Core construction
|
||
|
-----------------
|
||
|
|
||
|
The `|` runes construct [core]()s. In the broadest case you can think of
|
||
|
a core as similar to an object with named properties that can contain
|
||
|
either functions or data.
|
||
|
|
||
|
The `|` runes accept an associative array of names ([++term]()) to
|
||
|
([++foot]()), each pair of which are called an [++arm](), producing one
|
||
|
of the three basic categories of core.
|
||
|
|
||
|

|
||
|
|
||
|
#### The natural, generic core:
|
||
|
|
||
|
[`|%`]() Generic core, with [++arms] generally containing [++twig]()s
|
||
|
|
||
|
<hr></hr>
|
||
|
|
||
|
#### Doors, generic core with a sample:
|
||
|
|
||
|
##### Gates:
|
||
|
|
||
|
Cores with one arm [`$`], the empty name and which takes a sample
|
||
|
`p`. The closest thing in Hoon to a function.
|
||
|
|
||
|
[`|=`]() [`dry`]() gate, where the [sample]() is typechecked at compile
|
||
|
time. [`|*`]() [`wet`]() gate, where the sample is typechecked at
|
||
|
runtime against its product type.
|
||
|
|
||
|
##### Traps:
|
||
|
|
||
|
Traps reduce to a `|%` with one arm `$`, the empty name. A trap is just
|
||
|
some computation that has been put inside of a wrapper so that it may be
|
||
|
passed around.
|
||
|
|
||
|
[`|.`]() Generic trap. [`|-`]() Trap automatically [kick]ed (called)
|
||
|
after construction.
