[ketsig, `^~`, %ktsg](#ktsg)
|
||
|
|
============================
|
||
|
|
|
||
|
|
Compile statically
|
||
|
|
|
||
|
|
`^~` is a natural hoon that tries to execute `p` statically at compile
|
||
|
|
time; if this fails, `p` remains dynamic. `^~` is primarily useful for
|
||
|
|
optimization, when you know that a value is static, or is most likely
|
||
|
|
static, `^~` can simplify the compilation.
|
||
|
|
|
||
|
|
Produces

|
|
--------
|
||
|
|
|
||
|
|
Twig: `[%ktsg p=twig]`
|

|
|
|
||
|
|
Sample
|
||
|
|
------
|
||
|
|
|
||
|
|
`p` is a [twig]().
|
||
|
|
|
||
|
|
Tall form
|
||
|
|
---------
|
||
|
|
|
||
|
|
^~ a
|
||
|
|
|
||
|
|
Wide form
|
||
|
|
---------
|
||
|
|
|
||
|
|
^~(a)
|
||
|
|
|
||
|
|
Irregular form
|
||
|
|
--------------
|
||
|
|
|
||
|
|
None
|
||
|
|
|
||
|
|
Examples
|
||
|
|
--------
|
||
|
|
|
||
|
|
/~zod/try=> (make '|-(42)')
|
||
|
|
[%8 p=[%1 p=[1 42]] q=[%9 p=2 q=[%0 p=1]]]
|
||
|
|
/~zod/try=> (make '^~(|-(42))')
|
||
|
|
[%1 p=42]
|
||
|
|
|
||
|
|
Here we use [`++make`]() to examine the nock generated for a particular
|
||
|
|
computation. We start with a simple kicked trap, `|-` that just
|
||
|
|
generates the static value `42`. When we wrap our `|-` in a `^~` you can
|
||
|
|
see that our compilation is much simpler.
