# Crochetable Cyclic Tag
A tool for generating and evaluating Turing-complete crochet patterns based on Emil Post's [tag system](https://en.wikipedia.org/wiki/Tag_system) computational model, and the esoteric programming language [Bitwise Cyclic Tag](https://esolangs.org/wiki/Bitwise_Cyclic_Tag).
## Usage examples
Help:
./cct.py -h
### Convert
Convert BCT to CCT:
./cct.py --bct "10 11 10 10 10 11 0 11 10 10 0 11 10 10 11 10 10 11 10 10 0 0 0 0" -t "Collatz Sequence"
Convert CT to CCT:
./cct.py --ct "010001;100;100100100;;;;" -t "Collatz Sequence"
Convert CCT to human followable crochet instructions for computaion-by-crochet (`--verbose`):
./cct.py examples/collatz.cct --verbose
### Evaluate
Evaluate CCT to crochet pattern symbols (Unicode to STDOUT):
./cct.py examples/collatz.cct
Evaluate CCT to SVG crochet pattern:
./cct.py --svg examples/collatz.cct
## Output example
### CCT code
[simple-triangle.cct](examples/simple-triangle.cct):
```
# Simple decreasing triangle swatch
1. Any sequence of sc / dc stitched onto an appropriately sized foundation chain.
2. std
3. dec-ss
4. std
Repeat from Row 3.
```
Produced with `./cct.py --ct ";" --title "Simple decreasing triangle swatch"`
### Verbose instructions
./cct.py examples/simple-triangle.cct --verbose
#### Simple decreasing triangle swatch
**Row 1** Any sequence of sc / dc stitched onto an appropriately sized foundation chain.
**Row 2** (std) work 1 sc into each dc, 1 dc into each sc until end of row; turn.
**Row 3** (dec-ss) 1 ss, then proceed as in the standard row until end of row; turn.
**Row 4** (std) work 1 sc into each dc, 1 dc into each sc until end of row; turn.
Repeat from Row 3.
### Evaluation of input
`0`: single crochet, `1`: double crochet (US crochet terminology)
./cct.py examples/simple-triangle.cct -i 111111
