MatchingSubStringsAndTheirPositions()

Same as MatchesZ: This used to print @@(FindMatches()) and return nothing, which made the four aliases below -- every one of them named ...AndTheirPositions -- answer NULL while dumping to the console. Nothing carried a position at all.

Basic examples (1)

Softanza
oRx = new stzRegex("[0-9]+")
oRx.MatchXT("a12b345c6", 1, :MatchFirstOccurrenceIfNotGoPartial, [])
# Matches gives the values
? @@(oRx.Matches())
# MatchesZ gives value and position
? @@(oRx.MatchesZ())
# ...as DATA, not as console output
? isList(oRx.MatchesZ())
# ...one entry per match
? len(oRx.MatchesZ())
# ZZ gives the position as a SECTION instead
? @@(oRx.MatchesZZ())
# ValuesAndTheirPositions agrees
? @@(oRx.ValuesAndTheirPositions())
# ...and so does MatchesAndTheirPositions
? @@(oRx.MatchesAndTheirPositions())
# ...and it is not empty
? len(oRx.MatchingSubStringsAndTheirPositions())
Output
[ "12", "345", "6" ]

The extensions of this method

Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).

Extension
Exists
What it adds · The names
Q
no
does what the method does, then returns the object, so the call can be chained
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
no
takes a case-sensitivity flag
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
no
the extended form: more parameters than the base method
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action
Many
no
works on a collection of items instead of one (the plural form)
Except
no
takes exceptions, what to leave out (the exceptional form)
U
no
returns the result without duplication

Every example is a test file of the library, run inside the library for this page; only those whose output kept every promise their file wrote are shown.
