Feature request: something similar to Vim modeline

[dievilz]

Before you raise your pitchforks and torches, hear me out for a second...

I'm just talking of a modeline to set the filetype syntax for ambiguous file extensions.

For example: Apache vs Nginx .conf files

I'm aware that Vim modelines were/are a source of security issues, that's why I'm not suggesting to add the rest of Micro options to the modeline, just the filetype one.

Something like:
# micro: filetype=nginx :
and
# micro: filetype=apacheconf :

That way, even if I have a Vim modeline at the top of a file, Micro will read its own modeline and will use the correct syntax.

What you guys think?

P.S.
Maybe we can use existing Vim modelines maybe? /s

I think mixing editor configuration with source code / configuration is a bad idea so I wouldn't want this feature built in to the editor. But you can rather easily implement it as a plugin.

Add this to your ~/.config/micro/init.lua:

function onBufferOpen(buf)
    local firstLine = buf:Line(0)
    local _, _, filetype = string.find(firstLine, "# micro: filetype=([%w%p]*)")
    if filetype ~= nil then
        buf:SetOption("filetype", filetype)
    end
end

On second thought you could also use the filetype detection in your syntax files if you only want it for a few specific filetypes.

leaving it as a plugin seems a much better solution. editor configuration in the same file is not a good idea because everyone has different setups

Thank you guys for answering!
Now I see that this idea is better as a plugin rather than builtin.

Also, I tried the snippet and it worked like a charm!
I'll try to make an appropiate plugin for this so if someone wants it, they can get it too.

When I finish the plugin, I'll post it here. For now, I'll close the discussion as resolved.
