TSynEdit: linefeeds and Linebreaks
« on: September 14, 2024, 04:44:06 pm »
I have a string:
Code: Pascal  [Select][+][-]
  1.  metaData:='{'+  #13#10+ ' *******'+ #13#10+ '* Project: <Project Name>'+ #13#10;  

Which I plug into
Code: Pascal  [Select][+][-]
  1. SynEdit1.Lines.Add(metaData);
It does not split the string at  my line endings. I have tried 'LineEndings' and #13#10 with no success. How do I fix this please?

EDIT: Screenshot attached

Found what I was doing wrong. This works:

Code: Pascal  [Select][+][-]
  1. SynEdit1.Lines.Text:=metaData;

Well, yes: That.

But, if you want to add (or remove/change) to/from existing text, then you should use SynEdit.TextBetweenPoints or SynEdit.SetTextBetweenPoints. That will work with undo/redo and adjusting caret and existing selection. (And it should deal with linebreaks too)

Hi Martin, thank you I am just starting with SynEdit so have no clue am working blind and flying by night. If you have a moment please take a look at the attached screenshot and tell me if I am going down the right  path? Or I need to stop and re-think this?

You do want to start here https://wiki.freepascal.org/SynEdit
Otherwise the image is not much related on how to access SynEdit.

But as for ideas for the "class designer" (I guess you want to talk about that?):

The amount of options that you will actually need is going to grow.
So you may want
- a radiogroup: Field, Method, Property   (event is just a property)
- and then reuse fields like name
- and hide/show options like virtual or default as needed.


Just some examples:
Code: Pascal  [Select][+][-]
  1. property Foo: Integer read FFoo write FFoo; // field
  2. property Foo: Integer read GetFoo write SetFoo; // method
  3. property Foo: Integer read FFoo write SetFoo; // mixed
  4. property Foo[Bar: Boolean]: Integer read GeFoo write SetFoo; // indexed
  5. property Foo[Bar: Boolean]: Integer read GeFoo write SetFoo; default; // indexed default
  6. property Foo: Integer read FFoo write SetFoo default 5; // default val
  7. property Foo: Integer read FFoo write SetFoo stored GetStored;
  8. property Foo: Integer index 5 read GetFoo write SetFoo stored GetStored;  // indexed getter/setter
  9.  
  10. procedure Bar; inline;
  11. procedure Bar; reintroduce; virtual; abstract; overload;  stdcall;
  12. ...
  13.

Thank you for the link..

Yes please.

Code: [Select]
property Foo: Integer index 5 read GetFoo write SetFoo stored GetStored;  // indexed getter/setter
<snip>
procedure Bar; reintroduce; virtual; abstract; overload;  stdcall;
...

Thank you very much. This helps me a lot.

@Martin_fr, In the attached screenshot in the IDE source editor the compiler directive displays as red text: {$mode objfpc}{$H+}
In the running app window using SynHighlighterPas it renders as black: {$mode objfpc}{$H+}

If I would like to change this to red how do I go about doing so please?

EDIT: I did go through synhighlighterpas.pp still trying to wrap my head around it.

property DirectiveAttri in the Object inspector.

The synedit page is linked should have a link to a syn highlighter tutorial, which explains how the highlighter works.
