# TelegramBotAPI changelog
## 0.14.0
* Now library have no default engine for both webhooks and requests executor. It is required for clients to set
some default library
* All proxy help methods was removed . They are will be replaced in separated project
* `Ktor` version `1.1.3` -> `1.1.4`
* Requests results now always decoding as `UTF-8`
* `AbstractRequestCallFactory` was added with cache of methods urls to avoid memory leaks
* Small refactoring of work with response in `KtorRequestsExecutor`
* Kotlin version `1.3.30` -> `1.3.31`
* Kotlin coroutines `1.2.0` -> `1.2.1`
* `CommonForwardedMessage` was renamed to `UserForwardedMessage`
* All forwarded messages are now just childs of `ForwardedMessage`:
* `AnonymousForwardedMessage` - for messages without forwarded info
* `UserForwardedMessage` - for messages from users and groups (contains not message id)
* `ForwardedFromChannelMessage` - for messages from channels
* Changed logic of forwarded messages preparing
## 0.13.0 Telegram Polls
* Type `PollOption` and `AnonymousPollOption` added

## How to work with library?
By default in any documentation will be meaning that you have variable in scope with names
For now, this library have no some API god-object. Instead of this, this library has several
important objects:
| Name of variable | Description | Where to get? (Examples) |
|:----------------:|:-----------:|:------------------------:|
| executor | [RequestsExecutor](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/bot/RequestsExecutor.kt) | [Ktor RequestExecutor realisation](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/bot/Ktor/KtorRequestsExecutor.kt) |
* [RequestsExecutor](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/bot/RequestsExecutor.kt)
* [Requests](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/requests)
* [Types](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/types)
## Requests Examples
### Types
### Get Me
Types declare different objects representation. For example, `Chat` for now represented as
interface and has several realisations:
* PrivateChat
* GroupChat
* SupergroupChat
* ChannelChat
Instead of common garbage with all information as in original [Chat](https://core.telegram.org/bots/api#chat),
here it was separated for more obvious difference between chats types and their possible content.
The same principle work with a lot of others things in this Telegram bot API.
### Requests
Requests usually are very simple objects, but some of them are using their own
build factories. For example, the next code show, how to get information about bot:
```kotlin
executor.execute(GetMe())
val requestsExecutor: RequestsExecutor = ...
requestsExecutor.execute(GetMe())
```
The result type of [GetMe](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/requests/GetMe) request is
[User](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/types/User). In fact, in this result must contain
`isBot` equal to `true` always.
### RequestsExecutor
It is base object which can be used to execute requests in API. For now by default included Ktor
realisation of `RequestsExecutor`, but it is possible, that in future it will be extracted in separated
project. How to create `RequestsExecutor`:
```kotlin
val requestsExecutor = KtorRequestsExecutor(TOKEN)
```
As a result you will receive `User` object. This object used as is now (as in API documentation), but it is possible
that this class will be renamed to `RawUser` and you will be able to get real realisation of this object like `Bot` (in
cases when `isBot` == `true`) or `User` (otherwise)
Here `KtorRequestsExecutor` - default realisation with Ktor. `TOKEN` is just a token of bot which was retrieved
according to [instruction](https://core.telegram.org/bots#3-how-do-i-create-a-bot).
Besides, for correct usage of this, you must implement in your project both one of engines for client and server
Ktor libraries:
```groovy
dependencies {
// ...
implementation "io.ktor:ktor-server-cio:$ktor_version"
implementation "io.ktor:ktor-client-okhttp:$ktor_version"
// ...
}
```
It is able to avoid using of `server` dependency in case if will not be used `Webhook`s. In this case,
dependencies list will be simplify:
```groovy
dependencies {
// ...
implementation "io.ktor:ktor-client-okhttp:$ktor_version"
// ...
}
```
Here was used `okhttp` realisation of client, but there are several others engines for Ktor. More information
available on ktor.io site for [client](https://ktor.io/clients/http-client/engines.html) and [server](https://ktor.io/quickstart/artifacts.html)
engines.
## Getting updates
@ -95,3 +154,22 @@ Template for Nginx server config you can find in [this gist](https://gist.github
For webhook you can provide `File` with public part of certificate, `URL` where bot will be available and inner `PORT` which
will be used to start receiving of updates. Actually, you can skip passing of `File` when you have something like
nginx for proxy forwarding.
In case of using `nginx` with reverse-proxy config, setting up of Webhook will look like:
```kotlin
requestsExecutor.setWebhook(
WEBHOOK_URL,
INTERNAL_PORT,
filter,
ENGINE_FACTORY
)
```
Here:
* `WEBHOOK_URL` - the url which will be used by Telegram system to send updates
* `INTERNAL_PORT` - the port which will be used in bot for listening of updates
* `filter` - instance of [UpdatesFilter](src/main/kotlin/com/github/insanusmokrassar/TelegramBotAPI/utils/extensions/UpdatesFilter.kt),
which will be used to filter incoming updates
* `ENGINE_FACTORY` - used factory name, for example, `CIO` in case of usage `io.ktor:ktor-server-cio` as server engine
