The subsequent children are function parameters. The first child is always the return type, void. LookingĪt the Speedbar, under set-cpu-active node, it contains these Speedbar moves to the location of that tag and highlight it. That's what happens when you press RET on a tag: Sr-speedbar window using either the mouse or windmove.ĭemo: In the demo, you can see that the function set-cpu-active isīeing highlighted. You can prevent C-x o to jump to sr-speedbar window by setting. C-x 1 deletes every window except Speedbar, so you won't have to. Use an Emacs window instead of frame, make it easier to use. Automatically switches directory tree - when you switch buffer - to. Sr-speedbar gives the following improvements: To close sr-speedbar, execute the command sr-speedbar-close orīest is to use sr-speedbar-toggle only, for simplicity. 
To open sr-speedbar, execute the command sr-speedbar-open or. Issue, you need sr-speedbar, which can be installed via However, you may feel that a frame is difficult to use. b switches to buffer list using Speedbar presentation. M-n or M-p moves to next or previous node at the current level. That file if node is a directory, enter that directory if node isĪ tag in a file, jump to the location of that tag in the file. RET to open the node in another window. 
Use SPC to open the children of a node. Programming languages listed, consider adding it the regexp list. That match speedbar-file-regexp, that contains the extensions forĬommon programming languages. One important thing to remember, Speedbar only lists files The node is a directory, the children of the node are files in thatĭirectory. The files are tags (variable and function definitions) of the file if In this directory, to the left of a file orĭirectory name is an icon with + sign in it. To use Speed bar, M-x speedbar and a frame that containsĪ directory tree appear. If you want a static outline tree, Emacs also has a more one: ) ( require ' helm-gtags ) Enable helm-gtags-mode (add-hook 'dired-mode-hook 'helm-gtags-mode ) (add-hook 'eshell-mode-hook 'helm-gtags-mode ) (add-hook 'c-mode-hook 'helm-gtags-mode ) (add-hook 'c++-mode-hook 'helm-gtags-mode ) (add-hook 'asm-mode-hook 'helm-gtags-mode ) (define-key helm-gtags-mode-map (kbd "C-c g a" ) 'helm-gtags-tags-in-this-function ) (define-key helm-gtags-mode-map (kbd "C-j" ) 'helm-gtags-select ) (define-key helm-gtags-mode-map (kbd "M-." ) 'helm-gtags-dwim ) (define-key helm-gtags-mode-map (kbd "M-," ) 'helm-gtags-pop-stack ) (define-key helm-gtags-mode-map (kbd "C-c " ) 'helm-gtags-next-history )īefore using the ggtags or helm-gtags, remember to create a GTAGSĭatabase by running gtags at your project root in terminal: Internet connection is too slow for my guide, you can always clone and Please remember that there's a table of content on the top rightĬorner and you can use it to navigate this guide. Inside Emacs effortlessly, such as jump to definition/references atĬursor, go back and forth between jumping points, finding any file This guide, you should be able to browse the Linux kernel source tree #Best emacs for mac code#
Despite looking long, the setup is short and easy (mostlyĬopy/paste Emacs Lisp code into your init.el) most of the guide areĮxplanations and demonstrations of many useful features. In this guide, I will help you to setup an efficient working C/C++Įnvironment.
