We have moved! Fysh-Fyve/fysh

This is fysh.

This is Steven.

><steven> ~

Steven has binary scales. } represents 1 and ) represents 0. Steven is valued at 0b101. (5 in decimal)

><steven> = ><})}> ~

Steven doesn’t give a flying fysh about scale direction. ≈ for variable assignment is cool with them too.

><steven> ≈ ><}({> ~

Steven is blind. You have the power to bless them with sight, but it's completely optional. (you can make them biblically accurate by giving them multiple eyes)

><steven> ≈ ><{({°> ~
><steven> ≈ ><{({o> ~

><steven> ≈ ><{({°°> ~
><steven> ≈ ><{({o°> ~

><steven> = ><{({°o°> ~

A school of fysh's value is equal to the sum of each individual member. This gives Steven a value of 0b101 = 0b100 + 0b001. (5 = 4 + 1)

><steven> ≈ ><{((°> ><(({°> ~

Sometimes fysh want to be different and swim the other direction. This takes away from the school’s value. This gives Steven a value of. 0b101 = 0b111 - 0b010. (5 = 7 - 2)

><steven> ≈ ><{{{°> <°)})>< ~

Fysh often get lonely. This loneliness causes fysh to meet new fysh and proliferate. This gives Steven a value of 0b101010 = 0b110 * 0b111. (42 = 6 * 7)

><steven> = ><{{(°> <3 ><{{{°> ~

Not every fysh story is a happy one. At times, separation is unavoidable, and their division breaks their heart. This gives Steven a value of 0b101 = 0b11001 / 0b101. (5 = 25 / 5)

><steven> ≈ ><{{(({°> 💔 ><{({°> ~
><steven> = ><{{(({o> </3 ><{({o> ~

Fysh are often abducted and forced into fyshbowls for terrestrials' amusment. This isolates the fysh and makes them sad. Fyshbowls are represented by ( ). This gives Steven a value of 0b101 = 0b101 / (0b101 - 0b100). (5 = 5 / (5 - 4))

><steven> ≈ ><{({°> 💔 ( ><{({°> <°}))>< ) ~

As life goes on, we learn from our mistakes and improve. Steven’s self help journey allowed them to grow an extra tail, incrementing their value by 1.

>><steven> ~

Sometimes we feel like a fyshup, a failure. And that's ok, it’s a part of being fysh. However for some fysh, this feeling is too much to handle and is internalized. They haven’t received the emotional support they need and have gone on a downward spiral, causing them to feel worthless. They begin to retreat and try to swim away in the opposite direction causing their value to decrement by 1.

<steven><< ~

BEDMAS/PEMDAS has been taught to humans for over a century. But what about fysh? Fysh have a different way of doing things. Introducing FISHS: Fyshbowl, Increment, Species reproduction, Heartbreak, and School of fish ( (), >><>, ♡ , 💔, ><> <>< ). This gives Steven a value of 0b10101111 = (0b11001 + 1) + 0b110 * 0b11001 - 0b1100 / (0b110 + 0b110). (175 = (25 + 1) + 6 * 25 - 12 / (6 + 6))

Sometimes Steven fyshs up and throws an error. This can be done using two WTF (What The Fysh) fysh encompassing a string.

Navigator fysh are used to guide the reader through the code. They are represented by ><//>. (comments)

><//> What's cookin good lookin?

Sometimes, the journey through the sea of code is long and dark. In these cases, multiline comments are used to provide a more detailed explanation of the code. They are represented by ></*> and <*\><. (multiline comments)

></*>
How to grill a fysh:
1. Catch a fysh
2. Grill the fysh
3. Eat the fysh
<*/><

This is a grilled fysh. It generates a random signed 32-bit number that determines the doneness of the fysh.

Not all fysh are created equal. But sometimes they are. We can check using ≈≈ or ==.

><steven> ≈≈ ><theFysh> ~
><steven> == ><theFysh> ~

Sometimes we want to check if two fysh are different. This can be done using ~≈ or ~=.

><steven> ~≈ ><theFysh> ~
><steven> ~= ><theFysh> ~

Tadpoles are fysh too. They swim towards bigger fysh (they like the danger) and are represented by ~o or o~. Here we are checking if Steven is bigger than 5 and less than 7 respectively.

><//> Greater, Less than (respectively)
><steven> o~ ><{({°>
><steven> ~o ><{{{°>

><//> Greater, Less than or equal to (respectively)
><steven> o~≈ ><{({°>
><steven> ~o= ><{{{°>

><//> Greater, Less than or equal to (shorthand)
><steven> o= ><{({°>
><steven> ≈o ><{{{°>

Steven is experiencing an existential crisis. They are questioning the very fabric of reality. Are they real? Are they a simulation? Are they a fysh? Are they a human? Are they a fyshuman? Are they a human fysh? Are they a fyshy human? Are they a humany fysh? Are they a fyshy humany? Are they a humany fyshy? Are they a fyshy humany fysh? Are they a humany fyshy human? Are they a fyshy humany fyshy? Are they a humany fyshy humany? Are they a fyshy humany fyshy human? Are they a humany fyshy humany fysh? Are they a fyshy humany fyshy humany? Are they a humany fyshy humany fyshy? ...

So steven is looking for the truth. If steven is real and they found the truth, they are happy. (Steven && theTruth)
Steven would also be happy if either they are real or if they found the truth. (Steven || theTruth)
But then steven thought about it and thought "hey it would be kinda cool if I wasn't real" and are only happy if they are not real. (!!Steven)

Steven is bored and looking to have their bits rearranged. At Fysh, we're here to help! We have provided Steven with a variety of tools and bitwise manipulations to satisfy their bit busting needs: AND (&), OR (|), XOR (^), NOT (!). For those moments when they're feeling particularly adventurous, they might even consider the logical shift left (<<) or logical shift right (>>) operators.

If statements are happy since they're the condition you're looking for. It helps validate them and improve their self-esteem. ><(((^>
Else statements feel like they're the last resort, an afterthought. This makes them feel unimportant and sad. They are represended by a dead fysh ><(((*>
Else if statements are the middle child, they're not the first choice but they're not the last either. They're the middle ground. They are represented by both a happy and a dead fysh ><(((*> ><(((^>

Conditions are encapsulated within a fysh tank [ ], with ><> and <>< encapsulating the conditional heart.

A fysh tank [ ] is also used for an array of fysh that is seperated by fysh food -.

><steven> ≈ [><({(°> - ><({(°>] ~

These fysh tanks can be traversed using a fysh.
(Steven returns the element at index 1 (0-indexed))

><steven>[><(({°>] ~

To define a function or SUBroutine, use a submarine >(funcNameHere) along with any parameters ><param>. By default, last expression in the subroutine acts as the return value. To explicitly return a value, use a baby squid <~ or 🦑.

>(submarine) ><param1> ><param2> ><param3>
><>
	<~ <fysh>< ~
<><

To call a subroutine, put the submarine in a fysh tank along with its arguments in any order. If two params are next to each other, seperate them with a fysh food -.:

[><fysh1> >(submarine) ><fysh2> - ><fysh3>] ~

To interact with the ocean floor (GPIO), use the anchor.
