Hello Joao Paulo,

I am very happy that you continue to develop CAI!!

Networking and Web Programming / Re: Who is Indy mattias?
« Last post by jollytall on Today at 11:01:45 am »
The error messages are as said above. I made a screenshot of the first errors:

What I also tried is another project that compiles just OK (and does not use any networking, indy or other). Then I add in the Project Inspector the freshly downloaded indylaz to the Required Packages (no unit mentioned explicitly) and I get the 73 error pairs like the ones on the screenshot and obviously a 74th error "Error while linking". If I remove it as a required package then my project (the one without networking) compiles again.
In my networking project, I cannot remove the required package because then the units are not found.

Android / Re: dwindows for Android
« Last post by PierceNg on Today at 10:54:44 am »
Coming back to this after a (long) break, I've now built a demo/exercise app using a webview widget for the user interface, with bidirectional Javascript-Pascal in-process RPC.

The main body of the code loads in-app static content, then binds the names 'HostSayHello' and 'HostExit' for callback to Pascal code from Javascript. Said Pascal code in turns invokes Javascript to manipulate the DOM.

Code: Pascal  [Select][+][-]
  1.   webwidget := dw_html_new(1001); // 1001 is an identifier
  2.   if webwidget <> nil then
  3.     begin
  4.       dw_box_pack_start(mainwindow, webwidget, 0, 0, DW_TRUE, DW_TRUE, 0);
  5.       dw_html_url(webwidget, 'file:///android_asset/index.html');
  6.       dw_html_javascript_add(webwidget, 'HostSayHello');
  7.       dw_html_javascript_add(webwidget, 'HostExit');
  8.       dw_signal_connect(webwidget, DW_SIGNAL_HTML_MESSAGE, @html_message_callback, nil);
  9.     end;

Screenshot of the app running in Android emulator attached.

FPC development / Re: create system unit from scratch
« Last post by Laksen on Today at 10:53:57 am »
jmp_buf is a record used to store the state of the CPU for the setjmp and longjmp procedures. This functionality is used for exception handling. They are already implemented for MIPS in rtl/mips/setjump*.inc which is included by systemh.inc

TExceptAddr is as the name hints also used for exception handling and implemented in a generic way shared by all the targets in excepth.inc included by systemh.inc
TGuid stores a GUID. The compiler needs to point to it during compilation when GUIDs are needed. Also implemented in a generic manner in objpash.inc included by systemh.inc


The key to implementing a systems unit is to get the proper defines, paths and system specific dummy functionality (usually residese in sys*/tthread/check.inc files) implemented. There's no documentation but you should see how other system units are structured

Beginners / Re: how to get class and method name from inside the method
« Last post by cdbc on Today at 10:52:22 am »
Hi
Try playing with:
Code: Pascal  [Select][+][-]
  1. lptr:= MethodAddress(Classname+’.’+{$I %CURRENTROUTINE%});
  2.  
Note: When you have this pointer, you can also use 'MethodName();' with it...
edit: I dunno if the 'ClassName'-part is necessary   %)
Regards Benny

Thanks blueicaro
That works great once I add classname +’.’

I also wonder if there is a way to get a pointer to procedure I’m in and then send the pointer to another error message procedure which would be able to extract procedure name and make error message

Databases / Re: Database standards OR Am I doing this right?

@egsuh: Generally, it should be the case that a record should have a semaphore set to inform other users that it is being edited.
But without information about the specific case, it is difficult to say anything.

I gonna implement only the minimal requered code in the system unit

pls explain what  type

1)  jmp_buf
2) TExceptAddr
3) TGuid

do and what is minimal implementation of thouse.

I found https://wiki.lazarus.freepascal.org/System_unit

but there is no detailed explanation

What is the exact error message?
Mattias Gärtner has built the release packages of Lazarus for Linux and MacOS. His home path must be left somewhere although I don't know how it can affect the compilation of your project.

Hello,  you can use {$I %CURRENTROUTINE%}, more info: https://www.freepascal.org/docs-html/prog/progsu41.html#x48-470001.2.41

Here there is a example: https://forum.lazarus.freepascal.org/index.php?topic=49837.0
