This is a little set of words to create an array with all of the
|
|
currently defined namespaces in a RETRO image.
|
|
|
|
Three words will be exposed.
|
|
|
|
Namespace Array, holds the namespace strings
|
|
namespaces:identify Rebuild the array
|
|
namespaces:put Display the namespaces
|

'Namespaces d:create #513 allot
|
|
|
|
{{
|
|
:has-namespace? dup $: s:contains-char? ;
|
|
:get-namespace $: s:split nip ;
|
|
:known? dup &Namespaces a:contains-string? ;
|

:add s:keep buffer:add &Namespaces v:inc ;

:namespaces:put &Namespaces [ s:put sp ] a:for-each ;

A quick test:
|

|
|
```
|
|
namespaces:identify
|
|
namespaces:put nl

```
