 Import

The public interface to a native AST component of the form 'import (alias (symbol := symbol)+)? (exclude symbol (, symbol)*)?' Examples: 'import o' => (import (symbol o) (table) (table)) 'import o alias foo := bar' => (import (symbol o) (table (table (symbol foo) (symbol bar))) (table)) 'import o exclude foo, bar:' => (import (symbol o) (table) (table (symbol foo) (symbol bar:))) 'import o alias a: := b, c := d: exclude e, f => (import (symbol o) (table (table (sym a:) (sym b)) (table (sym c) (sym d:))) (table (sym e) (sym f)))

Method Detail

importedObjectExpression

Expression importedObjectExpression()

Example: `{ import o }.statements[1].importedObjectExpression == `o

Returns:

the expression that should evaluate to the object to import.

aliasedSymbols

Expression aliasedSymbols()

Example: `{ import o alias foo := bar }.statements[1].aliasedSymbols == `[[foo, bar]]

Returns:

a table of pairs (tables of size two) of symbols that defines the mapping of symbols to alias.

excludedSymbols

Expression excludedSymbols()

Example: `{ import o exclude a, b }.statements[1].excludedSymbols == `[a,b]

Returns:

a table of symbols that represent the symbols to be excluded from the imported object.
