Re: making tables with lua

Re: making tables with lua

[Jeong Dal]

Dear Proch?zka Luk?? Ing and Hans,

Thank you for the reply.

It works fine.

I modify your code to write a matrix and it also works too.

\startformula
\startluacode
local NC, NR = context.NC, context.NR
local t = {{1,0,3,4},{0,2,-2,5},{0,0,1,2}}
context.startmatrix() --"{left={\left (\,},right={\,\right)}}")
for _, r in ipairs(t) do
for _, c in ipairs(r) do
NC()
context(c)
end
NR()
end
context.stopmatrix()
\stopluacode
\stopformula

But I couldn't put "( )" before and after matrix.
If I use
context.startmatrix("{left={\left (\,},right={\,\right)}}")
then it wrote "left…" as text before the matrix.

How to enclose matrix with (  )?

Thank you again.

Best regards,

Dalyoung

Dear Wolfgang and Proch?zka Luk?? Ing,

Thank you for the solution.
It works nicely. It is so convenient to write many matrices.

Re: making tables with lua

[Procházka Lukáš Ing. - Pontex s. r. o.]

[-- Attachment #1: Type: text/plain, Size: 3053 bytes --]

Hello,

my experience is that the best way is to create the table first, then to call Lua function to typeset the table.

You may choose whether the table will be typeset with 'tabulate' family functions or 'TABLE' family; I may recommend you the latter as it gives you much more control of the final look than the former; 'TABLE' is much better anyway.

Once you have such functions prepared, you just select to type:

printTabulate(mytab) -- via 'tabulate'

or

printTABLE(mytab) -- via 'TABLE'

If you insist on 'tabulate' family, you could use the following snippet for your start:

----
\starttext
   \startluacode
     local tab = {{1,2},{3,4}}

     printTabulate = function(tab)
       context.starttabulate{"|" .. string.rep("c|", #tab[1])}
         context.HL()
         for _, r in ipairs(tab) do
           for _, c in ipairs(r) do
             context.VL()
             context(c)
           end
           context.VL()
           context.NR()
           context.HL()
         end
       context.stoptabulate()
     end

     printTabulate(tab)
   \stopluacode
\stoptext
----

You can write a similar function(s) to typeset via 'TABLE'.

Best regards,

Lukas

making tables with lua

[Jeong Dal]

Dear all,

I used code which generates the table as following:

\startluacode
local NC, NR, HL, VL = context.NC, context.NR, context.HL, context.VL
context.starttabulate { "|c|c|c|c|c|c|c|c|c|c|" }
HL()
for i=1, 6, 1 do
	for j=1,10 ,1 do
		k= i % 3
		if k==1 then
			VL() context(10*(i - k)/3+j)
		else
			VL()
		end
	end
	VL()
	NR()
	if k==0 then
		HL()
	end
end
context.stoptabulate()
\stopluacode

But it has a fixed column definition as "|c|c|c|c|c|c|c|c|c|c|" and the number of columns.
I wonder it is possible to use the variable for "j" to control the number of columns and the column setting.
Of course, I may put similar codes  which are different only in the number of columns and column settings when I need a table.
But I have many similar tables whose number of columns are different only.
If such a method is possible, I'd like to put such a code in \startbuffer…\stopbudffer and call it to generate tables of various number of columns given at each time. 
I also don't know whether it is possible to convey a number from ConTeXt to the variable in Lua code.

I write this email because I saw a hope in recent discussion "Re: Fwd: Need help with \definetabulate" which has a method to vary the column setting.

\definetabulate
[whatever]
[|l|r|]

\definetabulate
[whatever][else]
[|l|c|r|]


It may be a lazy man's question with no need for others.

Thank you for reading.

Best regards,

Dalyoung
