Chat #

Simple Vidya / egui LLM chat. API keys are loaded from OpenBao (openbao.boxd.sh, secret ai-api-keys) — no paste-into-settings flow for day-to-day use.

Assistant replies render as CommonMark (headings, lists, code fences) with LaTeX math ($…$, $$…$$, \(...\), \[...\]).

Run #

nix run                 # cargo build + gtk-launch uk.nandi.chat.desktop
nix develop             # interactive → cargo run

Needs sibling ../vidya.

OpenBao #

On launch the app reads KV v2 path secret/ai-api-keys.

Env / file Purpose
BAO_ADDR / VAULT_ADDR Server URL (default https://openbao.boxd.sh)
BAO_TOKEN / VAULT_TOKEN Auth token
~/.vault-token or ~/.bao-token Token file fallback

Known key fields → providers:

Secret field Provider
OPENROUTER_API_KEY OpenRouter (default when present; model list from API)
DEEPSEEK_API_KEY DeepSeek
OPENCODE_API_KEY OpenCode Zen
OLLAMA_API_KEY Ollama Cloud

Use #

  1. Ensure a token is available (env or ~/.bao-token).
  2. Start the app — status line shows loaded providers.
  3. Pick provider / model in the header.
  4. Type a message; Enter sends, Shift+Enter newline.
  5. New starts a fresh chat (current one stays on disk). Resume picks a past session. Clear wipes the view without deleting saved history.

Sessions #

Conversations are saved as JSON under $XDG_DATA_HOME/uk.nandi.chat/sessions (or ~/.local/share/uk.nandi.chat/sessions). Each file holds messages plus the provider/model used.

Android APK #

Phone package (uk.nandi.chat, aarch64). Same chat UI; paste an OpenBao token in-app when no ~/.bao-token is available (or adb push to /data/local/tmp/bao-token).

just apk-release          # → android/target/release/apk/chat.apk
just publish-apk          # → https://chat-apk.boxd.sh/chat.apk

Needs Android NDK (ANDROID_NDK_HOME, default ~/.local/share/android-ndk-r29), cargo-apk, and rustup target add aarch64-linux-android.

CI / Cachix #

On every push to main, GitHub Actions builds nix build .#chat and pushes store paths to codegod100.cachix.org (see .github/workflows/cachix.yml).

Required repository secret on codegod100/chat:

Secret Purpose
OPENBAO_TOKEN Read token for OpenBao; CI fetches CACHIX_AUTH_TOKEN from secret/data/cachix (and related KV paths), same as sleek

Set with: gh secret set OPENBAO_TOKEN -R codegod100/chat
