mailing-list for TeXmacs Users

["Adrian S." <address@hidden>]

Thank you, Joris.  I originally wanted this to be able to emulate EOF when newlines were not transformed into spaces so that the plugin would know when the entry of the user has ended.  In the modifications I gave this is worked around, and I did some guessing, since I still don't quite understand the serializer.

As far as I am concerned, it is no longer a priority for me to have that fixed, as I found a reasonable alternative, though this poses a problem in the documentation of features that are not available.

The fix to have all plugins compile was a long needed one, since they are the models people will follow to write new plugins.

Thank you, Joris!

Peace.

-Adrián.

Dear Adrian,

Yes, you are right: the multiline feature no longer works.
This is a consequence of the latest "improvement" of the plug-in system,
which now allows for the execution of several inputs in succession.
If I have some time, then I will try to fix this issue, but this is
not completely trivial.

Best wishes, --Joris

PS: I did fix the compilation issue concerning iostream.h;
also for the other example plug-ins.
