WolframScript enables Wolfram Language code to be run from any terminal, Hacker News

WolframScript enables Wolfram Language code to be run from any terminal, whether or not a Wolfram kernel is available on the system.

With

WolframScript , users can decide where and how to run their Wolfram Language code. Along with configurable kernel and cloud settings, WolframScript includes a collection of convenience functions for a wide variety of tasks, including running pure functions with command-line input, calling cloud APIs and exporting data to any format supported by the Wolfram Language. Now you can run code in the Wolfram Cloud with wolframscript -cloud or with #! / usr / bin / env wolframscript -cloud in Unix shell scripts.

Examples

        

            

Evaluate the Wolfram Language code 2 2 on a local Wolfram Engine:

            

 
  $ wolframscript  -code 2   2             4  
                  

             

 Evaluate the Wolfram Language code 2   2 in the Wolfram Cloud: 
             
 
  $ wolframscript  -cloud -code 2   2             4  
                   

 Script files          

 Create a file to execute Wolfram Language code locally: 
         
             

 file.wls   

 #! / usr / bin / env wolframscript             Print [2 2] 
                   
 
  $  ./file.wls             4  
          
 Create a file to execute Wolfram Language code in the Wolfram Cloud: 
         
             

 file.wls   #! / usr / bin / env wolframscript - cloud                 Print [2 2] 

                   
 
  $  ./file.wls             4  
          
 Create a file that uses a command-line argument: 
         
             

 file.wls   

 #! / usr / bin / env wolframscript                 Print [ToExpression[$ScriptCommandLine[[1]]] ^ 2] 
                   
 
  $  ./file.wls 5             64 
            
 Create a file giving a function whose arguments come from the command line: 
         
             
 
 file.wls   #! / usr / bin / env wolframscript - function -signature City City                 Print [GeoDistance[#1, #2]] &                    
 
  $  ./file.wls "Champaign, IL" "Oxford, England "             Quantity [4010.4812837526256, Miles]

 Features 

         

 WolframScript introduces a wide variety of command-line interactions to best fit your scripting needs. 
         

	

			
	

			


		
			
			
					
			
		





              Run Code on the Command Line               

 Code can be passed to WolframScript directly on the command line with the  - code  argument, allowing the user to immediately display or redirect the output into a file. 
               Run Code from a File               
 Code can be run directly from Wolfram Language packages using the  - file  argument. 
              
 Create Executable Scripts               

 WolframScript can be used as a script interpreter, allowing for scripts to be written with the Unix  # !  syntax on systems where this is supported. 
               Run Functions from the Command Line              
  Pure functions  can be defined and executed using data and arguments from the command-line environment, allowing for easy ad-hoc sequential operations. 
              
 Simple Interaction with Input Streams               
 Data streamed into WolframScript is captured into the  $ ScriptInputString  symbol for easy processing of data either all at once or iteratively line by line. 
                  

             

 Use Cloud-based Computation               
 WolframScript is now capable of executing code using the  Wolfram Cloud . It can be configured to use either the public Wolfram Cloud or  Private Cloud . 
               Directly Access Cloud APIs 
             
 WolframScript is capable of parsing argument input and sending data directly to APIs hosted either in the Wolfram Cloud or Private Cloud using  APIFunction  
              
 Rich Export Formats               

 WolframScript is capable of converting and exporting its data to any 
 export format  supported by the Wolfram Language using the 
 - export  argument.               
 Now With Windows Support               

 WolframScript is now fully featured in Windows with support for the basic Windows command shell, MSYS or Cygwin. 
              
 Automatic Kernel Detection 
             
 WolframScript will automatically select the latest Wolfram kernel installed on the user's system (Windows, Mac). 
               

         Technical Information 
            WolframScript supports x 823 and x   systems running Windows, Mac or Linux. ARM support is available on Linux.

 Wolfram Cloud  account is required in order to utilize the cloud-based features of WolframScript. 
          

  Using WolframScript on different platforms requires different escaping semantics. 

              WolframScript is distributed with Version  of the Wolfram Language and above.
