Support of -run and source code from stdin
May 27
Hi,
Dmd and ldc supports running source code from stdin:

```
echo 'void main(){}' | dmd -run -
```

It seems GDC does not support argument -run and I do not know wheter it supports reading source code from stdin?

Could this 2 featured be added to gdc?
This would solve the probe file issue mentioned here https://forum.dlang.org/post/uwxndbpxspwaofolksbr@forum.dlang.org

Kind regards
Andre

I see no obvious use for having something like -run in the driver. Toolchain apps are more than capable of doing this themselves.

gdc -x d -

The -x tells gcc what language to parse, as the driver is capable of handling all languages gcc knows about, eg -xc++.

Looks like the description of the problem matches what this PR is fixing.

Thanks for the info.
The issue is not about the compiled artifacts but about the probe modules (source code).
In some cases, they are not deleted (There is a module destructor in dub which should take care of).

Kind regards
