playground/internal/imports: add syscall/js identifiers

dmitshur · dmitshur · commit 0aede165a0e2 · 2019-12-01T21:25:02.000-05:00
GopherJS 1.12-2 has added support for syscall/js package, so it should be available as part of imports. The syscall/js API is not included in the GOROOT/api/go1.*.txt files at this time, and so it needs to be added to mkstdlib.go explicitly. Use the mkapi.go program to determine the syscall/js API. Regenerate zstdlib.go with the updated generator, using Go 1.12.13: go1.12.13 generate github.com/gopherjs/gopherjs.github.io/playground/internal/imports Updates golang/go#27590
