Awesome video. Helped me a lot. ⚠️You cannot "go:embed" inside functions anymore. This was removed. You need to do it at the package scope now. Hopefully this helps someone!

//go:embed goes outside the function, but this is good stuff

Pretty cool stuff. How does embedded binary files work? Also the mic audio is warmer not so hollow. Sounds good

@Tutorialedge 3 жыл бұрын

So from what I understand, the contents of the file are wrapped up in the compiled binary that is generated when you run your go build ./... command. This means that everything your application needs to effectively work with that file is encapsulated in the binary itself. Also, thanks for the feedback on the audio! I'm delighted with how it sounds with minimal to now post-processing!

It's the same as simply creating a string variable storing the content of the file. That's all. So the content of the file is stored within the program itself, which is compiled into a single binary. This is opposed to writing a program which reads from a file at runtime, meaning when you relocate the binary (uploading it to a server for example), you must move those files being read as well. Embedding the files into the binary means all you need to move is the binary itself. Something to bear in mind is that the state of the files being embedded will be as they were when the program was compiled. And also, embedding lots of files will result in a large binary size.

You prolly dont care but if you guys are bored like me atm then you can watch pretty much all the latest movies and series on Instaflixxer. Have been streaming with my girlfriend during the lockdown :)

1:30 print(s) without reading it from file is confusing, I thought you would read it as any external file, how to distinguish between multiple files?

Hi, nice video, thanks for that. I have a question, how do you manage several versions of go in windows? I have tried but I cannot execute the other version :(

@Tutorialedge 3 жыл бұрын

I don't use Go, but one approach you could use is to wrap your application in a docker container and pin the Go version you want to use within that. It keeps your machine nice and tidy without a million Go binaries on your path and allows you to develop apps that may be reliant on different versions at the same time without wasting time constantly updating your environment variables!

Wow, thanks for that, is a great idea.

Is there a way to read the content of the embed Fs folder without serving it with http server.

I'm not sure I'm a fan of certain directions the language is going in, but I can certainly see why they've incorporated these functions into the language. They are adding very opinionated ways of solving problems into the language which should hopefully ensure that the code for these systems remains as readable as possible.
