Junos Extension for Visual Studio Code

Junos extension for Visual Studio Code is a language server that provides auto-completion, validation, and syntax highlighting for Junos.

Features

The language server has the following language features:

• Completion
• Syntax validation
• Syntax highlighting
• Go To Definition
  • interface
  • prefix-list
  • policy-statement
  • community
  • as-path
  • as-path-group
  • firewall-filter
  • NAT pool (source-pool, destination-pool, dns-alg-pool, overload-pool, security nat ... then (source|destination)-nat pool)
  • address and address-set in global and zone-specific address books, including security nat ... match (source|destination)-address and security policies ... match (source|destination)-address
  • application in security policies ... match application

Requirements

• Visual Studio Code 1.100.0 or later

Supported Junos

Completion and validation are driven by the NETCONF schema (xsd) of Junos 23.4, converted into a parser with junoser. Syntax of other platforms is merged into the schema:

• security, chassis cluster and chassis high-availability of vSRX 22.4
• poe of EX 18.1
• ethernet-switching-options of 12.1

Platform differences are not modeled; a statement unsupported on the target device may still be reported as valid. Syntax introduced after the releases above is reported as invalid.
