Hello ConTeXist. Within the one very complex problem I need to solve the following case. I want using lua code to define a macro with one optional parameter in brackets. I tried it using commands context.setgvalue, or find something on the wiki (http://wiki.contextgarden.net/System_Macros/Definitions_and_Assignments), but each time I broke a tooth on it. Can you, please, someone advise how something can be it done? Suffice some reference to solve a similar problem. Thanks Jaroslav Hajtmar Here is my minimal example: \starttext \def\lastname{\dosingleempty\dolastname} \def\dolastname[#1]{\iffirstargument #1\else nothing\fi} \lastname \lastname[Smith] % Not working % \ctxlua{ % context([[\def\firstname{\dosingleempty\dofirstname}]]) % context([[\def\dofirstname[#1]{\iffirstargument #1\else {nothing}\fi}]]) % } % % \firstname % % \firstname['Peter'] \stoptext

Simplest solution I know is this: \startluacode interfaces.definecommand ('dolastname', { arguments = { { "option", "string" } }, macro = function (opt_1) if #opt_1>0 then context(opt_1) else context('nothing') end end }) interfaces.definecommand ('lastname', { macro = function () context.dosingleempty() context.dolastname() end }) \stopluacode Best wishes, Taco

Thanks Taco, your solution helped me ... Based on initial tests, it seems that it works correctly. I'll know more after thorough testing. Once again, thank you many times. Sincerely Jaroslav Hajtmar Dne 8. 7. 2015 v 12:07 Taco Hoekwater napsal(a):

Hi Taco. full deployment is unfortunately not working. Unfortunately I need to cycle create different macros whose names are variable. At this moment I can not deal with this: --- context.doxlsname() --- ????? Thanx Jaroslav Hajtmar here is another minimal example: \starttext \def\linepointer{5} \def\csvcell[#1,#2]{cell #1,#2} \directlua{ xlsname='A' interfaces.definecommand ('do'..xlsname, { arguments = { { "option", "string" } }, macro = function (opt_1) if #opt_1>0 then context('\\csvcell["'..xlsname..'",'..opt_1..']') else context('\\csvcell["'..xlsname..'",\\linepointer]') end end }) interfaces.definecommand (xlsname, { macro = function () context.dosingleempty() --- context.doxlsname() --- ????? end }) } \csvcell['Firstname',\linepointer] \A \A[5] \stoptext Dne 8. 7. 2015 v 12:07 Taco Hoekwater napsal(a):

Thanks Taco very much. At this point, it really works in simple situations, but in the event that this solution will incorporate into the existing system, then I have big problems with expansion (values are not updated in macros). I need more solutions using something like context.setgvalue, or at least according to the following example. If they could incorporate the remaining two definitions ie \def\simpleA {content when parameter is missing} \def\complexA[#1]{parameter #1} into luacode (probably encounter a problem with #), so it might work. Can not think of anyone, how it could be done differently? Thanks Jaroslav Hajtmar Here is minimal example: \ctxlua{ xlsname='A' content='content when parameter is missing' context([[\definecomplexorsimple\]]..xlsname) %context([[\def\simple]]..xlsname..[[{]]..content..[[}]]) %context([[\def\complex]]..xlsname..'[#1]'..[[{Neco: #1}]]) } \def\simpleA {content when parameter is missing} \def\complexA[#1]{parameter #1} \type{\A}: \A \type{\A[5]}: \A[5] \stoptext Dne 8. 7. 2015 v 14:11 Taco Hoekwater napsal(a):

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. Jaroslav Hajtmar Dne 8. 7. 2015 v 20:54 Hans Hagen napsal(a):

Thanks Hans. At this moment, it works fine. For me it is quite essential novelty and it is very much handy for me. It seems that works only in the standalone version because version in TeXlive 2014 version it tells an error message (but does not matter on it). I want to even ask how you can write a macro with one or more parameters? Now the parameter in square brackets displayed together with the contents of the macro. You can do this at all? It would get any minimal example? Thanks again for your support. Jaroslav Hajtmar Dne 9. 7. 2015 v 17:24 Hans Hagen napsal(a):
