          Do or can we have some info in the modeline (is it called modeline in lem ?) like so to show the encoding:

Emacs: With details:

Notepad++:

The line break format should be a useful information to display, too?

Next step could be to be able to actually change the encoding, line break format?

I can give a few hints.

Yes it is called modeline too.

There is the file src/modeline.lisp, defining:

• the list of everything to display: *modeline-status-list* it can be any element that is print-able, or a function
• some attributes to style the elements
• a function to add a custom element to it: modeline-add-status-list.

This worked:

LEM> (modeline-add-status-list "-lol-")

Then I wondered how to find the encoding.

LEM> (apropos "encoding")

gave a lot of results, searching the ones with "lem" I got: buffer-encoding, and it seems to work:

LEM> (lem-base::buffer-encoding (find-file-buffer "lem.asd")) ;; if lem.asd is open
;; => <#LEM-ENCODINGS/UTF-8::UTF-8 {xyz}>

I press Enter on it and I see in the inspector that it has two slots: BOM and END-OF-LINE (value: :LF).

See src/base/unicode.lisp with the encoding base class, and lib/encodings/utf-8.lisp with (defclass utf-8 (encoding) …).

Ready for a PR? :D
