Use math in PhpStorm's Live Template

Question

How can I use math in PhpStorm's Live Template?

For example, I have $Image_width$ in my template and want to set height image something like this:

<img width="$Image_width$" height="($Image_width$ / 2)">

You can use groovyScript() function to define custom expressions - see https://www.jetbrains.com/help/phpstorm/template-variables.html#predefined_functions.

For example, for template like:

<img width="$Image_width$" height="$Image_width_half$">

you can specify groovyScript("def res=_1 as Integer; return res /2 ", Image_width) as expression for $Image_width_half$ variable:

_1 here is a reference to first variable passed as a parameter to groovyScript() function
