Wow you are flying along John, a coding machine!

The bundle post is nice too. Are you thinking of adding all the necessary dll's for the nimrod libraries into the distro folder John?

My effort was a temporary helper until you figure out what direction you're going with Nimrod. I'm an advocate just like you on the Nimrod project and counting on you taking the lead. Feel free to add to whatever you want to help the Nimrod project along. I find the language interesting and hope to pickup some tips from it.

John, I spent some time on the Nimrod site reading more in depth instead of glancing. It seems my bundle idea was really stupid ( about the dlls for the distro folder ). I see that they have many wrappers for various databases, scripting languages and the same for graphics and so forth, so it is not feasible or reasonable to do.

I think it is language worth keeping an eye on, but I don't think ready for prime time just yet. The forums and other learning material are good for introductory work, but for me not enough to do a bigger project.

I did a search for instance on a tutorial for Nimrod using sqlite3 and didn't find anything. With my poor memory, I need good references and tutorials to give me a start. Anyways I will finish the tutorials that they have and play with the examples.

I think I want to work on helping Charles get a front end for Oxygen. So I want to really get into gcc and its front end manuals and see if I can make a start for him.

Maybe you should start with ScriptBasic first before getting too frustrated with Nimrod.

I'm quite interested in the idea of multimethods, which seems to aggregate objects to a method, rather than methods to an object, (as in C style OOP).

It sounds like there are a number dependencies, requiring prior expertise to get Nimrod running though.

The Linux squeeze will continue to disable programmers that ignore the OS. Linux defines cross platform and the framework tools that are used. I highly recommend getting a FREE Cloud9 account and start honing your Linux skills before Windows as a development concept is no longer relevant.

John, have you tried Arch Linux? I tried to install it but didn't get to far, but in honesty, I tried it without looking at the installation instructions.

What I like about it is, once you install and get it setup, you never have to uninstall and reinstall a next version. It does continuing updates!

I found that Ubuntu does not come with lots of core programming things that are needed. I followed the lazarus free pascal Ubuntu install instructions and although I did each step and got no errors installing everything. When I went to run Lazarus, it gives me an error. 

Also, at least in Ubuntu, things are placed all over the place and many are protected for root and many operations you can't do.

My dream OS would be:
The OS is just an OS that you can get in 3 flavors. 1. Command line only: for servers and embedded devices. 2. Command Line with Ascii GUI: for people running servers and or businesses and want to keep employees from playing games. 3. A full OS with command line, command line and ascii GUI and regular modern GUI.

The system can't be touched by no one. It can only be updated from official servers or from dvd's from os source. It would be in its own partition and no access to anyone but from official OS sources.

Drive C: would be the users directory with each user being a root folder in the c root:

c:/kent
c:/john
c:/charles

When you log on as a user your root directory automatically is your directory. So if I log in as kent when I say cd /
it takes me into c:/kent
as kent I don't see any of the other users folders.

Only a root user can access any users folder. So some one logging in as root would see this when they type cd /
c:/kent
c:/john
c:/charles

Then there would be another partition that is shared data for all users this would be drive d:  for data :)

When I log in as kent, everything I do to the system settings configurations are stored in my folder that I have full access too.
all programs would be self contained in one folder for each program within a folder of the users choice.
Basically you allow the user to control where things are for their tastes and in naming the prefer. And each downloaded and installed packages would be in one folder and not put files all over the place.

Now the big thing. Each library that has a dynamic dll that is for a major project, submits their latest dynamic library and headers to the OS maker. They in turn in updates install these into the OS system.

For a dynamic library a user makes, that would be in their choice of how they want to store dll's and headers.

So basically all major projects and the operating system are taken care of for the end user and always up to date.

The last big things is that the OS can talk to new hardware, download the interface, dll and header to make that device work from the firmware of the hardware. So any OS designed with this interface to query and get stuff from the firmware can support the hardware.

Sounds like your talking about Cloud9 IDE. (and it's online and sharable)

Responses inline, I couldn't ignore this post... :-*

Most OS distributions are User-centric; if you want to develop on a given platform, you have to add support for it.

Also, at least in Ubuntu, things are placed all over the place and many are protected for root and many operations you can't do.

This is to protect you from yourself. ;D  It's real easy to destroy a system otherwise.

A full OS with command line, command line and ascii GUI and regular modern GUI.

Most Unix-like OS's already provide 1 and 3, while 2 reminds me of Linux in the late 80's.  As an aside, without a modern GUI most end-users would not be inclined to play games.  :)

Sounds like you want Debian.

That would end up being an administrative nightmare, I think.

it takes me into c:/kent
as kent I don't see any of the other users folders.

When you log on, or start a terminal from a GUI session, you are already in your home folder. 

If you're somewhere else in the file system, "cd" by itself takes you back to your home folder.

Quote
Only a root user can access any users folder. So some one logging in as root would see this when they type cd /
c:/kent
c:/john
c:/charles

Not sure what the advantage to this would be over doing "cd /Users" (if supported) or "cd /home".  In your example, you would also see all of the folders/files that are at the root:  /bin /sbin /home /usr /etc

Quote

Very easy to do if your partition your drives and edit /etc/fstab

When I log in as kent, everything I do to the system settings configurations are stored in my folder that I have full access too.

In Linux, a user's home folder generally has a hidden folder called ".config"

In it, you can over-ride most system-wide settings.

Basically you allow the user to control where things are for their tastes and in naming the prefer. And each downloaded and installed packages would be in one folder and not put files all over the place.

