        "content": "When you see the message in VS Code saying *\u201cDo you want to install the recommended \u2018Ruff\u2019 extension\u2026 for this repository?\u201d*, it\u2019s VS Code\u2019s way of suggesting a linter tool that seems like a good fit for your project. Microsoft has built VS Code to recommend extensions based on your workspace contents\u2014e.g. if it detects Python files and sees settings or project configurations that point toward Ruff, it\u2019ll bring up that recommendation.\n\nHere's a breakdown of why VS Code might be recommending Ruff, what makes it distinct vs something like Pylint or other Microsoft-associated or conventional Python linters, and when one might be better than another.\n\n---\n\n## What is Ruff?\n\n- Ruff is an extremely fast Python linter and formatter written in Rust. ([docs.astral.sh](https://docs.astral.sh/ruff/linter/?utm_source=openai))  \n- It aims to be an *all-in-one* replacement for several tools: Flake8 (plus many of its plugins), isort (import sorting), Black (formatting), pyupgrade (syntax modernization), pydocstyle (docstrings), and autoflake (removing unused imports) among others. ([docs.astral.sh](https://docs.astral.sh/ruff/linter/?utm_source=openai))  \n- It supports automatic fixes for many violations. ([docs.astral.sh](https://docs.astral.sh/ruff/linter/?utm_source=openai))  \n- Ruff is often 10-100\u00d7 faster than those traditional tools. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai))  \n\nSo Ruff trades breadth, speed, and consolidation for certain specialized or deep analysis features.\n\n---\n\n## Why VS Code Is Recommending Ruff\n\nThere are a few reasons for that suggestion:\n\n1. **Speed and feedback loop**: Because Ruff is fast, you can get linting feedback quickly while coding, not just in CI. That improves developer experience. Data shows VS Code often detects these newer tools in repos and recommends them if it sees relevant config files or dependencies.  \n\n2. **Popularity and adoption**: Ruff has been gaining traction. It's considered by many as a modern replacement for common linters or tools in Python workflows. Many projects are migrating to it. ([astral.sh](https://astral.sh/ruff?utm_source=openai))  \n\n3. **Built-in support/options in VS Code**: There's an official Ruff extension (\u201cruff-vscode\u201d) that provides editor integration: linting, formatting, import organizing, quick fixes, etc. ([github.com](https://github.com/astral-sh/ruff-vscode?utm_source=openai))  \n\n4. **Maintenance convenience**: Replacing several tools with one reduces setup complexity, conflicts, multiple config files, plugin issues, slower tools, etc. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai))  \n\n---\n\n## How Ruff Compares to Pylint and Other Conventional/\u201cMicrosoft-associated\u201d Linters\n\nHere\u2019s a comparison among Ruff, Pylint, and other tools often used in VS Code (like Flake8, Black, Pyright, etc.):\n\n| Tool / Feature | Ruff | Pylint | Others (like Flake8, Black, Pyright) |\n|----------------|------|--------|----------------------------------------|\n| **Speed** | Very high. Ruff runs in Rust, optimized, parallel, etc. ([astral.sh](https://astral.sh/ruff?utm_source=openai)) | Slower\u2014Pylint is thorough and written in Python; can lag behind on large codebases. |\n| **Scope of checks** | Broad: includes style, formatting & auto-fixable issues; many Flake8 plugin rules; import sorting; etc. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai)) | Very thorough, especially on code style + potential runtime bugs, design issues; more semantic checks. |\n| **Configurability** | Good. Uses `pyproject.toml` / `ruff.toml`, allows selecting or ignoring rule categories. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai)) | Highly configurable; many options; more granular control (but with more complexity). |\n| **Auto-fix / formatting** | Strong support; can apply fixes automatically; includes formatting and isort-style import ordering. ([docs.astral.sh](https://docs.astral.sh/ruff/linter/?utm_source=openai)) | Pylint has *some* auto-fix capability (e.g. via plugins or external tools) but less focused on formatting; doesn't replace Black or isort. |\n| **Depth / semantic analysis** | Less deep on some semantic issues (type checking, complex interdependencies). Meant more for static style, bug patterns, formatting. