Strings

• Strings/Chars in lexer.mll and parser.mly -- multi-line strings?
• EString, ImmString
• Allocation
• GC: need to sweep strings (copy/paste tuple case again?)
• Char doesn't need a whole word
• get at index for strings
• Concatenation -- str1 ^ str2
• charToInt, intToChar | chr, ord
• String equality
• slicing
• Build out a string library
  • toString
  • split
  • comparison (but not defined as primops)
  • isPrefix
• escape sequence printing
• test a bunch of random special characters via ascii code and direct usage

Compilation

• Readdress the tagging pattern
  • use the LSB of arity to delineate
• Create and store strings on heap (return the heap_reg, ofc)
• Tuple indexing and other existing things must not accept strings
• Tag error checks for prim ops -- concatenation needs to check for string tag for left and right

Implement the functionality to demo

• Caesar cipher (input, string get at index, len, ord, chr, concat)
• reverse a string [::-1] (input, slicing)
• Pig Latin (input, slicing, len, concat, split)
• Sort a list of strings (input, comparison, split)

Testing

• Make sure existing prim ops do/don't allow strings appropriately - D

Presentation

• write substantial documentation - D
• Write down where each string operation in STRINGS.md lives within input/ dir - D
• Write some agenda notes
• Highlight important design decisions (see DECISIONS.md) - D
• Well-defined and Heavily Detailed README - D then J -- usage examples -- supported language features -- high-level description -- snake puns (maybe a snake starting with S?)
• revive test.ml - D
• Investigate GC seg faults
• revive existing integration tests - J
• write new integration tests - J

Other Ideas

• Support strings as input
