[gnotepad-users] gnotepad+ 1.3.0pre4 (April-25-2000) - some thoughts

[Dermot M. <de...@gl...>]

Hello everyone,

I have just been trying the latest gnotepad and it seems way, way better
than when I tried it some time ago - thanks for all your work Andy.

Some things came to mind while editing some HTML - in no particular order.

1) The 'Apply' button in the Preferences dialog did not apply the changes
and I had to restart gnp to make changes (eg the editing font) happen. 
This was the first time that I ran gnp and it seems OK now.

2) The GtkXmHTML (doc) does not reflect unsaved changes made to the HTML
even though the GtkXmHTML (window) seems to.

3) Undo stops working after inserting from the HTML menu (eg Title).

4) I could leverage all your good work in a little app that I am writing
if I could tell gnp to open another document (tab). I realise that I can
start a whole new gnp each time but I think that it would be cleaner to
have all the open docs available in one place.

5) Is it possible to show the full path name of the documents somewhere?
Either a tooltip over the tab label or a status bar message would be good.
Also the recent files menuitems (or a tooltip?) - I get lost with 6 files
called 'index.html'.

6) I have seen this warning several times - I don't know when.
  Gtk-WARNING **: gtk_signal_disconnect_by_func(): 
    could not find handler (0x8053F50) containing data (0x81C9380)

7) I have seen this - again I don't know what caused it:
  GLib-CRITICAL **: file gmain.c: line 500 (g_source_remove): 
    assertion `tag > 0' failed.

8) What about a simple signal handler for a GtkXmHTML (doc) 'activate' to 
load and raise the clicked URL (if it is a local HTML file)?

9) I know that syntax highlighting is a lot of work to achieve but I have
done some HTML pseudo-highlighting (in perl) with the sub below. Perhaps
it could be a user option although I don't think that this trivial tag
highlighting is very expensive. Still it might need another couple of user
preferences (HTML_tag_color and HTML_comment_color) to be really friendly.
Please excuse my bad coding style - and also that it's in perl :) 

I don't know C but I guess that this approach would map fairly well. I only
re-show the HTML on a notebook page switch or a user-request but it seems
pretty snappy on small files.

BTW perl's index looks in a string (eg $html) for a character (eg '<'), 
starting at offset (eg $pos) and returns the new offset if found or -1.

sub show_html {
    my ($class, $textbox, $html) = @_;
    my $pos = 0;
    my ($tag, $prev_contents);
    my $new_pos;
    my $cm = $textbox->get_toplevel->window->get_colormap;
    my $plain_color   = $cm->color_alloc({red=>0, green=>0, blue=>0});
    my $tag_color     = $cm->color_alloc({red=>0, green=>0, blue=>65535});
    my $comment_color = $cm->color_alloc({red=>65535, green=>0, blue=>0});

    my $plain_font = Gtk::Gdk::Font->load(
        '-b&h-lucidatypewriter-medium-*-*-*-*-120-*-*-*-*-*-*');
    my $tag_font = $plain_font;
    my $comment_font = $plain_font;
    
    $textbox->freeze;
    $textbox->delete_text(0, -1);

    while (($new_pos = index($html, "<", $pos)) > -1) {
        $prev_contents = substr($html, $pos, $new_pos-$pos);
        $pos = $new_pos;
        $new_pos = index($html, ">", $pos);
        $tag = substr($html, $pos, $new_pos-$pos+1);
        $pos = $new_pos+1;
        
        $textbox->insert($plain_font, $plain_color, undef, $prev_contents);
        if ($tag =~ /^\<\s*!--/) {
            $textbox->insert($comment_font, $comment_color, undef, $tag);
        } else {
            $textbox->insert($tag_font,     $tag_color,     undef, $tag);
        }
    }
    $prev_contents = substr($html, $pos, $new_pos-$pos);
    $textbox->insert($plain_font, $plain_color, undef, $prev_contents);
    $textbox->thaw;
}    

Apologies for the long posting and thanks again.

Regards, Dermot.
