MuView

[Chris Newman]

Hi,

Raspberry Pi4 RISC OS 5.28 running Pinboard 2 (dec 2022)

I have !MuView by Chris Grandsen.

it's not in the !Boot look at list. !PDF 3.02.1.24.1 (March 2017)by
Grandsen, Granville, Smiers 7 noonburg is in the look at list.

However, every time I look at a PDF it loads !MuView, not !PDF.

I've used Textseek to look in !Boot to see if I can find a reference
to!MuView but the only 2 are the listing in Pinboard 2.

It doesn't appear in Resources.

So why / how has !MuView set itself up as the default?

It's a great app and I use it a lot but you can't print directly from it
whereas you can from !PDF. Therefore, I want to be able to choose easily
which app I use.

Any thoughts?

Open up the !MuView App with Shift+DoubleClick and look into the !Boot
Obeyfile. Eventually there is a line with a "***@RunType ..." command
in it. If so - outcomment this line with an "|".

Is !MuView in a *directory* that is in the Boot at Startup list?
Resources or Utilities for example.

If not, then if you run Reporter from Boot you can search for MuView
and see when it is referenced.

Unless I have read your posting incorrectly you are using pinboard2 ?
My understanding is the new Pinboard treats the contents like any other
filer window. In which case I would expect !Muview's !boot file to be run
when Pinboard 2 starts up.

Try taking !Muview out of the pinboard and rebooting. What happens then?

Well, dash my buttons. You're right sir. That did the trick. Obviously I
didn't read the Pinboard 2 idiots guide thoroughly enough.

I've just had a look at the only Help file I can find in the Pinboard
download. It's a bit sparse. Under "Goals" we get "Allow filer-like
operations" but whether that is for the future or already implemented I
know not.
I can't find a way to turn off the running of a !Boot file so it looks as
though I'll have to put !MuView in my launcher (NeXTBar - Paul Vigay) for
ease of access instead of the pinboard.

As mentioned above - You can modify the !Boot file ... and it can hold
its place on the pinboard.

Better still, just ensure that the preferred PDF reader is booted first.
Applications shouldn't claim an already claimed type on being seen by the
Filer.

Editing parts of an application is always a pain when it comes to doing an
upgrade (or asking the author for support).

I agree,
!PDFTest and !Muview , in that order, are added to my Apps folder and no
problems.

I have to admit that my response was sort of gleaned from various places -
as you say the help file, is lacking at the moment. The ROD page for the
app is more helpful in it's description and capabilities. I suspect what I
half remember comes from a talk from either Andrew or Richard.

As the contents are now stored in a normal directory the new module must
do some sort of filer_boot type command.

As has been pointed out just commenting out the lines in the boot file
will overcome the problem.

I can see no evidence that Pinboard2 will boot anything - can Chris
clarify exactly where in Pinboard2 there was a reference to !MuView,
and what evidence is there that it runs the !MuView !boot file?

I am intrigued if I am being blind!

The !Muview claimed the filetype whilst it was on the Pinboard, and didn't
when removed from the Pinboard would suggest that the module does run the
boot files of any apps.
The new pinboard is not like v1 which you have to physically save after
every change, it is dynamic, much like the rest of the filing system. The
new version is much more like windows in that when something is saved to
the desktop it actually sticks the file into a directory for later
retrieval. This fits in with the statement to make it consistant with rest
of the filing system. As I have said in a previous post this is my
understanding based on what I have seen and heard.

boot files of any apps.

The source code is a little impenetrable and not that well commented, but
there's an fs_boot_application() function in fs.c which appears to boot an
application, and it *appears* from a very cursory look to be called when
things are pinned to the pinboard using *Pin and *XPin.

This is actually a fairly common problem with application launchers, as an
application needs to be booted, or at the very least have its sprites passed
to *IconSprites, in order for its icons to look correct when the launcher is
viewed by the user. In Launcher I offer the options of "Boot", "Load
sprites" or "Do nothing" for precisely this reason (and "Load sprites" would
be the one that Chris would want to apply for MuView).

So, yes, I think that apps pinned to Pinboard 2 will probably be booted. As
I said, I could be wrong. I don't (yet) use Pinboard 2.

If both apps are on the new pinboard, it looks as if another solution for
Chris might be to ensure that in whatever configuration file is being
created, the *(X)Pin command for PDF appears before the *(X)Pin command for
MuView. As far as I can tell, Pinboard 2 boots things in the order that they
are added to the backdrop.

Thanks John & Steve: I was obviously having an aberration and missed
the obvious %Run <appname>.!Boot commands being run, in the order of
the Pin commands in Tasks.Pinboard - which seems to be order of
adding.

The !Boot is required, as Steve says, to do the IconSprites command so
the icon can be displayed.

Interestingly, Pinboard2 creates an alias for IconSprites:
Alias$IconSprites : Pinboard_IconSprites %0
and then Pinboard2 then does
%IconSprites <filename>

I had taken MuView off the Pinboard, saved the new pinboard and
re-started the machine.

Now I'm back to !PDF being the default.

In order to show the type of thing I'd discovered earlier, I did a
Textseek search on !StreetFix whichis still on the pinboard. Got
references to it as expected. Then I did a search on MuView expecting
nothing to show but see below.
