Vim only show current line / hide every other line

Question

My question is if there is a possible way to hide everything except all text except the current line?

---

Some background: I have a really big JSON file which I just did a macro on and am doing a quick eyeball to see that everything looks alright.

What I'm currently doing is searching for a specific keyword and going next.

eg: /"Name": and holding n to go to the next result. (dw n is already mapped to nZZ)

This is really useful at the moment, but it's also very distracting to see other information on the top and bottom constantly changing.

Is there a possible way to hide everything except the current line (image for reference)?

Answer 1

I think you can use 'Conceal' feature. For example,

:match Conceal /^.*$/
:set conceallevel=3

All the lines except current one will be concealed. If you do not like the 'Conceal' color,

:highlight Conceal NONE

When you finish, just do

:match

You could use "vimgrep" to get all the results in a quickfix window and jump to the results you want to.

Not exactly what you're looking for but a workaround.

Example:

vimgrep /"Name":/j | cw

Note: Switch between quickfix window and the buffer using CTRL-W CTRL-W

One way to achieve this would be to set all your highlighting groups to have the same foreground ctermfg/guifg and background ctermbg/guibg colours, and then use set cursorline and the CursorLine highlight group to change the colour of the current line.

However, an easier way to do it is to install the Limelight plugin.

You'll need to add the following configuration to your .vimrc in order to make Limelight focus on a single line:

let g:limelight_bop = '^'
let g:limelight_eop = '$'

You can then switch Limelight on and off with the commands:

:Limelight 1
:Limelight!

N.B. The 1 in the command above is an opacity/intensity parameter. If you do not include it, or use instead a value between 0 and 1, then Limelight will dim down the other lines, but not hide them completely.

This solution looks simple enough :

:syntax match Ignore /^\(.*"Name":\)\@!.*$/ containedin=ALL
