Readme
Wisp: Whitespace to Lisp
define : hello (define (hello)
display "Hello World" ⇒ (display "Hello World"))
define : fibonacci n (define (fibonacci n)
let rek : (i 0) (u 1) (v 1) (let rek ((i 0) (u 1) (v 1))
if : >= i {n - 2} ⇒ (if (>= i (- n 2))
. v v
rek {i + 1} v {u + v} (rek (+ i 1) v (+ u v)))))
Wisp turns indentation based syntax into Lisp. The conversion is homoiconic, generic, and backwards-compatible. It is inspired by project readable, but tries to keep itself simple (and stupid: just add parens for indentation).
More information is available on the wisp-website, and code in the wisp-repository.
For a short presentation, see Why Wisp?
Note that this is full-fledged scheme, with all its capabilities like hygienic macros (programmable syntax!) and full tail recursion.
Requirements
Setup
From the repository:
- Get wisp:
hg clone http://draketo.de/proj/wisp (needs Mercurial)
- Bootstrap:
cd wisp && autoreconf -i && ./configure && make
From a release:
Install systemwide with ./configure --datarootdir=/usr/share && sudo make install, then you can run guile --language=wisp anywhere. Install in your home folder with ./configure --datarootdir=$HOME/.local; make install. Use guile -c '(import (language wisp spec))' to get rid of auto-compile errors.
Run tests with make check. Distribute your own version with make distcheck.
If your Guile is installed in your home, you might need to use ./configure PKG_CONFIG_PATH=$HOME/.local/lib/pkgconfig/ and make distcheck PKG_CONFIG_PATH=$HOME/.local/lib/pkgconfig/
The same might apply for Guile in /usr/local/: you might have to use PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
Usage
- Preprocess files:
guile ./wisp.scm infile.wisp > outfile.scm
- Wisp at the REPL:
guile -L . --language=wisp # in the wisp-folder
- The files in examples/ show how to make executable wisp programs.
Wisp and curly infix (SRFI-105)
Wisp treats braces "{}" the same as parentheses "()" and square brackets "[]", so you can use it with curly infix (SRFI-105) to get more customary math expressions. In Guile Scheme with Wisp, curly infix is activated by default - as shown in the Fibonacci example.
If you want to use a curly-infix expression starting a line, you have to prefix it with a dot:
. {1 + 1}
; = 2
Notes
Standardization: Wisp is standardized as SRFI 119.
