set g:vim_json_syntax_conceal = 0 in insert mode

[davidchambers]

Is it possible to disable concealing entirely when entering insert mode? If so, how? I played around with autocmd in my .vimrc but couldn't figure it out.

The InsertEnter and InsertLeave hooks might be helpful.

This is working for me in my vimrc:

autocmd InsertEnter *.json setlocal conceallevel=2 concealcursor=
autocmd InsertLeave *.json setlocal conceallevel=2 concealcursor=inc

You can probably do away with the conceallevel=2 parts to leave that variable as it was. Check to make sure.

I'm using the indentLine plugin which, since it uses an after/plugin file structure, would normally override any conceal config in vimrc.

This is one messy interaction that is kind of inherent to the overeager indentLineplugin (I'm guessing @davidchambers also had it installed and the problem has happened before). To try to preserve the illusion at all times of their indenting vertical-lines they go too far and disallow disabling concealing in any mode.

I think the best solution if you're using indentLine is to do

let g:indentLine_noConcealCursor=""

in your .vimrc (that is, set it to empty). This will allow you to see the concealed javascript punctuation in the current cursor line when in normal & indent mode as intended.

(An intermediate step could be let g:indentLine_noConcealCursor="nc" which would enable vim-json only when actually in indent mode.)

The code that @appleYaks gives also works (no need for the conceallevel=2 part).

@elzr thanks for researching this!

let g:indentLine_noConcealCursor=""

Thanks for your explanation, it worked with a different string for me: let g:indentLine_concealcursor=""
