[Octave-bug-tracker] [bug #54053] "doc persistent" should work in GUI as it does in CLI

[Rik]

Follow-up Comment #7, bug #54053 (project octave):

It turns out that doc.m has two very different paths.  If the CLI is running
then the m-file calls out to the external info program to search its indices
and return a match node.  When the GUI is running, Octave calls accross to the
Qt thread using __octave_link_show_doc__.  The code is more complicated
because it is in C++ and is making use of Qt documentation widgets.  It
appears that instead of searching the GUI just attempts to open a node of the
given name.  There is a search capability present in texinfo-parser.cc
(find_reference).  It might be possible to hook that routine up somewhere
along the line.
