Functions

func CreateBBMainSource

func CreateBBMainSource(fset *token.FileSet, files []*ast.File, pkgs []string, destDir string) error

CreateBBMainSource creates a bb Go command main.go that imports all given pkgs and writes the command to destDir.

fset and files must be parsed bb template main.go, usually ./bbmain/cmd/main.go.

func ParseAST

func ParseAST(name string, files []string) (*token.FileSet, []*ast.File, []string, error)

ParseAST parses the given files for a package named name.

Only files with a matching package statement will be part of the AST returned.

func WritePkg

func WritePkg(p *packages.Package, destDir string) error

WritePkg writes p's files into destDir.

Types

type Package

type Package struct {
	// Name is the executable command name.
	//
	// In the standard Go tool chain, this is usually the base name of the
	// directory containing its source files.
	Name string

	// Pkg is the actual data about the package.
	Pkg *packages.Package
	// contains filtered or unexported fields
}

Package is a Go package.

func NewPackage

func NewPackage(name string, p *packages.Package) *Package

NewPackage creates a new Package based on an existing packages.Package.

func (*Package) PackageName

func (p *Package) PackageName() string

PackageName is teh name of the rewritten Go package.

func (*Package) Rewrite

func (p *Package) Rewrite(destDir, bbImportPath string) error

Rewrite rewrites p into destDir as a bb package, rewriting its init and main functions.

bbImportPath is the importpath to use for bbmain. bbImportPath is usually bb.u-root.com/bb/pkg/bbmain for the Go module/vendor-based compilations, but github.com/u-root/gobusybox/src/pkg/bb/bbmain for bazel-based compilations.
