It may add code-focused aids such as syntax highlighting, indentation, bracket matching, snippets, or language-aware navigation, but no single feature is required for something to count as an editor.
What a source-code editor does
At its core, a source-code editor lets you create, read, and modify source files: the human-readable instructions and related text that make up a program. Microsoft describes Visual Studio Code’s editor as combining general text editing with language-aware assistance; Apple describes Xcode’s source editor as a place to edit source files, find issues, and make changes.
A basic text editor can also contain source code. The practical difference is that a source-code editor is designed or configured to make code easier to work with, rather than treating it only as undifferentiated text.
Features that can help with code
Code editors may provide features such as:
- Syntax highlighting: visually distinguishes elements such as keywords, strings, and comments.
- Indentation and bracket matching: helps keep blocks and paired symbols readable.
- Snippets and completion: inserts common patterns or suggests code while you type.
- Search and navigation: helps locate text, symbols, or files in a project.
These are examples, not a universal checklist. Available language-aware features depend on the editor, the programming language, built-in support, and any installed extensions. Microsoft’s documentation describes these capabilities as varying by language and extension support: Core editor features, Language Extensions Overview.

Source-code editor versus IDE
The distinction is mainly about scope, not a rigid naming rule. An editor’s defining job is changing source files. A broader development environment or workbench may put that editor alongside project management and tools to run, build, debug, test, use a terminal, or manage source control. One application can include both editing and these wider workflow tools; that does not make every editor a full IDE.
For example, Visual Studio Code documentation distinguishes the editor from the broader workbench around it, while describing a range of development capabilities in the application. Apple’s Xcode documentation likewise discusses editing source files as one part of working in Xcode. Product features should not be assumed to apply to every code editor.

If you are selecting an editor, start with what you need to do rather than a feature checklist:
- Check that it supports your language, either directly or through extensions.
- Decide whether you only need to edit files or also want tools for running, debugging, testing, and source control.
- Consider how it handles project navigation and any remote or platform-specific workflow you use.
- Try its customization and accessibility options, since comfort and readability affect day-to-day editing.
These are useful comparison points, not a ranking: the right fit depends on the language and workflow. Microsoft’s overview of code editing in Visual Studio describes editor features and their language-dependent behavior: Organize and edit code in Visual Studio.
