Description ppww 2010-04-09 23:50:38 UTC
I'd like to append a tab, followed by additional text (the digit 1), to the end
of each line of a selection.  In the Find & Replace dialog, I enter

Search for: $
Replace with: \t1\n
(Regular expressions checkbox selected)

But this appends a literal "\t1" to the end of each line, instead of the tab
character.  Same with \x0009, which inserts those literal characters instead of
the tab control character.

Search for: (.*)$
Replace with: $1\t1

A few more possible bugs are evident when using the workaround:

The back-reference \1 does not work, it must be $1.

The expression does not find blank lines, even though the any-character (.) is
optional (*).

And in the workaround case, it is not necessary to include \n in the
replacement, as the newline is not removed by the search expression.  (The
newline is removed if only $ is specified as the search.  Inconsistent behavior.)

My reference is
which indicates that \t, \x0009 and \1 etc. are supposed to work in replacement
expressions.  \t does work as a replacement in cases other than a single $
search, but \x and \1 seem never to work as described.  \n in the replacement
works as expected in all cases that I've tried.

Addendum: Sorry, ignore the comments about \1 and \x failing in replacement.
I understand now that those match in the search expression only.
The main point, that \t fails, is still valid.

I can confirm this on both, 3.2.1 and DEV330m8: \t introduce a tab for any
replaced text EXCEPT when it replace an end of paragraph, in which case it
introduce "\t" as text

Really a crazy thing, works anywhere fine, only if the \t is the first in the replace pane and $ the last in the find pane the problem appears
