[00:00] Christopher David: Guess who got a green screen and who doesn't know how to configure the color spill.

[00:05] Christopher David: So we're going black and white. That's okay. We'll keep leveling up. Okay, so last video was three hours.

[00:12] Christopher David: Let's not do that again for a while. Okay. But yeah, getting host functions working VR

[00:19] Christopher David: going environment and then putting it behind an L4 or two endpoint and using that in our flow. That was amazing.

[00:28] Christopher David: So

[00:30] Christopher David: Let's now go

[00:33] Christopher David: Test out the host functions of PHP. Oh, we kind of skipped over that. Just because I like the L4 or two idea

[00:40] Christopher David: but in this

[00:42] Christopher David: video we're going to use the new

[00:45] Christopher David: PHP SDK

[00:48] Christopher David: Host functions support

[00:51] Christopher David: So this is what we're using already to like load the plugins into our environment to execute them

[00:57] Christopher David: They did not until recently have host functions support. They just add to this and

[01:02] Christopher David: So we're going to try to get this working. So let's read the docs

[01:12] Christopher David: Let's see

[01:13] Christopher David: So X is in PHP host SDK

[01:18] Christopher David: This stuff we're already doing

[01:20] Christopher David: And host functions note

[01:25] Christopher David: Host function support is experimental due to usage of callback with FIFI and may leak memory. All right. Let's extend our count values example a little bit instead of storing the total in an

[01:35] Christopher David: Ephemeral plugin ver

[01:36] Christopher David: Let's store it in a persistent key value store

[01:40] Christopher David: Wazom can't use our KV store on its own. This is where host functions come in

[01:45] Christopher David: Host functions allows to grant new capabilities to our plugins from our application

[01:49] Christopher David: They are simply some go

[01:51] Christopher David: Functions. I don't think they have to be go functions

[01:55] Christopher David: Just like everyone's trying to get me to use go. That's okay

[01:58] Christopher David: We could we write which can be passed out and invoke from any language inside the plugin

[02:03] Christopher David: Let's load the manifest like usual but load up this count vowels KV store plugin

[02:09] Christopher David: Note the source code for this is here and is written in rust

[02:12] Christopher David: But it could be written in any of our PDK languages call unlike our previous plugin

[02:16] Christopher David: Express you to provide host functions that satisfy our its important interface for a KV store

[02:21] Christopher David: We want to expose two functions for a plugin void KV ranked

[02:25] Christopher David: Key string value array of bytes okay, which writes a byte value to a key and byte KV

[02:32] Christopher David: Okay, I can't think in terms of bytes. I'm just gonna trust that this is all of those what you say

[02:36] Christopher David: It's gonna do which reads the bytes blah blah blah

[02:38] Christopher David: Pretend this is red is here's the host functions

[02:41] Christopher David: Literally just like a little dummy KV store okay

[02:46] Christopher David: Bites to in blah blah blah

[02:49] Christopher David: And then we pass it cool. So the plugin provides memory pointers which the SDK automatically converts it to a string

[02:56] Christopher David: Similarly when a host function returns a string the SDK allocates it in the plugin memory and provides a pointer box of the plugin

[03:02] Christopher David: For a manual memory management request current plugin as the first parameter of the host function. I don't know

[03:11] Christopher David: Okay, and then here

[03:14] Christopher David: It's just an example that working

[03:17] Christopher David: Nice

[03:19] Christopher David: So you can manually manage the memory if you want

[03:22] Christopher David: Strain blah blah. Okay, I've separately pasted this into challenge ebt stain today

[03:29] Christopher David: We are adding host functions support to our level after this X and D

[03:33] Christopher David: Read the docs and get ready to help me implement host functions when I give you our code

[03:41] Christopher David: Okay

[03:46] Christopher David: All right, so I want to do like a

[03:51] Christopher David: Very simple. Maybe we'll get their demo code working

[03:56] Christopher David: Do we have tests like a plugin test?

