A recent commit ensured that the pkg directory was removed as the first step of creating it. Unfortunately, this causes a problem for tools such as webpack when watching the pkg directory. In the case of webpack, it is unable to recover its watching and so any watch server must be restarted, consuming the developer's time.
* Renamed set_crate_path to get_crate_path
* If the path isn't specified in the call then use the current_dir and walk up the path try to find the manifest file.
* Specify the cwd for the build test so it doesn't walk up the path. The test needs to specify the path to build, otherwise because fixtures are run in a subdirectory of the source tree it will find the Cargo.toml from the wasm-pack source repository.
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!
