# Calls Before Declarations

-   `fn1()``fn2()`
-   `fn3(true)`
-   `fn4(2.0, 3.1)`
-   `fn3(n: false)`
-   `fn4(b: 4, a: 5)`

# Declarations

All literate declarations goes in code blocks that should be printed on
`--verbose`.

Minimal (Lua by default):

    ---
    id: fn1
    ...
    1 + 2 + 3

With scape:

    ---
    id: fn2
    ...
    "\#x"

With arg:

    ---
    id: fn3
    args:
      n: str
    ...
    #n == #n

With lang and args:

    ---
    id: fn4
    lang: fennel
    args:
      a: 1
      b: 2
    ...
    (* #a #b)

With cmd (ignores lang):

    ---
    id: fn5
    cmd: python -E -X utf8
    args:
      n: 2
    ...
    #n + #n

With shift:

    ---
    id: fn6
    shift: true
    ...
    "The literate block is shifted by its eval result."

With wipe:

    ---
    id: fn7
    wipe: true
    ...
    "This evals but it is wipe from doc."

With typed:

    ---
    id: fn4
    typed: true
    args:
      a: 1
      b: 2
    ...
    #a * #b

With link and alt:

    ---
    id: fn8
    lang: graphviz
    link: ./graph.png
    alt: A graph.
    ...
    digraph G {
      a -> b;
      b -> c
      c -> a;
    }

With img and alt:

    ---
    id: fn9
    lang: graphviz
    img: ./graph.png
    alt: A graph.
    ...
    digraph G {
      a -> b;
      b -> c
      c -> a;
    }

With dump and quote:

    ---
    id: fn10
    dump: ./dump.txt
    quote: true
    ...
    This code is saved into './dump.txt' because of 'dump'.
    This code is not evaluated because 'quote' is true.

With inner function:

    ---
    id: fn11
    args:
      x: 2
    ...
    `fn1()` * x

With inner function with args:

    ---
    id: fn12
    args:
      y: 1
      z: 2
    ...
    #y + `fn4(3, 4)` + #z

With inner inner function:

    ---
    id: fn13
    args:
      a: 1
    ...
    #a + `fn4(#a, `fn1()`)`

# Code Blocks That Are Not Declarations

Always ignored:

    ---
    echo "Ignore me!"
