Hi,

The IntelliJ D Language plugin has support for D-scanner and DCD. Both tools needs to know the paths to druntime/import and Phobos source folder.
In IntelliJ you set the path to the folder where dmd binary is located. Based on this information on Windows and MacOS it is possible to determine the paths.

The code can be found here
https://github.com/intellij-dlanguage/intellij-dlanguage/blob/develop/src/main/java/io/github/intellij/dlanguage/codeinsight/dcd/DCDCompletionServer.java#L180

I want to provide a fix that the paths are also automatically determined on Linux correctly but I do not have much Linux experience.

Is there a way to find out both paths based on the dmd executable folder?

What I found out so far, these paths are not always correct:
/usr/include/dmd/druntime/import
/usr/include/dmd/phobos

Kind regards
Andre

Arch Linux and derivatives keep them under /usr/include/dlang/{dmd,gdc,ldc}/*

You may have to hardcode some common paths and try them in each in turn. I'm happy to be proven wrong here though.

Somehow also the DMD executable needs to know which Phobos/DRuntime it should use.
How does DMD is working here? Maybe I can do the same...

Kind regards

DMD determines default import and library paths from the dmd.conf file typically at /etc/dmd.conf.

Maybe this helps?

DMD: https://github.com/dlang/dmd/blob/master/src/dmd/dinifile.d#L40
LDC: https://wiki.dlang.org/Using_LDC, https://github.com/dlang/dmd/blob/master/src/dmd/frontend.d#L97

Once you have the config file, simply parse the config files: https://github.com/dlang/dmd/blob/master/src/dmd/frontend.d#L156

Anyhow as DMD is on DUB, there's no need for copy/pasting:

---
#!/usr/bin/env dub
/+dub.sdl:
dependency "dmd" version="~master"
+/
void main()
{
    import dmd.frontend;
    import std.stdio;
    findImportPaths().writeln; // will determine the currently active "dmd" compiler (can be LDC too)
}
---

DMD's order is a bit annoying, see: https://github.com/dlang/dmd/pull/7915

Thank you all for the answers. That was exactly the answers I searched for.
The IntelliJ D plugin is written in java/Kotlin so I cannot use dmd here but simple rewrite the logic in java.

Kind regards
