Renders diagnostic messages (errors, warnings, info, hints) directly at the end of lines in the editor using VS Code's inline decoration API, eliminating the need for hover interactions. Messages are positioned after code with configurable spacing (default 4ch margin) and styled with customizable font family, weight, size, and italic formatting. The extension consumes diagnostic data from VS Code's Language Server Protocol (LSP) and built-in diagnostic providers, then applies real-time decorations that update whenever diagnostics change.
Unique: Uses VS Code's native inline decoration API to render diagnostic messages at end-of-line with full styling control (font family, weight, size, italic, margin), rather than relying on hover tooltips or separate problem panels. Respects upstream VS Code diagnostic visibility settings via `respectUpstreamEnabled` configuration.
vs alternatives: More lightweight and integrated than separate diagnostic panels or hover-only approaches because it leverages VS Code's built-in decoration system and requires no external API calls or model inference.
Applies background color highlighting to entire lines containing diagnostics, with colors differentiated by severity level (error, warning, info, hint). The highlighting is rendered via VS Code's line decoration API and can be toggled independently from inline messages. Each severity level can be individually enabled or disabled through commands (`errorLens.toggleError`, `errorLens.toggleWarning`, etc.), allowing developers to filter visual noise by focusing on specific problem types.
Unique: Implements per-severity-level toggling via independent commands, allowing developers to selectively hide warnings while keeping errors visible, rather than an all-or-nothing diagnostic visibility toggle. Uses VS Code's line decoration API to apply background colors that respect theme color schemes.
vs alternatives: More granular than VS Code's built-in problem panel because it allows filtering by severity level without hiding diagnostics from the language server, and provides immediate visual feedback in context rather than requiring panel navigation.
Provides a command (`errorLens.searchForProblem`) that opens a browser search query for the current diagnostic, allowing developers to quickly search for documentation, solutions, or discussions about the error. The search query is configurable via the `searchForProblemQuery` setting, which can include placeholders for the diagnostic code and message. This enables one-click access to external resources without manual typing of search terms.
Unique: Implements configurable browser search via the `searchForProblemQuery` setting, allowing developers to customize the search engine and query format. Supports placeholders for diagnostic code and message to enable targeted searches.
vs alternatives: Faster than manually typing search queries because it uses the diagnostic code and message directly, though it requires upfront configuration of the search query template and depends on search result relevance.
Provides a command (`errorLens.toggleWorkspace`) that enables or disables Error Lens decorations for the current workspace, allowing developers to temporarily disable the extension for specific workspaces without uninstalling it. The workspace toggle state is stored in workspace-specific VS Code settings and persists across sessions. This enables different diagnostic visualization preferences for different projects.
Unique: Implements workspace-level toggling via the `errorLens.toggleWorkspace` command, allowing developers to enable or disable Error Lens for specific workspaces without affecting global settings. Toggle state persists in workspace settings.
vs alternatives: More flexible than global enable/disable because it allows different diagnostic visualization preferences for different projects, though it requires manual toggling per workspace and does not support selective disabling of specific decorations.
Provides a command (`errorLens.toggle`) that globally enables or disables all Error Lens decorations (inline messages, line highlighting, gutter icons, status bar) with a single command. The toggle state is stored in VS Code settings and persists across sessions. This allows developers to quickly disable Error Lens without uninstalling the extension, useful for temporary focus or testing.
Unique: Implements a single global master toggle via the `errorLens.toggle` command that affects all decorations simultaneously, stored in VS Code settings and accessible via command palette. Provides quick on/off control without uninstalling.
vs alternatives: Simpler than uninstalling and reinstalling the extension because it preserves all settings and can be toggled quickly, though it does not support selective disabling of specific decoration types.
Provides a command (`errorLens.toggleInlineMessage`) that enables or disables only the inline message text display while keeping other decorations (line highlighting, gutter icons) visible. The toggle state is stored in the `messageEnabled` setting and persists across sessions. This allows developers to reduce text clutter while maintaining visual indicators of diagnostic presence.
Unique: Implements independent toggling of inline message display via the `errorLens.toggleInlineMessage` command, allowing developers to disable text messages while keeping visual indicators. Provides granular control over decoration visibility.
vs alternatives: More flexible than global disable because it allows selective disabling of inline messages while keeping other decorations visible, enabling customized diagnostic visualization per developer preference.
Provides a command (`errorLens.updateEverything`) that manually refreshes all Error Lens decorations and invalidates internal caches, forcing a re-render of all diagnostic visualizations. The command accepts an optional parameter `kind` with values 'update' (refresh decorations) or 'clear' (clear all decorations). This allows developers to recover from display glitches or stale decoration states without reloading the editor.
Unique: Implements manual decoration refresh and cache invalidation via the `errorLens.updateEverything` command with optional `kind` parameter, allowing developers to recover from display glitches without reloading the editor. Provides both update and clear modes.
vs alternatives: Faster than reloading the editor because it only refreshes Error Lens decorations without restarting VS Code, though it is a workaround for underlying issues and should not be needed in normal operation.
Displays small icon indicators in the editor gutter (left margin) at lines containing diagnostics, providing a visual marker without consuming inline space. Icons are rendered via VS Code's gutter decoration API and serve as a compact alternative to full-line highlighting for quickly locating problem lines. The gutter icons are styled consistently with VS Code's theme and severity level.
Unique: Renders severity-specific icons in the editor gutter using VS Code's gutter decoration API, providing a space-efficient alternative to inline messages and line highlighting. Icons are theme-aware and respect VS Code's color scheme.
vs alternatives: More compact than inline messages and full-line highlighting, making it suitable for developers with limited screen space or those preferring minimal visual decoration while still maintaining diagnostic visibility.
