Make Lanterna work with Java 1.4.2 #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

I can only use java 142. Can you please, post the jar file that has class files 
compiled with java142. I am restricted to use Java142 and I am trying out a 
different Operating system. I am trying to use this on IBM 4690. I found this 
useful, because it doesnt use any native DLLs. Please feel free advice. Also, I 
would be grateful if you can compile the source against 142.

Thanks,
Sunil.

Hi, sorry, I though Google Code would email me when someone created an issue 
but it apparently doesn't because I didn't see this until now.

About Java 1.4.2, Lanterna is using a fair amount of Java 5.0 functionality, 
but I do see a use for it in older system. I'll try to see if I can make 1.4.2 
branch.

Which functions do you need? Only the terminal/screen? The whole GUI?

Hello,

Thanks for replying. Apparently, I thought the same. May be google code
doesnt inform you when a issue is created. So, I tried all fascinating
things like, starring it and stuff.
First of all, I need the whole GUI. Then, let me explain my problem
statement. I had to develop a project, that uses text user interface much
like Java graphics, where you have multiple text boxes (where you can tab
through) and then some buttons. Clicking on that button, would make the
data persistent (save to a file).

My basic problems here are, I use a different operating system (IBM 4690
OS). All the libraries that I found, used native calls and those DLLs would
not work on my OS. So, I was looking for a pure java thing, that could
resolve my problem. According to the documentation you had on google, I
found that your project accomplishes my objective. Do you think so ? Any
other insights are welcome.

Another limitation is, I can only work with java 1.4.2 .If you can make a
branch, that will be really helpful.

Please let me know your insights on this.

Thanks a bunch,
Sunil.

One quick question, does your Java implementation support sun.misc.Signal 
and/or sun.misc.SignalHandler? I guess the chances are pretty slim, ne?

Lanterna is currently using it to catch the WINCH Unix signal, telling the 
program the terminal size has changed.

What jar file is it present in ? Does it come with JDK ? Dont you think it
will work if it comes with JDK ?

Original comment by sunildas...@gmail.com on 1 Nov 2011 at 6:07

GoogleCodeExporter commented 9 years ago 
Yeah, it comes with the Sun JRE and it isn't a part of the Java standard but 
several JREs implements them anyway.

GoogleCodeExporter commented 9 years ago 
I use IBM's version of JRE. So, I am not sure, it would be present and the
OS would support that. Anyways, I would like to give it a try, if you can
give a branch of Java 142. Thanks for all the help.

I've attached a Java 1.4.2 compiled version of the library. Please give it a 
try and let's try to fix any issues as they come up.

Thanks for making a branch. I would not get much time to work with that
this weekend. I would probably get back to you by early next week.

I guess you are using java.util.Queue which is a java 1.5 feature. So, I am
unable to resolve this.

Original comment by sunildas...@gmail.com on 10 Nov 2011 at 6:07

GoogleCodeExporter commented 9 years ago 
Ok, I'll try to see if I can eliminate all queues.

Original comment by mab...@gmail.com on 10 Nov 2011 at 11:58

GoogleCodeExporter commented 9 years ago 
Ok, here's a new version with no java.util.Queue:s, let me know how it works...

Try creating your LanternTerminal like this:

I am sorry, if I forgot telling this. I am working remotely without a
display attached to the machine via SSH. That was my whole problem in going
for something like this. I would have to access remotely. I would not have
a console attached to the machine, instead, I use a terminal emulator.

Original comment by sunildas...@gmail.com on 6 Dec 2011 at 1:56

GoogleCodeExporter commented 9 years ago 
Terminal emulator is fine, that's how I use it as well. The stacktrace above is 
for another method that wasn't introduced until Java 5. I'll make a new jar 
tonight.

Hmm, this seems to be an exception in JVM, but it probably has something to do 
with the exec:s. First, let me try something I should have tried from the 
beginning; I'll download a 1.4.2 JVM myself and just verify everything's 
working. Then, probably we'll need to guard against these external programs not 
existing.

Original comment by mab...@gmail.com on 20 Dec 2011 at 12:52

GoogleCodeExporter commented 9 years ago 
Alright, new year, new attempts!
I've actually downloaded the Sun 1.4.2 JRE and tried it myself, which resulted 
in a number of new API incompatibilities found. Now, even with those fixed, I'm 
not expecting the issue you had above to go away. But anyway, could you please 
try running the org.lantern.test.TerminalTest class in this JAR on your IBM 
JVM, just to be sure?

I returned to this last night and I realized one potential problem. 
At first, I thought it was possible to remove all calls to external programs, 
but I now saw there are three calls I'm not sure we can do without...

These are:
=/bin/stty echo= or =/bin/stty -echo= for enabling/disabling key echoing
=/bin/stty min ##= for setting the minimum characters for a complete read
=/bin/stty -icanon= or =/bin/stty icanon= for enabling special key commands

Can you check if there is a stty program in your IBM environment? It might not 
be in  /bin directory, this is probably causing the error above. Also, see if 
it takes the same parameters as Solaris/Linux does.

Very interested in making this work in a Java 1.4.2 environment as well.  I 
have the same issues as what is described in this thread.  Just wondering where 
this was left and if it is possible to have this project work in the 1.4.2 
environment as described here.  thank you!!!

Original comment by radius...@gmail.com on 1 Jul 2014 at 8:50

GoogleCodeExporter commented 9 years ago 
I kind of gave up on this, since I didn't the hardware to test it on. Making it 
language compatible with 1.4.2 is one thing, but since we rely on stty in unix 
environment to turn off key echo, line buffering and such, I have no way of 
testing it. Without setting these properties, the library is pretty much 
useless as we can't reliably read input.
