'figures.getinfo()' not to exit ConTeXt

["Procházka Lukáš Ing." <LPr@pontex.cz>]

Hello,

I'm using the following code, mentioned here some time ago, to get some info about PDF:

----
\startluacode
figures.getinfo = function(name, page)
     if type(name) == "string" then
         name = { name = name, page = page }
     end
     if name.name then
         local data = figures.push(name)

         --figures.identify()
local ok, res = pcall(figures.identify)
print(">>1", ok, res)

         --figures.check()
local ok, res = pcall(figures.check)
print(">>2", ok, res)

         figures.pop()
         return data
     end
end

local data = figures.getinfo("NonExisting.pdf")

\stopluacode
----

The problem is that once the PDF file doesn't exist, the function causes ConTeXt to exit, even when I enclose 'figure.check()' into the 'pcall' (to be handled like try/catch mechanism).

Is there a way so that the function 'figures.getinfo()' does't exit ConTeXt, it just returns 'nil', or even gives info which directories (or even which file types) were searched?

TIA.

Best regards,

Lukas
