iogii ⸱ Nitty Gritty ⸱ Ops ⸱ Quick Ref ⸱ Source ⸱ Online Interpreter

Source

To run iogii save the "1 File" from the latest release (below) as iogii and chmod +x it, then run iogii <filename.iog> (it is standalone ruby code with no dependencies).

You can also download "All Source" and run cd src; ruby main.rb <filename.iog>. This includes the original source files, all tests, and site generation code.

The current version is compatible with Ruby 2.7.2 - 3.1.2 (and likely beyond in both directions). And if you use Haskell code generation, it is compatible with GHC 8.10.7.

I am not using github due to them not respecting licenses by training LLMs on code without crediting said code when used in a response.

Planned Features

• Allow the rotation trick to be used inside nested functions to eliminate the need for !. This could allow functions to be more concise and obsolete [ ] / etc. too. I do not yet have an intuition for how this will work with implicit args and >, it will be extremely difficult to get right.

Releases

0.2 (Alpha) - Dec 11, 2024

• 1 File
• All Source
• Website Snapshot

Changes:

• Clarified reshape behavior, explained in new Ops page.
• Fix bug with , following token that was split up, e.g. nJ,
• Add Graphviz visualizations to online interpreter.
• Support Haskell code generation (~50x speedup + no stack overflow limit)
• Remove pp
• show now prints like Haskell would
• Rename nuke to del
• Remove regex match
• Add charClass op
• Output chars mod 256 rather than error if out of range
• expand does not return the initial value now (thanks UnrelatedString for the suggestion).
• Change transpose to insert default values so that truncation is never needed.
• Support input from command line args after --.

0.1 (Alpha) - Nov 7, 2024

• 1 File
• All Source
• Website Snapshot

Changes:

• Add more string ops
  • charRange ^
  • uppercase U
  • lowercase L
  • parts P (split on whitespace)
  • chr |, (convert int to char)
  • match + to match regexes.
• Allow unterminated strings.
• Allow implicit args.
• Add auto parsing of input.
• @ also sets input if none present.
• Make pow ^ work more consistently for negative numbers and not overflow for large numbers.
• Remove ops: nfoldProd p, and y
• Add ops: pad p, index ., get g
• Rename ops:
  • chunkWhen . → \
  • transpose \ → p (pivot). So that it can be unvectorized and also provide nice overload for prod.
  • digits \ → p (it's like transposing a string)
  • last z → l
  • len l → q (quantity)
  • equal q → =
  • assignment = → ~
  • generate g → K (kCopy), no longer generic
  • if → y (yes no)
  • sum _ → #
  • negate / read ~ → _
  • pow10 Z → H (hyper)
  • sqrt H → u (unsquare)
  • toBase # → D (digitize)
  • fromBase #, → W baseFrom (base was). Note that arg order is also swapped - necessary to have vectorized overload.

0.0 (Alpha) - Oct 29, 2024
