Repeat last edit n times

Did you ever wish you could repeat the last edit an arbitrary number of times without mashing the . key?

Well now you can.

" markdown : jump to next heading

function! s:JumpToNextHeading(direction, count)
    let col = col(".")

    silent execute a:direction == "up" ? '?^#' : '/^#'

    if a:count > 1
        silent execute "normal! " . repeat("n", a:direction == "up" && col != 1 ? a:count : a:count - 1)

Linting your code, the vanilla way

You may want a linter plugin to lint your code in Vim but you probably don't need it. At least try the built-in way before jumping on the plugin bandwagon.

Defining makeprg

autocmd FileType <filetype> setlocal makeprg=<external command>

This autocommand tells Vim to use <external command> when invoking :make % in a <filetype> buffer. You can add as many similar lines as needed for other languages.

Dealing with autocommands

Anatomy of a minimal autocommand

autocmd BufNewFile,BufRead *.foo set filetype=html

• BufNewFile,BufRead is the list of events that trigger this autocommand.
• *.foo is the pattern we want to match against the data returned by the event.
• set filetype=html is the command we want to execute when the pattern matches the data returned by the event.

The right way to override any highlighting if you don't want to edit the colorscheme file directly

Generalities first

Suppose you have weird taste and you absolutely want:

• your visual selection to always have a green background and black foreground,
• your active statusline to always have a white background and red foreground,
• your very own deep blue background.

Docker-based Web Application Setup (example)

This is an example of hosting standalone web front-end (web) and data API (api) applications under the same domain via Nginx (acting as a reverse proxy) and Docker, where HTTP requests starting with example.com/graphql and example.com/login/* are being redirected to http://api:3000 and everything else under the same domain is going to be passed to http://web:3000.
