Lister for Krusader

ckarai · Developer Joined: 17 Sep 2003 Posts: 512

Now Krusader in KDE SVN contains a lister module for viewing the huge files.

Please reinstall Krusader to be able to use Lister's most functionality.

How it works:
- checks whether a text file is bigger than 10 MB (configurable), and if
yes, then Lister is used instead of KDE's default viewer
- the old hex viewer was decomissioned, Krusader calls Lister to view
hex files as well
- lister never loads the whole file into memory, just a little part of
it, and uses caching for faster scrolling
- remote files are downloaded, but during the download, viewing the
downloaded part is possible
- if a file constantly changes, then it can also be viewed, lister will
always see its current state

Please test is, as Lister is huge (>= 2400 lines), so there can be many
bugs in it.

Lister also provides searching (hex, regexp, as well), printing,
changing the encoding,...

Thanks,

Csaba

Hi,

the KDE SVN does mean, that the old command:
svn co http://krusader.svn.sourceforge.net/svnroot/krusader/trunk/krusader_kde4 doesn't work anymore to get the actual SVN version?

So please can somebody help me, what must I do to get only the new SVN of krusader without the other KDE extragear stuff

Thanks. Sysitos

And I do it again, answer my question

Krusader is now in KDE4 extragears repo and the new command to get the SVN is:

svn co svn://anonsvn.kde.org/home/kde/trunk/extragear/utils/krusader

The new svn builds with some warning messages.

It seems, that the svn is now complete in english, no more german translations anymore (yet?).

Found a bug in the listener. Trying to search the new line with regexp (\n, but same problem for other regexps like ^) in a file, but Krusader crashes instantly:(

Btw, thanks for the new quick listener.

Hi,

the translations are separated in the KDE repository. I don't know how to get them.

I can't reproduce the crash in Lister. Can you please send the trace?
Or please try building Krusader from scratch.

BTW you'll never be able to search '\n'. Krusader splits the file by new lines, and searches in the lines (which no longer contain \n).

Use abc$ instead.

Hi Csaba,

it was my hope to search for new lines with \n (but that's another story

)
Rebootet the system (there were some kde updates) to ensure no other problems. Krusader was built from scratch. (Removed the old svn from krusader page before do a new svn from kde page).

Reproduced the bug while searching for \n in listener module. No such problem with the other modules.

To reproduce this, try to search for \n (I known now, doesn't make sense for regexp, but shouldn't crash Krusader, even If I search without regexp) and hit the next button. Ok, I've tested some different text files and Krusader does only crash, if the background of the search field (with "\n" typed in) is still white and than crashs with hitting the next button (or I press Enter). For smaller files, I see some kind of progression bar for searching the file, for bigger files Krusader does crash. Have here a 700kB and a 10 MB file, both do crash, but smaller files (680 KB and smaller tested) don't crash at all.

Here is some output from the KDE Crashmanager. I don't have all the debug packages installed at the moment, so it wouldn't be much helpfull ;-( (Will do this, if that does help, but the laptop isn't the fastest one.)

Fixed the crash in Lister.

Sometimes the cache reported wrong number of the available bytes.
This crash had nothing to do with '\n'.

@ Csaba, lister doesn't crash here anymore. Thanks for the quick bug hunting.

@Dirk, if you will get informations for the translated versions of krusader, don't wait to inform us

This is maybe a naive question, but how much work would be required to make a KPart out of the Lister so other KDE programs (like Dolphin) could use it? The added value for Krusader would be that other KDE developers might add something to it as well

ckarai · Developer Joined: 17 Sep 2003 Posts: 512

Lister is a KPart.

But it's outside of KDE (not registered into the mime handlers).

Are there any news regarding compiling the SVN with german translation? Besides the quick hack from dirk?

Thanks sysitos
