//! Self-installation of `wasm-pack`
|
||||||
|
//!
|
||||||
|
//! This module contains one public function which will self-install the
|
||||||
|
//! currently running executable as `wasm-pack`. Our goal is to install this in
|
||||||
|
//! a place that's already in `PATH`, ideally in an idiomatic location. To that
|
||||||
|
//! end we place `wasm-pack` 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.
