In detail

Three small tools you'd otherwise search for

No website to open and nothing to paste into a form. The result is made on your computer and shows at the top of the palette.

Seven case styles from one line

Type :tx and your text to see it in UPPER CASE, lower case, Title Case, camelCase, PascalCase, snake_case and kebab-case, one row each. Move to the style you want and press ↵ to copy it.

  • Names already in camelCase are split into words: :tx userProfileId gives user_profile_id.
  • Spaces, dashes and other symbols count as word breaks.

A password with the length and characters you need

:pwd makes a 16-character password from letters, digits and symbols. Add a length from 1 to 128, like :pwd 24. Add a letter after the length to limit the characters: a for letters and digits, c for letters only, n for digits only.

  • Made with the browser’s crypto.getRandomValues, not Math.random.
  • Not happy with it? Type a space and delete it, and you get a new one.
  • Enter copies it and the toast says Password copied.

A new UUID whenever you need one

Type :uuid and a random version 4 UUID shows at the top, made with the browser’s crypto.randomUUID. Press ↵ to copy it into a test, a config file or a database row.

  • You get a different UUID every time you type it.
  • It’s lowercase with dashes, the standard 36-character form.

More reasons to keep these in the palette

  • Never saved

    Passwords and UUIDs are made on your computer when you type the command. TabCmdr doesn’t store them or send them anywhere.

  • No mouse needed

    Arrow keys move between the seven case styles, and ↵ copies the one you’re on.

  • Clear copy messages

    The toast tells you what happened: Copied, Password copied or UUID copied.

  • On any page

    Rename a variable while you read docs or review a pull request, without leaving the tab.

  • Colors and number bases

    #f0013d to rgb and 0xff to decimal are answered in the same box.

  • Math and px to rem

    Sums and conversions like 24px to rem work without a token.
