Back in February there was a discussion about how hard it is to modify
vendored Rust crates for Stylo. I can't actually find any solution to
that problem - the general idea appears to be "add a [replace] section
to a Cargo.toml and run cargo update", but I have not been able to make
that work yet. Given that the version of mozilla-central that I'm using
contains a vendored copy of rust-cssparser 0.12.2, here's what I have tried:
* added the following to servo/Cargo.toml and toolkit/library/rust:
[replace]
"rust-cssparser:0.12.2" = { path = "/Users/jdm/src/rust-cssparser" }
* run `cd servo/Cargo.toml && cargo update -p cssparser`
* run `cd toolkit/library/rust && cargo update -p cssparser`
This ends up modifying the Cargo.lock files to use the most recent
version from crates.io (0.12.4) instead of my local copy. Has anybody
been able to make this work? Can we please document the exact steps to
follow? There have been multiple people asking in #servo how to do this
recently and nobody seems to have done it successfully.
Cheers,
Josh
