These macros work more or less like add-to-list, except they will always
leave ELEMENT as the first/last element in the list, while add-to-list
does not modify the list if ELEMENT is already present anywhere in the
list.
This is mostly a helper function for when I've messed around with active
modes in a file buffer a whole bunch, and I just want to revert all
things to the default state of when the file is opened.
Both undo-fu and undo-fu-session are hosted on codeberg, which seems to
be down right now. Hence instead let's pull in these packages from the
mirrors on the emacsmirrors GitGub org.
Use fussy instead of orderless for filtering and scoring/ordering
completion candidates. This seems to overall order results in a much
better way than just orderless.
Technically orderless is still used to filter the candidate list, but
fzf-native is used to score/order the results.
I opted for accepting copilot completions using C-<tab> /
<backtab> (shift+tab) instead of regular tab, as it was often getting in
the way of yasnippet and lsp completion suggestions. This allows a more
explicit acceptance of Copilot suggestions.
Also replace undohist with undo-fu-session.
Overall this seems to yield a more reliable undo history, as undo-fu and
vundo supposedly operate with vanilla emacs undo history state, while
undo-tree supposedly does some custom tweaks to the undo state.
Move away from the whitespace-cleanup-mode package, and instead simply
define our own whitespace-cleanup-on-save-mode minor-mode that uses a
before-save-hook.
This applies especially in lsp-mode. Yasnippet snippets now show as
completion candidates if the word at point exactly matches a snippet
keyword, otherwise it'll fallback to normal lsp backed completion.
And it also supports completing file/directory names now too while
lsp-mode is active.
All this is done by modifying completion-at-point-functions after
lsp-mode has done it's trickery with it. Along with a dirty hack to
company-yasnippet to make it only activate on exact matches. Without
this hack, lsp backed completion rarely activates as snippets would have
higher priority if there's any partial matches.
Visually ctrlf is very nice, but it seems one of it's features is to
stay active in the mini-buffer until explicitly cancelled. This can
easily lead to annoyance if you mess up a C-x C-s keybind and then move
on to other buffers and such, as ctrlf will still be active.
Regular isearch however will dismiss itself as soon as you do anything
other than typing in a search query. Hence causing a lot less annoyance
for me.
With vertico, orderless and marginalia, I feel the regular projectile
find-file and switch-project commands offer just as good if not better
completion than helm-projectile commands do. Hence the switch.
Override default straight recipe for vertico to expose extensions as
packages.
Also create hacky vertico-directory-mode to easily toggle
vertico-directory features on and off.
vertico-directory-mode is then used by a projectile advice to
temporarily disable vertico-directory features while completing results
from projectile. This is required to avoid breaking the
projectile-switch-project and related commands, as the project list is
not a set of files, but vertico-directory-enter thinks it is.
Trackpad momentum can often lead to emacs trying to resize font size by
thousands of points. Hence let's disable it, as font size changes are
easy enough via C-x C-- and C-x C-=.
I finally resolved the lsp-mode bug I had whenever I tried vertico in
the past. It was due to me setting resize-mini-windows instead of
vertico-resize.
This serves as a alternative to the code-review package. I'm adding it
mostly for testing purposes so I can compare the two and see the
pros/cons with each.
Relying on file notifications to detect changes on disk and auto-revert
buffers seems unreliable on macOS, so let's disable the use of file
notifications, and let auto-revert-mode use polling instead.
When lsp-mode is enabled, use consult-lsp-file-symbols instead of
consult-imenu, as it yields a more structured list and nicer formatted
symbol results. The result list is identical as lsp-mode updates imenu
with all file symbols, but via imenu they're just not rendered as
nicely.
