[Solved] Handling long lines in source with Lazarus IDE editor
lazarus / 9-Editor

----------------------------------------------------------------------

Hi,

as there any option in the lazarus source code editor to wrap long
lines?

Or is there any possibility to write a long source code text row in
multiplex rows?

In other languages it works with an "\" at the end of the line, e.g.

char* s = "sfgsdfg \
    asdfasdf\
    sadfsdf";

Or sometimes with an "_" at the beginning. But in freepascal it
doesn't seem to work.

Some code editors have an option to handle long lines, which is for me
the most comfortable way to code...

Thanks,

Markus

Did you try "+"? Like this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var  s:
string;begin  s := 'aaaaaaaaaaaaaaaaaaa' +      
 'bbbbbbbbbbbbbbbbbbb' +        'ccccccccccccccccccccccccc';end;

Great, that works. Thanks!!   

But with code lines other than strings (e.g. a long if statement)
there is no possibility to handle long lines...

Am I right, that there is no switch in the editor preferences to
enable some sort of line wrap directly in the editor to handle long
lines?

Best regards

you are in pascal now where the crlf is not considered end of
statement eg
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i       if (i
= QueryList.Count - 1) or         ((Trim(QueryList[i + 1]) <> '') and
 (Pos('/*', Trim(QueryList[i + 1])           ) <> 1) and       
 (Pos('--', Trim(QueryList[i + 1])) <> 1)) then          Break;  which
you can write as
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i       if
(i          =          QueryList.Count          -          1)        
or          (          (Trim(                QueryList[i + 1]        
     )           <>           '')           and           (Pos(      
        '/*',                Trim(                     QueryList[i +
1]                    )                )            <>            1  
       )           and         (Pos('--', Trim(QueryList[i + 1])) <>
1)) then Break;    with out problems except the readability one that
is.

Ah ok, thanks. Now it is clear to me .

I tried the same with a string const (nearly like the C example in the
initial post) and that didn't work like this. But with the "+"
solution it works for strings.

Thanks for your help!

Best regards

The editor can also auto continue strings or comments.

Menu / Tools / options / editor / general / tab + indent.

If enabled and you press return while inside a string, it will add   '
+ at the end of line, and ' at the start of the new line.

That's a good hint, thanks.

@edit: I tried to find this option, but in my Lazarus IDE it isn't
available? The problem is, that I am using the german version of the
IDE, so the texts differ. But there seems to bo no such option in the
Editor --> general preferences...
See attached screenshot...

Bye,
