I've just discovered that shebang line has a (very short) limit. 
Only 127 bytes are read from line

It means that something like this doesn't work:


-I/asdasdasdasd/asdasdasdasd/asdasdasdasd 
-I/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/

Is it possible to add a command line switch to read params from a 
simple file?

For example:


main.d:

void main() { }

rdmd-params.conf:
-I/asdasdasdasd/asdasdasdasd/asdasdasdasd 
-I/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/qweqweqweqwe/

Hmmm however that's not a good solution. It would be nice if all 
what we need was embedded inside the source itself. Any idea?

I think that's a shell limitation. I've long had the plan to experiment 
with it like this: if --shebang is the first argument, rdmd should just 
read the whole first line and exec() a shell with it. That would solve a 
variety of issues related to limitations and quoting quirks.

However as I said in my second post, probably it won't solve the
problem: shebang is useful if  you can write a "self-contained"
script, something that fits inside a single file.

I agree with Andrei. It would be a good solution for my case and
it shouldn't break anything.

If you need to specify import paths, your script is probably 
fragile and broken on different linux/bsd distributions.

I don't have a solution.

It was just an example, of course. It was the easiest way to add 
some long params :)
