You've made my day with this formatting style!
Probably minimal change to make your code work is move "cols = {}" inside
"for _,v in ipairs(rows)" cycle:
for _,v in ipairs(rows)
do local a = '_'
local b = 0
local c= '_'
a,b,c= string.match (v, "(%w+)|(%d+)|(%w+)") -- parse the line
print (a,b,c)
cols= {} -- a hash ie nam,val -- use pairs
cols['v1']= a -- populate the hash (table)
cols['v2']= b
cols['v3']= c
-- for kc,vc in pairs (cols) do print(kc,vc) end
table.insert (dsn1, cols)
-- dsn1 [ #dsn1+1 ]= cols -- gives same result: every row in dsn1 is the last
row from input file
end
I'd highly recommend to consider snippets from Sean Conner or Russel Halley.
