Without getting too much into it, Nix is a cross-platform package manager that utilizes a purely functional deployment model where software is installed into unique directories generated through cryptographic hashes. To achieve this, we’re going to use the Nix Package Manager. Creating a Python 3.6 virtual environment Let’s focus on getting our Python 3.6 environment working on the new MacBook. I have a fun fact about Rosetta at the end of the article for you. Check the box that says ‘Open using Rosetta’ and close. Go to Finder > Applications > Utilities > Right click the terminal app and select ‘Get Info’. It would be wise to mention that you can run your entire Terminal under Rosetta, although I’m not sure if it’s advisable to do so.

You can install the Rosetta environment by running the following command: softwareupdate -install-rosetta More about the Rosetta Translation Environment here. However, the translation process takes time, so users might perceive that translated apps launch or run more slowly at times. When translation finishes, the system launches the translated executable in place of the original. If an executable contains only Intel instructions, macOS automatically launches Rosetta and begins the translation process. So, what does Rosetta do exactly? According to Apple, It is not a substitute for creating a native version of your app. Rosetta is meant to ease the transition to Apple silicon, giving you time to create a universal binary for your app. Here’s what Apple has to say about Rosetta: Yay! So my old apps & any future apps that I may build will work the new chips anyway? Hold your horses, mate. In simple words, it translates apps built for Intel so they will run on Apple Silicon. Rosetta 2 is an emulator designed to bridge the transition between Intel and Apple processors. Does that mean my new MacBook is no good? Python 3.9.1 becomes the first version of the language to support macOS 11 Big Sur, and in turn supporting the M1-powered MacBooks.īut wait, Python 3.9.1 is fairly new, and my app may break if I upgrade. You can now run Python on the Apple MacBook with M1 Chip The processor can no longer understand the x86_64 instructions and hence, some of your programs may not work with the M1.Īlthough it is important to note that more and more apps are being made compatible with the new M1 chips on the block. This means all the apps or software you may be used to were written using instructions written for these Intel or AMD (x86_64) processors.īut with the M1 chip, things changed. Till now, you may have used Intel-based Macs or laptops which are based on the x86_64 architecture.

Also, the chip will allow iPhone and iPad apps to run on the Mac for the first time. M1 also claims better power efficiency with higher performance during usage. This allows faster performance on Mac computers using M1 versus separate CPU, GPU, RAM, and other components. The M1 is an 8-core, 5 nanometer processor with unified memory architecture. The Apple Silicon M1 Chip is the company’s first System-on-Chip (SoC) and the first in the family of Apple Silicon chips based on ARM. What is the new M1 Chip & what makes it different? One of my projects uses Python 3.6 & since it a deployed project, changing the Python version just so that it is compatible with my swanky new companion would be a recipe for disaster 💥!īefore we get to the workaround of this, let’s understand the new M1 chip in a bit more detail.

I got an Apple MacBook Pro with the new M1 chip yesterday, and I immediately ran into a problem setting it up for my development projects. This article won’t dive into the comparison between different options out there, but if you bought the new Apple MacBook with the M1 chip, you might want to read through. They have offered consistent performance & efficiency over the last couple of years making them the preferred choice for developers (although they’re a bit 💰 expensive 💰 than other choices out there).

С For Mac Programming

In this tutorial, you use Python 3 to create the simplest Python 'Hello World' application in Visual Studio Code. By using the Python extension, you make VS Code into a great lightweight Python IDE (which you may find a productive alternative to PyCharm).

Mac Programming Software

Cocoa Programming

This tutorial introduces you to VS Code as a Python environment, primarily how to edit, run, and debug code through the following tasks:

Write, run, and debug a Python 'Hello World' Application

Learn how to install packages by creating Python virtual environments

Write a simple Python script to plot figures within VS Code

This tutorial is not intended to teach you Python itself. Once you are familiar with the basics of VS Code, you can then follow any of the programming tutorials on python.org within the context of VS Code for an introduction to the language.

If you have any problems, feel free to file an issue for this tutorial in the VS Code documentation repository.

Note: You can use VS Code with Python 2 with this tutorial, but you need to make appropriate changes to the code, which are not covered here.

