hey Xliff, you have a message: gist.github.com/5fdc4d64aae1323e56...76e45de2bd

tigerpaws Supposing I wish to convert some XS module from perl5 to raku. What is the recommended approach? 01:41
Xliff tigerpaws: NativeCall. What modules are you interested in? 01:43

tigerpaws I'm looking at interfacing tensorflow, but that needs google's protobuff. For that, I found code.google.com/archive/p/protobuf-perlxs/. I don't know how old it is, but at worst it might give me a headstart. 02:04
Xliff Looking... 02:05
02:05 Manifest0 left 02:06 Manifest0 joined
Xliff Damn. File not found. 02:06
02:07 ensamvarg_g6 joined
Xliff Found this 02:07
github.com/spiritloose/protobuf-perlxs
tigerpaws Ah. Good catch. I was about to download the source and move it manually to github. It's not so old. I was worried it might be 2008 or something. 02:09
Xliff I think the best bet is to take the XS code and convert it using NativeCall. It's not trivial, though. I tried doing this with libxml2 and it I never finished. 02:10
So it looks like this code needs to be run against something. Do you know what? 02:11
tigerpaws But what I saw of NativeCall (not actually having used it yet) it seems generally simpler than XS. Yes, the code is run against .proto files that specify the interface to google libraries, in my case, tensorflow. 02:12
The protocode is a grammar specifying the interface parameters to the different library functions. I expect to use the tensorflow C library directly, but there are a lot of functions, and they may change, since the api is not yet stable. It's safer for me to use tensorflow's .proto files so I can catch changes as they happen. 02:15
Xliff I think the best thing to do is convert this to a set of NativeCall defs: github.com/tensorflow/tensorflow/b.../c/c_api.h
Do you have examples of the .proto files?
tigerpaws yes. for example, github.com/tensorflow/tensorflow/b...ster.proto 02:17
Xliff Hmmm... I'd have to examine this more closely before I could provide you a strategy. 02:18
tigerpaws But you may be right, maybe I'm better off going directly to the C api and just using the proto files as examples.
Xliff I think so.
If you would like, I'd be happy to help you with this.
tigerpaws There are a lot of protobuf files in that directory. Yes, I would certainly appreciate some help. I'll start by cloning the tensorflow C api. The description for adding new language bindings to tensorflow is minimal, but at least they specify the minimum set of classes we need. 02:21
So I'll start with bare skeletons of all the classes, then see how to fill them in. 02:22
Xliff It's better if you don't use C++ and go straight to the C API.
But go ahead and break things down into classes and we'll touch base. You have my email, right? 02:23
tigerpaws Yes, C++ would require another level of wrappers. What's your email? 02:24
Xliff Check your PMs
tigerpaws ??
Xliff Oh. I never sent it... LOL! 02:25
I just did.
tigerpaws PM=private message? Got it. Thanks.
Let me get a skeleton going. I intend to try to interface tensorflow into raku so we can run tensorflow with native raku vector objects. I'm realtively new to raku, but have over 20 years of perl experience. Now I'd like to help raku get some traction where python runs the world. 02:28
Xliff Excellent! Sounds like a plan! 02:30
Looking forward to working with you. 02:31
tigerpaws I'm also wondering whether having Inline::J (www.jsoftware.com/#/README) might be interesting. It's faster than numpy for matrix stuff. It's an APL offshoot
Trouble is, it's not open source.
It is a C library. 02:32
Xliff Does it have header files?
tigerpaws and the source is available. It has header files.
Xliff As long as we have that, we can use it. We'll just have to be very careful with the licensing issues. 02:33
tigerpaws Those are my two project ideas. J is free for non-commercial use. For commercial use, a license is required from jsoftware.
I haven't seen any place where J has been embedded, so I don't know how it might work. I an sending them an email to find out how receptive they are to the idea, and how it might work. 02:35
Xliff Well, I assume we will start this out as non-commercial and move from there, so the initial work should be covered, yes? 02:36
However an exploratory email is as good idea.
BTW - Here are some of the projects I've been working on, if you are curious: drive.google.com/file/d/12j1Dy6zIc...sp=sharing
Think of that as a CV ... :) 02:37
tigerpaws Great. Your knowledge of spreadheets might come in handy on the data loading side... tensorflow eats data like there was no tomorrow. 02:39
As for J, I was not worried about the non-commercial side, just how much assistance they might be willing to provide (especially if we run into bugs in their library). 02:41
Xliff OK. 02:43

do we have the concept of car and cdr from lisp 06:10
?
for our lists and arrays?
or we should manipulate the arrays with tail or something similar?
guifa2 - wrote a regex for what was needed, but the Intl::Numbers look interesting - will have a look - thanks 06:14

poohman in the above example do we have an idiomatic way or a simpler way than using @a.tail(@a.elems-$cnt)?? 06:47
guifa2_ poohman: hmm... 06:51
Are you needing the elements like that, or just wanting a list of lists? 06:52
(e.g., (1..10), (2..10), (3..10), etc)
poohman list of lists I guess 06:53
want it for recursion
just like cdr in lisp 06:54
guifa2_ doesn't know lisp so .... hopefully he can help 06:56
I would do this
m: my @a = 1..10; for ^@a -> $c { .say for @a.tail(@a - $c) } 06:57

tigerpaws I've converted the tensorflow headers, but they are full of 'typedef struct TF_SessionOptions TF_SessionOptions;' and this is refused by NativeCall (after being converted by APP::GPTrixie). Isn't this just an opaque type? How do I represent that for NativeCall? 15:50
timotimo there is a difference between "struct TF_blah" and "TF_blah"
in that you can't write "TF_blah my_var" 15:51
you'd have to write "struct TF_blah my_var"
for some reason
and you get around that by creating a typedef
so whenever you write TF_blah it substitutes struct TF_blah for you
tigerpaws It's been a long time I've done any C. So how do I make NativeCall accept that? raku says: Class TF_SessionOptions has no attributes, which is illegal with the CStruct representation. 15:54
timotimo you'd want to toss out all the empty ones
though you may need to forward-declare a bunch of classes
so maybe just turn them into stubs by putting ... into the body
tigerpaws There are a lot of them. I thought they were just opaque structs, so they would still be structs, but on raku's side we would never deal with their internals. 15:55
