To customize the WezTerm tab bar, you configure a Lua format-tab-title handler and a process_icons map. This setup provides icon-based titles, directory-aware names, and real-time process status for each tab.

Yes, you can display Nerd Font icons by mapping process names to icons within a Lua process_icons table. The format-tab-title handler then renders these icons in the tab bar to help you identify active tasks quickly.

You can make WezTerm tab titles show the current directory and status by implementing a Lua format-tab-title handler. This handler dynamically extracts the leaf directory and process status to update the tab bar text.

Yes, WezTerm requires a Nerd Font installed in your terminal environment to render the process icons correctly. Without a Nerd Font, the icon glyphs in your tab titles will not display as intended.

The best way to manage WezTerm tab titles across projects is using a Lua format-tab-title handler. It dynamically updates the tab bar with the active folder and per-tab status, reducing confusion when switching contexts.

WezTerm tab icons fail to show correctly if your terminal lacks a Nerd Font or the process_icons map is misconfigured. Ensure your font supports the required glyphs and the Lua handler maps process names properly.