Prerequisites

Written by members of the development team at Apple, Programming with Quartz is the first book to describe the sophisticated graphics system of Mac OS X. By using the methods described in this book, developers will be able to fully exploit the state-of-the-art graphics capabilities of Mac OS X in their applications, whether for Cocoa or Carbon development. Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Nov 29, 2016 Download Dev-C for free. A free, portable, fast and simple C/C IDE. A new and improved fork of Bloodshed Dev-C.

To successfully complete this tutorial, you need to first setup your Python development environment. Specifically, this tutorial requires:

VS Code

VS Code Python extension

Python 3

Install Visual Studio Code and the Python Extension

If you have not already done so, install VS Code.

Next, install the Python extension for VS Code from the Visual Studio Marketplace. For additional details on installing extensions, see Extension Marketplace. The Python extension is named Python and it's published by Microsoft.

Install a Python interpreter

Along with the Python extension, you need to install a Python interpreter. Which interpreter you use is dependent on your specific needs, but some guidance is provided below.

Windows

Install Python from python.org. You can typically use the Download Python button that appears first on the page to download the latest version.

Note: If you don't have admin access, an additional option for installing Python on Windows is to use the Microsoft Store. The Microsoft Store provides installs of Python 3.7 and Python 3.8. Be aware that you might have compatibility issues with some packages using this method.

For additional information about using Python on Windows, see Using Python on Windows at Python.org

macOS

The system install of Python on macOS is not supported. Instead, an installation through Homebrew is recommended. To install Python using Homebrew on macOS use brew install python3 at the Terminal prompt.

Note On macOS, make sure the location of your VS Code installation is included in your PATH environment variable. See these setup instructions for more information.

Linux

The built-in Python 3 installation on Linux works well, but to install other Python packages you must install pip with get-pip.py.

Other options

Data Science: If your primary purpose for using Python is Data Science, then you might consider a download from Anaconda. Anaconda provides not just a Python interpreter, but many useful libraries and tools for data science.

Windows Subsystem for Linux: If you are working on Windows and want a Linux environment for working with Python, the Windows Subsystem for Linux (WSL) is an option for you. If you choose this option, you'll also want to install the Remote - WSL extension. For more information about using WSL with VS Code, see VS Code Remote Development or try the Working in WSL tutorial, which will walk you through setting up WSL, installing Python, and creating a Hello World application running in WSL.

Verify the Python installation

To verify that you've installed Python successfully on your machine, run one of the following commands (depending on your operating system):

Linux/macOS: open a Terminal Window and type the following command:

Windows: open a command prompt and run the following command:

If the installation was successful, the output window should show the version of Python that you installed.

Note You can use the py -0 command in the VS Code integrated terminal to view the versions of python installed on your machine. The default interpreter is identified by an asterisk (*).

Start VS Code in a project (workspace) folder

Using a command prompt or terminal, create an empty folder called 'hello', navigate into it, and open VS Code (code) in that folder (.) by entering the following commands:

Note: If you're using an Anaconda distribution, be sure to use an Anaconda command prompt.

By starting VS Code in a folder, that folder becomes your 'workspace'. VS Code stores settings that are specific to that workspace in .vscode/settings.json, which are separate from user settings that are stored globally.

Alternately, you can run VS Code through the operating system UI, then use File > Open Folder to open the project folder.

Select a Python interpreter

Python is an interpreted language, and in order to run Python code and get Python IntelliSense, you must tell VS Code which interpreter to use.

From within VS Code, select a Python 3 interpreter by opening the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), start typing the Python: Select Interpreter command to search, then select the command. You can also use the Select Python Environment option on the Status Bar if available (it may already show a selected interpreter, too):

The command presents a list of available interpreters that VS Code can find automatically, including virtual environments. If you don't see the desired interpreter, see Configuring Python environments.

Note: When using an Anaconda distribution, the correct interpreter should have the suffix ('base':conda), for example Python 3.7.3 64-bit ('base':conda).

Selecting an interpreter sets the python.pythonPath value in your workspace settings to the path of the interpreter. To see the setting, select File > Preferences > Settings (Code > Preferences > Settings on macOS), then select the Workspace Settings tab.

