String splitting in the D language
d, split, string
Solution
Use `split(line.idup)`;
`split` is a template function, the return type depends on its argument. `file.byLine.front` returns a `char[]` which is also reused for performance reasons. So if you need the parts after the current loop iteration you have to do a `dup` or `idup`, whatever you need.
Problem
I am learning D and trying to split strings: ``` import std.stdio; import std.string; auto file = File(path, "r"); foreach (line; file.byLine) { string[] parts = split(line); ``` This fails to compile with: ``` Error: cannot implicitly convert expression (split(line)) of type char[][] to string[] ``` This works: ``` auto file = File(path, "r"); foreach (line; file.byLine) { char[][] parts = split(line); ``` But why do I have to use a `char[][]`? As far as I understand the documentation, it says that `split` returns a `string[]`, which I would prefer.
