hanxue-mac: idea hanxue $ ls doc / scala -devel-docs / api index index.js package.html index.html lib scala hanxue-mac: idea hanxue $ ls / usr / local / opt / scala / idea doc lib src hanxue-mac: hanxue idea $ ls / usr / local / opt / scala / idea / doc / scala -devel-docs / api index index.js package.html index.html lib scala
