error C2026: string too big, trailing characters truncated

[jonatino]

My project fails to compile when trying to embed an angular web application. Compiling VS 2019 msvc.

Here is my binfs.hpp

The longest string literal for my background.png image is 1,585,218 characters.

Hi. After googling this I found out library shoud generate strings as

char *s = "very long"
          "string";

instead of

char *s = "very long string";

to make this work in VS on Windows.

@jonatino feel free to open a pull request, otherwise I can take a look next week.

@jkuri I think we'd need to take a step farther and chunk them into separate strings entirely; it seems msvc still enforces a 65535 byte length for even contacted strings.

See https://docs.microsoft.com/en-us/cpp/c-language/maximum-string-length?view=msvc-160#:~:text=ANSI%20compatibility%20requires%20a%20compiler,C%20is%20approximately%202%2C048%20bytes.

While an individual quoted string cannot be longer than 2048 bytes, a string literal of roughly 65535 bytes can be constructed by concatenating strings.

And I've just started C++ a few days ago. I can try to get this working if not your help would be appreciated :)

sure, you are welcome to open a PR then we can check together.

btw, manually converting strings to format I mentioned above make this compile on Windows if I recall correctly, maybe this lib https://github.com/ekg/split can come handy.
