Call python from Common Lisp

This is a fork of bendudson/py4cl.

Github Pages

Detailed documentation is available on github-pages (could be a bit outdated).

Releases

Check the Releases section. That said, if you are looking for stability, look at py4cl and not py4cl2, at least not in 2021. You may use py4cl2 on use-and-throw projects, or use it without using "edgy" features (not yet classified).

Contribution and PRs

Please test using py4cl2-tests.

Quick Demonstration

(ql:quickload :py4cl2 :silent t)

(py4cl2:defpymodule "numpy" nil :lisp-package "NP")
(py4cl2:defpymodule "scipy.integrate" nil :lisp-package "INTEGRATE")

;; Integrate some ODEs
(defparameter *data*
  (integrate:odeint 
   :func (lambda (y time) 
           (list (aref y 1)       ; dy[0]/dt = y[1]
                 (- (aref y 0)))) ; dy[1]/dt = -y[0]
   :y-0 #(1.0 0.0)   ; Initial state
   :t (np:linspace :start 0.0 :stop (* 2 pi) :num 20)))
                                        ; Vector of times

; (array-dimensions *data*) => (20 2)

;; Make a plot, save and show it in a window
(py4cl2:defpymodule "matplotlib.pyplot" nil :lisp-package "PLT")

(plt:plot *data*)
(plt:xlabel :xlabel "Time")
(plt:savefig "result.pdf")
(plt:show)

Great thanks to Ben Dudson for starting this project, and documenting it enough to make it more-buildable!
