Re: How to use ImportC to import WebGPU header
You need to use a .c file that include it
--- webgpu.c
```c
#include "webgpu.h"
```
--- app.d
```d
import std.stdio;
import webgpu;
void main()
{
writeln(WGPUBlendFactor_Dst);
}
```
result:
```
$ dmd -run app.d webgpu.c
WGPUBlendFactor_Dst
```

How to use ImportC to import WebGPU header
I would like to use ImportC to automatically import a C header
into my D project. I've been using Dstep so far which works ok,
but requires some manual fixes to get the resulting D file to
compare and it doesn't let me to just drop the C header file.
I created a fresh dub project to try. I try to import this header
https://github.com/webgpu-native/webgpu-headers/blob/main/webgpu.h . I put webgpu.h file next to app.d.
My code is:
```
import std.stdio;
import webgpu;
void main()
{
}
```
it builds.
Then I tried to output one of the enums to see if it works:
```
import std.stdio;
import webgpu;
void main()
{
writeln(WGPUBlendFactor_Dst);
}
```
and it says:
Starting Performing "debug" build using
C:\D\dmd2\windows\bin64\dmd.exe for x86_64.

I tried to do the other commandline but I get this error instead:

They must have introduced a bug. Works for me with DMD 2.098.0
and LDC 1.28.0. ImportC is under heavy development right now.
Most of the 2.098.1 changelog was related to ImportC.

How to use ImportC?
You just add the C files like D files when you compile and import
them in your D code as you would a D module. At least that is all
I've been doing. Simple example:
foo.c:
```
double twice(double x) {
return 2.0*x;
}
```
program.d:
```
import foo;
import std.stdio;
void main() {
writeln(twice(6.8));
}
```
Compilation:
```
dmd program.d foo.c
```
