[feat] beforeBuildCommand/beforeDevCommand needs a target triple environment variable

[WilliamVenner]

Describe the problem

beforeBuildCommand and beforeDevCommand claim to be for conditional compilation, yet offer no way of getting the target triple for building

Describe the solution you'd like

Expose the target triple as an environment variable

did you check https://tauri.app/v1/api/config#buildconfig.beforedevcommand there is env vars for arch, platform, ..etc

[WilliamVenner]

Yes, they can't be used to build a target triple

[FabianLars]

Why not? you only need arch and os to figure out your target triple. That's of course not nearly as comfortable to use, but still not impossible.

[WilliamVenner]

x86_64-windows-pc-msvc

[arch] [os] [???] [toolchain]

the last two are missing

[FabianLars]

Yes they are missing, but in the context of tauri apps, predictable.

• windows? arch + pc-windows-msvc
• linux? arch + unknown-linux-gnu
• macos? arch + apple-darwin

[WilliamVenner]

But then there's the issue of concatenating these strings in a cross-platform way. Now I have to resort to a scripting language or something just to concatenate these parts into a target triple.

[FabianLars]

Yep, that's why i said it's "not nearly as comfortable to use". it's a workaround not a solution, which is why this issue is still open. In other words, we/i agree that this would be a nice addition 👍
