About .sublime-completions Files
SUBLIME-COMPLETIONS files are text-based configuration files that supply auto-completion suggestions for the Sublime Text editor.
They use a JSON structure that permits comments. This is why the MIME type is set to text/javascript (a format akin to JSON with Comments).
- Primary use: Define code snippet and auto-complete options that trigger as you type.
- Format details: Structured as JSON with allowed inline comments to explain or mark sections.
- MIME type: The text/javascript type indicates that the file is text-based and leverages a JavaScript-style syntax.
- Editing: Primarily used by Sublime Text, but you can also open or modify it using any text editor.
They are especially useful for developers looking to streamline repetitive coding tasks with predefined completions.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .sublime-completions file?
A .sublime-completions file is a configuration file used by the Sublime Text code editor to define custom auto-complete suggestions. It allows developers to create lists of triggers and corresponding code snippets that appear automatically while typing, speeding up the development process.
How do I open and edit a .sublime-completions file?
Since these are plain text files, you can open them with any text editor, such as Notepad, TextEdit, or VS Code. However, the best way to edit them is within Sublime Text itself, as it provides specific syntax highlighting for the JSON structure used inside the file.
Where should I save my .sublime-completions file?
To make the completions active, you must save the file in the Packages/User directory within your Sublime Text installation. You can easily locate this folder by opening Sublime Text and selecting Preferences > Browse Packages... from the menu.
Why is the MIME type for this file listed as text/javascript?
Although the file follows a JSON structure, valid JSON does not allow comments. These files use a relaxed syntax that permits comments, technically making them valid JavaScript objects; therefore, they are often associated with text/javascript rather than strict application/json.
Why are my custom completions not appearing while I type?
This is usually due to an incorrect scope selector within the file or a syntax error like a trailing comma. Ensure the scope matches the file type you are working in (e.g., source.python for Python files) and validate your syntax against standard JSON rules.
What is the basic structure of a .sublime-completions file?
The file contains a JSON object with a scope key (defining where the completions trigger) and a completions array. Inside the array, you can list simple strings or objects containing trigger (what you type) and contents (what is inserted) keys.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
