Like most people, I like listening to music.
Also like most people, I don't like listening to ads or paying subscriptions^\[0\]^. Spotify's free tier is pretty good, and I can block their ads by using the web player and uBlock Origin.
I'm mostly content with that, but there are still some annoyances - I can't listen offline, the UI is a little frustrating, and even though the ads are blocked, the player still sometimes freezes when an ad is supposed to be playing (so the next song isn't played, have to reload the page). Combined with not morally being a fan of relying on a for-profit third-party service for my music, I decided today to write a few scripts to download all the songs on my favourite Spotify playlist (around 60 songs).
First step is getting all the song and artist names on my playlist from Spotify. I did find an [Spotify API endpoint](https://developer.spotify.com/documentation/web-api/reference/get-playlists-tracks), but it seemed like a pain with OAuth required. Instead, I just opened the playlist in my browser. After scrolling down to load all the playlist tracks, I ran something similar to the following to get all the track names:
```javascript
[...document.querySelectorAll(".iCQtmPqY0QvkumAOuCjr")].map((d) => d.innerText)
```
After a bit of processing with Javascript, vim find-and-replace commands, and a few manual corrections, I ended up with a `songs.txt` file in this format:
```
1|Alice in Freezer|Orangestar
2|無人駅|n-buna
...and so on
```
Now that we have all the song and artist names, we need to fetch the Youtube urls of the songs, so we can download them with [yt-dlp](https://github.com/yt-dlp/yt-dlp).
It turns out the Youtube search API also needs an API key, so I used the [usetube](https://github.com/valerebron/usetube) npm package, which scrapes the actual web page instead of using the API. Here's the code:
```javascript
const fs = require("fs");
const yt = require("usetube");
async function main() {
let songs = fs.readFileSync("../songs.txt", "utf-8").split("\n");
for (let i = 0; i < songs.length; i++) {
let song_name = songs[i].split("|")[1];
let artist_name = songs[i].split("|")[2];
console.log(song_name+" "+artist_name);
const videos = (await yt.searchVideo(song_name+" "+artist_name)).videos;
songs[i] = songs[i]+"|https://youtube.com/watch?v="+videos[0].id;
console.log(songs[i].split("|")[3]);
}
fs.writeFileSync("../songs.txt", songs.join("\n"), "utf-8");
}
main();
```
Now `songs.txt` looks a little like this:
```
1|Alice in Freezer|Orangestar|https://youtube.com/watch?v=jQmYZWjLwzw
2|無人駅|n-buna|https://youtube.com/watch?v=G8PFPUCNOg4
...and so on
```
The final step is just writing a bash script to download all the songs. I don't really know much bash, but after a few StackOverflow searches, I got a working script:
```bash
#!/bin/bash
while IFS= read -r line; do
IFS='|' read -ra ADDR <<< "$line"
for i in "${!ADDR[@]}"; do
printf "\n${ADDR[$i]}"
if [ $i -eq 3 ]; then
yt_dlp -x --audio-format mp3 "${ADDR[$i]}"
fi
done
done < songs.txt
```
Yay!
This was a pretty "boring" project that didn't involve much thinking or code. But being able to automate small, tedious stuff like this is a pretty underrated perk of having even a little programming knowledge.
===
- \[0\]: It's almost like artists are people too, and need to make money to support themselves! In all seriousness though, Spotify pays artists something like $0.003 USD per stream. It makes much more sense to support them through buying albums or going to concerts, instead of wasting time listening to ads.

There used to be a different blog here. But it wasn't very good, [code](https://github.com/jetstream0/Markup-to-HTML) *and* writing-wise. So I decided to rewrite everything. There used to be a different blog here. But it wasn't very good, [code](https://github.com/jetstream0/Markup-to-HTML) *and* writing-wise. So I decided to rewrite everything.
The old blog was an express server that looked for `.md` files in a directory, converted them to HTML, and served it. That worked mostly fine. However, the converter didn't support many Markdown features, and was pretty buggy. Using an express server also meant that the site wasn't static, and had limited options for hosting.

