If you want to change the size according to resolution you can do something like this (adjusting the preferred width and resolutions according to your specific needs): (defun set-frame-size-according-to-resolution () (interactive) (if window-system (progn ;; use 120 char wide window for largeish displays ;; and smaller 80 column windows for smaller displays ;; pick whatever … Read more

But there’s nothing to compile in the case of a symbol. In general, it is used in … Read more
Here’s a thought: The macro binds a flet function (rails-project:root) one time to the value that (rails-project:root) has just before the body executes. (That’s how it claims a performance increase: Apparently the outer (rails-project:root) is expensive, so calling once and caching the value seems like a good idea.) Unfortunately, if there is code inside the … Read more

Most people have good success with simple incremental searches. See “foo” mentioned somewhere? Type C-sfoo, find the definition, press enter, read it, and then press C-x C-x to go back to where you were. … Read more
