Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

Functions, Macros, and Special Forms

• difference

  Function v1.0

  (difference s1)
  (difference s1 s2)
  (difference s1 s2 & sets)
  

  Return a set that is the first set without elements of the remaining sets

  source

• index

  Function v1.0

  (index xrel ks)
  

  Returns a map of the distinct values of ks in the xrel mapped to a
  set of the maps in xrel with the corresponding values of ks.

  source

• intersection

  Function v1.0

  (intersection s1)
  (intersection s1 s2)
  (intersection s1 s2 & sets)
  

  Return a set that is the intersection of the input sets

  source

• join

  Function v1.0

  (join xrel yrel)
  (join xrel yrel km)
  

  When passed 2 rels, returns the rel corresponding to the natural
  join. When passed an additional keymap, joins on the corresponding
  keys.

  source

• map-invert

  Function v1.0

  (map-invert m)
  

  Returns the map with the vals mapped to the keys.

  source

• project

  Function v1.0

  (project xrel ks)
  

  Returns a rel of the elements of xrel with only the keys in ks

  source

• rename

  Function v1.0

  (rename xrel kmap)
  

  Returns a rel of the maps in xrel with the keys in kmap renamed to the vals in kmap

  source

• rename-keys

  Function v1.0

  (rename-keys map kmap)
  

  Returns the map with the keys in kmap renamed to the vals in kmap

  source

• select

  Function v1.0

  (select pred xset)
  

  Returns a set of the elements for which pred is true

  source

• subset?

  Function v1.0

  (subset? set1 set2)
  

  Is set1 a subset of set2?

  source

• superset?

  Function v1.0

  (superset? set1 set2)
  

  Is set1 a superset of set2?

  source

• union

  Function v1.0

  (union)
  (union s1)
  (union s1 s2)
  (union s1 s2 & sets)
  

  Return a set that is the union of the input sets
