Description: With krep you can view a file. While viewing, you can set and change a filter for the file's content. You can use a regular expression as filter. If no file is given, krep gets its data from standard input.
Example: You want to search in /var/log/message for messages from Aug 30. So, you enter Aug 30 into krep, and it only shows lines containing this string. You see it is still too much, so you enter another key word you are looking for, say, syslog, and click on filter. Then, you will only get lines from /var/log/messages that contain as well "Aug 30" as "syslog".
If you want again more output, you can delete filtering lines and get again more lines displayed.Last changelog:
0.1 - work 0.2 - read stdin in case no argument 0.3 - install in kde-directory, even if it is not /usr/local/kde 0.4 - react on file changes like tail -f 0.5 - "only show lines containing" 0.6 - ignore newline in regex field 0.7 - speed up by factor > 4 0.8 - allow more than 1 filter expression 0.81 - compile with GCC 4.1 0.82 - prompt the user for text input 1.1 - make it compile even if compiler is not permissive
This is a nice start, since its purpose and abilities are clear, so thanks !
Gui applications can never become as crunchy and flexible as their cli counterparts, but they may help less experienced users to dig deeper into things and learn.
What puzzles me is the combination of a simplistic gui (as in "for less experienced") in combination with the use of regexs. So the niche for this application might be a offer good assistance in more complex filter patterns. For this it might make sense to use a more sophisticated regex editor/wizard. Maybe you could re-use something existing or get inspired by looking at some other apps constructing regexes.
Anyway, keep up the good work !
thank you :) You understood what I wanted - bringing regex's to newbies. There are opportunities to improve, but I am taking steps slowly because I do not want to sacrifice simplicity :)

Qt uses value types for many data types, so you always get a copy of those returned from many functions. Because of reference counting, those copies are fast, though.
To change the cursor position, use QTextEdit::setTextCursor(). You can pass your own cursor positions, or the position returned from textCursor().
I fixed this for you. The problem is described at http://doc.qt.nokia.com/4.7/qtextedit.html#textCursor - who in the world wants A COPY of the text cursor to be returned?
Anyway, fixed, please test :)
thanks for the report
Thorsten
thanks for the fix now compile :-)
when i like a software that it's useful i'm became a fan :-P
a suggestion for the program, but a dialog for choose the file to open in the gui it's possibile?
yes that should not be a problem. However at the moment I am discovering myself as a packager (as openSUSE build service suddenly stops saying "set -fpermissive").
Thorsten,
the use of regular expressions in you program beats the plain old crap grep!
Good work!!
ThX
Maybe i'm going to build some rpm packages for openSUSE soon.

I know this error and have a lot to say about it. In a hurry, just delete line 138 and 139 of krep.cpp, thanks for becoming a fan Thorsten

hey Christoph, have you seen my kde-contextmenu that I derived from your favorites menu?

ok I implemented your proposal in version 1.2. It is in svn, not yet packaged. regards Thorsten
