# Whitespace and indentation [Syntax and values](README.md) Spaces indent blocks. Tabs are not valid Pliro whitespace and produce a diagnostic. An indented block may use any positive increase in spaces, but a later dedent must return exactly to an earlier indentation width. The formatter standardizes every block level to four spaces. ```pliro # language: en let score = 12 if score >= 10: say "High score" say score else: say "Keep trying" ``` Blank lines and comment-only lines do not open, close, or alter a block. Outside indentation, ASCII form-feed and vertical-tab characters are currently ignored as intra-line separators; they do not contribute indentation width. Other [Unicode](../concepts/unicode.md) space characters are not generic Pliro whitespace. Ordinary source should use ASCII spaces and line breaks. Inside matching parentheses, brackets, or braces, physical newlines and leading indentation are continuation trivia: ```pliro # language: en let colors = [ "red", "green", "blue", ] let player = { "name": "Pip", "score": 100, } drawText( 320, 20, player.name, 24, "#ffffff", "sans", "center", ) ``` Pliro has no semicolon statement separator. Put separate statements on separate logical lines. ## Related entries [Syntax and values](README.md) · [Built-ins](../builtins/README.md) · [Programming guides](../guides/README.md)
