Hello all. It is GREAT! Thanx Hans and Wolfgang too. It is very instructive and inspiring for me... I was looking for something similar for a long time, but I have not found anything (not even in the CLD-MKIV and others ...). Finally, after yours reply to this email find something in the ctx-man.pdf from 1997 year :-). But I have a few questions and comments on this subject: 1. Is there any possibility to do anything similar with counters, dimensions etc? I trying but without success. For example: context.newcount(mycounter) or context.newcounter(mycounter) context.mycounter=5 etc. or it must be realized by classical way: context('\\newcount\\mycounter') context('\\mycounter=10') context('\\advance\\mycounter by5') context('\\the\\mycounter') similary with \newdimen, \newif etc... 2. Any person interested in using context.setvalue{"Mymacro",somevalue) and context([[\def\MyMacro#1{#1}]]) syntaxes I have pointed out that the second syntax only operates when the command is given in a separate LUA file (ie file.lua) (ie not within an environment \startluacode - \stopluacode in classical TEX file!!!). Hans told me once that it is the individual categories of characters (backslash??) (if I remember correctly). First syntax works perfectly in LUA and TeX files too. Here I have a question. Why not comment out this case in TEX file? \startluacode -- context([[\def\macro#1{#1}]]) \stopluacode I get error: ! Undefined control sequence. -- context([[\def \macro #1{#1}]]) \dodostartluacode ...and \directlua \zerocount {#1 }} l.25 \stopluacode ? That category characters again? Comment character -- works differently in TEX file, and otherwise in the LUA file? Ie. comment on the backslash? 3. Wolfgang write about using context command \convertnumber{R}{1400} and the corresponding syntax: context.convertnumber("R",1400) to roman converting. It is great, but I could not figure out how to use in combination with the above syntax (ie use case context.command) or find the appropriate conversion LUA function (I did not use a custom function). Is there any way to do something like that: context([[\def\Macro%s{Macro%s}]],context.convertnumber("R",1400),1400) ??? ie. TEX command is used as a LuaTeX parameter?

whatever you like best
context.setvalue{"Mymacro",somevalue)
context([[\def\MyMacro#1{#1}]])
Exist other (best or most optimal) way to do? for i = 1, 10 do tex.sprint(tex.ctxcatcodes,'\\def\\macro'..ar2rom(i)..'\{macro '..i..'\}') context('\\def\\Macro'..ar2rom(i)..'\{Macro '..i..'\}') end
for i = 1, 10 do context([[\def\Macro%s{Macro%s}]],ar2rom(i),i) end
When more than one argument is given, the context command treats the first argument as format template.
By using the context command you can see what happens with
\enabletrackers[context.trace]