[04:02] Christopher David: It has an image so that's that can execute plugin function

[04:11] Christopher David: Okay, so here's one thing I want to try if we do

[04:17] Christopher David: If we remove this from integration and

[04:21] Christopher David: We see if we open up a new one of these

[04:26] Christopher David: And we'll miss it right here

[04:28] Christopher David: If we go to the name jense now can we do pf

[04:35] Christopher David: Execute plugin

[04:38] Christopher David: Say what's that one I'm gonna say

[04:46] Christopher David: Okay

[04:51] Christopher David: And let's um

[04:53] Christopher David: Just dv it just because I want to see it. I want to see it

[05:03] Christopher David: All right

[05:05] Christopher David: So

[05:09] Christopher David: Let's do this let's copy all of this

[05:17] Christopher David: And then go back to here and say here's our unit test for plugins

[05:26] Christopher David: Note the can execute plugin function test

[05:31] Christopher David: Let's

[05:33] Christopher David: Let's write a new test that

[05:43] Christopher David: Tests that PHP host functions work

[05:47] Christopher David: Using the same count vowels

[05:51] Christopher David: Code from the

[05:54] Christopher David: Read me I paste it

[05:57] Christopher David: Use the same

[05:59] Christopher David: URL for that count vowels

[06:03] Christopher David: One when we define the plugin

[06:07] Christopher David: Together with the rest of the test that might just be enough for it to actually write us a task. Let's see

[06:15] Christopher David: Do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it do it

[06:19] Christopher David: Oh

[06:21] Christopher David: You need to ensure that your plugin model is equipped to handle instantiation. We are obviously these all pass you can see I'm passing in URL

[06:29] Christopher David: So just do it

[06:32] Christopher David: PHP host functions work with the plugin

[06:41] Christopher David: Doesn't do imports

[06:49] Christopher David: New

[06:55] Christopher David: Exitism plugin

[06:59] Christopher David: Yeah, definitely don't want all that stuff in my test file

[07:08] Christopher David: But let's put it there for now and just kind of see if it works

[07:19] Christopher David: Let's just see if it works

[07:42] Christopher David: And we don't want this to say integration oops

[07:49] Christopher David: Now

[07:56] Christopher David: Woooo it no like this oh I guess I have to update the SDK

[08:10] Christopher David: Yeah, I need update the SDK the one oh, oh, that's running

[08:19] Christopher David: How do I get it? I want it

[08:41] Christopher David: Thanks first I need to update the

[08:44] Christopher David: Exitism

[08:47] Christopher David: Exitism

[08:50] Christopher David: PDK

[08:51] Christopher David: E

[08:53] Christopher David: SDK to

[08:56] Christopher David: The latest version one point up when oh how do I do it?

[09:01] Christopher David: I'm so used to NPM commands that I like tend to accidentally run the wrong thing with composer and update everything

[09:07] Christopher David: I where I don't want to do

[09:14] Christopher David: Okay

[09:25] Christopher David: Carrot one point up let's try it

[09:28] Christopher David: Okay

[09:41] Christopher David: And update only that one

[09:43] Christopher David: Okay

[09:55] Christopher David: Okay

[10:06] Christopher David: Okay

[10:13] Christopher David: How I reload this so it stops winding

[10:25] Christopher David: Loads

[10:27] Christopher David: Oops

[10:37] Christopher David: I don't even know how to figure out what this is complaining about

[10:41] Christopher David: Wow, let's just try running it see what happens

[10:51] Christopher David: All right pf

[10:54] Christopher David: First function

[11:03] Christopher David: All right, we skipped ahead a little bit because we figured out with the Exitism team that we have to upgrade PHP to

[11:10] Christopher David: version 8.3 all right that now works this uses some the host functions thing uses some

[11:16] Christopher David: FFI dohicky

[11:18] Christopher David: You know, I use it it uses a thinging okay to use a technical term all right

[11:21] Christopher David: So we have this

[11:24] Christopher David: Test dumb demy dummy function working we're able to create a host function fine and now we're working on this kind of like it's in the unit test

[11:33] Christopher David: But it's kind of a feature test where

[11:35] Christopher David: Running the stuff to call a host function now this one here is gonna fail because it's using some

