Functions ¶

func CleanPath ¶

func CleanPath(path string) string

CleanPath returns the normalized version of a path that can be used as an identifier.

func Paths ¶

func Paths(path string, recurse bool) (paths []string, err error)

Paths returns a sorted list of files contained at path. If recurse is true and path is a directory, then Paths will walk the directory structure recursively and list files at each level.

func SplitPrefix ¶

func SplitPrefix(path string) ([]string, string)

SplitPrefix returns a tuple specifying the document prefix and the file path.

Types ¶

type Filter ¶

type Filter func(abspath string, info os.FileInfo, depth int) bool

Filter defines the interface for filtering files during loading. If the filter returns true, the file should be excluded from the result.

func GlobExcludeName ¶

func GlobExcludeName(pattern string, minDepth int) Filter

GlobExcludeName excludes files and directories whose names do not match the shell style pattern at minDepth or greater.

type RegoFile ¶

type RegoFile struct {
	Name   string
	Parsed *ast.Module
	Raw    []byte
}

RegoFile represents the result of loading a single Rego source file.

func Rego ¶

func Rego(path string) (*RegoFile, error)

Rego returns a RegoFile object loaded from the given path.

type Result ¶

type Result struct {
	Documents map[string]interface{}
	Modules   map[string]*RegoFile
	// contains filtered or unexported fields
}

Result represents the result of successfully loading zero or more files.

func All ¶

func All(paths []string) (*Result, error)

All returns a Result object loaded (recursively) from the specified paths.

func AllRegos ¶

func AllRegos(paths []string) (*Result, error)

AllRegos returns a Result object loaded (recursively) with all Rego source files from the specified paths.

func Filtered ¶

func Filtered(paths []string, filter Filter) (*Result, error)

Filtered returns a Result object loaded (recursively) from the specified paths while applying the given filters. If any filter returns true, the file/directory is excluded.
