rdmd is a companion to the dmd compiler that simplifies the
typical edit-compile-link-run or edit-make-run cycle to a
rapid edit-run cycle. Like make and other tools, rdmd uses the
relative dates of the files involved to minimize the amount of
work necessary. Unlike make, rdmd tracks dependencies and
freshness without requiring additional information from the
user.

I have a simple standard .d script and I'm getting annoyed that
it takes 2-3 seconds to run and see the results via rdmd.
This might sound like insanely laughable time to be annoyed by,
but it is a enough of a problem for me to make a Thread in a D
lang Forum.
Every time I make a change to a script it takes at least 2
seconds on my computer for it to run, if you are beginner like
me - you know it is not very pleasant to wait out that
duration. I wonder if anything can be done about it, why it
takes so "much" time, and why can't the results show up in a
few milliseconds instead?
#!/usr/bin/env rdmd
import std.stdio, std.process;
void main() {
writeln("This writeln is taking long time ");
executeShell("pause");
}
If I remember correctly:
rdmd does one step in the compilation step twice and is therefore
slower than dmd.
Dmd was in the meantime enhanced to provide the same
functionality as rdmd.
I assume dmd -i -run myscript.d
If you have one file only, you do not need the -i argument.
Also please keep in mind there could be other factors like slow
disks, anti virus scanners,... which causes a slow down.
Dmd also allows you to just test the syntax of your source code
file without generating an executable.
Kind regards
