Search selected text and apply macro in match

These are the keymaps I used in the demo.

-- Begin a "searchable" macro
vim.keymap.set('x', 'qi', [[y<cmd>let @/=substitute(escape(@", '/'), '\n', '\\n', 'g')<cr>gvqi]])

-- Apply macro in the next instance of the search
vim.keymap.set('n', '<F8>', 'gn@i')

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/544552 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
