Printing out of micro

[dase78]

I would like to be able to print the actual file/saved buffer right out of Micro through the following shell-command:

lp -o sides=two-sided-long-edge -o cpi=14 -o lpi=7 -o orientation-requested=3

I just don't get it to work, even with the example of init.lua in the micro-tutorial.

It works via the shellmode in Micro but I would always have to insert the whole command + the whole /path/to/file.

But I would like to press just i.e. ctr+p and then the actual file gets printed.

Anyone to help me out?

I think it would be a function like this:

local micro = import('micro')
local config = import('micro/config')
local shell = import('micro/shell')

function init()
  config.MakeCommand('printraw', function(bp)
    -- bp.Buf.AbsPath
    local cmd = 'lp -o sides=two-sided-long-edge -o cpi=14 -o lpi=7 -o orientation-requested=3'
    local _, err = shell.RunCommand(cmd)
    if err ~= nil then
      micro.InfoBar():Error(err)
    end
  end, config.NoComplete)

  config.TryBindKey('Ctrl-p', 'command:printraw', true) -- overwrite
end

Thx taconi for the input! I tried it in two ways:

This function in an ~/.config/micro/init.lua and as a second try in ~/.config/micro/plug/printraw/printraw.lua.

The keybinding was automatically recognized in the bindings.json, but when trying to print via shortcut it exited with Status 1.

Perhaps using the RunInteractiveShell function instead of RunCommand would be ideal.

• RunInteractiveShell(input string, wait bool, getOutput bool) (string, error):
  temporarily closes micro and runs the given command in the terminal.
  If wait is true, micro will wait for the user to press enter before
  returning to text editing. If getOutput is true, micro redirect
  stdout from the command to the returned string.

Tried it out now, this quits micro immediately.

But as my workflow changed a little bit, it's not longer that important for me.

I was just surprised, that there is not already a Printer-Plugin or something like that.

Thank you anyways.

What do you mean a Printer-Plugin?
There is preview plugin, which creates a buffer and writes the result of the pandoc cli into that buffer.

I don't know if that's what you wanted.

[dase78]

With Printer-Plugin I meant something like your function. But working.

I don't know, if the mistake is at my side - did you try your function?

I don't know exactly what the lp command does, but if you want to execute a command in the terminal and see the result printed either in the terminal or inside the micro editor, I think you would do something like this in your init.lua:

-- ~/.config/micro/init.lua
local micro = import('micro')
local buffer = import('micro/buffer')
local shell = import('micro/shell')

function cat_term(bp)
    local cmd = 'cat ' .. bp.Buf.AbsPath
    shell.RunInteractiveShell(cmd, true, false)
end

function cat_buf(bp)
  local cmd = 'cat ' .. bp.Buf.AbsPath
  local output, err = shell.RunCommand(cmd)
  if err ~= nil then
    micro.InfoBar():Error(err)
    return
  end

  local path = ''
  bp:VSplitIndex(buffer.NewBuffer(output, path), false)  -- right=false
end

function init()
  config.MakeCommand('cat_term', cat_term, config.NoComplete)
  config.MakeCommand('cat_buf', cat_buf, config.NoComplete)
end

The cat_term command will execute the command and the result will be shown in the terminal, but you return to the computer with Enter.
The cat_buf command will execute the command and its result will be returned to the output variable, this value will be used to be the content of a new buffer that will be opened.

I don't know if that would solve it.

Thank you taconi, sorry for my late anwer.

The thing is, at the moment I don't find the time, to follow my "printingwish" for micro, so I will let it go and close it as outdated.
