With khzaw/vim-conceal conceal works in python.

any ideas?

  • Check if you can find +conceal or something like that in $ vim --version command from the shell or :version from the vim instance. This will tell if you have compiled vim with conceal feature or not. On second thought, just post the whole output of :version here. – klaus Mar 26 '19 at 12:18
  • What do you mean with it doesn't conceal text? What have you tried to conceal Tex? Have you read :h ft-syn-tex (or more specifically :h g:tex_conceal?) – Christian Brabandt Mar 26 '19 at 12:27
  • When I see this not so minimal vimrc, you should be made aware of the question How do I debug my vimrc file?. This explains how a problem can be isolated by bisecting the vimrc. This should be one of the first debugging steps before raising a question. – Hotschke Mar 26 '19 at 13:14
  • I cannot reproduce the example given by the OP. Also please note, that you did not provide a minimal working example that reproduces your problem. Just throwing it at the vim issue tracker and make others figure your problem out is not really helpful. If you really think this is a vim bug, please come up with a minimal example. – Christian Brabandt Mar 26 '19 at 14:34

You should remove augroup remember_folds commands

    Hi, thanks for contributing. You should however explain, why this is needed. – Christian Brabandt Mar 26 '19 at 12:50
  • I had the same problem once and I tried removing random things from vimrc. I have no idea why it works tho – w0nsh Mar 26 '19 at 14:25

The reason removing augroup remember_folds helped was given here: https://github.com/vim/vim/issues/4175. Basically neither mkview nor loadview remember filetype nor syntax. Quick fix to that problem is modyfing those commands. The augroup remember_folds should look like this:

augroup remember_folds
    autocmd BufWinLeave ?* mkview | filetype detect
    autocmd BufWinEnter ?* silent loadview | filetype detect
augroup END
