Roughly, the heap size is how much memory Java isĪllowed to use when running your program. The most important parameters for you to know about right from the beginningĪre -Xms and -Xmx, which set the initial and maximum Only parameter you'll need, but for more advanced usage you might need to dig aīit deeper into the possibilities. For most simple applications ofĬommand-line Processing.py, the -jar parameter is probably the Which parameters to pass to the interpreter. When you run java on the command line, it's up to you to know (see previous section for further instructions).Īny syntax errors or runtime exceptions in your program will be printed to Something like 'java' is not a recognized command or java:Ĭommand not found, then you may not have successfully installed Java Typed the command as specified, spaces and all (note that there's a spaceīetween java and -jar and that there's only one If the window did not appear, then something went wrong. The examples.py folder contains a number ofĮxample scripts to get you started.

Program working, you can run any Processing.py program on the command line With the mouse_follow.py sketch up and running.

Little bit of code that reads and executes the Python file specified on theĪfter typing the above and hitting return, you should see a window appear Processing-py.jar file contains all of Processing.py along with a The interpreter to run the code in the given JAR. The command above runs the Java interpreter ( java), and tells Now, type the following: java -jar processing-py.jar mouse_follow.py Line session (with, e.g., Terminal on OSX or Command Prompt in Windows) andĬd to the directory with the sketch and the Save the file in the same directory as the. Now youĬan use your favorite text editor to write a Processing.py sketch. jar file in a new directory for your project. Installed Java and decompressed the processing-py.jar file, put aĬopy of the. Decompress the file, making note of the location of the Scripts and some utility programs for running Processing.py on its own, for These files contain the Processing.py JAR file along with some example The appropriate link according to your platform: You'll also need to obtain the standalone version of Processing.py. Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_202-b08) You should see some output that looks like this: java version "1.8.0_202" Please don't use it (and then complain when things break).Īfter installing, ensure that you can run Java by typing the following on

Later versions of Java (9, 10, et cetera) don't work either. From the Processing Build Instructions: Other versions of Java are not supported.

For maximum compatability with processing, you'll need to install Java 8 - specifically, we recommend JRE 8u202 from Oracle. In order to run Processing.py from the command line. These instructions are tested on OSX El Capitan, but should work on other Or maybe (like me) you just prefer working on Over how your application gets packaged for easier interoperability with other tools that There are some scenarios in which you might want to use the command line: forĮasier integration with collaborative version control tools for more control It for writing interactive applications from sketch to finished product. Why use the command line? The PDE is great, of course, and many people use But Processing.py also provides a way for you to writeĪnd launch sketches from the command line. Which allows you to write Processing sketches in the PDE using the Python Most of the material online about Processing.py is oriented to Python Mode, This work is licensed under a Creative CommonsĪttribution-NonCommercial-ShareAlike 4.0 International License.
