C++ iterators for Lua tables #72

Open thinlizzy opened 8 years ago

thinlizzy commented 8 years ago

Any plans on adding iteration capabilities in sol::table ?

ThePhD commented 8 years ago

Try using

sol::table t = ...;
t.for_each( /* function that takes key, value */ ) ;

Note that this is only present in the develop branch of sol.

error: 'class sol::table' has no member named 'for_each'

Please pull from the develop branch of Rapptz/sol (you're currently using the master branch) to get more updated features, or use the experimental version 2 of the library here.

Hi! Does the develop branch also support checking if a table key exists?

I've seen sol2 has sol::optional, which also works for me. Perhaps I should early migrate to sol2, instead of trying the develop branch?

Yes. sol2 is no longer experimental and has support for the features you're looking for.
