This folder contains some example scripts in the pep script language. Scripts
have the file extension ".pss". These examples can be run using the
interpreter and debugger ("pep") or by translating to java, c, go, python,
ruby etc and then (compiling and) running
The interpreter is implemented in c at /books/pars/object/pep.c The main
documentation file is here href="net/books/pars/pars-book.txt">net/books/pars/pars-book.txt
examples can be run with the interpreter by typing
pep -f eg/script.pss input-file
or
pep -f eg/script.pss -i
Examples can be translated into java,tcl,ruby,python,c,go by running
the translation script
translate into go, compile and run
pep -f tr/translate.go.pss eg/script.pss > eg/golang/script.go
cd eg/golang/; go build script.go
echo "" | ./script
This folder to contains examples of the capabilities of the pattern parsing
machine.
Todo
A tiny basic interpreter/translator.
A "logo" parser/interpreter with turtle drawing.
The logo parser has an extra challenge... namely that it is necessary
to know the signature of a user defined function in order to
parse it. eg
p1 p2 10 20
This could be parsed as "p1 (p2 10) 20" or as "p1 (p2 10 20)"
Some examples
eg/exp.tolisp.pss
converts basic arithmetic expressions to a lisp format
eg/json.check.pss
checks json text input for grammatical correctness
