Expand description

Token classes.

Variants§

Word(RawWord)

A structured word.

Pipe

|.

Semicolon

;.

DoubleSemicolon

;;, which ends one case clause.

Newline

A line break.

AndAnd

&&.

OrOr

||.

Ampersand

&. Kept as a token so the parser can hard-fail on backgrounding.

LeftParen

(.

RightParen

).

LeftBrace

{ used as a reserved word.

RightBrace

} used as a reserved word.

Great

>.

GreatGreat

>>.

Less

<. Kept so the parser can explain that there are no files to read.

HereDoc(RawWord)

A <<DELIM here-document, with its body already collected off the following lines.

LessParen

<(. Kept so the parser can reject process substitution by name.
