This will be a living document. + +# Fixes +## General Stutters (Caused by Garbage Collection) +Garbage collection stutters is a common problem among Emacs users, and I have a constroversial solution which has worked for me. Basically: **only garbage collect when you are idle** (even for short periods of time). Read more about it [here]((@/blog/emacs-garbage-collection.md). +```lisp +(defun my-minibuffer-setup-hook () + (setq gc-cons-threshold most-positive-fixnum)) + +(defun my-minibuffer-exit-hook () + (setq gc-cons-threshold 800000000)) + +(setq gc-cons-threshold most-positive-fixnum) + +(run-with-idle-timer 1.2 t 'garbage-collect) +``` + +## Lsp-Mode Gives Bad Completion Results +Sometimes completion results won't refresh or refilter. This one pissed me off for a while because I couldn't quite nail down whose fault it was. It turns out that it was `lsp-mode` being overzealous with caching. There is a [cape](https://github.com/minad/cape) transformer which breaks the cache and fixes the results. Here's part of my config: +```lisp +(use-package cape + :init + (defun my/lsp-capf-busted () + "Return an uncached LSP completion function." + (cape-capf-buster #'lsp-completion-at-point)) + (add-hook 'lsp-completion-mode-hook + (lambda () + (setq-local completion-at-point-functions + (list (my/lsp-capf-busted)))))) +``` + +# General Advice +## Which Lsp Client? +I use `lsp-mode`. I would love to switch to `eglot`, but I really like `lsp-ui`'s peek feature and it hasn't been ported to eglot yet. +There are several other lsp clients meant to increase speed (such as [lsp-bridge](https://github.com/manateelazycat/lsp-bridge)), but I've got the best results on `lsp-mode` with [lsp-booster](https://github.com/blahgeek/emacs-lsp-booster). + +<!-- ## Which Completion Provider? --> + +<!-- ## Which Package Manager? --> |
