Mommy can't check rust-analyzer if I ask her for debuginfo

[saethlin]

With this config:

[rust]
debuginfo-level = 1

Try to use mommy via x by doing this hack I copied from @Nilstrieb:

alias x="CARGO=x cargo-mommy"
x check src/tools/rust-analyzer

But I get this:

error: failed to run custom build command for `proc-macro-test v0.0.0 (/home/ben/rust-master/src/tools/rust-analyzer/crates/proc-macro-test)`

At a glance,

"/home/ben/rust-master/x" "build" "-p" "proc-macro-test-impl"

Seems like the problem, because you can't just replace cargo with x. But why does this work for everything else? And why does it work with debuginfo-level = 0?

[Noratrieb]

Gankra/cargo-mommy#62 will probably fix this

[saethlin]

Yup, this works:

alias x="CARGO_MOMMYS_ACTUAL=x cargo-mommy"

the proc-macro-test build script is using CARGO somewhere
