of the platform. Indentation Nim's standard grammar describes an indentation sensitive language. This means that all the control structures are recognized by indentation. Indentation consists only of tabulators are not allowed. The indentation handling is implemented as follows: The lexer annotates the following token with the preceding number of spaces; indentation is not a separate token. This trick with only 1 token of lookahead. The parser uses a stack of indentation levels: the stack consists of integers counting the spaces. The indentation information is queried at strategic places in the parser

that these lines start with two additional spaces compared to the previous line. This form of indentation is used in Nim (and Python) to indicate blocks. Blocks are grouped statements. The complete while column. However, the two lines after the while keyword should start with two spaces. This strict indentation is used in Nim and some other programming languages, such as Python and Haskell, to structure compiler — instead, blocks have to be enclosed in curly braces {}. Note that you have to do the indentation really with spaces, as Nim does not accept tabulator characters in its source files. Also, be
