[TxMt] Conditional insertion help

Hi all,

I made some snippets using conditional insertions for my declarations in Fortran. For example, I have this one :

real*${1:8}${2: a/d}${2/(,a)|(,d)/(?1:llocatable) (?2:imension)/}${2/,a|(,d)/(?1:())/} :: ${3:name}${2/,d|(,a)/(?1:())/} $0

which does that :

What I would like to do is, in the “allocatable” or “dimension” case, that the caret goes between the braces after I type in the name. In the snippet definition, that would be to somehow define a $4 key but I really don't know how to do this...

Any help is much appreciated :-)

PS : Once again, due to my poor knowledge of RegExp, if anyone has some suggestions/improvements for this snippet, he is quite welcome :-D
