Mini.statusline customisation

[Klvxn]

Aside from unreasonably increasing the value of trunc_width , is there a way to get the short output for sections in the status line?
For instance, fileinfo returns filetype, encoding, format and file size. however what I'm only interested in seeing are just filetype and encoding. Same goes for location — line number & column

An answer to the exact question is a "No". However, most of the sections are more or less thin wrappers around built-in 'statuslin' syntax. So...

For instance, fileinfo returns filetype, encoding, format and file size. however what I'm only interested in seeing are just filetype and encoding.

Instead of section_fileinfo(), use something like this:

local fileinfo = vim.bo.filetype

if fileinfo ~= '' then
  fileinfo = string.format('%s %s[%s]', fileinfo, vim.bo.fileencoding or vim.bo.encoding, vim.bo.fileformat)
end

See section_fileinfo() code for more details.

Same goes for location — line number & column

Instead of using section_location, use '%l│%2v' string directly.

Sorry to revive an old question, but when you say "Instead of ..., use something like: ...", how does one put that in say a mini.statusline.lua or lazy.lua or init.lua? From :set statusline I get:

statusline=%{%(nvim_get_current_win()==#g:actual_curwin || &laststatus==3) ? v:lua.MiniStatusline.active() : v:lua.MiniStatusline.inactive()%}

would it be best to change what active() function does? Redefine it after loading mini.statusline?

Not quite. It requires setting custom config.content.active, then MiniStatusline.active will use it automatically. Here is a more detailed answer, which uses custom function for file name (instead of directly using MiniStatusline.section_filename()).
