ALAGUF

From Esolang

ALAGUF is a language made by User:iconmaster.

It is an acronym for At Last, A Greatly Useful Funge.

It is a fungeoid that is designed to be easy to use and yet powerful.

[edit] Syntax

The program starts at the last '0' it finds in the program, going Right. It uses stacks to save data. There is also a StackStack, which is used to contain multiple stacks. There are two data types: Numbers and Strings. It skips any spaces or letters. The possible commands are as follows:

< Go Left.
> Go Right.
^ Go Up.
v Go Down.
' Anything between two ' characters are pushed onto the stack as a number.
" Anything between two " characters are pushed onto the stack as a string.
+ Basic Stack Commands:
→ Increment the stack's top value.
← Decrement the stack's top value.
↑ Pushes 0 onto th stack.
↓ Pops the top value off the stack.
- Basic stack mods:
→ Rotate the stack once to the left.
← Rotate the stack once to the right.
↑ copy the top value on the stack.
↓ clear all values on the stack.
* Math:
→ Subtracts the two top values and pushes it onto the stack.
← Adds the two top values and pushes it onto the stack.
↑ Multiplies the two top values and pushes it onto the stack.
↓ Divides the two top values and pushes it onto the stack.
( starts a loop.
) loops back if the top value is not 0.
! ends the program.
= Boolean commands:
→ pops the two top values and pushes 1 if they are equal, or 0 if they are not.
← pops the two top values and pushes 0 if they are equal, or 1 if they are not.
↑ pops the two top values and pushes 1 if the first is less than the second, or 0 if they are not.
↓ pops the two top values and pushes 1 if the first is greater than the second, or 0 if they are not.
& StackStack Commands:
→ Delete the current stack in the StackStack.
← Insert a blank stack below the current stack in the StackStack.
↑ Move up one in the StackStack.
↓ Move down one in the StackStack.
@ Output Setup:
→ Decrements the x display pointer.
← Increments the x display pointer.
↑ Decrements the y display pointer.
↓ Increments the y display pointer.
# I/0:
→ Pushes the character pointed to by the display pointer on the screen.
← Pops the top value off the stack and displays it at the place pointed to by the Display Pointer.
↑ Pushes the current key pressed. Returns 0 if no key is pressed.
↓ Asks the user for a string, and pushes the user's input.
$ Bridge.
% Logic:
→ Pops two values, performs boolean AND on them, and pushes the result.
← Pops two values, performs boolean OR on them, and pushes the result.
↑ Pops two values, performs boolean XOR on them, and pushes the result.
↓ performs boolean NOT on the top value of the stack.
? More Math:
→ Pops two values, divides them, and pushes the remainder.
← Substring.
↑ Pops two values, does an exponant on them, and pushes the result.
↓ Negates the top value on the stack.
/ rotates clockwise.
\ rotates counter-clockwise.
_ goes up if the top value is 0, goes down otherwise.
| goes Left if the top value is 0, goes Right otherwise.
` Files (well, mostly):
→ Sets the top value to either a string or a number, depending on the var's type.
← Saves a file. The top value is the file's name, the second is the value to be stored.
↑ Loads a file. The top value is the file's name.
↓ Pushes a 1 if the file specified by the top value exists, 0 otherwise.
1 Pushing:
→ Changes the top value between an ASCII character and its number.
← Pushes the size of the stack.
↑ Pushes the number of stacks in the StackStack.
↓ Push your currnet position.
2 Misc screen ops:
→ Pushes the x display pointer.
← Pushes the y diaplay pointer.
↑ Pops a value, and sets the x display pointer to it.
↓ Pops a value, and sets the y display pointer to it.
3 More StackStack Ops:
→ Move the current stack down one in the stackstack.
← Move the current stack up one in the stackstack.
↑ Pops the top value and pushes it onto the stack above it in the StackStack.
↓ Pops the top value and pushes it onto the stack below it in the StackStack.
4 Misc:
→ Pops a value and pushes a 1 if the value is a string, 0 otherwise.
← Pops a value and pushes a 0 if the value is a string, 1 otherwise.
↑ Pushes the StackStack pointer (what stack you are using in the StackStack.).
↓ Like Inserting a Stack (See & going left), but it copies it.
5 Clears the screen.
6 Waits for a key.
7 Sets the x display pointer to 1.

Note that the commands with four arrows next to them are direction-dependant commands; what they do depends on the direction they are going in.
