Enabling compression on socket send/receive.

Thank you Clonk, but like I said, I wanted to avoid the "ifs", and case is just an alternative if. Already know to implement it like this. My question was how I can implement it with storing the procs instead, like I said 3 times already :)

Enabling compression on socket send/receive.

not sure what you mean there Araq. That is what I want to accomplish here, write 3 procs, sendUncompressed, sendGzip, sendDeflate, and when compression is enabled, just do client.sendProc = sendGzip or whatever. And all socket sends are handled by client.sendProc(data: string). I am stuck at thi

Enabling compression on socket send/receive.

I am trying to write a NNTP client for nim, for some reason this basic ancient protocol is not implemented in any lib I could find. NNTP protocol allows for gzip or deflate compression. I know an if boolean for every send is not a big deal, but if it can be done better, by swapping assigned proc

Enabling compression on socket send/receive.

Thank you, I guess that is an acceptable workaround while keeping the same syntax of nntp.sendProc(), but the reason I wanted to store the procedure as a field in the object, is to avoid the if compress: sendCompressed else: sendUncompressed. Would avoid extra code and runtime overhead for all t

Enabling compression on socket send/receive.

bump. still no solution found yet

Enabling compression on socket send/receive.

I tried to get a proc as field in my client object, so i can swap it at runtime without having if else everywhere. I have these definitions: proc sendProcU(nntp: NNTP | AsyncNNTP, data: string) {.multisync.} = await nntp.sock.send(data) NNTPClientBase*[SocketType]

Enabling compression on socket send/receive.

already saw that example that is not relevant to the topic. if compression then send compress(string) else send string. I was looking for a more generic socket-centric solution.

Enabling compression on socket send/receive.

What would be the most simple/elegant way to have (de)compression enabled on all data sent/received over a socket ? In go it appears that it's as simple as: .. code-block:: go > conn, err := net.Dial("tcp", "localhost:8080") > > `if err != nil ...` > > gzipWriter := gzip.NewWriter(conn) messag

Newbie Here! Can I have some feedback on my code?

Since the strings use are constant, better to define them before the code, it's cleaner imho. You can use the contains proc with sets of letters, like this, instead of your loops: let shouting = phrase.contains({'A'..'Z'}) and not phrase.contains({'a'..'z'} This part is redundant " elif co

High level TUI framework (or wrapper of)

Well, I decided I will learn rust and attempt my project there. Nim ecosystem (libs and potential manpower, as well as velocity of growth) too sparse for the job unfortunately. And also because my poor coding speed and knowledge can't make up for the lacking ecosystem. Will still use Nim for sim

@oakes It would be great if you could provide a one widget example/template. Not sure how it would differ from illwillwidgets mentioned above.

High level TUI framework (or wrapper of)

Thank you enthus1ast, somehow I missed that project. I believe it is enough to get me started on it in nim. Although everything is rather primitive, no auto sizing based on terminal resize, no scrollable list for table. Do you think you have time in the near future to make the table scrollable,

High level TUI framework (or wrapper of)

I was under the impression that termbox/2 has some simple widgets, like a scrollable table, seeing made with it. But it seems it draws everything manually, and for that I could use the already existing nim lib illwill. So I can scratch the temrboxes from the l

nim merch

I agree that we should have more or less nerdy nim t-shirts, caps etc. officially. So people of the nim almost secret by obscurity society can recognize each other. Would certainly be more useful stuff to buy than Araq's book.

Need suggestions for time scheduling async tasks

Thank you for the suggestion, unfortunately the way it works is not clear to me, and how I should implement it for my use case. I realized the actual requests are done by a single procedure in my code, and I can calculate a sleep delay at the start of it, given the times previous requests were m

Need suggestions for time scheduling async tasks

I am writing a client/crawler/scraper library for a certain website, hopefully my first nimble package. The site has some rate limiting which I haven't figure out exactly yet, but will try to do. Once I do, I want to have a request scheduler so that all requests (async) done to the website are a

Help with generics and typeclass problem

You are right mratsim, it's the nim compiler that sigsegv.. which is obviously a bug, no doubt about it :) I will report it. Speaking of bugs and types, I almost forgot this little code snippet when I was trying to figure out concepts: Code behaves correctly

So I don't open another topic, I'd like to know if it's possible to use std/math ceilDiv inside a (generic) type definition, like here: this does not compile, even though const a = ceildiv(..) works, so ceildiv is good for compile time. If I write my own cei

Help with generics and typeclass problem

mratsim that might be true in general, but I want to have user-pickable uint base type for the array/seq, so openArray[byte] won't do. Also I want to have max performance, and one extra proc call is not ideal.

Optimise async request / code [For Beginners]

As far as number of lines go, you can combine the creation of http client, request, and checking for content in one line. Also, although you made an async proc, you use waitFor in a for loop, for each future, which will make the program behave just like doing non async http requests, it will mak

What would be the bast way to get parsing and validation of parameters (option:value)

Hm no, in this case I want to simply ensure the parameters that I get, from any external source, are valid in their context. They won't be used as parameters in a nim program, but to eventually execute an external binary. So cligen is not of any help. Araq's way, "default design procedural prog

What would be the bast way to get parsing and validation of parameters (option:value)

Need to parse and validate user supplied parameters for video encoders, in the form of "\--option1:value --option2 --option3:value", which are unique for each encoder we have defined. option fields must be in a set of predefined such fields, while values have to be in a certain range for integer

Any libraries for dictionary coding (compression) of array structures ?

No, it's not at all the easiest way to go at it. I don't see what I can use from there, even conceptually. This is the barebones code I wrote for this - It has some shortcomings: The algorithm to generate it is probably not optimal, checking if each new entry

Custom header values inside multi-part form ?
