03:17 <samth> willghatch: my initial feeling about extenor is that it addresses all my concerns with structs currently, but is a bigger step from structs than what I think I'm looking for, although I of course haven't tried working with it. Things I want from structs: functional update, including nested, short syntax for field access, runtime reflection on field names, nice ways of doing multiple functional updates at once. both otherwise mostly keeping structs the

03:17 <samth> way they are.

11:29 <srandon111> hello all, is there a way to create a standalone statically-linked executable from a racket program?

11:32 <nperez_> Yes: https://docs.racket-lang.org/guide/exe.html

11:33 <nperez_> but I'm just starting to learn, so other people might have better resources. I had your question recently and found it there in the racket guide

11:47 <dzoe> srandon111: as nperez_ says - generally speaking, `raco exe' is your friend (but definitely read the docs - some of the platform-dependent options can make your life easier, if you know about them).

11:48 <nperez_> dzoe, and there is the matter of how the platform racket bin is compiled (statically/dynamically), correct?

11:57 <srandon111> nperez_, i read the doc and i tried raco exe --embed-dlls --orig-exe cat_animation.rkt

11:57 <srandon111> but the thing is that when i try to execute on another machine, it complains about not finding the image of the cat

11:58 <srandon111> how can i embed the image wihtin the executable ???

11:58 <nperez_> Oh wow, no clue. My understanding of the process is very rudimentary: basically it glues your source file together with the platform bin

11:59 <nperez_> I don't know how much influence you have over that process

11:59 <srandon111> nperez_, okok

11:59 <nperez_> But for a dumb idea: you could base64 encode the image directly into a source file

12:23 <srandon111> nperez_, yes this is a workaround i know, but still i would like more to understand how to embed these files into the exe

13:47 <dzoe> srandon111: This is how I do it: https://gitlab.com/racketeer/rcge-tut25/-/blob/master/rcge/embedding.rkt

13:57 <dzoe> nperez_: --orig-exe should do the trick, also --gui if you plan on using the gui and if you use gui dynamically than ++lib racket/gui might be needed.

14:24 <srandon111> dzoe, i don't understand how to use embedding.rkt

14:24 <srandon111> dzoe, what should i do ?

14:36 <srandon111> make-immutable-hash: this function is not defined

14:39 <srandon111> dzoe, are you there?

14:52 <srandon111> dzoe, nperez_ basically my problem is tht the function i am using place-image from the standard library, requires a path... how can i solve this?

14:58 <bremner> srandon111: it sounds like you are looking for some kind of "installer". The closest is probably a package, installed with raco pkg install, but that won't be a standalone exe

14:59 <bremner> I don't know of a racket tool to bundle files into a standalone installer.

15:00 <srandon111> bremner, no no i want a standalone executable

15:00 <srandon111> not installer

15:00 <srandon111> a single exe file

15:06 <bremner> that sounds difficult to achieve, at least for code that loads "resources" from the file system. You could make a "prelude" that writes files into the right place, or not read files.

15:21 <dzoe> srandon111: it is not intended for direct usage if you do not know how it works - it is an example of how to do embedding.

15:21 <dzoe> srandon111: roughly speaking, it reads certain files during syntax stage and provides them as byte strings for runtime

15:22 <dzoe> I have to look how place-image works - never seen this one.

15:23 <dzoe> srandon111: are you using htdp language?

15:24 <dzoe> I am using racket/draw to load bitmaps (which is easy from byte strings)

15:44 <srandon111> dzoe, yes

15:44 <srandon111> dzoe, i am using place-image

15:45 <srandon111> and would like to understand if there is a workaround so that i can pass those bytes to place-image

16:31 <samth> srandon111: you probably want `raco distribute`

16:31 <samth> but that does not create a single file where files that you depend on at runtime are included in the executable (I don't know of any language that has a tool like that)

16:33 <samth> srandon111: if you want to include the contents of an image in your file, you can use `color-list->image`

16:34 <samth> srandon111: you might also be interested in https://docs.racket-lang.org/images/Embedding_Bitmaps_in_Compiled_Files.html?q=static-bit#%28form._%28%28lib._images%2Fcompile-time..rkt%29._compiled-bitmap%29%29

23:57 <nperez_> samth, "(I don't know of any language that has a tool like that)" .NET stuff does. Super easy to embed/access a resource inside the executable
