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
