8. Emacs? Old (1976) Elisp Powerful Decent editor (really!) Hundreds of packages Everywhere
9. Emacs? Old (1976) Elisp Powerful Decent editor (really!) Hundreds of packages Everywhere Old (1976) Kitchen sink Painful to configure Not modal M-x everything Built-in therapist
10. Emacs with a decent editor? viper-mode vimpulse VIP vi-mode evil
11. evil-mode extensible vi layer for Emacs https://gitorious.org/evil/
12. evil-mode As close to Vim as it will ever get (and it’s pretty close)
13. The evil good HJKL (duh) All major modes supported (insert, visual, etc) Text objects Emacs wiki Lisp
14. The evil good Splits Buffers Abbreviations Spelling Macros Integration with external tools
15. The evil ugly Command mode - missing q: -no C-r 0 (pasting from paste buffer into command) Abbreviations Tags - kinda there, but uses etags and it’s all weird Documentation Emacs Wiki
16. The evil dead Major and minor mode integration - fixable with plugins, but… Indentation Can’t avoid using Control/Alt/Shift in some cases
17. Why then? We deserve better first-class extension language in Vim. And people want it.
18. Why then? We deserve better first-class extension language in Vim. And people want it. That’s not going to change.
19. Why then? With a good foundation we can have best of both worlds.
20. Example { :key => “value” } { key: “value” }
21. Example function! ConvertHash() let @z="xf Pf=df " :normal @z endf nmap <leader>ch :call ConvertHash()<cr>
22. Example (defun ruby-convert-hash () (interactive) (delete-char 1) (search-forward " ") (delete-backward-char 1) (zap-to-char 1 ?>) (insert ":")) (evil-leader/set-key “ch” ‘ruby-convert-hash)
23. Example - abbreviations autocmd Filetype ruby iabbr {- { \|A\| }<ESC>FA"_xi
24. Example - abbreviations (define-abbrev-table 'ruby-mode-abbrev-table '(("bli" "{ |XXX| }" abbrevs-jump-to-placeholder 0)) (defun abbrevs-jump-to-placeholder () (search-backward "XXX") (delete-char 3))
25. Why use evil-mode if we have vim? It’s good enough!
26. Migrating Ctrl-P - Projectile - needs adding key bindings (I use <leader>p|P|d|T|t) Fugitive - Magit - doesn’t integrate at all but is as powerful as fugitive NERDtree - CEDET (good luck!) or Speedbar or at least 3 other solutions
27. “Fixing” magit ; done already - magit-status is an existing function (evil-ex-define-cmd "Git-status" 'magit-status) ; we will fill in the blanks (evil-ex-define-cmd "Git-remove" 'evil-git-remove-current-file) (evil-ex-define-cmd "Git-checkout" 'evil-git-checkout-current- file)
28. “Fixing” magit (defun evil-git-checkout-current-file () (interactive) (start-process "git-checkout" (get-buffer-create "*git-checkout*") "git" "checkout" buffer-file-name) (find-file-noselect buffer-file-name))
29. “Fixing” magit (defun evil-git-remove-current-file () (interactive) (start-process "git-remove" (get-buffer-create "*git-remove*") "git" "rm" "-f" buffer-file-name) (kill-buffer))
