# Webseite
|
||||
|
||||
Das Repository enthält die Webseite das Vereins "Hackspace Jena". Der größte
|
||||
Teil der Webseite ist statisches HTML, ergänzt um einige dynamische
|
||||
Elemente zur Anzeige des Raumstatuses und der aktuellen Termine.
|
||||
|
||||
## Installation
|
||||
|
||||
Zum Betrieb der Webseite ist ein Webserver und PHP notwendig. Die
|
||||
Auswertung der Termine erfolgt mittels der VObject Bibliothek von
|
||||
[https://sabre.io](https://sabre.io), welche auch in Nextcloud enthalten
|
||||
ist. Debian stellt die Bibliothe in dem Paket php-sabre-vobject bereit. Nach
|
||||
der Installation und Konfiguration des Websevers inklusive PHP wird das Repo
|
||||
in das Dokumentroot des Webservers kopiert.
|
||||
|
||||
### Installationsschritte
|
||||
|
||||
```bash
|
||||
# install calendar event exporter
|
||||
sudo install -o0 -g0 -m444 etc/systemd/calendar-events-exporter.* /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable --now calendar-events-exporter.timer
|
||||
|
||||
# install nginx config
|
||||
sudo install -o0 -g0 -m444 etc/nginx/kraut.space.conf /etc/nginx/sites-available/
|
||||
sudo ln -s ../sites-available/kraut.space.conf /etc/nginx/sites-enabled/

sudo systemctl reload nginx

Mit Begin der Corona-Pandemie waren auch wir gezwungen unsere
|
||||
Aktivitäten in einen virtuellen Raum zu verlegen. Dazu
|
||||
betreiben wir zwei wöchentliche virtuelle Treffpunkte. Daneben
|
||||
nutzen wir zur Kommunikation hauptsächlich einen Raum in der
|
||||
Matrix. Du kannst dort gern Kontakt zu uns aufnehmen.
|
||||
Unser hauptsächlicher Treffpunkt ist der Krautspace in der
|
||||
Krautgasse 26 im Zentrum von Jena. Nachdem wir wegen der
|
||||
Corona-Pandemie vorübergehend auf virtuelle Räume
|
||||
ausweichen mussten, treffen sich mittlerweile alle unsere Runden
|
||||
wieder vor Ort.

Anfang Juni 2022 haben wir die bisherige Mailingliste durch ein

|

abgelöst. Alle Runden treffen sich wieder live in der

Krautgasse. Bei Chaostreff und LUG bieten wir weiterhin die

# Zap Calendar iCalendar Library
|
||||
|
||||
(https://github.com/zcontent/icalendar)
|
||||
|
||||
The Zap Calendar iCalendar Library is a PHP library for supporting the iCalendar (RFC 5545) standard.
|
||||
|
||||
This PHP library is for reading and writing iCalendar formatted feeds and
|
||||
files. Features of the library include:
|
||||
|
||||
- Read AND write support for iCalendar files
|
||||
- Object based creation and manipulation of iCalendar files
|
||||
- Supports expansion of RRULE to a list of repeating dates
|
||||
- Supports adding timezone info to iCalendar file
|
||||
|
||||
All iCalendar data is stored in a PHP object tree.
|
||||
This allows any property to be added to the iCalendar feed without
|
||||
requiring specialized library function calls.
|
||||
With power comes responsibility. Missing or invalid properties can cause
|
||||
the resulting iCalendar file to be invalid. Visit [iCalendar.org](http://icalendar.org) to view valid
|
||||
properties and test your feed using the site's [iCalendar validator tool](http://icalendar.org/validator.html).
