YASnippet (Yet Another Snippet) is a template system for Emacs. It allows you to type an abbreviation and automatically expand it into function templates. Bundled language templates includes: C, C++, C#, Perl, Python, Ruby, SQL, LaTeX, HTML, CSS and more.
Basic setup
(add-to-list 'load-path "~/.emacs.d/plugins/yasnippet")
(require 'yasnippet)
(yas/global-mode 1)
Helpful keybindings
- [Tab]
- Expand snippet.
Embedded Lisp
It is possible to embed lisp code directly in to snippet files by surrounding the s-expression with backticks (`). For example:
#name : document string
# --
-------------------------------------------------------------------------------
-- `(car (last (split-string (buffer-file-name) "/"))) ; finds last entry
; (filename) in the full path of the file`
-- Author: Author
-- Description: $1
-------------------------------------------------------------------------------
This snippet will extract the name of the buffer (which is presumably the file name) and add it to the second line of the expansion. Yasnippet is smart enough to ignore the comment at the end of the line as well.
Common Customization
Use Yasnippet with Hippie Expand
If you use Hippie Expand, you can add Yasnippet to the list of expansion functions. For example if you want to try expanding snippets first:
(setq hippie-expand-try-functions-list (cons 'yas/hippie-try-expand hippie-expand-try-functions-list))
You could do this globally, or for a specific mode using a mode hook.
