# Computer bot
Now, GitHub contains mirror, original is [here](https://gitdab.com/er2/comp-tg).
This bot is a reborn of [this](https://github.com/Er2pkg/computer) bot,
but on Telegram.
Bot uses an OOP-style of lua
as [described on Wikipedia](https://is.gd/f0Vadk)
Also, bot automatically detects language installed in the client.
TODO: Rewrite core to C, [lua have C API](https://www.lua.org/manual/5.3/manual.html#4)
and C is faster.
# Installation
[Alpine Linux](https://alpinelinux.org), root:
* Enable community repo (in wiki)
* Install: `apk add sudo git lua5.3 luarocks openssl-dev`
* Install dependencies: `luarocks-5.3 install luasec`
* Create user: `adduser user`
setup sudo and login to user
* Get repo: `git clone https://github.com/Er2ch/comp-tg`
and `cd comp-tg`
* Change token and owner in `config.lua`
TODO: Use env instaed of config
* Run: `lua5.3 init.lua`

* Computer bot
Now, GitHub contains *mirror*, original is *[[https://gitdab.com/er2/comp-tg][here]]*.
-----
This bot is a continue of [[https://github.com/Er2pkg/computer][my Discord bot]],
but on Telegram.
Bot uses an OOP-style of Lua
as [[https://is.gd/f0Vadk][described on Wikipedia]].
Also bot reads client language and automatically loads needing locale.
Maybe I rewrite bot's core to C but there already so many Lua code.
* Installation
[[https://alpinelinux.org][Alpine linux]], root:
