rdmd

Synopsis

In a command prompt:
% cat myprog.d
import std.stdio;
void main()
{
    writeln("Hello, world without explicit compilations!");
}
% rdmd myprog
Hello, world without explicit compilations!
% _
Inside a D program:
% cat myprog.d
#!/usr/bin/env rdmd
import std.stdio;
void main()
{
    writeln("Hello, world with automated script running!");
}
% ./myprog.d
Hello, world with automated script running!
% _
(Under Windows replace cat with type and #!/usr/bin/env rdmd with #!rdmd, the latter assuming that rdmd can be found in your path.)

Description

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.

Usage

rdmd [dmd and rdmd options] progfile[.d] [program arguments]

In addition to dmd's options, rdmd recognizes the following:

--build-only
just build the executable, don't run it
--chatty
write dmd commands to stdout before executing them
--compiler=/path/to/compiler
use the specified compiler (e.g. gdmd) instead of dmd
--dry-run
do not compile, just show what commands would be run (implies --chatty)
--eval=code
evaluate code including it in void main(char[][] args) { ... } (multiple --eval allowed, will be evaluated in turn)
--exclude=package
exclude a package from the build (multiple --exclude allowed)
--force
force a rebuild even if apparently not necessary
--help
show a help message and exit
--loop=code
like --eval, but code will be additionally included in a loop foreach (line; stdin.byLine()) { ... }
--main
add an empty void main() {} function (useful for running unittests)
--makedepend
print dependencies in makefile format and exit
--man
open web browser on manual page
--shebang
rdmd is in a shebang line (put as first argument)
