![]() If the ENV_PATH is properly set, we can use python3 /path/to/file.py Keyboard Maestro will search through these directories and look for python3. We do this by creating a Keyboard Maestro variable called ENV_PATH. We have to let Keyboard Maestro know where the python3 interpreter is. ![]() When we run python scripts in Keyboard Maestro, we are not in the Terminal anymore. We will have to add the path to python3 to it by editing a file named. Otherwise, it will say that the interpreter is lacking. Therefore, the order of the directories matters). (if you have multiple python3 interpreters, the first that is found will be used as the interpreter. ![]() zsh search search these directories, looking for python3, if it finds it, then it will ask python3 to run the script. If we run echo $PATH in the terminal, we will get a serial of directories separated by. If python3 is installed but zsh does not know it, then you will have to know where does zsh searches for python3. When we run which python3, if python3 is installed and zsh knows where it is, the which python3 command will return the path to python3, something like /usr/local/bin/python3. On the mac, if the default language is zsh, zsh has to know where python3 (called interpreter) is and asks it to execute the scripts. When we use a command in the terminal, say python3 /path/to/file.py. I'll try to describe how I understand it. ![]() It took me a long time to understand the environ path. I knew nothing about environ path when I started to learn programming languages. set strJoined to lstText as text set my text item delimiters to dlm If an undeclared variable name is detected when the 'use strict' statement has been added, we are given a helpful warning: When we do this, JavaScript checks that all of our variables are declared (and therefore 'local' – visible only to their containing functions, and also temporary – vanishing when the evaluation of a function is completed). To use a less liberal but more helpful set of JavaScript rules, we can add the line 'use strict' Īt the start of a function. Misspelled variable names, and accidental uses of the same globally visible name in different parts of a script are rich sources of puzzling bugs and wasted time. JavaScript gives us a lot of freedom, sometimes more than is helpful. Messy and complex JXA – persistent global names Good and simple JXA – temporary local names Keyboard Maestro’s Execute a JavaScript in Safari and Execute a JavaScript in Google Chrome actions are for interacting with web pages, the Execute a JavaScript in Custom Prompt action is for interacting with Custom HTML Prompts, whereas JXA is for automating OS X and OS X Applications via the Execute a JavaScript For Automation action. Later on, you may find it interesting to scan this output list for useful functions, but for the moment, it's enough to simply notice that the JXA JavaScript environment is very different from the set of web page (window and document) references that you find in the Browser JavaScript environments of Chrome and Safari. We can either run this directly from from one of Keyboard Maestro's 'Execute a JavaScript for Automation' actions, or use an osascript command in an Execute Shell Script action. The result will be a listing of all the pre-defined names in JXA's osascript environment. You can view the built-in, default function provided by JXA by running this simple, one-word script: With additional access to a lot of low-level Apple system functions through the Objective-C object.
