syntax coloring ignored in actions triggered by events

[Edward Peschko]

All,

I'm hitting an odd bug when I define an event which involves splitting a window. I've isolated it down to the following example:

autocmd CursorMoved * :execute ":silent! split /perl/module/mymod.pm"

where mymod.pm is a valid perl module with valid perl syntax.

In any case I have syntax coloring enabled for perl modules, yet when it hits a CursorMoved event it splits the window displaying the code but NOT coloring the syntax. When I run

:hi

it shows all of the highlighting configurations so I'm pretty sure it has something to do with the event combined with the execute action. Running:

:syn on

after the CursorMoved event happens is ignored.

Anyways I'm running the latest 8.1 source - I tried it with a python module and a vimrc file and both hit the same issue.

if there is a vim bug repo let me know and I'll file an official bug.

thanks much,

Ed

(ps - one other bug - it looks like a split event triggered by CursorMoved at the very outset - right after the editor loads up - causes vim to freeze until an interrupt is given. )

You probably need the nested keyword for your autocommand

Christian -

I don't see any documentation on that keyword inside of vim. Not seeing much on the internet either.

Can you give an example and why it is needed - or am I missing something in the docs?

Thanks much,

Ed

:help autocmd-nested

You can find this by typing

:help nested

and hitting Ctrl-D to list help entries containing "nested". See
just

:help

You can also use :helpgrep to search the documentation for words or
patterns. For example,

:helpgrep :au.*nested

finds 10 matches, including an entry in the user manual in
usr_40.txt.

Regards,
Gary

thanks Gary, I found it by doing grep -r of the vim source directory. Your methods are much cleaner though...

Sorry, I wasn't in front of my desktop PC when I wrote the answer, so
couldn't point to the right vim documentation. In addition, the nested
flag has just been recently switched from using the default keyword to
using the ++nested keyword, so depending on your vim version, it's a bit
different.


Best,
Christian
