Comments are denoted by the @# (at-pound) symbols. TPT only supports to end-of-line comments. I.e. everything on the line following @# is a part of the comment.
Hello World! @# This is the Hello World Comment.
In the above example, everything after Hello World! will be ignored by the TPT parser, including the whitespace. Comments affect whitespace depending on use. All whitespace immediately preceeding a comment is ignored. In the case of a full line comment,
@# This is a full line comment @# This is not
the entire line, including carriage returns, is ignored. In order to be classified as a full line comment, @# must be the very first characters on the line. Preceding the @# with whitespace will only cause the whitespace and comment to be ignored. This is useful if you need to insert a certain number of blank lines into a template.
@# Insert some blank lines @# blank line 1 @# blank line 2 @# blank line 3 @# blank line 4 @# blank line 5
