[cencol, `%:`, %cncl](#cncl)
|
||
|
|
============================
|
||
|
|
|
||
|
|
Slam, one argument
|
||
|
|
|
||
|
|
`%:` is a synthetic rune that that [pull]()s [`$`]() from the [door]()
|
||
|
|
`p` with its sample set to `q`. `%:` in the most common case simply
|
||
|
|
[slam]()s `p` with `q`, similar to a function call with one argument.
|
||
|
|
Unlike its close relative `%-`, `%:` is designed for [gate]()s who take
|
||
|
|
a single value as their sample.
|
||
|
|
|
||
|
|
Produces
|
||
|
|
--------
|
||
|
|
|
||
|
|
Twig: `[%cncl p=twig q=twig]`
|
||
|
|
|
||
|
|
Sample
|
||
|
|
------
|
||
|
|
|
||
|
|
`p` is a [twig](), most commonly a [gate]() `q` is a [twig]()
|
||
|
|
|
||
|
|
Tall form
|
||
|
|
---------
|
||
|
|
|
||
|
|
%: p
|
||
|
|
q
|
||
|
|
|
||
|
|
Wide form
|
||
|
|
---------
|
||
|
|
|
||
|
|
%:(p q)
|
||
|
|
|
||
|
|
Irregular form

Examples
|
||
|
|
--------
|
||
|
|
|
||
|
|
/~zod/try=> %:(dec 42)
|
||
|
|
41
|
||
|
|
|
||
|
|
Here we use `%:` in its most straightforward form, to call an arm that
|
||
|
|
takes one argument.
|
||
|
|
|
||
|
|
/~zod/try=> %: dec
|
||
|
|
%+ add 2
|
||
|
|
%+ mul 2 20
|
||
|
|
41
|
||
|
|
|
||
|
|
Here we call [`++dec`]() with the sum of `2` and the product of `2` and
|
||
|
|
`20` using `%:`. As you can see, `%:` is most useful for code
|
||
|
|
organization, when you need to compute intermediate products for your
|
||
|
|
final result
