SaltStack Toolkit

VS Code extension for working with SaltStack: syntax highlighting, linting, formatting, snippets, navigation, and auto-completion for Salt SLS and Jinja2 files.

Features

Syntax Highlighting

• YAML + Jinja2 combined grammar for .sls files
• Salt-specific highlighting: state IDs, state modules, requisites, salt, pillar, grains
• Standalone Jinja2 grammar for .jinja, .j2 files

Linting (real-time diagnostics)

• Duplicate state IDs
• Unclosed Jinja blocks ({% if %} without {% endif %})
• Tab characters (Salt/YAML requires spaces)
• Empty state blocks (state ID without module call)
• Requisite references to non-existent state IDs
• Trailing whitespace

Formatting (Shift+Alt+F or auto on save)

• Auto-format on save -- enabled by default via editor.formatOnSave (extension sets itself as default formatter for SLS/Jinja)
• Enforce {%- on opening tags -- {% if x %} -> {%- if x %}, {%set%} -> {%- set %} (enabled by default, saltstack.format.enforceDashTags)
• Preserves closing -%} -- existing -%} is never removed: {%- if x -%} stays {%- if x -%}
• Jinja tag spacing normalization: {%if x%} -> {%- if x %}, {{var}} -> {{ var }}
• Comments {# ... #} content is left untouched
• Tabs to spaces
• Trailing whitespace removal
• Collapses multiple consecutive blank lines to one
• Ensures final newline

Navigation

• Outline (Cmd+Shift+O) -- state IDs, modules, includes, Jinja imports/variables
• Go-to-Definition (Cmd+Click) -- Jinja imports/includes, salt:// sources, SLS includes, requisite references, pillar includes
• Hover -- documentation for 55+ state modules, all requisites, Salt builtins (salt, pillar, grains), execution modules (sdb.get, defaults.merge, fast_yaml.hosts, etc.) — 85+ entries total

Auto-completion

• State modules (file.managed, service.running, etc.)
• Module parameters
• Requisites (require, watch, onchanges, etc.)
• Salt execution modules inside salt['...'] and salt.

Snippets (90+)

• Salt state modules: file.managed, pkg.installed, service.running, cmd.run, user.present, docker_container.running, etc.
• Jinja constructs: if, for, set, macro, block, from ... import, etc.
• Salt/Pillar patterns: sdb.get, sdb.get_or_set_hash, grains.filter_by, fast_yaml.hosts, saltutil.runner
• Boilerplates: sls-boilerplate, sls-full, map-jinja

Pillar Support

• Auto-detects pillar files based on saltstack.pillarRoots setting
• Go-to-Definition for pillar includes ({% include "defaults/..." %})
• Hover shows how to access pillar keys from states
• Disables state-specific completions in pillar context

Build

Requirements: Node.js >= 18, npm.

# Install dependencies
npm install

# Compile TypeScript
npm run compile

# Package as .vsix
npx @vscode/vsce@latest package --allow-missing-repository

For development with auto-rebuild on changes:

npm run watch

Install

code --install-extension saltstack-toolkit-<version>.vsix

Or in the IDE: Ctrl+Shift+P -> "Extensions: Install from VSIX..." -> select the .vsix file.

To update, build a new version and install again -- a higher version number installs without --force.

Settings

Add to your settings.json:

{
  "saltstack.stateRoots": [
    "/path/to/salt-states"
  ],
  "saltstack.pillarRoots": [
    "/path/to/pillars/pillar"
  ],
  "saltstack.lint.enabled": true,
  "saltstack.lint.duplicateStateIds": true,
  "saltstack.lint.trailingWhitespace": true,
  "saltstack.lint.tabs": true,
  "saltstack.lint.jinjaBlocks": true,
  "saltstack.format.enforceDashTags": true
}

stateRoots and pillarRoots accept both absolute paths and paths relative to the workspace root. These are used for Go-to-Definition resolution of salt://, {% from %}, {% include %}, and SLS include references.
