#6194 — Some questions about developing for RISC OS

Dear c.s.a.p,

First question [and it maybe obsolete by the time you read this] is
about the DDE.  I just sent a payment to ROOL (?) but did not get
an immediate download link.  Is this normal?  I believe I bought the
.zip download /only/ but I have no records of what exactly was bought
[yet.]

What is a good way to get started with programming for RISC OS?  I used
to have an emulator with RISC OS about a decade or more ago, and back
then I played a bit with GCC, but never got really far, and I've pretty
much forgot /everything/.

For the record, I'm already proficient with C, C++, and other languages
and operating systems, including Posix.  ARM and RISC OS are new to me.

I guess I'm going to need some hand holding with day to day operations,
and read the user's guide, and that's ok.  I'll try to keep user
questions to c.s.a.misc though.

What do people /need/ for RISC OS?  Where would my programmming efforts
be mostly helpful?  I know what /I/ want to do, which may be completely
irrelevant to everyone else; so I make no promises on working on any-
thing in particular.

What are people willing to /pay/ for?  If I can get my employer on board
and sell some software, then we'd be discussing a lot less time to
delivery than if I only work in my free time.

Thanks,
--

Hope you received it, if not check it is not mistaken for spam by your

It took a few hours, but I eventually got a receipt from Paypal, that I
paid for [DDE Zip Download] but so far, no email from ROOL that I can
tell, nor anything in my spam folder.

Am I supposed to get a download link in email?

I'll wait a few days before I try emailing ROOL.

Yes, you get a link by email. However, everything is done 'manually',
including giving you a DEV number, and also hardcoding your ID into
the compiler binary, so it can take a couple of days to receive the
link.

Indeed, I got my link and dev id.  I asked the installation question
in c.s.a.misc; it's a bit terse for someone brand new.

Where does your interest and skill set lie?

There's various points in the stack you might start:

Desktop apps: C, C++, BASIC are popular.  Other languages like Python and Lua are
a bit more niche (and more likely support is a bit more patchy)

(User-facing) Modules: filesystems, system services, drivers.  That's mostly C (or
assembly, for the masochists).

Operating system: modifying deeper level stuff, porting to new hardware: C
or assembly.


The DDE is needed for actual OS development, but its C++ is ancient and the
tools can be a bit quirky (there's a Make but it's not GNU Make, for
example).  GCC has good C++, shared library and cross-build support but
isn't supported for building the OS.

If you don't get answers here, the ROOL forum is also worth posting to.
(many only read one but not the other)

https://www.riscosopen.org/bounty/
https://www.riscosopen.org/forum/forums/2

There is typically a skills disconnect between people who can, say, debug
the USB stack, and developers who work on application code in BASIC.  This
is why many bounties are slow to be taken up.

The usual problem is the market size.  People sometimes wave cash around
('I'll pay £50 for X') but if only three of them want it, it's not cost
effective.  I'm not sure any RISC OS project is cost effective in terms of
commercial rates.

If any of the bounties work for you, that could be a place to start.

You could also ask if there are starter projects you could try.
(many open source projects have them, but ROOL hasn't traditionally)

If you have time you could commit, it could be worth talking to someone like
R-Comp to see what they see as pressing needs.  They probably have more
contact with real customers than most.

All over the place.  I have a history of contributing to a wide variety
of projects, both as part of my work, and in my free time with open
source projects.  My project history includes device driver code, though
what I can show would be software only projects [on my blog] for OS/2
and Illumos [formerly OpenSolaris]; database code, server plugins for
Postgres, SQL clients, and such things; some graphical and desktop
applications; and a whole bunch of other stuff.

That would make me a Jack of all trades, so to speak.

A desktop app is something I might do as practice.

This would also be high on my list of interesting things.

This might also interest me, though it would probably depend on the
scope of any individual project.

I tend to prefer C over C++ these days, and I try to avoid GCC when I
can, for my own reasons.  That's why I went for the DDE to begin with.

Thanks.  Right now I'm one of them [posting here, not reading the
other.]

I think the bounties and wish lists are something I'll look at more when
I've gotten some RISC OS experience.

The bounties /may/ work, but I'll not start out with them.

What do you mean with a starter project?  I'm not familiar with the
term.

Thanks, I'll keep it in mind when I have some experience to show.

That sounds like a good fit for RISC OS :)

RISC OS is simpler than most popular OSes today, so you can have more
breadth across different areas.  Whereas in say Linux there's so much to
learn you can only really focus on one part.

It's a good starting point.

It could be worth looking at, say, the git client as an example of something
that the community needs, and that could be done by someone with an
application-focus (ie no deep OS plumbing experience).  You might not be
claiming the bounty as such but could provide a concrete project to think
about.  It touches a number of cross-cutting issues (porting 'foreign' code,
keeping it maintainable, interfacing with the filesystem, making both
command line and desktop apps, etc).

Many open source projects have enormous codebases.  A beginner is utterly
overwhelmed by how much code there is, and where to start understanding how
it works.  A starter project is something that the community wants that can
be done by someone who is not very familiar with the codebase.  The
community gets the job ticked off, and the contributor learns how everything
fits together by working on the codebase.

'Google Summer of Code' is a programme that encourages new (student)
contributors, and GSoC projects are often designed in this kind of way, that
a new person can do in a few months of full-time work.  The lists of GSoC
projects are often good starting points.  Often OSS projects also have
starter projects that are much lighter than that - can be done in a few
dozen hours by a new contributor.

RISC OS doesn't have that kind of programme, but it could be worth asking
the ROOL forum to suggest such projects.
(although be aware there's a minority on the forum that can be quite vocal
about what's - and what's not - important to them)

Welcome Johann, always good to see new programmers here, RISC OS certainly 
needs them!

