GUIDs for identifiers and an ID collision would break the system, then you For example, if you have an API where you can create entities with If ID conflicts can break your system or create securityĬoncerns then GUIDs are not for you unless you can complete control over their Other properly generated unique identifiers. Values themselves are 128 bits of data that are guaranteed to be unique among For our purposes we can consider them synonyms. Guaranteed to be unique of we combine values from across the galaxy, the realĭifferentiation is that GUID refers to various implementations of the UUID Although the names imply that a GUID is not UUID/GUID: UUID stands for Universally Unique Identifier and GUID standsįor Globally Unique Identifier. Windows, Linux, Mac OS, Android, and iOS. The implementation should alsoĪvoid unnecessary abstraction so that there are fewer lines of code and anyoneĬan quickly read the implementation to see clearly what it is doing.Ĭross platform: Works on all major operating systems. It should also be trivial to source embed the module Minimalist: The amount of code will have a negligible affect on compile Will probably not update the snippets in this article. See RFC4122 section 4.1.Over time I will like make updates and bug fixes to the git repository, but I This extension can also be used to produce a 'nil' UUID, one where all the values are zero. This cannot guarantee uniqueness to the same degree as something tied to hardware identifiers such as MAC address, but it is statistically unlikely that any two UUIDs would be identical. Version 4 UUIDs are generated with random numbers as generated by VS Code and modified by a portion of the current timestamp to add another random element. This extension generates UUIDs that are version 4, variation 1 according to the specification RFC4122 section 4.4. Whether the generated UUID should be automatically wrapped with quotes or braces. When the UUID is inserted into the text, this setting controls whether the pasted value is marked as selected ( true) or whether the selection is cleared ( false) Whether the hex digits are forced to uppercase ( true) or lowercase ( false) ![]() Whether the Insert new UUID function is available from the editor context menu See the release notes for more information. The extension can also generate a nil UUID, where all the digits are 0. ![]() The generated UUIDs are type 4, variation 1, which means unique based on random numbers. It will insert the UUID at the location of the caret in the current active editor, replace any existing text selection if there is one, and generate multiple UUIDs and insert them all when a multi-cursor selection is active. This extension works as expected when inserting a new UUID into the active text editor. Through configuration settings, it is possible to wrap the created UUID with braces or quotes when it is created, for example:
