package strvals

import "github.com/open-policy-agent/opa/internal/strvals"

Package strvals provides tools for working with strval lines.

OPA runtime config supports a compressed format for YAML settings which we call strvals. The format is roughly like this:

name=value,topname.subname=value

The above is equivalent to the YAML document

name: value
topname:
  subname: value

This package provides a parser and utilities for converting the strvals format to other formats.

Constants ¶

const MaxIndex = 65536

MaxIndex is the maximum index that will be allowed by setIndex. The default value 65536 = 1024 * 64

Variables ¶

var ErrNotList = errors.New("not a list")

ErrNotList indicates that a non-list was treated as a list.

Functions ¶

func Parse ¶

func Parse(s string) (map[string]interface{}, error)

Parse parses a set line.

A set line is of the form name1=value1,name2=value2

func ParseInto ¶

func ParseInto(s string, dest map[string]interface{}) error

ParseInto parses a strvals line and merges the result into dest.

If the strval string has a key that exists in dest, it overwrites the dest version.

func ParseIntoFile ¶

func ParseIntoFile(s string, dest map[string]interface{}, runesToVal runesToVal) error

ParseIntoFile parses a filevals line and merges the result into dest.

This method always returns a string as the value.

func ParseIntoString ¶

func ParseIntoString(s string, dest map[string]interface{}) error

ParseIntoString parses a strvals line and merges the result into dest.

This method always returns a string as the value.

func ParseString ¶

func ParseString(s string) (map[string]interface{}, error)

ParseString parses a set line and forces a string value.

A set line is of the form name1=value1,name2=value2

func ToYAML ¶

func ToYAML(s string) (string, error)

ToYAML takes a string of arguments and converts to a YAML document.
