Expose original non-replaced single artifact fields

[Elara6331]

Is your feature request related to a problem? Please describe.

GoReleaser exposes various information for single artifacts via templates, as mentioned in https://goreleaser.com/customization/templates/#single-artifact-extra-fields. I have binaries generated by xgo that need to be placed inside an archive. Binaries compiled by xgo use the Go naming convention for architectures, so amd64, arm64, etc.

I also instruct users to choose the correct file to download by using uname -m. This means I have to use replacements to make it match that convention (x86_64, aarch64, etc.).

This makes it impossible to use {{.Arch}} to select the correct binary.

Describe the solution you'd like

I'd like there to be new template fields for non-replaced values, maybe something like {{.OriginalArch}}

Describe alternatives you've considered

I could remove the replacements, but this would make it a lot harder for users to download the correct file for their machine. I could also use a template string with a bunch of if statements to convert it back, but that isn't a very good solution.

I've been thinking more and more about actually dropping the replacements in favor of something else, because it is, well, a bit weird.

Anyway, in your case, you can drop the replacements thing, and set your archive.name_template like this:

archives:
  - name_template: >-
        {{- .ProjectName }}_{{ .Version }}
        {{- if eq .Os "darwin" }}Darwin{{ end }}
        // etc..
        {{- printf "_" }}
        {{- if eq .Arch "amd64" }}x86_64{{- end }}
        // etc
