Steps to reproduce

sample.sh:

#!/bin/bash

wurst=`command -v wurst`
echo "${wurst}"

nvim --clean -u minimal_init.lua sample.sh

Expected behavior

I would expect that when pressing = that my buffer gets formatted by shfmt. However nothing happens. This works fine with diagnostics-language-server.

I need to run: lua vim.lsp.buf.formatting_sync() to get the formatting done ...

Actual behavior

Pressing = should format the complete buffer.

This isn't my area of expertise and is not related to null-ls, but to my knowledge, = uses equalprg (see :h 'equalprg'), and I'm not sure if it can be hooked into LSP formatting.

You can use LSP formatting for gq formatting, which uses formatprg (see :h vim.lsp.formatexpr()). Other than that, your best bet is to just map the key yourself.
