<h1>Posting Blog Posts as Twitter Threads Part 1/n</h1>
<p>Why? Eh, no good reason, but should be fun.</p>
<h2>Plan of Action</h2>
<p>I recently shifted my website to a static site generator I wrote specifically for myself.
Thus, it should be easy to just add a feature into it to check for new posts, split the text into chunks for Twitter threads and post them on Twitter.
I am not handling lists or images right now.</p>
<h2>Time to Code</h2>
<p>First, the dependency: tweepy for tweeting.</p>
<p><code>pip install tweepy</code></p>
<div class="codehilite"><pre><span></span><code><span class="kn">import</span> <span class="nn">os</span>

<p>The program need to convert the blog post into text fragments.</p>
<p>It reads the markdown file, removes the top YAML content, checks for headers and splits the content.</p>

<p>Every status update using tweepy has an id attached to it, for the next tweet in the thread, it add that ID while calling the function.</p>
<p>For every tweet fragment, it also append 1/n.</p>

<p>Finally, it replies to the last tweet in the thread with the link of the post.</p>

<h2>What's Next?</h2>
<p>For the next part, I will try to append the code as well.
I actually added the code to this post after running the program.</p>