Note: If you select an interpreter without a workspace folder open, VS Code sets python.pythonPath in your user settings instead, which sets the default interpreter for VS Code in general. The user setting makes sure you always have a default interpreter for Python projects. The workspace settings lets you override the user setting.

Create a Python Hello World source code file

From the File Explorer toolbar, select the New File button on the hello folder:

Name the file hello.py, and it automatically opens in the editor:

By using the .py file extension, you tell VS Code to interpret this file as a Python program, so that it evaluates the contents with the Python extension and the selected interpreter.

Note: The File Explorer toolbar also allows you to create folders within your workspace to better organize your code. You can use the New folder button to quickly create a folder.

Now that you have a code file in your Workspace, enter the following source code in hello.py:

When you start typing print, notice how IntelliSense presents auto-completion options.

IntelliSense and auto-completions work for standard Python modules as well as other packages you've installed into the environment of the selected Python interpreter. It also provides completions for methods available on object types. For example, because the msg variable contains a string, IntelliSense provides string methods when you type msg.:

Feel free to experiment with IntelliSense some more, but then revert your changes so you have only the msg variable and the print call, and save the file (⌘S (Windows, Linux Ctrl+S)).

Mac Programming Software

For full details on editing, formatting, and refactoring, see Editing code. The Python extension also has full support for Linting.

Run Hello World

It's simple to run hello.py with Python. Just click the Run Python File in Terminal play button in the top-right side of the editor.

The button opens a terminal panel in which your Python interpreter is automatically activated, then runs python3 hello.py (macOS/Linux) or python hello.py (Windows):

There are three other ways you can run Python code within VS Code:

Right-click anywhere in the editor window and select Run Python File in Terminal (which saves the file automatically):

Select one or more lines, then press Shift+Enter or right-click and select Run Selection/Line in Python Terminal. This command is convenient for testing just a part of a file.

From the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)), select the Python: Start REPL command to open a REPL terminal for the currently selected Python interpreter. In the REPL, you can then enter and run lines of code one at a time.

Configure and run the debugger

Let's now try debugging our simple Hello World program.

First, set a breakpoint on line 2 of hello.py by placing the cursor on the print call and pressing F9. Alternately, just click in the editor's left gutter, next to the line numbers. When you set a breakpoint, a red circle appears in the gutter.

Next, to initialize the debugger, press F5. Since this is your first time debugging this file, a configuration menu will open from the Command Palette allowing you to select the type of debug configuration you would like for the opened file.

Note: VS Code uses JSON files for all of its various configurations; launch.json is the standard name for a file containing debugging configurations.

These different configurations are fully explained in Debugging configurations; for now, just select Python File, which is the configuration that runs the current file shown in the editor using the currently selected Python interpreter.

The debugger will stop at the first line of the file breakpoint. The current line is indicated with a yellow arrow in the left margin. If you examine the Local variables window at this point, you will see now defined msg variable appears in the Local pane.

A debug toolbar appears along the top with the following commands from left to right: continue (F5), step over (F10), step into (F11), step out (⇧F11 (Windows, Linux Shift+F11)), restart (⇧⌘F5 (Windows, Linux Ctrl+Shift+F5)), and stop (⇧F5 (Windows, Linux Shift+F5)).

The Status Bar also changes color (orange in many themes) to indicate that you're in debug mode. The Python Debug Console also appears automatically in the lower right panel to show the commands being run, along with the program output.

To continue running the program, select the continue command on the debug toolbar (F5). The debugger runs the program to the end.

Tip Debugging information can also be seen by hovering over code, such as variables. In the case of msg, hovering over the variable will display the string Hello world in a box above the variable.

You can also work with variables in the Debug Console (If you don't see it, select Debug Console in the lower right area of VS Code, or select it from the ... menu.) Then try entering the following lines, one by one, at the > prompt at the bottom of the console:

Select the blue Continue button on the toolbar again (or press F5) to run the program to completion. 'Hello World' appears in the Python Debug Console if you switch back to it, and VS Code exits debugging mode once the program is complete.

