One of the benefits of using the one true editor
!) is that you
get more features than you ever knew you'd need. One of these features
, written by Anders Holst.
Basically, when you invoke hippie-expand, it tries to expand (much
like tab completion the word you are currently typing by matching it
- file names - hippie-expand scans your file system to see if it
looks like you are trying to type the name of a file or directory.
- the current buffer - hippie-expand looks in the current buffer
(and other buffers on failure) to see if the word you are typing
matches an already existing one.
- exact line match - hippie-expand checks if there exist lines with
the current line as prefix.
- the kill buffer - hippie-expand also scans the kill ring to see
the text there matches what you are typing.
All in all, it's an extremely useful feature
, especially if you are
coding and have to use long variable
. It's not turned on by default, but that's easily remedied if
you stick something like
(global-set-key (quote ) (quote hippie-expand))
in your .emacs file. This particular example ties hippie-expand to the
key above TAB and to the left of 1 on a swedish keyboard (no-one ever
uses that key anyway).
