Pico is a two instruction bf minimisation with somewhat complex semantics for each of its two symbols
[, ]
The first symbol represents a call to a function that takes a variable number of copies of itself as arguments.
This repo consists of two transducer programs:
- pico2python
- bf2pico
Written in four different languages:
- shell script: pico2python.sh | bf2pico.sh
- bf: pico2python.bf | [bf2pico.bf] PENDING
- pico: pico2python.pico | [bf2pico.pico] PENDING
- python: pico2python.py | [bf2pico.py] PENDING
It also includes:
- pico.sh : A standalone bash shell pico interpreter which uses Python to execute the transduced pico code.
Transduce and run a bf program:
./bf2pico.sh examples/hw.bf | ./pico.sh
Transduce and run a bf self interpreter (dbfi.b), with input hw.bf:
python <(./bf2pico.sh examples/dbfi.b | ./pico2python.sh ) < <(echo -e "$(sed 's/\(.\)/\1\n/g' examples/hw.bf)\n!")
or
echo -e "$(sed 's/\(.\)/\1\n/g' examples/hw.bf)\n!" | ./pico.sh <(./bf2pico.sh examples/dbfi.b)
or
./pico.sh <(./bf2pico.sh examples/dbfi.b) < <(echo -e "$(fold -w1 examples/hw.bf)\n!" )
or
./pico.sh <(./bf2pico.sh examples/dbfi.b) < <(echo -e ",[,.]\!It's a cat program" | fold -w1 )
./pico2python.py < <(echo -e "$(fold -w1 pico2python.pico)\n")
./pico.sh pico2python.pico < <(echo -e "$(fold -w1 pico2python.pico)\n")
TODO: Having the prompt > mixed in with the output is a problem. Find a neater solution for accepting input.
