During tree construction, internal lookup tables control the rendering
transformations. You can add to them using procedure qcons-declare!.
[NOTE: docs missing for qcons-declare!]
The rest of this section presents various lists of built-in declarations.
Using qcons-declare! on a built-in symbol overwrites the associated
value (if any). There is no undeclare support.
These are the infix operators.
|| ||/ |/ / !! % ^
* - + @ & | # <<
>> ## && &< &> <-> <^
>^ ?# ?- ?-| @-@ ?|
?|| @@ ~= <<= >>= =
< <= > >= <> != all
any in like not-like ilike
not-ilike ~~ !~~ ~~* !~~*
similar not-similar ~ ~* !~
!~*
These are the postfix operators.
! null? not-null? true?
not-true? false? not-false?
unknown? not-unknown?
Display aliases exist for these symbols.
null? not-null? true?
not-true? false? not-false?
unknown? not-unknown? not-like
not-ilike similar not-similar
These functions render differently depending on the presence of keyword args.
