procedure
(identifier->symbol id) → symbol?
id : identifier?
Convert an identifier to a symbol.
Examples:
> (identifier->symbol #'revise) 'revise
> (identifier->symbol #'arc+) 'arc+
> (identifier->symbol #'| - |) '| - |
procedure
(symbol->identifier sym [srcloc]) → identifier?
sym : symbol? srcloc : (or/c #f syntax? srcloc?) = #f
Convert a symbol to an identifier.
Example:
> (symbol->identifier 'abc) #<syntax abc>
When srcloc is provided, the srcloc of the result will follow the given.
Examples:
> (define srcloc #'id) > (symbol->identifier 'abc srcloc) #<syntax:eval:5:0 abc>
procedure
(identifier->string id) → string?
id : identifier?
Convert an identifier to a string.
Examples:
> (identifier->string #'abc) "abc"
> (identifier->string #'+-*/@~*&%$) "+-*/@~*&%$"
> (identifier->string #'||) ""
> (identifier->string #'| - |) " - "
procedure
(string->identifier str [srcloc]) → identifier?
str : string? srcloc : (or/c #f syntax? srcloc?) = #f
Convert a string to an identifier.
Example:
> (string->identifier "abc") #<syntax abc>
When srcloc is provided, the srcloc of the result will follow the given.
Examples:
> (define srcloc #'id) > (string->identifier "abc" srcloc) #<syntax:eval:12:0 abc>
procedure
(identifier-append ids ... [#:srcloc srcloc]) → identifier?
ids : identifier? srcloc : (or/c #f syntax? srcloc?) = #f
Concat multiple identifier into one.
Examples:
> (identifier-append #'ab #'c) #<syntax abc>
> (identifier-append #'hello #'- #'world) #<syntax hello-world>
When srcloc is provided, the srcloc of the result will follow the given.
Examples:
> (define srcloc #'id)
> (identifier-append #'hello #'-world #:srcloc srcloc) #<syntax:eval:16:0 hello-world>
