 |
|
I'd like to know how I go about converting/copying the contents of const(char)[] to a string.
I have an associative array that's being looped though and on each loop I want to take the key and use it in a string replacement to swap out a tag in a string.
Here is what I'd like to do:
| Code: |
foreach (const(char)[] key, string value; this.pairs) {
writeln(key);
writeln(value);
writeln(replace(this.tpl, key, value));
}
|
It throws the error

SwapElements.d(36): Error: cannot implicitly convert expression (key) of type const(char)[] to invariant(char)[]
|
According to the manul replace requires a string, so I'd like to convert const(char)[] to a string so I can use this function.
I'll even accepts an ugly solution like looping through the individual characters and appending them to a string as it'll make swapping out tags more elegant.
Thanks. |

SOlution:
I changed string[char[]] pairs; to string[string] pairs; I can now use the key value directly. |

You could also use the property to create an invariant duplicate. For your case, though, I think you've found the "right way."

| Thanks for the reply, I'll keep that in mind if I run into a similar situation. |
