Changelog

All notable changes to atex will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.7.1 - 2026-02-06

Included Com.Atproto.* lexicon modules have been removed and put into atex_atproto instead.

The PLC directory used for identity resolution can now be configured. See Atex.Config.IdentityResolve for more information. (Thanks @hexmani.ac!)
Add an extra optional opts parameter to some Atex.OAuth functions, to allow for better integration with other ecosystems. (Thanks @lekkice.moe!)

Atex.OAuth.Plug now raises Atex.OAuth.Error exceptions instead of handling error situations internally. Applications should implement Plug.ErrorHandler to catch and gracefully handle them.
Atex.OAuth.Plug now saves only the user's DID in the session instead of the entire OAuth session object. Applications must use Atex.OAuth.SessionStore to manage OAuth sessions.
Atex.XRPC.OAuthClient has been overhauled to use Atex.OAuth.SessionStore for retrieving and managing OAuth sessions, making it easier to use with not needing to manually keep a Plug session in sync.

Atex.OAuth.SessionStore behaviour and Atex.OAuth.Session struct for managing OAuth sessions with pluggable storage backends.
- Atex.OAuth.SessionStore.ETS - in-memory session store implementation.
- Atex.OAuth.SessionStore.DETS - persistent disk-based session store implementation.
Atex.OAuth.Plug now requires a :callback option that is a MFA tuple (Module, Function, Args), denoting a callback function to be invoked by after a successful OAuth login. See the OAuth example for a simple usage of this.
Atex.OAuth.Permission module for creating AT Protocol permission strings for OAuth.
Atex.OAuth.Error exception module for OAuth flow errors. Contains both a human-readable message string and a machine-readable reason atom for error handling.
Atex.OAuth.Cache module provides TTL caching for OAuth authorization server metadata with a 1-hour default TTL to reduce load on third-party PDSs.
Atex.OAuth.get_authorization_server/2 and Atex.OAuth.get_authorization_server_metadata/2 now support an optional fresh parameter to bypass the cache when needed.

mix atex.lexicons now adds @moduledoc false to generated modules to stop them from automatically cluttering documentation.
Atex.IdentityResolver.Cache.ETS now uses ConCache instead of ETS directly, with a 1-hour TTL for cached identity information.

deflexicon now converts all def names to be in snake_case instead of the casing as written the lexicon.

deflexicon now emits structs for records, objects, queries, and procedures.
Atex.XRPC.get/3 and Atex.XRPC.post/3 now support having a lexicon struct as the second argument instead of the method's name, making it easier to have properly checked XRPC calls.
Add pre-transpiled modules for the core com.atproto lexicons.

Remove Atex.HTTP and associated modules as the abstraction caused a bit too much complexities for how early atex is. It may come back in the future as something more fleshed out once we're more stable.
Rename Atex.XRPC.Client to Atex.XRPC.LoginClient

Atex.OAuth module with utilites for handling some OAuth functionality.
Atex.OAuth.Plug module (if Plug is loaded) which provides a basic but complete OAuth flow, including storing the tokens in Plug.Session.
Atex.XRPC.Client behaviour for implementing custom client variants.
Atex.XRPC now supports using different client implementations.
Atex.XRPC.OAuthClient to make XRPC calls on the behalf of a user who has authenticated with ATProto OAuth.

Atex.Lexicon module that provides the deflexicon macro, taking in a JSON Lexicon definition and converts it into a series of schemas for each definition within it.
mix atex.lexicons for converting lexicon JSON files into modules using deflexicon easily.

Atex.HTTP module that delegates to the currently configured adapter.
Atex.HTTP.Response struct to be returned by Atex.HTTP.Adapter.
Atex.IdentityResolver module for resolving and validating an identity, either by DID or a handle.
- Also has a pluggable cache (with a default ETS implementation) for keeping some data locally.

Atex.TID module for manipulating ATProto TIDs.
Atex.Base32Sortable module for encoding/decoding numbers as base32-sortable strings.
Basic XRPC client.
