Sure, although the backwards naming of components something that is

Then what _is_ the recommended directory structure?
You'll find that a lot of folks use one the following, starting from the root

src/AssemblyName/Namespace/Namespace/Namespace/Class.cs — nested namespaces,
rooted by assembly
src/AssemblyName/Namespace.Namespace.Namespace/Class.cs — top-level namespaces,

Thanks, your help has gotten me past my original hurdle, but,
is this kind of stuff documented anywhere? or is it just
something you have to figure out and/or ask about like I did?
I think 'man gmcs' may have some examples. It'll definitely have documentation
of all the command line switches that you need/want to use.
In a related question... how would I go about compiling the components
separately and then 'link' them together into a library? (ie. the traditional
'don't recompile unless the source file changed' approach.)
You don't (well…mostly. Netmodules exist, and I'll address them shortly). The
C# compiler is plenty fast, so there's generally no need to do this. It's not
like the C++ compiler, chewing through 450k of headers and source for Hello,
world! That said, there is an intermediate format called a netmodule, but it's
poorly documented because Microsoft has more or less dropped support for them.
They can still be accessed via the compiler directly, but none of the IDE's
support using them. I'm also not sure of the limitations—more likely than not,
you can't go single .cs file to single .netmodule because you need to resolve
all the referenced types at emit time.
This would all be much easier if you were using MonoDevelop rather
than working at the command line, but I suppose you're like me and
want to do it the hard way first. :-)
Your right. I'm an engineer and not a 'mouse jockey', and I need to know
whats
going on. Especially because I can't expect the 'next guy' to be using
exactly the same tools (or platform) as I am. Heck... I didn't even know
that MonoDevelop existed! None of the introductory docs _I_ read mentioned
it.

MonoDevelop was at one point referenced from

Expression evaluation is absolutely crucial, especially with a command line debugger (where you don't have pretty type visualizers), so it needs to be there in one form or another. I'm also currently looking into adding ICSharpCode.Decompiler as a dependency, which would undoubtedly add to the friction...

Is System.Windows.Forms.SendKeys implemented and working on Ubuntu Linux ?
I try to control JD-GUI with it, but the keys don't arrive, neither do they

They do arrive in Notepad on Windows using the same program, and they work
with JD-GUI on Windows, using the same program.
Or does it need any library installed, such as XTest/XFakeEvent ?
And BTW, Microsoft.VisualBasic.Interaction.AppActivate(Window Title) throws
not implemented...
You can use the functions:
static Window FindWindow(Window top, char *name)
static void GetFocusedWindow(void)
From xvkbd - in file xvkbd.c
Basically, all you need to do is save the mouse position, find the target
window position rectangle, and press the left mousebutton somewhere on it
with mousedown mouseup via xsendevent, then restore the mouse position.
I can supply left + right mousedown + mouseup,
I have appended cMouse.cs and the dependencies: XorgAPI + XorgStructs.
And when I loop through all processes, as shown below, I don't get a
WindowTitle anywhere...
(using mono 2.10.1 on Ubuntu)
public void GetProcesses()
{
System.Diagnostics.Process[] processlist =
System.Diagnostics.Process.GetProcesses();
string str = ;
foreach(System.Diagnostics.Process theprocess in processlist)
{
Console.WriteLine(Process: {0} ID: {1} WindowTitle: {2},
theprocess.ProcessName, theprocess.Id, theprocess.MainWindowTitle);

If you're willing to fake it, you can define functions as lambdas. It'll be ~=
to defining them in a real sense.
Try something like this:
ActionT printMe = t = Console.WriteLine (t);
or in the more complex case (retrieving some content from a webserver that
always returns GZip [yes, I did run into this while exploring some services via
the REPL]):
Funcstring, string doRequestWithPayload = payload = {
var wc = new WebClient ();
var data = wc.UploadData (http://url:port/service;, POST,
Encoding.UTF8.GetBytes (payload));
return new StreamReader (new GZipStream (new MemoryStream
(data), CompressionMode.Decompress)).ReadToEnd ();
}
It works perfectly well in the interpreter. It's not quite a real function
definition, but it's close enough for most purposes. Classes on the other hand
are a no-go.

