# Comments {#typoscript-syntax-syntax-comment-blocks}

TypoScript supports single line comments as well as multiline comment blocks.

> [!NOTE]

> Comment handling has been relaxed significantly with the rewritten TypoScript
> parser in TYPO3 v12. The parser is much less picky detecting comments, they
> can be placed almost everywhere since v12, `*/` no longer needs
> to be on a single line, and comments are auto-closed at the end of a single
> text snippets.

`//` and `#` indicate a comment. Everything until the end
of the line will be ignored by the parser. `/*` indicates a multiline
comment start, `*/` stops it.

When using `//`, `#` and `/*` after an assignment
`=`, this is *not* considered a comment, but part of the value! Same is
true for multiline assignments.

Some examples:

**Extension examples, file Configuration/TypoScript/Syntax/Comments/setup.typoscript**

```typoscript
# This is a comment
// This is a comment
/* This is a
multiline comment */

foo < bar // This is a comment
foo < bar /* This is a valid comment, too */

foo > # Another valid comment

foo := addToList(1) # Yes, a comment

[foo = bar] # Many comment. Much wow.

foo (
  # This is NOT a comment but part of the value assignment!
  bar = barValue
) # This is a comment

foo = bar // This is NOT a comment but part of the value assignment!

```
