Is there any other way to do a simple user input into integer
variables without using std.conv?

Is there a fast way to get a number out of a text input?
Like getting '1.5' out of 'sdaz1.5;['.
Here's what I have at the moment:
string processValue(string s) {
string ns;
foreach(c; s) {
import std.stdio;
I am somewhat new to D, and I am trying to receive user input,
like this, with a prompt:
string str;
writeln("Enter a string: ");
str = readln;
writeln(str);
However, the prompt appears after I enter the input; any reason
why?
I've trawled the internet
Hy, i'm new @ D and i come from python.
Sorry for my engish, i understand good, but i write like a cow

I make a little programm to add human's name and age and a
function to write out alls humans in the list.

Thanks guys. I did think of regex, but I don't know how to learn
it.

hmm the paste is away ?!? here i post my source one more time.
[code]
import std.stdio;
import std.string;
struct Human {
string name;
ushort age;
};
void print_human_list(Human[] human_list){
foreach(human; human_list){
writeln(human.name);
writeln(human.age);

The problem is, it writes instant "Name: Age:" at the standart output.
readf reads the element from the stream, and NOTHING MORE, it leaves the
newline on the stream.
So the next readf then reads the newline as a string. You can fix this
by using readf(" %s"
The paste is still there.
readf leaves the \n from pressing enter in stdin, which gets read
by the next function that's accessing it.
I answered a similiar question in another thread:

I see two other mistakes in your code as well:

It also works:
-
import std.conv;
import std.stdio;
import std.string;
struct Human {
string name;
ushort age;
}
void print_human_list(Human[] human_list) {
foreach(human; human_list) {

Hi,
Is there a way to transform user input string to a regular
expression? For example, I want to write a `grep`-like program
```
mygrep -E '/pattern/i' file.txt
```
and here the user's parameter `/pattern/i` would be converted to
a Regex object.
Fyi, in Ruby, `to_regexp`

Wondering if this is possible? Ask a user at input and wait for
response:
write("Is the sky blue? ");
readf!" %s\n"(response);
If the user's response is correct, I'd like to change the color
of provided response to indicate it was correct then advance to
the next line and ask a different ques

You need to use a terminal-control library, such as
`arsd.terminal`

I have no experience with Gtkd but the code inside main looks
fundamentally wrong. One would expect you to do something with the
