mise fetches incorrect installer / binary resource (MSI sometimes, macOS app sometimes)

[freak4pc]

In the latest versions of mise, running mise install for swiftformat downloads the MSI binary from the release (which is Windows-specific) even though I'm on a Mac.

This causes this kind of failure:

The mise.toml is here: https://github.com/ReactiveX/RxSwift/blob/main/mise.toml

When looking in ~/.local/share/mise/installs/swiftformat/0.58.7

In v2026.1.7 - it downloads an MSI file
In v2025.12.13 - it downloads a macOS executable instead of the CLI
In v2025.12.2 - it works correctly, downloading the CLI

(I didn't check builds in between, just kinda tried jumping between releases).
If I can provide any extra info, happy to.

Thanks for reporting this! I found the root cause.

The problem: The asset matcher wasn't recognizing .msi as a Windows-specific format. It only looked for text patterns like "win", "windows" in filenames.

For SwiftFormat's releases:

• SwiftFormat.arm64.msi scored +50 (arm64 match, no OS penalty)
• swiftformat.zip (correct macOS CLI) scored only +5

The .msi file won because of the architecture match bonus, even though it's a Windows installer.

The fix: PR #7838 adds .msi and .exe as Windows-specific indicators. These now get:

• +100 on Windows
• -100 on non-Windows platforms
