Simply return the result string from the Lambda
This way, Slack will just display that which is convenient.
Carl Worth [Mon, 12 Oct 2020 03:08:13 +0000 (20:08 -0700)]
Switch from event['args'] to event['text'] for input to the lambda
Since that's what we actually get from Slack, (now that we have the
"mapping template" in place so that we receive a dictionary here rather
than a bunch of x-www-form-urlencoded data).
Carl Worth [Mon, 12 Oct 2020 02:59:54 +0000 (19:59 -0700)]
Rename lamdba_function.lambda_handler to turbot_lambda.turbot_lambda
Now that I realized that the lambda_function.lambda_handler naming
isn't hard-coded in AWS but is instead just a default, (and now that
I've configured it to this instead).
Carl Worth [Sun, 11 Oct 2020 21:12:42 +0000 (14:12 -0700)]
Share the rot() implementation between both Lambda and Flask implementations
This provides a model of how to do code sharing between the two
implementations we have, (with the expectation that the code in the
"turbot" package will be generic and that code in turbot_slack and
turbot_lambda will use that common code while doing whatever
additional marshalling is necessary for their particular application
environments).
Carl Worth [Sun, 11 Oct 2020 20:59:19 +0000 (13:59 -0700)]
Move top-level flask app from turbot/turbot.py to turbot_flask/turbot.py
This is a first baby step toward teasing apart true "library" code in
turbot, (which can be shared by both the Lambda and Flask
implementations), from code that is Flask-specific.
(For symmetry, the lambda directory is renamed turbot_lambda here as well.)
Carl Worth [Sun, 11 Oct 2020 20:55:15 +0000 (13:55 -0700)]
Add target to deploy our lambda code to AWS
The existing "make deploy" target now calls out to two targets:
make flask: Deploys code to Flask app at halibut.cworth.org
make lambda: Deploys code to AWS lambda function
Carl Worth [Sun, 11 Oct 2020 17:35:45 +0000 (10:35 -0700)]
Start implementing code intended to be deployed to AWS Lambda
Here, lambda/rot.py is a copy of the turbot/rot.py code, but massaged
into the calling conventions of AWS Lambda (and without yet any actual
code to integrate with Slack in either direction).
Carl Worth [Fri, 9 Oct 2020 22:41:11 +0000 (15:41 -0700)]
Use a thread for creating the Google Sheet when a new channel is created
This allows us to return quickly so that Slack doesn't retry sending the event.
As implemented in this commit, this code is a bit cheesy in that it
disables the debug mode and error handling in slack_send_message,
(since the prior implementation of that depended on having a current
Flask app, but now that we are calling this function from a thread we
don't have a current app context).
Carl Worth [Fri, 9 Oct 2020 21:09:23 +0000 (14:09 -0700)]
Add automatic refreshing of the Google Sheets token
Otherwise, the original token expires and becomes useless after 60
minutes.
Carl Worth [Wed, 30 Sep 2020 14:04:56 +0000 (07:04 -0700)]
Remove another stale file name from a comment
The documentation example used "token.pickle" but we are now using
".gsheets-token.pickle". Here we switch to just "token file" in the
code comment so the comment is immune to any renaming.
Carl Worth [Tue, 29 Sep 2020 22:59:39 +0000 (15:59 -0700)]
Copy template sheets to newly-created spreadsheets
The TEMPLATE_SHEET_ID here is that of a spreadsheet in Trubot's
account that is named "Template".
Carl Worth [Tue, 29 Sep 2020 22:58:37 +0000 (15:58 -0700)]
Fix a stale file name embedded in a comment
We renamed this file recently so the comment was wrong. Re-word
the comment here so that we don't need to keep tracking the latest
name of this file.
Carl Worth [Tue, 29 Sep 2020 22:12:24 +0000 (15:12 -0700)]
Set the name of newly-created sheets to match the channel name
Much better than having dozens of sheets all named "untitled".
Carl Worth [Tue, 29 Sep 2020 22:08:44 +0000 (15:08 -0700)]
Initial implement of auto-creation of Google sheets
This is implemented via a Slack event listener that's listening for
the "channel_created" event. So, whenever a new channel is created,
this code will create a new Google sheet and inject a message into
the new channel with the URL of the sheet.
Carl Worth [Tue, 29 Sep 2020 22:05:21 +0000 (15:05 -0700)]
Rename .turbot.env to .slack-creds.env
I had originally chosen a generic name hoping that I could cram all
of our various credentials into this one file. But, alas, the Google
docs. credentials really want to be in a JSON file so they will be
separate.
Given that, I'll give each file a specific name, starting with this
Slack-specific file.

