# slashbot
Slashbot makes it easy to create Slack slash commands using AWS Lambda functions. These can be handy for creating a secure way to execute automated tasks, even from a mobile device. Perfect for developing "chatops" type applications.

Features:
* Uses Slack Apps API (rather than the legacy slash command API)
* Authenticates requests following Slack recommended best practice (https://api.slack.com/authentication/verifying-requests-from-slack)
* Supports multiple slash commands with a single bot
* Enables limiting certain commands to specific users via a simple ACL model.

## Installation

pip install slashbot [--target=source_directory]
(the --target option is used to include your packages in your source folder so they willl be included in your AWS Lambda artifact)

## Usage

```python
import os
import time
import slashbot

# https://api.slack.com/authentication/verifying-requests-from-slack
slashbot.SLACK_SIGNING_SECRET = os.environ.get("SLACK_SIGNING_SECRET")

# Define a default response
@slashbot.route("*")
def default(cmd: slashbot.SlashCommand):
if not cmd.provided_verb: #Nothing beyond the slash command
return help(cmd)
return (
f"This is a default response. `{cmd.provided_verb}` is not a recognized command. \n"
+ help(cmd)
)

@slashbot.route("help")
#Handlers take a SlashCommand as input and return text
def help(cmd: slashbot.SlashCommand):
return f"Here is some helpful text"

@slashbot.route("hello")
def functionnamesdontmatter(cmd: slashbot.SlashCommand):
return f"Hello {cmd.user_name}"

# Support for multi word verbs
@slashbot.route("good bye")
def good_bye(cmd: slashbot.SlashCommand):
return f"Good bye {cmd.user_name}"

# An ack is automatically sent to Slack within the required 3 seconds.
# So your function can take up to the duration of a lambda function (15 mins)
@slashbot.route("echo")
def echowithdelay(cmd):
time.sleep(300)
return f"Echo {' '.join(cmd.command_args)}"

# acl can be optionally provided (acl can be single user name or array of user names)
@slashbot.route("secure stuff", acl="anybodybutme")
def secure_stuff(_):
...
# do some scary stuff limited to specific users
return ""

def handler(event, context):
return slashbot.main(event, context)

```

## Todo

* Add CD (push to PyPI)
* Validation on routes to detect conflicting/duplicate entries
* Slack APP Manifest
* Terraform Example
