digitalmars.D.learn - Problem with rdmd

OTOH:

$cp htest htest.d
$./htest.d
hello world!

It seems that rdmd expects the script to bear the .d extension. 
This is not a very good choice, at least when writing git helper 
scripts.

For example, a "$git command" command would eventually try to 
execute the executable (script):

$git-command

The problem is that that line expects git-command, not 
git-command.d.

A workaround for this?

Thanks

yup

I'm pretty sure it's DMD that is the problem.

Yes. But that's, the least to say, limiting.

This:

https://github.com/D-Programming-Language/tools/blob/master/rdmd.d#L160

should be solved in other manner. Maybe creating a temporary 
copy. Or forcing dmd in some ways. Besides, for what reasons dmd 
would impose a .d extension?

This is an ancient dmd misfeature - it treats `dmd test` as `dmd 
test.d`, adding .d silently. No idea if someone actually wants 
this behavior..

One possible solution would be for rdmd to create a link in its 
temporary directory to the original file. (The link would have a .d 
extension.)

Isn't more reasonable to change dmd's behavior?

Why don't just compile it manually once instead of using like a script?

Bah, what would be the meaning of accepting the shebang syntax 
then? SCripts are made to provide a quick way to hack: you edit 
it for 5 mins, you run it. You change a parameter inside, you run 
it. Otherwise, there would be no need for scripts, everything 
could be compiled, even if you fill everything with system() 
statements.
