    <p>I'm starting to experiment a bit with using emacs as my development envrionment and I am running into a bit of trouble. I wish to use cscope with semantic for a fairly robust way of searching through my code base. However, after installing cscope (with <code>apt-get install cscope</code>) and moving <code>xscope.el</code> into my <code>~/.emacs.d/</code>, I am still having trouble calling some settings with my .emacs file. When I try to call <code>(semanticdb-enable-cscope-databases)</code>, I get an error that the symbol's function definition is void. I am using emacs 24.3</p> <pre><code>(semantic-mode 1) (global-ede-mode 1) (require 'semantic/ia) ;; Semantic (global-semantic-idle-completions-mode t) (global-semantic-decoration-mode t) (global-semantic-highlight-func-mode t) (global-semantic-show-unmatched-syntax-mode t) ;; auto-complete stuff (add-to-list 'load-path "~/.emacs.d") (require 'auto-complete-config) (ac-config-default) (add-hook 'c-mode-common-hook '(lambda () ;; ac-omni-completion-sources is made buffer local so ;; you need to add it to a mode hook to activate on ;; whatever buffer you want to use it with. This ;; example uses C mode (as you probably surmised). ;; auto-complete.el expects ac-omni-completion-sources to be ;; a list of cons cells where each cell's car is a regex ;; that describes the syntactical bits you want AutoComplete ;; to be aware of. The cdr of each cell is the source that will ;; supply the completion data. The following tells autocomplete ;; to begin completion when you type in a . or a -&gt; (add-to-list 'ac-omni-completion-sources (cons "\\." '(ac-source-semantic))) (add-to-list 'ac-omni-completion-sources (cons "-&gt;" '(ac-source-semantic))) ;; ac-sources was also made buffer local in new versions of ;; autocomplete. In my case, I want AutoComplete to use ;; semantic and yasnippet (order matters, if reversed snippets ;; will appear before semantic tag completions). (setq ac-sources '(ac-source-semantic ac-source-yasnippet)) )) (require 'xcscope) (semanticdb-enable-cscope-databases) ;;This is causing problems ;;C mode (require 'cc-mode) ;;Color theme (require 'color-theme) (setq color-theme-is-global t) (add-to-list 'load-path "/home/bob/.emacs.d/theme/ample-theme/ample-theme.el") ;;(require 'ample-theme) (eval-after-load "color-theme" '(progn (color-theme-initialize) (color-theme-jsc-dark))) ;;set font (set-face-attribute 'default nil :family "Anonymous Pro" :height 140) ;;line numbers (global-linum-mode 1) (custom-set-variables '(linum-format (quote "%4d \u2502 "))) ;;treat .h files at C++ (add-to-list 'auto-mode-alist '("\\.h\\'" . c++-mode)) ;; use F5 as compile (global-set-key [(f5)] 'compile) ;; make compilation window smaller (setq compilation-window-height 8) </code></pre>

    1. CO`semantic--tag-deep-copy-value` is only available when `semantic/scope.el` is loaded. Put the function into the appropriate mode-hooks or into `eval-after-load`. I do not think that putting `.emacs.d` into `load-path` is such a good idea. That directory is for configuration. I put my personal library files rather in `~/share/emacs`.

    2. CO@Tobias, thanks! so this would mean that I need to call (require 'semantic/scope) correct? I'll move my emacs packages.

    3. CO@Tobias, I added (require 'semantic/scope) to the top of my dotfile and it still can't detect semanticdb-enable-cscope-database

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
