I made a syntax file with among others a comment region.

It should work like the "c" syntax. Starting with /* and ending with */.


if exists("dbquery_fold")
    syn region dbqueryComment start="/\*" end="\*/" contains=... extend fold
    syn region dbqueryComment start="/\*" end="\*/" contains=... extend

On the whole it works. If I scroll down, either with j or with Ctrlf the whole comment is colorized correct. On :let dbquery_fold=1 I can fold it.


I have a very long comment e.g. at the end of a file.

  1. I press G to go to end of file.
    => The comment is not Identified. The text is colored with normal syntax colors.
  2. If I scroll to the end Ctrlf and then back, no matter how
    => Not all lines are colored as comment. At first all lines are correct and then one line is colored and 6 not. Or 3 are colored and some not.

How can I tell vim to show it all as comment?

The file looks like:

Line 1  
Line 120  
Line 122  
Line 922

    :syn sync ccomment should probably fix it, otherwise :syn sync fromstart; see :help syn-sync. There's some more subtleties involved that should be in a good (full) answer though. Aug 22, 2022 at 13:21

    @MartinTournoij - syn sync fromstart and syn sync fromstart works! And it seems fast enough. I think you should set your comment as answere. Thanks!
