[REBOL] problems creating a path

From: antonr:iinet:au at: 2-Jun-2003 0:20

I am trying to call a function with certain refinements present or not present, depending on user switches. This is one example that gives me what I want: files?: true join 'my-func/test either files? ['files][[]] ;== my-func/test/files files?: false join 'my-func/test either files? ['files][[]] ;== my-func/test That joins onto the lit-path! 'my-func/test successfully or leaves it alone. But this example is difficult to make work, because all the refinements of the path are optional, so the path starts as only a single word!: files?: true folders?: false to-path reduce ['my-func either files? ['files][[]] either folders? ['folders][[]]] ;== my-func/files/[] How to get rid of the brackets? I tried also: to-path reduce [to-lit-path 'my-func either files? ['files][[]] either folders? ['folders][[]]] ;** Script Error: Invalid argument: 'my-func ;** Where: to-path ;** Near: to path! :value join to-lit-path 'my-func [either files? ['files][[]] either folders? ['folders][[]]] ;== my-func/files/[] So using a block for the second argument is not going to work. (Anybody know a way?) Finally I went back to how it was working to start with: join join to-path 'my-func either files? ['files][[]] either folders? ['folders][[]] ;== my-func/files It seems less nice, but it works.
