[Truth test fails]

 [1/7] from: tim::johnsons-web::com at: 18-May-2004 13:53


I'm seeing unexpected behavior from a truth test in a context. Here is the code for the context: writer: make object![ keys: [bold size color family] bold: true bold-tag: "" bold-end-tag: "" fix: func[args[block!]][ foreach [key val] args[ ?? key if not find keys key [ make error! reform[key "is not an acceptable key for htm-writer. Use:" keys]] set in self key val ] ?? bold either bold [ print "creating tag" bold-tag: "<b>" bold-end-tag: "</b>" ][ print "no tag" bold-tag: "" bold-end-tag: "" ] ] ] Now here is sample code execution:
>> writer/fix [bold false]
key: bold bold: false creating tag == "</b>" I would expect that the false-block for 'either would be executed. What am I doing wrong? thanks tim -- Tim Johnson <[tim--johnsons-web--com]> http://www.alaska-internet-solutions.com

Hi Tim, just little notice...sometimes it is useful to know also this this kind of syntax(although in your case it is better to use get IMO)
>> a: [false #[false]]
== [false false]
>> type? a/1
== word!
>> type? a/2
== logic!
>>
regards, Cyphre

I'll be darned. I didn't realize that one could do that. What would be the use for that feature? Thanks tim

It's only in the beta versions, not in 1.2.1.

Saves the need for a compose, I guess... a: compose [false (false)] -- Carl

Hi Tim, | What would be the use for that feature? | It's usefull e.g. when you MOLD or SAVE what you want to LOAD easily:
>> mold none
== "none"
>> mold/all none
== "#[none]"
>> type? load mold none
== word!
>> type? load mold/all none
== none!
>> save/all %/c/test.r none >> load %/c/test.r
== none
>> type? load %/c/test.r
== none! The same feature applies for objects, too:
>> mold/all context [a: 5]
== { #[object! [ a: 5 ]]}
>> type? load mold context [a: 5]
== block!
>> type? load mold/all context [a: 5]
== object! HTH, Christian