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai)) | Very strong; finds logical design issues, certain runtime issues, more reports. |\n| **Ecosystem & maturity** | Newer, but rapidly maturing. Widely adopted. ([astral.sh](https://astral.sh/ruff?utm_source=openai)) | Long\u2010established; many integrations and plugins; widely trusted. |\n\n\u201cMicrosoft\u2019s conventional linter\u201d for Python is often a mix: the official VS Code Python extension enables linting via Pylint, Flake8 etc.; Microsoft also provides Pylance (for semantic analysis / typing) and Pyright. Formatting is often done via Black, isort, etc. So these are \u201cstandard tools\u201d many teams already use.\n\n---\n\n## Is Ruff Preferable?\n\nIt depends on your priorities and project constraints. Here are some situations where Ruff might be preferable, and some where you might still want Pylint or another tool.\n\n**Choose Ruff if:**\n\n- You want **fast feedback** while coding (on save, continuously). Ruff is order-of-magnitude faster.  \n- You want to simplify your tooling stack: fewer separate tools to configure and maintain.  \n- Your project cares more about style, formatting, linting, import ordering, code modernization, etc., than deep design/architectural analysis.  \n- You want auto-fix fixes and formatting built in with one tool.  \n\n**Stick with Pylint (or use both) if:**\n\n- You need **more in-depth analysis** of code semantics, complex dependencies, design issues, etc. Pylint has rules Ruff may not yet cover or may cover only partially. ([pydevtools.com](https://pydevtools.com/handbook/explanation/ruff-complete-guide/?utm_source=openai))  \n- You or your team is already heavily invested in existing workflows and plugins around Pylint, or your CI path depends on specific Pylint rules.  \n- You want long-established stability and confidence, especially when linting large/legacy codebases where rule behavior matters deeply.  \n\nOften, using **both** is reasonable: use Ruff for everyday feedback & style/format checks, and have Pylint (and maybe type checkers like MyPy or Pyright) run in CI to catch deeper problems.\n\n---\n\n## Advice: What to Do in Your Case\n\nGiven the prompt you're seeing in VS Code\u2014this suggests that VS Code detected something in your repository that makes Ruff look useful/relevant (e.g., a config file, or a dependency). You can decide based on priorities:\n\n- If you're curious, **try installing the Ruff extension**. See how its suggestions and formatting feel in your normal edit workflow. If it speeds things up and the linting style matches what you want, it might improve productivity.\n\n- If you already use Pylint or have strict requirements on what your linter must catch, test Ruff on your codebase; check if Ruff misses important errors Pylint catches. If so, you might keep Pylint for those and let Ruff handle style/format.\n\n- Also check how your CI is set up. If CI expects Pylint results, changing might require updates elsewhere.\n\n---\n\nIf you want help comparing them *on your exact repo*\u2014e.g. see what rules Ruff would flag vs Pylint for your code\u2014I can help you try that out. Do you want a side-by-side comparison for your project?"

Below are common settings and extensions to disable, plus how to do it via settings. \n\n---\n\n## What to Disable / Tweak\n\nHere are the Microsoft Python extension tools or features that often conflict with Ruff, and how you can disable or limit them:\n\n| Tool / Feature | Why It Conflicts with Ruff | How to Disable or Limit |\n|---|------------------------------|---------------------------|\n| **Pylint** | Ruff already covers many lint rules; Pylint may report overlapping or similar issues, causing noise. | Set `python.linting.pylintEnabled` to `false` in your workspace settings. Disabling the Pylint VS Code extension also works. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=ms-python.pylint&utm_source=openai)) |\n| **Flake8** | Ruff includes support for many Flake8 rules and plugins; having both running is redundant. | If you use `python.linting.flake8Enabled`, disable it. Remove any Flake8\u2010specific extensions/config. |\n| **isort** (import sorter) | Ruff can sort imports (`organizeImports`) similar to isort; duplication if both are active. | In the Ruff extension settings, set `\"ruff.organizeImports\": false` if you want to keep isort. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai)) |\n| **Black or other formatters** | Ruff includes its own formatter; having Black and Ruff both formatting may cause conflicts. | Remove/disable the other formatter or ensure only one formatter is set as default (`\"editor.defaultFormatter\"` setting) or set it to `null`. