digitalmars.D - Generating .di header files from ImportC files

reply Walter Bright <newshound2 digitalmars.com> writes:
Bruce and Adam and I met at a Red Robin in Seattle to chat about D, and they 
both made a case for the D compiler being able to translate C files into .di 
"header" files.

The idea is to:

1. be able to work with D IDE programs that can only deal with D code

2. be able to handle the vast bulk of converting .h to D code, and then tweak
by 
hand the bits that didn't translate well

Anyhow, I pontificated that this couldn't be done, because some C code is not 
representable as D code. Silly me.

But I got to thinking about it. It turns out that DMD can currently do this:

     dmd -c test.c -Hf=test.di

and voila! It creates a .di file from the C file. Who knew?

It could use some adjustment, but the bulk is there and it didn't crash or 
launch nuclear missiles. (Phew!)

Just like I discovered that ImportC could successfully import and use D code 
(including templates!), this is another fine discovery that DMD can convert C 
code to D code! An unexpected feature that (nearly) comes for free!

Wow!

Anyhow, have fun experimenting with this!

Interesting indeed. Nice work.

Can you expand on how dmd can convert C to D? I didn't quite get 
that part.

DMD already has the capability to read in a .d file, then from the AST generate 
a .di file. Since ImportC gets turned into an AST, too, it can turn that AST 
into a .di file, too.

Nice, I just tried it and as long as you have your path setup 
right, it works well :)

For others reading this, since I'm on Windows, I just opened the 
developer command prompt and just ran:

dmd -c hashmap.c -Hf="hashmap.di"

And it just worked. Pretty impressive.

You probably did! :-)  I knew that others had it brewing for a 
bit but had not remembered it as being *that* old!  Kudos.

Anyway, glad to see this is being explored/exposed.  It's great 
to draft along behind the, well maintained, importC capability.

If anybody else is in the area on the third Wednesday of the 
month we usually meetup at the NWCPP talk and then head out 
somewhere afterwards to chat. Usually D, sometimes not. If you 
want more details you can DM me on Discord.


 The idea is to:

 1. be able to work with D IDE programs that can only deal with 
 D code

 2. be able to handle the vast bulk of converting .h to D code, 
 and then tweak by hand the bits that didn't translate well


3. Can be useful for debugging calls to ImportC methods so you 
can see where you messed up at the call site.


 Anyhow, I pontificated that this couldn't be done, because some 
 C code is not representable as D code. Silly me.

 But I got to thinking about it. It turns out that DMD can 
 currently do this:

     dmd -c test.c -Hf=test.di

 and voila! It creates a .di file from the C file. Who knew?


This is pretty much how I stumbled on to it at DConf this year. I 
briefly started with a hand translation of the ODBC 4 headers, 
got bored, then Nick Wilson suggested I look into ImportC, and 
then I just decided to smash the -Hf onto the end to see if it 
would work. The first file I tried it on worked, so I kept going. 
Eventually I ran into an anonymous tagged enum that D doesn't 
support, but the trick was to just comment it out and retry.

D simply doesn't support every C semantic, and that's OK, it's 
not supposed to, so where it doesn't, some better error messages 
are all we need to make this system more accessible. But it 
works! One place I can see something like this being popular is 
building DUB-based Code-D enabled (VSCode and others) bindings 
for non-source-available C libraries. There is a universe of C 
libraries waiting for us to generate bindings and bring them to D.

And if you miss DConf, you're really missing out. The 
interactions are top-shelf, and even if you don't learn anything 
from the talks (but you will), the discussions you have with the 
attendees more than make up the price of admission.


 It could use some adjustment, but the bulk is there and it 
 didn't crash or launch nuclear missiles. (Phew!)


Some helpful adjustments (if possible):
- Ability to set an explicit module name for the DI file. (Useful 
for creating properly namespaced bindings for libraries like 
ODBC.)
- One module per header file. For example, in the ODBC headers, 
they all reference a common header for types. If D could follow 
that on the output side we wouldn't have undo the duplicated 
types by hand. Don't know if it's possible, but it'd be a serious 
time saver.

Mix all that together and there are some significant gains to 
made to the language's  capabilities just by importing C 
libraries. I love it!

What's the status of your ODBC 4 work? Is it something you plan 
on creating a dub package for? Potentially it could be worth 
putting the changes into the current [odbc 
package](https://code.dlang.org/packages/odbc) (copied from 
_etc.c.odbc.*_ so that it can be used in DDBC & HibernateD) which 
is v3 only.

I am currently awaiting a couple of bug-fixes to ImportC, but 
I've been using my local hacked up version of the ODBC4 headers 

for inclusion in Phobos, so I can confirm that the ImportC 
version of the MSFT standard headers work, with workarounds. 
(Repo here: https://github.com/microsoft/ODBC-Specification/)

As for where it will end up. I've already received support for 
merging ODBC4 into etc.c.odbc, which is why those packages are 
rescued from deprecation in 2.106 and fixed up to enable working 
on non-Windows platforms. And merging it into etc.c.odbc makes it 
easier to get my Recordset code included in Phobos.

DConf this year was good for SQL/DB folks.

Wait, _etc.c.odbc_ is no longer being removed? That's good to

Correct. I was able to rescue it at DConf and patched it up to 
work on non-Windows systems.

No major announcement, just an entry in in the changelog: 
https://dlang.org/changelog/pending.html#PR8804

I didn't think it worthy of a forum announcement or anything, 
although that may be blindness on my part as I talked to a bunch 
of people at DConf about it and most seemed OK with it, so I just 
went ahead and did it.

Reading the thread you linked it seems that people raised the 
same issues I did. Interesting. It appears that nobody realized 
that the MinGW versions, aside from being ancient, were also 
version(Windows), which is just hysterically wrong. They should 
never have been in DRT to begin with.

Don't hurt me, but would the solution I present in this bug work?

It would be nice if the Intellij plugin could do this by 
right-clicking on a c file. I've created a github issue for it:

Great hidden feature!

I just tried this out for converting the libsodium headers into a 
.di file. It requires a little work before turning it into a .di 
(e.g. removing extensions) and then a little bit after (since the 
compiler generates code like `void someFunc(const struct 
someStruct* param1)`.

But after a few seds and a small D script to remove declarations 
I don't care about, it actually wasn't too painful compared to 
using something like dstep which is a 50/50 gamble on whether it 
works, and is a much bigger pain to automatically clean the 
output of.
