yasnippet to expand abbreviation in dired/fileopen command?

[David Belohrad]

Hi there,
any help would be appreciated:

I want to open a file on the remote machine. I've setup tramp to use
abbrev to expand an abbreviation to full path, e.g.:

xhs -> //ssh:xxx@xxxx#1222:/mnt/mp3/

As I'm using already yasnippet for something else, using abbrev for this
seems to be just a duplication of what yasnippet does in more generic
way. 

However, as yasnippet is using set of directories to identify major mode
and select appropriate snippet 'set', I'm not sure into what directory I
should put my snippets so they get expanded only when I have to specify
directory or file....


any comments?

thanks
d.

I've never thought about this, but in general I think
1. this duplication is not the end of the world
2. bookmark (or bookmark+) are a better way to solve this problem.

What I do is normally just connect to a machine, open dired or the
desired file and C-x r m to store the bookmark..

That looks like expansion in minibuffer.  Afraid yasnippet
doesn't handle it by now.

As Andrea suggested, creating a bookmark is one (good) approach.

Here are two other approaches -

1. Option `directory-abbrev-alist'.
E.g., include an entry like this in the alist:
("\`xhs" . "//ssh:xxx@xxxx#1222:/mnt/mp3/")

Or in Customize:
 INS DEL From: \`xhs
           To: //ssh:xxx@xxxx#1222:/mnt/mp3/

Note that the doc for `directory-abbrev-alist' shows only examples where the
resulting directory names are shorter, but the reverse relation can be useful as
well: expand instead of contract - which is your case here.  The point is to
substitute one directory name for another that is more convenient in some way.
The symlink case is only one use case.

In vanilla Emacs, `C-x C-f xhs RET' will correctly expand the abbreviation if it
is in `directory-abbrev-alist'.  However, completion (`TAB') will not expand it.
If you use Icicles then completion will expand it, just like `RET' will.

2. Environment variables.  They are expanded even by vanilla Emacs during
completion (`TAB').  So you would define a variable `xhs' and then use `$xhs
TAB' in the minibuffer.


If you use Emacs on more than one machine, then using a bookmark or
`directory-abbrev-alist' is probably easier than using environment vars.  They
keep the customization within Emacs, not at the machine/OS level.

Dear All,
thanks for fruitful responses. I think I like this one below, because it
is very similar to what I use with tramp.

thanks

it looks like your expansion is static, so you don't really need
yasnippet for that. emacs abbrev feature will do.

here's examples of how

〈Using Emacs's Abbrev Mode for Abbreviation〉
http://xahlee.org/emacs/emacs_abbrev_mode.html

as to your specific question about yasnippet, i don't know the answer
but someone probably will answer.
