How do i read from a console???
Let me describe you the sitiuation.....
I have a plugin, which has to read the console messages.
(Its not something like using System.in to read console inputs).
ie.,
During the compilation of the C file,
the compiler used to generate compilation messages and these messages got
printed in the console.
Is there any way to read that console messages...???
Any suggestions please....!!!
Thanks for your time....
Regards,
Ravi.

Thanks Christian for the comments......
i have Plugin X which has a c/c++ compiler in it, which gives the
compilation messages on Build.
I dont have any control on it.(so i cannt redirect it to my application)
Also, i dont have any knowledge on how those messages are streamed to the
console.
Now i want to create a plugin Y which should listen for the console
messages given by the other plugin(Say Plugin X) and capture it.
Is there an option to add a listener to the console, so that when ever the
console gets the data, can we read it from there....
or is there any other option to do it....???
Any ideas ...???
Thanks and Regards,
Ravi.

Are you using the CDT or aren't you? If you are - there is an extension
point that allows you to hook error parsers up to the console output
(which is exactly what Derek said).
If you are not using the CDT, and you currently have the build output
going to an Eclipse process console, have a look at the following
extension points in the online help:
org.eclipse.debug.ui.consoleLineTrackers
org.eclipse.ui.console.consolePatternMatchListeners
I guess to help any further, if you are still confused, we need to know
more about how your compiler is launched. Is it launched from the CDT
automatically, or are you running an external tool, or have you done
something entirely custom in your own plugin?

Hi Mark....
Thanks for the helpful...
It was really useful....
I created a parser using cdt Errorparser extension point.
Through that parser am pipeing my console output to a file.
Is there a way to enable my error parser by default???
Because at first this error parser should be enabled in preference
settings,
otherwise, the parser wont be active.
Is there a way to do it???
Thanks in advance,
Regards,
Ravi.

See the Managed Build System Extensibility Document, which is in the help
supplied with the CDT SDK.
The explains how to add a complete toolchain to CDT (including doing what you
require).

Hi,
Thanks for the help,
I created a parser using cdt Errorparser extension point.
i am getting the build messages with the help of it.
public boolean processLine(String LINE, ErrorParserManager arg1)
{
==> LINE gives the Build messages line by line.
}
But, i want to know the end of the build message.
ie.,
when we give "Build project" the build process takes place and we are
getting build messages for that project. Is there any function which will
indicate that this is the end of the build message???
Because, at the end of the build message i want to parse the Build
messages,
Since i dont know when i will get the last line of Build message, i dont
know when i should start other activity(Parsing the final output).
Is there a function, which will indicate the END of the Build messages???
Thanks in advance...
Regards,
Ravi.

Why wait until the end? Just process the data as it arrives. You' get EOF when
it finishes.

Hi,
This is my code for getting console messages...
public class myParser implements IErrorParser {
ArrayList<String> consoleDatas = new ArrayList<String>();
public boolean processLine(String line, ErrorParserManager arg1)
{
consoleDatas.add(line);
return false;
}
}
In the array list am storing the datas,
The processLine(String line, ErrorParserManager arg1) function gives the
console messages line by line.
SO, i can start processing the data once i get form the function. That i
agree.
But, is there a way to check the End of build messages.
Because,
"String line" doesn't carry EOF or null to indicate the End of the
Build messages.
"ErrorParserManager arg1" does this arg1 helpful in this case???
The problem would be, when am selecting more then one project and giving
build command, at that time i will get build meaasges for the project one
after the other. I will get every thing in one string, i just thought of
seperating it per project if there is any way to do it over here.
Thanks and Regards,
Ravi.
