# POSIX sh / Dash Integration

To make interacting with the STT (Speech-to-Text) CLI easier, you can add a shortcut function to your shell profile. This allows you to simply type `s "your question"` in the terminal.

> **Note:** Dash and other strict POSIX shells (`/bin/sh` on Debian/Ubuntu is Dash by default) do **not** support the `local` keyword in all contexts, process substitution, or arrays. The function below is written to be fully POSIX-compatible.

## Setup Instructions

1. Open your shell profile with an editor you like:
   ```sh
   nano ~/.profile
   # or, if your system uses ~/.shrc for interactive shells:
   nano ~/.shrc
   ```

2. Paste the following block at the end of the file:

```sh

unalias s 2>/dev/null
s() {
    if [ $# -eq 0 ]; then
        echo "question <your question>"
        return 1
    fi
    update_github_ip
    TEMP_FILE=$(mktemp)
    SHORT_TIMEOUT_SECONDS=2
    LONG_TIMEOUT_SECONDS=70
    # Path shortcuts
    PY_EXEC="$SL5NET_AURA_PROJECT_ROOT/.venv/bin/python3"
    CLI_SCRIPT="$SL5NET_AURA_PROJECT_ROOT/scripts/py/cli_client.py"
    # --- 1. try
    timeout "$SHORT_TIMEOUT_SECONDS" \
    "$PY_EXEC" -u "$CLI_SCRIPT" "$@" \
    --lang "de-DE" --unmasked < /dev/null > "$TEMP_FILE" 2>&1
    EXIT_CODE=$?
    OUTPUT=$(cat "$TEMP_FILE")
    rm "$TEMP_FILE"
    if echo "$OUTPUT" | grep -q "Verbindungsfehler" || ! pgrep -f "streamlit-chat.py" > /dev/null; then
        echo "Service-Check: Backend oder Frontend fehlt. Starte neu..."
        start_service
        echo '++++++++++++++++++++++++++++++++++++++++++++++++++'
        KIWIX_SCRIPT="$SL5NET_AURA_PROJECT_ROOT/config/maps/plugins/standard_actions/wikipedia_local/de-DE/kiwix-docker-start-if-not-running.sh"
        if [ -f "$KIWIX_SCRIPT" ]; then
            sh "$KIWIX_SCRIPT"
        fi
        echo '++++++++++++++++++++++++++++++++++++++++++++++++++'
        echo "BITTE ERNEUT EINGEBEN: s $*"
        return 1
    # 2. Timeout (124) OR success (0)
    elif [ "$EXIT_CODE" -eq 124 ] || [ "$EXIT_CODE" -eq 0 ]; then
        if [ "$EXIT_CODE" -eq 0 ]; then
            echo "$OUTPUT"
            return 0
        fi
        echo "answer > $SHORT_TIMEOUT_SECONDS sec. set Timeout= $LONG_TIMEOUT_SECONDS s..."
        TEMP_FILE_2=$(mktemp)
        timeout "$LONG_TIMEOUT_SECONDS" \
        "$PY_EXEC" -u "$CLI_SCRIPT" "$@" \
        --lang "de-DE" --unmasked < /dev/null > "$TEMP_FILE_2" 2>&1
        EXIT_CODE_2=$?
        OUTPUT_2=$(cat "$TEMP_FILE_2")
        rm "$TEMP_FILE_2"
        echo "$OUTPUT_2"
        if [ "$EXIT_CODE_2" -ne 0 ]; then
            echo "WARNUNG: Timeout > $LONG_TIMEOUT_SECONDS Sec. "
        fi
        return 0
    else
        echo "ERROR"
        echo "$OUTPUT"
        return $EXIT_CODE
    fi
}
```

3. Reload your configuration:
   ```sh
   . ~/.profile
   ```

## POSIX / Dash-Specific Notes

- `local` is **not** used here for maximum compatibility. All variables are function-scoped by convention only; they are technically global in strict POSIX sh.
- `$@` is preferred over `$*` when passing arguments to commands, to preserve proper word splitting with quoted arguments.
- `bash` is replaced with `sh` when executing the Kiwix helper script to stay within the POSIX toolchain.
- This configuration file is best placed in `~/.profile`, which is sourced by login shells. For interactive non-login shells, your distribution may use `~/.shrc` — check your system documentation.

## Features

- **Dynamic Paths**: Automatically finds the project root via the `/tmp` marker file.
- **Auto-Restart**: If the backend is down, it attempts to run `start_service` and local Wikipedia services.
- **Smart Timeouts**: Tries a quick 2-second response first, then falls back to a 70-second deep processing mode.
