* Allow customization of all floating window borders
Users may not necessarily want the same border character for top+bottom
or left+right, so allow all eight border characters to be configured in
g:ale_floating_window_border.
For backwards compatibility, the old rules are still applied if only six
elements are given.
* Reorder popup border array for compatibility
The previous linter rule about stray echo lines has been restored, and
now all problems for custom linting rules can be ignored by adding a
comment above problem lines.
* implement vim popups for preview
Details on implementation
-------------------------
- we make use of the |popupwin| api
- we split implementations (Nvim* vs. Vim* prefix) and call the right
one based on has('nvim')
- we follow a similar structure in each function, using the relevant API
- popup_list, win_execute, popup_settext in VimShow
- popup_create in VimCreate
- popup_close in VimClose
Some differences
----------------
- we DON'T have VimPrepareWindowContent because we use arguments to
popup_create for borders, padding, etc., and it also takes care of
buffer creation.
- we follow the protocol of setting and using w:preview for information,
but we only need the ID
- InsertEnter is the only autocommand required, because of
popup_create's moved argument. Any cursor movement with 'any' will
close the popup. This in turns means VimClose is only called from
InsertMode, so no mode-restoration necessary
- we don't tweak too much in the buffer because vim's popup buffers
already have most relevant settings and aren't editable without
calling popup functions.
- I enabled scrollbars, close buttons, dragging, and resizing
- vim popups get as big as they need to by default, so no worrying about
truncating/hiding/size
Note: we might want to consider changing w:preview to w:ale_preview to
avoid clashes if someone else tries to use the same variable
* floating window: document that vim supports it
* lint: fix indent/cont. lines
* Add nvim floating window hover support
* Add configuration for float to replace preview
* preview#ShowFloating: qualify local variables
* Configure floating preview usecases individually
Also:
* Extract floating preview to its own file.
* Ignore 'stay_here' option. Moving into the floating preview window
seems confusing at best.
* Re-use existing floating preview window if it's still up.
* Flush out floating preview documentation.
* Watch cursor position changes per window
Floating previews open a new window, so when that window is written to,
it moves briefly there at a different position than the original window.
This makes repeated positions detected when positions are tracked at a
s: level. Instead, we change the variable to window scoped, which only
fires a message if the cursor has changed from the last position in
*that window*.
* g:ale_floating_preview cleanup
* floating_preview: add ALEDetail tests
* Fix fecs test missing runtime call
* Add ALEHover floating preview tests
