(boot-server opts Main & args)

boot-single clj macro

(boot-single opts Main & args)

call clj macro

(call F & args)

capture-fn clj

(capture-fn)

Captures variability of a function under a stable identity. Return a proxy to the captured function. Use case: prevent unmount and remount when a cc/fn argument updates due to an inner variable dependency.

check-electric clj macro

(check-electric fn form)

client clj macro

(client & body)

ctor clj macro

(ctor expr)

cursor clj macro

(cursor bindings & body)

CyclicToken clj

(CyclicToken v)

(CyclicToken v on?)

(defn nm & fdecl)

dget clj

(dget v)

diff-by clj macro

(diff-by f xs)

Syntax :

(diff-by kf xs)

Stabilizes successive states of collection xs with function kf. Returns each item as a table.

Dispatch clj

(Dispatch eF static args)

drain clj macro

(drain expr)

Syntax :

(drain expr)

Samples and discards expr synchronously with changes. Returns nothing.

fn clj macro

(fn & args)

for clj macro

(for bindings & body)

Syntax :

(for [sym1 table1
      sym2 table2
      ,,,  ,,,
      symN tableN]
  & body)

For each tuple in the cartesian product of table1 table2 ,,, tableN, calls body in an implicit do with symbols sym1 sym2 ,,, symN bound to the singleton tables for this tuple. Returns the concatenation of all body results.

for-by clj macro

(for-by kf bindings & body)

Syntax :

(for-by kf [sym1 coll1
            sym2 coll2
            ,,,  ,,,
            symN collN]
  & body)

Stabilizes successives states of coll1 coll2 ,,, collN with function kf. For each tuple in the cartesian product of resulting tables, calls body in an implicit do with symbols sym1 sym2 ,,, symN bound to the singleton tables for this tuple. Returns the concatenation of all body results as a single vector.

frame clj macro

(frame)

http-request clj

Bound to the HTTP request of the page in which the current Electric program is running.

input clj macro

(input & flows)

Syntax :

(input cf)

Returns the current state of current continuous flow cf.

join clj macro

(join flow)

Syntax :

(join incseq)

Returns the successive states of items described by incseq.

Latchable clj

(Latchable v)

letfn clj macro

(letfn bs & body)

mount-point clj macro

(mount-point)

Returns a new mount point instance. A mount point can be :

• mutated as a key-value store via the KVS protocol. Keys must be tags generated by the same electric application.
• watched as an incremental sequence. Values will be sorted according to the relative ordering of tags.

(ns-qualify sym)

Offload clj

(Offload f!)

(Offload f! executor)

on-unmount clj macro

(on-unmount f)

Run clojure(script) thunk f during unmount.

Standard electric code runs on mount, therefore there is no on-mount.

(on-unmount* f)

OnUnmount clj

(OnUnmount f)

Partial clj

(Partial F)

(Partial F arg1)

(Partial F arg1 arg2)

(Partial F arg1 arg2 arg3)

(Partial F arg1 arg2 arg3 & more)

Takes an Electric function F and fewer than the normal arguments to F, and returns a e/fn that takes a variable number of additional args. When called, the returned function calls F with args + additional args.

pure clj macro

(pure expr)

Syntax :

(pure table)

Returns the incremental sequence describing table.

server clj macro

(server & body)
