Hello,

decided I'd post about my primarily D-influenced programming 
language here.

It's data oriented, compact and despite D's influence, has a very 
different personality with no emphasis on metaprogramming – 
albeit having simple polymorphism and even compile time 
execution. Stability is something I care about deeply so you can 
expect few to no deprecations over time after some initial 
instability perhaps.

Feature set is not large and I'm not willing to add a whole lot 
of "cool" convenience features besides what there already is, and 
there is no support for either OO or functional style 
programming.  However, I'm rather open to adding features that 
unlock great performance benefits, such as intrinsics support.

The module system is similar to Rust and works nicely with 
conditional compilation in that you can exclude entire modules 
and directories and, unlike in Rust, use conditional symbols that 
are automatically visible to all submodules.

The compiler frontend is about 34k lines of code, self hosting 
and very fast.  LLVM is the backend, but with the MIR used in the 
compiler, it's fairly straight forward to bolt on other backends.

Compiler source code:
https://github.com/tjhann/gordon

Website:

I don't know how to make websites... and I want a much lighter 
background actually.

Take a look!  :)

Support for LLVM intrinsics should be indeed of a great value 
added.
That could work by adding a new attribute with a string exp to 
recognize it.
without that the oprations that are done in the FPU can only be 
based on assembly and less inlinable.

Congrats for reaching self-hosting.

Once thing I notice is that there does not seem to be a way to 
generate debug info. You really should support them (LLVM C api 
has a whole header with everything you need to achieve that), 
because not only this allows to debug the compiler more easily 
but also can be used to easily instrument code in a generic way. 
With debug info, you can of course debug but also profile 
(valgrind --tool=calgrind), find leaks (valgrind), cover (kcov), 
etc.

Oh yeah, this. Needs to happen, yes. I'm not much of a debugger 
guy myself having never used a debugger in my entire life so that 
side would be just for others but the other benefits attract me 
too. Thanks for bringing them up.

Thanks for creating D, Walter. I liked the core D language the 
moment I first saw it and got immediately sucked in. Also wrote 
my boot compiler in it :)

Ah, didn't know about that although have heard the name somewhere.

I actually named my language after Gordon Freeman from the 
Half-Life games which I liked to play. He gets lots done with 
little resources and is silent. My favorite game character.

I was hoping the language is inspired after Gordon Ramsay. With 
compile errors like:

"Look at these pointers, they're RAW",
"This syntax is disgusting"
"The code is not good enough!"

And just so people could still successfully build their projects 
that day, a compiler switch would appear, "-disable-ramsay".

I wanted to have a language that accurately supports my way of 
doing programming and doesn't have many features beyond that, a 
lean language.

I wanted more clarity and stability and a more Rust like module 
system and a different conditional compilation system. I 
absolutely love how those work together in Gordon.

As a nice overall kind of bonus, I could do numerous little 
tweaks and changes with full freedom. Like the opposite of a 
death by a thousand paper cuts.

I could revamp the compiler interface too, not that I ever had 
gripes with dmd's.

And you know this was my dream, it was in me, I had to let it 
out! :)

I'm not sure what you mean, there is no D-interop. It's just a 
similar language so by tweaks etc I mean differences to D.

Ok, I didn't look at it. Just thought it was a derivative of D,

Haven't done html in years, but I believe this line is specifying 
the color of your text and the color of your background:

->  body { font-family: monospace; color: #e0e0da; 


The values in main.css are for a dark text on a light background: 
background: #F0EDE3;


You could either remove the "{body.." line from index.html or 
modify the "color" and "background-color" attribute values.

```d
  1 // The default enum base type is ubyte to not bloat structs 
(better for cache use).
  2 enum MODE : int {
  3     FAST,
  4     DEEP,
  5     ADAPTIVE,
  6 }
  7
  8 int main()
  9 {
10     auto m = MODE.DEEP;
11
12     // A switch on enum must be exhaustive of course.
13     switch (m) {
14         case MODE.FAST:
15             break;  // empty case falls through by default – 
use break to avoid
16         case MODE.DEEP:
17             int a = 1234;
18             goto;   // fall through
19         case MODE.ADAPTIVE:
20             // do something
21     }
22
23     return 0;
24 }
```
Where does "goto ..." branch to in [example 
code](https://tjhann.github.io/gordon-web/ex2.html) above, line 
18? In D, it can be an external identifier: ```22 EXTERNAL:``` // 
from switch...

Does Gordon have it? Also isn't there a scope hierarchy, line 17?

Because a defined inside scope cannot be accessed from outside 
scope.

Finally, we use ```final switch``` in D, if there is no 
```default```.

I wish you accomplish everything...
