Re: Using lua to define a macro with one optional parameter in brackets

[Jaroslav Hajtmar <hajtmar@gyza.cz>]

Hi Hans.
Only for explanation of my (maybe) crazy request:
I can not at this level TeX macros to create, because it creates 
automatically after opening the CSV file. Although I tried to start 
creating something with \ csname \ endcsname etc. but my experiments 
with this method were never successful. In addition with TeX probably I 
can not work as well as with Lua (for things which in this case I need 
ie. at low level). Given that I have a CSV file loaded in global 
variables and header information at my disposal, I Lua everything you 
need me to do what I need. The problem is that the macros created in Lua 
I sometimes do not work as well when I create TeX (during the cycle will 
automatically fall short values). I have a particularly bad experience 
in this regard with the construction, he sent Taco.

Simplified version of "interfaces.definecommand" construction does not 
in my way of processing the results of what I expected.

Module which at the moment I work (in collaboration with Pablo 
Rodriguez) at the moment is very complex and extensive, and already it 
slowly begin to lose myself :-), so I try to get any information from 
the conference.
Thank you and also to other counselors too at the conference for their 
cooperation in solve my problems.
