The iexpr library contains a procedure for parsing of I-expressions as described in SRFI-49.
- (parse LOC STRING-OR-PORT) => TREE procedure
Parses I-expression text and returns a tree object with the parsed content. LOC is a symbol that indicates the name of the current entity being parsed. It is used for error reporting.
- (tree-empty? TREE) => BOOL procedure
Returns #t is the given tree object is empty, #f otherwise.
- (tree-level TREE) => INTEGER procedure
Returns the indentation level of the text contained in the given tree node.
- (tree-child TREE) => TREE procedure
Returns the first child of the given tree node.
- (tree-sibling TREE) => TREE procedure
Returns the first sibling of the given tree node.
- (tree->list TREE) => LIST procedure
Converts the given tree to a list structure.
