Another problem is that it doesn't solve the main issue which is that Android does not officially support running native programs, they need to be libraries. Of course I ignored this and managed to run native programs, but that's another story. In short I don't think that I will change my development strategy for now, specially since I already bought a Android 2.1 phone and I can write Pascal apps for it at the moment and I don't plan on dropping support for it at the moment.

[fpc-pascal] FPC programs in Android without JNI
Hello, There was already a previous thread about Android apps with JNI, so I thought I should start one for discussing non-JNI apps, which means that I am really running executables as opposed to linking a .so to Java via JNI. I succeeded in running a simple FPC Pascal application in Android and showing it's WriteLn output in a message dialog: http://p-tools.svn.sourceforge.net/viewvc/p-tools/PascalNotes4Android/?pathrev=190 Basically you need to rename your app so that it looks like a .so and then upon initialization the Java app needs to copy it to a folder where it can run the application. The folder is returned by getApplicationContext().getFilesDir which points to /data/data/packagename/ and then I use chmod to make the executable runnable. I don't know how it will fare for apps running for prolonged amounts of time at the moment, some Android developers said it is possible that it won't work. The Pascal app needs to be compiled separately and placed in the lib/eabi folder. Then after that issue ant debug to build the APK installer. bye, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

As long as I remember, even first Windows CE binaries could be created for several processors architecures, while the main competitor, Palm, only to a single (Motorola). The latter was a real benefit for general user. Of all other factors which make Palm obsolete you picked up a small technical detail which the users couldn't care less about. Managed code (if I understand this concept correctly) would allow exsting multiply process architectures transparent to the developer. Imagine x86 architecture would finally overcome power-saving issues and be the winner over ARM (unlikely, but just imagine), who would not suffer? Andorid and Windows Phone, and who would have hard times? iOS and Symbian This problem is non-existant. In the worse case you have one download per architecture. And yes, sure, yeah, right that managed code solves anything. I know a couple of Android apps which have different downloads for version 1.5, 1.6, etc, because of platform differences. How is it better then one download per architecture + a good designed API with better compatibility? Even then you can have something like the Universal Binaries from Mac. Plus, Mac OS X had no trouble migrating to x86. If anything it was only better then developing for PowerPC. You can see it as an excelent example of a successful platform migration. And if they want to virtualize something they could virtualize one processor, like Rosetta virtualized PowerPC in x86 Although, on the other side, if your writing native, you will invest in something more solid. Motorola processor is gone, but the c code for example of my reader for PalmOS is open source and anyone can change it at least leaving some code from the past.

Here the compiler assumes that your source code is encoded in the
default system encoding and then it converts your string to utf-16.
Probably your system encoding is not UTF-8. so your string is
corrupted by a wrong conversion. Then length 8 seams to indicate that
the string was corrupted.
You could tell the compiler that your source code is in UTF-8, which
should allow the code above to work, but then it will break all utf-8
ansistrings. There is no real solution for this issue while FPC lacks
full Unicode support. In the mean time I recommend using your second
version of the code.
It is different with
ws:= UTF8Decode('زاهر');
Label3.Caption := inttostr(length(ws));
//= 4
This is more like the standard Lazarus way of doing things. The string
is encoded in the file as utf-8 and assigned to a ansistring. Then
UTF8Decode converts this to UTF-16. A correct conversion takes place,
because you didn't let the compiler decide for you what to convert,
but you decided yourself.

Just one suggestion: If the current TThread uses too many security facilities for your purpose, then I think that it may not be possible to make a single thread manager which fits all purposes. So you could create your own high-performance thread manager, and for most users which don't need this feature, but prefere safer threads, can keep using the current thread manager, cthreads in UNIXes. So you can still use the standard TThread object, just add your own high_performace_thread_manager unit to your uses clause instead of cthreads. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] Extended, Currency and TDateTime memory layout
Hello, I managed to read the extended by putting it in a program like this: procedure TForm1.Button1Click(Sender: TObject); var Hex: array[0..9] of Byte; Num: Extended; begin Hex[0] := $00; Hex[1] := $00; Hex[2] := $00; Hex[3] := $00; Hex[4] := $00; Hex[5] := $00; Hex[6] := $00; Hex[7] := $80; Hex[8] := $FD; Hex[9] := $3F; Num := Extended(Hex); Caption := FloatToStr(Num); end; And that just confirms it, yep, the server converts the currency to extended ... -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Interresting enough, the exact same value is returned. From my research on this subject a floating point is something like: Sign bit || exponent bits || decimal places Num = sign * (2^(exponent - offset) + decimal places) And the server only sends numbers like: 0,25; 0,5; 1; 2; 4; etc All those numbers can be fully represented using the exponent, so the double conversion maintains them exactly the same. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] Extended, Currency and TDateTime memory layout
Hello, I am interfacing with a server written in Delphi via network and it sends over data. The server sends some data types, and among the hardest ones to read are Currency and TDateTime. The server is undocumented and does some strange transformations of the data using RTTI to pass properties. I always though that Currency was a special kind of integer type, but it seams that RTTI will return tkFloat for it under Delphi. Where is the internal memory layout of Currency documented? Where is it declared in the compiler? I couldn't find it... Similarly, it seams that most often TDateTime=double. Any docs on the memory layout of TDateTime? Before sending the data over, the application seams to convert both types to Extended ... any docs on the memory layout of that? I am trying to convert the data that the server sends into a readable number, but it doesn't seam to work, so maybe the memory layout of this would help ... A snap of what kind of stuff the server does: var FloatProp: Extended; PropCnt, I: Integer; PropList: PPropList; begin ... PropCnt := GetPropList(Result,PropList); for I := 0 to PropCnt - 1 do begin case PropList[I].PropType^^.Kind of tkFloat: begin Stream.Read(FloatProp, SizeOf(FloatProp)); SetFloatProp(Result, PropList[i], FloatProp); end; Plus, the Extended type is limited to x86 or does it also exist under x86_64? As in having the same memory layout... If it doesn't exist, does anyone know a function to read/write an extended even without hardware support? thanks, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

