Snow* is a programming language based on the Assembly language syntax, and also its way of functioning.
Snow*'s environment contains 3 segments: mem which is the basic memory holder, limited to 256 values; temp which is a special segment, holding until 32 values, but whose content changes on each call; param which is a stack containing values used in system calls, for example, or which can be used in your own calls.
Easy ways to manage them are store, push, free and pop.
Example:
main: % Main entry point, absolutely needed
store[mem, 41] 'Hello, World!'
% In this case, we store the string 'Hello, World!' at the 41st index of the memory.
free [mem, 41]
% Now that we don't need it anymore, we can delete it
push[param] 'Pushed into the params'
% We can only push inside the params, because it is the only stack existing (and modifiable) in Snow*
pop [param]
% We may pop now, if we don't need them neither
int 0
% Don't forget this line, else your program will never stop
Yes, there is one. A website is hosted on github here. You will find every information you need (docs, tutorials, examples) there. If you have any question/request, feel free to ask them to me.
You will find me known as Меѕаblоо#5674 on Discord (please copy/paste, do not try to rewrite it).
main: % Still needed
rand[mem, 1] 0, 100
% We generate a random number between 0 and 100, stored at mem#1
repeat:
% Repeat until the number is found
push[param] 'Please input a number between 0 and 100:'
% Tell the player to input something
sys 1
% System call: 1 = output
pop [param]
% Good habit to pop once everything has been used
sys[temp, 1] 2
% System call: 2 = input. We then store the value at temp#1
stoi[temp, 1] [temp, 1]
% We convert temp#1 into an integer because `sys 2` gives it us as a string. If the conversion fails (invalid input)
cmp [mem, 1], [temp, 1]
% We compare mem#1 and temp#1
jwl lower
% if mem#1 < temp#1 we go to lower:
jwg greater
% if mem#1 > temp#1 we got to greater:
% else the number is the correct one
push[param] 'You found the correct number !\n'
% Let's tell the player he found the number
sys 1
% System call: 1 = output
pop [param]
% Good habit to pop once everything has been used
free [temp, 1]
free [mem, 1]
% Just delete the data because we don't need it anymore
int 0
% Also still needed
greater:
push[param] 'The number you are trying to guess is greater than the number you wrote.\n'
% We push this long string inside the parameters, so that we can output it
sys 1
% System call: 1 = output values in parameters. Be aware it takes them in reverse order
pop [param]
% Better to remove the value from the parameters before doing anything else
jmp repeat
% We go to repeat: because the number has not been found
lower:
push[param] 'The number you are trying to guess is lower than the number you wrote.\n'
% We push this long string inside the parameters, so that we can output it
sys 1
% System call: 1 = output values in parameters. Be aware it takes them in reverse order
pop [param]
% Better to remove the value from the parameters before doing anything else
jmp repeat
% We go to repeat: because the number has not been found
The indentation is not necessary. You can get rid of it. It just makes it a bit more clear what "block" is what.
If you want to ask me some questions, you can ask them directly to me on Discord. I will asnwer them with no problem.
If you want some features added, feel free to suggest them to me, or to someone who already talked to me before.
