[texworks] Lua Extension - put into Sentance Case, Trim, Date Time, lowercase, uppercase

[Paul A Norman]

Thanks Stefan,

I think we are in different time zones! I'm GMT + 12.

I am ignorant! and dont know anything about how "QT Script" would be bound
to TW, and have to admit that I thought it would be stringently gated with
access strictly proscribed. I am envisaging only text substitution in the
editor, no binary return packets accepted, and no provsision for any further
executioin in "QT Script" on the returned packet.

I "assume" that's also what Lua does with
http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/  aqnd the like,
unless you leave the door open the response is strictly channelled? Well, it
should be!

Paul