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai)) |\n| **Automatic code actions on save** (e.g. organizing imports, format on save) | Ruff provides these; redundant save\u2010time actions could overlap. | Use the VS Code settings for `\"[python]\": { \"editor.codeActionsOnSave\": { ... }}` to target Ruff specifically. E.g., `\"source.organizeImports.ruff\": \"explicit\"` etc. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai)) |\n\n---\n\n## How to Disable Tools / Settings in VS Code\n\nHere are concrete ways to disable or adjust so that Ruff is the primary linter/formatter:\n\n1. **Disable Pylint**\n\n   In your `.vscode/settings.json` (workspace settings), add:\n\n   ```json\n   {\n     \"python.linting.pylintEnabled\": false,\n     \"python.linting.enabled\": true  // ensure linting is on if you want Ruff\n   }\n   ```\n\n   Or disable the Pylint extension via the Extensions pane, either for the workspace or globally. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=ms-python.pylint&utm_source=openai))\n\n2. **Disable Flake8**\n\n   ```json\n   {\n     \"python.linting.flake8Enabled\": false\n   }\n   ```\n   \n   If you have Flake8 extension(s) installed, disable them similarly.  \n\n3. **Disable or tweak formatter settings**\n\n   If you previously used Black (or autopep8 etc.), you\u2019ll want to either disable that extension or set Ruff as the default:\n\n   ```json\n   {\n     \"[python]\": {\n       \"editor.defaultFormatter\": \"charliermarsh.ruff\"\n     }\n   }\n   ```\n\n4. **Organize Imports / Import sorting**\n\n   If you want Ruff to handle import sorting, disable other import organizer tools (like isort extension or built-in actions):\n\n   ```json\n   {\n     \"ruff.organizeImports\": false  // if you want to keep isort instead\n   }\n   ```\n   \n   Or if using Ruff for both linting and import sorting:\n\n   ```json\n   {\n     \"[python]\": {\n       \"editor.codeActionsOnSave\": {\n         \"source.fixAll.ruff\": \"explicit\",\n         \"source.organizeImports.ruff\": \"explicit\"\n       }\n     }\n   }\n   ```\n\n5. **Disable redundant code actions / fixes by non\u2010Ruff extensions**\n\n   Ensure that `codeActionsOnSave` doesn't include other organizers or formatters overlapping with Ruff. Only include the Ruff ones where needed.\n\n---\n\n## Example `settings.json`\n\nHere\u2019s an example that configures a workspace to use Ruff and disables Pylint, Flake8, etc.:\n\n```json\n{\n  \"python.linting.enabled\": true,\n  \"python.linting.pylintEnabled\": false,\n  \"python.linting.flake8Enabled\": false,\n  \"python.formatting.provider\": \"none\",\n  \"[python]\": {\n    \"editor.defaultFormatter\": \"charliermarsh.ruff\",\n    \"editor.formatOnSave\": true,\n    \"editor.codeActionsOnSave\": {\n      \"source.fixAll.ruff\": \"explicit\",\n      \"source.organizeImports.ruff\": \"explicit\"\n    }\n  },\n  \"ruff.organizeImports\": true // or false if you prefer a separate import tool\n}\n```\n\n---\n\nIf you tell me which exact tools you currently have enabled (Pylint, Flake8, Black, isort, etc.), I can suggest a tailored set of settings for your project."

Whether it\u2019s the best place depends a bit on your setup, which I'll detail.\n\n---\n\n## How VS Code handles workspace & folder settings\n\n- If you open a `.code-workspace` file, that defines a **multi-root** (or project-wide) workspace. Any settings under its `\"settings\"` section are used as *workspace settings*. ([code.visualstudio.com](https://code.visualstudio.com/docs/editing/workspaces/workspaces?utm_source=openai))  \n- If you open a single folder (not via `.code-workspace`), then workspace settings go into `.vscode/settings.json` in that folder. ([code.visualstudio.com](https://code.visualstudio.com/docs/editing/workspaces/workspaces?utm_source=openai))  \n- In a multi-root workspace, each folder inside can also have its own `.vscode/settings.json` (called *folder settings*) which override workspace settings for that specific folder. ([stackoverflow.com](https://stackoverflow.com/questions/44629890/what-is-a-workspace-in-visual-studio-code?utm_source=openai))  \n\n---\n\n## Putting Ruff / linting settings into `.code-workspace`\n\nBecause you already have a `.code-workspace` file on the server, you *can* put all relevant settings there. Example:\n\n```json\n{\n  \"folders\": [\n    {\n      \"path\": \".