This is a fork of NodeBox 1.

The current version is 1.10.1

Download the compiled app from the github releases.

2022-03-28 App only release includes version for M1. This was generated on an iMac with 11.6.3 and has only been tested to run the examples. Not the Library.

2021-10-26 The Python 3 transformation is nearly complete.

2021-06-20 A transition to Python3.8 is underway. I intend to keep the source py2/py3 compatible as long as possible or at least as long as I care.

2018-05-05 With version 1.9.31 OS X 10.9 is the minimum OS version needed to run NodeBox. Prior Versions should run on 10.6 and above.

As of 2017-05-17 the 32-bit version has been dropped. Please write up an issue if you need one.


The download includes the NodeBox-Library. When first starting NodeBox, go to the preferences and set the Library folder to the included folder.

Differences from the official version:

  1. Additional Commands (they were already in the original source but not active)

    1. angle(x0, y0, x1, y1) The angle of line (y0,y0,x1,y1)
    2. distance(x0, y0, x1, y1) The distance between points (x0,y0) and (x1,y1).
    3. coordinates(x0, y0, distance, angle) The point at dintance and angle from point(x0,y0)
    4. `reflect(x0, y0, x1, y1, d=1.0, a=180) Too complicated. Watch the example file Example coordinates
    5. isqrt(n) = 1 / sqrt(n)
  2. Different behaviour:

    1. size(0,0) sets size to size of main screen

    2. Can open shoebot ('.bot') files. Runs many of the shoebot examples. Incompatibilities exist.

    3. Colors can be hex strings.

      • '#f00' or 'f00' for red
      • '#f008' or 'f008' for red with alpha=0.5
      • '#00ff00' or '00ff00'for green
      • '#00ff001a' or '00ff001a' for green with ca. 10% alpha
    4. Variables

      • New var type: MENU
      • The var keyword has 2 new parameters: handler=None and menuitems=None
      • All var types now can have a handler: NUMBER, TEXT, BUTTON, BOOLEANand MENU.
      • The difference is: When a handler is set, only that function is re-run. The whole script otherwise.
      • The MENU var needs a handler.
      • The handler=one or two argument-function to be called. If 1-arg: (value,). If 2-arg: (value, name).
      • menuitems = list or tuple of strings.
      • See example file "examples/New Functions/Example var menu"
  3. Uses Python 2.7.16 and PyObjC 5.3 or Python 3.8.12 and PyObjC 6.2.2

  4. Is self containend so it does not depend on an installed Python and therefore runs on different OS versions.

  5. Builds without Xcode ( python py2app )

  6. Uses a different and bigger icon (512px)

  7. Has many additional examples. See folders Escher, geometry/Convex Hull and New Functions .

  8. New function filelist( folder or list of folders, pathonly=True ) (v1.9.19)

    • Returns a path generator
    • If pathonly is False, it returns a (path, size, lastmodifieddatetime, oct(mode)) generator
    • The Following filenames are ignored: any name starting with '.', any name containing any of: '\r\n\t'.
  9. New function imagefiles( folder or list of folders, pathonly=True ) (v1.9.19)

    • Same parameters and restrictions as filelist plus:
    • filters file extensions for ".pdf .eps .tif .tiff .gif .jpg .jpeg .png"
  10. New function fontnames() (v1.9.20)

    • Returns a list of names from NSFontManager.sharedFontManager().availableFonts(). Fontnames starting with '.' are ignored.
  11. New function fontfamilies(flat=False) (v1.9.20)

    • Return a dict with [FontFamily][STYLE]-> FontRecord
    • if parameter flat=True returns a list of FontRecord
    • A FontRecord has the following attributes:
      • psname - the postscript name, which can be used for font()
      • familyname - the font family name
      • style - the style name
      • weight - the font weight
      • traits - an int that represents the fonts traits
      • traitnames - the traits converted to a list of names: (italic, bold, unbold, nonstandardcharacterset", narrow, expanded, condensed, smallcaps, poster, compressed, fixedpitch, unitalic)
  12. New graphics primitive arc(x, y, r, startAngle, endAngle)

    • Draws an arc between startAngle and endAngle with center at (x,y) and radius=r.
  13. New function say(txt, voice=None, outfile=None, wait=True) (1.9.26). Say txt in voice. If voice is None, the default voice is used. If outfile is a valid path, the text will be saved as an AIFF file (1.9.27).

  14. New function voices()(1.9.26). List all voices in a format that can be used by say().

  15. New function voiceattributes( voice ) (1.9.26). return a dict with all attributes about that voice.

  16. New function anySpeakers() anySpeakers(): Return a bool if ANY application is currently speaking.

  17. New Examples subfolder "New Functions" which contains examples for the new functions.

  18. New function circle(cx, cy, rx, ry=None, draw=True) Draws a circle in current style with center = (cx, cy) and radii rx and ry. For better shoebot compatibility.

Since 1.9.21 the adapted Nodebox library is now included in the download. Open Nodebox, go to preferences and set the Library folder to the included one "NodeBox-Library". The repository is here: Library.

The original README:


NodeBox is an application used in graphic design research. It provides an interactive Python environment where you can create two-dimensional graphics. NodeBox scripts can create PDFs or QuickTime movies that can contain anything from simple geometrical shapes to fully-fledged bitmaps, vector images and text.

NodeBox is mostly meant to design and explore generative design and animation. It features several ways to manipulate parameters inside of a program: it contains an interface builder and an on-the-fly value changing gizmo called the throttle.


NodeBox itself is written by Frederik De Bleser. ( The NodeBox manual is written by Tom De Smedt. (

NodeBox is a fork of DrawBot ( by Just van Rossum (, which is released under a MIT-style license.
