Error detected while processing BufRead Auto commands for "*.py"

Question

I have a problem with my vim config...

This error occurs when opening python (.py) files:

Error detected while processing BufRead Auto commands for "*.py": E20: Mark not set 

When opening for example html (.html) or ruby (.rb) files, the error does not occur.

Here is my vim config. The plugins are all installed.

I did change the line with "BufNewFile" into different ways (1 set command, multiple set commands, with pipes, without pipes, with backslashes, without backslashes, etc.) but nothing helped.

Does anyone know what exactly the problem is?

Answer 1

It's hard to notice (I had to look twice), but the problem is the spaces between the patterns in the :autocmd definition:

The syntax is

:au[tocmd] [group] {event} {pat} [nested] {cmd} 

:help {pat} shows that there must not be whitespace between individual patterns.

Example

:au BufNewFile,BufRead *.py, *.php, *.rb, *.html, *.js, *.ts, *.md echomsg 'test'  :au BufRead *.py --- Auto-Commands --- filetypedetect  BufRead     *.py      setf python BufRead     *.py      *.php, *.rb, *.html, *.js, *.ts, *.md echomsg 'test' 

As you can see, Vim only recognizes the first pattern, and takes all following as (Ex) commands!

The :* command executes the contents of a register (probably rubbish), and that causes the E20 error you've seen (probably because there's the ' character in the register).

Fix

Drop the whitespace. As I've already commented, you can also skip repeating the :set commands for each option.

:au BufNewFile,BufRead *.py,*.php,*.rb,*.html,*.js,*.ts,*.md ...
