Headless Client/Configuration File
Headless Clients have a lot of configuration potential. To achieve this a configuration file is used. Configuration files are written in JSON.
Default Configuration File
A default configuration file can be found within the Headless Client installation directory's Config subdirectory. It is named DefaultConfig.json.
Creating your own Configuration File
To get started configuring things, copy the DefaultConfig.json file to a new file called Config.json. This will be automatically picked up when you run a Headless Client. Once copied we recommend editing the comment property to be something which describes the function of this file. Its value from the default file is incorrect so give it a comment which reflects what you intend to use it with.
After this you can proceed to edit your configuration file, following the Configuration File Format.
Using multiple configuration files
When running Neos.exe you can use the command line option -c to specify a configuration file. This lets you maintain multiple configuration files for multiple projects or events. For example you could create and use:
Neos.exe -c Config/CoolConvention.json- For a large Convention or eventNeos.exe -c Config/SeriousBusinessMeeting.json- For a very serious business meeting.
It's up to you but feel free to write and use as many files as you'd like.
