1.1.1 Subsubsection header🔗ℹ
Non-numbered header (doesn’t show up in table of contents)
2 Documenting code🔗ℹ
Remember that {} converts to a string and [] doesn’t.
racketblocks require S-expressions
and normalize terms (including formatting).
(map (λ (x) (+ 1 x)) '(1 1/2 3 4 5))
codeblocks typeset verbatim, allow non-S-expression syntax,
and don’t normalize terms.

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
(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.
(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])] |
defform can specify which identifier it’s defining,
typeset literals, or include a grammar.
(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.
(define (proc-name arg ...) body ...+)
|
| (define var-name body) |
Use defthing to describe non-procedure identifiers.
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 @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}. |
