| Summary | FUNCT option to define a persistent local object, or bind to an existing object |
|---|---|
| Description |
It would be helpful to be able to optionally define persistent local words for a FUNCT function, or to safely bind the function's code block to a provided object. Some use cases: - Handlers with predefined specs and persistent local words. - Handlers bound to the object they are handling for, after the object is defined. - Functions with local functions (like SECURE). - Contexts with local words but one exported function (like PARSE-URL). - Contexts that currently have global functions defined with SET 'name. - Functions with local values preconstructed using COMPOSE of the code block (like many PARSE wrappers I write). This has the additional advantage of being able to define what in other languages are called "friend" functions. This proposal is an alternative to #749. |
| Example code |
ascii?: funct/with [ "Returns TRUE if value or string is in ASCII character range (below 128)." value [any-string! char! integer!] ] [ either any-string? value [parse/all/case value [any ascii]] [value < 128] ] [ ascii: charset [#"^(00)" - #"^(7F)"] ] |
