hash-table-key-exists-p v1.0

Does key exist in hash-table?

Provides: hash-table-key-exists-p

hash-tables orthogonality

Source Code

dohash v1.0

Iterate over the hash table table, executing body, with key and value bound to the keys and values of the hash table respectively. Return result from the iteration form.

Provides: dohash

hash-tables orthogonality

Source Code

copy-cons v1.0

Copy the cons cell c.

Provides: copy-cons

conses orthogonality

Source Code

copy-hash-table v1.0

Returns a copy of hash table table, with the same keys and values as the table. The copy has the same properties as the original, unless overridden by the keyword arguments.

Before each of the original values is set into the new hash-table, key is invoked on the value. As key defaults to cl:identity, a shallow copy is returned by default.

Provides: copy-hash-table

xor v1.0

Evaluates its arguments one at a time, from left to right. If more then one argument evaluates to a true value no further datums are evaluated, and nil is returned as both primary and secondary value. If exactly one argument evaluates to true, its value is returned as the primary value after all the arguments have been evaluated, and t is returned as the secondary value. If no arguments evaluate to true nil is retuned as primary, and t as secondary value.

Provides: xor
Requires: with-gensyms

multiple-value-prog2 v1.0

Evaluates first-form, then second-form, and then forms. Yields as its value all the value returned by second-form.

Provides: multiple-value-prog2

disjoin v1.0

Returns a function that applies each of predicate and more-predicate functions in turn to its arguments, returning the primary value of the first predicate that returns true, without calling the remaining predicates. If none of the predicates returns true, nil is returned.

Provides: disjoin
Requires: ensure-function

alexandria functional orthogonality

Source Code

conjoin v1.0

Returns a function that applies each of predicate and more-predicate functions in turn to its arguments, returning nil if any of the predicates returns false, without calling the remaining predicates. If none of the predicates returns false, returns the primary value of the last predicate.

Provides: conjoin

compose v1.0

Returns a function composed of function and more-functions that applies its ; arguments to to each in turn, starting from the rightmost of more-functions, and then calling the next one with the primary value of the last.

Provides: compose

copy-array v1.0

Returns an undisplaced copy of array, with same fill-pointer and adjustability (if any) as the original, unless overridden by the keyword arguments.

proper-list-p v1.0

Returns true if object is a proper list.

Provides: proper-list-p
