Tile construction
|
||
|
-----------------
|
||
|
|
||
|
The `$` runes construct [`++tile`]()s. [`++tile`]()s are one of our
|
||
|
primary building blocks in hoon, they define how we reduce our ASTs into
|
||
|
well typed nouns that nock can compute. You can think of a [`++tile`]()
|
||
|
sort of like a typeclass in Haskell.

#### Forks
|
||
|
|
||
|
##### [`++tile`]()s that can be one of multiple cases.
|
||
|
|
||
|
[`$?`]() Non-empty list of cases.
|
||
|
|
||
|
[`$|`]() Fork between atom and cell.
|
||
|
|
||
|
[`$&`]() Fork between cells whose head is a cell and cells whose head is
|
||
|
an atom.

#### Tuples
|

|
|
||
|
[`$:`]() Unlabelled arrays.
|
||
|
|
||
|
[`$=`]() Tuple with [`++face`]()s.

#### Reductions
|
||
|
|
||
|
##### Important convenience methods for working with tiles, and are very broadly used.
