Solidity by Nomic Foundation

This extension adds language support for Solidity to Visual Studio Code, and provides editor integration for Hardhat projects, and experimental support for Foundry, Truffle and Ape projects. It supports:

• Code completion
• Go to definition, type definition and references
• Symbol renames
• Solidity code formatting
• Inline code validation from compiler errors/warnings for Hardhat projects
• Hover help for variables, function calls, errors, events etc.
• Code actions (quickfixes) suggested from compiler errors/warnings for Hardhat projects
  • Implement missing functions on interface with stubs
  • Constrain mutability by adding view/pure to function signature
  • Meet inheritance requirements by adding virtual/override on function signature
  • Provide accessibility by adding public/private to function signature
  • Specify license identifier and pragma solidity version

Built by the Nomic Foundation. We’re hiring.

Installation

Solidity by Nomic Foundation can be installed by using the Visual Studio Code Marketplace.

Some features (e.g. inline validation, quick fixes) are still experimental and are only enabled within a Hardhat project, this is a limitation that will be lifted with future releases.

Features

Code Completions

The solidity language server autocompletes references to existing symbols (e.g. contract instances, globally available variables and built-in types like arrays) and import directives (i.e. it autocompletes the path to the imported file).

Direct imports (those not starting with ./ or ../) are completed based on suggestions from ./node_modules.

Relative imports pull their suggestions from the file system based on the current solidity file's location.

Natspec documentation completion is also supported

---

Navigation

Move through your codebase with semantic navigation commands:

Go to Definition

Navigates to the definition of an identifier.

Go to Type Definition

Navigates to the type of an identifier.

Go to References

Shows all references of the identifier under the cursor.

---

Renames

Rename the identifier under the cursor and all of its references:

---

Format document

Apply Solidity formatting to the current document, for all the configuration options see Formatting Configuration.

---

Hover

Hovering the cursor over variables, function calls, errors and events will display a popup showing type and signature information:

---

Inline code validation (Diagnostics)

As code is edited, the solc compiler is run over the changes and any warnings or errors are displayed.

---

Code Actions

Code actions, or quickfixes are refactorings suggested to resolve a solc warning or error.

A line with a warning/error that has a code action, will appear with small light bulb against it; clicking the light bulb will provide the option to trigger the code action.

Implement missing functions on interface

A contract that implements an interface, but is missing functions specified in the interface, will get a solidity(3656) error.

The matching code action Add missing functions from interface will determine which functions need to be implemented to satisfy the interface and add them as stubs to the body of the contract.
