I get an output from tlpdb.tlu, which is unsorted. When I now use table.sort the output as a pdf is still unsorted.

tlpdb = read_tlpdb( kpse.var_value("SELFAUTOPARENT") )
table.sort(tlpdb)

Do I need a compare function for this?

  • This question belongs on stackoverflow.com, it's a question about the Lua language. – topskip Dec 19 '11 at 10:45
  • The code snippet is part of a tex document! – DanielG Dec 19 '11 at 11:29
  • That's a bit like asking about ls in the following example: \write18{ls}\bye. As far as I understand that question, it is about sorting a Lua table. Which is a Lua question to me. If you disagree, you should expand your example a bit more. Where is read_tlpdb defined? It is not from LuaTeX. Please write more to get better help. – topskip Dec 19 '11 at 11:39

    I presume the snippet is from question tex.stackexchange.com/questions/38131, I updated my answer there to show how to get a sorted list of table keys. – Tomek Dec 19 '11 at 12:04
