My 2nd  D app in production. I and my new buddy Claude wrote  a 
log parser for MySql. Simple bread&butter program, but it was 
easy and fun to write, performant and pleasing to the eye.
There are probably a number of MySQL log parsers out there, but I 
wanted to build my own.

I found std.getopt, I like to write small things like that, 
simple useful that saves a lot of time, the problem is to find 
them when you have not written them yourself.

Before this app I tried to write a bare metal program in D 
myself, following an example I found on the net. I could not make 
it work. I asked Claude to create one, he created a working 
example after some fixing.
Claude complaint that BetterC was missing something (I forgot 
what it was) and that made it more difficult, than using C. I 
realised betterC is not a superset of C, but something else.
I also realised D bare metal is to hard for me, native assembler 
is probably a better option for me.

Somewhere I have have a Raspberry Pi4, I will try to find it, and 
write some D code there. I hope that works better than bare metal.
One question is Raspberry Pi a good 'host' for D?

Certain D libraries can be quite memory-intensive to compile.
You might want to try the `-lowmem` compiler switch.

Also, I’d recommend to look into the 8 GB or 16 GB models.
Depending on other processes (IDE, web browser, music player, …) 
on your system you might quickly run out of memory otherwise.

But that heavily depends on what you’re doing. The 4/2 GB models 
can be mighty fine platforms for D development too.

It should work with LDC

yes I used https://zyedidia.github.io/blog/posts/1-d-baremetal/. 
but I only followed 1st and last. As usual I skipped the middle 
part. Now I have redone all steps in order and now it works. I 
give the bare metal another try.
Thank you all for help and advice.

Right now I am busy with $job. The guys at the office is working 
on ending my contract, then I will have more time for D :)
