Problem Installing 'J' Programmer's Editor (Linux)

DavidMD · 05-25-2003, 05:28 PM

Hello, everyone.

I am trying to install and use 'J', a programmer's editor that is written in Java:

> http://www.armedbear.org/
>
> J - Programmer's Editor Written in Java
>
> J is a multifile, multiwindow programmer's editor
> written entirely in Java. It has syntax highlighting
> for Java, C, C++, XML, HTML, JavaScript, Lisp, and
> Perl, automatic indentation, directory buffers,
> regular expressions, multifile find and replace,
> autosave and crash recovery, undo, and FTP and
> HTTP support. Users can customize all keyboard
> mappings and themes.

I followed the installation instructions exactly and 'J' appeared on my screen.

When I closed 'J', however, I could find no way to relaunch it. Unlike, for example, 'jEdit', there does not appear to be a 'bash' shell script to launch 'J'.

I am running SuSE Linux 8.2 Professional. I know that I must be missing some detail or making a stupid mistake, but I have spent approximately a day trying to resolve this problem, and I cannot.

Any suggestions would be appreciated.

Thank you very much, in advance!

Cordially,

David

P.S. -- I have Java 1.4.1 installed and 'J' can "see" it, just as 'jEdit' can. My problem is in determining how to launch 'J' again after I have closed this programmer's editor. Thanks!

cool software - thanks for the link. =)

what desktop environment are you using? kde - gnome - or just a window manager like blackbox or fluxbox?

not sure if i understand if you have launched it at all yet.

Hi, macewan.

You are welcome for the link.

I think that 'J' will be a very nice programming editor; it looks nice now, and it's not even reached version 1.0.

To answer your question, macewan, I am using KDE 3.1.1 (with SuSE Linux 8.2 Professional).

Thanks!

Cordially,

David

P.S. -- macewan, I am able to see the screen (as you share in your screen capture link), so I assume that I have, indeed, launched 'J'; the problem is with launching it again.

Hello, again, macewan.

Here are the commands I used, minus the extraction of the archive, for installing 'J', which has a buffer open and is running. When I close the terminal window containing the text below, 'J' will "go away" and I have found no way to restart it:

Code:

ddickerson@linux:~> cd /
ddickerson@linux:/> cd /home/ddickerson/Staging/j-0.18.1
ddickerson@linux:~/Staging/j-0.18.1> java -jar j.jar

Incidentally, I am using the compressed binary of 'J' 0.18.1, I could try installing from source, but I do not see how doing so would be of benefit. (Of course, I am a Linux "newbie"!)

I tried following a suggest to type a 'J' in 'xterm' and hit the TAB key twice, but the result was two beeps, one for each time I pressed the TAB key. (I searched the directory and there is no 'bash' script to launch 'J', by the way.)

Thank you, in advance!

Cordially,

David

P.S. -- By the way macewan, usually when I install software I do so from my 'Staging' directory and the software is installed in its default location or in the directory that I specify. In this case, 'J' is installed in the working directory -- which I find to be very odd and confusing. (Plus, I do not want 'J' there.)

Hello, everyone.

I have resolved my problem by creating a shell script to launch 'J' in '/home/ddickerson/bin/':

Code:

#!/bin/sh
# Java heap size, in megabytes
JAVA_HEAP_SIZE=32
exec /usr/lib/SunJava2-1.4.1/jre/bin/java -mx${JAVA_HEAP_SIZE}m ${J} -jar "/home/ddickerson/Executables/j-0.18.1/j.jar" $@

According to the documentation for 'J', there is supposed to be an 'init.bsh' shell script, but I did not have this script after installing 'J'.

I do not know if my solution is a "kludge" or a decent approach, but it does work, at least.

I am a bit concerned, however, about the Java heap size. I do not know if 32k is sufficient for 'J'. If anyone has any suggestions or comments, I would be grateful.

Thank you very much, in advance!

Cordially,

David