If you restart the debugger, the debugger again stops on the first breakpoint.

To stop running a program before it's complete, use the red square stop button on the debug toolbar (⇧F5 (Windows, Linux Shift+F5)), or use the Run > Stop debugging menu command.

For full details, see Debugging configurations, which includes notes on how to use a specific Python interpreter for debugging.

Tip: Use Logpoints instead of print statements: Developers often litter source code with print statements to quickly inspect variables without necessarily stepping through each line of code in a debugger. In VS Code, you can instead use Logpoints. A Logpoint is like a breakpoint except that it logs a message to the console and doesn't stop the program. For more information, see Logpoints in the main VS Code debugging article.

Install and use packages

Let's now run an example that's a little more interesting. In Python, packages are how you obtain any number of useful code libraries, typically from PyPI. For this example, you use the matplotlib and numpy packages to create a graphical plot as is commonly done with data science. (Note that matplotlib cannot show graphs when running in the Windows Subsystem for Linux as it lacks the necessary UI support.)

Return to the Explorer view (the top-most icon on the left side, which shows files), create a new file called standardplot.py, and paste in the following source code:

Cocoa Programming

Tip: If you enter the above code by hand, you may find that auto-completions change the names after the as keywords when you press Enter at the end of a line. To avoid this, type a space, then Enter.

Next, try running the file in the debugger using the 'Python: Current file' configuration as described in the last section.

Unless you're using an Anaconda distribution or have previously installed the matplotlib package, you should see the message, 'ModuleNotFoundError: No module named 'matplotlib'. Such a message indicates that the required package isn't available in your system.

To install the matplotlib package (which also installs numpy as a dependency), stop the debugger and use the Command Palette to run Terminal: Create New Integrated Terminal (⌃⇧` (Windows, Linux Ctrl+Shift+`)). This command opens a command prompt for your selected interpreter.

A best practice among Python developers is to avoid installing packages into a global interpreter environment. You instead use a project-specific virtual environment that contains a copy of a global interpreter. Once you activate that environment, any packages you then install are isolated from other environments. Such isolation reduces many complications that can arise from conflicting package versions. To create a virtual environment and install the required packages, enter the following commands as appropriate for your operating system:

Note: For additional information about virtual environments, see Environments.

Create and activate the virtual environment

Note: When you create a new virtual environment, you should be prompted by VS Code to set it as the default for your workspace folder. If selected, the environment will automatically be activated when you open a new terminal.

For windows

If the activate command generates the message 'Activate.ps1 is not digitally signed. You cannot run this script on the current system.', then you need to temporarily change the PowerShell execution policy to allow scripts to run (see About Execution Policies in the PowerShell documentation):

For macOS/Linux

Select your new environment by using the Python: Select Interpreter command from the Command Palette.

Install the packages

Rerun the program now (with or without the debugger) and after a few moments a plot window appears with the output:

Once you are finished, type deactivate in the terminal window to deactivate the virtual environment.

For additional examples of creating and activating a virtual environment and installing packages, see the Django tutorial and the Flask tutorial.

Next steps

You can configure VS Code to use any Python environment you have installed, including virtual and conda environments. You can also use a separate environment for debugging. For full details, see Environments.

Введение

Уже долгое время не пишу статьи о разработке, хотя сам процесс написания мне очень нравится и позволяет привести мысли в порядок. И все от того, что все это время был занят разработкой довольно интересного проекта.

Но вот, есть возможность сейчас рассказать о наработках, которые появились за последнее время. Надеюсь, кому-то этот текст сильно упростит жизнь и даст толчок к покорению новых вершин.

В этот раз речь пойдет о создании кроссплатформенных приложений с плагинами на C++ с использованием библиотеки wxWidgets. Рассматриваться будут операционные системы Windows, Linux и OS X, как наиболее популярные.

Как обычно, первая часть будет обзорной, для того, чтобы снизить порог входа для читателей. Кому-то информация из первой части покажется очевидной (особенно то, что касается инструментария), но, все же, я считаю ее необходимой, ибо для новичков информация из первой части позволит с минимальными усилиями организовать процесс разработки.
