address@hidden: info-lookup-symbol]

[Eli Zaretskii]

The message below was posted to help-gnu-emacs.

The problem here is that makeinfo disambiguates identical index entry
in a way that leaves the entries qualified with <N> first in the menu
it generates for the Index nodes.  The relevant excerpt from index.c
is this:

      /* Fix entry names which are the same.  They point to different nodes,
         so we make the entry name unique. */
      if (copy[i+1]
          && STREQ (copy[i]->entry, copy[i + 1]->entry)
          && !html)
        {
          char *new_entry_name;

          new_entry_name = xmalloc (10 + strlen (copy[i]->entry));
          sprintf (new_entry_name, "%s <%d>", copy[i]->entry, counter);
          free (copy[i]->entry);
          copy[i]->entry = new_entry_name;
          counter++;
        }

How about if we change this to modify copy[i+1]->entry instead of
copy[i]->entry?

(The real solution to the problem described below is to fix the
offending manual not to have identical index entries, but that's
outside of Texinfo's control.)

Subject: info-lookup-symbol

Hello,

when I use info-lookup-symbol, I sometimes get to the wrong place in the 
info file. For example, when I use info-lookup-symbol on the keyword 
"break" in a Python source code file, it takes me to the index item

* break <1>: try statement.

instead of

* break: break statement.

probably because (strangely) the first appears before the latter in the 
index of the info file. How can I avoid this? Is it, for example, 
possible, to get a summary of all index items that contain "break" 
instead of directly jumping to the first one? Also, how does Emacs know 
in which index file to look / how can I customize it?

Regards,
Rehceb Rotkiv
