No one was ever able to reproduce this, and it looks like the OP account has been deleted, closing.

Retagging release from 4.0.0-rc3 to 4.0.0.

Replying to the questions:

1. About re-activating the "editor", I have tried from the menu: "Window/Show Editor" and "Window/Editor (Ctrl+4)" and the editor does not re-appear. All other windows re-appear normally if close them down. What I mean by closing the tab of the editor is a) closing all the open files in the editor and b) closing the editor window itself also, leaving open alone the command and documentation-windows (having closed also the rest of the windows: workspace, command-history, file-browser, etc).

2. About the file "built-in-docstrings", I search with the command:
find / -name "*built-in-docstrings*"
and it finds only a file for octave 3.8.2 which have also installed (from rpm). I am sure though that after installation I got a glimpse of the help menu (different from the incorrect one that shows now) and afterwards it disappeared. Looking in my notes, I noticed that had installed octave-rc3 from the source with:
a) ./configure --without-curl --disable-docs
based on a web link suggestion with which I solved the configure error that I was getting with "./configure":
configure: error: A BLAS library was detected but found incompatible with your Fortran 77 compiler settings.
b) make CFLAGS=-O CXXFLAGS=-O LDFLAGS=
c) make install

Probably the configure option "--disable-docs" is the reason for the missing help.

3. About the "a" in the command-line, surprisingly it does not complain for "undefined". I tried "b" and other letters and it complains. Otherwise Octave is working without problems (please see attached image "command_window_01may15.png").

About the "clc" that does not work, I did not use "--disable-readline" in the ./configure, and "--enable-readline" is on by default (see bug #29804).

Issue 1)

Did you close the editor window tab completely?  To re-enable it use the Window menubar option.  See the attached screenshot.

Issue 2)

How did you build and install Octave?  Was it a download of the rc3 tarball and then './configure; make; make install'?

It seems pretty clear that the reason no documentation is displayed is because the file is missing for some reason.  In my installation there is a file '/usr/local/share/octave/4.0.0-rc3/etc/built-in-docstrings'

Issue 3)

Is Octave working at all?  Looking at the screenshot, after you typed 'a' it should have responded with


error: 'a' undefined near line 1 column 1


Try something simple like


x = 2 + 2


and see whether you get anything back.

After installation I used the editor of the GUI once and then closed its tab. I try to open it again but it does not appear any-more.

"Closed its tab" means you closed all tabs and got an empty editor window or you closed the whole editor window?

warning: docstring file '/usr/local/share/octave/4.0.0-rc3/etc/built-in-docstrings' not found

This means that the documentation is not installed correctly. But this in turn would mean that the documentation window always was empty in 4.0.0-rc3

The command "clc" is not working

Works for me (ubuntu 14.04 64 bit)

ISSUES:
1. After installation I used the editor of the GUI once and then closed its tab. I try to open it again but it does not appear any-more.

2. Likewise the "Documentation" window was displaying the related info after the installation but now probably after I closed its tab, it shows incomplete information. In the command window there is a warning upon loading Octave:
warning: docstring file '/usr/local/share/octave/4.0.0-rc3/etc/built-in-docstrings' not found

See attached images: documentation_window.png and command_window.png.

3. The command "clc" is not working. It works though in Octave 3.8.2 which I installed from a rpm. The Octave 4.0.0-rc3, I built from source.
I looked at: "bug #29804] Clear Screen Function not working" and says the built to "include support for readline command" but it is not obvious how to do that.

PS.

Operating system: Scientific Linux 6.6, 32-bit.
