1. I would like to create a snippet like (actually a part of a

snippet)

${1:[${2:text}]}

So when I insert it on the first tab I have

[text]

with the option of deleting it typing <delete> and then on the second tab to modify the actual placeholder. The problem is when I replace the square brackets [] with curly brackets {}. I have tried a few options with mirror and conditional insertions but to no avail. Any suggestions?

Try: ${1:{${2:text}}}

Thanks. It works. I thought I have tried the solution above :-( but maybe I have not saved the file (it was called from latex configuration file)

Anyone with any suggestion for the other issue?

2. I would like to have a snippet for LaTeX superscript (and

subscript) such that curly brackets are included when the content is at least two characters and no brackets when I have only one character, that is "^{abc}" and "^a".

So far I have the following solution

^${1/(.{2,})|./(?1:{)/}$1${1/(.{2,})|./(?1:})/}$0

but there is a few problems. When I have nested superscript (or subscripts) if the nested supscript is inserted as second character, then the caret is not at the right place. So if I type

^a^

I get

^{a|^}

where | indicates the position of the caret. The second problem is that if the first command triggers a snippet of a command, the snippet no longer work.
