When importing txt files, "\n"s in the txt file are converted to newline

[lirc571]

What version of Bun is running?

1.0.33+9e91e137f

What platform is your computer?

Linux 5.15.133.1-microsoft-standard-WSL2 x86_64 x86_64

What steps can reproduce the bug?

text.txt:

printf("Hello, world\n");

index.ts:

import text from "./text.txt";

console.log(text);

bun run index.ts

What is the expected behavior?

The following should be printed to the console:

printf("Hello, world\n");

What do you see instead?

printf("Hello, world
");

Additional information

txt files should be loaded as is.

Hi @lirc571. Thanks for raising this.

I don't believe this is a bug. If imported text is a string with the content as is. When you pass the text as is to console.log it will interpret the \n as such. What you may be wanting is to escape newlines before passing it to console.log. Something like console.log(text.replaceAll("\n", "\\n")).

Hi @jdalton , the problem is not with console.log. The text file should be read as "printf(\"Hello, world\\n\");", but Bun instead changed the \n to a newline character.

I believe a file reading operation should treat the file's content as is. The 2 snippets below should produce the same result:

import textFromImport from "./text.txt";

vs

const file = Bun.file("./text.txt");
const textFromFile = await file.text();

But they are different.

Thank you @lirc571!

I also verified the difference in Node:

import fs from "fs";
const file = fs.readFileSync("./text.txt", "utf-8");
console.log(file); // logs printf("Hello, world\n");
