I cannot find any way to convince SynEdit to indent the next line with a tab when I press enter on an indented line, it will always use spaces, even if eoTabsToSpaces is false and eoTabIndent is true and the previous line is intended with a Tab. Pressing Tab to indent works as expected but not the AutoIndent. I need to edit Makefile templates, they may not be indented with spaces or it will be a syntax error. The only way I have found is to disable AutoIndent completely or do a string replace after editing.

Assuming you talk about the real auto indent. Not the new codetool smart indent (that can add extra indent, after a begin)

You can select 1 of the 3
"spaces"
"space/tab" as previous line
"pos only"

press F1 the wiki describes them.

in short, tabs yes, IF the current line is also indented by tabs. Then the tabs of the current lines are copied

What combination of Options and Options2 do I need for that or how is the property called? I can't find it.

Oh in your own app, not in the IDE.

its in the beautifier

   TSynBeautifier = class(TSynCustomBeautifier)
   published
     property IndentType: TSynBeautifierIndentType read FIndentType
write FIndentType;

Make sure you have the correct beautifier, the default is one instance (not sure which class) for all edits.

There is a callback for indent too. so you can customize

Ok, assigned it a newly created beautifier, set its properties appropriately and now it works as expected.

Thank you.
