Basic example

This example demonstrates how to parse a turtle string into an AclDoc object, then modify the permissions for a specific user and finally parse it back to turtle.

const SolidAclParser = require('SolicAclParser')

const webId = 'https://pod.example.org/profile/card#me'
const aclUrl = 'https://pod.example.org/private/file.ext.acl'
const fileUrl = 'https://pod.example.org/private/file.ext'
const turtle = `
@prefix   acl:  <http://www.w3.org/ns/auth/acl#>.
@prefix  foaf:  <http://xmlns.com/foaf/0.1/>.

<#Read-0>
    a               acl:Authorization;
    acl:agentClass  foaf:Agent;                               # everyone
    acl:mode        acl:Read;                                 # has Read-only access
    acl:accessTo    <https://pod.example.org/private/file.ext>.`

const { AclParser, Permissions } = SolidAclParser
const { WRITE, CONTROL } = Permissions

async function main() {
  // Parse the turtle to an AclDoc object which we can modify
  const parser = new AclParser({ aclUrl, fileUrl })
  const doc = await parser.turtleToAclDoc(turtle)

  // Give the webId WRITE and CONTROL permissions
  doc.addRule([WRITE, CONTROL], webId)

  // Parse it back to turtle so we can store it in the pod
  const newTurtle = await parser.aclDocToTurtle(doc)
  console.log(newTurtle)
}
main()

Output turtle

@prefix acl: <http://www.w3.org/ns/auth/acl#>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.

<#Read-0> a acl:Authorization;
    acl:agentClass foaf:Agent;
    acl:accessTo <./file.ext>;
    acl:mode acl:Read.
<#WriteControl-0> a acl:Authorization;
    acl:agent </profile/card#me>;
    acl:accessTo <./file.ext>;
    acl:mode acl:Write, acl:Control.
