Hi,
I've been thinking of adding the following metadata 'feature' to Liitin, but
I wonder if this could be of more generic use. What do you think about the
idea?
(meta ((tooltip "This is a tooltip"); plain text
(manual (fetch-manual-chapter 'object-x)); Rich-text format
(self-test 'object-x); associated test cases to assure
... ; bugfree and compatible updates
))
e.g.
(define (function-x args)
(define ...)
(meta ( ()()() ) )
(begin ...))
Helpers:
(meta-exist? object-source meta-type) >> true/false
(get-meta object-source meta-type) >> meta-content
(put-meta! object-source meta-type meta-content) >> modified object source
- Object-source can be either provided as source code or as a reference
where to fetch it (incl. comments, formatting etc.)
Features/ reasoning:
- Object internal metadata information.
- Self-contained, not requiring a special infrastructure.
- Return actual metadata content rather than human navigated link.
- Can refer to external objects to keep the main object compact,
and allow separate development for each metadata.
- Could return localized versions (up to metadata provider).
- Applications can utilize the metadata on-the-spot, without opening
external viewers or requiring human interaction (e.g. displaying tooltip
when hovering on top of a function, or offering extra functionality on
context menu).
- 'define' level declaration.
- Different object versions/variants are free to use common metadata.
