Bug Report

Environment

OS

Operating System: Windows 11 24H2

MoonBit CLI Tools Version

moon version --all
moon 0.1.20241218 (5a38a2f 2024-12-18) ~\.moon\bin\moon.exe
moonc v0.1.20241218+f4a066f5f ~\.moon\bin\moonc.exe
moonrun 0.1.20241218 (5a38a2f 2024-12-18) ~\.moon\bin\moonrun.exe

And I'm using dev version of core 1fae2a3

Steps to Reproduce

Using Pwsh, clone moonbitlang/core

PS T:\> # Checkout with LF
PS T:\> git config --global core.autocrlf false
PS T:\> git config --global core.autocrlf
false
PS T:\> git config --global core.eol
PS T:\> git clone https://github.com/moonbitlang/core.git

Run moon fmt

PS T:\> cd .\core\
PS T:\core> git status
On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean
PS T:\core> git diff
PS T:\core> moon fmt
PS T:\core> git diff
PS T:\core> git status
On branch main
Your branch is up to date with 'origin/main'.

Run moon info

PS T:\core> moon info
Finished. moon: ran 90 tasks, now up to date
PS T:\core> git diff
diff --git a/array/array.mbti b/array/array.mbti

Another way of reproducing:

PS T:\> # Checkout with CRLF
PS T:\> git config --global core.autocrlf true
PS T:\> git clone https://github.com/moonbitlang/core.git core-crlf

Expected Behavior

• moon fmt and moon info have the same behaviour.
  Both use LF, or CRLF, or are configurable, or keep EOL unchanged.
  like https://github.com/rust-lang/rustfmt/blob/8a2c07398845420d7951d2f4e83d5f97c4df0875/src/config/options.rs#L20

I would recommend keeping the EOL unchanged, as users may be using platform-specific EOLs, or automatically switching EOLs at check-in, commit, etc. with tools like git.

Actual Behavior

• moon fmt always generates LF as EOL on Windows.
• moon info always generate CRLF as EOL on Windows.

Checklist

• (Optional) My case is minimal enough to be reproducible.
