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.
Also introduces testing of our CLI's output via `assert_cmd`. Expect some follow
ups to get more of our testing infrastructure using this incredible crate!
Fixes#511
This commit replaces the `slog` family of crates used by `wasm-pack`
with the `log` crate plus `env_logger`. This also means that by default
`wasm-pack` also won't create a `wasm-pack.log` file in the current
directory. Enabling logging will now be done through
`RUST_LOG=wasm_pack` instead of `-v` flags.
Closes#425
This commit switches wasm-pack to using a global cache for all download
binaries, living typically in a user's home directory. The intention
here is to aovid creating a `bin` folder in all wasm-pack projects and
additionally share downloads between projects to ensure that you're
downloading a minimal number of binaries from the network.
Along the way the downloading code was restructured to support a global
cache, but everything should largely be as it was before!
Closes#292