\"\n    }\n  ],\n  \"settings\": {\n    \"python.linting.pylintEnabled\": false,\n    \"python.linting.flake8Enabled\": false,\n    \"[python]\": {\n      \"editor.defaultFormatter\": \"charliermarsh.ruff\",\n      \"editor.formatOnSave\": true,\n      \"editor.codeActionsOnSave\": {\n        \"source.fixAll.ruff\": \"explicit\",\n        \"source.organizeImports.ruff\": \"explicit\"\n      }\n    },\n    \"ruff.organizeImports\": true\n  }\n}\n```\n\nWhen this workspace file is opened in VS Code, these settings will be applied.   \n\n---\n\n## Pros & cons of using `.code-workspace` vs `.vscode/settings.json`\n\n| Advantage of `.code-workspace` | Disadvantages / things to watch out for |\n|-------------------------------|--------------------------------------------|\n| Centralised settings for all roots in the workspace. Easier to version control and share across team. | These settings only apply when opening via that `.code-workspace`. If someone opens just a folder (not via the workspace file), they may not get them. |\n| All the workspace settings are in one place. Good for CI or remote dev where you always open the workspace file. | Some config tools/plugins/extensions might expect settings under `.vscode/settings.json` and may not read workspace file\u2019s settings (rare). |\n| Supports folder-specific overrides via folder settings JSONs if needed. | Extra file to manage; potential duplication if both `.code-workspace` settings and `.vscode/settings.json` conflict. |\n\n---\n\n## Best practices for your context (server workspace)\n\nGiven you have a `.code-workspace` file *on the server*, and I assume you and your team connect to it (remote dev, SSH, etc.) using that workspace:\n\n- Yes, put the Ruff enable/disable settings and formatter/linter settings into the `\"settings\"` section of the `.code-workspace` file. That way everyone using that workspace gets the same lint/format setup.  \n- Make sure you also check and remove or disable overlapping settings in any `.vscode/settings.json` files if they exist, to avoid conflicts. VS Code should use the following precedence: **Folder settings** > **Workspace settings (from `.code-workspace`)** > **User settings**. ([vscode-docs.readthedocs.io](https://vscode-docs.readthedocs.io/en/stable/customization/userandworkspace/?utm_source=openai))  \n- Document that people should *open the project via** the `.code-workspace` file**, so the intended settings are applied. Otherwise, folder settings or defaults might prevail.\n\n---\n\nIf you want, I can help you write out the exact settings to put in your `.code-workspace` file (or merge with your existing `.vscode/settings.json`) based on the tools you\u2019re currently using. Want me to generate that for you?"

Don\u2019t disable the primary Microsoft Python extension\u2014just disable/turn off parts of its linting/formatting functionality that overlap with what Ruff does. Here\u2019s why and what to do instead.\n\n---\n\n## What ms-python.python (the MS Python extension) provides\n\nThe Microsoft Python extension (often referred to as `ms-python.python`) is almost essential for Python dev in VS Code. Key features it provides:\n\n- Interpreter selection, virtual environment support, code running/debugging.  \n- IntelliSense, code navigation, basic language semantics.  \n- Integration with other tools (including linters, formatters, test runners).  \n\nRuff depends on some of these capabilities. For example, the Ruff VS Code extension requires features from the MS Python extension to function correctly. The marketplace page says: *\u201cThis extension requires a version of the VSCode Python extension that supports Python 3.7+.\u201d* ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai))\n\n---\n\n## What parts of ms-python you *can* disable or adjust when using Ruff\n\nRuff overlaps with a number of linting/formatting features that might already be enabled via ms-python (or via related extensions).\n\nHere\u2019s what you should disable or tweak, while leaving ms-python enabled:\n\n| Feature from MS Python / related extensions | Reason to disable/tweak | Settings or actions |\n|----------------------------------------------|--------------------------|----------------------|\n| **Linting via Pylint, Flake8, etc.** | Avoid duplicate diagnostics/errors vs Ruff. | Use workspace settings: `python.linting.pylintEnabled = false`, `python.linting.flake8Enabled = false`. |\n| **Formatting (Black, autopep8, etc.)