This change implements a workaround to better support composed interfaces in yaegi and let the interpreter define objects which implement multiple interfaces at once. We use the existing MapTypes to store what possible composed interface wrapper could be used for some interfaces. When generating an interface wrapper, the wrapper with the highest number of implemented methods is chosen. This is still an imperfect solution but it improves the accuracy of interpreter in some critical cases. This workaround could be removed in future if/when golang/go#15924 is resolved. Fixes #1425.

# Importing packages
|
|
|
|
Packages can be imported in source or binary form, using the standard
|
|
Go import statement. In source form, packages are searched first in the
|
|
vendor directory, the preferred way to store source dependencies. If not
|
|
found in vendor, sources modules will be searched in GOPATH. Go modules
|
|
are not supported yet by yaegi.
|
|
|
|
Binary form packages are compiled and linked with the interpreter
|
|
executable, and exposed to scripts with the Use method. The extract
|
|
subcommand of yaegi can be used to generate package wrappers.

# Custom build tags
|
|
|
|
Custom build tags allow to control which files in imported source
|
|
packages are interpreted, in the same way as the "-tags" option of the
|
|
"go build" command. Setting a custom build tag spans globally for all
|
|
future imports of the session.
|
|
|
|
A build tag is a line comment that begins
|
|
|
|
// yaegi:tags
|
|
|
|
that lists the build constraints to be satisfied by the further
|
|
imports of source packages.
|
|
|
|
For example the following custom build tag
|
|
|
|
// yaegi:tags noasm
|
|
|
|
Will ensure that an import of a package will exclude files containing
|
|
|
|
// +build !noasm
|
|
|
|
And include files containing
|
|
|
|
// +build noasm
