Functions

void cadabra::do_list (const Ex &tr, Ex::iterator it, std::function< bool(Ex::iterator)> f)
 Apply a function on every element of a list, or if the iterator 'it' does not point to a list, only on that single element. More...
 
int cadabra::list_size (const Ex &tr, Ex::iterator it)
 For lists as defined above for 'do_list', return their size (in case you really need to know the size before iterating over the elements). More...
 
Ex::iterator cadabra::do_subtree (const Ex &tr, Ex::iterator it, std::function< Ex::iterator(Ex::iterator)> f)
 Apply a function on every node in the tree at and below the given node, depth-first. More...
 
Ex::iterator cadabra::find_in_list (const Ex &tr, Ex::iterator it, std::function< Ex::iterator(Ex::iterator)> f)
 Returns an iterator to the first element for which 'f' does not return tr.end(). More...
 
Ex::iterator cadabra::find_in_subtree (const Ex &tr, Ex::iterator it, std::function< bool(Ex::iterator)> f, bool including_head=true)
 Returns an iterator to the first element for which 'f' returns 'true', or 'tr.end()'. More...
 
Ex cadabra::make_list (Ex el)
 Ensure that the tree is a list, even if it contains only a single element. More...
