How does mod harbour work

[Otto]

Dear Antonio,
can you please show us how mod harbour works?

Can we say?
<?php and ?>
is the equivalent for
TEMPLATE
ENDTEXT
in mod harbour and that this PHP description is valid for mod harbour, too?

Best regards,
Otto

PHP tags
When PHP parses a file, it looks for opening and closing tags, which are <?php and ?> which tell PHP to start and stop interpreting the code between them. Parsing in this manner allows PHP to be embedded in all sorts of different documents, as everything outside of a pair of opening and closing tags is ignored by the PHP parser.

PHP includes a short echo tag <?= which is a short-hand to the more verbose <?php echo.

Hello friends,

In mod harbour we have Harbour as a language by default.
In PHP/ASP I think HTML and then you switch with <scritpt>.
In mod harbour is HARBOUR first.

This is what a person switching from HTML or PHP does not understand at first.

What are the technical terms for this?

Ruth says for a coherent syntax we (HARBOUR users) should use

<script type="application/harbour"> instead of TEMPLATE.

But for us it should be
<script type="application/html">.
I'm between the lines here.
We want as much HABOUR syntax as possible and the newcomers who don't know HARBOUR as little as possible.

Best regards,
Otto

Dear Otto,

Harbour is very powerful using strings, so basically what we do is search for "<?prg" and then for "?>" and what it is in between is compiled and replaced

Harbour incredibly feature to compile in runtime lets us do incredibly things.

that simple

Dear friends,

I use

Code: Select all  Expand view

ENDTEXT
? "test1"
? "test2"
TEMPLATE
 

which works fine...

but would prefer something like this in some situations...

Code: Select all  Expand view

<?prg
? "test3"
?>

do I need to escape the "?" in this context, because the code-example doesnt seem to work.

what is working

Code: Select all  Expand view

<?prg
return "test4"
?>

but not multiline

Code: Select all  Expand view

<?prg
return "test4"
return "test5"
?>

Thank you a lot in advance and kind regards
Ruth

Dear team,


I kindly want to ask another question about "How does mod harbour work".
On some occasions I get very useful error messages - like for example

Error: LOCAL declaration follows executable statement
operation: line:593
called from: HB_COMPILEFROMBUF, line: 0
called from: ..\source\exec.prg, EXECUTE, line: 68

Source:
0066: cPRGPATH := hb_GetEnv( "PRGPATH" )
0067: cPRGPATH := STRTRAN( cPRGPATH , "/", "\" )
0068 =>cdbf_BLOG := cPRGPATH+ "\data\BLOG.DBF"
0069: lRecord := .T.
0070:

but I make a lot of other mistakes too, where I don´t "see" the error right away ... like for example trying to return a numeric value

Code: Select all  Expand view

<?prg return hWarenkorb["Variante2"]["Zimmer1"]["Subtotal"] ?>

could I set up some error messages somewhere for my common mistakes? so that the programm "tells" me "Error: STR() missing for numeric value..."


thanks again for your attention and kind regards

Dear Ruth,

Instead of doing:

Code: Select all  Expand view

<?prg
? "test3"
?>

use:

Code: Select all  Expand view

<?prg
AP_RPUTS( "test3" )
?>
