Typographic Rules

The Dictionary documentation uses the following typographic conventions:
Definition terms are printed in fixed-width face:
```
cents->scaler
```
Literals and programming code are printed in fixed-width face:
```
(list (note 60)(rhythm 'h))
```
Variables and metavariables (names that stand for pieces of code) are printed in italic face:
```
number
```
Terms separated by | are exclusive choices where exactly one must apply:
```
number | boolean
```
Braces { } and brackets [ ] are sometimes used to associate or group the enclosed terms and are not part of actual code.
- Braces group the enclosed terms into a single entity. Thus:
```
{number | boolean}
```
  describes single value that is either a number or a boolean.
- Brackets make the enclosed term optional. An optional term may appear at most one time. For example, in the following definition:
```
(odds prob [trueval] [falseval])
```
  prob is a required argument that may be followed by up to two optional values. Thus, each of the following calls is correct:
```
(odds .5)
(odds 1 'win)
(odds 0.2 "Yup" "Nope")
```
A star * after a brace means that the enclosed terms may be specified zero or more times. For example:
```
(new class {keyword value}*)
```
means that any number of keyword and value pairs, including none, may follow the required class argument. Each of the following calls is correct:
```
(new midi)
(new midi :time 10)
(new midi :keynum 22 :duration 3)
```
A plus + after a brace means that the enclosed terms may be specified one or more times.
A sequence of three dots means the rest of the arguments, no matter how many. For example:
```
(pick arg ...)
```
means that any number of additional values, including none, may follow arg.
Evaluation is indicated using the right arrow:
```
⇒
```
Syntax highlighting distinguishes important syntactic units:

keyword string special comment

:music "Hello, world" loop ;; bug!
