Nedit copy/paste failure

Posted 12-09-2012 at 05:55 PM by flshope

At the risk of revealing myself to be a computer muggle, I will start by saying that I do most of my code writing/editing using NEdit. I have been using NEdit for most of a decade. I know I should learn Emacs, but I just haven't gotten around to that. I like NEdit a lot, except for one fairly serious problem ...

Seemingly at random, when I have multiple instances of NEdit running simultaneously, the copy/paste function suddenly stops working on all instances. Closing all NEdit sessions and restarting them seems to clear the problem, but that's too traumatic.

If NEdit was started from a terminal window, it will generate error messages saying something about clipboard lock after the copy/paste failure occurs. When NEdit's copy/paste fails, other applications seem to continue working normally in terms of copy/paste.

I have searched on-line for others' experience with this problem, and I found many mentions of this going back many years. I have not found any suggested solutions.

I have observed the problem under Red Hat Enterprise and Ubuntu (currently 12.04 LTS). Some posts suggest it may be OS-dependent.

In the last few weeks or so, I have noticed a suspected but unconfirmed connection with another NEdit event: the copy/paste failure seems to occur when one or more of the NEdit instances have open a modified file, i.e., changes that have not been saved. It seems that when the save is accomplished, the clipboard lock goes away and copy/paste begins working again.

This is a tentative conclusion and may not be correct. I will report any further developments on this problem.

    Reporting back on some subsequent observations ...

    From my previous post:

    I now have specifically observed that, when the copy/paste failure has occurred while one instance of NEdit has unsaved changes, saving those changes sometimes clears the copy/paste failure in other NEdit instances. I have observed this result several times.

    However, I also have observed instances where the save did not clear the copy/paste failure. Sometimes it works and sometimes it doesn't.

    geesh sounds like its time to invest the time in emacs maybe... I actually learned emacs before vi believe it or not. Being a .ılılı..ılılı. guy learning emacs was great because the Cisco IOS uses the same keys for editing command line ;^}

    For the longest time I avoided vi like the plague... but trust me... taking the time to learn it really doesn't take that long and it the long run is a HUGE benefit.

    So if your going to be (x)nix guy... learn vi... and if you're a programmer learn emacs.

    Thank you for your thoughts and recommendation.

    You're right, no doubt about it. Before I start another programming project, I need to have emacs under my belt. When I have 10 or so text file windows open, closing and restarting them all to fix copy/paste is a real enthusiasm killer.
