It would be far more helpful if running `gdc --version` gave 
some indication of the version of D it's aligned to (which was 
2.076 last time I checked).


If you want to do this automated you can run

echo | gdc -xd -fsyntax-only -v -

see how code-d does it: 
https://github.com/Pure-D/code-d/blob/master/src/compilers.ts#L637


Then you can fetch from the output the GCC version, DMD-FE 
version and import paths using these regexes:


```js
const gdcVersionRegex = /^gcc version\s+v?(\d+(?:\.\d+)+)/gm;
const gdcFeVersionRegex = /^version\s+v?(\d+(?:\.\d+)+)/gm;
const gdcImportPathRegex = /^import path\s*\[\d+\]\s*=\s*(.+)/gm;
```

GDMD picking up wrong GDC

[WebFreak001 via D.gnu]

In GitHub Actions I installed `sudo apt install gdc-12` now 
inside Ubuntu 22.04, however `gdc` still seemed to be a small 
extra package that's symlinking gdc to gdc-11.


Now gdmd is picking up GDC 11 instead of GDC 12, causing issues 
in the build.


Is there a way to tell gdmd to use GDC 12? Right now I hacked 
around this by doing


```
sudo rm /usr/bin/gdc
sudo ln -s /usr/bin/gdc-12 /usr/bin/gdc
```

but if this wasn't a CI, I wouldn't really wanna do this.

Would it be possible to provide extra gdmd scripts like gdmd-12 
that pick gdc-12 on Ubuntu?


see commit 
https://github.com/dlang-community/libdparse/commit/03099519982c10b9d7831771bcb744f06b727400


Since this is manual DMD invocation, and not dub, I can't just 
specify gdc-12 as compiler.

I imagine what you're seeing is gdmd using the correct version 
of the compiler, just not the one you wanted.


https://github.com/D-Programming-GDC/gdmd/blob/master/dmd-script#L71-L76


I have multiple GDCs installed through apt, how do I make gdmd 
pick the higher one (`gdc-12`) and not just `gdc`?