[11:43] Christopher David: New code and chat to be to give us

[11:46] Christopher David: For sort of like our implementation says you should probably call plug-in colon and

[11:52] Christopher David: host function

[11:54] Christopher David: Why though why does it want to do this? Let's let's read what chat GPDs will actually do in here. So

[12:00] Christopher David: We're setting them up key value store. We're defining this thing if needed for host function parsing reading stuff

[12:06] Christopher David: Defining a kv read host function with these i64 string bubble blot which is from the example

[12:13] Christopher David: code defined the kv right host function sure

[12:17] Christopher David: Uh

[12:19] Christopher David: Calling with a plug-in. Yeah, I

[12:22] Christopher David: Don't know why this is needed why why why are you doing this?

[12:28] Christopher David: Let's just try um getting rid of this kind of do it fancy like and do like shift v

[12:33] Christopher David: j

[12:35] Christopher David: jcc boom

[12:38] Christopher David: someday i'll be fast at that. There's way to do that with a few or keystrokes but

[12:43] Christopher David: um

[12:45] Christopher David: assuming they get to code and they're code out of curiosity how does it fail out if it does it will probably fail what it what happens

[12:53] Christopher David: Unable to load plug-in

[12:56] Christopher David: Unable to create xism plug-in unord import xism colon host size user colon colon kv read has not been defined

[13:04] Christopher David: oh

[13:12] Christopher David: Because we need to define it else. Okay, let me let me get back to the actual like xism

[13:18] Christopher David: Demo code and not use this

[13:21] Christopher David: bastardized charity version of it

[13:24] Christopher David: host functions

[13:27] Christopher David: new plug-in

[13:35] Christopher David: So I don't know if we've exposed that part of it

[13:42] Christopher David: plug-in is new plug-in we need to pass these imports to the plug-in to create them

[13:49] Christopher David: All imports of a plug-in must be satisfied. Okay, so this just might be

[13:53] Christopher David: um we didn't implement that part of it. I don't know if this has to be assigned when you create the plug-in

[14:00] Christopher David: But let's just go take a look at where we're doing that and if i'm cool i'll do gb there and boom there we go

[14:06] Christopher David: Okay, so plug-in when i'm doing parts we are doing i think this

[14:17] Christopher David: call

[14:23] Christopher David: Okay, so i might just be able to pass in the functions

[14:27] Christopher David: come back to here. Yeah, yeah, yeah, yeah, yeah, yeah, see if we're gonna do

[14:35] Christopher David: Functions boom right there and then over here in plug-in

[14:40] Christopher David: we're gonna say you can optionally give me some

[14:45] Christopher David: functions

[14:47] Christopher David: oops

[14:49] Christopher David: So just say i don't know, optionally pass in functions to go to the plug-in

[14:57] Christopher David: and it can just call this you know what this can be mixed

[15:02] Christopher David: is it mixed i don't know anything about piece we type mixed you know functions

[15:08] Christopher David: equals

[15:10] Christopher David: nothing

[15:12] Christopher David: okay and then

[15:15] Christopher David: just like hurl it into the hurl it into there

[15:20] Christopher David: plug-in call or do you want me to find it

[15:24] Christopher David: want me to find it and then you call it

[15:32] Christopher David: Yeah, maybe and then make sure we're passing those in

[15:38] Christopher David: we are

[15:41] Christopher David: Okay, the first thing i want to do is

[15:44] Christopher David: DDL with this does

[15:49] Christopher David: just make sure we have some kind of output there

[15:53] Christopher David: we do

[15:57] Christopher David: Now we're initializing the kd store every time so if i run it again it's still gonna be three

[16:02] Christopher David: because the state is resetting between test runs but if i

[16:06] Christopher David: run it twice

[16:15] Christopher David: i would hope to see

[16:23] Christopher David: different output

[16:26] Christopher David: wow

[16:32] Christopher David: i'm able to look plug-in and i'm able to create xism plug-in i'm not in poor oh oh

[16:39] Christopher David: well what what because this what this is doing is um

[16:43] Christopher David: it's initializing it every time

[16:49] Christopher David: so what everything to do is pass that into maybe the constructor

