• Provides completion for Logstash pipeline configuration files (sections, plugins, options), depending current cursor position.
  For example, if cursor is inside grok filter, options for grok filter are suggested.
• All completion data is generated from official Logstash documentation
• Options for a plugin are sorted : first required options, then optional specific options, and finally optional common options
• When you preselect an item, a link to official documentation, a short description and an example (if available) are provided
• If you choose a completion item, a code snippet is automatically inserted with relevant content:
  • for a plugin, inserted snippet is the plugin block and all its required options
  • for an option, inserted snippet is based on option type (string, boolean, number, string_duration, array, hash)
• Provides completion for if statement
• Provides documentation when hover on a section, a plugin or an option
• Provides document formatting and document range formatting on a Logstash pipeline configuration file
• Provides completion for Elasticsearch index template json files, based on a json schema
• Provides a specific index template json schema for Elasticsearch 6.x and 7.x
• Provides "logstash.version" configuration setting to choose Logstash version (for completion)
• Provides "Set Logstash Version" command (shortcut: Ctrl+Shift+L) to change Logstash version setting
• Supported Logstash versions: 6.8, 7.2, 7.5
• Following file patterns are automatically associated to Logstash language:
  • *logstash.conf
  • *logstash.conf.j2
  • *logstash.conf.template
  • logstash-*.conf
• Following file patterns are automatically associated to Elasticsearch index template json schema:
  • *elasticsearch-template.json
  • *elasticsearch-template-es7x.json
  • *elasticsearch-template-es6x.json

For now, only this format style is supported for Logstash configuration files:

filter {
	tcp {
		port => 12345
	}
}

This format style is not supported:

filter 
{
	tcp 
	{
		port => 12345
	}
}

Neither this one:

filter { tcp { port => 12345 } }
