 # Blog setup with markdown, rust & git
 
-I've recently went trough a lot of changes in my career such as starting freelancing, setting up my own projects and wanting to take a serious attempt at solo game-dev. With this I figured it'd be nice to have a dev blog of sorts to keep track of progress and maybe share some interesting research or developments.
+Hey everyone. This is the first post I write for the blog I'm starting, which is Coincidentally about how I've structured the software surrounding my blog.
+
+First off, I've been wanting to do a lot recently:
+
+- Moving away from Windows to using Linux and MacOS for development and gaming
+- Switching from VSCode/Cursor to neovim
+- Switching from working for an employer to becoming a solo dev/freelancer
+- Dedicate time to solo game development
+
+Because of this, I figured it would be a good time to set up a blog, both for documenting whatever I'm working on and to get the word out about my work. 
 
 ## The blog design
 
 I wanted to have a setup that generates static html from something like markdown. Then recently I stumbled across this [https://gaultier.github.io/blog/making_my_static_blog_generator_11_times_faster.html](https://gaultier.github.io/blog/making_my_static_blog_generator_11_times_faster.html) 
 
+I decided to do something similar, however I used rust as it has some popular existing libraries for web servers and parsing markdown. The reason for writing an application to host the blog is that I wanted to have it automatically respond to a git webhook which would automatically pull the latest git repo and then rebuild the articles from their markdown files.
+
+## HTML
+
+Of course there is also some styling and markup required for the shell, like the navigation bar and footers.\
+I decided to go with a simple list of html templates that get included by the application and scan it for tags to inject certain magic values, like the list of posts or timestamps.
+
+For example, here is what the page you're looking at looks like:
+
+```html
+$<include src="header.html"/>
+    <article>
+        $<post-html/>
+    </article>
+    <p><a href="/">← Back to home</a></p>
+$<include src="footer.html"/>
+```
+
+Which can be parsed very quickly by a simple scanner that triggers on $< and then reads the key and map of `<String,String>` parameters.
+
+This allows me to just write template code like this:
+```html
+<title>$<title default="Guus' blog" pre="Guus - "></title>
+```
+
+and process it in rust like this:
+```rs
+"title" => {
+    if let Some(post_name) = current_post {
+        let post = post_manager
+            .get_post(post_name)
+            .await
+            .ok_or_else(|| format!("Post '{}' not found", post_name))?;
+
+        let none: String = "".to_string();
+        let pre = attrs.get("pre").unwrap_or(&none);
+        let postfix = attrs.get("post").unwrap_or(&none);
+
+        Ok(format!("{}{}{}", pre, post.title, postfix))
+    } else {
+        let def = attrs
+            .get("default")
+            .and_then(|s| Some(s.clone()))
+            .unwrap_or("<title not set>".to_string());
+        Ok(def.to_string())
+    }
+}
+```
+
+All the HTML code that has been generated like this is then cached until the next the blog update is triggered by my pushing a new post to git.
+
+## Styling
+
+For the styling, I added some minimal CSS to center the contents, limit the width and change the font sizes.\
+I wanted to keep it simple so the layout works on both a desktop browser, and on mobile phone screens. This also allows you to dock the window to a side of your screen or second vertical monitor in case you wanted to reference it for some code which I find useful.
+
+## Conclusion
+
+I like this design as it's easy to deploy locally for previewing, and adding new posts or making edits is as simple as `git commit && git push`. I can keep posts I'm working on in separate branches and progressively work on them like that.
+
+If you're interested in the source code, or would like to use it for yourself feel free to check it out [here](https://git.bakje.coffee/guus/blog).
