Atom: An atom is an item in difftastic's syntax tree structure that has no children. It represents things like literals, variable names, and comments. See also 'list'.
Delimiter: A paired piece of syntax. A list has an open delimiter
and a close delimiter, such as
]. Delimiters may not be
end) and may be empty strings (e.g. infix
syntax converted to difftastic's syntax tree).
LHS: Left-hand side. Difftastic compares two items, and LHS refers to the first item. See also 'RHS'.
List: A list is an item in difftastic's syntax tree structure that has an open delimiter, children, and a close delimiter. It represents things like expressions and function definitions. See also 'atom'.
Novel: An addition or a removal. Syntax is novel if it occurs in only one of the two items being compared.
RHS: Right-hand side. Difftastic compares two items, and RHS refers to the second item. See also 'LHS'.
Root: A syntax tree without a parent node. Roots represent top-level definitions in the file being diffed.
Syntax node: An item in difftastic's syntax tree structure. Either an atom or a list.
Token: A small piece of syntax tracked by difftastic (e.g.
]), for highlighting and aligned display. This is
either an atom or a non-empty delimiter.