This would lead to tremendous duplication on a multi-user system.  For example, say you and I use the system.  We both want to use OpenOffice.  In your scenario, we each would have our own copy in our home folders.  Come update time, if it's automated, the system would have to upgrade each copy.  If it's not automated, each user is responsible, which now involves downloading the update twice.  Pretty soon, we'd be fighting a drive-space issue.

Quote
Now the big thing. Each library that has a dynamic dll that is for a major project, submits their latest dynamic library and headers to the OS maker. They in turn in updates install these into the OS system.

That's sort of what happens now, if you think about it.  Keep in mind, thought, that all sorts of regression testing has to take place, which is why all distro's may not have the latest and greatest SW/Libraries available.

Quote
For a dynamic library a user makes, that would be in their choice of how they want to store dll's and headers.

Then you would have to contend with additional compiler and linker switches, so that your software can find the libraries and headers.

Quote
The last big things is that the OS can talk to new hardware, download the interface, dll and header to make that device work from the firmware of the hardware. So any OS designed with this interface to query and get stuff from the firmware can support the hardware.

Hardware is proprietary; it falls to the hardware producer to create the drivers for a given OS.  How would you even begin to manage that, since most Linux distributions aren't heavily funded?

Even Microsoft can't do this 100%; it's a logistical and monetary nightmare.  Sure, you can go with reference drivers released by the manufacturer, but you would probably want to go with what the Vendor provides instead.

Take Graphic cards, for example.  A Vendor may have added an enhancement that the reference drivers don't support.  So now, using ATI as an example, you have to provide drivers for just about every conceivable Vendor implementation. 

All in all, your ideas are interesting, but (just my opinion) they aren't practical.

Nimrod - nimgame
« Reply #56 on: October 08, 2013, 12:08:51 AM »
nimgame

Simple 2D game engine for Nimrod language.

This is a Babel installed library. I have posted the API docs HERE.

UFO Attack nimgame API Windows example.



Code: [Select]
import
  sdl, math, common, state, entity, image, imageex, sprite, text, input, engine, collider,
  ufoattack_player, ufoattack_ufo, ufoattack_stars

type
  PGameState* = ref TGameState
  TGameState* = object of TState
    player: PPlayer
    score: PEntity
    addStarCounter, addStarInterval: int
    addStarIntervalMin, addStarIntervalMax, addStarNum: int
    addUfoCounter, addUfoInterval: int


proc free*(obj: PGameState) =
  PState(obj).free()


proc init*(obj: PGameState) =
  obj.player = newPlayer(obj)
  obj.add(obj.player)
  obj.score = newEntity(newText("fnt/DejaVuSans.ttf", text="0",
                                size=18, color=color(250, 250, 0)),
                        2, 580)
  obj.add(obj.score)
  # stars
  initStars()
  obj.addStarCounter = 0
  obj.addStarIntervalMin = 10
  obj.addStarIntervalMax = 30
  obj.addStarInterval = random(obj.addStarIntervalMax - obj.addStarIntervalMin) + obj.addStarIntervalMin
  obj.addStarNum = 3
  for i in 0..50:
    addStar(random(screen().h))
  # ufo
  obj.addUfoCounter = 0
  obj.addUfoInterval = 50

proc newGameState*(): PGameState =
  new(result, free)
  init(PState(result))
  init(result)


# Update

proc updateGameState*(obj: PGameState) =
  obj.updateState()
  # Stars
  if obj.addStarCounter >= obj.addStarInterval:
    for i in 0..random(obj.addStarNum):
      addStar()
    obj.addStarCounter = 0
    obj.addStarInterval = random(obj.addStarIntervalMax - obj.addStarIntervalMin) + obj.addStarIntervalMin
  else:
    obj.addStarCounter += 1
  updateStars()
  # Ufo
  if obj.addUfoCounter >= obj.addUfoInterval:
    obj.add(newUfo(4))
    obj.addUfoCounter = 0
  else:
    obj.addUfoCounter += 1
  # Collide
  if obj.collideWith(obj.player, "ufo") != nil:
    obj.player.delete()
  let collisions = obj.collideList("shot", "ufo")
  for pair in collisions.items():
    pair.a.delete()
    pair.b.delete()
    obj.player.score += 10
  # Update score
  PText(obj.score.graphic).text = obj.player.score.repr
  # Toggle FPS
  if isKeyDown(K_f):
    if game.fps:
      game.fps = false
    else:
      game.fps = true

method update*(obj: PGameState) {.inline.} =
  obj.updateGameState()

# Render

proc renderGameState*(obj: PGameState) =
  blitStars()
  obj.renderState()

method render*(obj: PGameState) {.inline.} =
  obj.renderGameState()

Nimrod - Inline ASM
« Reply #57 on: October 08, 2013, 02:01:31 AM »
Assembler statement

The direct embedding of assembler code into Nimrod code is supported by the unsafe asm statement. Identifiers in the assembler code that refer to Nimrod identifiers shall be enclosed in a special character which can be specified in the statement's pragmas. The default special character is '`':

Code: [Select]
proc addInt(a, b: int): int {.noStackFrame.} =
  # a in eax, and b in edx
  asm """
      mov eax, `a`
      add eax, `b`
      jno theEnd
      call `raiseOverflow`
    theEnd:
  """

I would think that Nimrod would be a much better language for Charles to use for OxygenBasic. He could use Nimrod to handle the platform specifics while he gets cross platform ASM code stable. The C emitter is already done for him.

Other libraries

I found today while researching that other libraries(wrappers) do exist for Nimrod that are not listed in their list.
So something to keep in mind, if there is a library you would like to use that is not on the list.
The current list: http://nimrod-code.org/lib.html

Here is one I found today:

Here are a couple screen shots from their included demos. I had to install an older version (1.5 / current 1.6) of GLEW to get it to run.
