pex

Documentation

Overview

Package pex implements construction of .pex files in Go. For performance reasons we've ultimately abandoned doing this in Python; we were ultimately not using pex for much at construction time and we already have most of what we need in Go via jarcat.

Types

type BuildProperties

type BuildProperties struct {
	Class    string `json:"class"`
	Platform string `json:"platform"`
	Version  []int  `json:"version"`
}

A BuildProperties represents the BuildProperties entry in a Info.

type Info

type Info struct {
	BuildProperties BuildProperties `json:"build_properties"`
	CodeHash        string          `json:"code_hash"`
	EntryPoint      string          `json:"entry_point"`
	ZipSafe         bool            `json:"zip_safe"`
	PexRoot         string          `json:"pex_root"`
}

A Info describes the PEX-INFO file written into the root of the .zip file.

type Writer

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

A Writer implements writing a .pex file in various steps.

func NewWriter

func NewWriter(entryPoint, interpreter, codeHash string, zipSafe bool) *Writer

NewWriter constructs a new Writer.

func (*Writer) SetShebang

func (pw *Writer) SetShebang(shebang string)

SetShebang sets the leading shebang that will be written to the file.

func (*Writer) SetTest

func (pw *Writer) SetTest(srcs []string)

SetTest sets this Writer to write tests using the given sources. This overrides the entry point given earlier.

func (*Writer) Write

func (pw *Writer) Write(out, moduleDir string) error

Write writes the pex to the given output file.