Re: [Mono-dev] Mono Winforms on Mac (Carbon) fixes - all my source code changes attached
Hi Ralph, This sounds really cool, but my bet is that the WinForms maintainer is going to want to see it as smaller patch chunks, and preferably without whitespace/formatting changes (which it sounds like you have if you used Visual Studio's Format Document feature). You may want to also fork Mono on Github and apply these patches to your fork (make the patch applications atomic, commit often, and document the commits appropriately), then send a pull request. In my experience, pull requests make it easier for the team to review what's changed and decide whether it's good to apply. Of course, my opinions are not those of the WinForms maintainer, who may be happy to take your code as is—definitely wait for them before doing anything drastic.

Novell doesn't support Ubuntu, likely due to cost reasons--they'd pretty
much need to hire at least one more, maybe two more people to do
Debian-style packaging for Debian and Ubuntu. RPM-based distros like Red
Hat, etc. are easy, because they can modify SuSE .spec files as necessary.
This is not to say that updates to Mono can't be installed on Ubuntu. The
community packagers for Debbuntu do a good job of getting Mono releases out
shortly after the official release drops. You can find fairly up-to-date
releases for Ubuntu at http://badgerports.com, and Debian has up-to-date
releases in the experimental distribution. The reason that the official
Ubuntu repositories don't update faster is that Mono is a core framework,
and as such, requires extensive testing before it can be upgraded--due to
Ubuntu's policies, it's not likely that you'll ever see an updated Mono come
in through {distribution}-backports or any of the other update repos,
barring major security fixes, etc.
another question, why the forum keeps refreshing all the time, also during
posting? its annoying.

Both StringComparison.Ordinal and StringComparison.OrdinalIgnoreCase (as well as StringComparer) can be very useful to improve performance when culture-dependent behaviour is not needed or desirable. Culture-dependent string comparisons are a very complex topic. There's also an invariant culture for doing things in a culture-independent way. -- Michael Hutchinson http://mjhutchinson.com ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

[Mono-dev] Question about JIT performance
I've been doing some playing around and have written some code for
mathematical operations. Among those operations is something called a
box approximation for the integral of a function
( http://en.wikipedia.org/wiki/Rectangle_Rule ).
At the behest of mhutch in #mono, I tried a few things to improve the
speed of the method. The original speed was approximately 385 ms for
10,000,000 iterations of the midpoint box approximation over the
function x^3. This included 4 multiplies, 3 adds, and 1 function call
for each run of the loop, plus a one-time cost of a divide.
The things attempted to improve speed were: inlining the function, and
removing a switch() that determined if the approximation was to be
midpoint, left, or right.
Here are the results from those tests:
Iteration 1
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, no inline, w/ branch: 469
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, inlined, w/ branch: 132
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, no inline, no branch: 235
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, inlined, no branch: 250
(Much of the same here)
Iteration 10
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, no inline, w/ branch: 456
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, inlined, w/ branch: 130
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, no inline, no branch: 228
Integral of x^3 over [0, 5]: 156.25006254
Box approximation, inlined, no branch: 245
The thing that immediately struck me as odd was: how is the inlined
BoxApproximation that HAS a switch() call to check whether it's doing
left, right or midpoint faster than everything else. It's not just a
little faster, it's a lot faster. The machine running all of these tests
is running Mono trunk as of a few days ago, x86 processor with a 2.0 GHz
clock speed and 512 MB of RAM (it's a VMware server virtual machine).
Running the same thing on Mono 1.9.1 outside of VMware yields similar
results.
My question is--why is that method the fastest? Attached are compileable
versions of the Main() method and the class that holds the function
definitions.
