`google_calendar` shows `&lt;` instead of "<" in `{summary}`

[Václav Kubernát]

Describe the bug
Using google_calendar with an event title that has a "<" in it, it shows as <

Your py3status version
py3status version 3.44 (python 3.10.5) on i3

To Reproduce

1. Add module google_calendar
2. Configure google_calendar's {format_event} to include the event title ({summary})
3. Have a google event that includes "<"
4. py3status shows < instead of the less than sign

Expected behavior
py3status should show the less than sign.

Screenshots
This is how the event looks on the google calendar website:

This is how it shows up in py3status:

Additional context
This is my configuration for google_calendar:

google_calendar {
    time_to_max = 99999
    events_within_hours = 48
    format_event = "[\?if=!is_current [\?color=lime {summary}][ {format_timer}]]"
    format_timer = "\?color=time (in [\?if=days {days}d ][\?if=hours {hours}h ][\?if=minutes {minutes}m])"
}

I have tested that f6da6b8 does introduce this bug. The commit before that works fine (it also had something to do with HTML formatting)

Does it work fine if you add markup = "pango" to your google_calendar config?

[Václav Kubernát]

Yes, that helps. Thanks! I wasn't aware of the markup setting.

[Václav Kubernát]

I'm not sure if markup = "pango" is just a workaround or if my problem is an actual bug. Feel free to close this issue if it's not a bug.

I'll have to check if somehow the module could detect pango markup config and escape html only when pango is used

[lasers]

Here's an idea... For starters, users could manually specify which placeholders to escape html.

Just some more info: since 3.47 (and probably #2146), using the markup = pango workaround makes any event name that has a < appear completely empty:

Dropping markup = pango makes everything work fine again:

I see that the patch has been present since October. I guess there weren't any less than signs in my event names lately. But at least someone might find this information useful if they used the workaround.