[fpc-pascal] fpweb tutorial
Hello, Does anyone know where I can find documentation or a tutorial about fpweb? Also, is the version included in FPC 2.4.0 very old and I should really use the FPC SVN code or can I use the units that come with FPC 2.4.0? I want to make a simple page which converts hexadecimal to a string. I found some, but they were really crappy. Plain CGI should be the prefered format, as apache modules are too much for this simple task. thanks, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] fpweb tutorial
Hello, Thanks, with this blog I seam to be going somewhere and it worked ok with fpc 2.4.0 and the weblaz.lpk package. One thing still: Is there support for templates? I am doing something like this to load my page: procedure TFPWebModule1.DataModuleRequest(Sender: TObject; ARequest: TRequest; AResponse: TResponse; var Handled: Boolean); begin AResponse.ContentType := 'text/html;charset=utf-8'; AResponse.Contents.LoadFromFile(ExtractFilePath(ParamStr(0)) + 'mainpage.html'); Handled := True; end; Something like powutils templates would be extremely handy ... all that html mixed with pascal doesn't look very nice. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] Search Engine friendly CGI web apps and pages
In the standard Apache setup it will thread anything you put in the cgi-bin directory regardless of the extension as a cgi program. The path to this is set in httpd.conf here: # # ScriptAlias: This controls which directories contain server scripts. # ScriptAliases are essentially the same as Aliases, except that # documents in the target directory are treated as applications and # run by the server when requested rather than as documents sent to the # client. The same rules about trailing / apply to ScriptAlias # directives as to Alias. # ScriptAlias /cgi-bin/ C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin/ -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] A patched unit overriding the default - like Delphi supports
The solution that I use is to rename the unit slightly, like I am improving OpenSSL.pas, so I renamed it to MyOpenSSL.pas to avoid conflicts. Once the changes are merged and released I will rename my uses clauses back to OpenSSL. Can be very annoying if the problem involves lot's of units, but for simple cases works fine. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] LNet
I sent a direct main to Almindor and he answered my questions. Basically there is no direct way to detect the barrier between packages, you have to make your packet structure allow for that, but luckly mine was already prepared for this. And from my tests Get is indeed returning the amount read. I still don't know if half a packet could be received in the OnReceive event or if it only returns an integer amount of packets. That makes difference in the algorithm to separate the packets. -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] LNet
Hello, I am trying to use lNet and I have some questions. 1 Can I use TLTcp or do I need to use the visual version, TLTcpComponent? 2 Can I use only the base package or do I need to use the visual one? Basically I am not a big fan of design time packages, I prefer to add the units and create the components myself. 3 Does LNet require some kind of support for the widgetset? I am curious if TLTcp will work in Mac OS X or if it requires some support for the Carbon widgetset. And if it already works, then what is the mentioned support for widgetsets? thanks, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] LNet
Ok, thanks, now I seam to be able to get it working using TLTCPComponent, but I am unsure about how to read data. Ok, I read that it will call OnReceive when there is data ready, but I couldn't find anything about how much data is waiting to be read? I would like to get each single Packet which is sent to my program and store them in a Queue, which will later be dealt with, but using only the Get method I don't see how I can Find out how much data is available. Without this I don't know how big a buffer I should send for this function, but I guess I could just give a very big buffer, but then there are no comments in the function indicating if it returns the amount of bytes written. Also, how would I know where are the packets separated? I mean, two packets could arrive very quickly and I would be reading both together instead of first the first one and then the next one. thanks, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
