* All messages are now printed onto stderr instead of some on stdout and
some on stderr
* All messages uniformly are prefixed with an emoji with consistent
spacing.
This commit moves wasm-pack further along the spectrum towards the 1.0
output previously discussed at the last work week. The changes here are:
* Steps which execute near instantaneously no longer print informational
messages by default.
* Long-running steps like downloading chromedriver/geckodriver now only
print if they actually perform a download.
* The "add wasm target" step now prints nothing if the wasm target is
already installed.
* Child process output is no longer captured and is redirected natively
to the terminal, granting colors from rustc/Cargo as well as Cargo's
progress bar during a build.
This commit is the first in what is hopefully a series to help move
`wasm-pack`'s CLI output and interactions to a "1.0 status". This was
[discussed at the recent Rust All Hands][discussion] where the salient
points we ended up extracting were:
* At all times if a user is waiting for `wasm-pack` to finish it should
be clear what's being waited on.
* As an example, Cargo's own output shows what crate is being built.
* As another example, something that always takes only a handful of
milliseconds to complete doesn't need an informational message.
* The final output products of a command should always be clear and
printed. For example the output location of artifacts should always be
printed.
* The `wasm-pack` CLI tool should use "progressive enhancement" to
incrementally detect features of the output it can use (like colors,
emoji, etc) but always work in the absence of these features. This'll
help us support a wide range of use cases and terminals.
The goal of this commit is to not get us all the way there but start us
down the path to satisfying these goals. To that end the major change
here is to remove the dependency on `indicatif`. Using `indicatif`
requires that all output is piped through the `indicatif` crate itself,
which causes the third item here to not work for one of the main parts
of `wasm-pack build`, the `cargo` pieces. Cargo (and the Rust compiler)
are unable to use thir own tools for progressive enhancement when the
output is captured and sent through `indicatif`.
Lots more refactoring will be needed internally to fully polish off the
input/output to a "1.0 status", but this is hopefully a good start!

A few assorted improvements to the prerequisites documentation:
* Rust nightly/beta requirements are removed
* Wording indicating that `wasm-pack` requires `npm` has been clarified
* The dedicated Rust page was removed as it's largely just "install
Rust" nowadays
* The heading of the NPM page in the sidebar now includes `(optional)`
to clarify that it's not required.
First check if wasm32-unknown-unknown is present in rustc's
sysroot and if it is, then we're fine. Otherwise check if we're using
rustup and add the wasm32 target and if we're not using rustup, then
bail with an error stating that the wasm32 target couldn't be found.
This commit adds support for the new `--web` flag in `wasm-bindgen`
under the flag name `--target web`. To ensure that it was plubmed around
the stringly-typed `target` type was switched to an `enum Target` to
ensure that all cases it's looked at are handled appropriately for the
new `web` target.
This commit adds a header dialog to the gh-pages mdbook documentation of
this repository to indicate that it represents unpublished documentation
that may not reflect the currently published version of `wasm-pack`. The
header redirects users to https://rustwasm.github.io/docs/wasm-pack/
which has the documentation for the latest published version of
`wasm-pack`.
