Hey Ripli, I just sketched a gadget that turns my debugging board into a real‑time error‑detecting assistant—imagine a regex‑powered UI that maps bugs to patterns and even scores them like a leaderboard. What do you think?
Ripli
Sounds like a regex‑driven UI that scans stack traces and spits out severity tags, then updates a leaderboard. I’d first ask, does it handle false positives? And how does it decide the scoring algorithm? If the pattern matching is tight, it’ll be a killer debugging tool, but any looseness and you’ll just get noise. Also, the interface needs to be minimal – the last thing I want is a cluttered dashboard. Keep the prompt concise and the regex tight. Good sketch, but let’s see the code.
Contriver
Sure thing, here’s a lean prototype in Python. It scans a stack trace, tags each line with a severity, and keeps a quick leaderboard in the console.
```python
import re
from collections import Counter
# Patterns → severity and base score
PATTERNS = [
(r"(?i)NullPointerException", ("CRITICAL", 10)),
(r"(?i)IndexOutOfBoundsException", ("MAJOR", 7)),
(r"(?i)IOException", ("MINOR", 4)),
(r"(?i)RuntimeError", ("MEDIUM", 6)),
(r"(?i)AssertionError", ("CRITICAL", 10)),
]
def classify_line(line):
for pat, (sev, score) in PATTERNS:
if re.search(pat, line):
return sev, score
return ("UNKNOWN", 1)
def analyze(trace):
counts = Counter()
total_score = 0
for ln in trace.splitlines():
sev, score = classify_line(ln)
counts[sev] += 1
total_score += score
return counts, total_score
def leaderboard(counts):
print("\n--- Severity Leaderboard ---")
for sev, num in counts.most_common():
print(f"{sev:10s} : {num}")
# Example usage
stack = """Traceback (most recent call last):
File "app.py", line 12, in <module>
main()
File "app.py", line 8, in main
do_something()
IndexOutOfBoundsException: list index out of range
RuntimeError: something bad happened
"""
counts, score = analyze(stack)
leaderboard(counts)
print(f"\nTotal severity score: {score}")
```
The regexes are tight, the UI is just console text, and you can tweak the `PATTERNS` list for your own stack traces. Let me know if you want a GUI wrapper or integration into your IDE.
Ripli
Nice prototype, but those regexes are hard‑coded. A mapping of exception types to severity would be cleaner, and a proper stack‑trace parser would catch nested traces. Console leaderboard works for now, but a tiny GUI or IDE plugin would make the feedback more actionable. Interested in a quick demo of that?
Contriver
Got it, let’s switch to a tiny Tkinter pop‑up. It pulls the same logic but shows a clean listbox and a severity bar. Here’s the skeleton you can paste into a .py file and run:
```python
import tkinter as tk
import re
from collections import Counter
# Same PATTERNS list from before
def analyze(trace):
counts = Counter()
for ln in trace.splitlines():
for pat, (sev, _) in PATTERNS:
if re.search(pat, ln):
counts[sev] += 1
break
return counts
def show_gui(counts):
root = tk.Tk()
root.title("Bug Severity Dashboard")
listbox = tk.Listbox(root, width=30)
for sev, num in counts.most_common():
listbox.insert(tk.END, f"{sev:10s} : {num}")
listbox.pack(padx=10, pady=10)
root.mainloop()
# Example stack trace
stack = """Traceback (most recent call last):
File "app.py", line 12, in <module>
main()
File "app.py", line 8, in main
do_something()
IndexOutOfBoundsException: list index out of range
RuntimeError: something bad happened"""
counts = analyze(stack)
show_gui(counts)
```
Run it, and you’ll see a tiny window with the leaderboard. If you need an IDE plugin, we can spin a VSCode extension later, but this shows the concept. Let me know if you want to tweak colors or add a severity bar.
Ripli
That pops up clean enough, but the severity bar is missing; just a listbox. If you want a visual cue, add a progress bar per severity or color‑code the rows. Also, consider caching the patterns in a compiled regex list for speed, especially if you’ll run it on long logs. For a quick demo, run it, tweak the colors, and you’ll have a usable dashboard.

```python
import tkinter as tk
import tkinter.ttk as ttk
import re
from collections import Counter
# Compile patterns once
PATTERNS = [
(re.compile(r"(?i)NullPointerException"), ("CRITICAL", 10, "#ff4d4d")),
(re.compile(r"(?i)IndexOutOfBoundsException"), ("MAJOR", 7, "#ff9933")),
(re.compile(r"(?i)IOException"), ("MINOR", 4, "#ffcc33")),
(re.compile(r"(?i)RuntimeError"), ("MEDIUM", 6, "#ffeb99")),
(re.compile(r"(?i)AssertionError"), ("CRITICAL", 10, "#ff4d4d")),
]
def analyze(trace):
counts = Counter()
for ln in trace.splitlines():
for pat, (sev, _, _) in PATTERNS:
if pat.search(ln):
counts[sev] += 1
break
return counts
def show_gui(counts):
root = tk.Tk()
root.title("Bug Severity Dashboard")
for sev, num in counts.most_common():
# Find color
color = next(col for p, (s, _, col) in PATTERNS if s == sev)
frame = tk.Frame(root, bg=color, padx=5, pady=2)
frame.pack(fill='x', padx=10, pady=3)
lbl = tk.Label(frame, text=f"{sev:10s} : {num}", bg=color)
lbl.pack(side='left')
bar = ttk.Progressbar(frame, maximum=num, value=num, length=200)
bar.pack(side='right')
root.mainloop()
# Demo stack trace
stack = """Traceback (most recent call last):
File "app.py", line 12, in <module>
main()
File "app.py", line 8, in main
do_something()

counts = analyze(stack)
show_gui(counts)
```
Run this script, and you’ll see each severity row shaded in a matching color with a progress bar that fills proportionally to its count. This should give you a quick, visual, and actionable dashboard.
