I'm making an eclipse plugin where I want to run a system command, and have the output of the command go to the eclipse console. I know how to do this via http://wiki.eclipse.org/FAQ_How_do_I_write_to_the_console_from_a_plug-in%3F
The problem I don't know how to solve, is to allow interactive input from the console for this command.
In essence, I want to kick off a command which runs in the console. The user can interact with this command (via stdin). I then want my plugin code to get a callback when the command has finished (or user has manually stopped/terminated the command in the console). Getting the return code of the completed program would be nice as well.
For simplicity sake, lets use the unix 'passwd' command as the example (this is the first common cmd I could think of that both has output and prompts for input). I don't need to hide the stdin however.
For reference, the command I'm trying to call is the CakePHP bake shell.
I assume that you got yourself a MessageConsole, like in the FAQ. Then it should be possible to use messageConsole.getInputStream().read() in a loop to get your input (but I have not tested this). See also the documentation of the IOConsoleInputStream for more options.
On the other hand I'm not sure why you are creating your own plugin to do that. The standard console implementation in Eclipse does exactly what you want. You can see that by running a small Java application, where you can use that console for input and output as well.

I have a Scala program that is triggered from a shell script. I'd like to be able to run the program in eclipse in debug mode. Anybody knows how that can be done?
Thanks.
I'm not sure if there is a way to debug both together, but what you can do is run your script with the option -xv. So...
user#mypc$: bash -xv myscript other_args
That will show you the commands that are executed along with their parameters.
Then in Eclipse you can debug your Scala program normally and pass those parameters to it through the main method or run configuration.
Typically debuggers are language specific and won't be able to do both bash scripts and code in another language, but with this method, you should be able to figure out what's going on.
I am writing a small FLTK (GUI) program on windows 7 using Eclipse Kepler. My "int main()" function is not even set to receive any command line arguments, yet every time I build the program exe and run it a command line pops up being the GUI interface.
Does anyone know how to suppress this? I do not need a console display for any input or output etc. as this is all controlled via the GUI interface.
Thanks.
It has nothing to see with eclipse. It's a standard behaviour of c++ applications on Windows. Look for console on this page. You will find how to disable it.
i have this issue (https://github.com/sbt/sbt/issues/562)
basically when I try to get a console it says:
[ERROR] Failed to construct terminal; falling back to unsupportedjava.lang.IllegalArgumentException: Invalid terminal type: jline.UnixTerminal
also you cant use backspace
you basically cannot use sbt in cygwin (in dos is fine but cygwin is a much nicer environment)
and have voiced my concern there
i have tried several workaround i found on the net but they are all for old releases and no use now
was just wondering if you know of any workaround?
thanks
The following works for me (mostly, see note at bottom):
Use the mintty shell. I believe this is the default shell for new cygwin installs but has been included as an alternative for a while. If mintty.exe exists in your <cygwin home>\bin folder then it's ready to use, else it can be installed through the typical cygwin package selection from the setup.exe.
Open a mintty window, right click anywhere, go to Options... -> Keys, and make sure Send Backspace as ^H is checked. This will allow the REPL to correctly interpret backspaces.
For just running the Scala REPL that should be all you need, but attempting to run sbt console can still produce that exception. To get past that, run sbt without any arguments to get to the sbt prompt. From there execute:
eval System.setProperty("jline.terminal", "scala.tools.jline.UnixTerminal")
then
console
or, as a single command (with both semi-colons being important):
; eval System.setProperty("jline.terminal", "scala.tools.jline.UnixTerminal") ; console
From what I can tell, this is caused at least in part by the Scala REPL and the sbt prompt using incompatible versions of JLine. In particular, it looks like the Scala REPL created their own wrappers around the library and are using that while sbt is using the JLine library directly.
Note
One limitation that I continue to run into is that the REPL wraps at column 80 even if the shell window has more horizontal space. Not only that, but when the REPL wraps like this it overwrites the same line rather than advancing to the next, and pulling long lines from history ends up pushing the cursor above the line you're actually editing.
I am writing a Perl program that uses curses for output and move the cursor, and color characters. Previously, when I was working under windows I use Komodo it was able to run an external console.
Now I work in Linux environment and use eclipse + epic. If you try to just run the script, it uses the internal console eclipse, which is very cut. You can just run the script using external tool, but I'm interested to debug using external console window. Is this possible?
Unfortunately, use of a File and /dev/pty/1 does not help in solving my problem.
The fact is that in this case it is impossible to get the characters introduced in the console through curses getch(). Always returned 1 instead code of pressed key.
Here is an answer that will take you most of the way (based on post #6 of: http://ubuntuforums.org/showthread.php?t=743131, although since then, in the "Indigo" and "Juno" versions of Eclipse, things have changed somewhat, and this answer is up to date):
Go to "Run -> Debug configurations". Click on the (fourth) "Common" tab. Go to the third frame from top, and there, check-mark the checkbox which says: "File". Enter the file name of the console window you want your output in.
Is it possible to create a macro in Notepad++ that is able to utilize the "Run" command so that I may call an external .exe to operate on the file specified? I am able to do it manually, but when I create a macro that includes the run (F5) and give it a specified command it fails to execute. Is this because the run command isn't supported when creating macros? If so, is there a work-around method?
Thanks
edit: to add context -- I've written a couple ruby scripts to facilitate data-entry that's done using notepad++, and would like to integrate them to the editor. Having them run by a shortcut method created by recording a macro seems to be the best way to do this, unless it's not possible to utilize the run command.
FWIW The Zeus and Zeus Lite editors can do this.
You can do it with the NppExec plugin (available in the Notepad++ wiki ). It allows you to create mini-scripts with keywords that perform commands.
You will also be able to add your script in the contextual (right-click) menu, or assign a shortcut to it.
I personaly uses it to saves a sql file, place myself in the current directory, and then executes isql.exe (external executable) on that file. That simple script transforms my Notepad++ into a rather handy SQL IDE.
I don't think you do it using only Notepad++.
Please see this thread:

If I understood you correctly, you have it all set up but are having issues with running it through Notepad++'s run command?
If so, try what I mentioned here.
I had similar issues with running php compiler and resolved it with the "cmd /c" added like in that mentioned example. And a "& pause" at the end, just so I see what goes on.
