Prettier-Standard - JavaScript formatter

Formats entire JavaScript/TypeScript documents by applying Prettier's opinionated formatting rules combined with Standard linting conventions through the prettier-standard npm package. The extension hooks into VS Code's native formatting pipeline, detecting the project root to load .prettierrc configuration files, then applies deterministic AST-based transformations to normalize code style across indentation, spacing, semicolons, and quote preferences without requiring manual configuration of conflicting rules.

Formats only the selected text range within a document by parsing the selection boundaries, applying prettier-standard rules to just that code segment, and preserving the rest of the document unchanged. This works by extracting the selection from the editor state, running the formatter on that substring with appropriate context preservation (indentation level, scope awareness), and replacing only the selected range with formatted output.

Automatically triggers code formatting when a file is saved by hooking into VS Code's native `editor.formatOnSave` setting. The extension registers itself as a document formatter provider, intercepting save events and running prettier-standard formatting before the file is persisted to disk. This integration respects VS Code's editor configuration and can be toggled per-workspace or globally without requiring extension-specific settings.

Automatically detects and loads `.prettierrc` configuration files from the project root by traversing the directory tree from the current file's location upward until a `.prettierrc` file is found. This allows teams to define formatting rules once at the project level, and the extension applies those rules consistently across all files without requiring per-file or per-workspace configuration. The discovery respects VS Code's workspace root detection and handles monorepo structures by finding the nearest `.prettierrc` in the hierarchy.

Extends formatting capabilities beyond JavaScript to support TypeScript, JSX, TSX, JSON, CSS, SCSS, Less, GraphQL, Markdown, YAML, HTML, Vue, and other languages through Prettier's language plugin system. The extension detects the file type based on VS Code's language mode and routes the file to the appropriate Prettier parser, allowing developers to format heterogeneous codebases with a single tool. Configuration via .prettierrc applies language-specific rules (e.g., different indentation for YAML vs JavaScript).

Exposes formatting operations through VS Code's Command Palette (accessible via Cmd+Shift+P on macOS or Ctrl+Shift+P on Windows/Linux) with commands like 'Format Document' and 'Format Selection'. This allows developers to trigger formatting on-demand without using keyboard shortcuts, making the feature discoverable and accessible to users who prefer menu-driven workflows. The command palette integration respects the current editor state and applies formatting to the active document or selection.

Provides keyboard shortcut access to formatting via the default VS Code format binding (Shift+Alt+F on Windows/Linux, Shift+Cmd+F on macOS). This allows developers to format code with a single keystroke without opening the command palette or using menu navigation. The shortcut respects the current editor state and applies formatting to the active document or selection based on whether text is selected.
