-# Source Code
-
-I don't want to bury the lede here, so if you'd like to see the full source code
-I use to email myself plaintext poems daily, visit the repository:
-[daily-poem.git](https://git.sr.ht/~cyborg/daily-poem).
-
-# My Daily Dose of Poetry
-
-Most of my programming projects are small, random projects that are made
-strictly to fix some small problem I have or enhance my quality of life.
-
-In this case, I was looking for a simply and easy way to get a daily dose of
-literature or poetry to read in the mornings.
-
-However, I don't want to sign up for a random mailing list on just any website.
-I also don't want to have to work to find the reading content each morning, as I
-know I would simply give up and stop reading daily.
-
-Thus, I found a way to deliver poetry to myself in plain-text format, on a daily
-basis, and scheduled to deliver automatically.
-
-# Prerequisites
-
-This solution uses Python and email, so the following process requires the
-following to be installed:
-
-1. An SMTP server, which can be as easy as installing `mailutils` if you're on a
- Debian-based distro.
-2. Python (& pip!)
-3. The following Python packages: `email`, `smtplib`, `json`, and `requests`
-
-# Breaking Down the Logic
-
-I want to break down the logic for this program, as it's quite simple and
-informational.
-
-## Required Packages
-
-This program starts with a simple import of the required packages, so I wanted
-to explain why each package is used:
-
-```python
-from email.mime.text import MIMEText # Required for translating MIMEText
-import smtplib # Required to process the SMTP mail delivery
-import json # Required to parse the poetry API results
-import requests # Required to send out a request to the API
-```
-
-## Sending the API Request
-
-Next, we need to actually send the API request. In my case, I'm calling a random
-poem from the entire API. If you want, you can call specific poems or authors
-from this API.
-
-```python
-json_data = requests.get('https://poetrydb.org/random').json()
-```
-
-This gives us the following result in JSON:
-
-```json
-[
- {
- "title": "Sonnet XXII: With Fools and Children",
- "author": "Michael Drayton",
- "lines": [
- "To Folly",
- "",
- "With fools and children, good discretion bears;",
- "Then, honest people, bear with Love and me,",
- "Nor older yet, nor wiser made by years,",
- "Amongst the rest of fools and children be;",
- "Love, still a baby, plays with gauds and toys,",
- "And, like a wanton, sports with every feather,",
- "And idiots still are running after boys,",
- "Then fools and children fitt'st to go together.",
- "He still as young as when he first was born,",
- "No wiser I than when as young as he;",
- "You that behold us, laugh us not to scorn;",
- "Give Nature thanks you are not such as we.",
- "Yet fools and children sometimes tell in play",
- "Some, wise in show, more fools indeed than they."
- ],
- "linecount": "15"
- }
-]
-```
-
-## Parsing the API Results
-
-In order to parse this into a readable format, we need to use the `json` package
-and extract the fields we want. In the example below, I am grabbing every field
-presented by the API.
-
-For the actual poem content, we need to loop over each line in the `lines`
-variable since each line is a separate string by default.
-
-> You _could_ also extract the title or author and make another call out to the
-> API to avoid having to build the plaintext poem with a loop, but it just
-> doesn't make sense to me to send multiple requests when we can create a simple
-> loop on our local machine to work with the data we already have.
->
-> For
-> [example](https://poetrydb.org/title/Sonnet%20XXII:%20With%20Fools%20and%20Children/lines.text),
-> look at the raw data response of this link to see the poem's lines returned in
-> plaintext.
-
-```python
-title = json_data[0]['title']
-author = json_data[0]['author']
-line_count = json_data[0]['linecount']
-lines = ''
-for line in json_data[0]['lines']:
- lines = lines + line + "\n"
-```
-
-## Composing the Email
-
-Now that I have all the data I need, I just need to compose it into a message
-and prepare the message metadata.
-
-For my daily email, I want to see the title of the poem first, followed by the
-author, then a blank line, and finally the full poem. This code snippet combines
-that data and packages it into a MIMEText container, ready to be emailed.
-
-```python
-msg_body = title + "\n" + author + "\n\n" + lines
-msg = MIMEText(msg_body)
-```
-
-Before we send the email, we need to prepare the metadata (subject, from, to,
-etc.):
-
-```python
-sender_email = 'example@server.local'
-recipient_emails = ['user@example.com']
-msg['Subject'] = 'Your Daily Poem (' + line_count + ' lines)'
-msg['From'] = sender_email
-msg['To'] = recipient_email
-```
-
-## Sending the Email
-
-Now that I have everything ready to be emailed, the last step is to simply
-connect to an SMTP server and send the email out to the recipients. In my case,
-I installed `mailutils` on Ubuntu and let my SMTP server be `localhost`.
-
-```python
-smtp_server = 'localhost'
-s = smtplib.SMTP(smtp_server)
-s.sendmail(sender_email, recipient_emails, msg.as_string())
-s.quit()
-```
-
-# The Result!
-
-Instead of including a screenshot, I've copied the contents of the email that
-was delivered to my inbox below since I set this process up in plaintext format.
-
-```txt
-Date: Wed, 22 Jun 2022 14:37:19 +0000 (UTC)
-From: REDACTED
-To: REDACTED
-Subject: Your Daily Poem (36 lines)
-MIME-Version: 1.0
-Content-Transfer-Encoding: 8bit
-Content-Type: text/plain; charset=utf-8
-
-Sonnet XXII: With Fools and Children
-Michael Drayton
-
-With fools and children, good discretion bears;
-Then, honest people, bear with Love and me,
-Nor older yet, nor wiser made by years,
-Amongst the rest of fools and children be;
-Love, still a baby, plays with gauds and toys,
-And, like a wanton, sports with every feather,
-And idiots still are running after boys,
-Then fools and children fitt'st to go together.
-He still as young as when he first was born,
-No wiser I than when as young as he;
-You that behold us, laugh us not to scorn;
-Give Nature thanks you are not such as we.
-Yet fools and children sometimes tell in play
-Some, wise in show, more fools indeed than they.
-```
-
-# Scheduling the Daily Email
-
-Last, but not least, is scheduling this Python script with `crontab`. To
-schedule a script to run daily, you can add it to the `crontab` file. To do
-this, open `crontab` in editing mode:
-
-```sh
-crontab -e
-```
-
-In the file, simply paste the following snippet at the bottom of the file and
-ensure that the file path is correctly pointing to wherever you saved your
-Python script:
-
-```config
-0 8 ** ** ** python3 /home/<your_user>/dailypoem/main.py
-```
-
-We have now set up the script and scheduled it to run daily at 08:00!
