              "License" shall mean the terms and conditions for use, reproduction,
              and distribution as defined by Sections 1 through 9 of this document.
        
              "Licensor" shall mean the copyright owner or entity authorized by
              the copyright owner that is granting the License.

              other entities that control, are controlled by, or are under common
              control with that entity. For the purposes of this definition,
              "control" means (i) the power, direct or indirect, to cause the
              direction or management of such entity, whether by contract or
              otherwise, or (ii) ownership of fifty percent (50%) or more of the
              outstanding shares, or (iii) beneficial ownership of such entity.

              including but not limited to software source code, documentation
              source, and configuration files.

              not limited to compiled object code, generated documentation,
              and conversions to other media types.
        
              "Work" shall mean the work of authorship, whether in Source or
              Object form, made available under the License, as indicated by a
              copyright notice that is included in or attached to the work
              (an example is provided in the Appendix below).
        
              "Derivative Works" shall mean any work, whether in Source or Object
              form, that is based on (or derived from) the Work and for which the
              editorial revisions, annotations, elaborations, or other modifications
              represent, as a whole, an original work of authorship. For the purposes
              of this License, Derivative Works shall not include works that remain
              separable from, or merely link (or bind by name) to the interfaces of,
              the Work and Derivative Works thereof.
        
              "Contribution" shall mean any work of authorship, including
              the original version of the Work and any modifications or additions
              to that Work or Derivative Works thereof, that is intentionally
              submitted to Licensor for inclusion in the Work by the copyright owner
              or by an individual or Legal Entity authorized to submit on behalf of
              the copyright owner. For the purposes of this definition, "submitted"
              means any form of electronic, verbal, or written communication sent
              to the Licensor or its representatives, including but not limited to
              communication on electronic mailing lists, source code control systems,
              and issue tracking systems that are managed by, or on behalf of, the
              Licensor for the purpose of discussing and improving the Work, but
              excluding communication that is conspicuously marked or otherwise

              "Contributor" shall mean Licensor and any individual or Legal Entity
              on behalf of whom a Contribution has been received by Licensor and
              subsequently incorporated within the Work.
        
           2. Grant of Copyright License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              copyright license to reproduce, prepare Derivative Works of,
              publicly display, publicly perform, sublicense, and distribute the
              Work and such Derivative Works in Source or Object form.
        
           3. Grant of Patent License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              (except as stated in this section) patent license to make, have made,
              use, offer to sell, sell, import, and otherwise transfer the Work,
              where such license applies only to those patent claims licensable
              by such Contributor that are necessarily infringed by their
              Contribution(s) alone or by combination of their Contribution(s)
              with the Work to which such Contribution(s) was submitted. If You
              institute patent litigation against any entity (including a
              cross-claim or counterclaim in a lawsuit) alleging that the Work
              or a Contribution incorporated within the Work constitutes direct
              or contributory patent infringement, then any patent licenses
              granted to You under this License for that Work shall terminate
              as of the date such litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or
                  Derivative Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works
                  that You distribute, all copyright, patent, trademark, and
                  attribution notices from the Source form of the Work,
                  excluding those notices that do not pertain to any part of
                  the Derivative Works; and
        
              (d) If the Work includes a "NOTICE" text file as part of its
                  distribution, then any Derivative Works that You distribute must
                  include a readable copy of the attribution notices contained
                  within such NOTICE file, excluding those notices that do not
                  pertain to any part of the Derivative Works, in at least one
                  of the following places: within a NOTICE text file distributed
                  as part of the Derivative Works; within the Source form or
                  documentation, if provided along with the Derivative Works; or,
                  within a display generated by the Derivative Works, if and
                  wherever such third-party notices normally appear. The contents
                  of the NOTICE file are for informational purposes only and
                  do not modify the License. You may add Your own attribution
                  notices within Derivative Works that You distribute, alongside
                  or as an addendum to the NOTICE text from the Work, provided
                  that such additional attribution notices cannot be construed
                  as modifying the License.
        
              You may add Your own copyright statement to Your modifications and
              may provide additional or different license terms and conditions
              for use, reproduction, or distribution of Your modifications, or
              for any such Derivative Works as a whole, provided Your use,
              reproduction, and distribution of the Work otherwise complies with
              the conditions stated in this License.
        
           5. Submission of Contributions. Unless You explicitly state otherwise,
              any Contribution intentionally submitted for inclusion in the Work
              by You to the Licensor shall be under the terms and conditions of
              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,
              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf
              of any other Contributor, and only if You agree to indemnify,
              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.
        
           END OF TERMS AND CONDITIONS
        
           APPENDIX: How to apply the Apache License to your work.
        
              To apply the Apache License to your work, attach the following
              boilerplate notice, with the fields enclosed by brackets "[]"
              replaced with your own identifying information. (Don't include
              the brackets!)  The text should be enclosed in the appropriate
              comment syntax for the file format. We also recommend that a
              file or class name and description of purpose be included on the
              same "printed page" as the copyright notice for easier
              identification within third-party archives.

# RedShot

`RedShot` is an event-based Python package that provides a Selenium wrapper for automating WhatsApp Web workflows. It allows you to interact with WhatsApp Web to send and receive messages, search chats, and more.

