ellmercodex v0.2.0

Cambios importantes

• La autenticación y el transporte ahora siguen el flujo documentado por OpenAI "Sign in with ChatGPT" para apps de código abierto que se ejecutan localmente. El paquete ya no reutiliza el cliente OAuth del CLI de Codex ni usa los endpoints no documentados de chatgpt.com/backend-api/codex.
• Hay que volver a iniciar sesión con codex_login(). Las credenciales anteriores no se migran.
• El primer login registra la app con tu cuenta y espacio de trabajo de ChatGPT; los siguientes reutilizan ese registro. Para cambiar de cuenta, usa codex_logout() y vuelve a iniciar sesión.
• El callback pasó a http://127.0.0.1:1455/callback (configurable con ELLMERCODEX_CALLBACK_PORT).
• Las credenciales se guardan en tools::R_user_dir("ellmercodex", "config") (o en ELLMERCODEX_HOME) con permisos solo para tu usuario. HTTR2_OAUTH_CACHE ya no se usa.
• codex_logout() revoca el token en OpenAI antes de borrar la credencial local.
• Los chats y codex_models() usan la API pública https://api.openai.com/v1. El argumento client_version de codex_models() queda obsoleto y se ignora.
• Por los límites de la vista previa de OpenAI, temperature, top_p, max_tokens, metadata, previous_response_id y otros argumentos excluidos fallan antes de enviar la solicitud. Una respuesta response.incomplete ahora es un error (codex_incomplete_error).
• Los errores del plan tienen condiciones propias, por ejemplo codex_usage_limit_error cuando se alcanza el límite de uso.
• El título del paquete ahora es "'ChatGPT' Plan Provider for 'ellmer'".

Verificación

• R CMD check --as-cran local: 0 errores, 0 advertencias; solo la nota de "New submission".
• win-builder (Windows, R-devel): solo la nota de "New submission".
• GitHub Actions: Linux, Windows y macOS con ellmer mínimo y último aprobados.
• Prueba en vivo con una cuenta real: login, catálogo de modelos, chat, streaming, herramientas, salida estructurada, imágenes, esfuerzo de razonamiento y renovación del token.

ellmercodex v0.1.64

Cambios

• Permite pasar IDs de modelos explícitos aunque no aparezcan todavía en el catálogo de la cuenta. El servicio valida acceso y esfuerzo de razonamiento.
• codex_models() sigue mostrando el catálogo remoto real, sin filas GPT-6 inventadas.
• Incluye comprobaciones en vivo opt-in para gpt-6-astra, gpt-6-sol y gpt-6-luna.

Verificación

• R CMD check --as-cran: 0 errores, advertencias ni notas.
• GitHub Actions: matrices latest y minimum aprobadas.

ellmercodex v0.1.63

Highlights

• Supports ellmer 0.5.0 and later through a Model/Provider adapter with runtime checks for the Chat contracts this integration needs. Unsupported provider token counting and file management fail clearly before a request.
• Documents a single-process Linux VM deployment that retains OAuth credentials across restarts using httr2 1.3.0 or later and a persistent cache volume.
• Adds offline cache lifecycle coverage and CI checks for both the minimum and latest supported ellmer versions.

See NEWS.md for details.

ellmercodex v0.1.62

Highlights

• Removed obsolete private OAuth callback/PKCE code.
• Removed legacy ellmer structured-stream repair helpers superseded by the httr2 and ellmer compatibility paths.
• Updated tests and internal documentation; no public API behavior changes.

See NEWS.md for the full changelog.

ellmercodex v0.1.61

Replaced the macOS/OS-keyring credential backend with httr2's encrypted OAuth cache. Cached credentials are stored under the user-level ellmercodex cache and refreshed without Keychain prompts.

Also includes streamed reasoning-summary fixes, account-backed model discovery and reasoning-effort validation, improved usage handling, expanded compatibility coverage, and updated authentication documentation.

ellmercodex v0.1.6

Highlights:

• Selects the default model from the authenticated account catalog and validates advertised reasoning effort.
• Preserves omitted usage values as unknown and consolidates tool execution in the version-gated compatibility layer.
• Expands opt-in live acceptance coverage and documents the remaining undocumented transport risk; no Codex CLI runtime dependency is introduced.

ellmercodex v0.1.5

Fixed Codex Responses streaming history duplication by correlating streamed text deltas with provider item IDs and merging completed message items once. Preserved terminal-only message output and removed duplicate message content from rich content streaming. Added regression coverage and a full maintainer verification runner for offline and live chat, streaming, structured, async, tool, cancellation, multimodal, and model-discovery workflows.

ellmercodex v0.1.4

Highlights

• Expanded public API documentation, conditions, side effects, return values, and compatibility boundaries.
• Improved the getting-started vignette and package guidance.
• Included the ellmer compatibility and streaming-test updates.

Validation

• GitHub R-CMD-check: passed.
• Local R CMD check --as-cran --no-manual: 0 errors, 0 warnings, 1 expected “New submission” NOTE.

The attached tarball is the CRAN-style source package.

ellmercodex v0.1.3

ellmercodex v0.1.3 is an experimental prerelease targeting ellmer 0.4.2 exactly.

Highlights:

• One version-gated compatibility seam backed by ellmer's Chat lifecycle.
• Public Chat methods for normal, streaming, async, structured, rich-content, tool-calling, cancellation, cloning, history, echo, usage, cost, duration, and finish metadata.
• Clone-safe credentials with refresh-token rotation and persistent updates across request paths.
• Ordered conversion of text, tool calls, images, PDFs, reasoning, terminal output, and unknown content.

Known blockers:

• ellmer parallel/batch helpers are explicitly unavailable because the Codex subscription transport is stream-only and has no compatible OpenAI Batch API.
• The transport is undocumented and uses an isolated private ellmer compatibility seam.
• The full regression suite, R CMD check, and live API checks were not run for this release.

This release must not be treated as stable. See docs/ellmer-chat-interface.md for the complete capability matrix and follow-up commands.

ellmercodex v0.1.2

Release v0.1.2 adds asynchronous Chat methods, async tool modes and callbacks, cancellation-controller support, and image/PDF content preservation while retaining the Codex compatibility layer's experimental status. Known gaps are documented in the README: exact echo="all" semantics, full streamed/tool metadata, rich output inside the custom tool loop, batch/parallel helpers, and provider-native tools.
