Comment:
ok, i've test rebuild from source rpm from:
- mc-4.7.0-0.7.pre4.fc13.src.rpm
- mc-4.7.0.pre4.148.g1f900af-1.fc12.src.rpm
the problem still exists with both version above.
fyi, expected result should be the same as doing this command on Vi or Vim
{{{
%s/^/TEST/g
}}}

Comment(by andrew_b):
Another test case:
1. Open emtpy file (Shift-F4).
2. Type "123456"
3. Place cursor to '4' symbol.
4. Call replace dialog. Set search string to '^', set replace string to
"aaa". Select "Regular expression". Press Enter.
5. Press "Replace" in "Confirm replace" dialog.
6. Replacement result is "123aaa456". Expected result is "aaa123456" (as
in ViM).
In any case the replacement starts from current cursor position, but
sometimes such behaviour produces incorrect results.

Replying to [comment:3 andrew_b]:
> Set search string to '^',
Set search to '!^' ("line start" regexp).

Comment(by fp):
hello,
sorry for late respons, here some updates for this bug:
== replace with REPLACE button, now works well (line by line), with single
{{{'^'}}} mark on search string.
as in Vim:
(REPLACE) : {{{s/^/123/g}}}
== replace with REPLACE and ALL button, now works well, while char(s)
follow the {{{'^'}}} mark.
as in Vim:
(REPLACE) : {{{s/^a/123/g}}}
(ALL) : {{{%s/^a/123/g}}}
example:
file content:
abc
abc
abc
search string:
{{{^a}}}
replacement string:
123
result:
123bc
123bc
123bc
== replace with ALL button, __still buggy__, with single {{{'^'}}} mark on
search string.
as in Vim:
(ALL) : {{{%s/^/123/g}}}
tested on:
* 4.7.0.9 (source build)
* mc-4.7.4-1.fc12.x86_64
tq,
