Code: Select all

;IDEA 1: xxxC/xxxP operators

if (var contains StrSplit("abc,def,ghi", ",")) ;we need *SOMETHING* better than this
if (var contains "item1,item1ctd,item1ctd") ;1 item
if (var containsC "item1,item2,item3") ;3 items (no special ',,' handling)
if (var containsP "item1|item2|item3") ;3 items (no special '||' handling)

;contains, containsC, containsP
;in, inC, inP
;starts, startsC, startsP ;potentially
;ends, endsC, endsP ;potentially

;note: the xxxP operators are useful for needles that contain commas and for conversion to/from ~= (RegExMatch)

;==================================================

;IDEA 2: StrSplit comma/pipe unary operators

if (var contains StrSplit("abc,def,ghi", ",")) ;we need *SOMETHING* better than this
if (var contains "item1,item1ctd,item1ctd") ;1 item
if (var contains splitc "item1,item2,item3") ;3 items (no special ',,' handling)
if (var contains splitp "item1|item2|item3") ;3 items (no special '||' handling)

;note: perhaps a 'split' or 'splitx' operator would split every character (n-length string to n-length array)

;note: alternatively/additionally, a binary operator: "a,b,c" split "," [although this puts the operator after the string, where it's less visible, and easy to miss]
;[EDIT:] if (var contains "abc,def,ghi" split ",") [not great, less clear than StrSplit()]

;Objects
;https://hotkeyit.github.io/v2/docs/Objects.htm
;When a non-object value is used with object syntax, the default base object is invoked. This can be used for debugging or to globally define object-like behaviour for strings, numbers and/or variables. The default base may be accessed by using .base with any non-object value; for instance, "".base. Although the default base cannot be set as in "".base := Object(), the default base may itself have a base as in "".base.base := Object().

      if (state ~= word)       ; ~= is short hand for RegExMatch().
