ReplaceSubStringBoundedBy()

ReplaceSubStringBoundedBy(pcWhat, pacBounds, pcNew): replace pcWhat with pcNew only when it sits inside a bounded section. pacBounds may be ["open","close"] OR a single string used both ways. ReplaceSubStringBoundedBy(pcWhat, bounds, :With = new): replace the occurrences of pcWhat that ARE a whole bounded region's content (the same equality contract as FindSubStringBoundedBy; same-string bounds pair with the overlap walk).

Basic examples (2)

Softanza
o1 = new stzString("bla bla --word-- bla bla --nword- bla --word--")
o1.ReplaceSubStringBoundedBy("word", "--", :With = "WORD")
# the method form
? o1.Content()
o2 = new stzString("bla bla --word-- bla bla --nword- bla --word--")
o2.ReplaceXT("word", :BoundedBy = "--", :With = "WORD")
# the XT form
? o2.Content()
Output
bla bla --WORD-- bla bla --nword- bla --WORD--
bla bla --WORD-- bla bla --nword- bla --WORD--

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
yes
does what the method does, then returns the object, so the call can be chained · ReplaceSubStringBoundedByQ
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
yes
takes bounds that are included (IncludingBounds) · ReplaceSubStringBoundedByIB
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
