Errors while opening neomuttrc, and trying to compose an email from neomutt inside neovim's terminal

[poetaman]

Hi, I get following error while trying to open file ~/.config/neomutt/neomuttrc

Error detected while processing /Users/reportaman/.vim/plugged/neomutt.vim/syntax/neomuttrc.vim:

Also I do not get any syntax coloring while opening files with name <filename>.neomuttrc, though file .neomuttrc (without prefix <filename>) is colored. What extensions does this color theme apply to?

Also while trying to compose email from an instance neomutt running inside terminal inside neovim, I get the following error:

Argh! Sorry about that.
Fixed.
Thanks

@flatcap Wow, that's fast! :) Btw, I have updated the bug with another problem, don't know if its related... Will test in some time.

Also I do not get any syntax coloring while opening files with name <filename>.neomuttrc

The syntax is enabled by a condition in ftdetect/neomuttrc.vim.
It lists some file names that are likely to be neomutt config:

neomutt.vim/ftdetect/neomuttrc.vim

Line 1 in 15b0605

au BufNewFile,BufRead [Nn]eomuttrc,.neomuttrc,.neomutt/*muttrc,.config/neomutt/*muttrc setfiletype neomuttrc

You can always force the issue by adding a vim 'modeline' to the beginning or end of your config file:

# vim: syn=neomuttrc

Wow, that's fast!

Luck. You just caught me before bed :-)

Hmm... I don't understand this one -- I don't think it's NeoMutt-related.
I see the same file, rplugin.vim, in my NeoVim install and it contains a stdpath call.
According to :help stdpath it's a built-in function.

@flatcap Thanks a lot! Now I see some lines with white on red background, which I guess is for errors?

Similarly:

for line:

set index_format="     %zs %zc %zt | %-28.28L  %?X?& ? %.46s %?M10?(%1M)&? %> %{!%a %d %h %H:%M}      "

Also, I figured out the reason why I got: E117: Unknown function: stdpath. That's because my default editor is vim. And given I had neomutt instance running inside neovim, it tried to open vim inside neovim. I always get that error when I try to open a vim instance inside neovim. So I changed my .vimrc to make sure that I open neomutt with editor nvim inside nvim, and I no longer get that problem.

[flatcap]

The first block seem to be a limitation of our syntax highlighting (it's fiendishly complicated :-)
Quoting the pattern works around that:

color index color142 color234 "~N"

Changing the format of the conditionals, to use the format %<VAR?TRUE&FALSE> works:

set index_format="     %zs %zc %zt | %-28.28L  %<X?& > %.46s %<M10?(%1M)&> %> %{!%a %d %h %H:%M}      "
