stdin

The standard input stream.

alias stdin = makeGlobal!(StdFileHandle.stdin)

Return Value

stdin as a File.

Note: The returned File wraps core.stdc.stdio.stdin, and is therefore thread global. Reassigning stdin to a different File must be done in a single-threaded or locked context in order to avoid race conditions.

All reading from stdin automatically locks the file globally, and will cause all other threads calling read to wait until the lock is released.

Examples

1 // Read stdin, sort lines, write to stdout
2 import std.algorithm.mutation : copy;
3 import std.algorithm.sorting : sort;
4 import std.array : array;
5 import std.typecons : Yes;
6 
7 void main()
8 {
9     stdin                       // read from stdin
10     .byLineCopy(Yes.keepTerminator) // copying each line
11     .array()                    // convert to array of lines
12     .sort()                     // sort the lines
13     .copy(                      // copy output of .sort to an OutputRange
14         stdout.lockingTextWriter()); // the OutputRange
15 }
