1 Section Header🔗ℹ

@section{Section Header}

1.1 Subsection Header🔗ℹ

@subsection{Subsection Header}

1.1.1 Subsubsection header🔗ℹ

@subsubsection{Subsubsection header}

Non-numbered header (doesn’t show up in table of contents)

@subsubsub*section{Non-numbered header (doesn't show up in table of contents)}

2 Documenting code🔗ℹ

Remember that {} converts to a string and [] doesn’t.

2.1 Modules🔗ℹ

(require racket/positronics)

package: base

@defmodule[racket/positronics]

racketblocks require S-expressions and normalize terms (including formatting).

(map (λ (x) (+ 1 x)) '(1 1/2 3 4 5))

@racketblock[
(map
(λ (x)
(+ 1 x)) '(1 2/4
3 4 5))
]

2.2 #langs🔗ℹ

#lang mechanized-loom

@defmodulelang[mechanized-loom]

codeblocks typeset verbatim, allow non-S-expression syntax, and don’t normalize terms.

#lang scribble/manual
@italic{me
ow}

@codeblock|{
#lang scribble/manual
@italic{me
ow}
}|

2.3 Procedures and Forms🔗ℹ

Names defined with defproc, defform, or defthing will be linked to from within rackets.

2.3.1 Procedures🔗ℹ

default is procedure
(proc-name arg ... [#:kwarg kwarg-val]) → result-type
arg : arg/c
kwarg-val : kwarg/c = default

Within this block, things like arg will be typeset to match the definition (but will error within code).

@defproc[#:kind "default is procedure"
         (proc-name [arg arg/c] ...
                    [#:kwarg kwarg-val kwarg/c default])
                    result-type]{
Within this block, things like @racket[arg] will be typeset to match
the definition (but will error within @code{code}).
}

Use defproc* to describe related procedures or procedures with multiple calling cases.

procedure
(multi-proc) → result-type-one
(multi-proc arg) → result-type-two
arg : arg/c

@defproc*[([(multi-proc) result-type-one]
[(multi-proc (arg arg/c)) result-type-two])]

2.4 Syntax🔗ℹ

defform can specify which identifier it’s defining, typeset literals, or include a grammar.

default is syntax
(something-special form-name math)

math = (op num num)

op = plus
| minus

@defform[#:kind "default is syntax"
         #:id form-name
         #:literals (define)
         (something-special form-name math)
         #:grammar
         [(math (op num num))
          (op plus
              minus)]]

Use defform* for multiple forms using the same identifier.

syntax
(define (proc-name arg ...) body ...+)
(define var-name body)

@defform*[((define (proc-name arg ...) body ...+)
(define var-name body))]

2.5 Others🔗ℹ

Use defthing to describe non-procedure identifiers.

value
horse : animal?

Everyone knows what a horse is.

@defthing[horse animal?]{
Everyone knows what a horse is.
}

Use deftech to define vocabulary and tech to link to it.

A technical term is a term that is technical. An example of a technical term is number.

A @deftech{technical term} is a term that is technical.
An example of a @tech{technical term} is
@tech[#:doc '(lib "scribblings/guide/guide.scrbl")]{number}.

3 Formatting🔗ℹ

Margin note (not actually in the margin)

@margin-note{Margin note (not actually in the margin)}

Margin note* (actually in the margin)

@margin-note*{Margin note* (actually in the margin)}

Italic

@italic{Italic}

Bold

@bold{Bold}

woah nesting

@italic{@bold{woah nesting}}

More: subscript, subscript, larger, smaller.

AAAAAAAAAAAA

@larger{AAA@larger{AAA@larger{AAA@larger{AAA}}}}

4 Links🔗ℹ

@link["https://racket-lang.org"]{normal link}

back to top (section link within the same module)

@seclink["scribble-cheatsheet"]{back to top (section link within the same module)}

use #:doc to link somewhere else

@seclink["first-example" #:doc '(lib "scribblings/scribble/scribble.scrbl")]{
use @racket[#:doc] to link somewhere else
}

secref is like seclink but you can’t change the text: A First Example

@secref["first-example" #:doc '(lib "scribblings/scribble/scribble.scrbl")]

tech links to a term defined with deftech: technical term

@tech{technical term}

other-doc links to the top of a document: Scribble: The Racket Documentation Tool

@other-doc['(lib "scribblings/scribble/scribble.scrbl")]
