[jiz4oh]

can confirm this issue occured after 79456dc, and only happened with set regexpengine=1

can simply reproduce by add set regexpengine=1 in vimrc, then start vim

Hi @hrsh7th, could you help looking this?

[riodelphino]

I faced same issue.

E5113: Error while calling lua chunk: ...e/pack/packer/start/cmp-cmdline/lua/cmp_cmdline/init.lua:38: couldn't parse regex: Vim:E369: Invalid item in \%[]
stack traceback:
        [C]: in function 'create_regex'
        ...e/pack/packer/start/cmp-cmdline/lua/cmp_cmdline/init.lua:38: in main chunk
        [C]: in function 'require'
        ...ck/packer/start/cmp-cmdline/after/plugin/cmp_cmdline.lua:1: in main chunk

As @jiz4oh said,
when I add the vimscript below (for 'Far' plugin), this happens.

set regexpengine=1        " Error occurs.

And if I remove or comment out this line, the error goes away.

" set regexpengine=1        " Error goes away.

Is this the only solution ?

Thank you.
