Bug ID: 365124
Summary: Regex capture groups for text fails beyond \9
Product: kate
Version: 3.14.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: nealky...@gmail.com
Regex capture groups for text fails beyond \9, but works for numbers. In other
words, \10 is interpreted as capture group \1 with 0 appended. But for numbers
it is correctly interpreted as capture group \10
To demonstrate, here are some examples.
(with numbers, works correctly)
text:
1 2 3 4 5 6 7 8 9 10 11 12 13
regex:
^([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*)
([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*) ([0-9]*)$
replace with:
\1::\2::\3::\4::\5::\6::\7::\8::\9::\10::\11::\12::\13
result:
1::2::3::4::5::6::7::8::9::10::11::12::13
(with text, does not work)
text:
one two three four five six seven eight nine ten eleven twelve thirteen
regex:
^(.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*)$
replace with:
\1::\2::\3::\4::\5::\6::\7::\8::\9::\10::\11::\12::\13
result:
one::two::three::four::five::six::seven::eight::nine::one0::one1::one2::one3
For the text example, you get the same result even when the regex is:
^([^:]+) ([^:]+) ([^:]+) ([^:]+) ([^:]+) ([^:]+) ([^:]+) ([^:]+) ([^:]+)
([^:]+) ([^:]+) ([^:]+) ([^:]+)$
Reproducible: Always
Steps to Reproduce:
1. Enter text
2. Enter regex
3. Enter replacement
4. Click 'Replace All'
Actual Results:
one::two::three::four::five::six::seven::eight::nine::one0::one1::one2::one3
Expected Results:
one::two::three::four::five::six::seven::eight::nine::ten::eleven::twelve::thirteen
