Re: test suite for Lua 5.2 alpha

[Henning Diedrich <hd2010@...>]

Hi Leo, hi Liuz,

the prompts simply don't show up when redirecting input from file

on Mac OS 10.5.8 / Darwin Kernel Version 9.8.0 i386 for 5.2.0-alpha

This is different from 5.1.4 (5.1.4 not compiled with its test libs in, if that makes a difference).

Note the missing ">":

$ echo "print(1)" > in
$ ../src/lua -i < in

$ lua -i < in

It does not make a difference whether I use a pipe or an input re-direction.

Thank you very much Leo, for hinting at that possible problem so quickly, but it was not it. The fact that only the last of the four tests using < failed also made it unlikely.

Setting the prompt doesn't help either, it is having no effect

$ echo "print(1)" > in
$ ../src/lua "-e_PROMPT='alo'" -i < in

$ lua "-e_PROMPT='alo'" -i < in

aloprint(1)

If you don't redirect or pipe in, the prompt shows up as it should:

$ ../src/lua "-e_PROMPT='alo'" -i
