Apply replace without opening buffers

[shlomocarmeter]

Hi, This is a great plugin, very nice work.

I'm using neovim (v0.6.0-dev+131-g2c60f7c99) with lua file config, I tried using example from README:

" Save silently and wipeout buffers if they didn't exist. let g:esearch.write_cb = {buf, bang -> buf.write(bang) && (!buf.existed && buf.bwipeout())}

first tried:

vim.cmd([[
  let g:esearch = {}
  let g:esearch.regex   = 1
  let g:esearch.textobj = 0
  let g:esearch.case    = 'smart'
  let g:esearch.default_mappings = 0
  let g:esearch.write_cb = {buf, bang -> buf.write(bang) && (!buf.existed && buf.bwipeout())}

But this gets an error after write confirm:

Error detected while processing function 217_write_cmd[20]..esearch#writer#do[1]..376[33]..1[1]..282[1]..190_bufdo[6].. 284: line 1: E16: Invalid range: 5 buffer!

Then tried config in lua like so:

local function esearch_write_cb(buf)
  -- Not sure what to write here...
  -- vim.cmd('{buf, bang -> buf.write(bang) && (!buf.existed && buf.bwipeout())}')
end

vim.g.esearch = {
  regex = 1
  textobj = 0
  case = 'smart'
  textobj = 0,
  default_mappings = 0,
  write_cb = esearch_write_cb
}

Still no go.

Can you provide an example on how to do this in lua? (Maybe update the README?)

Thanks

Your solution:

vim.g.esearch = {
  regex = 1
  textobj = 0
  case = 'smart'
  textobj = 0,
  default_mappings = 0,
}
vim.cmd('let g:esearch.write_cb = {buf, bang -> buf.write(bang) && (!buf.existed && buf.bwipeout())}')

TLDR buf is a buffer handle to work with them using OOP API and not to deal with commands that are much harder to use. bang is true when :write! is used. With :write it's set to be false. The problem is that neovim still cannot dump viml objects properly to work with them inside lua. E.g.

vim.g.esearch = {write_cb = function(buf, bang) print(vim.inspect(buf)) end}

outputs

{
  bufnr = 3,
  bwipeout = vim.NIL,
  write = vim.NIL,
  -- ...
}

you can see that all the methods are NIL at the moment. The first snippet with your solution is completely legit, but probably in later neovim versions viml and lua will work seamlessly and your code will look like:

vim.g.esearch = {
  -- ...
  write_cb = function(buf, bang) return buf:write(bang) and (not buf.existed and buf:wipeout()) end,
}
