String Endings (most useful)

this will match all strings in your code that ends with any of Style, ClassName and ClassNames. i.e const mainStyle = "...", const mainClassName = "..." and const classNames = "..."

"tailwindCSS.experimental.classRegex": [
  ["\\b\\w*Style\\b\\s*=\\s*[\"'`]([^\"'`]*)[\"'`]"],
  ["\\b\\w*ClassName\\b\\s*=\\s*[\"'`]([^\"'`]*)[\"'`]"],
  ["\\b\\w*ClassNames\\b\\s*=\\s*[\"'`]([^\"'`]*)[\"'`]"],
],

clsx

clsx

"tailwindCSS.experimental.classRegex": [
  ["clsx\\(.*?\\)(?!\\])", "(?:'|\"|`)([^\"'`]*)(?:'|\"|`)"]
]

# Take note of the outer square brackets!

clsx('p-4', 'text-center');

TypeScript or JavaScript variables, strings or arrays with keyword

Captures Tailwind classes based on the following patterns:

• variables ending with a "Styles" suffix and with or without TS types.
• classes within single quotes, double quotes, or backticks
• classes within strings or arrays

Edit Styles keyword to target different variable names/suffixes

"tailwindCSS.experimental.classRegex": [
  ["Styles\\s*(?::\\s*[^=]+)?\\s*=\\s*([^;]*);", "['\"`]([^'\"`]*)['\"`]"]
]

Examples:

const variableStyles: (string | undefined)[] = [
  className,
  showCaret ? 'pr-1' : '',
  icon ? 'px-1.5 py-0.5' : 'px-3 py-1',
];

const baseStyles = `items-center flex p-5 mx-2 my-1`;

EVERYWHERE!!!

For those who are just looking for a quick fix and want to enable tailwind intellisense everywhere.

"tailwindCSS.experimental.classRegex": [
  "([a-zA-Z0-9\\-:]+)"
]

pt-1
"pt-1"
const x = "pt-1"
// Will literally trigger everywhere

Note: The intellisense for tailwind will show up everytime you type a letter, so it might get annoying. Only use this if you are 100% sure!

Create an issue if you are trying to find a regex to match a certain pattern
