Dear all,
It may be a slight off topic.
In the following example, I copied a table “m” to “tempM”, and remove the last
row of tempM.
Then the output is “ 2, 2”
I checked the contents of tempM and m and found that they are same even though
I didn’t touch m.
I want to remove the last row of tempM while keeping the table m untouched.
Please tell me how to do it.
\startbuffer[test]
\startluacode
local t1 = {{0, 2, 4},{2, 3 , 4}, {2, 2, -6}}
local t2 = t1 -- t2 points to t1
local t3 = table.copy(t1)
table.remove(t3)
context.tocontext(t1)
context.tocontext(t2)
context.tocontext(t3)
\stopluacode
\stopbuffer
\starttext
\getbuffer[test]
\stoptext
Thank you.
Best regards,
Dalyoung

context(#tempM, “, ” , #m)
