Advanced readline support (5.2, 5.1, 5.0)

This patch adds the following features to the existing readline support in Lua 5.x:

 

• Completion of keywords and global variable names.
• Recursive and metatable-aware completion of variable names.
• Context sensitive delimiter completion.
• Save/restore the history to/from a file (LUA_HISTORY env variable).
• Set a limit for the size of the history (LUA_HISTSIZE env variable).
• Set the app name to allow for $if lua ... $endif in ~/.inputrc.

After applying the patch start Lua and try these (replace ~ with the TAB key):

~~
fu~foo() ret~fa~end<CR>
io~~~s~~~o~~~w~"foo\n")<CR>
