Hi, 
one never really escapes the escape tunnel.
I have a new problem with escapes.
>From the command line I can ask
TextMate to insert a backslash:

osascript -s 'tell app "TextMate" to insert "\"'

I want to do the same from a javascript
contained in an a href link. But I can not find the
correct way to escape things. Allan's suggestion
works perfectly with ordinary text; the following
html code:

<a href="javascript:TextMate.system(&quot;/usr/bin/osascript &>
/dev/null -e 'tell app \&quot;TextMate\&quot; to insert 
\&quot;TEXTTOINSERT\&quot;' &amp;&quot, null);">
TEXTOFLINK</a><br>

produces a link TEXTOFLINK and when I click on it,
TEXTTOINSERT is inserted into TextMate. But if
TEXTTOINSERT contains a backslash, it is ignored.
A pity since I want to insert a tex command...
What should I write instead of TEXTTOINSERT to
get, say, "\eqref" to be inserted? Yes, I am escape-blind.
Thanks for any help,

Piero

PS hm... no one seems to like my new idea for label 
completion. I'll keep it for personal use :)

Use \\ for one backslash in JavaScript strings.

I am not that blind, I tried \eqref, \\eqref, \\\eqref,
\\\\eqref... up to six (!) but the backslash is not
inserted: only "eqref" or nothing at all, depending
on the number of slashes.
I'll try again since the word of the master is beyond doubt, but...

Yeah, you would actually need 4 or 8 here. 2 for the actual  
AppleScript string, but this is inside a JavaScript string, so both  
needs escaping (so total is now 4) -- depending on how you produce  
the JavaScript, you may need to again escape each, making it now 8.  
This would be the case if you use e.g. echo with a double-quoted  
string. In single-quoted strings or here-docs you would not need to  
escape \.

I confirm what I said: it does not work. Try the following html:

<a href="javascript:TextMate.system(&quot;/usr/bin/osascript 
	&>/dev/null -e 'tell app \&quot;TextMate\&quot; to insert 
	\&quot;\\eqref\&quot;' &amp;&quot, null);">try</a>

A link is produced but if you click on it nothing happens. (if you
put \eqref instead of \\eqref, the text "eqref" is inserted).
Sorry! something here really escapes me, as usual

Piero

Lovely! eight escapes does the trick.

It's always going to be 2^(number of times the slash is escaped) - so  
six would never be right :)

Well, at least it is not an odd number :)))
