Just wanted to let you know that, as of da29859, blindly following https://github.com/google/mangle#building--testing fails:

@burakemir & @mihaimaruseac FYI

@teivah just in case you are bored and looking for 😸 something to contribute to...

FYI I've still managed to run it, these appear to be "just" test failures, not preventing building the binary:

$ go install ./...

$ ~/go/bin/mg

<decl>.            adds declaration to interactive buffer
<clause>.          adds clause to interactive buffer, evaluates.
?<predicate>       looks up predicate name and queries all facts
?<goal>            queries all facts that match goal
::load <path>      pops interactive buffer and loads source file at <path>
::help             display this help text
::pop              reset state to before interactive defs. or last load command
::show <predicate> shows information about predicate
::show all         shows information about all available predicates
<Ctrl-D>           quit

One needs to run go get -t ./... to get all the dependencies used for testing. I will update the README.md
