Involved Source Files Package plugin implements loading and symbol resolution of Go plugins. A plugin is a Go main package with exported functions and variables that has been built with: go build -buildmode=plugin When a plugin is first opened, the init functions of all packages not already part of the program are called. The main function is not run. A plugin is only initialized once, and cannot be closed. Currently plugins are only supported on Linux, FreeBSD, and macOS. Please report any issues. plugin_stubs.go
Package-Level Type Names (total 2)
/* sort by: | */
Plugin is a loaded Go plugin. Lookup searches for a symbol named symName in plugin p. A symbol is any exported variable or function. It reports an error if the symbol is not found. It is safe for concurrent use by multiple goroutines. func Open(path string) (*Plugin, error)
A Symbol is a pointer to a variable or function. For example, a plugin defined as package main import "fmt" var V int func F() { fmt.Printf("Hello, number %d\n", V) } may be loaded with the Open function and then the exported package symbols V and F can be accessed p, err := plugin.Open("") if err != nil { panic(err) } v, err := p.Lookup("V") if err != nil { panic(err) } f, err := p.Lookup("F") if err != nil { panic(err) } *v.(*int) = 7 f.(func())() // prints "Hello, number 7" func (*Plugin).Lookup(symName string) (Symbol, error)
Package-Level Functions (only one)
Open opens a Go plugin. If a path has already been opened, then the existing *Plugin is returned. It is safe for concurrent use by multiple goroutines.
