Is there a way to detect all the autocommand that have been triggered?

Question

I have a file for which the filetype is not correctly set.

The filetype is set by an autocmd but I would like to identify which one.

How can I know which autocmd have been triggered when I load my buffer and where these autocmd have been defined?

Or alternatively can I see the list of all autocmd that are currently defined:

• Their orders (priority)
• Their definition (script, line number)

Answer 1

I used:

:verbose autocmd

Or with the scriptease plugin:

:Verbose autocmd

I can then search the result for my file pattern (e.g. *.cfg) or the filetype it has been assigned too (e.g. cfg)

I can then filter the output with the following two commands:

:g!/\v(^\s+\*\.cfg\_.{-}Last set.*$|^\S.*$)/d
:g/^\S.*\n^\S/d

To get only the lines that are relevant for the *.cfg file pattern.
