Re : help! tikiwiki cut the space indending at the head of every line!
Are you speaking about a wiki syntax feature
Extract of the page WikiSyntax
Block Preformatting: Indent text with any number of spaces to turn it into a monospaced block that still follows other Wiki formatting instructions. It will be indended with the same number of spaces that you used. Note that this mode does not preserve exact spacing and line breaks; use "~pp~ data ~/pp~" for that.
