# go-tdlib
|
||||
|
||||
Go wrapper for [TDLib (Telegram Database Library)](https://github.com/tdlib/td) with full support of TDLib v1.2.0
|
||||
|
||||
## TDLib installation
|
||||
|
||||
### Ubuntu 18.04 / Debian 9
|
||||
|
||||
apt-get update -y
|
||||
apt-get install -y \
|
||||
build-essential \
|
||||
ca-certificates \
|
||||
ccache \
|
||||
cmake \
|
||||
git \
|
||||
gperf \
|
||||
libssl-dev \
|
||||
libreadline-dev \
|
||||
zlib1g-dev
|
||||
git clone --depth 1 -b "v1.2.0" "https://github.com/tdlib/td.git" ./tdlib-src
|
||||
mkdir ./tdlib-src/build
|
||||
cd ./tdlib-src/build
|
||||
cmake -j$(getconf _NPROCESSORS_ONLN) -DCMAKE_BUILD_TYPE=Release ..
|
||||
cmake -j$(getconf _NPROCESSORS_ONLN) --build .
|
||||
make -j$(getconf _NPROCESSORS_ONLN) install
|
||||
rm -rf ./../../tdlib-src
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
### Client
|
||||
|
||||
[Register an application](https://my.telegram.org/apps) to obtain an api_id and api_hash
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/zelenin/go-tdlib/client"
|
||||
)
|
||||
|
||||
func main() {
|
||||
client.SetLogVerbosityLevel(1)
|
||||
client.SetLogFilePath("/dev/stderr")
|
||||
|
||||
// client authorizer
|
||||
authorizer := client.ClientAuthorizer()
|
||||
go client.CliInteractor(authorizer)
|
||||
|
||||
// or bot authorizer
|
||||
botToken := "000000000:gsVCGG5YbikxYHC7bP5vRvmBqJ7Xz6vG6td"
|
||||
authorizer := client.BotAuthorizer(botToken)
|
||||
|
||||
const (
|
||||
apiId = 00000
|
||||
apiHash = "8pu9yg32qkuukj83ozaqo5zzjwhkxhnk"
|
||||
)
|
||||
|
||||
authorizer.TdlibParameters <- &client.TdlibParameters{
|
||||
UseTestDc: false,
|
||||
DatabaseDirectory: "./.tdlib/database",
|
||||
FilesDirectory: "./.tdlib/files",
|
||||
UseFileDatabase: true,
|
||||
UseChatInfoDatabase: true,
|
||||
UseMessageDatabase: true,
|
||||
UseSecretChats: false,
|
||||
ApiId: apiId,
|
||||
ApiHash: apiHash,
|
||||
SystemLanguageCode: "en",
|
||||
DeviceModel: "Server",
|
||||
SystemVersion: "1.0.0",
|
||||
ApplicationVersion: "1.0.0",
|
||||
EnableStorageOptimizer: true,
|
||||
IgnoreFileNames: false,
|
||||
}
|
||||
|
||||
tdlibClient, err := client.NewClient(authorizer)
|
||||
if err != nil {
|
||||
log.Fatalf("NewClient error: %s", err)
|
||||
}
|
||||
|
||||
me, err := tdlibClient.GetMe()
|
||||
if err != nil {
|
||||
log.Fatalf("GetMe error: %s", err)
|
||||
}
|
||||
|
||||
log.Printf("Me: %s %s [%s]", me.FirstName, me.LastName, me.Username)
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
### Receive updates
|
||||
|
||||
```go
|
||||
responses := make(chan client.Type, 100)
|
||||
tdlibClient, err := client.NewClient(authorizer, client.WithListener(responses))
|
||||
if err != nil {
|
||||
log.Fatalf("NewClient error: %s", err)
|
||||
}
|
||||
|
||||
for response := range responses {
|
||||
if response.GetClass() == client.ClassUpdate {
|
||||
log.Printf("%#v", response)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
* WIP. Library API can be changed in the future
|
||||
* The package includes a .tl-parser and generated [json-schema](https://github.com/zelenin/go-tdlib/tree/master/data) for creating libraries in other languages
