Miscellaneous operators

Operators that no other group holds.

Every program can use these operators. No import is necessary.

Operator	Arguments	Gives
`?`	condition: boolean, left: T, right: T	`T`
`+`	left: double, right: string	`string`
`+`	left: int, right: string	`string`

`buffer_get`	buf: buffer, offset: int	`int`
`buffer_length`	buf: buffer	`int`

Target support marks

Own template
Default template
No template

The operator works for a target with an own template and for a target with the default template. The default template is the * entry of the definition: it writes the same code for every target that has no template of its own. A target with no template writes no code, and a program that uses the operator does not compile for that target.

`?`

(? condition left right) → T

?(condition: boolean, left: T, right: T)

`charAt`

(charAt text position) → char

charAt(text: charbuffer, position: int)

ONE BYTE, 0..255, at that index. Not one character: a character outside ASCII is two, three or four of these, so this is the operator to reach for when the subject really is bytes and the wrong one for walking text. See the block above the charbuffer overloads.

`substring`

(substring text start end) → string

substring(text: charbuffer, start: int, end: int)

The TEXT that this range of bytes is the UTF-8 of. One of the three places the line between bytes and text is crossed, so it decodes: a range that cuts a character in half gives a replacement character, which is what makes a one-byte-at-a-time copy of a buffer back into a string wrong. See the block above.

`to_string`

(to_string text) → string

to_string(text: charbuffer)

The TEXT these bytes are the UTF-8 of -- the other direction of `to_charbuffer`. Bytes that are not valid UTF-8 come back as replacement characters; a buffer holding a PNG has no text in it and this operator has nothing to say about one.