Replit's free tier was pretty unreliable, and Render only allowed one free web service per account, which I was already using to run my [faucet](https://faucet.prussia.dev). I could've created a new Render account, but they recently started requiring credit card verification, which I didn't really want to do.

Besides, making the blog static instead of relying on an express server wouldn't be that hard. A month before, I had already wrote a better (?) or at least more fully featured Markdown to HTML parser, [Makoto](https://github.com/jetstream0/Makoto-Markdown-to-HTML), so that was already one of the problems with the old blog solved.

### Makoto ### Makoto
Makoto is the Markdown-to-HTML parser, made with no dependencies. It was made around two months before Ryuji and Saki, and is meant to be more of a standalone thing. This is the sole npm dependency of the project. I `npm install`ed it instead of just copying the file over mostly because I published Makoto to npm and wanted to make sure it worked. Also, it has a different license, documentation and stuff. Makoto is the Markdown-to-HTML parser, made with no dependencies.

All the standard Markdown are supported (headers, bolds, italics, images, links, blockquotes, unordered lists, ordered lists, code, code blocks...), as well as superscripts and tables (although tables are probably buggy). Makoto also does some pretty neat stuff like passing on the language of the code block (if given) as a class in the resulting div: `code-<language>`, or automatically add ids to headers, so they can have anchor links.

Ryuji is a simple templating system that supports `if` statements, `for` loops, components, and inserting variables.

There was no way to see the current index in a for loop, or the max index (length-1) of whatever variable we were looping over. This was needed for the tag links in the post.

In addition, if statements only checked if the variable was truthy (not `false` or `0` or `""`), but I needed if statements making sure two variables were equal, as well as if statements making sure two variables were *not* equal. You can see this being used in the post's tags along with the new for loop features, as well as the "Next Post" link at the bottom of the post.

Formatting the code a little nicer, this is what it looks like: Formatting the code a little nicer, this is what it looks like:

Ok, in the first line (`for:post.tags:tag:index:max`), we are looping over the variable `post.tags`, and assigning each item in `post.tags` as the variable `tag`. That's nothing new, what's new is the `:index:max` portion. `index` is the index variable, starting at 0 and incrementing every loop, while `max` is the maximum index (the length of the variable to loop over - 1).

If you look at the Ryuji code, now you can see that it is looping over the tags of the post, and creating a link for each tag. If the tag is *not* the last tag (`index` is not equal to `max`), we will also add a comma (and a space).

if index != max: if index != max:
html += "," html += ","
index += 1 index += 1

## Putting It All Together ## Putting It All Together
When building, the program (`index.ts`) reads `/posts/_metadata.json` and passes all the post metadata information to the `templates/index.html` template, which is the home page! Then, it renders all the posts with the `templates/post.html` template and outputs to `/posts/*`. Next, it looks again at the post metadata and gets all the tags used. Once it has all the tags, pages for the tags are generated at `/tags/*`. That page lists all the posts with that tag. Scroll up and try it!

So how does the "Show MD", "Fancy Title", and Dark/Light theme toggle work? The key thing here is that all three of these are checkboxes. Yes, even the Dark/Light theme toggle is a checkbox. That toggle hides its checkbox and takes advantage of the fact you can click on a `<label>` with an appropriate `for` attribute to toggle a checkbox, and uses the `::after` psuedo-element to change the content between the moon emoji and the sun emoji, depending on the state of the checkbox.

What's so special about checkboxes? The `:checked` ([see MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/:checked)) property, that's what! With the `:checked` property, we can apply styles depending on whether a checkbox is checked. See the following, which scales the checkbox by 3x when the checkbox is checked: What's so special about checkboxes?