** | Ruff provides formatting (including import sorting and some Black-compatible style). | Remove or disable other formatters; set `editor.defaultFormatter` to the Ruff extension (id `charliermarsh.ruff`), and set `python.formatting.provider` to `\"none\"` or equivalent. |\n| **Import sorting via isort (or implicit in other tools)** | Ruff includes import organization. Overlapping tools can cause conflicts. | Disable the isort actions, or disable the `organizeImports` capability in other tools; use `source.organizeImports.ruff`. |\n| **Lint settings in Pylance / analysis** | Pylance can do some lint\u2010style checks which may duplicate Ruff results. | In VS Code settings, you can suppress conflicting Pylance diagnostics. For example, setting `\"python.analysis.ignore\": [\"*\"]` to turn off linting/analyses that overlap. ([bexli.dev](https://bexli.dev/posts/vscode/ruff-pylance/?utm_source=openai)) |\n\n---\n\n## Why you shouldn\u2019t disable ms-python.python entirely\n\nDisabling the MS Python extension would disable many core Python development features, including things Ruff doesn\u2019t replace:\n\n- Running tests/debugging.  \n- Code navigation, jump-to-definition, symbol indexing.  \n- Interpreter / venv selection.  \n- Language server functionality for non-lint things (e.g. type inference, type checking via Pylance or MyPy).  \n\nSo disabling ms-python.python would break more than just duplication\u2014it would remove essential IDE support. Ruff supplements, it doesn\u2019t replace all those features.\n\n---\n\n## Recommended configuration example\n\nHere\u2019s what a workspace (or `.code-workspace`) settings might look like when using Ruff alongside ms-python, with overlapping features disabled:\n\n```json\n{\n  \"python.linting.enabled\": true,\n  \"python.linting.pylintEnabled\": false,\n  \"python.linting.flake8Enabled\": false,\n  \"python.formatting.provider\": \"none\",\n  \"[python]\": {\n    \"editor.defaultFormatter\": \"charliermarsh.ruff\",\n    \"editor.formatOnSave\": true,\n    \"editor.codeActionsOnSave\": {\n      \"source.fixAll.ruff\": \"explicit\",\n      \"source.organizeImports.ruff\": \"explicit\"\n    }\n  },\n  \"ruff.organizeImports\": true,\n  \"ruff.lineLength\": 88,\n  \"python.analysis.ignore\": [\"*\"]  // to suppress overlapping diagnostics from Pylance\n}\n```\n\nYou\u2019d leave ms-python.python enabled, but ensure its overlapping features are turned off.\n\n---\n\nIf you want, I can help you generate *explicit settings* for your existing `.code-workspace` or `.vscode/settings.json` that are guaranteed to avoid overlap while keeping all essential functionality."

([ready-4-it.com](https://www.ready-4-it.com/de/blog/pylance-vs-ruff?utm_source=openai))  \n\n---\n\n## \u2694\ufe0f How Ruff and Pylance differ\n\n| Feature | Pylance | Ruff |\n|---------|---------|------|\n| Type checking / inference | \u2705 | \u274c \u2014 Ruff is a linter/formatter, not a type checker. ([docs.astral.sh](https://docs.astral.sh/ruff/faq/?utm_source=openai)) |\n| Auto-complete, go-to-definition | \u2705 | \u274c |\n| Formatting of code (style, Black-compatible) | \u274c | \u2705 ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai)) |\n| Linting for unused imports, code style, etc. | Some diagnostics, but not full linting stack | \u2705 covers what many tools like Flake8, isort, Black do ([astral.sh](https://astral.sh/ruff?utm_source=openai)) |\n\n---\n\n## \ud83d\udd0c Should you enable Pylance when using Ruff?\n\nYes \u2014 you should **keep Pylance enabled**, because Ruff does *not* replace Pylance\u2019s core functionality. Instead, you configure them to reduce overlapping diagnostics. Some settings help with that:\n\n- In `settings.json`, suppress Pylance\u2019s linting that Ruff will handle:\n\n```json\n\"python.analysis.ignore\": [\"*\"]\n```\n\nThis tells Pylance to ignore a broad set of diagnostics and avoid duplication. ([bexli.dev](https://bexli.dev/posts/vscode/ruff-pylance/?utm_source=openai))\n\n- Set Pylance as the language server (so you retain type checking, autocomplete, etc.) via:\n\n```json\n\"python.languageServer\": \"Pylance\"\n```\n\n- Meanwhile, configure Ruff to be your **formatter** and main **linter**, disabling competing tools like Flake8, Pylint, isort, etc. ([marketplace.visualstudio.com](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff&utm_source=openai))\n\n---\n\nIf you like, I can show you a recommended `.code-workspace` or `settings.json` block to get Ruff + Pylance working together *just right*."
