[centar, `%*`, %cntr](#cntr)
|
|
============================
|
|
|
|
Pull with changes
|
|
|
|
`%*` is a synthetic rune that [pull]()s the wing `p` from a [door]() `q`
|
|
with changes `r`, terminated by `==`. `%*` is used to specify changes in
|
|
the context of a wing when it is pulled.

Sample
|
|
------
|
|
|
|
`p` is a [++wing](). `q` is a [++twig](). `r` is a [++tram]().

%*(p q p.i.r q.i.r, p.i.t.r q.i.t.r)

Examples
|
|
--------
|
|
|
|
/~zod/try=> =a 42
|
|
new var %a
|
|
/~zod/try=> =b |%
|
|
++ mult (mul 2 a)
|
|
--
|
|
new var %b
|
|
/~zod/try=> mult.b
|
|
84
|
|
/~zod/try=> %*(mult b a 2)
|
|
4
|
|
|
|
Here we add a variable `a` to our context, and a door `b` with a wing
|
|
`++mult`that depends on `a`. Calling `++mult` produces `84`, and we can
|
|
use `%*` to replace `a` in the context of `mult.b` with `2` to simply
|
|
produce `4`.