input[type="checkbox"] { input[type="checkbox"] {

transform: scale(1); transform: scale(1);
} }
input[type="checkbox"]:checked { input[type="checkbox"]:checked {
transform: scale(3); transform: scale(3);
} }
``` ```
And because of the `a ~ b` (select selector b *after* selector a) and `a + b` (select selector b *immediately after* selector a) CSS selectors, we can change the properties of other elements. Unfortunately, there doesn't seem to be a pure CSS way to change the style of elements *before* the checkbox. There are ways around this, like putting the checkbox before the desired element in the code, but using `position: relative`, `position: absolute`, and other ways to make the checkbox visually look like it is after the desired element. I didn't really want to do that though, so you can notice that all the checkboxes on this website are before the element whose style they change.

A month or two ago, I "translated" [Ryuji](/posts/ryuji-docs), originally written in Typescript, into Rust.
I mostly wrote this to practice writing Rust, which I guess is a success. In this project, I've somehow once again avoided properly figuring out how to use lifetimes (hey, I tried). That's a victory for my brain but probably a failure for my Rust skills.
The source code is on [Github](https://github.com/jetstream0/ryuji-rust) and the auto-generated documentation is on [docs.rs](https://docs.rs/ryuji-rust/latest/ryuji_rust/). If, for whatever reason, you actually want to use Ryuji-Rust, it might be helpful to look at the [tests](https://github.com/jetstream0/ryuji-rust/blob/master/src/lib.rs), [example](https://github.com/jetstream0/ryuji-rust/tree/master/example), and the [Ryuji docs](/posts/ryuji-docs) page.

Recently, I've been working on a discord bot game for Beer Goggles NFT on Algorand. > **Update, October 2023**: I realize I was being kind of an idiot. In retrospect, what I should've done was have the MongoDB operation be a `replaceOne` that *only* modifies if the damage dealt is under the hp - so it would only be possible for a write to happen for one player even if two click at the same time. Then, I could check the return value of the `replaceOne` (which tells me whether the operation modified documents or not), and discard any fake winners whose clicks did not result in the database being modified. Beware that if you continue reading, you will encounter a very stupid solution to a problem.
The specifics aren't too important, but essentially the game works like this: A game is started by an admin, and a secret number of hp is specified. Then, players can click a button, and depending on the amount of NFTs they hold, they will do "damage". All the damage is added up, and the person who crosses the secret number of hp wins. Like a pinata. Or in the case of our bar themed game, a huge opaque mug of beer that is passed around, with the goal being the one to finish the drink. Recently, I've been working on a discord bot game for Beer Goggles NFT on Algorand.
Now, onto the more technical details. Whenever a user clicks the button, the callback for the button interaction event is run.

Like a pinata. Or in the case of our bar themed game, a huge opaque mug of beer that is passed around, with the goal being the one to finish the drink.
First, the program reads the database (MongoDB) and sees the current hp left for the current game. If the current hp is less than zero, or a game over flag is set, the user is notified that the game is over, and the click does nothing. If that isn't the case, it then calculates the damage done by the player (a combination of luck, the amount of NFTs they hold, and powerups they bought). The damage done is subtracted from the hp (new hp is written to the db). Finally, the program checks if the user has won (hp at or under 0). If so, it ends the game and announces the winner. Now, onto the more technical details. Whenever a user clicks the button, the callback for the button interaction event is run.
However if one player clicks, then another player clicks milliseconds after, in some cases there just hasn't been enough time for the db writes to take place, and so there can be multiple winners.

This is **bad**!!!
The main problem is, the two functions being run at the same time aren't aware of the existence of the other, and can't communicate to ensure only one winner. I tried a variety of methods, like adding another check to make sure the game didn't end already. None of it worked, unfortunately. ![This is kinda bad, a screenshot of two winners](/images/screenshot_double_win.png)
What did work though, is adding a random delay using `setTimeout` and `Math.random`, if the program thought the user won (`hp <= 0`). After the random delay, a global array variable would be looked at. If the array was empty, then the winner would be announced, and something (doesn't matter what) would be added to the array. I'm not sure why I made it an array, and not an dictionary, but it worked^tm^ (only one game can be run at a time, but if the bot had multiple games running, a dictionary with the keys as game ids set when the winner was found would work better). I probably had a good reason at the time, or at least fooled myself into thinking I did. Anyways, so if there was another winner about to be announced, the program would see the array was not empty, and not announce the extra winner(s).

Technically, if the random delay was the same or only a few milliseconds different, the global variable could be looked at the same time, and two winners (or more) could still be announced.
