@LyricLy Done.

10 hours later…

@AndrewSavinykh Hm, I can't seem to repro that. Can you give me a link?

1 hour later…

Erik the Outgolfer

12:33

@Dennis can you pull 05ab1e please?

3 hours later…

fergusq

15:30

@Dennis can you pull Tampio, please?

Dennis

15:46

@EriktheOutgolfer @fergusq Syncing.

Okx

15:58

@Dennis could you guide me on how use tio to evaluate some code in some language? I've asked about this before but the links provided by Andrew no longer lead me anywhere

Dennis

@Okx Unless fill out the fields and click run answers it, I'm afraid I don't understand the question.

Okx

well, basically how to use the api

i didn't word that very well

Erik the Outgolfer

@Dennis thanks now I can use ÅP :)

Dennis

16:23

@Okx Requests consist of 6 different commands. You need three of them (create File, declare Variable, and Run) for a simple request. V must be followed by a NUL-terminated variable name, an array length n (decimal, then NUL), then n NUL-terminated strings. F must be followed by a NUL-terminated file name, a file size (decimal, then NUL), then the contents of the file. You need at least Vlang to pick a language and F.code.tio for the code. R runs the state.

Okx

i see and where do i make the request

Dennis

tio.run/cgi-bin/run/api

Okx

and POST?

and an example request would be extremely helpful

Dennis

Yes, POST.

@Okx You can run stateToByteString() in your browser's console to see what would get sent to the browser.

Ah, I forgot, you have to DEFLATE the command string after building it.

deflate(stateToByteString()) shows the result of that.

Okx

what do you mean see what would get sent to the browser? i don't believe browsers can trivially make post requests

Dennis

16:37

Of course they can. TIO does.

muddyfish

They can, jquery and such with ajax

Dennis

Or simply XMLHttpRequest.

Okx

oh i get what you mean now nvm

but you saying 'browser's console' meant that i could do it in the browser without code

Okx

17:03

So, I think I have a good request, but I get
Date: Sun, 03 Sep 2017 17:03:01 GMT
Server: Apache/2.4.27 (Fedora) OpenSSL/1.1.0f-fips
Access-Control-Allow-Origin: *
Content-Length: 0
Connection: close
Content-Type: application/octet-stream
This is not in a browser so there is no stateToByteString()

Dennis

That's not the complete response. I see no status code.

Okx

it's all the headers i get

ah status code

400

that means bad request so i'll give you my post Vlang\0001\000Neim\000F.code.tio\0001\0002\000R

\000 is Java's null byte

Dennis

17:19

Neim should be neim. Lengths and sizes are in decimal, so 1 instead of \0001. I see no code. What are you trying to execute?

@Okx Oh, and it has to be tio.run/cgi-bin/run/api. Sorry about that.

Frickin' chat. https://tio.run/cgi-bin/run/api/ (note the trailing slash)

Okx

ahah i get ETFbD7zMIykv0hvT i assume that is deflate?

Dennis

No, DEFLATE would look like gibberish, not alphanumeric. That's the internal separator.

Is that the entire response? What are you sending now?

Okx

just lowercased the neim

\0001 is NULL + 1

Dennis

Right, octals.

Okx

new headers are Date: Sun, 03 Sep 2017 17:27:40 GMT
Server: Apache/2.4.27 (Fedora) OpenSSL/1.1.0f-fips
Access-Control-Allow-Origin: *
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/octet-stream not sure how to decode the response

Dennis

17:29

Well, what response did you get? If it's just ETFbD7zMIykv0hvT, the response is empty.

Okx

mL68/Icxw78FuqVk now

Dennis

Yes, it's pseudo-random.

The content of files isn't NUL-terminated. F.code.tio\0001\0002\000R should be F.code.tio\0001\0002R.

Okx

Dennis

Because there is none. 16 bytes means there is no response.

Okx

i get Esj4adaiwafFKY6q then

hmm

My parameter is now "Vlang\0001\000neim\000F.code.tio\0001\0002R" and the response is 9aFCLD55HzmteORB which is 16 bytes

Dennis

17:36

No repro.

Okx

what's this zopfli/zopfli --deflate req doing?

Dennis

DEFLATE the request.

Okx

should i add any headers to my request?

Dennis

Any moderately high-level API should add all the required headers by itself.

What exactly are you executing when you get the 16-byte response?

Okx

what i said "Vlang\0001\000neim\000F.code.tio\0001\0002R" my library doesn't seem to add any headers by itself

Dennis

17:42

Not the string, the actual code.

Okx

HttpClient httpClient = HttpClientBuilder.create().build();

HttpPost request = new HttpPost("https://tio.run/cgi-bin/run/api/");
StringEntity params = new StringEntity("Vlang\0001\000neim\000F.code.tio\0001\0002R");
request.setEntity(params);

for(Header header : request.getAllHeaders()) {
System.out.println(header.getName() + ": " + header.getValue());
}

System.out.println("Executing...");

HttpResponse response = httpClient.execute(request);

for(Header header : response.getAllHeaders()) {

Dennis

You're not deflating the request.

Okx

i didn't realise i had to deflate the request :P

Dennis

1 hour ago, by Dennis

Ah, I forgot, you have to DEFLATE the command string after building it.

Okx

hey i got it to work

now what do i do with that garbage? :P

ah it must be deflate encoded
