r");
    foreach(line; input.byLine())
    {
        auto words = split(strip(line).idup);
        lines ~= words;
    }

    foreach(line; lines)
    {
        writeln(line);
    }
}

Answer 2

.

-, byLine, , ( ), .

-, words. split(strip(line)). strip ( ), , . ; , . - string[] words - , .

, , , , , auto words = split(strip(line).dup);. , words , , .

, string[] args. C- .
