Weather widget crashes: ValueError: invalid literal for int() with base 10: '100.0'

[alex-sitnikov]

Description

YASB v1.8.7 crashes immediately on startup due to the weather widget failing to parse precipitation chance values.

Error

Traceback (most recent call last):
  File "D:\a\yasb\yasb\src\core\widgets\yasb\weather.py", line 69, in <lambda>
  File "D:\a\yasb\yasb\src\core\widgets\yasb\weather.py", line 465, in _update_label
ValueError: invalid literal for int() with base 10: '100.0'

Root Cause

In _update_label, the tooltip code does:

rain = self._weather_data["{hourly_chance_of_rain}"]
snow = self._weather_data["{hourly_chance_of_snow}"]

if rain != "N/A" and snow != "N/A" and (int(rain.rstrip("%")) > 0 or int(snow.rstrip("%")) > 0):

The weatherapi.com API sometimes returns chance_of_rain / chance_of_snow as a float (e.g. 100.0) instead of an integer. When process_weather_data formats this as "100.0%", and then _update_label tries int("100.0"), it throws a ValueError.

Suggested Fix

Replace int(rain.rstrip("%")) with int(float(rain.rstrip("%"))) (same for snow). This handles both integer and float string representations.

if rain != "N/A" and snow != "N/A" and (int(float(rain.rstrip("%"))) > 0 or int(float(snow.rstrip("%"))) > 0):
    precip: list[str] = []
    if int(float(rain.rstrip("%"))) > 0:
        precip.append(f"Rain {rain}")
    if int(float(snow.rstrip("%"))) > 0:
        precip.append(f"Snow {snow}")

Environment

• YASB version: 1.8.7
• Installed via: Scoop
• OS: Windows 11
• Weather API: weatherapi.com

Reproduction

The crash is 100% reproducible when chance_of_rain or chance_of_snow is returned as 100.0 by the API. The crash happens every 10 minutes when weather data is fetched, and also on startup.

Thank you for reporting this issue and providing such a detailed analysis with the root cause and suggested fix! 👍

This issue appears to be a duplicate of #687, which reports the exact same ValueError: invalid literal for int() with base 10 crash in the weather widget when the weatherapi.com API returns precipitation chance values as floats (e.g., 100.0 or 0.0) instead of integers.

Your analysis and suggested fix using int(float(rain.rstrip("%"))) is excellent and aligns with what's being discussed in the original issue. Please follow #687 for updates on the resolution of this bug.

In the meantime, as a temporary workaround, you can:

• Remove or comment out the weather widget from your config.yaml to allow YASB to start
• Wait for the upcoming fix which should handle both integer and float precipitation values
