Diagnostics

Athas shows diagnostics in a dedicated bottom-pane Problems view.

Open Diagnostics

You can open the diagnostics pane from any of these entry points:

• The diagnostics indicator in the footer
• Cmd/Ctrl+Shift+J
• Command Palette: View: Show Diagnostics

If you do not use diagnostics, you can disable the surface entirely in Settings > Features.

What You See

The pane summarizes all current problems and keeps a live count in the footer.

• Errors, warnings, and info diagnostics are shown together
• The footer badge turns into a warning-colored count when problems exist
• Clicking a problem jumps to its file and position
• Editor gutter markers reflect the highest-severity problem on each line

Search, Filter, and Group

Athas lets you narrow the list without leaving the pane:

• Search by message, source, code, file path, or line and column
• Filter by severity
• Filter to only the current file
• Filter by diagnostic source from the context menu
• Group by file, severity, or not at all
• Sort by severity, file, or position

Quick Fixes and Actions

Right-click any problem to open its action menu.

Available actions include:

• Quick fixes exposed by the active language tooling
• Go to Problem
• Copy Message
• Copy Location
• Copy Full Details
• Toggle wrapped messages

Pane Controls

The diagnostics pane supports the same bottom-pane workflow as terminal and references:

• Resize it vertically from the top edge
• Open it full screen
• Switch between full-width and editor-width modes from the header context menu
