9333 :: Load Assets From Memory

• wwderw (orginal) [2022-07-30T22:56:57+02:00] view original

  I'm using nimassets to bundle in all my assets for the program and I was wondering if there is a way to pull it from that base64 without having to write it to client's harddrive first?

  I know using C++ I can use ld to create .o files and from there in code define DATA and SIZE and get it loaded in that way. Is there an equivalent method in Nim using nimassets (or other method)?

  Thanks!

  I don't think I understand your question. nimassets just creates a Nim module with a table that has inside the raw files contents encoded in base64, then when you compile the main module that imports the assets module, the data is "bundled" there in the compiled binary. I don't see how to load the assets from memory since they're stored at the compiled file, not loaded form anywhere.

  Nimassets also has the built into ability to load that table as a ByteSeq. I could be wrong about it, but I would view that as it would be a memory buffer at that point. I could be wrong (probably am, I tend to know just enough to cause damage).

  Unless I am wrong about this exported function with Nimassets: getAssetToByteSeq().

  You can use staticRead which will embed a file into your executable. The resulting data is loaded with your program and is not written separately to the disk.

  That may work and from there make it a stream. Just so long as the other libs have fileFromStream() (or something along those lines) to take it from there.
