Where can I find the printable statements in BlackBerry Eclipse IDE. The console which I see does not gives me the string which I print
System.out.println("User1 "+Username);
It just shows:
Packaging project HelloWorld

If you want to execute some print statements like
System.out.println("Test")
to track your application status, you should debug your application to get your print statements. It will not print the statements if you run your application normally.
Do Right Click your application, and click Debug as yourapplication, and then you will be able to get print statements

I just cannot figure out how to show logging messages when running dart files from terminal.
Example example.dart:
import 'dart:developer';
void main() {
print('print');
log('log');
}
Expected output:
print
log
Actual output:
print
I tried calling dart example.dart, dart run --all example.dart, dart run --verbosity=all example.dart, and different values instead of all (info, ...).
But non of these produced any helpful error messages let alone the out print I expect.
APIs from dart:developer (such as log) are intended to interact with debugging tools:
Interact with developer tools such as the debugger and inspector.
It's not explicit from the documentation for log, but I'd expect it to send a log message only to an attached debugger, not to the console.
If you want logging output that is independent of a debugger, use package:logging and add a listener that calls print, as shown by the example.
I am writing a small program in Progress that needs to write an error message to the system's standard error. What ways, simple if at all possible, can I use to print to standard error?
I am using OpenEdge 11.3.
When on Windows (10.2B+) you can use .NET:
System.Console:Error:WriteLine ("This is an error message") .
together with
prowin32 2> stderr.out
Progress doesn't provide a way to write to stderr - the easiest way I can think of is to output-through an external program that takes stdin and echoes it to stderr.
You could look into LOG-MANAGER:WRITE-MESSAGE. It won't log to standard output or standard error, but to a client-specific log. This log should be monitored in any case (specifically if the client is an application server).
From the documentation:
For an interactive or batch client, the WRITE-MESSAGE( ) method writes the log entries to the log file specified by the LOGFILE-NAME attribute or the Client Logging (-clientlog) startup parameter. For WebSpeed agents and AppServer servers, the WRITE-MESSAGE() method writes the log entries to the server log file. For DataServers, the WRITE-MESSAGE() method writes the log entries to the log file specified by the DataServer Logging (-dslog) startup parameter.
LOG-MANAGER:WRITE-MESSAGE("Got here, x=" + STRING(x), "DEBUG1").
Will write this in the log:
[04/12/05#13:19:19.742-0500] P-003616 T-001984 1 4GL DEBUG1 Got here, x=5
There are quite a lot of options regarding the LOG-MANAGER system, what messages to display, where the file is placed, etc.
There is no easy way, but in Unixen you can always do something like this using OUTPUT THROUGH (untested):
output through "cat >&2" no-echo unbuffered.
Alternatively -- and this is tested -- if you just want error messages from a batch-mode program to go to standard out then
output through "tee" ...
...definitely works.
When running QTest in Qt Creator with terminal setting disabled, the output pane display links to the test line failing, ie:
FAIL! : MidiTest::testMTCWriter() Compared values are not the same
Actual (tcCount): 1
Expected (2) : 2
Loc: [../../Joker/tests/AutoTest/MidiTest.cpp(271)]
Is it possible to make such link? For example I configured doxygen as an external tool and I'd like to produce the same output for documentation errors.
I'm trying to execute a simple erlang program of adding two numbers.
I'm trying to do this in Eclipse on Ubuntu 10.04 LTS.
When i execute this program, I'm getting the error as shown below:
** exception error: undefined function add:addfunc/0
How do i go about solving this error? Thanks in advance.
This program when executed in the erlang shell is working fine. But when it comes to eclipse it's giving me this error. Not this, any program for that matter is giving me the similar error. Guess I would be missing something about the eclipse configuration.
EDIT:
Anyways, This is the sample add program,
-module(add).
-export([addfunc/0]).
addfunc() ->
5 + 6.
This message tells you that module add doesn't have an exported function addfunc/0.
Ensure the function you want to be called has exactly that name, doesn't expect any
parameters, is
exported, the module is
compiled, the search path includes the compiled beam file and that there is no module clashes using code:clash()
Update
It's not clear how erlide (eclipse erlang plug-in you seem to use) compiles and runs a program. Try to compile source using erlc or inside erl shell. That way you'll have much easier controllable environment and you'll better understand what's going on.
I got exactly the same problem -for a tail recursive fibonacci function- below:
-module(math2).
-export([fibonacci/1]).
fibonacci(0) -> 0;
fibonacci(1) -> 1;
fibonacci(M) -> fibonacci(M-1) + fibonacci(M-2).
In the end, had realized that this is a compile-time exception. Then, have opened a new tab on my shell and tried with erlc, instead of erl.
$ erlc math2.erl
Now I am also able to see math2.beam file created.
Called fibonacci with 10:
4> math2:fibonacci(10).
55
and it worked!
I think you have not compiled the code and you are trying to run the program.
In eclipse, using the "Run" icon, trigger the run; which will get you to the erl shell in the console window.
There you do -
cd("C:\Learning_ERL\src").
And you should see output like-
(Learning-ERL#DALAKSHM-MNFSM)7> cd("C:\Learning_ERL\src").
c:/Learning_ERL/src
ok
Then compile the code -
c(add)
you should see something like this on the erl shell-
(Learning-ERL#DALAKSHM-MNFSM)10> c(add).
{ok,add}
Now you should be seeing a new file called - add.beam in the same directory as that of your erl source file - add.erl
add.beam is a bytecode file
Now you should be able to run the program without any error
How do you try to execute your code?
In your editor, right-click and choose "Run as"->"Erlang application". The VM that is launched will have your project loaded automatically and when editing/saving a file it will get reloaded. When launching, a console appears and you can call your code from there.
If it still doesn't work, what message do you get for m(add).?
I am using System.out.println() to print Output to the eclipse console.
System.out.println("test");
System.out.println("test1");
System.out.println("test2");
System.out.println("test3");
I am getting the following:
[2785.375] test
[2785.382] test1
[2785.382] test2
[2785.382] test3
How to remove the line numbers before the time stamp values? It is getting annoying sometimes.
Thanks,
