Flag images are sourced from here: https://flaglog.com/country-codes Placing the flags in a subdirectory of `./static` for good housekeeping requires a change to the location matching of the `nginx` configuration; otherwise they will not be found. Change: ``` location ~ /(?![^/]*\.(?:css|js|png|html)(?:$|\?)) { ``` to: ``` location ~ /(?!([^/]*|flags/[^/]*)\.(?:css|js|png|html)(?:$|\?)) { ```

The code has been rebased and country flags added to the display:

suggestion, also provide systemd timer for updating geoip db. |

This would be a lot simpler if it used unicode flag sequences instead of needing to serve all the PNGs. These are pretty simple to construct -- you just write the two-letter country code using regional letter sequences instead of normal letters, and it gets rendered as a flag: regional_indicators = {'a': '🇦', 'b': '🇧', 'c': '🇨', 'd': '🇩', 'e': '🇪', 'f': '🇫', 'g': '🇬', 'h': '🇭', 'i': '🇮', 'j': '🇯', 'k': '🇰', 'l': '🇱', 'm': '🇲', 'n': '🇳', 'o': '🇴', 'p': '🇵', 'q': '🇶', 'r': '🇷', 's': '🇸', 't': '🇹', 'u': '🇺', 'v': '🇻', 'w': '🇼', 'x': '🇽', 'y': '🇾', 'z': '🇿'}
# Or if you prefer, something like:
regional_indicators = { chr(ord('a') + i): chr(ord('🇦') + i) for i in range(0, 26) }
def flag(cc):
return ''.join(regional_indicators[c] for c in cc)>>> flag('ca')
'🇨🇦' |
That would have been the obvious way to do it, were it not that Windows 10/11 won't render flag characters by design: |

A much better explanation of the problems with flag emoji can be found here: |
I just noticed that this code doesn't even do the right thing for me on Linux, so I'm curious which combination of terminal and font assortment you are using. This is what I see with
