Types

type Parser

type Parser struct {
	// ExecRoot is the exec root under which all file paths are relative.
	ExecRoot string
	// DigestStore is a store for file digests as read from disk.
	DigestStore filemetadata.Cache
}

Parser parses dependency files into manifests.

func (*Parser) GetDeps

func (p *Parser) GetDeps(dFilePath string) (string, error)

GetDeps returns the deps file content based on the d file and include directories. The deps are formatted as sorted unique "<path>:<digest>\n" lines. If <digest> is "NA", it means it failed to get digest of the file.

func (*Parser) VerifyDepsFile

func (p *Parser) VerifyDepsFile(dFilePath string, rec *logger.LogRecord) (bool, error)

VerifyDepsFile compares an existing deps file in the expected <path>.d.deps path to the one that would be generated from the provided d file and include directories.

func (*Parser) WriteDepsFile

func (p *Parser) WriteDepsFile(dFilePath string, rec *logger.LogRecord) error

WriteDepsFile creates a deps file from the provided d file and include directories. The path of the deps file is the same as the provided d file, with the .deps extension.