Steve Fryatt has lots of useful stuff on his site, including an excellent 
Wimp programming in C tutorial:

http://stevefryatt.org.uk/risc-os

For an emulator, download RPCEmu here:

http://www.marutan.net/rpcemu/easystart.html

As others have mentioned, most RISC OS developers hang out on the ROOL 
forum, and there's documentation on their wiki too:

RISC OS is very much NOT posix, so prepare to learn whole new ways of 
doing things!

You'll be much more productive on things you're insterested in, so just 
have fun tinkering and see where it leads you :-)

The market is very small, so you'll never get enough income for commercial 
programming rates, but might manage some beer money!

You could also contact the Cloverleaf project as they have plans to pay 
for some app development:

[Answering this months later.]

Yes, I've been through that culture shock before, when I dove into
OpenVMS.  RISC OS is not only /not/ Posix, it's also /not/ VMS, /nor/
is it DOS/OS/2/Windows either.

The User Guide that comes with the system is nice, but a little bit
long to read, for people who come to the system from elesewhere, and
need a /what's different/ guide more than a total newbie guide.

If there is a /what's different/ guide out there, I have not come
across it.  Maybe I'll try to write one, or maybe not.  It shouldn't
be hard to write, but needs to focus less on the GUI which is easy
enough once you know there's a menu button, and more on what characters
are valid in file systems, what the separator is, what the character
for /previous directory/ is, what *commands are; and so forth -- in my
opinon.

[I'll consider answer the other points later on, when I have more
programming experience under my belt.]

The GUI was the selling point for RISC OS, which wasn't really targetted
at command-line programmers - most users today probably don't have the
faintest idea what the character for 'go up a directory' is, and few of
them type in anything other than a leafname, since all files are
normally saved by drag and drop from a 'savebox' and the destination
directory is selected visually.

Knowledge on that level ceased to be important to the general user once
the days of the BBC Micro were over.  (I think the RISC OS 2/3 User
Guides may contain more useful stuff about 'star commands' and system
variables than the later ones, which is why I hung onto mine.)


But a "what's different" guide from the *programmer's* point of view
would be potentially a very useful resource - you really do need to be a
new user yourself to know what is non-obvious to new users and what the
important bits of information are.

One command line thing dating back to the BBC Micro caught out a new 
user recently. They found that doing a *Help Commands in a graphic task 
window or bash window would grind to a halt stop and lock up the 
desktop, but it wasn't a bug.

This is down to paging mode, first seen on the BBC Micro, where the OS 
would stop after each screen full of output, so you could read it, and 
you then pressed shift to show the next page. This is similar to the 
Unix more or less programs, but with one crucial difference - there is 
no indication on screen that you need to press anything to continue.

Normally page mode is only invoked outside the desktop or from the F12 
prompt, it's not normally supported by taskwindow handlers such as Edit 
or Zap. But !GraphTask, and it seems bash, do pass the Ctrl+N code which 
enables paging to the VDU system. I did think of disabling it, but then 
having the output pause in a graphic task window is still useful, as it 
doesn't have any scrollback capability.

I'd forgotten the Beeb did that. Maybe someone could write a module to 
illuminate scroll lock light in paged mode, as this feature is an auto 
scroll lock. Although I see a lot a keyboards now leaving out the scroll 
lock light.

Just to add there's a new thread on this on the ROOL forum - it's good at
going into the pros and cons of various approaches:

Dear c.s.a.p,

Life happened and I had to put RISC OS programming on hold for a
while.  I've now installed the DDE and successfully compiled some
sample code, as covered in the README.

I am using DDE 30, as updated a few days after I bought my copy.

When I originally emailed ROOL to subscribe to my yearly updates,
I got an error message, as that email address seems to be non-
functioning.  I don't know if this is automated now, or if it's
just because the updated came so shorly aftewards that they decided
to email me with it anyway.

What is the proper way to contact ROOL about this?

Side question: should I keep my developer ID secret?

A question I had in the bounced email, was

 >> OTHER NOTES
 >> We suggest you use the official RISC OS build environment rather than
 >> tools such as !Make (which is still included as a legacy option).
 >>   https://www.riscosopen.org/wiki/documentation/pages/Technical+notes

so there seems to be a discrepancy between the email advice and the
wiki.  I'll repeat that I don't know what ROOL is trying to tell me.

I also noticed that I have a /lot/ to learn about RISC OS itself.
The provided User Guide is nice, but if anyone has written a short
document on getting up to speed with RISC OS when coming from another
system[1], I'd welcome it.

As others have pointed out, the webforums are a nice resource, and I may
move my questions to over there; or duplicate them here.  I also have
some user questions, for which I'll stick to the non-programming groups
for now.


[1] I am familiar with most other current systems, for some value of
/current/.

There's a contact email given in the documentation, I think. That said, ROOL
are a "spare-time" operation, so often asking in the ROOL forums is the
quickest way to get an answer.

That seems wise.

Only in the sense that the page has been split into separate sections for
programming (in all the senses) and extra stuff related to developing
RISC OS itself. It was getting confusing before, IIRC.

In the quote above? Simply what they say: don't use the Make application,
which is a legacy thing; use Amu, which is more like what Make is on other
systems.

Also, use the project templates and Shared Makefiles (which are powered by
Amu) for new projects when possible, as they're far easier to maintain. In
and amongst the other stuff, there's some info on Shared Makefiles here:

Hmm, ok.  At least for people who websearch, they might benefit from a
recap there.

Thank you.  I used these instructions to type in and compile my own
hello world; I copied over the Makefile and Obey scripts.

I had previously run into the dreaded DDE30 bug described here.

   https://www.riscosopen.org/forum/forums/4/topics/15809

There is no open bug report about it, so I have no idea if it's been
fixed by now, that I found.
