@ -12,7 +12,19 @@ Changes in Guile 1.2:
|
|||
|
||||
* Changes to the procedure for linking libguile with your programs
|
||||
|
||||
* Changes to Scheme functions
|
||||
* Changes to Scheme functions and syntax
|
||||
|
||||
** Guile now supports a new R4RS-compliant syntax for keywords. A
|
||||
token of the form #:NAME, where NAME has the same syntax as a Scheme
|
||||
symbol, is the external representation of the keyword named NAME.
|
||||
Keyword objects print using this syntax as well, so values containing
|
||||
keyword objects can be read back into Guile.
|
||||
|
||||
Guile suports this read syntax, and uses this print syntax, regardless
|
||||
of the current setting of the `keyword' read option. The `keyword'
|
||||
read option only controls whether Guile recognizes the `:NAME' syntax,
|
||||
which is incompatible with R4RS. (R4RS says such token represent
|
||||
symbols.)
|
||||
|
||||
** Guile has regular expression support again. Guile 1.0 included
|
||||
functions for matching regular expressions, based on the Rx library.
