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

[Jaroslav Hajtmar]

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

i would not do that in lua but in tex and load a module with those macros

much less hassle

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

[Jaroslav Hajtmar]

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.

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

[Jaroslav Hajtmar]

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]

Thanx Taco for reply.

It works for me after changing \directlua {} to \startluacode … \stopluacode

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

[Jaroslav Hajtmar]

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]

why don't you define these commands at the tex level

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

[Jaroslav Hajtmar]

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

Perhaps interfaces.definecommand could be extended with a way to do global definitions?

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

[Jaroslav Hajtmar]

Thanx to Hans and Taco too,

ad Taco) ala Perhaps interfaces.definecommand could be extended with a 
way to do global definitions?
Indeed it seems to me. Changes in lua code does not affect the results 
in ConTeXt.

ad Hans) interfaces.setmacro("name","value")

Thanx, II tried to use it, but somehow I can not realize what I wanted. 
Not available somewhere a minimal example? I tried to scan codes in the 
folder with the installation of ConTeXt, but I never encountered a 
working example of where you could bounce.
Thanks Jaroslav Hajtmar

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

[Jaroslav Hajtmar]

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
