This makes quickrun, *doom eval* and *Pp Eval Output* buffers behave
better.
Eval output buffers should a) shrink themselves to the size of their
output (within reason), b) *not* grab focus, and c) be easy to close
from afar with C-g/Escape.
Gotchas:
1. Quickrun gets output asynchronously, so we shrink it on
quickrun-after-run-hook, not in the popup rule.
2. *doom eval* and *Pp Eval Output* opens with its output ready, so the
popup system may shrink those to fit.
3. *doom eval* and *Pp Eval Output* handle window selection themselves.
Let them by setting the select window parameter to #'ignore.
This is a breaking change! Update your :popup settings. Old ones will
throw errors!
Doom's new popup management system casts off its shackles (hur hur) and
replaces them with the monster that is `display-buffer-alist`, and
window parameters.
However, this is highly experimental! Expect edge cases. Particularly
with org-mode and magit (or anything that does its own window
management).
Relevant to #261, #263, #325
Which takes :definitions, :references, :documentation and :xref-backend.
Each accepts a function that will jump to definitions, references, and
documentation respectively.
If a major-mode has an :xref-backend, you don't need :definitions or
:references.
Editorconfig in Lisp enforces lisp-indent-offset too strictly, ruining
its adaptive indentation. We don't want to disable it complete in those
modes however. In all other respects (controlling spaces vs tabs,
charset, max_line_length, etc) editorconfig is great.
+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
