# fosdem2gemini
|
||||
|
||||
Convert the FOSDEM schedule to gemtext (text/gemini) format, to be served with Gemini.
|
||||
Convert the [FOSDEM](https://fosdem.org/) schedule to gemtext
|
||||
(`text/gemini`) format, to be served via
|
||||
[Gemini](https://en.wikipedia.org/wiki/Gemini_(protocol)).
|
||||
|
||||
## Installation
|
||||
|
||||
Download the program. Be sure you have the
|
||||
[lxml](https://lxml.de/library. Edit sample-index.gmi to suit your
|
||||
needs and rename it index.gmi. Then run the program periodically, for
|
||||
instance through cron:
|
||||
|
||||
```
|
||||
# FOSDEM
|
||||
26 1,5,9,13,17,21 * * * (cd /path/to/FOSDEM; make all)
|
||||
```
|
||||
|
||||
## Technical details
|
||||
|
||||
The FOSDEM schedule is publically available (from the schedule
|
||||
management system Pentabarf) as a XML file (whch we can retrieve with,
|
||||
for instance, `wget https://fosdem.org/2021/schedule/xml`). The use of
|
||||
a structured format allows us to convert it easily.

# FOSDEM schedule
|
||||
|
||||
A non-official Gemini version of FOSDEM schedule for the 2021 "COVID edition".
|
||||
|
||||
=> allevents.gmi All events, sorted by date and time
|
||||
=> allrooms.gmi All "rooms", with their events
|
||||
|
||||
=> https://fosdem.org/ FOSDEM official page
|
||||
=> https://fosdem.org/2021/schedule/ FOSDEM official schedule
|
||||
|
||||
The schedule here is automatically produced from the FOSDEM "Pentabarf" files.

||||
