Types

type Log

type Log struct {
	EnableDebug bool
	Output      io.Writer
}

Log provides an implementation of Logger.

func (Log) Debug

func (l Log) Debug(msg string)

func (Log) Info

func (l Log) Info(msg string)

type Logger

type Logger interface {
	Info(message string)
	Debug(message string)
}

Logger is an interface that presents only two main logging methods, Info and Debug.

type Mere

type Mere struct {
	// contains filtered or unexported fields
}

func NewMere

func NewMere(log Logger, store string) (Mere, error)

type Package

type Package struct {
	Name  string   `json:"name"`
	Deps  []string `json:"deps,omitempty"`
	Files []string `json:"files,omitempty"`
	Libs  []string `json:"libs,omitempty"`
}

Package defines the properties needed to create an individual package.

type Source

type Source struct {
	URL       string `json:"url"`
	B3Sum     string `json:"b3sum"               jsonschema:"minLength=64,maxLength=64"`
	LocalName string `json:"localName,omitempty"`
	// contains filtered or unexported fields
}

Source defines the properties needed to retrieve and validate a source file.

type Spec

type Spec struct {
	Name        string    `json:"name"`
	Description string    `json:"description"`
	Home        string    `json:"home"`
	Version     string    `json:"version"`
	Release     int64     `json:"release"`
	Sources     []Source  `json:"sources,omitempty"`
	BuildDeps   string    `json:"buildDeps,omitempty"`
	Build       string    `json:"build,omitempty"`
	Test        string    `json:"test,omitempty"`
	Install     string    `json:"install,omitempty"`
	Packages    []Package `json:"packages"`
	// contains filtered or unexported fields
}

Spec contains the properties needed to build one or more packages from the same source code.

func NewSpec

func NewSpec(path string, output io.Writer) (*Spec, error)

NewSpec constructs and validates new Spec structs from a given file.

func (*Spec) BuildSteps

func (s *Spec) BuildSteps() error

BuildSteps executes the build, test and install steps as defined in a package spec.

func (*Spec) Cleanup

func (s *Spec) Cleanup()

Cleanup removes the entire internal working directory.