Whatsapp Web is constantly changing so this library is very susceptible to breaking and bugs. I'll do my best to fix these as soon as possible. Also, expect much more functionality in future updates.

**Note:** Use this library at your own risk. Whatsapp does not allow the unauthorised use of automated or bulk messaging.

## Installation

```bash
pip install redshot
```

## Quick Start

See the examples folder for more.

```python
from redshot import Client

client = Client()

@client.event("on_start")
def on_start():
    print("Client has started")
    client.stop()

client.run()
```

## Authentication

Whatsapp Web allows users to connect their whatsapp web to their phone via by scanning a QR code in the app. To allow for this session data to persist between script executions, we can implement different authentication strategies.

Currently, there is two working authentication strategies: `LocalProfileSession` that uses the chrome user data directory and `NoAuth` which saves no information between sessions:

`redshot.auth.LocalProfileSession(data_dir, profile="selenium")`

Parameters:
- data_dir: The chrome user data directory to be used
- profile: The chrome profile to be used

`redshot.auth.NoAuth()`

## Client Initialisation

`redshot.Client(auth=None, poll_freq=0.25, unread_messages_sleep=0.5, headless=True)`

Parameters:
- auth: An authentication strategy (if None this defaults to `NoAuth`)
- poll_freq: Time between polls of the whatsapp webpage
- unread_messages_sleep: Time waited for the unread messages section to load
- headless: If true, the chrome UI interface won't be displayed

## Events

Events listeners are instantiated using the `redshot.Client.event` decorator as follows:

```python
@client.event("on_event")
def on_event(*event_args):
    print("Event triggered!")
```

Event types:
- `on_start`: Called once the chrome driver object has been created and has opened https://web.whatsapp.com/
- `on_auth`: Called when the authentication screen appears
- `on_qr`: Called when the qr code has loaded in the authentication screen
  - Arguments:
<br />`qr` - the QR code image's binary string
- `on_qr_change`: Called when a new qr code is generated in the authentication screen (if the old qr code wasn't scanned in time)
  - Arguments:
<br />`new_qr` - The new QR code image's binary string
- `on_loading`: Called when a loading screen appears:
  - Arguments:
<br />`loading_chats`: True if the loading screen appears as a result of the qr code being scanned
- `on_logged_in`: Called when the client successfully logs in
- `on_unread_chat`: Called on each poll of the mainloop with an unread chat
  - Arguments:
<br />`chat`: A `SearchResult` object containing information about the unread chat
- `on_tick`: Called at the end of each tick of the mainloop

## Client Functions

`redshot.Client.run()`: Begins the client main loop (in an `asyncio` thread).

`redshot.Client.stop()`: Stops the client's main loop once the current tick of the main loop is complete.
<br />Note that the `stop` method should be run within the main loop's thread i.e. in an event listener.
<br />Also, calling `stop` too soon after `send_message` may cause the message not to be sent (depending on internet speeds).

`redshot.Client.get_recent_messages(search_field, sleep=1)`: Get's the recent messages from the first chat in the search results.

Parameters:
- `search_field`: Used in the whatsapp searchbar to find the given chat

`redshot.Client.send_message(search_field, message)`: Sends a message to the first chat in the search results.

Parameters:
- `search_field`: Used in the whatsapp searchbar to find the given chat
- `message`: The message to be sent to the given chat

`redshot.Client.search(search_field)`: Returns a list of `SearchResult` containing: chats, groups in common, contacts, messages.

Parameters:
- `search_field`: Used in the whatsapp searchbar to obtain the search results

## Objects

Class `redshot.object.Message`:

- `info`: A `MessageInfo` object
- `text`: A string containing the message's text
- `quote`: A `MessageQuote` object
- `link`: A `MessageLink` object
- `has_quote()`: True if the `Message` contains a quote
- `has_link()`: True if the `Message` contains a link
- `as_string()`: A formatted string of the message contents

Class `redshot.object.MessageInfo`:

- `time`: The time the message was sent
- `date`: The date the message was sent
- `user`: The user who sent the message
- `as_string()`: A formatted string of the message info contents

Class `redshot.object.MessageQuote`:

- `user`: The user who sent the quoted message
- `text`: The text in the quoted message
- `as_string()`: A formatted string of the message quote contents

Class `redshot.object.MessageLink`:

- `title`: The title of the linked url
- `description`: The description of the linked url
- `url`: The linked url
- `as_string()`: A formatted string of the message link contents

Class `redshot.object.SearchResult`:

- `result_type`: The search result type
- `title`: The search result's time
- `datetime`: The search result's datetime (either a date or a time)
- `info`: The search result's info section
- `unread_messages`: The number of unread messages
- `group`: The group the search result is in (if the search result is a chat)

## To Do List

- [ ] Add a `MessageImage` class and parse images in messages
- [ ] Parse emojis within messages and other contexts
- [ ] Add support for users to override locators in case of bugs
- [ ] Replace `time.sleep` for waiting for messages or search results to load
- [ ] Implement better error handling
- [ ] Add support for more features - chat descriptions/info, polls, images, files etc
- [ ] Find a way to save data between sessions without using a user data directory. See [here](https://stackoverflow.com/questions/79154388/how-to-inject-whatsapp-web-session-to-stay-logged-in-with-selenium) (suggestions are more than welcome). Also look at `redshot.auth.LocalSessionAuth` for updates.
