1. PyOhio 2019 Find Your Feature Fit How to pick a text editor for Python programming Gregory M. Kapfhammer Madelyn M. Kapfhammer
2. @GregKapfhammer www.gregorykapfhammer.com Hi! Glad to be Back at PyOhio! GREGORY M. KAPFHAMMER
3. @MaddyKapfhammer www.madelynkapfhammer.com Hello! It's Great to Meet You! MADELYN M. KAPFHAMMER
4. Developer Productivity Programming Fun Effective Code Why Care About a Text Editor?
5. VS CODE VIM
6. A FAST PACED FIELD
7. Showcase noteworthy features Compare and contrast text editors Highlight less available information Share the thrill of customization Key Goals
8. Ease of ... Installation Use Customization Evaluation Metrics
9. Learn Key Editor Features Learn the basics before you copy confusing con gurations
10. Install Useful Text Editor Plugins Discover new plugins and update them on a regular basis
11. Visual Studio Code Open Command Palette: Ctrl+Shift+P IntelliSense: Uses Language Server Protocol Save con guration in the User Settings Remember to download the Python Extension The Basics
12. Enable Black Code Formatting
13. Enable Tab Completion
14. Enable Flake8 Code Linting
15. Vim or Neovim Vim or Neovim in a terminal with tmux Con gure editor through .vimrc or init.vim Install plugins with a plugin manager Add con guration options for plugins The Basics
16. Overview of Vim's Con guration File
17. Useful in both VS Code and Vim pyenv: Download and manage Python versions pipenv: Application deps and virtualenvs pytest: Run test cases and report their status coverage: Track statements and branches Development Tools
18. Con guration and Plugins BOTH SUPPORT PROJECTS AND OFFER MANY PLUGINS, BUT VS CODE IS EASIER TO CONFIGURE
19. Open-source tool to check the work of writers and programmers On GitHub at GatorEducator/gatorgrader pipenv shell: Enter a virtual environment pipenv run test: Run the test suite pipenv run cover: Check for full coverage GatorGrader
20. Install the Application Dependencies
21. Install Application Dependencies
22. Start Your Virtual Environment
23. Selecting a Virtual Environment
24. Start Project in a Virtual Environment
25. Virtual Environments and Package Installation BOTH EFFECTIVELY USE PIPENV TO MANAGE VIRTUALENVS AND APP DEPENDENCIES
26. Let's Start Programming in Python!
27. Calculate Test Suite Coverage Work on an existing code base
28. Terminal command: pipenv run cover
29. 99% total coverage 98% coverage test_util.py
30. I thought coverage was 100%? "It is 100%! Wait, what?"
31. Fuzzy File Finding for the Test
32. What's the Problem?
33. Hardcoded Test Variable
34. Let's Fix the Test! Use Pytest's tmpdir test xture
35. Use Pytest's tmpdir xture
36. Wait, this x is still incomplete!
37. View and Act on Flake8 Warning
38. Automated Code Linting BOTH ALLOW MULTIPLE BACKGROUND LINTERS, WITH CUSTOMIZATION DIFFERENCES
39. Code Autocompletion BOTH EDITORS OFFER SUPPORT, WITH TRADE-OFFS IN RELEVANCE AND PERFORMANCE
40. Source Code Formatting
41. Code Formatting BOTH EDITORS CAN LEVERAGE BLACK, BUT VS CODE IS MUCH EASIER TO CONFIGURE
42. Run Test Suites Did we x the hard-coded test?
43. Python Test Explorer
44. Convert tmpdir to a String
45. Run Tests and Coverage
46. Check Test Suite Coverage
47. 100% total coverage!
48. Automated Testing BOTH SUPPORT TESTING WELL, BUT OFFER A VERY DIFFERENT USER EXPERIENCE
49. Source Code Highlighting BOTH SUPPORT FAST SYNTAX HIGHLIGHTING, BUT VIM REQUIRES AN EXTRA PLUGIN
50. Text Snippets Save time by using a template for text Autocompletion trigger inserts text
51. Snippet Expansion BOTH EDITORS SUPPORT SNIPPETS, BUT VIM WORKS WELL IN MORE SCENARIOS
52. Try multiple editors! Which one did you like best? Why?
53. VS CODE VIM
54. VS CODE VIM
55. Editing Documentation in Markdown Integration with Git and GitHub Automated source code refactoring Adding and removing dependencies Releasing a Python application to PyPI Learning Opportunities
