LuaBugViewer
A modern, modular Lua error catcher for WoW 3.3.5a. Captures errors as they happen and shows them in a clean viewer window, with full copy-paste support so you can paste a clean stack trace.
A drop-in replacement for BugGrabber + BugSack, with no Ace3 / LibStub / LibDataBroker dependencies.

What it does
- Captures every Lua error via a properly chained
seterrorhandler- Blizzard's default error popup (and anything else hooked in) still runs - Also captures
ADDON_ACTION_BLOCKEDandADDON_ACTION_FORBIDDENevents - Deduplicates repeats: identical errors show as a single row with an
xNcounter - Throttles runaway error loops: pauses capture for 60s after more than 20 errors/sec
- One-line yellow chat notification per new error (duplicates stay quiet)
- "Lua Errors" button on the ESC (Game) menu with an unread-count badge
- Two-pane viewer: error list on the left, full stack trace and locals on the right - both panes are selectable for Ctrl+C copy

How errors are stored
Errors live in memory for the current session only - they're not persisted to SavedVariables and /reload wipes the log. This keeps the SavedVariables file tiny and avoids the bloat that haunted long-running BugSack databases. Only your settings (chat-notification toggle, throttle limits, max stored count) persist across sessions in LuaBugViewerDB.
The log is capped at 100 errors by default; oldest entries drop off as new ones arrive.
Configuration
Settings live in the LuaBugViewerDB SavedVariable. Defaults:
| Key | Default | Meaning |
|---|---|---|
notifyInChat | true | Print a yellow [LBV] line on every new error |
throttleRate | 20 | Errors per second that triggers a capture pause |
throttleCooldown | 60 | Seconds capture stays paused after a burst |
maxStored | 100 | Hard cap on the session log; oldest are dropped |
