Earl Gemini Server

A simple Gemini server written in Kotlin. Currently in alpha.

Generating a certificate

To generate the key, run the following command (requires keytool):

keytool -genkey -alias <alias> -keyalg RSA -keypass <key passphrase> -storepass <store passphrase> -keystore keystore.jks

When prompted for "First and Last Name", enter your hostname.

Running the server

1. Copy earl_config_sample to desired directory. By default, Earl will search ~/.earl_config
2. From the project root directory, run ./gradlew run. If you chose to put your config in a different directory, you can specify that directory by running ./gradlew run --args='/path/to/.earl_config'

Building the server

Simply run ./gradlew build. The resultant distributable will be located in earl/build/distributions. To start Earl, simply run bin/earl from the root of the extracted distributable bundle.
