Very nice article. What do you mean by a system-wide executable here,
though? Could we just check for an attribute "lang" or something, and take
that to be the interpreter that will execute the (escaped) code in the src
parameter?
e.g.
<eval src="a = rand(99)+1; b = rand(99)+1; puts \"#{a} * #{b} = #{a*b}\""
lang="ruby"/>
Mnemosyne could just dump the src value to a temporary file and call the
specified interpreter (in this case "ruby tmp"), capturing the standard as
the result of the <eval>?
While I love the idea, I'm finding it hard to come up with simple-to-write
dynamic cards that would really be useful, outside of perhaps some
mathematical things like this or long division.
Oisín
p.s. I tried to write that example in Lua just now and discovered that you
need to give a random seed to get different outputs on each run, AND Lua
doesn't offer any time function which gives better than second resolution
(i.e. less useful for random seeds) AND the random number generator on BSD
or at least my Mac is shockingly bad, giving almost identical results for
two random seeds which are close together in value. Boo hiss.
