Module wrangler::installer

Self-installation of wrangler

This module contains one public function which will self-install the currently running executable as wrangler. Our goal is to install this in a place that’s already in PATH, ideally in an idiomatic location. To that end we place wrangler next to the rustup executable in PATH.

This installer is run directly (probably by clicking on it) on Windows, meaning it will pop up a console (as we’re a console app). Output goes to the console and users interact with it through the console. On Unix this is intended to be run from a shell script (docs/installer/init.sh) which is downloaded via curl/sh, and then the shell script downloads this executable and runs it.

This may get more complicated over time (self upates anyone?) but for now it’s pretty simple! We’re largely just moving over our currently running executable to a different path.
