The PR is finished or stull in draft? :)

[Damien-VS]

I believe it is finnished.
I just closed/reopen after thinking about a bug in it during the night. This time, I slept on it a fex times, so it should be good 😄 .

Do you need some screens + annotations in here to parse through the thing ?
Thanks for your time 🙏

[scraly]

First of all, thanks for your work! :-)
Yes if you can add some screen or anything else it will be helpful :-)

[Damien-VS]

Some context :

we needed to have a CFP list, so I ended up rewriting the Python parser in .js.
Both to fix some bugs and also to add the cfp list in a separated .json file.

As the format changed a bit, I also fixed the frontend + a bug that bothered me much (see below)

Parser

Some unparsed events are now being parsed correctly (from 1057 events to 1095 at this date)
This events are now enriched with the CFP data from the badge.
The timestamp is now standard json/js format, in (millis, not in seconds)

event json format updated from this :

[{
    "name": "Full Stack Europe",
    "date": [
      1697587200,
      1697760001
    ],
    "hyperlink": "https://fullstackeurope.com/2023",
    "location": "Antwerp (Belgium) ",
    "misc": "<a href=\"https://docs.google.com/forms/d/e/1FAIpQLSdgQjf39QepP07gLE88g7-Cn7Xdfast_mHVSUp25CfpjAM2uw/viewform\"><img alt=\"CFP Full Stack Europe 2023\" src=\"https://img.shields.io/static/v1?label=CFP&message=until%2030-June-2023&color=green\"></a>"
  },

to this :

[{
    "name": "Full Stack Europe",
    "date": [
      1697580000000,
      1697752800000
    ],
    "hyperlink": "https://fullstackeurope.com/2023",
    "location": "Antwerp (Belgium)",
    "misc": "<a href=\"https://docs.google.com/forms/d/e/1FAIpQLSdgQjf39QepP07gLE88g7-Cn7Xdfast_mHVSUp25CfpjAM2uw/viewform\"><img alt=\"CFP Full Stack Europe 2023\" src=\"https://img.shields.io/static/v1?label=CFP&message=until%2030-June-2023&color=green\"></a>",
    "cfp": {
        "link": "https://docs.google.com/forms/d/e/1FAIpQLSdgQjf39QepP07gLE88g7-Cn7Xdfast_mHVSUp25CfpjAM2uw/viewform",
        "until": "30-June-2023",
        "untilDate": 1711494000000
    },
    "status": "open"
},
...
]

A new file named all-cfps.json is now generated with CFP's ordered by ascending end date.
format :

[
{
    "link": "https://docs.google.com/forms/d/e/1FAIpQLSdgQjf39QepP07gLE88g7-Cn7Xdfast_mHVSUp25CfpjAM2uw/viewform",
    "until": "30-June-2023",
    "untilDate": 1711494000000,
    "conf": {
        "name": "Full Stack Europe",
        "date": [1697580000000, 1697752800000],
        "hyperlink": "https://fullstackeurope.com/2023",
        "status": "open",
        "location": "Antwerp (Belgium)"
    }
}
,...
]

UI changes

Dates with lots of events (7+) were displayed with very low contrast. Dimmed the effect by half.

Thx, it's really awesome!

Just a question, why the "status" is not a cfp's field? Because it's the CFP which is open and not the conference, isn't it? :-)

[scraly]

Is it the status of a CFP or a conference? This status should always be equals to "open"?
Thx :)

[Damien-VS]

it's the status of the conference.
I defaulted to 'open', but it takes the value expressed before the date

eg: "* [Pixelated] 04-05: myconf ..." --> status = pixelated

BTW, it appears mostly in 2020.md file ... because of covid, I guess

[scraly]

Thanks, I understand and yes we can keep it on order, for example, to add the "canceled" status possibility :)
