A brief discussion on the use of applications (in combination with PowerShell)

void setup() {
     String scriptPath = "C:\\path\\to\\script.ps1"; // PowerShell script path
     String param1 = "value1";
     String param2 = "value2";

     try {
         // Construct command
         String command = " -File " + scriptPath + " -param1 " + param1 + " -param2 " + param2;
         Process process = ().exec(command);
         // Read the output
         BufferedReader reader = new BufferedReader(new InputStreamReader(()));
         String line;
         while ((line = ()) != null) {
             println(line); // Print output to Processing console
         }
     } catch (Exception e) {
         ();
     }
 }

Note: The code is usedInputStreamReaderCome to readPowerShellInformation from script feedback.

2. PowerShell script call Processing-java

Run Processing scripts directly

Execute in PowerShell, and specify.pdeThe folder path where the file resides:

# Example: Run the Processing script with a specified path
 "C:\Processing\" --sketch="C:\path\to\yoursketchfolder" --run

If you frequently call the Processing-java program, you can set the system variables and add their directory address to the Path.

Pass command line parameters

Pass parameters to the Processing program in PowerShell and read in Processing code:

# PowerShell Command
 "C:\Processing\" --sketch="C:\path\to\yoursketchfolder" --run --args "parameter 1" "parameter 2"

Then pass in the Processing codeargsArray receiving parameters:

void setup() {
   size(400, 400);
   background(255);

   // Check whether there are parameters passed in
   if (null == args) {
   } else {

     if ( > 0) {
       for (int i = 0; i < ; i++) {
         println("Received parameter " + (i + 1) + ": " + args[i]);
       }
     } else {
       println("No parameters were received.");
     }
   }
 }

 void draw() {
   // Other drawing codes can be added here
 }

Parameters to be passed in can be placed separately in a string array for easy definition and management, such as:

# Define the parameters to be passed
 $parameters = "parameter 1", "parameter 2", "parameter 3"

 # Build a complete command
 $command = "$processingJavaPath --sketch=$sketchPath --run --args $($parameters -join ' ')"

Capture Processing output

Redirect Processing's console output to PowerShell variables and save:

$output = "C:\Processing\" --sketch="C:\path\to\yoursketchfolder" --run 2>&1
$output | Out-File -FilePath ""

Capture output：2>&1Make sure to capture all outputs when the command is running, including standard output and error messages, and store them in the $output variable.
Save logs: Save the output information, that is, the $output variable data to the log fileoutput.log, easy to view the results of command running and potential error information.

If the situation is simple, you can delete it2>&1Order.

Complex scenarios · Run multiple sketches and export applications

Suppose you need to automate the running of multiple Processing sketches and export the result to .exe to different folders. Write PowerShell scripts to implement:

# Define sketch list and output path
 $sketches = @(
     "D:\sketch\sk1",
     "D:\sketch\sk2",
     "D:\sketch\sk3"
 )
 $outputFolder = "D:\outputaa"

 # traverse each sketch and run
 foreach ($sketch in $sketches) {
     $outputPath = Join-Path $outputFolder (Split-Path $sketch -Leaf)
     New-Item -ItemType Directory -Path $outputPath -Force | Out-Null

     # Run the sketch and export
     processing-java --sketch=$sketch --output=$outputPath --force --export
 }

In Processing-java--outputParameters allow you to specify an output directory for storing the compiled files or exported files for sketches. It is useful when you need to organize built or exported files into a specific folder structure.

To use--outputParameters, you need to put them before the command that triggers the compile or export (such as--run、--export or--build). Here is a simple example:

processing-java --sketch="C:\path\to\yoursketchfolder" --output="C:\desired\output\folder" --run

Things to note

--outputThe specified directory cannot be the same as the sketch directory. Processing-java throws an error if you try to use the same directory.
If the output directory does not exist, Processing-java creates it where possible. In the above example, I manually created the directory to be output, so I need to add --force to make it ignore the existing folder and force the output file. The --force parameter must be placed before --export.
Relative paths can be used as output directory.

Summarize

By usingProcessing-java andPowerShell, can achieve more powerful automated deployment and cross-platform management functions. Of course, if it is for the creation and exhibition of digital media art, this combination will surely inject new ideas into creation and research and development, and can create and manage projects more efficiently.
