Pulsar

RSS Aggregator for Gemini Protocol

Simple RSS feed converter to static Gemtext format, useful for news portals or localhost reading

Usage

1. git clone https://github.com/YGGverse/Pulsar.git
2. cp example/crawler.json crawler.json - setup your feed locations
3. php src/crawler.php - grab feeds manually or using crontab

Config

Configuration file supports multiple feed channels with custom settings:

• source - string, filepath or URL to the valid RSS feed
• target - string, relative or absolute path to Gemtext dumps
• item
  • limit - integer, how many items to display on page generated
  • template - string, custom pattern for feed item, that supports following macros
    • {nl} - new line separator
    • {link} - item link
    • {guid} - item guid
    • {pubDate} - item pubDate, soon with custom time format e.g. {pubDate:Y-m-d H:s}
    • {title} - item title
    • {description} - item description

Resulting files could be placed to any local folder (for personal reading) or shared with others (using gmid, twins or any other server)

Server

Pulsar comes with build-in Titan-II server implementation.

It's especially useful for Yggdrasil users, who wish to host their feeds using plain IPv6 0200::/7 addresses as the CN record. Build-in server contain this feature implemented from the box.

Setup

• cd Pulsar - navigate to the project folder
• composer update - download server dependencies with Composer
• mkdir server/127.0.0.1 - init server location (you can define any other destination, server just git ignored)
• cp example/host.json server/127.0.0.1/host.json - copy configuration example to the destination folder
• cd server/127.0.0.1 - navigate to server folder created and generate new self-signed certificate

On example above, certificate could be generated with following command:

openssl req -x509 -newkey rsa:4096 -keyout key.rsa -out cert.pem -days 365 -nodes -subj "/CN=127.0.0.1"

• tip: for IPv6 address, just skip square brackets from CN value

Launch

• php src/server.php server/127.0.0.1 - supported relative or absolute paths (for systemd service)

Open gemini://127.0.0.1 in Gemini browser!

Autostart

Launch server as systemd service

Following example means you have Pulsar installed in home directory of pulsar user (useradd -m pulsar)

sudo nano /etc/systemd/system/pulsar.service - create new unit file:

[Unit]
After=network.target

[Service]
Type=simple
User=pulsar
ExecStart=/usr/bin/php /home/pulsar/Pulsar/src/server.php /home/pulsar/Pulsar/server/127.0.0.1
StandardOutput=file:/home/pulsar/Pulsar/server/127.0.0.1/debug.log
StandardError=file:/home/pulsar/Pulsar/server/127.0.0.1/error.log
Restart=on-failure

[Install]
WantedBy=multi-user.target

• sudo systemctl daemon-reload - reload systemd configuration
• sudo systemctl enable pulsar - enable Pulsar service on system startup
• sudo systemctl start pulsar - start Pulsar server
