Bug ID: 98566
Summary: calc online and offline help: add escaping for
searching parentheses in regular expression
Product: LibreOffice
Version: 5.0.4.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
related to offline and online help (german, but also english)
to find here: help.libreoffice.org/Common/List_of_Regular_Expressions/
i'm missing the hint that one also needs to escape a parenthesis for finding it
in regex search; so there should be a hint in this paragraph:
( ) In the Search for box:
Defines the characters inside the parentheses as a reference. You can then
refer to the first reference in the current expression with "\1", to the second
reference with "\2", and so on.
For example, if your text contains the number 13487889 and you search using the
regular expression (8)7\1\1, "8788" is found.
You can also use () to group terms, for example, "a(bc)?d" finds "ad" or
"abcd".
--- hint start ---
For searching a parenthesis you should escape it: "\(" finds a "("
--- hint end ---
I know it's slightly redundant, but just to clarify it for the nonprofessionals
in regular expressions ...
Or perhaps there should be a row on the top below "Any character":
"Special characters": All characters used here for building regular expressions
have to be escaped to find the literal characters: <list of this special
characters>
thanks for the good work!
