There are a few different ways to accomplish this, and not every technique is right for every situation, so we did our best to take a look at each way and tested it to ensure it worked. They’re still useful for generating certain types of passwords and code, which might help to keep things secure anyway. This is also a very useful tool when attempting to preform certain security checks, but you’ll want to remember that good crackers can circumvent these simple number generators. Whether you might be writing a D&D campaign or authoring a utility in the powerful bash language, you could usually get away with a single line of code. This is useful for everything from writing certain types of scripts to running tabletop roleplaying adventures. See RFC4122 section 4.1.You can easily generate a random number at the bash prompt, which you can then use to set said number as a variable. 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: Insert a new 'nil' UUID (where all the digits are 0).The other way to run the commands is from the command palette by pressing ( Ctrl+Shift+P or Cmd+Shift+P on Mac), typing UUID and selecting the desired function. ![]() By default, the keyboard binding is Alt+Shift+U. The Insert new UUID function is available from the editor context menu, or as a keyboard binding. This extension supports creating a new version 4 UUID and then either adding it to the current location in the active editor, or placing it on the clipboard. One useful case for this extension is to create UUIDs for configuring new profiles for Windows Terminal. This extension generates Universal Unique Identifier (UUID) values and will either insert them into the current active editor, or place them on the clipboard.
