# Manual setup
These instructions describe how to install and run the bridge manually from a clone of this repository.

## Minimum requirements
* Python 3.8
* Node 16.13 (not yet tested with earlier versions)
* postgresql 11 or sqlite3
* A KakaoTalk account on a smartphone (Android or iOS)

## Optional requirements
* Native dependencies for [end-to-bridge](https://docs.mau.fi/bridges/general/end-to-bridge-encryption.html): https://docs.mau.fi/bridges/python/optional-dependencies.html#all-python-bridges

## Initial setup

### node-kakao module
1. `cd` to the `node` directory and run `npm install`
1. Copy `node/example-config.json` to `node/config.json`
1. Edit `node/config.json` with desired settings (see [node/README.md](node/README.md) for details)

### Bridge module
1. `cd` to the repository root and create a Python virtual environment with `python3 -m venv .venv`, and enter it with `source .venv/bin/activate`
1. Install Python requirements:
    * `pip install -Ur requirements.txt` for base functionality
    * `pip install -Ur optional-requirements.txt` for [end-to-bridge](https://docs.mau.fi/bridges/general/end-to-bridge-encryption.html) encryption and metrics
        * Note that end-to-bridge encryption requires some native dependencies. For details, see https://docs.mau.fi/bridges/python/optional-dependencies.html#all-python-bridges
1. Copy `matrix_appservice_kakaotalk/example-config.yaml` to `config.yaml`, and update it with the proper settings to connect to your homeserver
    * In particular, be sure to set the `rpc.connection` settings to use the socket you chose in `node/config.json`
    * If using Postgres as your database, create a new database that can be accessed via the URI you set for it in `appservice.database`
1. Run `python -m matrix_appservice_kakaotalk -g` to generate an appservice registration file, and update your homeserver configuration to accept it

## Running manually
1. In the `node` directory, launch the node-kakao module with `node src/main.js`
1. In the project root directory, run the bridge module with `python -m matrix_appservice_kakaotalk`
1. Start a chat with the bot and use the `login <email>` command to sync your KakaoTalk account
    * Note that on first use, you must enter a verification code on a smartphone version of KakaoTalk in order for the login to complete

## systemd
The [systemd](systemd) directory provides sample service unit configuration files for running the bridge & node-kakao modules:

* `matrix-appservice-kakao.service` for the bridge module
* `matrix-appservice-kakao-node.service` for the node-kakao module

To use them as-is, follow these steps after [initial setup](#initial-setup):

1. Place/link your clone of this repository in `/opt/matrix-appservice-kakaotalk`
    * If moving your repo directory after having already created a Python virtual environment for the bridge module, re-create the virtual environment after moving to ensure its paths are up-to-date
    * Alternatively, clone it to `/opt/matrix-appservice-kakaotalk` in the first place
1. Install the services as either system or user units
    * To install as system units:
        1. Copy/link the service files to a directory in the system unit search path, such as `/etc/systemd/system/`
        1. Create the services' configuration directory with `sudo mkdir /etc/matrix-appservice-kakaotalk`
        1. RECOMMENDED: Create the `matrix-appservice-kakaotalk` user on your system with `adduser` or an equivalent command, then uncomment the `User` and `Group` lines in the service files
            * If creating this user, also give it write permissions on the services' configuration directory with `chgrp matrix-appservice-kakaotalk /etc/matrix-appservice-kakaotalk && chmod g+w /etc/matrix-appservice-kakaotalk`
    * To install as user units:
        1. Copy/link the service files to a directory in the user unit search path, such as `~/.config/systemd/user`
        1. Create the services' configuration directory with `mkdir $XDG_CONFIG_HOME/matrix-appservice-kakaotalk`
1. Copy/link the bridge & node-kakao module configuration files to the services' configuration directory as `config.yaml` and `node-config.json`, respectively
1. Start the services now and on every boot boot with `[sudo] systemd [--user] enable --now matrix-appservice-kakaotalk{,-node}`

## Upgrading
Simply `git pull` or `git rebase` the latest changes and rerun any installation commands (`npm install`, `pip install -Ur ...`).
