Context senistive help for c/c++ if using Cygwin? [message #175034]

Hello,

is it possible to get a context sensitive help in CDT like in java?
If I hover "System.out.println();" in java I get:
void java.io.PrintStream.println()
Terminate the current line by writing the line separator string. The line
separator string is defined by the system property line.separator, and is
not necessarily a single newline character ('\n').

Carsten,

CDT does not have this sort of "documentation hover" out of the box. You
could supply your own help provider but that takes writing your own plug-in
with the right extensions and Java classes. (Ask me if you want more
information ...)

Cheers,

Norbert

I don't think that I could do that.

Carsten,

this is not only a question of maturity but also a question of who has
authoritative documentation of the C/C++ language and the standard libraries
and is willing to publish them under the eclipse license. There was an
interesting post in thread "Re: C++ Language Reference within CDT" on
2006-08-22 about such online documentation.

(see message id <d75d78ec7158bf696941cef3d3cc323a$1@www.eclipse.org>)

Cheers,

Norbert

Why should this matter?
It should be extracted from the original documentation of the used
compiler.
The ISO-Standard-help would be little bit to few.
No POSIX, no windows-API etc.
Problematic are third party classes because their is no defined helpformat.

What you suggest is clearly a copyright violation of the material from
the "original documentation of the used compiler."

http://en.wikipedia.org/wiki/Copyright_violation

If the license holder of the original compiler contributed this
documentation to the CDT under EPL, then this feature would be possible
-- otherwise there is little chance of it happening.

No.
It should not be copied and distributed with CDT but extracted in realtime
like with java.

Maybe we can use the "man pages" as a reference for system and library
calls. Also, I know vim has a plugin that comes with C/C++ reference.

Ashish,

I think your approach is valid if man is called in the background and it's
output is reworked in an eclipse plugin to become a html help page. This is
because calling a tool and using it via a pipe is allowed by the GPL.
On the other hand it would not be allowed to package the man documentation
files inside the plugin and extract the information directly.

Actually I have thought of creating such a man page help provider but have
not yet found the time. I think that man based help is pretty generic and
available on most platforms. Any volunteers? Post suggestions to cdt-dev,
create a bugzilla and submit your patches. I'll evaluate them and commit
them if they are good :-)

Similar thoughts are valid, e.g. for .chm help provider ...

Cheers,

Norbert

Exact that is my idea, I didn't explained ist good. But maybe not calling
the command "man" but building a manpage reader for CDT.
