How to make vim-fake compatible with UltiSnips?

Question

For generating different placeholders like emails, names, and passwords, vim-fake looks like a really useful tool. The problem is that I'm using UltiSnips and vim-fake is seemingly designed for neosnippet—the snippets can be found here. Taking this simple code which is written for neosnippet,

snippet fakeint
abbr    fake#int()
options word
    `fake#int()`

Is there any way to write something equivalent for UltiSnips environment? I already tried the following codes but got no results.

snippet fakeint
`fake#int()`
endsnippet

and also,

snippet fakeint
`echo fake#int()`
endsnippet

The syntax to use a Vimscript expression in UltiSnips is `!v ...`, so I think what you're looking for is:

snippet fakeint
`!v fake#int()`
endsnippet

See :help UltiSnips-vimscript for all the details.

Note that you don't necessarily need to use a snippet manager to use the vim-fake functions, in Insert mode you could simply use CTRL-R = to insert the contents of an expression, then type the expression itself fake#int() (note that Tab completion should help you here) and finally press Enter.

This technique should allow you to insert the result of any Vimscript expressions in your text without having to configure them in your snippet manager.
