Useful Blog Comments
Nachopp demonstrates some emacs lisp that inserts a commonly used find command in a shell buffer. And Ian Eure has a great follow-up comment which demonstrates the more typical way of defining emacs lisp functions; talks about alternatives such as
abbrev mode and
yasnippet and finally mentions the best solution, the built-in
Defining C++ styles
David Ha has a gallery of some of the built-in C++ styles. None of the styles suit me exactly so I have accreted a fair amount of C++ configuration code over the years. I must admit, I haven’t audited for ages so I’m not sure which bits are necessary and which are not.
(defconst *my-cc-style* '((c-basic-offset . 4) (c-comment-only-line-offset . 0) (c-hanging-braces-alist . ((brace-list-open) (brace-entry-open) (substatement-open after) (block-close . c-snug-do-while))) (c-cleanup-list . (brace-else-brace)) (c-offsets-alist . ((statement-block-intro . +) (knr-argdecl-intro . 0) (substatement-open . 0) (substatement-label . 0) (innamespace . 0) (case-label . +) (statement-cont . +))))) (defun my-c-initialization-hook () (define-key c-mode-base-map "\C-m" 'c-context-line-break) (define-key c-mode-base-map (kbd "RET") 'newline-and-indent) (define-key c-mode-base-map [f7] 'run-compile)) (add-hook 'c-initialization-hook 'my-c-initialization-hook) (setq c-offsets-alist '((member-init-intro . ++))) (c-add-style "PERSONAL" *my-cc-style*) (defun my-c-mode-common-hook () (c-set-style "PERSONAL") (setq tab-width 4 indent-tabs-mode nil c-hungry-delete-key t) (c-toggle-auto-newline 1)) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
The most useful commands for finding out which of the variables to set are
C-c C-o (c-set-offset) and
C-c C-s (c-show-syntactic-information)
This is kinda interesting where Ronnie Collinson (from the NotThinking blog)
removes the *compilation* buffer if the compile is successful. It isn’t something I personally would use as I like the feedback, but I wasn’t previously thinking about
compilation-finish-functions and I have a few ideas of things I would like to run after a successful compile.
Perennial Emacs Blog Topics
There are a few perennial blog topics in the emacs world – I mentioned a smooth scrolling post in my links from 2009/17 and here is Da Zhang’s take (does anyone like the default behaviour by the way?). I included a link to a post on the incredibly useful mark ring in emacs-links-2009-09 and here is another from yesterday.
Proposed solutions – fix the smooth scrolling behaviour so it works nicely out of the box and… well, perhaps blogs are not a great way of educating the masses after all. Pity.
