Ohhhh, real intresting the mode functional style!!!
Like linq!
hahah
Btw, it's work very well, thansk!!!
But, how I can insert an ',' comma to separe the decimal place ?
( the last 2 digits )
I can't find a "insert" instruction in std.string or std.array

using lambda or tamplates....
Your code is not bad. This is a bit better (untested):
void main() {
import std.stdio;
import std.conv: to;
auto lines = "oi.txt".File.byLine;
int tot = 0;
foreach (const line; lines) {
if (line[0] == '1')
tot += line[253 .. 266].to!int;
}
tot.writeln;
}
If you want to write in a mode functional style (untested)
(probably it requires the 2.066beta):
void main() {
import std.stdio, std.algorithm, std.range, std.conv;
"oi.txt"
.File
.byLine
.filter!(line => line[0] == '1')
.map!(line => line[253 .. 266].to!int)
.sum
.writeln;
}
