Omni completion provides smart autocompletion for programs. When invoked, the text before the cursor is inspected to guess what might follow. A popup menu offers word completion choices that may include struct and class members, system functions, and more. A similar feature in Microsoft Visual Studio is known as IntelliSense.
Overview[]
Omni completion is not usually enabled by default. To turn on omni completion, add the following to your vimrc:
filetype plugin on set omnifunc=syntaxcomplete#Complete
Various programming languages are supported in Vim 7. For many languages such as SQL, HTML, CSS, JavaScript and PHP, omni completion will work out of the box. Other languages such as C and PHP will also take advantage of a tags file - if one exists. Omni completion using a tags file will complete the names of defined constants, functions, classes and other names from included and other external files. Omni completion scripts can be written to support other languages, and to customize behavior. :help new-omni-completion :help compl-omni
When generating a tags file, Exuberant Ctags should be used. Windows users need to install a recent version of Exuberant Ctags (Ctags 5.7, released September 2007, or newer, is recommended). :help ft-c-omni
Using omni completion[]
To use omni completion, type <C-X><C-O> while open in Insert mode.
If matching names are found, a pop-up menu opens which can be navigated using the <C-N> and <C-P> keys.