Makefile: Fix DO_NOT_DEPLOY implementation to work with multiple files
The --exclude option to rsync expects a single file, so we need to
arrange to pass it multiple times if we have multiple files in the
value of the DO_NOT_DEPLOY variable. Fortunately, this is a perfect
job for patsubst.
Carl Worth [Tue, 29 Sep 2020 18:15:54 +0000 (11:15 -0700)]
Add a listener for the Slack "channel_created" event
Currently this just posts a simple message when a channel is
created. Eventually, we'll want to do something different such as
creating a puzzle sheet and linking/pinning it to the channel.
Carl Worth [Tue, 29 Sep 2020 19:44:58 +0000 (12:44 -0700)]
Break out rot.py and slack.py from turbot.py
Using separate modules to make the code more maintainable.
Carl Worth [Tue, 29 Sep 2020 17:07:15 +0000 (10:07 -0700)]
Make a top-level turbot package
This will be useful as we soon start splitting up the single turbot.py
file into multiple modules that want to include things from each
other.
Carl Worth [Tue, 29 Sep 2020 17:06:04 +0000 (10:06 -0700)]
Ignore the __pycache__ directory
Something keeps auto-creating this, so I know it's not source we would
ever want to commit to git.

Abstract out two slack-related functions
The two new functions are slack_is_valid_request and slack_send_reply.
These functions provide some shared code for dealing with slack to
avoid code duplication.
These functions also provide a debug mode (that doesn't use slack at
all). This is a convenience for testing the implementation of slash
commands in a local "make run" session without needing to touch Slack
endpoints at all. (Instead, all requests are considered valid and
slack replies are simply printed to stdout.)
Carl Worth [Tue, 29 Sep 2020 15:35:46 +0000 (08:35 -0700)]
Convert "make run" to use "flask run" instead of direct python script execution
This will simplify some future work (regarding reorganizing the code into
a package, etc.) so that we don't have to try to simultaneously support
running as both a script and as a module.
Carl Worth [Tue, 29 Sep 2020 13:20:59 +0000 (06:20 -0700)]
Use a raw string for a regular expression
Previously, the string had an unrecognized escape sequence ('\*').
With a non-raw string we could have doubled the backslash, but it's
much cleaner to just use a raw string instead, (so that backslashes
are used for regular-expression escaping, and not also for string
escaping).
Carl Worth [Tue, 29 Sep 2020 13:15:32 +0000 (06:15 -0700)]
Add missing include of flask.make_response
Revealing that I hadn't actually tested this error case (*blush*).

Fix some code style issues identified by flake8
Some of the things fixed include TAB based indentation of a
documentation string, some unneeded semicolons, a missing exception
name, and an excessively long line.

Add signature verification fo the /rot slash command
This prevents someone abusing our bot by spoofing messages appearing
to have come from Slack. This way we won't reply to any command
request unless it actually comes from Slack.
Carl Worth [Sun, 27 Sep 2020 21:26:47 +0000 (14:26 -0700)]
Add some documentation for the functions we have defined here
Since we want to have maintainable code.

Add requirements for using Google Sheets API
And update all other requirements while we're at it.
Carl Worth [Sat, 26 Sep 2020 05:22:32 +0000 (22:22 -0700)]
Add a route to implement a /rot slash command
This is to be used as follows:
/rot [count] String to rotate
The optional count indicates a number of positions to rotate every
letter in the string. If it is not provided, all rotations will be
printed.
Note: The count can also be provided as an '*' character to explicitly
request all possible rotations.

Restore handling of error events from Slack
This is better than what I had copied from the example a few commits
ago because this properly logs through the python logging system, (so
the error message will appear in the Apache log file).

Fix turbot.wsgi to be able to find its environment variables
We can't rely on the current working directory of the Apache process,
so we need to use an explicit path here in order to find our file
with environment variables in it.

Put my own creation of the Flask app back
Rather than relying on the one in the Slack events API.
This means the WSGI configuration should work once again.

Trim down the program to not have any custom routes
I'm just verifying here that I don't need to have these in order to
get the Slack challenge verification to work.

Add Slack dependencies and minimum boilerplate to our flask app
This entirely replaces our flask setup, (which also breaks our current
WSGI setup too) but is based on the exact demo code from:
https://github.com/slackapi/python-slack-events-api/blob/main/example/example.py
I want to start with this to ensure I can at least get a correct
challenge working. After I get this working this way, I'll plan to put
direct flask code back in place and integrated with the web server via
WSGI.

Initial commit of turbot
Turbot will eventually be a Slack bot for the Halibut That Bass team.
As of this commit, turbot.py is just a simple flask app implementing a
REST API (to query, add, delete TODO items). Additionally, this commit
includes the Makefile pieces to manage python dependencies and to
deploy the program to our server.
There's not yet any actual Slack-application code here yet.
