Add ability to target header-line #133

Closed gagbo closed 1 year ago

gagbo commented 1 year ago

Hello,

Here is a small patch that adds a custom variable allowing to ask telephone-line to render in the header-line instead of the mode-line, in the spirit of nano-emacs I'm trying to see how it goes with a header-line instead of a mode-line.

(If you want to test:

(setq telephone-line-target 'header-line)
(setq-default mode-line-format nil)

)

This makes the tab-bar invisible in my setup, I'll need to figure this out first

dbordak commented 1 year ago

Let me know when you figure that out, I like the idea.

I think the tab-bar was only invisible because of an Emacs bug, even with telephone-line in the mode-line, when I have (internal-border-width . 20) in my default-frame-alist the tab-bar becomes invisible (or rather, Emacs redraws the internal border over the tab-bar). I'll need to make a proper repro case for the mailing list, but it's not related to the patch.

The other thing that I wanted to check out was "what happens if a package also wants to put stuff in the header-line ?". I tested with lsp-mode breadcrumbs feature and telephone-line gets concatenated after the breadcrumb. So it's a little weird, but multiple packages can live together on the header-line. I'll redo a review of the patch here and undraft this later this week

It should be fine actually.

For the record, it looks like that when you also have to live with other packages that force header-line usage https://i.imgur.com/8Rh7qeU.png

So, while this PR is nice to help make telephone-line a good citizen, some extra hackery might be necessary to achieve a proper swap of lines as I envisioned
