In the added test, the unexported field used to be garbled.
Reflection can only reach exported methods, exported fields, and
unexported fields. Exported methods and fields are currently never
garbled, so unexported fields was the only missing piece.
Carefully select a default that will do the right thing when inside a
module, as well as when building ad-hoc packages.
This means we no longer need to look at the compiler's -std flag, which
is nice.
Also replace foo.com/ with test/, as per golang/go#37641.
Fixes#7.
We use 'go list -json -export' to locate required modules. This works
fine to locate direct module dependencies; since we're building in the
current module, we run 'go list' in the correct directory.
However, if we're building one of those module dependencies, and it has
other module dependencies of its own, we would fail with cryptic errors
like:
typecheck error: [...] go list error: updates to go.sum needed, disabled by -mod=readonly
This is because we would try to run 'go list' outside of the main
module, probably inside the module cache. Instead, use a $GARBLE_DIR env
var from the top-level 'garble build' call to always run 'go list' in
the original directory.
We add a few small modules to properly test this.
Updates #9.
The problem with the "grep" built-in command is that it prints the
entire data if there is an error. We don't want megabytes of binary
output for a test.
