## Installation
```Shell
pip install html-telegraph-poster
```

## Usage
```python
>>> from html_telegraph_poster import TelegraphPoster
>>> t = TelegraphPoster(use_api=True)
>>> t.create_api_token('Elon Musk', 'Elon', 'https://www.spacex.com/') # second and third params are optional
{'access_token': '9f3bab568f*************', 'auth_url': 'https://edit.telegra.ph/auth/HFYo***********', 'author_name': 'Elon', 'short_name': 'Elon Musk', 'author_url': 'https://www.spacex.com/'}
>>> t.post(title='Just another funny joke', author='by me', text='<blockquote>Really hard way</blockquote>')
{'path': 'Just-another-funny-joke-06-05-4', 'url': 'http://telegra.ph/Just-another-funny-joke-06-05-4'}
```
##### Use graph.org instead of telegra.ph
```python
>>> t = TelegraphPoster(use_api=True, telegraph_api_url='https://api.graph.org')
```
##### We can modify this article later:
```python
>>> t.edit(text=t.text + '<p>some text at the end</p>')
{'path': 'Just-another-funny-joke-06-05-4', 'url': 'http://telegra.ph/Just-another-funny-joke-06-05-4'}
```
##### Modify page created earlier:
```python
>>> t.edit(text="<p>new text</p>", path='/Another-one-page-06-05')
{'path': 'Another-one-page-06-05', 'url': 'http://telegra.ph/Another-one-page-06-05'}
```

## Generate persistent access token
Actually it's a good idea to generate access token and put it inside environment variables.
This command will generate .env file or append  TELEGRAPH_ACCESS_TOKEN at the end of it.
Note: script will not set environment variable. You can use [python-dotenv](https://github.com/theskumar/python-dotenv),
set it manually or hardcode it when call `TelegraphPoster(access_token='access_token_string')`
```Shell
python -m html_telegraph_poster.create_account "Elon Musk" "Elon" "https://www.spacex.com/"
```

## Uploading images
```python

from html_telegraph_poster.upload_images import upload_image

# upload file
upload_image("file_path.jpg")

# upload url
upload_image("http://example.com/img.png")

# setting request and response timeout
upload_image("http://example.com/img.png", get_timeout=(5, 5), upload_timeout=(5, 5))

```
## Utils module
Utils module provides ability to make some pre-process steps before document is passed to the converter.
#### Uploading all images to the telegra.ph
```python
from html_telegraph_poster.utils import DocumentPreprocessor

dp = DocumentPreprocessor(html_string)
dp.upload_all_images()
dp.get_processed_html() # this should return html string with uploaded and replaced image urls
```
Optionally you can pass base_url if the document contains images with relative paths
```python
dp.upload_all_images(base_url='https://example.com')
dp.get_processed_html() 
```
