Pi integration

This package registers a custom repling provider for Pi.

What to use

The extension registers:

• provider: repling
• models such as repling-gpt-5.3-codex, repling-gpt-5.2-codex, and repling-gpt-5.1-codex
• compatibility model: bridge

Quick start from Pi

Install the published package:

pi install npm:@pfeodrippe/repling-pi

After that, start Pi with:

pi --provider repling --model repling-gpt-5.3-codex

You can also start pi normally and choose a repling/... model from /model or Ctrl+L. The selected Pi model is passed through to Repling.

By default the extension uses Pi's own openai-codex auth. If you have not logged in yet, start pi, run /login inside the TUI, and choose the ChatGPT/Codex auth option. The extension resolves that token from Pi and passes it to the Repling bridge through child-process environment variables. You do not need a separate bridge API key for the default path.

Useful flags

• --repling-bridge-provider openai-codex (default, uses Pi /login auth)
• --repling-bridge-provider openai-responses (OpenAI Platform API)
• --repling-bridge-provider codex-cli (raw text/debug path only)
• --repling-bridge-provider pi-openai-codex (raw text/debug path only)
• --repling-bridge-model gpt-5.3-codex
• --repling-bridge-path /absolute/path/to/repling-pi-bridge.mjs
• --repling-project-dir /absolute/path
• --repling-sessions-root /absolute/path
• --repling-system-prompt "You are terse."
• --repling-compaction-tool project.compaction/compact
• --repling-load-project-tools
• --repling-repl-deps (enable Clojure 1.12 runtime dependency loading)
• --repling-auto-compaction
• --repling-timeout-ms 60000
• --repling-max-retries 1
• --repling-retry-delay-ms 1000
• --repling-endpoint https://...
• --repling-api-key ...
• --repling-api-key-env MY_KEY_ENV

Useful TUI commands

• /repling-state
• /repling-model <provider> <model>
• /repling-repl-deps on
• /repling-repl-deps off
• /repling-reset

/repling-repl-deps on|off is persisted per project cwd in Pi's agent config directory and mirrored into the current Pi session, so later Pi runs in the same folder reuse the setting. The startup flag --repling-repl-deps still enables it for that process even if no persisted project setting exists yet.

The extension defaults to a short retry profile (--repling-max-retries 1, --repling-retry-delay-ms 1000) so interactive Pi sessions fail fast instead of appearing hung behind long provider retry loops.

Session behavior

The extension does not restore old Repling bridge sessions automatically and does not inject prior Pi transcript messages into new Repling prompts. It only uses Pi session files for the current project to populate editor prompt history, so previous user messages are selectable with editor history navigation without becoming model context.

Slash commands

• /repling-help
• /repling-state
• /repling-reset
• /repling-model <provider> <model>
• /repling-repl-deps on
• /repling-repl-deps off

Normally you should use Pi's /model picker for model selection. /repling-model remains available for overriding the lower-level bridge provider manually.
