Hello,

For my new project, I am using FPC Lazarus and I think it is very
good.
Now I am wondering, I am using this line to open an HTML file:

Shellexecute(handle, 'open', PChar(basedir +
'index.html'),'','',sw_show);

Where 'basedir' is a variable containing the application folder.
If I would do the same thing on a Mac, would that work as well ?

Greetings,
Bram

ShellExecute is a Windows API function so you can't use it on OS X.
Try this instead:

{$IFDEF DARWIN}
  Shell('Open "' + basedir + 'index.html"');
{$ENDIF}

I included double quotes in case your basedir contains any spaces.

You can also open another application using the command line Open
command. For example, to open your index.html with the OS X Help
Viewer instead of with Safari (or whatever the system's default
browser is):

  Shell('Open -a "Help Viewer" "' + basedir + 'index.html"');


Thanks.

Hey .. when I try to compile that, it doesn't recognize Shell as a
command ?
Is it included in the Mac version only ?

Shell is in the Unix unit, which needs to be included in your uses.

Please download the FPC rtl.pdf.

Thanks.

So if somebody has Lazarus installed on a Mac, does him/her has this
Unix unit ?

The Unix unit is only available on OS X and Linux, hence the need for
conditional compiling.

Download this toolkit and look at the Shell commands for OS X and
Linux in file HelpUtil.pas:

Question if I may
how do you do the same thing on Linux (e.g to open Firefox) (it says
there is no Open command)
thanks!

See HelpUtil.pas in above link.

Also, don't specify Safari in your Shell since user might have a
different browser set as default. Just specify the URL. You can see
how this works. Enter the following at a Terminal command line:

open "http://www.freepascal.org"

Thanks.