|
||||
|
||||
Library API documentation can be found at http://icalendar.org/zapcallibdocs
|
||||
|
||||
See the examples folder for programs that read and write iCalendar
|
||||
files. At its simpliest, you need to include the library at the top of your program:
|
||||
|
||||
```php
|
||||
require_once($path_to_library . "/zapcallib.php");
|
||||
```
|
||||
|
||||
Create an ical object using the ZCiCal object:
|
||||
|
||||
```php
|
||||
$icalobj = new ZCiCal();
|
||||
```
|
||||
|
||||
Add an event object:
|
||||
|
||||
```php
|
||||
$eventobj = new ZCiCalNode("VEVENT", $icalobj->curnode);
|
||||
```
|
||||
|
||||
Add a start and end date to the event:
|
||||
|
||||
```php
|
||||
// add start date
|
||||
$eventobj->addNode(new ZCiCalDataNode("DTSTART:" . ZCiCal::fromSqlDateTime("2020-01-01 12:00:00")));
|
||||
|
||||
// add end date
|
||||
$eventobj->addNode(new ZCiCalDataNode("DTEND:" . ZCiCal::fromSqlDateTime("2020-01-01 13:00:00")));
|
||||
```
|
||||
|
||||
Write the object in iCalendar format using the export() function call:
|
||||
|
||||
```php
|
||||
echo $icalobj->export();
|
||||
```
|
||||
|
||||
This example will not validate since it is missing some required elements.
|
||||
Look at the simpleevent.php example for the minimum # of elements
|
||||
needed for a validated iCalendar file.
|
||||
|
||||
To create a multi-event iCalendar file, simply create multiple event objects. For example:
|
||||
|
||||
```php
|
||||
$icalobj = new ZCiCal();
|
||||
$eventobj1 = new ZCiCalNode("VEVENT", $icalobj->curnode);
|
||||
$eventobj1->addNode(new ZCiCalDataNode("SUMMARY:Event 1"));
|
||||
...
|
||||
$eventobj2 = new ZCiCalNode("VEVENT", $icalobj->curnode);
|
||||
$eventobj2->addNode(new ZCiCalDataNode("SUMMARY:Event 2"));
|
||||
...
|
||||
```
|
||||
|
||||
To read an existing iCalendar file/feed, create the ZCiCal object with a string representing the contents of the iCalendar file:
|
||||
|
||||
```php
|
||||
$icalobj = new ZCiCal($icalstring);
|
||||
```
|
||||
|
||||
Large iCalendar files can be read in chunks to reduce the amount of memory needed to hold the iCalendar feed in memory. This example reads 500 events at a time:
|
||||
|
||||
```php
|
||||
$icalobj = null;
|
||||
$eventcount = 0;
|
||||
$maxevents = 500;
|
||||
do
|
||||
{
|
||||
$icalobj = newZCiCal($icalstring, $maxevents, $eventcount);
|
||||
...
|
||||
$eventcount +=$maxevents;
|
||||
}
|
||||
while($icalobj->countEvents() >= $eventcount);
|
||||
```
|
||||
|
||||
You can read the events from an imported (or created) iCalendar object in this manner:
|
||||
|
||||
```php
|
||||
foreach($icalobj->tree->child as $node)
|
||||
{
|
||||
if($node->getName() == "VEVENT")
|
||||
{
|
||||
foreach($node->data as $key => $value)
|
||||
{
|
||||
if($key == "SUMMARY")
|
||||
{
|
||||
echo "event title: " . $value->getValues() . "\n";
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Known Limitations
|
||||
|
||||
- Since the library utilizes objects to read and write iCalendar data, the
|
||||
size of the iCalendar data is limited to the amount of available memory on the machine.
|
||||
The ZCiCal() object supports reading a range of events to minimize memory
|
||||
space.
|
||||
- The library ignores timezone info when importing files, instead utilizing PHP's timezone
|
||||
library for calculations (timezones are supported when exporting files).
|
||||
Imported timezones need to be aliased to a [PHP supported timezone](http://php.net/manual/en/timezones.php).
|
||||
- At this time, the library does not support the "BYSETPOS" option in RRULE items.
|
||||
- At this time, the maximum date supported is 2036 to avoid date math issues
|
||||
with 32 bit systems.
|
||||
- Repeating events are limited to a maximum of 5,000 dates to avoid memory or infinite loop issues
