Fixes #2189.

Does this PR introduce a breaking change?

• [x] Yes
• [ ] No

If indicated yes above, please describe the breaking change(s).

Release binaries for Linux, macOS, and Alpine now have their arch suffixed to their names. Prior to the change, release binaries were named:

• spectral-linux
• spectral-macos
• spectral-alpine

They are now:

• spectral-linux-x64
• spectral-linux-arm64
• spectral-macos-x64
• spectral-macos-arm64
• spectral-alpine-x64
• spectral-alpine-arm64

The installation script has been updated to work with this change, but it breaks workflows for users or systems who depend on the original naming pattern.

I can copy the x64 binaries to files with their original name to prevent the BC break, but that could make the file list in the release look a little confusing.

Additional context

Unrelated to binary builds is a fix to the installation script that will prevent bugs when executing the script from a directory with a space in its name.

Thanks for checking this out! I'm open to commentary and suggestions.

I fixed the PR's subject to conform to Conventional Changelog's formatting, but can't re-run the lint job to verify. I'm afraid one of y'all may need to re-run it to verify it passes now.

Hi. I face an issue in downloading the image in install.sh. I get the below error: Error requesting. Download binary from https://github.com/stoplightio/spectral/releases/latest/download/spectral-linux-x64 while https://github.com/stoplightio/spectral/releases/latest/download/spectral-linux is working fine.

This is the link to the doc: https://meta.stoplight.io/docs/spectral/b8391e051b7d8-installation#executable-binaries

Is there a plan to fix this issue? Is it possible to upload the binaries with arch-suffix?

Thanks!
