This is a less extreme version of #1208, which only marks snippets and the main file on the bundler target as having side effects instead of all files.
This means that the shim file which contains the vast majority of the JS code is still properly marked as having no side effects, allowing bundlers to get rid of things like unused `new TextEncoder` calls which could theoretically have side effects but don't.
Fixes#972.
* 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.
* 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 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 fixes an issue where if a library is renamed via the `name`
key in the `[lib]` section of the manifest then `wasm-pack` would try to
generate bindings for an noexistent wasm-file, generating an error.
The fix was to internally use `cargo_metadata` more aggressively and
move around where this data is generated. This ended up refactoring a
few locations, but this should also bring improved error messages for
`cargo metadata` as well as caching the resulting data more aggressively
to avoid recalculating it too much.
Closes#339
This lets us leverage `cargo` for semver finding and then ensure that we get the
exact same version of the CLI that cargo selected. It also lets us support fuzzy
dependencies like "0.2" instead of exact dependencies like "0.2.21" again.
