This fixes a problem where calling IRC (e.g. C-c I I) will switch to
a (seemingly random but is ordered by load order) buffer.
It also adds a `user-error` when the IRC workspace is already selected.
:feature was a "catch-all" category. Many of its modules fit better in
other categories, so they've been moved:
- feature/debugger -> tools/debugger
- feature/evil -> editor/evil
- feature/eval -> tools/eval
- feature/lookup -> tools/lookup
- feature/snippets -> editor/snippets
- feature/file-templates -> editor/file-templates
- feature/workspaces -> ui/workspaces
More potential changes in the future:
- A new :term category for terminal emulation modules (eshell, term and
vterm).
- A new :os category for modules dedicated to os-specific functionality.
The :tools macos module would fit here, but so would modules for nixos
and arch.
- A new :services category for web-service integration, like wakatime,
twitter, elfeed, gist and pastebin services.
For consistency with other app modules:
+ Refactor out s.el dependency
+ Reorder variables (public then private)
+ Use add-hook! instead of add-hook+lambda
+ Optimization: replace mapcar+closure with cl-loop (reduces allocations)
+ Replace evil-set-initial-state with (set! :evil-state ...), which is
ignored if :feature evil is disabled.
