A Good Editor Helps a Lot
You can write Mojo in any text editor, but an editor that understands the language makes learning far smoother. Let's set one up. ✨
VS Code Is the Easy Path
Modular ships first-class support for VS Code. It is the simplest editor to get a great Mojo experience right away.
Install the Mojo Extension
Open the Extensions panel and search for Mojo. Install Modular's official extension to unlock language features.
Syntax Highlighting
The first thing you notice is color. Syntax highlighting paints keywords, strings, and types so code is easy to scan.
Code Completion
As you type, the extension suggests names and members. This autocomplete speeds you up and helps you discover the API.
Inline Error Hints
Mistakes get underlined before you ever run the file. These diagnostics catch typos and type errors as you write.
Hover for Docs
Rest your cursor on a symbol to see its type and docs. This hover info means fewer trips to a separate reference.
Pick the Right Toolchain
The extension needs to find Mojo. Opening your magic project folder lets it locate the toolchain from your environment.
Format on Save
Turn on format-on-save so your code stays tidy automatically. Consistent formatting keeps files clean without manual effort.
Other Editors Work Too
Prefer Neovim or another editor? Many connect to Mojo's language server directly, though setup takes a few more steps.
Run Right from the Editor
VS Code adds a run button for Mojo files, so you can execute a program without leaving the editor or typing a command.
Quick Check
Recall what the official Mojo extension gives you beyond plain text.
Recap
You added the Mojo extension for highlighting, completion, and inline errors, opened your project so it finds the toolchain. Ready to code! 🎯
