Constants

• kT - BF command set
• kṗ - List of all bracket pairs - [(),[],{},<>]
• kṖ - All brackets nested - ([{<>}])
• kg - Phi
• kS - Amogus (ඞ)
• k₂ - 2^20
• k₃ - 2^30
• k∪ - lowercase vowels with y
• k⊍ - uppercase vowels with y
• k∩ - both cases of vowels with y
• Þo -Infinite list of ordinals
• Þc - Infinite list of cardinals
• Þp - Infinite list of primes

Flags

• #407
• #408
• t - Lists are truthy if any item is truthy, else falsy
• #456
• #455
• 2 - Default lambda arity = 2
• 3 - Default lambda arity = 3

String stuff

• øb = Enclose in ()
• øB = Enclose in []
• øḃ = Enclose in {}
• øḂ = enclose in <>
• øβ - Are brackets ((),{},[],<>) balanced?
• ø↳ and ø↲ = custom left / right padding
• øĿ - Ring translate
• øv - Is_vowel - handles like C for multichar strings
• øċ - Is_uppercase - handles like C for multichar strings, 1 if char is an uppercase ASCII letter, else 0
• øM = Palindromise (don’t duplicate middle) with ascii-art swap mappings

Number stuff

• ∆i - nth-digit-of-pi
• ∆ė - nth-digit-of-e
• ∆I - First n digits of pi
• ∆Ė - First n digits of e
• ∆f - nth-fibonacci-number
• ∆ε - Evaluate polynomial equation with coefficents and variable
• ÞB - Array of random bits to length n
• ∆Z - zfill - prepend 0s to a until it’s length b

Other stuff

• #399
• Þu - All_unique
• ÞẊ - Cartesian power
• Þx - Þ× but with replacements
• Þf - Flattento a certain depth
• øṖ - All partitions of a string
• #401
• ÞC - Cut into chunks of specified length (stolen from osabie)
• Þ< - All of a list that are less than a certain number (Assume increasing, stop as soon as you find a value ≥ that number)
• Þǔ - Untruth - A boolean array with 1s at the elements in a, and 0s everywhere else(Stolen from Jelly)
• Þi - Multidimensional indexing - take an array of indices and index into a multidimensional array
• Þḟ - Multidimensional searching - find the first (multidimensional) occurence of a value
• #402
• #403
• #404
• #405
• Þm - Given list of dimensions, create a matrix with those dimensions, filled with zeroes
• ÞZ - Fill by coordinates - Given function + list, call with each (potentially multidimensional) coordinate of list, as list of integers, and insert result into corresponding location

Modifications

• Random choice from a number picks a random number between 0 and n, modifiable with mM flags
• İ vectorises fully on the right side - not erroring when given a nested list, instead going through every item
• ⌊ needs to play nice with strings not containing digits.
• øȯ should be able to take a list of strings to remove
• Modify Ẏ so if given an index to slice to greater than the length, repeat items until it’s at the required length.

@razetime Ah, I guess that’d work. Not the highest priority, though 😄.

@ysthakur I think it was meant to be a constant. So kṠ would return the string ඞ or something
