Texteditor with a Pure LISP interpreter including operations of last S-expression evaluating and parenthese matching

Kilo with C version of PureLISP.sh

This software is Kilo texteditor with a Pure LISP interpreter, C version of PureLISP.sh, including operations of last S-expression evaluating and parenthese matching.

The source code to compile Kilo is supposed to be from a tutorial site, Build Your Own Text Editor Step 130, which is copied and arranged as kilo-BYOTE130.c and kilo-BYOTE130.h in this repository.

How to Compile and Use

• Docker image: docker run --rm -it ytaki0801/kplisp

Just type make to compile in this repository, on a standard POSIX system including C compiler and library with Make, as well as cc -DPURE_LISP_LIB -o kplisp kplisp.c kilo-BYOTE130.c PureLISP.c

Type ./kplisp <filename> to use. Parentheses matching is done automatically, Ctrl-e is to eval-last-sexp, Ctrl-s is to save and Ctrl-q is to quit.

For the PureLISP.sh specification, see PureLISP.sh repository and sample.plsh.

PureLISP.c

You can also compile PureLISP.c with PureLISP.h alone to use in a simple one-line-input REPL like the following. It is written in standard C specification only so enable to compile by not only GCC or Clang but also C compiler of Visual Studio Community or Tiny C Compiler.

$ cc PureLISP.c
$ ./a.out
S> (def reduce (lambda (f L i) (cond ((eq L nil) i) (t (f (car L) (reduce f (cdr L) i))))))
reduce
S> (reduce cons '(a b c) '(d e f g))
(a b c d e f g)
S> [Type Ctrl-d or Ctrl-c to exit]

TODO

• Full implemention of eval error handling in the interpreter.