[16:54] Christopher David: see look at me i'm like using my brain rather than

[17:02] Christopher David: sometimes i feel good to think i want to think by myself a little bit

[17:05] Christopher David: okay so when we create the function

[17:09] Christopher David: yeah the problem is that we are defining a function every time we call

[17:26] Christopher David: and we don't want that let me just try to like rethink through this myself

[17:30] Christopher David: so maybe instead of doing this every time we call let's just do this one so we construct the plug-in

[17:47] Christopher David: where i really want this to do is just be like this

[17:52] Christopher David: plug-in call

[17:53] Christopher David: and then when i put these things in the constructor

[18:10] Christopher David: make a constructor

[18:16] Christopher David: yeah

[18:23] Christopher David: when we construct it then we're going to want to pass in the wason URL

[18:30] Christopher David: the functions maybe yeah

[18:38] Christopher David: let's save even the manifest

[18:45] Christopher David: reminding what we might want that i don't know if we'll need functions saved

[18:54] Christopher David: and then we'll call it this plug-in

[19:02] Christopher David: so we don't want instead of every call and then we'll call this

[19:06] Christopher David: private wasm URL private manifest private plug-in

[19:12] Christopher David: come back down here now we got some problems

[19:17] Christopher David: wasm bytes this wasm URL

[19:23] Christopher David: was the problem see i don't have any way of error checking this because i don't

[19:28] Christopher David: forget what the command is or i don't know what the hotkeys

[19:34] Christopher David: maybe it says i don't know if that's a string

[19:37] Christopher David: how do i say that's a string we might type that

[19:45] Christopher David: come with that oh yeah it's like giving them types

[19:51] Christopher David: give me them types now it's going on here

[19:57] Christopher David: probably yeah i don't know what that is

[19:59] Christopher David: exports. Oh, we got all sorts of tight complaints now. Okay, so for call, we're not doing that. I just want the function name. Don't give me the functions. And then what we need to do is

[20:20] Christopher David: when we construct the plug-in, when we construct the plug-in, when we thought I could

[20:37] Christopher David: put with how it handles models.

[21:07] Christopher David: Well, I'm probably not going to be able to do a factory there.

[21:25] Christopher David: Hmm, this would be interesting.

[21:37] Christopher David: Okay, so new plug-in with the WASM URL.

[22:08] Christopher David: And the functions.

[22:25] Christopher David: Okay, then down here we don't grab that.

[22:37] Christopher David: Okay, so we're going to do a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit of a little bit

[23:07] Christopher David: that should be nine vowels, better be nine vowels. Oh yeah, so nice. Okay.

[23:24] Christopher David: I don't know if there's some problems with defining it like this if this bypasses like

[23:30] Christopher David: a model model handler create blah blah blocks or not creating it and defining it as new with the

[23:37] Christopher David: constructor that may not be a best practice but right now it works our test pass while our test doesn't pass

[23:41] Christopher David: I did a see. Expect the code to keep you have total expected to be greater than zero.

[23:51] Christopher David: I mean I'm expecting it to be nine.

[23:53] Christopher David: Now what is this console? I'm being pretty robust here.

[24:08] Christopher David: Oh that's defining our host function. Where's that come from? Oh yeah the host function.

[24:27] Christopher David: So you be quiet. Thank you and you be quiet. And then let's clear out of there.

[24:36] Christopher David: Okay. I'm expecting the code to total to be equal to nine.

[25:06] Christopher David: Oops oops oops oops oops oops oops.

[25:14] Christopher David: Two equal is that I forget if that's a thing.

[25:25] Christopher David: Uh yeah, not zero.

[25:28] Christopher David: Oh that's nice. That's really nice. Okay we officially have host functions working in

[25:43] Christopher David: Okay so we just got to fix this.

[25:58] Christopher David: Cassandra writes a property plug-in was we are of type strain.

[26:07] Christopher David: If then just return. Okay just don't complain if I don't pass anything.

[26:18] Christopher David: Oh the problem is it might already have a different problem. Thanks.

[26:31] Christopher David: All right let's fix this to do now.

[26:48] Christopher David: Okay.
