How can I add rules for {} and []

[ahnafalnafis]

Hi, there! Recently, I've discovered that putting \ (backslash) after { (starting curly brace) is not required in Vim9. Same goes for [ (starting square bracket). So, I decided to add a lexima rule for this. But seems like I'm unable to do that.

Current behaviour:

var blah = {
  \ |
  \ }

Expected behaviour:

var blah = {
  |
}

NOTE: Here, | is meant to be the cursor.

Here's my work:

lexima#add_rule({
  char: '<CR>',
  at: '{%#}',
  input_after: '<CR>',
  filetype: 'vim'
})

But, it turns out that I couldn't make it work. So, I'm seeking for the help from you. Thanks in advance!

From vim help:

When some of rules are conflicted, what rule to be applied is decided as the following priority order.

1. has "filetype"
2. has "syntax" (only on Insert mode)
3. "priority" value is higher
4. the length of "at" is longer

However, lexima does not have the rule about backslash for vim by default. Please provide your configuration.

Not sure what configuration are you talking about. Here's my configuration for lexima.vim

vim9script noclear

# To prevent having conflict with coc.nvim
g:lexima_no_default_rules = true
lexima#set_default_rules()
lexima#insmode#map_hook('before', '<CR>', '')

If you need further details, here's my vimrc. This is all I got for you. https://github.com/ahnafalnafis/dotfiles/blob/master/home/.vim/vimrc

Finally, I figured out what was wrong. It was coc#on_enter() which was doing this. Now, I turned it off. Pardon me guys for the mess 😓. Thank you @4513ECHO
